Title: Fuel injection pump for internal combustion engine
Inventor: YAMAGUCHI HIROSHI
IPC: F02M59/44
Filed: 1978-02-03
Abstract: PURPOSE: To provide a fuel injection pump for an internal combustion engine in which the speed  of a delivery valve is decreased at the end of a descending motion thereof to thereby reduce  production of noises and is increased at the beginning of a descending motion of thereof to thereby ensure its sucking-back effect by constituting the pump such that a cam for control of the  valve has an appropriate profile which provides such motion of the valve.   
     CONSTITUTION: When a cam 10 is rotated in a counterclockwise direction to raise a plunger 2,  a recessed section 1a of the plunger 2 passes by an inlet/outlet hole 5 so that pressure in a  chamber 6 is raised and soon exceeds the force of a spring 3 whereupon a delivery valve 4 is  raised to thereby effect discharge of fuel. When the plunger 2 begins its descending motion upon  a continued rotation of the cam 10, the plunger 2 and the delivery valve 4 are first permitted to  rapidly descend due to a steep declination b of the cam 10 thereby to effect an assured sacking- back operation. At the end of a descending motion, the descending speed of the plunger 2 is  moderated due to a moderate declination c of the cam 10. After the recessed section 1a of the  plunger 2 is displaced below the inlet/outlet hole 5, fuel is sucked in. Feed of fuel is thus effected  repetitively in such a sequence of operations as described above.

Thus, a novel coagulant having a large coagulation effect can be easily produced with a simple operation without a trouble of gelation.

Title: Magnetic memory
Inventor: AIKAWA TAKASHI
IPC: G11B20/10
Filed: 1984-01-25
Abstract: PURPOSE:To increase the amplitude margin of a gate signal detecting circuit by amplifying nonlinearly a read analog signal. CONSTITUTION:As shown in figure (a), a nonlinear circuit 6 consists of diodes 7 and 8 and a resistance 9 and amplifies an input signal A by means of the nonlinear characteristics of diodes 7 and 8 with the amplification factor of figure (b). In other words, no current flows to both diodes 7 and 8 before the voltage of about 0.6V is applied forward. Then the voltage is produced at the output side. Therefore no voltage is virtually produced at an input part of a gate signal detecting circuit 4 when the read signal has a low level as long as the voltage is previously set at <=0.6V at a part where no read waveform is needed, i.e., a place near a base line of a low density part. While the amplification factor is increased as the level of the read signal rises up, and a peak signal is delivered with a high level. Thus it is possible to increase the setting range of a slice level SL of the circuit 4 up to about the base line. Therefore the amplitude margin can be increased enough.

Title: Multi-strain quantum well semiconductor laser

IPC: H01S5/00
Filed: 1993-01-28
Abstract: PURPOSE:To provide a laser having a low threshold by preventing the occurrence of nonuniformity both in strain and injected carrier between wells. CONSTITUTION:The free-standing lattice constants of all multi-strain quantum wells are made coincident with the lattice constant of a substrate by adding a strain which is opposite to that applied to a well layer 11 to a barrier layer 12. Therefore, the occurrence of nonuniformity both in strain and injected carrier between wells is prevented and the threshold current of a multi-strain quantum well laser can be remarkably reduced.
