Title: On-vehicle air cleaning device
Inventor: UCHIDA GORO
IPC: B60H1/24
Filed: 1984-07-23
Abstract: PURPOSE:To increae the efficiency of an air cleaner while the air cleaner automatically controls its start-up and shut-down in response to the output of a smoke detector by controlling the number of revolution of the air cleaner in response to the smoke intensity. CONSTITUTION:An automatic control circuit 1 consists of a smoke detector 2 which senses light scattered by smoke particles in air while a light emitting diode emits light intermittently, a level reader 3, and an output unit 4. This automatic control circuit 1 is installed around a room lamp 12 on the ceiling of a car and controls the output unit 4 in starting up and shutting down a fan motor 7 of an air cleaner 5 fitted in a rear package tray 11. The level reader 3 determines the output voltage of the smoke detector 2 in response to the smoke intensity by comparing the output with the threshold value which is set into numbers of steps in advance so as to output the voltage in response to the smoke intensity. Thus, the number of revolution of the motor 7 is increased as the smoke intensity increases.

Title: Method and device for fuel combustion in internal combustion engine
Inventor: YAMAMOTO KAZUNORI
IPC: F02M25/022
Filed: 1995-05-27
Abstract: PURPOSE: To increase the output torque by injecting a water heated over the carburetion point into a cylinder chamber immediately before the start of each combustion stroke in an internal combustion engine, producing water vapor, and making good use of the energy of evaporative expansion. CONSTITUTION: When an internal combustion engine is in operation, gasified fuel is introduced to a cylinder chamber 2 from an air supply pipe 5, compressed by a piston 3, ignited by an ignition plug 7, and exhausted from an exhaust pipe 6. Immediately before the gasified fuel is ignited upon being compressed in the cylinder chamber 2, the water in a tank 10 is passed through a heating/ pressurizing device 11 and injected into the cylinder chamber 2 from an injection nozzle 8 using a pump 12. At the same time as combustion of the gasified fuel, the water is evaporated and left expanding together with the fuel, which leads to an increase in the output torque of the piston-cylinder device 1.

Title: Channel access method for cordless telephone set
Inventor: ISHII YOSHITOMO
IPC: H04B7/26
Filed: 1993-05-31
Abstract: PURPOSE:To prevent the generation of impropriety such as tapping by updating a channel number position everytime when entering the battery saving when the line shifts from a radio connection state to a waiting state. CONSTITUTION:When speech end processing is ended and the waiting state is started, a battery save position channel number is read out from a memory for pointer. When a speech request comes during the battery save off period, a dead channel is retrieved from the latest dead channel information at the time of turning off and the radio connection state is started. On the other hand, when a speech request comes during the battery save on period, the dead channel is retrieved from the channel number written in the memory for point in the preceding processing and the radio connection state is started. As the result, the state that the specific channel is concentrically busy can be avoided. That is, different channels are retrieved every time if the retrieval is started from the latest dead channel and the possibility of using the same channel becomes low and tapping can be prevented.

IPC: H01L21/302
Filed: 1991-05-28
Abstract: PURPOSE:To uniformly etch thin film, such as spontaneous oxide film, on a wafer. CONSTITUTION:First and second storage tanks 2 and 4 for etchant are provided under a process bath 1. An etchant containing 50% hydrofluoric acid and pure water is introduced to the second storage tank 4, and it is circulated between the two storage tanks through a supply pipe 41 and a return pipe 42 by a pump P1, so that the hydrofluoric acid is mixed uniformly.

Title: Level meter for liquid refrigerant
Inventor: ONOE TATSUYA
IPC: G01F23/26
Filed: 1988-06-21
Abstract: PURPOSE:To perform highly sensible liquid level detection with a simple structure by providing a bar-like superconductive substance showing a superconductive state at a temperature lower than that of a liquid refrigerant. CONSTITUTION:The part of a bar-like superconductive substance 6 below a liquid surface 1a is in a superconductive state and has perfect diamagnetic characteristics, but the part of the substance 6 above the surface 1a is in a normal conductive state and does not have the diamagnetic characteristics. While a magnetic field is impressed upon the substance 6 from the outside, the magnetic field cannot get into the substance below the liquid surface 1a, because of the perfect diamagnetic characteristics. Therefore, the output of a magnetic field measuring element 7 provided to the part is zero. On the other hand, part of the magnetic field gets into the substance 6 above the liquid surface 1a, because the substance 6 does not have the perfect diamagnetic characteristics, and a fixed output is obtained from the magnetic measuring element 7 to the part. Therefore, the point at which the output of the element 7 changes from zero to the fixed value is detected as the liquid surface by means of a detector. Thus highly sensible liquid level detection can be realized with a simple structure.
