Patent JP-S6075131-A (JP)
Title: Voice defeat circuit
Inventor: NAKAO CHISATO
IPC: H04B1/10
Filed: 1983-09-30
Abstract: PURPOSE:To prevent generation of unnecessary sound when power is reapplied by detecting a voltage drop of a power supply for sound demodulation circuit so as to decrease an input bias of a sound output circuit thereby stopping the operation of the sound output circuit. CONSTITUTION:A voltage of a 12V line of the power supply for sound demodulation circuit is dropped earlier when power is interrupted, and it is detected by a transistor (TR)11, which is turned off. Since a 30V line of the power supply for sound output circuit falls down slowly, a TR12 is turned on, an electric charge stored in capacitors 15, 16 is discharged and an input bias is lowered and also the 30V line potential is dropped through a resistor 20. As a result, the operation of the sound output circuit 1 is stopped and a pulse rising when power is restored is not amplified by the sound output circuit 1, allowing to prevent generation of unnecessary sound.

Title: Refrigerator for vegetable storage
Inventor: MAEKAWA YUKIHIRO
IPC: B01D53/22
Filed: 1990-07-10
Abstract: PURPOSE:To keep the inside of a storage box at a proper humidity to allow a long period storage of vegetables free from dew drops on the inside surface of the box by permeating steam over saturation humidity which is emitted from stored vegetables in the box due to transpiration function and respiration function through a moisture permeable film of a lid of the box. CONSTITUTION:A storage box 7 is approximately sealed by a lid 10 so that cold air does not directly penetrate into the box, and the inside of the box 7 is kept high humid due to steam transpirated from stored vegetables 17. Steam over saturation humidity produced in the inside of the box is gradually permeated into a cold air convection path 9 in which low humid cold air flows through a moisture permeable film 13 on the surface of the lid 10 of the box. Therefore, the inside of the box 7 is free from dew drops, causing no damage to the vegetables 17 by water drops or being in contact with water, and allowing the vegetables 17 to be kept fresh for a long period without drying or withering. Further, a wide opening of the lid 10 is convenient for putting in and taking out the vegetables.

Title: Sense amplifier circuit
Inventor: INUKAI HIDEMORI
IPC: H03F3/34
Filed: 1983-10-03
Abstract: PURPOSE:To ensure the stable and high-speed actuation of a sense amplifier circuit by separating are amplifying function into a primary and secondary amplifications and starting the secondary amplification by a transistor which is controlled with the reception of the output of the primary amplification. CONSTITUTION:A different potential is produced between the levels of nodes N11 and N12 after activation of phi1. For nodes N13 and N14, the level of the N13 starts a rise when the N11 has a change between high and low levels. Then a transistor (TR)Q18 is turned on and increases the amplification degree by a TRQ15 and a TRQ16. The level of the N13 rises high to increase the amplification degree. Finally the level of the N11 is changed completely to a low level to end the amplification of the N11. In such a way, both TRQ15 and TRQ16 are actuated after separating the 1st amplification of a TRQ13 and a TRQ14 from the 2nd amplification of the TRQ15 and TRQ16 and the amplification levels of the TRQ13 and TRQ14 are fed back. This secures the stable and high-speed actuation of the sense amplifier circuit.

Title: Fluorescent display tube
Inventor: TOKI HITOSHI
IPC: H01J29/20
Filed: 1981-11-17
Abstract: PURPOSE:To obtain a fluorescent display tube, which has a greatly enhanced luminous efficiency and can realize a bright display, by coating a positive conductor with a phosphor layer, which is prepared from a ZnO-Zn phosphor with a mean grain diameter of between 5mum and 50mum. CONSTITUTION:When a phosphor layer 5 is formed by using phosphor particles with a large grain diameter, since the times of absorptions and acatterings of light at the interfaces of the particles are reduced, the attenuated degree of emissions taken outside the layer 5 can be widely decreased. In addition, the increased grain diameter of a phosphor reduces the amount of a binder used for joining the phosphor particles and joining the phosphor particles and a positive conductor 4. Besides, since the surface area of the phosphor particles is decreased, there is a small fear of the surfaces of the phosphor particles being contaminated during the manufacturing process of a fluorescent display tube. As a result, the surfaces of the phosphor particles are maintained clean, and the luminous efficiency of the phosphor itself can be enhanced.

Abstract: PURPOSE:To reduce the cut-off space of a filter device and to minimize the structure of said filter device by providing dielectric coaxial resonators at both sides of a signal transmission line and setting the open terminals of resonators of the n-th stage and and the (n+1)-th stage obliquely and opposite to each other to have a connection between both resonators by means of a capacitor. CONSTITUTION:Dielectric coaxial resonators 2 making use of resonance in a coaxial TEM mode are provided at both sides of a signal transmission line 1. At the same time, the open terminals of the resonators 2 of the n-th stage and the (n+1)-stage (n: a natural number) are set obliquely and opposite to each other. These open terminals are connected to each other with a capacitor. Then the capacitors of the first and the final stages are connected with an input connector 3 and an output connector 4 respectively. Thus, an unmatched state between both resonators 2 owing to an increment of distance between these resonators 2 is avoided and a cut-off space between both open terminals is reduced. As a result, a filter device can be miniaturized.
