Filed: 1980-02-29
Abstract: PURPOSE:To increase the converging speed and the stability after convergence with no increment of the hard quantity for an FIA-type automatic equalizer, by controlling the amount of an integration in accordance with the size of the error signal. CONSTITUTION:The error signal ek delivered from the subtractor 5 is identified by the identifier 21 and then catches the code to produce sgnek. The delay line 6 with tap produces the signals sgnrk-N-sgnrkn, and these signals are multiplied by the signal sgnek at the multipliers 7-n...70...7N to produce the signal that shows a code (+ or -or o). On the other hand, the error signal ek is converted into a pulse duration signal through the level/pulse duration converting circuit 22. This pulse duration signal is applied to the AND circuit 230 and the NAND circuit 240 that are shown as the examples for the tap O, and then varies the width of the output signal of the multiplier 70. An integrator consisting of the diodes 250 and 260, the resistance 270, the amplifier 280 and the capacitor 290, each is actuated by the positive output pulse of the circuit 230 and the negative output pulse of the circuit 240.

Title: Fuel-injection pump
Inventor: YOSHIMURA NOZOMI
IPC: F02M59/26
Filed: 1984-02-16
Abstract: PURPOSE:To prevent the occurrence of space or erosion due to a cavitation inside a high pressure pipe as a sudden outflow of fuel is slowed down, by installing one step of a minute opening part of a fine groove at the end of plunger's ramming motion. CONSTITUTION:A plunger 1 to be connected to a reciprocating roller guide 3 performs an up-and-down motion, serving as a fuel-injection pump. Fuel flows in an oil feed chamber 2A by way of a main pipe 8 and then a branch pipe 7, and when the plunger goes down, the fuel enters inside a barrel from a hole (d) of a plunger barrel 2 and rammed by the plunger 1, coming into high pressure in consequence, then sprayed to the inside of a cylinder from a fuel valve 10 after passing through from a pump cover 6 to a high pressure pipe 9. When the plunger 1 moves upward, the hole (d) closes at an effective ramming part (a), thus fuel inside the barrel (e) becomes high pressure. Motion of the ramming part (a) is over, the hole (d) of the barrel opens a little by means of a minute open part (b) of a fine groove, then the barrel's hole (d) comes into a state of being fully opened by a full-open part (c). Therefore, a sudden outflow of fuel is eased to slow enough, thus the said phenomenon may in no case occur.

Filed: 1987-02-09
Abstract: PURPOSE:To measure a flexible material like a printed board without spoiling its quantity of deformation by structuring a detector so that both side points are contact reference terminals and one center point is a noncontact type displacement detection system. CONSTITUTION:The reference contact terminal 5 are provided to both ends of a variable length detector fitting table 2 and an optical sensor 3 is fitted at its center part. The quantity of displacement of a measurement point is detected by the sensor 3 and data is processed by using a microcomputer.
