Title: Clad type lead acid battery of sealed structure
Inventor: MUKASA TOMONORI
IPC: H01M10/10
Filed: 1990-04-17
Abstract: PURPOSE:To suppress costs and prolong the lifetime of a battery by using a pos. electrode grating consisting of an alloy of Pb-Sb series, and filling the space between a pos. electrode plate and a neg. electrode plate with fine powder of a mixture of silica and titanium dioxide in a specific mix proportion. CONSTITUTION:5-15% fine powder of titanium dioxide is mixed with fine powder of silica as major component having excellent liquid absorptiveness, and the space between a pos. electrode plate and a neg. electrode plate and their surrounding are filled with this mixture. Therein the fine powder of titanium dioxide adsorbs the Sb, which is thus hindered from movement from the pos. to neg. electrode. This eliminates drop of the hydrogen over voltage because of Sb, so that the water decomposition will not increase, and there is no fear of impairing such features as being free from maintenance and water refilling. This enables fabricating an excellent lead acid storage battery of sealed type at a low cost.

Title: Manufacture of semiconductor laser
Inventor: MUROTANI TOSHIO
IPC: H01S5/00
Filed: 1979-08-06
Abstract: PURPOSE:To contrive the improvements in quantum efficiency of the semiconductor laser and the lifetime thereof by melting back a mesa structure with In solution without large deformation immediately before growing P type InP by liquid phase epitaxially on the surface of a smeiconductor crystal having mesa structure and removing the impurity on the surface and deformed layer thereon. CONSTITUTION:An N type InGaAsP 2, P type InP 3 and InGaAsP 8 are laminated on one main surface of an N type InP substrate 1. An SiO2 mask is coated thereon to form the mesa structure thereon, is contacted with In solution at 630 deg.C for approx. 1 sec. to melt back it. At this time Ga is dissolved in the In solution, and InP 3 is hardly etched not to deform the mesa structure. Then, an insulating layer 5 is coated thereon, and electrodes 6, 7 are attached thereto. Since the lateral enclosure layer of the active layer 3 is grown subsequently to the melt-back in this manner, there can be obtained a buried hetero structure having less defects to lower the oscillation threshold value and to increase the lifetime thereof in the laser.

Inventor: FUJITANI MASARU
IPC: G06M7/00
Filed: 1987-04-27
Abstract: PURPOSE:To accurately duplication of paper sheets always, even in case of existence of any unprinted portion on the paper sheets, by measuring transmitted light quantities at the plural positions of the paper sheets and comparing them with a standard value and judging it as duplication when duplication is detected even at one place. CONSTITUTION:A thickness detector 1 is provided to each of three places where the paper sheets are passed through an the thickness of an unprinted portion is detected by at least one thickness detector 1. On the other hand, a constant K is provided in a presetting device 4 in order to judge any duplication of paper money and is given to a comparing device 3. Thereat, an output signal S of each signal processing circuit 2 is compared with a judging constant K, and it is judged whether the signal S is smaller than the constant K. When the output signal S of at least one thickness detector 1 is smaller than the constant K, it is judged that two or more pieces of the paper money are overlapped. Therefore, overlapping can be surely detected, even though there are some unprinted portions (a water-mark) on the paper sheets.

Title: Power generation controller for generator-equipped vehicle
Inventor: TABATA ATSUSHI
IPC: B60L50/16
Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To attain efficient power generation according to generation requirements such as charging and the drive of auxiliary machinery, by generating electric power by means of a generator connected to an internal combustion engine through a communicator when it is determined that the generation of the generator disposed between power transmission systems to a driving wheel is not permitted. SOLUTION: When the charging condition of a battery is low, electric power is generated by a first motor generator 12 connected to an engine 3 through a communicator 11. On the other hand, when the charging condition of the battery is high, the electric power is generated by a second motor generator 4 connected to a power transmission system which transmits power to a rear wheel 1, that is, a driving wheel. When a vehicle is in a driven condition and large driving force is not required for start, electric power is supplied from the battery to the second motor generator 4 to start the vehicle. The second motor generator 4 serves as a motor at this time and cannot generate the electric power. Therefore, the first motor generator 12 can generate electric power.

CONSTITUTION: A turning side bearing washer 13 is fitted to a turning scroll member 11, and a fixed side bearing washer 15 is fitted to a fixed frame 12. A ball is rotated along a raceway groove 17. The turning side bearing washer 13 and the fixed side bearing washer 15 are eccentrically moved, and the quantity of eccentricity is two times the diameter of the pitch circle of the raceway groove 17. The washers 13, 15 are of the same shape, and small holes 16 for distributing the lubricant are pierced at appropriate intervals such as the equal intervals at a plurality of parts on the inner and outer circumferential sides on the circumference of the washers 13, 15. The small holes are formed in the center of the pitch circle of a plurality of raceway grooves 17 formed on the circumference of the ring-shaped bearing washers 13, 15.  Thus, more lubricant is distributed than the small holes for distributing the lubricant, and the fretting wear to be generated between a counter fitting member and the back surface of the bearing washer can be reduced.

Title: Sliding vane compressor
Inventor: TAYA TOSHINORI
IPC: F04C18/344
Filed: 1983-06-08
Abstract: PURPOSE:To prevent scuffing from being caused between a rotor and a housing, by forming an external shape of the rotor in a tapered shape so that one side end face may be formed in a diameter smaller by a very little amount than the diameter of the other side end face. CONSTITUTION:A rotor 3 is formed in a tapered shape in which its external faces are formed with one side end face 3a in diameter smaller by a very little amount than the diameter of the other side end face 3b. An angle alpha of this taper is set to a very little angle because this angle, if it is set to a very large degree, worsens a seal of external surfaces of the rotor 3. Accordingly, a space between one end side of the rotor and an internal surface 8a of a housing larger than the space between the other end side of the rotor and the internal surface 8a of the housing is provided. In this way, the one end side of the rotor 3 is never forced to be attached to the internal surface 8a of the housing even if a vane groove 2 is forced to be opened by a liquid refrigerant.

Abstract: PROBLEM TO BE SOLVED: To obtain a welding machine with which a set of inner-layer wiring boards are fixed by a method, wherein the set of inner-layer wiring boards whose prepregs are exposed on the surface are laid up and the prepregs are melted and welded by a welding head. SOLUTION: In this welding machine for an inner layer board, double-sided wiring boards and prepregs which constitute inner layers are placed alternately on a jig plate, so as to be laid up during the manufacturing process of a multilayer printed wiring board, several peripheral places are heated and pressurized spot-like, the prepregs are melted and welded, and constituent members for the inner layers are fixed temporarily. A tape 25 is arranged between the tip of a welding head 17, which heats and pressurizes the several peripheral places in the spot-like manner and a work 40, so that the welding head 17 does not come into direct contact with the prepreg in the surface of the work 40. The surface of prepregs are carbonized or softened to adhere to the tip of the welding head 17.  In addition, protrusion on the surface of the prepreg, formed by the tip of the welding head 17 is pressed by a stamper 27 so as to be leveled, and the lowering in the bonding strength of a copper foil on the surface is prevented. When the outermost layer is a double-sided wiring board, it is heated by the tip of the welding head 17 so as to be carbonized, and the use of the tape 25 is effective.
