Patent JP-S63252355-A (JP)
Title: Separator for lead-acid battery
Inventor: FUKUDA SADAO
IPC: H01M50/463
Filed: 1987-04-08
Abstract: PURPOSE:To increase cycle life and storage performance by forming recesses and projections on the surface of a mat made of glass fibers, synthetic resin fibers, or these mixture, and holding colloidal electrolyte in the recesses. CONSTITUTION:Recesses and projections are formed on the surface of a mat 1 made of glass fibers, synthetic resin fibers, or these mixture, and colloidal electrolyte containing sulfuric acid is filled in the recesses 2. Thereby, the colloidal electrolyte exists on the interface between the mat 1 and a plate, and the transfer of the electrolyte is made easy. Since the colloidal electrolyte has a thixotropic property, the viscosity is decreased by gas evolution during charge. However, since the electrolyte is filled in only the recesses 2, it stays in the recesses without transfer to other place and the effect is continued. Therefore, the cycle life, storage performance, overdischarge performance, and overcharge performance are increased.

Abstract: PURPOSE:To produce bimetal without degradation in a curving constant and mechanical properties by rolling an alloy on a high expansion side and an alloy on a low expansion side at the specific temp. higher than the martensite transformation temp. of the alloy on the high expansion side. CONSTITUTION:The temp. for rolling is set at the martensite transformation temp. of an alloy on a high expansion side that causes martensite transformation by cold rolling +30 deg.C, more preferably +60 deg.C, whereby the martensite transformation is prevented and the degradation in the curving constant occuring in the decrease in the coefft. of thermal expansion is prevented in the stage of producing bimetal by rolling said alloy on the high expansion side and an alloy on a low expansion side with or without intervention of an alloy of an intermediate layer. The rolling temp. is kept at <=500 deg.C to prevent the degradation in mechanical properties. Alloy steel contg. about 15-30wt% Ni and about 1-15% Cr is used as the above-mentioned alloy on the high expansion side and an invar alloy or the like is used for the alloy on the low expansion side.

Title: Display device for automatic dispenser
Inventor: WAKAGI SEIJI
IPC: G09F9/46
Filed: 1990-03-30
Abstract: PURPOSE:To change a display content by providing a dimmer sheet which is switched to a transparent state and a scattered state in accordance with the impression state of a voltage in front of a display panel. CONSTITUTION:The dimmer sheets 91-98 are arranged on characters such as 'Welcome' in the display panel 4. Transparent polymer where the grain-like liquid crystal of light scattering liquid crystal complex is dimmer is sandwiched between two transparent sheets and they are used for the sheets 91-98. When an electric field is impressed between the transparent electrodes, a refractive index in grain-like liquid crystal becomes equal to that of polymer and light passes through them without scatter. The refractive index of the grain-like liquid crystal differs from the refractive index of polymer and it scatters in a state where the electric field is not impressed. Thus, a change is given to the display state of the display content 3 and the attention of a user can be attracted.

Filed: 1979-07-10
Abstract: PURPOSE: To make a distance sensor high-precision and enhance reliability against mechanical and chemical disturbance to improve temperature stability, by providing a pulse magnetic field generator and so on to utilize the ultrasonic propagation characteristic of the continuous thin band of an amorphous magnetic alloy.  
     CONSTITUTION: When a pulse signal is input to pulse magnetic field generator 2 to exicite amorphous magnetic alloy continuous thin band 1, ultrasonic waves are generated. They are propagated in the longitudinal direction of thin band 1 and reach distance X from generator 2 to generate ultrasonic pulses. A pulse signal of change of the magnetic characteristic such as magnetic flux is generated by these ultrasonic pulses. Therefore, pulse voltage eOUT is generated in detector 35 placed at distance X. At this time, the pulse train signal input to magnetic field generator 2 and pulse voltage eOUT are used and are compared with each other by various methods to obtain the ultrasonic propagation time, and this time is proportional to distance X from generator 2 to detector 35, and therefore, a high-precision distance sensor can be constituted. The ultrasonic propagation property in the amorphous magnetic alloy is good, so that reliability against disturbance and temperature stability can be improved.

Title: Field-effect transistor
Inventor: GOTO NORIO
IPC: H01L27/095
Filed: 1989-04-07
Abstract: PURPOSE:To enable side gate effect to be controlled by forming a deep level which functions as a recombination center at a semi-insulating substrate region near the region where conductive type impurities are added. CONSTITUTION:In n-channel field effect transistor 21 and 22 formed on a semi- insulating substrate 9 made of GaAs, a deep level which functions as a recombination center is formed at semi-insulating substrate regions 7 and 8 near an n-type conductive layer. When an FET 21 is noticed and a neighboring FET 22 is set to a negative potential for the FET 21, a deep level which functions as a recombination center is placed at a semi-insulating region near the n-type region of the FET 22. The amount of positive holes which are implanted from the FET 21 side and are accumulated at a region where potential is flat near the FET 22 decreases due to recombination. Thus, expansion of the region where potential is flat for application of side gate voltage is controlled, thus restricting occurrence of side gate effect drastically.

IPC: H01J61/36
Filed: 1982-05-24
Abstract: PURPOSE:To obtain a double tube type lamp, in which the distance between electrodes is long despite its dimensions and which is easily manufactured, by fixing an inner bulb to the flare a steam by fusion or adhesion. CONSTITUTION:After an exhaust tube 7 and two electrode lead wires 8 are inserted in a glass tube 4 having a flare 9, one end of the glass tube 4 is heated and sealed. Next, an inner bulb 12 is directly fixed by fusion or adhesion to a part of the flare 9 which is located between a plural number of anodic lead wires 5 and 6 and the glass tube 4 of a steam, which is constituted by fusing the anodic lead wires 5 and 6 to the above flare 9. After that, the inner bulb 12 is sealed in an outer bulb 11 by fusion according to the convertional method, thereby completing assembly of a double tube structured lamp. By the means mentioned above, work of the lamp is remarkably facilitated, and the shift between the center axes of the inner and the outer tubes which may become a problem in a lamp of this type is greatly reduced. Consequently, an emissional polarization and the like can be almost prevented. Besides, owing to the increased distance between the electrodes, a high luminous output is realized despite the small size of the lamp, and the luminous efficiency is enhanced.

Filed: 1994-04-01
Abstract: PURPOSE:To make it possible to sufficiently use a diaphragm for speaker even under high temperature environments by composing the diaphragm of the diaphragm for speaker by spheroidal graphite cast iron. CONSTITUTION:A speaker 1 to which a diaphragm for speaker (diaphragm) la is applied has a yoke Y and a magnet M on the side of the base part of a cone-shaped frame F and the cone-shaped diaphragm 1a is provided at the inside of the frame F. A muffler using this speaker 1 is made to pick up noise by a microphone and to input this noise in a frequency analyzer via an amplifier. The thin plate of spheroidal graphite cast iron is used for the diaphragm 1a. This thin plate of spheroidal graphite cast iron is excellent in heat resistance because it is made of metal. Further, in this thin plate of spheroidal graphite cast iron, its acoustic characteristic exists in the range where the characteristic can be applied as the characteristic of a speaker because of the high damping capacity due to the spheroidal graphite included in the thin plate.
