Title: Protective device for superconducting device
Inventor: YAMADA TADATOSHI
IPC: H01F6/02
Filed: 1983-10-19
Abstract: PURPOSE:To shorten the time constant of a transient phenomena of superconducting coil currents by connecting a diode circuit in parallel with a permanent current switch and mounting the diode circuit in a cryogenic region. CONSTITUTION:A permanent current switch 2 and a diode circuit 9 are connected in parallel with a superconducting coil 1. The coil 1 is excited by an excitation power supply 7, and the switch 2 consists of a permanent current switch superconductor 4, a heater 5 for heating said superconductor and a heat insulator for heat-insulating both from a refrigerant. The circuit 9 is mounted in a cryogenic region, and turn-on voltage vt2 reaches to several V. When the turn- off voltage vt2 of the circuit 9 is made larger than excitation voltage, the resistance of the circuit 9 reaches to infinity. Accordingly, the time constant of the excitation currents of the coil 1 is determined by the inductance of the coil 1 and the normal conductive resistance of the superconductor 4 for the switch 2, and can be reduced.

Title: Tracking device
Inventor: USUI MASAHIRO
IPC: B65G43/08
Filed: 1993-08-09
Abstract: PURPOSE:To provide a tracking device which can enhance the consistency of the position of a substance and tracking information when a substance carrying system starts after it has stopped by providing a restarting value correction means which corrects tracking position information by a tracking means by the difference between a read-out count value and a present count value. CONSTITUTION:When no change has been made in the position of a substance during the period of time from the time when a carrying line was suspended to the time when the line is restarted, tracking information is corrected by a restarting value correction means 24 by the difference B1-B2 between a count value B1 read out of a non-volatile memory 27 and a present count value B2 by a pre-set counter 18, tracking information thereby becomes substantially continuous to information at the time when a carrying line was suspended. Therefore, even if the pre-set value or the count value of the pre-set counter 18 is different from that when the line is suspended during the period of time from the time when the line was suspended to the time when the line is restarted, events take place in a form substantially continuous to the time when the carrying line was suspended, besides, tracking information with the position of a substance can thereby take place.

Title: Time-out detecting circuit
Inventor: IIDA SHOZO
IPC: G06F11/30
Filed: 1987-08-06
Abstract: PURPOSE:To shorten the waiting time needed for the useless processing that is carried out continuously until a series of actions are through, by detecting a time-out state when the started clocking action of a clocking means is not discontinued within a prescribed time. CONSTITUTION:A comparator 10 outputs a start signal 102 when the coincidence is obtained between the read address held by a read address register 6 and the address stored in an address buffer 8. While a comparator 11 outputs a stop signal 103 when the coincidence is obtained between the address stored in the buffer 8 and the address held by a forestalling address register 9. A timer 12 starts a count-up action with input of the signal 102 and then stops this action with input of the signal 103. Then the timer 12 outputs a time-out signal 104 after detecting a time-out state when the counting action is not stopped within a prescribed time. Thus it is possible to shorten the waiting time needed for the useless processing that is carried out continuously until a series of actions are through.

Inventor: DOMOTO HIROTOSHI
IPC: B21C47/00
Filed: 1988-08-05
Abstract: PURPOSE:To suppress a sudden fluctuation of a plate speed and to stably execute coiling and decoiling by compensating a speed reference value by a tension controller and limiting on output of the tension controller by a compensation output limiter. CONSTITUTION:An adder 19 operates a tension deviation being a deviation between a tension detection value which has been detected by a tension detector 17 and a tension reference value which is set by a tension setting device 11 and outputs it to a tension controller 12.

Title: Nickel hydroxide powder for positive electrode material and its manufacture
Inventor: FUNATSU EIJI
IPC: H01M4/52
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of discharge characteristics, shortening of life, and lowering of energy density, by causing a nickel hydroxide powder to include a specific rate of zinc and cobalt, making its particles spherical, causing the zinc to be annularly distributed in particle cross-sections, causing the powder to have a specific tap density, and causing a diffraction peak of a specific surface by X-ray diffraction to have a specific half value width. SOLUTION: Swelling of an electrode due to massive generation of γ-NiOOH is prevented by causing a nickel hydroxide powder to contain 1 to 3 wt.% zinc and 0.5 to 2 wt.% cobalt. By making its particles spherical, its tap density becomes 2.05 g/ml or more, and also its energy density is raised, but normally it is 2.20 g/ml or less. Annular portions in particle cross-sections having a high zinc concentration prevent generation of γ-NiOOH, and therefore only a small amount of zinc is needed. The half value width of a diffraction peak on a (101) surface by X-ray diffraction is caused to be 0.9 degree or more, and crystallinity is obtained that is suitable for easy proton movement and the high tap density.  It is preferable to produce this powder by simultaneous and continuous mixture of water solutions of nickel, of zinc/cobalt, and of a caustic alkali, and an ammonium-ion supplying body.

Abstract: PROBLEM TO BE SOLVED: To judge the failure mode of a variable power carriage in detail in the case of failure, by forming a latent image of a monochromatic pattern installed near a contact glass, onto a photoreceptor, and detecting the boundary of a white area and a black area. SOLUTION: A monochromatic pattern 10 is adhered to a lower face of a document scale 11 near a contact glass 1. When a standard position of a variable power carriage 5 can not be detected because of the failure of the variable power carriage standard position sensor and the driving system, the first scanner 2 and the second scanner 3 are operated for reading the potential (white VL, black VH) of a photosensitive drum corresponding to the monochromatic pattern 10, while holding the variable power carriage 5 at the current position. Then the variable power carriage 5 is moved by a predetermined amount, to read the potential of the monochromatic pattern.  The both rise times between the potential VL and VH, are compared, and it is judged that the change of scale factor is not performed when the rise times are agreed with each other, and the judgement is displayed on an operation panel as the failure of the variable power carriage driving system.
