    • The present invention enables the manufacture of a trochoid pump having a crescent which has been considered theoretically impossible, by employing an inner rotor of a trochoid pump. An inner rotor having a predetermined number N of teeth that is equal to or larger than 4 is formed in advance. In order to manufacture an outer rotor with a predetermined number (N plus a natural number equal to or larger than 2) of teeth, row circles of a diameter slightly smaller than that of a drawn circle are disposed so as to bring the row circles into contact with the tooth bottomland of the inner rotor tooth profile, the inner rotor tooth profile is rotated by half a tooth about the center of the inner rotor and the outer rotor tooth profile is also rotated by half a tooth of the predetermined number (N plus a natural number equal to or larger than 2) of teeth about a virtual center of the outer rotor including the row circles, an established center is determined from the virtual center or the like at the time at which the contact state is assumed, a reference circle is drawn that has a radius from the established center to the row circles and that has the total predetermined number (N plus a natural number equal to or larger than 2) of the equidistantly spaced row circles to form the row circles as outer rotor tooth tips, thereby manufacturing the outer rotor tooth profile.
    • 本发明能够通过使用次摆线泵的内转子来制造具有理论上不可能理解的具有月牙的次摆线泵。 预先形成具有等于或大于4的预定数量N个齿的内转子。 为了制造具有预定数量(N加上等于或大于2的自然数)的齿的外转子,布置直径稍小于拉圆的直径的行圆,以使行圆圈 与内转子齿廓的齿底接触,内转子齿廓绕内转子的中心旋转半个齿,外转子齿廓也旋转预定数量的半齿(N加 围绕包括行圆的外转子的虚拟中心的等于或大于2的齿的自然数,在假定接触状态时从虚拟中心等确定建立的中心,参考 绘制圆,其具有从建立的中心到行圆的半径,并且具有等距离间隔的行圆的总预定数(N加上等于或大于2的自然数),以形成ro w为外转子齿尖,由此制造外转子齿廓。

    • It is made possible to control RAMs of a plurality of kinds differing in control system by using a single memory controller (LSI). A memory control circuit having an LSI configuration receives a RAM access request signal, which does not depend on a classification of a RAM device, from a high rank control unit such as a CPU (not shown), and transmits a RAM control signal & data group to a subordinate RAM device to control it. Upon receiving the RAM access request signal, the memory access RAM busy management circuit generates RAM control command & data suitable for the currently connected RAM device, and transmits it to the memory access common control circuit. Upon receiving the RAM control command & data, the memory access common control circuit generates RAM control signal & data group and transmits it to the RAM device.
    • 通过使用单个存储器控制器(LSI),可以控制控制系统的不同种类的RAM。 具有LSI配置的存储器控​​制电路从诸如CPU(未示出)的高等级控制单元接收不依赖于RAM设备的分类的RAM访问请求信号,并且发送RAM控制信号和数据 组合到一个从属RAM设备来控制它。 在接收到RAM访问请求信号时,存储器存取RAM忙管理电路产生适用于当前连接的RAM设备的RAM控制命令和数据,并将其发送到存储器存取通用控制电路。 存储器访问共用控制电路接收到RAM控制命令和数据后,生成RAM控制信号和数据组,并将其发送到RAM装置。

    • The invention has: a housing; a pump section formed of a drive gear unit and a driven gear unit; a main flow channel through which oil pressure is applied to the driven gear unit in a discharge volume reduction direction; a first branching flow channel through which oil pressure that assists oil pressure from the main flow channel is applied; a second branching flow channel through which oil pressure is applied to the driven gear unit in a discharge increase direction; a first flow channel control section; a second flow channel control section; and a spring that elastically urges the driven gear unit in a discharge increase direction. The first flow channel control section and the second flow channel control section can perform switching control in accordance with each increase or decrease of engine revolutions and in pressure.
