Title: Antiseismic safety breaker with built-in confirmation device
Inventor: SUZUKI AKITO
IPC: H02H5/00
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To provide an antiseismic safe safety breaker with a built-in confirmation device by automatically breaking an AC power source within a building such as a residence, a factory, a store, mansion, an apartment, a school, a poultry pen, a pig pen, and others, by vibration. SOLUTION: Commercial AC power within a building such as a residence, a factory, a store, a mansion, an apartment, a school, a poultry pen, a pig pen, and others is automatically broken by vibration. This safety breaker 3 automatically breaks power with vibration such as earthquake, so it is safe, and if commercial AC power 2 is applied, a pilot lamp 5 lights, so it can be confirmed that the power is on to the breaker 3. If power is turned on close to the breaker 3, it will do to shove in the lever 4 of the breaker 3 after confirming the safety. Hereby, the secondary disaster can be minimized.

Title: Eddy current type speed reducer
Inventor: ARAKI KENJI
IPC: H02K49/02
Filed: 1988-03-14
Abstract: PURPOSE:To make braking power needless by controlling the overlap between a supporting plate, whose center is supported, freely in rotation, by a rotary shaft and Whose periphery is fixed to a car body and whose both sides are arranged with fan-shaped permanent magnets, and a supporting frame which has a pole piece. CONSTITUTION:A supporting plate 3 through the central hole of which a rotary shaft 5 is inserted is pivoted freely in rotation on the rotary shaft 6 with a bearing 6, and the supporting plate 3 is fixed to the car body with a flange 8 provided at the periphery. Fan-shaped permanent magnets 4 are split into two and attached to both sides of the supporting plate 3. A supporting frame 1 which has pole pieces A corresponding to permanent magnets 4 and shunt plates 13 located between them is overlaid. A rotor 7 fixed to the rotary shaft 5 is made to correspond to the supporting frame 1 with space between. The supporting frame 1 is rotated by moving a lever 10 which is mounted to the supporting frame 1 with a lever mounting washer 9 so as to adjust overlapping area between the permanent magnet 4 and the pole piece A to adjust braking force arising in the rotor 7. Hereby, power for braking becomes needless and it becomes economically advantageous.

Title: Binary signal generating circuit
Inventor: SATOU YOUJIROU
IPC: H04N1/403
Filed: 1979-05-19
Abstract: PURPOSE:To enable to obtain an excellent binary signal even with an original without white part at the initial of scanning, by the sample hold of peak value immediately before a peak hold circuit which produces a threshold voltage to binarize a  video signal is reset. CONSTITUTION:A video signal Sa read out and amplified A at an image sensor IS is held for the peak voltage at a peak hold circuit PH, and a voltage Pp is output to a sample hold circuit SH. The circuit PH is reset with a signal Pr from a timing pulse generator TPG within nonvideo signal period, but TPG feeds a signal Ps to the circuit SH immediately before the reset and the peak value held at the circuit PH is sample-held to output a voltage Ph. The threshold voltage dividing this voltage Ph by a resistor VR is given as the reference voltage Vs of a comparator COMP. COMP compares the signal Sa with the voltage Vs to output a binary signal. Thus, a suitable binary signal is obtained even to an original without white part at the beginning of scanning of the original.

Title: Wire of superconductive oxide
Inventor: NUMATA KOICHI
IPC: C04B35/45
Filed: 1989-03-16
Abstract: PURPOSE:To lower contact resistance by composing an electrode joining part with a powder mixture of a metal powder which is poorly reactive with an oxide and an oxide powder. CONSTITUTION:In packing a superconductive oxide powder in a metal sheath, a powder mixture of a metal powder which is poorly reactive with the superconductive oxide and the superconductive oxide powder is filled in the end part of the sheath to become a joining part of an electrode, then an oxide powder only is filled, and finally a mixture of the same metal powder and the superconductive oxide powder is filled in the other end. The resultant sheath is extended by cold-processing, made into a wire with a desired diameter, and heated for sintering. As a result, current pass is caused no only in superconductive oxide or the sheath to the superconductive oxide but in the metal powder to the superconductive oxide or the sheath to the metal powder to the superconductive oxide powder, and the surface area of the electric current is increased. By this, contact resistance is lowered.

Title: Petroleum combustor with automatic small combustion wick lowering mechanism
Inventor: KATSUMATA KOJI
IPC: F23D3/28
Filed: 1993-02-26
Abstract: PURPOSE:To automatically control a room temperature by actuating a solenoid to lower a burning wick to a position corresponding to small combustion when the room temperature rises to a predetermined temperature or higher. CONSTITUTION:When a room temperature rises to a predetermined temperature or higher during combustion, a solenoid 4 is actuated to push an operating plate 8 to disengage a latch 8a from a reset plate 6, so that the reset plate 6 is turned toward a position corresponding to small combustion. At this time, the reset plate 6 turns a wick moving lever 5, which abuts against the reset plate, in a wick descending direction to cause combustion to continue at a position corresponding to minimum combustion. When the minimum combustion is continued with the result that the room temperature falls below a predetermined temperature, the wick moving lever 5 is turned in a wick raising direction, so that a burning wick is raised and the reset plate 6 engages with the latch 8a of the operating plate 8 to cause combustion at a maximum rate of combustion. When the room temperature rises to the predetermined temperature, the burning wick descends to the position corresponding to minimum combustion owing to the action of the solenoid for continuation of combustion whereby the room temperature can be automatically controlled.

Filed: 1992-03-19
Abstract: PURPOSE:To improve the surety of operation by connecting an antiparallel circuit comprising diodes to a photo triac used for an output AC switch in a DC-AC solid-state relay employing a photo triac coupler. CONSTITUTION:A diode anti-parallel circuit 7 employing a voltage drop use semiconductor element is connected in series with a photo triac acting like an output AC switch of a DC-AC solid-state relay SSR employing a photo triac coupler 5.

Title: Resonance switching power supply
Inventor: OKADA YUKIO
IPC: H02M3/28
Filed: 1991-03-27
Abstract: PURPOSE:To suppress switching loss and switching noise upon turn ON of a switching element. CONSTITUTION:Upon turn OFF of a switching element SW, a resonance circuit is formed of the primary coil L1 of a transformer (50) and a resonance capacitor CRE and the voltage between the electrodes to be controlled of a switching element varies limitedly. A voltage detecting circuit comprising a diode D2, a resistor R9 and a transistor Q0 detects a minimal point of the voltage between the electrodes to be controlled and triggers the CT terminal of a control circuit (20). The control circuit (20) outputs a high level at the OUT terminal for a predetermined time after triggering of the CT terminal thus turning the switching element SW ON. Since the switching element SW is turned ON at a time point when the voltage between the electrodes to be controlled has a minimal value, switching loss can be neglected.
