Title: Adjusting device of injection timing of distribution type fuel injection pump
Inventor: KAWAGOE MICHIO
IPC: F02D1/18
Filed: 1980-08-29
Abstract: PURPOSE: To reduce HC content in exhaust gas with excellent responsibility by a method wherein when fuel pressure rises suddenly suck a by path means is provided that the fuel pressure can act directly on a timer piston according to this pressure change.  
     CONSTITUTION: Such a bypath device 35 composed of a valve chamber 35a and the like is provided that when the fuel pressure rises suddenly it can act directly on a timer piston according to this pressure change. By means of the quick acceleration of the engine the number of rotation, therefore, the discharge pressure also of a vane pump 33 rises quickly and is transmitted instantly to the 1st pressure chamber 35c of the device 35. However, since the discharge pressure is transmitted later to the 2nd pressure chamber 35e through a throttle 38 installed on a passage 39, a pressure difference occurs between these two chambers 35c, 35e and a valve body 35b connected to a diaphragm 35d bent by this pressure difference opens a passage 36. Thereby, the fuel pressure transmitted to the pressure chamber 35e is transmitted from the passage 36 to a timer chamber 23 earlier than through a passage 22 and the piston 16 takes an injection timing earlier than when there is provided an orifice 21 only.

IPC: H05K1/18
Filed: 1993-05-20
Abstract: PURPOSE:To make it possible to reduce stress exerted on electronic parts due to camber in a circuit board on which the parts are mounted, and thus prevent cracking of the parts. CONSTITUTION:External electrodes 2 and 3 are formed on both ends of the mounting face of an electronic part 1a; at least one of the electrodes is extended toward the center of the part, and the electrodes 2 and 3 are insulated from each other.

IPC: H04N5/783
Filed: 1983-06-30
Abstract: PURPOSE:To prevent a mechanical oscillation in a bimorph by shaping a saw tooth wave deflecting voltage so that it has a gentle amplitude characteristic in the period when the amplitude characteristic of the deflecting voltage is changed rapidly. CONSTITUTION:Integral characteristics 6 and 7 are changed in accordance with the frequency of the control pulse from a control pulse generator 5, and integrators integrate hardly a voltage when the control pulse is >=300kHz. A switching pulse (a) or (b) is inputted to a terminal 10. Monostable multivibrators 15 and 16 output pulses (i) and (j) corresponding to periods when the amplitude of the saw tooth wave deflecting voltage is changed rapidly. The control pulse generator 5 outputs control pulses (a) and (b) having frequencies 1kHz and 500kHz from terminals A and B. Both pulses are selected alternately by switches 31 and 34 and are given to the integrator 6. They are given to the integrator 7 also similarly. Consequently, saw tooth deflecting voltage (d) and (c) are integrated in periods of pulses (i) and (j) by said characteristics of integrators, and integral outputs (m) and (k) are taken out from integrators. An error output from a tracking control circuit 4 is superposed onto integral outputs (m) and (k), and they are given to a pair of bimorph plates.

IPC: E04C3/34
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To reduce weight by forming a zone wider than an opening in a corrugated recess of a backing corrugated steel plate for a precast concrete slab. SOLUTION: One side face of a precast concrete slab 11 is backed with a corrugated steel plate with wire nets 13a, 13b welded to both faces. The concrete slab 11 and the steel plate 12 are integrally unified to constitute a form 10. The steel plate 12 has a corrugated shape that protrusions and recessions are alternately and continuously connected. The cross sectional shape of the recess is formed to have such a trapezoidal shape that the width of the deepest part of the corrugated recess is larger than the width of the opening. Then, concrete is formed on a condition that concrete is caught by the recess of the steel plate 12 in the form 10. Since the concrete slab 11 is further unified with the steel plate and the recessed depth of the steel plate 12 can be minimized, it is possible to reduce the thickness of the form 10.  In this way, the thickness and of weight of the precast concrete form can be reduced and further, the flexural rigidity of the form can be improved.

Title: Light-triggered thyristor
Inventor: KISHI KEIJI
IPC: H03K17/78
Filed: 1978-09-27
Abstract: PURPOSE: To efficiently and stably turn on a light-triggered thyristor, by making the output level of light signal from a first light emitter variable by a light signal from a second light emitter which is caused to emit light by the turn-on of the thyristor.  
     CONSTITUTION: A light emission control circuit 1 comprises a transistor 12 and a phototransistor 21. A first light-emitting diode 2 is energized to emit light, which is supplied to a light-triggered thyristor 4 through a first light guide 3 to turn on the thyristor to supply an output to a load 5 and energize a second light-emitting diode to emit light. This light is supplied to the phototransistor 21 of the light emission control circuit 1 through a second light guide 9. As a result, the output time of light signal from the first light-emitting diode 2 can be shortened to reduce the decrease in its lifetime. Even if the output level of the diode 2 falls, the thyristor can be surely turned on.

Title: Data holding circuit and buffer circuit
Inventor: UEDA KIMIHIRO
IPC: H03K19/00
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a data holding circuit which needs a small area and the small power consumption and has high reliability. SOLUTION: The output terminals DO and DOB are connected to the input terminals DI and DIB where the signals of potentials VDD (GND) of H and L levels are exclusively inputted with each other via the transistors TR MN2 and MN1 and the inverters INV1 and INV2 respectively. The input terminals of the INV1 and INV2 are connected to a power supply VDD via the TR MP2 and MP1 whose gates are connected to the output terminals of the INV1 and INV2 respectively. The potentials of signals which are inputted to the INV1 and INV2 are dropped by the threshold voltage by the TR MN2 and MN1 respectively. Then one of TR MP1 and MP2 whose control terminal receives input of an L-level signal applies the potential VDD to the input terminal of one of both INV1 and INV2 that should output an L-level signal. Thus, the voltage drop is compensated by an amount equal to the threshold voltage.
