Title: Lock-up control unit for automatic lock-up change gear
Inventor: SUGA MASAAKI
IPC: F16H61/14
Filed: 1981-04-20
Abstract: PURPOSE:To prevent an engine failure by putting an engine into converter condition at the time of a sudden braking, that is, when after damping, a car velocity is below a set value which is higher than the velocity for releasing lock-up within the set time. CONSTITUTION:When a brake pedal is stepped upon during lock-up condition, a brake switch 10 is closed, and a brake signal SB is changed to a L-level in a time t1. The L-level signal is supplied to a NOR gate, and is inverted to a H- level in a NOT gate to be supplied to a condenser 14. The L-level signal is also supplied to the other input terminal of the NOR gate 15 only during the charging time T1 of the condenser 14, and the NOR gate 15 retains the brake retaining signal SB at a H-level only during T1. At a time t4 when the velocity is  lowered to a set value VB, a velocity, comparison circuit 9 sends out a L-level  signal from a gate d', so that a velocity comparison signal Sv rises, and a lock- up signal S1 is blocked in a AND gate 20.

Title: Method for chamfering glass member
Inventor: KOUNO KOUZOU
IPC: B23K26/38
Filed: 1989-03-13
Abstract: PURPOSE:To prevent generation of noise, deterioration of working environment and further, cracking and damage of a glass member by irradiating the glass member with a laser beam in the state with the whole of the glass member maintained at the prescribed temperature higher than the normal temperature. CONSTITUTION:In a first stage, the whole of the glass plate 1 to be chamfered is first heated gradually up to the prescribed temperature lower than its softening temperature and maintained at the prescribed temperature by using a heater, for instance. In a second stage, the glass plate 1 maintained at the prescribed temperature is then irradiated with the CO2 laser beam 2. At this time, while each corner part 1a of the glass plate 1 being irradiated with an irradiation spot 2a of the laser beam 2, the spot 2a is moved extending over the entire length, for instance of each corner part 1a along each corner part 1a. In addition, in a third stage, the whole of the glass plate 1 chamfered is heated by the heater and cooled gradually from a prescribed temperature and brought back up to the normal temperature. As a result, the corner parts 1a are softened and chamfered by heat and further, it is not necessary to abut any tool on the corner parts, hence the external force is not applied on the glass plate 1 and generation of noise, deterioration of working environment and further, generation of cracking on the glass plate 1 are prevented.

Title: Nonaqueous secondary cell
Inventor: TERASHI KAZUO
IPC: H01M10/05
Filed: 1987-03-16
Abstract: PURPOSE:To improve the cycle characteristic by pinching a metal plate alloyed with lithium with a pair of lithium plates as a negative electrode and forming the exposed section of the metal plate at the periphery. CONSTITUTION:An aluminum plate 2 is pinched and pressed by a pair of lithium plates 3, 3 with a size smaller than that of this aluminum plate 2, and the exposed section 2' of the aluminum plate is formed at the periphery as a negative electrode 1. A metal to be alloyed with lithium is selected from a group of aluminum, magnesium, zinc, tin, or lead for use. Thereby, the collapse and falling off of the periphery can be suppressed. As the charge and discharge cycle proceeds, the exposed section of the metal plate at the periphery is alloyed with lithium, but the falling off rarely occurs as compared with the case that the lithium alloy is used from the initial time. Accordingly, the charge and discharge cycle characteristic can be remarkably improved.

Title: Bias pattern of microwave circuit
Inventor: OODO HIDEKI
IPC: H01P1/00
Filed: 1984-03-30
Abstract: PURPOSE:To prevent unnecessary resonance and constitute a bias pattern which is stable in terms of high frequency by inserting an inductance circuit into the bias pattern and mounting a resistance element on the inductance. CONSTITUTION:The resistance element 51 is placed on the strip line 42 of the conventional inductance circuit 4 which is used to prevent unnecessary resonance and the both are connected in parallel to form a microwave inhibiting circuit 5, which is inserted into the bias pattern. At this time, the microwave inhibiting circuit 5 is a circuit damped in parallel by the inductance and resistance according to a lumped parameter, and attenuates unnecessary resonance. For example, when the line length of the bias pattern 6 is >=lambda/4, microwave inhibiting circuits 5 and 5 are inserted into the bias pattern 6 at an interval of <=lambda/4. Thus, the line length of the bias pattern 6 between the microwave inhibiting circuits 5 and 5 is set to <=lambda/4, thereby preventing the unnecessary resonance of the bias pattern 61 itself.

Then the pressure is applied from the side of layer 12 on the other surface to form split 16 toward the area where no groove 15 is formed, thus obtaining a number of light emitting elements 17 of a fixed size. In such way, no distortion is caused on PN junction surface 13 with no deterioration of the light emitting output. This method can also be applied effectively to the division of other semiconductor elements in addition to the light emitting element.

Abstract: PURPOSE:To firmly bond a disphragm and a current collector and to maintain the performance of a cell by forming the electrode contg. an electrode catalytic component and a thermoplastic rubber component into a film and pressure- welding the electrode to the solid electrolyte and collector. CONSTITUTION:A thermoplastic rubber excellent in corrosion resistance, e.g. a fluororubber, and an electrode catalytic component (or a carrier) are heated above the m.p. of the rubber and kneaded. The kneaded material is formed into a film-shaped electrode. The electrode is pressure-welded to a solid electrolyte and/or a current collector and integrated to obtain a cell structure of SPE type, etc. Since the electrode has good elasticity, the electrode is elastically deformed only by pressure-welding it to the diaphragm or collector, the adhesion between the welded surfaces is increased, and the performance of the cell, e.g. a decrease in resistance, is improved.
