Abstract: PROBLEM TO BE SOLVED: To increase sealability, prevent detect in cutoff of water, and reduce operation torque, by comprising a packing guide having wedge projections and a packing so that the wedge projections are formed valve openings for hot water/cold water and a valve opening for mixed water. SOLUTION: Whole valve openings 3a, 3b for hot water and water get pressure when feed hot water/cold water pressure is applied. Packing 8 has wedge recesses 6a to enable to prevent force of drawing the packing 8 on a side of a valve opening 3c for mixed water. That is, tips of wedge projections 6a of a packing guide 6 are disposed inside an inner diameter of the packing 8 to receive pressure P applied to the packing 8, resulting in preventing the force of drawing the packing 8 on the side of the valve opening 3c for the mixed water from a side of the valve openings 3a, 3b for the hot water and the cold water. Accordingly, shortage of interference is eliminated to enable to restrain defect in cutoff of the water. The packing guide 6 can tightly fix the packing 8 to enable to reduce the interference thereby to reduce operation torque.

IPC: F16K1/34
Filed: 1989-02-09
Abstract: PURPOSE:To prevent leak of gas and bad influence to a product in a valve device wherein a valve is operated pneumatically by providing a plutality of seal faces which open and close of a flow passage. CONSTITUTION:When air is introduced from an air inlet port, the air enters all air chamber 2, operate a valve 6 connected to a piston 7 in a direction of an arrow a, and entirely opens a passage 4.

Seal faces 10a, 10b of a valve seat on which the valves 6, 6a are set are doubly constructed. In case that dust or the like is attached to one of the seal faces 10a and 10b, the airtightness is maintained by the combination of the other of the faces and the valve 6a or 6 to perfectly stop the flow of gas. It is therefore possible to prevent the gas from leaking from the passage 4 and suppress bad influence to products.

IPC: G01J3/443
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To accurately measure an amount of a pulse light by accurately estimating an average value of number of photoelectrons emitted from a photoelectric conversion surface of a photodetector. SOLUTION: When a luminous flux to be measured is incident to a photodetector 10, photoelectrons are emitted, multiplied, and a current signal is output. This signal is set to a voltage signal by an integrating means having a charge sensitive preamplifier 20 and a waveform shaping amplifier 30. A peak value of the signal is output from a peak holding circuit 40 only during a period of the state that the integrating means is nonsaturated, converted into a digital value by an A-D converter 50, and a crest distribution n (h) of the voltage signal is generated by a histomemory 60.  A number distribution of the photoelectrons emitted from the photodetector 10 upon inputting of the flux to the photodetector 10 is estimated based on the distribution n (h), single photoelectron event crest distribution and k-photoelectron event crest distribution (k=1, 2, 3,...), and further an amount of the flux is obtained.

Title: Magnetic rotation sensor
Inventor: TAMURA KATSUYOSHI
IPC: G01D5/14
Filed: 1983-02-28
Abstract: PURPOSE:To obtain a rotation sensor which has a large gap between a rotation part and a magneto-resistance element and superior characteristics and reliability by installing the magneto-resistance element which detects signal magnetic field variation as resistance variation on a substrate made of a ferromagnetic material. CONSTITUTION:When there is no ferromagnetic body near a magnet for generating a signal magnetic field, the signal magnetic field becomes weak abruptly according to the distance from the magnet, but when there is a thick ferromagnetic material plate near the magnet, the reactance of the internal magnetic path in this plate is extremely small, so the magnetic field reaching this plate is relatively intense. Therefore, the magneto-resistance element is installed on the substrate made of the ferromagnetic material. Consequently, a large gap is left between the rotation part which generates the signal magnetic field and the magneto-resistance element and the allowable tolerance of parts and assembly increases to obtain a highly reliable product easily.

Abstract: PURPOSE:To reduce an electrostatic capacitance so as to obtain a photodetector of a high speed response by a method wherein a p-type and an n-type semiconductor layers are arranged in parallel with each other on an insulating substrate and the p-type and the n-type semiconductor are connected with each other through a narrow bridge-like connecting part, where the connecting part comprises a p-n junction and a depletion layer. CONSTITUTION:An n<-> InGaAs layer 12 and a p<+> InGaAs layer 13 are formed on an insulating InP substrate 11, where a narrow bridge-like part connecting the n<-> InGaAs layer 12 with the p<+> InGaAs layer 13 forms a p-n junction 16. A p-side electrode 14 and an n-side electrode 15 to be bonding pads are constructed on the n<-> InGaAs layer and the p<+> InGaAs layer 13 respectively. A photodetector is formed as mentioned above, where the p-n junction 16 and a depletion layer 17, which spreads wide when an reverse bias is impressed on the p-n junction 16, exist only in a narrow bridge-like connecting section 18. Therefore, the electrostatic capacitance is determined depending on the width and the thickness of the connecting section 18, so that a required high speed property can be obtained by varying the connecting section 18 in shape and size if necessary. By these processes, the connecting section 18 can be reduced in an electrostatic capacitance so as to improve the photodetector in a high speed response property.

Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To feed a large amount of a material to be crushed timely into a compressor and to perform compression work efficiently by controlling the number of revolution of the cutters of a crusher by making it variable. SOLUTION: A lifting transportation conveyer 2 is installed on the outlet side of a crusher 1 for crushing refuse, etc., by the engagement of cutters. A crushed material 3 of refuse, etc., is mounted on the conveyer 2 and fed into a compressor 5 which works by the forward/backward movement of a press cylinder through a feed member 4 placed at the upper end of the conveyer 2. Since the conveyer 2 is moving always at a constant speed, when the press cylinder is stopped, the rotation speed of the cutters of the crusher 1 is increased, and a large amount of the material 3 is mounted on the conveyer 2. When the press cylinder retreats after a compression process, the rotation speed of the cutters of the crusher 1 is decreased, and the amount of the material mounted on the conveyer 2 is reduced.
