Title: Script language processor
Inventor: OTO HIDETAKA
IPC: G06F9/44
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To attain the descriptions divided into groups to eliminate the redundancy of descriptions and to reduce the code value by retrieving every method dictionary and its method name as the retrieval keys and specifying a processing function to every object to execute the function. SOLUTION: An object-oriented language program is given to an interpreter 15 which is thus started. The interpreter 15 gives a method name to a method group decision part 11 which decides whether the method is identical to a group method. If the method is identical to a group method, the interpreter 15 extracts an object, i.e., the argument of the relevant method. Then the interpreter 15 uses the extracted object as a key to specify a method dictionary and retrieves this dictionary by using the method name of the dictionary as a key and specifies a processing function to every object. Then the interpreter 15 starts the specified processing function and executes this function.

Title: Ceramic sensor for detecting pressure or vibration and its manufacture
Inventor: OGAWA KAZUNOBU
IPC: G01L9/08
Filed: 1990-11-29
Abstract: PURPOSE:To achieve a highly sensitive detection with a wide directivity by forming a ceramic sintered body consisting of a dome-shaped curved surface and a flange part which is formed in one piece at this periphery and then baking a circuit wiring on a surface of the former and an electrode on a surface of the latter. CONSTITUTION:A specified voltage is applied to an electrode 3 of a ceramic sensor 1 and then the sensor 1 is direction to an object to be measured which generates a fluid pressure or sound pressure, thus enabling a mechanical deformation distortion to be generated at a curved part 1a due to the generation pressure and a circuit wiring 2 to be extended and contracted accordingly for generating distortion. Therefore, the applied voltage is deformed and a fluid pressure is detected, thus enabling a dome-shaped curved part (a) to detect a pressure wave reaching from a wide range, high rigidity of the ceramic sintered body to prevent a divided resonance which becomes an electrical signal noise for performing an accurate measurement with less harmonic distortion.

Title: Digital relay unit
Inventor: KATO HITOSHI
IPC: H02H3/05
Filed: 1989-12-25
Abstract: PURPOSE:To prevent total interruption of power system by detecting a fault instantaneously through a digital relay arranged in an upstream protective section even if the fault occurs in the power system when a digital relay ar ranged in a downstream protective section is under automatic inspection. CONSTITUTION:If a fault occurs in a downstream protective section when any one of downstream digital relays 6, 7 is subjected to inspection, and if the fault is not detected by the other downstream digital relay 7 or 6, an upstream digital relay 5 makes a judgment that the fault has occurred in a protective section allocated to the digital relay 6 or 7 under inspection. Consequently, the upstream digital relay 5 provides a trip output to a circuit breaker 3 or 4 for that protective section. By such arrangement, the upstream digital relay 5 detects a fault in the power system instantaneously even if the fault occurs when the downstream digital relay 6 or 7 is subjected to automatic inspection and protects the system positively.

Abstract: PROBLEM TO BE SOLVED: To provide a more comfortable air conditioning space to a user by allowing an air conditioner to cope with abnormality and promptly notify the user the abnormality as well as failure in the case where such abnormality or failure occurs in a humidity sensor or a detection signal processing circuit of the humidity sensor. SOLUTION: When humidity detected by the humidity sensor becomes not less than or not more than a given value, determination is made that failure has occurred in the humidity sensor or its detection signal processing circuit to conduct air control for a given period of time by every set level of humidity. Also, in such a case, indication of 'high humidity' or 'dehumidification required' is made at a humidity display. Subsequently, the humidity display is changed to a time mode through which a humidity difference indicating means indicates, after lapse of a given time, that 'a set humidity has been reached' or 'the current humidity is close to the set value'.

IPC: F02D41/34
Filed: 1992-12-15
Abstract: PURPOSE:To compensate a quantity of fuel adhering to an intake manifold so as to secure favorable air-fuel ratio control of an engine by correcting to increase a quantity of injection fuel of cylinders in an intake stroke in the case of asynchronous injection in the engine provided with fuel injection valves of a multiple point type. CONSTITUTION:An engine 10 is provided with, e.g. four cylinders 12A12D having fuel injection valves 30A-30D, respectively. A controller 22 controls the fuel injection valves 30 on the basis of signals detected by sensors 14, 20, 24, 26, 28 for detecting an operating condition of the engine 10. The controller 22 increases a quantity of fuel to be injected to the cylinders 12 in an intake stroke at the time of asynchronous injection where fuel is injected to the cylinders 12 simultaneously larger than that to be injected to the cylinders 12 in strokes other than the intake stroke. Consequently, it is possible to compensate a quantity of the fuel adhering to a wall surface of an intake manifold 16 by an effect of an intake air flow so as to secure performance of the engine 10.

Title: Electrically driven chucking device
Inventor: HARADA MASANOBU
IPC: B23B31/117
Filed: 1988-12-29
Abstract: PURPOSE:To retain the gripping power of a chuck by deterring rotation on an increase of power through the arrangement of No.1 and No.2 elastic members on both ends of a screw nut threadedly engaged with an index shaft which opens and closes chuck claws. CONSTITUTION:Claws of a chuck installed on the main shaft of a lathe 30 are opened and closed by turning a screw nut 28 through a speed reducer 13, an electromagnetic clutch 20 and a spline shaft 25 after the driving of an electric motor 11, and having an index shaft 39 threadedly engaged therewith reciprocated. When a work is gripped by a chuck through the application of inner tension/ outer clamping, a positive or a negative power acts on the index shaft 39 to compress disc springs, 41 or 42, located on both ends of the screw nut 38 and to deter rotation. The rotation of the electric motor 11 is stopped when a specified amount of deflection is detected by a load cell, 35 or 36. Hence, it becomes possible to retain the gripping power of a chuck and to prevent a work being gripped from getting loose.
