摘要： PURPOSE: To detect abnormality of a fuel supply system which is generated after judgment of influence of purging without deteriorating operability by prohibiting execution of abnormality judgment of the fuel supply system until an air-fuel ratio correction factor is increased under the state that evaporated fuel is supplied. CONSTITUTION: An ECU 5 receives output signals of a throttle valve opening sensor 4, an engine speed sensor 13, and O2 sensors 18L, 18R on an upstream side of a catalytic converter rhodium 15, and judges an operation condition. According to the judgment result, fuel injection time of a fuel injection valve 6 is computed. Abnormality occurrence of the fuel supply system is judged when an air-fuel ratio correction factor is increased upon stoppage of supply of evaporated fuel under the state that the air-fuel ratio correction factor based on the output of the O2 sensors 18L, 18R is lowered to a specified value or less. After judgment of normality, supply of evaporated fuel is restarted. Until the air-fuel ratio correction factor is increased under a supply of the evaporated fuel, abnormality judgment of the fuel supply system is prohibited.

摘要： PURPOSE:To provide the slip casting method and a composition for a mold without generating deformation or cracks on a molded body. CONSTITUTION:A mold 1 is molded and dried by using a polyethylene glycol as a binder, very fine irregular spherical carbon as an aggregate and water as a slurry medium. A slip is cast into gypsum split molds 2a-2c. A molded body 4 thus formed is dried in the state of removing the gypsum split molds 2a-2c after the slip is solidified. After that, the molded body 4 is heated in the atmosphere at the temperature of 500 deg.C for one hour to burn down the mold 1 completely.

摘要： PURPOSE:To avoid the influence from error of an executive value with respect to a set value, in a control method for an engine which is constituted in such a way that stepwise switching control of valve operating characteristic is made possible on the basis of engine condition, and also slip of a driving wheel can be suppressed by control for making an air fuel ratio lean. CONSTITUTION:Setting of valve operation mode switching engine speed during traction control (under execution of control for making an air fuel ratio lean), is shifted to higher value in comparison with that in a normal time, and the width of hysteresis of a valve operation mode switching point during traction control is set to larger value in comparison with that in the normal time. Or the air fuel ratio at the time of a high speed mode is set richer in comparison with that at the time of a low speed mode.

CONSTITUTION:A throttle valve 3 is provided on the intake pipe 2 of an engine 1, and the signal of an opening sensor 4 is inputted to a control unit (ERG-ECU) 5 for engine control. A ternary catalyst 14 is provided in an exhaust pipe 13, and exhaust gas concentration is inputted to the ERG-ECU 5 by an O2 sensor 12. A solenoid valve 16 is opened and closed according to the output signal of the ENG-ECU 5, and a valve timing mechanism 19 is controlled through a selector valve 17. The ENG-ECU 5 judges the present valve timing area by signal inputs of various sensors and an electronic control unit 20 for driving wheel slip detection, and compares it with the inputted slip value duty to select a TC level. According to this mechanism, the TC level as giving no inconvenience on exhaust gas characteristic and catalyst protection is selected.

摘要： PROBLEM TO BE SOLVED: To provide a slip cast molding tool for manufacturing a ceramic molding body of sophisticated shape in a short time without generating shrinkage cavities, minimizing excessive wall generating amount and releasing easily without generating cracks and deformations. SOLUTION: A slip cast molding tool is provided with a cavity formed by a non-water absorption mold 27 and communicated with a water absorption slurry feed line 28 and a core mold of water absorption properties, and directional coagulation is carried out all through from a cavity area being in contact with a water absorption mold to a cavity area being in contact with the non- water absorption mold 27 through a cavity area being in contact with the core mold. The wall-forming speed by the core mold is slower than the wall-forming speed by the water absorption mold and well-balanced. After slurry is solidified up to the cavity area being in contact with the non-water absorption mold 27, mold opening is carried out, and then the formed body is dried without removing the core mold from the formed body, and then the core mold is removed by heating.

摘要： PROBLEM TO BE SOLVED: To enable compressive stress and tensile stress to be freely given to an optional position of a member with a simple operation by using a jig of the quality of material having the coefficient of thermal expansion different from the member to heat or cool the jig fitting loose on the member. SOLUTION: A jig is shaped such that one of the jig and a member fit loose on the other, while the quality of material of the jig is selected to have the coefficient of thermal expansion different from the member. When the jig and member are heated or cooled according to the loose fitting relationship between the jig and member, a difference between the coefficients of thermal expansion of both applies a predetermined compressive or tensile stress to the member to enable the inspection of the member strength while enabling the measurement of the stress or strain of a hard member. For example, the member 2 has two projection parts 21, 22. A rod-like jig 5 is loose fitted between these two projection parts 21, 22 to be heated and cooled, so that the tensile stress can be given to the root parts of the two projection parts 21, 22 of the member 2.

摘要： PURPOSE:To make the casting rate larger by enhancing the water absorbing speed to a casting mold by a method wherein the slip casting mold is made of aggregate consisting of ceramic powder and water soluble polymer. CONSTITUTION:As aggregate, ceramic powder made of silicon nitride or the like is exampled. When ceramic powder made of the same material as that of the ceramic to be cast is employed, formed body can be prevented from being polluted with mold material. The preferable average particle diameter of the aggregate is 10mum or less. As the water soluble polymer, polyolefin glycol and the like are exampled. The preferable maximum mixing weight ratio of the polymer to the aggregate is 30:70. The casting mold concerned can be produced by pouring the mixture of the aggregate and the water soluble polymer through water in a gypsum mold or the like and, after being dried, releasing the dried mixture from the gypsum mold or by cold-isostatic-pressing the mixture of the aggregate and the water soluble polymer with a CIP forming device.
