Patent JP-H0477268-A (JP)
Title: Thermal head
Inventor: KATO YOSHIMASA
IPC: B41J2/335
Filed: 1990-07-18
Abstract: PURPOSE:To make a pressure applied to a cylindrical platen at a serial printer uniform and thereby improve print quality by forming a section with an arc recessed part in the longitudinal direction of a thermal resistor array on the surface of a substrate with a glazed layer. CONSTITUTION:A glazed layer 2 is formed on a recessed aro-like carved area 15 by grinding an area corresponding to a thermal resistor array of a ceramic insulating substrate 1. After the formation of the substrate, a Ta SiO2 resistor layer and an Al conductor layer are attached by a sputtering technique, then thermal resistors 3 and conductor wiring 4 are patterned using exposure and etching techniques and finally a protecting film 5 is formed excepting an electrode part of an external lead wire. Thus it is possible to enable a thermal head to come in contact with a cylindrical platen positively and softly. Therefore, print quality is improved and printing speed is accelerated or a large-size character is printed as the thermal resistor array can be made long.

Title: Polarization measurement method and apparatus
Inventor: AAMETSUDO SHIYAMIN SHITSUDEKI
IPC: G01J4/04
Filed: 1989-07-21
Abstract: PURPOSE: To perform static and dynamic measurements easily, automatically and inexpensively by passing a collimate beam through a beam expander and then through four individual Stokes filters. CONSTITUTION: In a method for measuring the polarized state of collimated beat of an incoming electromagnetic radiation, the beam is passed through beam expanders 13, 14 to create an enlarged collimate beam 15 having diameter larger than that of the incoming collimate beam and then a plurality of parts of enlarged beam are passed simultaneously through four different Stokes filters F1, F2, F3, F4. After respective split beam parts have passed through corresponding Stokes filters, intensity is measured for respective beam parts 21, 22, 23, 24 and analyzed thus determining the polarized state of incoming beam.

Filed: 1982-10-28
Abstract: PURPOSE:To suppress the formation of by-products and obtain the aimed compound in high yield in preparing allyl alcohol from allyl chloride in the presence of a cuprous compound as a catalyst, by hydrolyzing the above-mentioned raw material with steam in the vapor phase. CONSTITUTION:Allyl chloride as a raw material is hydrolyzed with steam in the vapor phase in the presence of a catalyst obtained by supporting a cuprous compound, e.g. a cuprous halide, cuprous oxide, cuprous cyanide or cuprous acetate, on a carrier to give the aimed compound in high yield. Preferably, the reaction temperature is 105-150 deg.C, and the molar ratio between the raw material and the water is (1:7)-15. The residence time of the raw material is preferably 1.5- 20sec. The formation of by-products is little without contaminating the reaction product with the catalyst by the above-mentioned method. The chlorine in the raw material can be easily recovered as hydrogen chloride, and this method is very advantageous industrially.

Title: Hydraulic control unit having shuttle valve
Inventor: SHIBAYAMA NAOSHI
IPC: F16K15/04
Filed: 1983-10-14
Abstract: PURPOSE:To ensure the operation of a ball even if oil is supplied through other shuttle valves, by making the bore of an inlet port of a first shuttle valve smaller than the bore of an inlet port of a second shuttle valve. CONSTITUTION:The bores of inlet ports 10a, 10b of a first shuttle valve 10 are smaller than the bores of inlet ports 12a, 12b of a second shuttle valve 12. Thus, since relatively large negative pressure acts on the ball 32 even if oil amount is small, the ball 32 is securely operated even when oil is supplied through the other shuttle valves.

Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor memory operating at a high speed by reducing a margin in the case of designing a timing of an internal control signal. SOLUTION: A dummy address decoder 13 operating equivalently to an address decoder 3 is provided. In the case of generating a one shot pulse in an address transition detector 14, the detector 14 sets a leading edge of the one shot pulse in response to a change of an external address input to an address buffer 2, the decoder 13 detects a time point of establishing an output of the decoder 13 according to a trailing edge of the pulse, and is set according to the time point. Thus, a width of the one shot pulse generated from the detector 14 is set to an optimum state according to the operating state of the decoder 3.

Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a new type of method and device for detecting fire with which a fire is detected with high sensitivity at an initial fire stage of smoking or non-flame burning. SOLUTION: A sensor device installed in a certain area (i) detects a gas and discriminates the gas while using an existing pattern recognition method such as main component analysis (S1-S4). When no gas is detected, a flag fi is turned to '0'. When the gas is discriminated and it shows humidity, the state of fi=1 is established. When it is not humidity, the state of fi=0 is provided (S4-S7). Thus, N areas are monitored (S8 and S9), J=f1+f2+...+fN is calculated (S10), and in the case of 0<J<N (S11), it is determined the area of fi=1 has a high possibility of a fire (S12). At the time of J=0 or J=N, no gas is detected, on any gas such as alcohol other than the humidity is detected, or because of high possibility of an ordinary humidity change, non-fire is judged (S13).

Title: Electronic control type fuel injector for internal- combustion engine
Inventor: OKAMOTO OKIMICHI
IPC: F02D41/34
Filed: 1982-11-02
Abstract: PURPOSE:To permit the pulse width-flow-rate characteristic of a fuel 1 injection valve to be controlled by the control within a specific narrow range by making constant the pulse width of the pulse for driving the fuel injection valve and making the number of pulses per time proportional to the amount of air inhaled. CONSTITUTION:The output terminal of an air flow meter 11 is connected to an integrator 13. The output terminal of a comparator 14 is connected to the reset terminal of the integrator 13 and further connected to a monostable circuit 15. The output of the comparator 14 forms the signal having the frequency proportional to the amount of air inhaled. Thus monostable circuit 15 is triggered by said signal. Therefore, the amount of fuel corresponding to the amount of air inhaled is obtained by making the number of injetion per time proportional to the amount of air inhaled. Thus, fuel injection can be controlled accurately with simple constitution.

In a denitrifying apparatus 3, the water is irradiated with short wavelength light such as UV on a catalyst under reducing conditions, electric current is supplied between electrodes and electromagnetic field conversion is carried out to excite and react the nitrate ions and hydrogen atoms and the nitrate ions are reduced and discharged as gaseous nitrogen into the air.  The water freed of nitrate nitrogen is sent to a treated water oxidation acclimation apparatus 4, where oxygen is blown into the water in the reduced state to convert and acclimate to an oxidized state. In this way, the nitrate nitrogen included in underground water, or the like, is removed.
