Title: Maintenance using fault information
Inventor: ITO AKIRA
IPC: G06F11/34
Filed: 1993-11-19
Abstract: PURPOSE:To prevent trouble by relatively low frequency fault and to speedily, surely, and easily analyze the fault by counting records of fault of the same kind in case of fault occurrence, and erasing the oldest record of the same fault when a certain specified number is exceeded and allocating the record which becomes free to a record of fault. CONSTITUTION:This system is equipped with a means 121 which gathers information on the state of a device at the time of fault occurrence, etc., and a means 122 which counts the number N of identical faults which are already recorded in an error log recording area to check whether or not the number is less than a maximum number Nmax prescribed in the system. Further, the system is equipped with a means which selects a record to be erased from the error log storage area 131 based on the check result of the fault record quantity check means 122 and replaces it with a record of fault. Consequently, an error log storage means 123 selects the record in the error log storage area 13 according to the decision result, erases the error log of the oldest fault occurrence time among all logs, and allocates the record which becomes free.

Abstract: PURPOSE:To make a circuit be in a safe OFF state independently of the adhesion strength of a contact point and simplify the assembly of an apparatus by connecting a fixed terminal plate and a heater terminal plate by a low melting point metal and installing the low melting point metal in the outside of a case. CONSTITUTION:A projected part of a fixed terminal plate located in the outside of a case and a projected part of a heater terminal part are connected with a low melting point metal 26. A load current flows in the circuit composed of the heater terminal plate, a heater 25, the low melting point metal 26, a bimetal plate 18, the fixed terminal plate, etc., and the heater 25 and the plate 18 radiate heat in proportion to the amount of the current. When it becomes overloading, the current increases and in the case the temperature of the plate 18 becomes a set level or more, the plate is changed reversely to part the contact point and shut the circuit. Then, when the load is cooled and the temperature of the plate 18 becomes a set level or less, the plate is returned to the original position and electricity is conducted and in the case overloading state continues and reverse returning occurs repeatedly and the contact point deposition occurs, the metal 26 is ruptured by the heat from the heater 25 and the plate 18 and the circuit 25 is kept in safe OFF state. The assembly is simplified by setting the metal 26 in the outside.

Title: Device and method for generating reactive power
Inventor: FURUTA MICHIHIRO
IPC: H02J3/18
Filed: 1994-11-25
Abstract: PURPOSE: To reduce the voltage variation of an electric power system and prevent a rush current from flowing to a load by limiting a delay-phase reactive current according to an increase in load reactive current. CONSTITUTION: A bias reference determining circuit 20 generates a variable bias reference corresponding to the variation quantity of an inputted load reactive current and also generates a fixed bias reference for outputting a specific reactive current from the inputted load reactive current, and outputs the composite value of both the bias references as a bias reference (iB). When a capacitor 4 is disconnected from a system by a breaker 52F, only the variable bias reference is outputted and when the capacitor is connected to the system, the composite value of the variable bias reference and fixed bias reference is outputted to reduce the voltage variation of the power system. When a load breaker 52DC is turned ON, on the other hand, an on-delay circuit 18 suppresses the rush current to the load 2 by suppressing a compensating current reference until certain time.

Abstract: PURPOSE:To enable keying operation which is stable and secure for a long period by providing a rotational fulcrum abutting part which has an arcuate part having the same curvature with the arcuate part of a rotational fulcrum part to the rear part of a key. CONSTITUTION:A key 3 is arranged rotatably on a key support member 21 and the rotational fulcrum part 27 has specific width larger than the width of the side wall of the key 3 in the width direction of the key 3 and forms part of the key support member 21 having the arcuate part as any sectional shape vertical to the width direction within the specific width. The rotational fulcrum abutting part 28 has the arcuate part having the same radius of curvature with the arcuate part of the rotational fulcrum part 27 which abuts slidably on the arcuate part of the rotational fulcrum part 27 to specific width behind the play part of the key 3. Further, the key support member 21 is freely attached to and detached from a keyboard frame 1. Consequently, the arcuate rotational fulcrum part and rotational fulcrum abutting part are large in contacting area and slide during the movement of the key to vary, but the variance of the surfaces is uniformed because of large slide surface area. Consequently, the influence of the variance upon a key touch feeling is eliminated and the secular change of the contact surface is small.

Title: Zinc alkaline battery
Inventor: KAGAWA KEIICHI
IPC: H01M4/06
Filed: 1985-12-26
Abstract: PURPOSE:To obtain a zinc alkaline battery whose hydrogen gas evolution from amalgamated or non-amalgamated zinc or zinc alloy used as a negative electrode is remarkably retarded by adding a specified amount of sulfolane as an inhibitor in an electrolyte comprising alkaline aqueous solution. CONSTITUTION:In a zinc alkaline battery using alkaline aqueous solution as an electrolyte and zinc or zinc alloy as a negative electrode, 0.2-5.0wt% sulfolane based on the alkaline aqueous solution is added to the electrolyte. Even when zinc alone is used as the negative electrode, the amount of hydrogen gas evolution is retarded. When zinc alloy containing one or more of lead, cadmium, indium, thallium, gallium, and aliminum is used as the negative elec trode, the effect is increased. When amalgamated zinc or amalgamated zinc alloy made of the zinc alloy is used, hydrogen gas evolution is furthermore decreased.

Title: Shift operating device
Inventor: NAKADA MASAYOSHI
IPC: F16H61/24
Filed: 1991-11-08
Abstract: PURPOSE:To facilitate a manual shift operation by constituting it from a first energizing means acting with the specified total range of a link flexible part and a second energizing means being larger in an elastic modulus than the former and acting out of the setting range at the central side, respectively. CONSTITUTION:When a shift operator 20 is slowly operated, two link flexible parts 12, 13B move against a first energizing means 13A, but a movement of this shift operator 20 is detected by a sensor 22, and an actuator 24 operates and it is shift-operated, so a second energizing means will in no case work. When the shift operator 20 is quickly operated, detection of the sensor 22 and operation of the actuator 24 are carried out, and since operating speed goes beyond actuating speed of the actuator 24, the link flexible parts 12, 13B is shifted up to a range where the second energizing means 13B gets acting, thereby receiving an energizing action. Operating force is transmitted to a gear shifter 3 by the second energizing means 13B via link mechanisms 8-17. Therefore shift operability is thus improved.
