Title: Piezoelectric actuator and its assembling method
Inventor: UENODAI ASAO
IPC: H01L41/083
Filed: 1994-08-03
Abstract: PURPOSE:To reduce the probability of breakdown of a piezoelectric element which is caused by tensile stress, by applying preliminary pressure to the element without applying tortional stress to the element. CONSTITUTION:A piezoelectric element 2 is accommodated in a case 4, and fixed on a pedestal 3 of the case bottom. An elastic member, e.g. a coned disc spring 7 is arranged between a lid 5 and a piston 6. Preliminary pressure is applied to the element 2 by an assembling method, in the state that tortional stress is not applied by adjasting the position of the lid 5. Strain gauges 8, 9 for detecting strain of the element 2 are fixed on the outer peripheral surface of the element 2, for the inputting to a preliminary pressure adjusting equipment. The outputs of the strain gauges 8, 9 are inputted in bridge circuits 20 and 21, respectively, which have a source power supply VSO. Hence the preliminary pressure is applied to the piezoelectric element 2 without applying tortional stress, and maintained. Thereby the probability that the piezoelectric element 2 is broken down by tensile stress can be reduced.

Title: Arithmetic processor
Inventor: ISHIBASHI FUMIAKI
IPC: G06F12/08
Filed: 1990-07-11
Abstract: PURPOSE:To lower the generation probability of a restart processing caused by a comparison fault or a majority fault by requesting the reissue of an instruction, in the case of an error, etc., are detected by at least one piece of cache, and also, informing all caches of the generation of a fault and making cache data of the corresponding address invalid. CONSTITUTION:When a cache 21 generates a cache fault by a read-out operation, the cache 21 sets a cache error signal 111 to '1'. Subsequently, an OR circuit 40 generates a bus error signal 113, and distributes its signal to processors 10-12 and caches 20-22, respectively. When a bus error signal 113 is informed, the processors 10-12 suspend receiving the data sent through signal lines 130-132, and also, request a re-read-out operation of an instruction or data issued immediately before an input of the bus error signal 113 to the respective caches 20-22 through the signal lines 130-132. In such a way, the generation probability of a restart processing operation caused by a comparison or majority fault becomes low.

Title: Cooking heater with overheat-ignition preventing function for tempura oil
Inventor: KOBAYASHI ISAO
IPC: A47J27/00
Filed: 1995-06-28
Abstract: PURPOSE: To eliminate a safety circuit and reduce cost by using a positive characteristic thermistor to allow occurred abnormalities to act on the safety side, i.e., on the temperature rise side, and satisfy an overheat ignition preventing function even if the abnormalities occur in a temperature sensor. CONSTITUTION: An electric resistance value of a positive characteristic thermistor built in a temperature sensor 10a starts to abruptly rise even if the temperature of the lower surface of the bottom part of a heated vessel 1 during cooking rises to a predetermined temperature, and a first electromagnetic valve 2 reduces the electrification to an excitation winding or is shut off to be opened so that the supply of fuel gas is shut off to stop the combustion of a burner 9 and prevent tempura oil to be heated from heating ignition. Since the positive temperature coefficient thermistor is used, when the thermistor itself is damaged and when the lead wire of the thermistor gets out of the thermistor or disconnected, the supply of combustion gas is shut off to extinguish a fire, so that a safety circuit is not particularly required to be provided and the constitution is simplified.

Title: Control system for shared resources in data communication network
Inventor: MIYANO SOICHIRO
IPC: G06F15/16
Filed: 1985-08-20
Abstract: PURPOSE:To improve the flexibility of the titled control system by transmitting the acknowledge to a data processor at the side of a transmitter of the use end signal after confirming the data processor that sent the use request signal for a data input/output device and storing the information showing an unused state in a using state display means. CONSTITUTION:The use request signal for a data input/output device 2 is sent to a data processor 3 and the acknowledge is received from the processor 3. Then the use of the device 2 is started. When the use is through with the device 2, the use end signal is sent to the processor 3. The processing is through as long as the acknowledge signal is received successfully from the processor 3. If the reception of the acknowledge signal fails, the operation is repeated until this signal is received. The control of the device 2 is simplified because it is just needed to use the device 2 with a single processor 3 at all times and since the using state is controlled by the processor 3. Thus it is possible to scatter the load to plural data processors and also to improve the flexibility with the change of this control system.

In addition, dirts such as feces of fishes and scales are filtered, and cleaned sea water is returned into upper and lower parts of the tank 1 through a water supply pipe 4. By continuing the circulating operation, the fishes being bred in the tank 1 can be let to continue their sound growth. In addition, when precipitated dirts are fed into the tank 2 through a trapping pipe 7, both cleaning of the interior of the tank 1 and feeding of the microorganism can be achieved.

Title: Voice coil actuator
Inventor: YOKOUCHI HIDEYA
IPC: H02K33/18
Filed: 1980-12-25
Abstract: PURPOSE:To simplify the manufacture of a voice coil by disposing a planar coil in an air gap of a magnetic circuit and producing thrust force by poles faced oppositely to the direction of a current flowing through the coil. CONSTITUTION:A magnet 2 is securd to a magnetic circuit 1. Yokes 4 are installed at the oppositely facing positions. A coil 3 wound in a planar state of  movable structure is placed in the air gap between the magnet 2 and the yokes  4. Since a current is flowed through the coil 3 at this time, the directions of the  currents in the magnetic field are opposite. Thus, the thrust forces produced in  accordance with Fleming's left hand law becomes the same direction. In this manner, the coil 3 can move in the air gap between the magnet 2 and the yokes  4. Accordingly, it is not necessary to magnetically connect the magnetic circuit  1 to the yokes 4, and the magnet 2 can be produced in an integral construction.
