Title: Speaker protector
Inventor: MORITA SHIGERU
IPC: H04R3/00
Filed: 1977-11-02
Abstract: PURPOSE:To protect a speaker with an inexpensive and small size divice by actuating a protecton switch control relay with a relay which actuates when the signal comprising delaying amplifier output exceeds a set value. CONSTITUTION:The amplifier output being applied between terminals 1, 1' is rectified with a rectifier 5 and is converted to a d.c. voltage corresponding to the above output after waiting for a time delay between both terminals of a capacitor 16. When this reaches a certain set value or higher, a coil 11 is energized. As a result, relay contacts 12 close to energize a coil 8, causing in turn the normally closed contact 4a of the switch to open and the normally open contact 4b to close. A speaker 3 is thereby protected. In this case, the current flowing in the coil 8 is so smaller than the speaker current that the relay consisting of the contacts 12 and coil 11 can be of a small capacity and since the winding resistance of the coil 11 may be made large, the capacity of the capacitor 16 may be reduced by increasing the value  of a resistance 15. Thereby, the speaker is protected by the inexpensive and small  size device.

Abstract: PURPOSE:To perform safe positive and negative switching, by a method wherein a positive thyristor bridge is turned off and a negative thyristor bridge is also turned on by a phase going the voltage of the turned on element to negative at the final stage for the other phase voltage. CONSTITUTION:An AC power source 1 is applied to thyristor bridges 3A, 3B through a transformer 2 and the power is supplied to a load 4. And the signal in an output current detection circuit 6 consisting of a current detector 7 and a current polarity detector 8 is fed into a firing control circuit 9 together with a phase detection circuit 12, a phase control signal 10, and a switching signal 11 to control the commutation phase of the bridges 3A, 3B and after turning off the positive bridge 3A, a firing pulse is fed into the negative bridge 3B by the phase going the voltage of the turned on element to negative at a final stage for the other phase voltage. Therefore, safe and sure positive and negative switching can be performed with a slight zero current period without causing power source short-circuit loop.

Title: Electromotive wheel chair
Inventor: CHIYAARUZU MATSUKINTOTSUSHIYU
IPC: A61G5/04
Filed: 1980-09-24
Abstract: A wheelchair assembly includes an occupant seat having a central shaft for mounting the seat on an undercarriage for universal tilting movement, for vertical movement along the shaft axis and for rotation about such axis. The undercarriage has a plurality of ground engaging wheels driven together by a driving mechanism which includes a drive motor and steered together by a steering mechanism which includes a steering motor. The steering motor may be operatively connected with both the seat and the wheels for turning them together by operation of a control assembly, or the steering motor may be operatively connected with only the seat or with only the wheels for independent operation. Otherwise, the steering mechanism may couple the seat with the wheels while the steering motor is disconnected so that wheel steering may be operated by a manual turning of the seat. An analyzer assembly compares the direction of travel chosen by the seat occupant to the actual orientation of the wheels and then directs the steering motor to align the wheels to the direction chosen, without turning the chair. And, the seat is automatically tilted toward a direction opposite that to which, it tends to lean when the wheelchair moves up an incline or down a decline.

Title: Direct hardening method of steel plate
Inventor: YOSHINAGA HISASHI
IPC: C21D1/18
Filed: 1979-10-16
Abstract: PURPOSE:To improve the flatness of a steel plate and decrease the variance in mechanical properties by flattening the same with a hot leveler right after hot finish rolling then hardening the same with a roller quench type hardening apparatus. CONSTITUTION:The thick steel plate having been emitted from an ingot heating furnace 1 for slab etc. and hot rolled by a roughing mill 2 and a finishing mill 3 is passed through a hot leveler 4, whereby it is corrected of the distortions produced by the rolling to have better flatness. Thence, this steel plate is hardened by means of a roller quench type hardening apparatus. In the apparatus 5, it is hardened while it is grasped and conveyed by upper and lower rollers, hence, the cambers in the longitudinal and width direction of the thick steel plate are suppressed. Because of this, the thick steel plate is hardened at a uniform and proper hardening temperature from the leading end up to the trailing end. After the hardening, it is subjected to ordinary annealing with an annealing apparatus 6.

Title: Conjugate non-woven fabric and production thereof
Inventor: HONDA YOSHIHIRO
IPC: D04H5/03
Filed: 1989-05-26
Abstract: PURPOSE:To obtain the subject non-woven fabric excellent in balance of strength and softness and in water absorption properties by piling up a sheet-shaped material composed of short fibers on a sheet-shaped material composed of filaments consisting of a sheath-core type conjugate fiber and carrying out water jet entangling treatment in plural times. CONSTITUTION:On one or more sides of a sheet-shaped material composed of filaments consisting of a sheath-core type conjugate fiber in which a polymer having a lower melting point than that of the core component is used as the sheath component, a sheet-shaped material composed of short fiber web or pulp of a natural fiber is piled up. The resultant laminated material is placed on a porous supporting member and led to collide with a fluid jet having <30kg/cm<2> pressure to preliminarily entangle both the sheet-shaped materials. The obtained preliminarily entangled material is then led to collide with a jet of >=50kg/cm<2> to mutually entangle both the sheets without cutting the fibers constituting the above mentioned laminated sheets, thus obtaining the objective conjugate non-woven fabric having >=11kg tensile strength, <=65g softness and <=5sec. water absorption properties. The above mentioned non-woven fabric can be widely utilized in fields such as a wiping cloth, a dehydrating roller material and a material for clothes.

Abstract: PURPOSE:To provide a liquid crystal display cell which has a large hysteresis width and exhibits steep rise and fall characteristics by using the liquid crystal display cell of which the transparent electrodes patterned on a glass substrate are rounded in angles by an annealing treatment. CONSTITUTION:The liquid crystal display cell which utilizes the bistability of a nematic-cholesteric phase transition is used after the transparent electrodes patterned on the glass substrate are rounded in angles by the annealing treatment. In2O3 is decomposed by sublimation at 850 deg.C in the case of using this material as the transparent electrodes and therefore the annealing can be successfully executed simply by heat-treating the glass substrate having the transparent electrodes for 1-2hr at 400-600 deg.C. The large hysteresis width is thereby assured and the stable nematic-cholesteric phase transition type display is attained.
