Title: Fuel injection device for internal combustion engine
Inventor: OMORI TOSHIHIKO
IPC: F02M51/00
Filed: 1989-03-03
Abstract: PURPOSE:To prevent the drop of a plunger and a follower by coupling a ring in a notch peripheral groove formed on the inner periphery of the follower guide of an injector body, end freely inserting a spring on the outer periphery of the follower guide. CONSTITUTION:A ring 30 is coupled in a notch peripheral groove formed on the inner periphery of the follower guide 25 of an injector body 15. A compression return spring 28 is freely inserted on the outer periphery of the follower guide 25. When a follower 17 is thrust in the axial direction of the follower guide 25, the ring 30 is slid on taper faces 21 and 22 provided on the outer periphery of the follower 17 and coupled with a notch long groove 20, thus the assembling of a plunger 16 and the follower is completed.

Title: Reduction gear
Inventor: FUJINO SHOJI
IPC: F16H1/28
Filed: 1987-03-07
Abstract: PURPOSE:To make it possible to get high reduction gear ratio, by increasing or decreasing the number of teeth of a profile shifted spur gear wheel compared with the number of teeth of spur gear wheel, in reduction mechanism, for making it possible to change the output rotation direction as being the same with the input rotating direction, or being opposite to it. CONSTITUTION:This reduction mechanism is constituted by setting a profile shifted spur gear wheel 2, which is the same with a spur gear wheel 1 in its outside diameter and not the same in number of its teeth, in parallel with the spur gear wheel 1, and setting a spur gear wheel 3 which is engaged with said two gear wheels 1, 2 at the same time, and turns round on its own axis axis as revolving on the outer circumference of the gear wheels 1, 2. As the spur gear wheel 3 is engaged with both of the spur gear wheel 1 and the profile shifted spur gear wheel 2, which are different from each other in number of their teeth, the shifted spur gear wheel 2 is moved in the direction of an arrow for compensating the positional discrepancy of the teeth, when the spur gear wheel 3 is revolved on the outer circumference of the spur gear wheel 1. Then high reduction gear ration can be obtained by inputting the revolving speed of the spur gear wheel 3, and outputting the rotating speed of the profile profile shifted spur wheel 2.

IPC: G06F9/48
Filed: 1981-04-09
Abstract: PURPOSE:To prevent a processing of a low priority data from being kept queuing for a long time, by storing the data transfer requests given from plural  channels based on the order of priority and carrying out the processing to the  request for a low priority data after a certain period of time elapses. CONSTITUTION:The data transfer request signal given from an input/output channel CH of a computer is received by a priority control part 2. When a transfer request is produced at CH3-CH10 having high priority while the data of CH1 is transferred and held at a high priority request storing part 7 in the state of the custody, the data transfer request of the CH2 having low priority is stored in a low priority request storing part 10. When the circuit 10 turns a signal 11 showing the holding state of the request into a significant one, a low priority request forcible process control part 13 works to turn a low priority request processing state signal 15 significant in the lapse of time T. After the  time T, a high priority request processing state signal 14 is not significant any  more, and the signal 15 becomes significant to actuate a low priority request starting part 19. Thus the request is processed for the transfer of data of the  CH2 which is held at the part 13.

Abstract: PURPOSE:To process the data which is so far defined ineffective as an effective data, by using a buffer register having an (N-1)-fold length of the frame that stores the receiving data and validating the output of the stored receiving data at and after the establishment of frame synchronization. CONSTITUTION:In the case of the frame synchronizing signal where N=2, the receiving data A given from a receiver 1 is stored in a 1-frame buffer register 4, and the output receiving data B is delivered with a delay of a frame. The frame synchronizing signal D given from the receiver 1 is supplied to a shift register 5 and an OR circuit 7 in the form of a signal E having a delay of a frame. As a result, the output G of the circuit 7 is delivered as a signal which is longer than the signal D by a frame. Receiving the signal G, an AND circuit 6 feeds the reset signal F to a register 4 to reset the register. Thus the register 4 starts the stroage of the receiving data and then starts the output with a delay equivalent to the 1-frame length given to the receiving data. Then the frame synchronization is established with receiving data b and c.
