Patent JP-H06140075-A (JP)
Title: Sodium-sulfue battery
Inventor: OTEGI SATORU
IPC: H01M10/39
Filed: 1992-10-22
Abstract: PURPOSE:To prevent force applied to a solid electrolyte tube even if thermal deformation is caused when a temperature of a positive electrode structure body is lowered as well as to avoid breakage of the electrolyte tube by setting a ratio of linear expansion coefficients in a radial direction and a circumferential direction of the positive electrode structure body in a battery three times or larger than that. CONSTITUTION:A sodium - sulfur battery is composed of a negative electrode active material 1 composed of fused sodium, a solid electrolyte tube 2 composed of beta''-alumina to surround this and a positive electrode structure body 3 composed of carbon fiber felt being an electrical conductive body 7 and sulfur 8 being a positive electrode active material. In this constitution, assuming that a linear expansion coefficient K of felt turning in a radial direction and a circumferential direction in the structure body 3 is set in (K=3) or (K>3), the fact that linear expansion coefficients of the structure body 3 and the electrolyte tube 2 become the same speed when (K=3) is realized and the linear expansion coefficients become mutually separating speed when (K>3) is realized, can be proved. Thereby, the K is set in (K=3) or (K>3), and the sulfur 8 is melted when a battery temperature is raised, and a compressive condition of the felt is released, and the sulfur 8 is solidified when it is lowered, and the structure body 3 is contracted while increasing strength.

Title: Small-sized crystal vibrator
Inventor: OTSUKA MASARU
IPC: H03H9/19
Filed: 1987-11-11
Abstract: PURPOSE:To form a GT cut-off crystal vibrator at a high frequency band by adopting the electrodes arranged to both front/rear major planes of the vibration part as the arrangement of plural electrodes of five rows and five columns. CONSTITUTION:Electrodes 5a, 5b of five rows and five columns are arranged respectively to both front/rear major planes of the vibration section 1 and the electrodes 5a, 5b opposed between both the major planes and the electrodes 5a, 5b adjacent on one and same major plane are formed as opposite polarity. When an AC voltage is impressed to the electrodes, an AC electric field is generated between electrodes on the front and rear sides of the vibrator section. Since the AC electric field is applied oppositely between the adjacent electrodes, the expansion/contraction in the major planar direction of the vibration section due to piezoelectric effect is given inversely to the electrodes 5a, 5b. Since the 5th-order overtone is stimulated, a GT cut crystal vibrator at a high frequency band is obtained.

Title: Portable type semiconductor storage device
Inventor: KIMURA MASATOSHI
IPC: G06F12/16
Filed: 1989-11-02
Abstract: PURPOSE:To safely and easily change a main battery without erasing storage data by cutting off electrically an auxiliary battery, when a main battery holder is installed in a device body by a switch means, and connecting electrically the battery, when the holder is removed. CONSTITUTION:When a main battery holder 23a is drawn out of a frame 38 in order to change a main battery 23, a movable contact 42 of a rotary slide switch 40 rotates clockwise by a projecting part 47 of the main battery holder 23a, positioned on a fixed contact 43 and 44 and short-circuits them electrically. That is, the rotary slide switch 40 is turned on, and an auxiliary battery 37 is connected to a RAM. When the main battery 23 is changed and the main battery holder 23a in which a new main battery 23 is held is inserted into the frame 38 again, a positive pole and a negative pole of the main battery 23 come into contact with a fixed electrode terminal 26 and 27 and connected electrically. In such a way, a built-in battery can be changed safely and easily without erasing the storage data.

Title: Surface discharge luminous tube
Inventor: FUKUMITSU KENJI
IPC: H01J17/48
Filed: 1988-11-11
Abstract: PURPOSE:To make it possible to obtain the surface discharge light source having uniform brightness distribution by arranging the distance between individual adjoining anodes and that between each anode and cathode so as to be shorter than the length of the cathode dark space of a glow discharge. CONSTITUTION:The distance between individual adjoining anodes 241-24n and that between each anode 241-24n and a cathode 22 are arranged so as to have a shorter distance than the length of the cathode dark space of a glow discharge. When e.g., a helium gas is sealed in an airtight vessel 20 and a discharge is started between each anode 241-24n and a cathode 22 from the outside using a constant-voltage power source 29 and a current limitation resistance, each anode 241-24n becomes the region of a cathode 22 dark space by the condition of a stopping discharge. A negative glow part which is a luminous part converges on the whole surface where the light takeoff window of the anode exists, and is radiated from the whole surface of the light takeoff window of a surface-state airtight vessel. This makes a surface luminous body having the excellent uniformity of brightness distribution obtainable.

Title: Fuel electrode for fused carbonate fuel cell
Inventor: FURUKAWA SANEHIRO
IPC: H01M4/86
Filed: 1986-11-28
Abstract: PURPOSE:To prevent the deterioration of the cell characteristic by adding a chemically stable lanthanide rare earth metal to fused carbonate at the operating temperature. CONSTITUTION:Carbonyl nickel powder and metal lanthanum powder are mixed, the mixed powder is kneaded with a methyl cellulose aqueous solution into slurry, which is then molded into a sheet. The sheet thus obtained is dried and calcined in the air then sintered in the hydrogen atmosphere to form a fuel electrode 2. That is, a lanthanide rare earth metal is diffused in the fuel electrode 2 catalyst mainly made of nickel. Accordingly, the sintering and coagulation between nickel grains rarely proceeds during the cell operation, the gasification diameter and shape are stabilized for a long time, and the deterioration of the cell characteristic can be suppressed.

Title: Low-pitched sound stereo reproduction device
Inventor: HAYASE TORU
IPC: H04R1/34
Filed: 1989-10-31
Abstract: PURPOSE:To decrease the reproduction limit frequency by linking cabinets of 1st and 2nd channel reproduction devices and mounting a speaker transducing any channel signal of two channel signals into a sound wave to a link part. CONSTITUTION:When an L channel signal and an R channel signal are equal, since an L-R channel signal is 0, cone paper of a speaker 26 is not vibrated. When the L channel signal is alpha and the R channel signal is 0, a signal alpha is given to the speaker 26. The speaker 26 acts like excluding a back pressure of a speaker 24. Thus, the air layer at the back of the speaker 24 acts equivalently like a larger air layer than the air layer at the back of the speaker 25 and the air layer at the back of the speaker 24, the low frequency reproduction limit of the speaker 24 is expanded. Thus, when the volume of the cabinet is the same, the reproduction limit frequency is decreased.

Title: Scanning speed correction system for laser beam
Inventor: NAIKI TOSHIO
IPC: H04N1/04
Filed: 1988-11-11
Abstract: PURPOSE:To eliminate the need for the increase of the frequency of a reference clock so high and to correct scanning speed by varying the density of a control signal which turns on/off a laser beam as a scanning area moves from a center part to an end part. CONSTITUTION:The laser beam which is modulated based upon image information is deflected by a deflector 4 at a constant angular velocity and scanned on a recording medium 8. Then laser beam control signals with plural periods are generated so as to turn on/off the laser beam synchronously, and the density of the control signals is varied as the scanning area moves from the center part to the end part of a main scanning line 9. Consequently, variation in the scanning line on the main scanning line 9 due to the constant angular velocity scanning of the deflector 4 is corrected effectively. Consequently, the frequency of a reference clock is about 10 times as high as that which is normally used.
