Title: Automatic fire extinguisher
Inventor: KAWAKAMI SUSUMU
IPC: A62C37/44
Filed: 1990-09-28
Abstract: PURPOSE:To limit the injection of a fire extinguisher only to the origin of a fire and quickly extinguish the fire by operating a directional sensor for detecting the radiating strength of ultraviolet to infrared rays and a fire extinguisher injecting nozzle parallel thereto so as to regularly change their directions within a specified three-dimensional angle at the same time, and releasing a nozzle valve in a position in which the sensor outputs a fixed level or more. CONSTITUTION:A directional detecting sensor 1 for detecting the radiating strength of ultraviolet to infrared area wavelengths, a fire extinguisher injecting nozzle 2 having an axis parallel to the axis of the sensor, and a control system 3 for operating the both to regularly change their directions over the whole circumference within a range from the inclined direction of about 15 deg. to nearly the horizontal direction to the vertical downward direction at the same time, fixing the axial direction of the nozzle 2 in the position in which the detecting sensor 1 outputs a fixed level or more, and opening a valve 4 are provided. Thus, when the radiation of infrared rays by a fire is detected during oscillation of the sensor 1 and the directional change by rotating operation, the nozzle 2 is fixed in the fire direction by the control system 3, the valve 4 is opened, so that the fire extinguisher can be collectively injected in the fire direction for fire extinguishment.

Title: Single-lever type mixing faucet
Inventor: TAKAGI SHIGERU
IPC: E03C1/042
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To improve operability by providing an operation lever at the tip section of a discharge pipe, automatically rotating the operation lever relatively to the discharge pipe when the discharge pipe is rotated, and holding and controlling the direction of the operation lever to the fixed direction set in advance. SOLUTION: When a discharge pipe 14 is located at the position O protruded forward toward a user, an operation lever 30 is protruded forward toward the user at the tip section of the discharge pipe 14. When the discharge pipe 14 is rotated CCW to the position R, the operation lever 30 is automatically rotated in the opposite direction by the same angle relatively to the discharge pipe 14, and the operation lever 30 is kept at the state protruded forward. Although the operation lever 30 is provided at the tip section of the rotating discharge pipe 14, the operation lever 30 is invariably kept at the state protruded forward even when the discharge pipe 14 is rotated to the right or left, thus the operability when a faucet is used can be improved.

Title: Zn-br battery
Inventor: TANGE KYOICHI
IPC: H01M12/08
Filed: 1987-10-15
Abstract: PURPOSE:To enhance the battery efficiency by allowing electrolyte to contain complex agent, zinc bromide, and a specific zinc salt, and thereby suppressing the amount of self-discharging. CONSTITUTION:Electrolyte consists of a water solution containing zinc bromide and certain zinc salts, which contain as neg. ions at least one of the NO, SO, SiF, CN<->, BF. The amount of self-discharging of battery is proportional to bromine concentration dissolved in positive electrode liquid except complex, but zinc bromide is added in an amount more than necessary for charging in order to prevent eccentricity of Zn ions in the electrolyte toward the pos. electrode liquid during normal charging and shortage of Zn ions in the neg. electrode liquid in the latest period of charging. Thus a large quantity of bromine ions are contained, so that complex ions with bromine are easily formed to cause increase of the amount of self-discharging. If therefore NO<-> and/or SO which lessens the free Br2 concentration is contained instead of Br<-> as zinc salt, the free Br2 concentration can be suppressed while lacking Zn<++> in the latest period of charging is compensated. This enhances the battery efficiency.

Title: Error correction circuit, electronic device and error pointer output method
Inventor: TANAKA TARO
IPC: G11B20/18
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To shorten a time required for an output of an error pointer by decreasing number of times of access to a pointer memory. SOLUTION: A C1 decoding means 112 conducts error correction to form an error pointer P1 indicating a state of an error every one frame, a C2 decoding means 114 conducts error correction by taking a state of the P1 into account to form an error pointer P2 indicating a state of an error every one frame and outputs the data after conducting error correction and an error pointer P to a poststage. In this case, when the C2 decoding means 114 discriminates that no error is in all symbols of one outputted frame, or when the C2 decoding means 114 discriminates that there is possibility of an error in any symbol of one outputted frame and can not specify whether or not an error is in any symbol, the error pointer P is outputted without reading out the error pointer P1 from a pointer RAM 124.

Filed: 1985-11-22
Abstract: PURPOSE:To prevent excessive feed of fuel when decelerating by providing a selector valve for passages on the upper and lower courses of a supercharger, on a pressure passage to a secondary pressure reducing chamber in an engine with a supercharger using a gaseous fuel, and introducing pressure on the upper course side when said engine is decelerating. CONSTITUTION:The pressure of a gaseous fuel such as an LPG which is fed into an engine 1 with a supercharger 10, is reduced to a defined value in a primary pressure reducing chamber 24, and rendered a pressure corresponding to the pressure of a control pressure chamber 36 in a secondary pressure reducing chamber 31, to be fed from a pipe 41 into a Venturi 11. Either of pressure in a pressure passage 45 on the lower course of the supercharger 10 or pressure in a pressure passage 46 on the upper course of the supercharger 10, is introduced into the control pressure chamber 36 via a selector valve 44. In the normal operation, pressure in the lower course side pressure passage 45 is used, regulating fuel pressure in accordance with the supercharged pressure. When decelerating, the pressure in the upper course side pressure passage 46 which is nearly equal to the atmospheric pressure is used by shifting the selector valve 44, while a solenoid valve 42 is closed to cut off fuel. Thereby, at the time of the following acceleration, excessive feed of fuel will not take place due to the reduced fuel pressure.
