Title: Capacitor and manufacture thereof
Inventor: MIYAZAKI MASAHIRO
IPC: H01G4/12
Filed: 1989-06-22
Abstract: PURPOSE:To easily manufacture a capacitor having high withstand voltage and large capacitance by piling up Si substrates respectively provided with silicon-oxide layers on both surfaces upon another with internal electrodes in between and, at the same time, forming gap spaces on one sides of the electrodes. CONSTITUTION:After dielectric films 6 are formed of a silicon oxide on upper and lower surfaces of a plurality of Si substrates 4, the substrates 4 are piled up upon another with internal electrodes 8 in between and one end face of each Si substrate 4 is coated with insulating members 10. The first external electrode 14 is connected to the end faces of the electrodes 8 on which the members 10 are formed and the second external electrode 16 is connected to the end faces of the substrates 4 opposite to the members 10. Then gap spaces 9 are formed between the electrode 16 and end faces of the electrodes 8. The silicon oxide forming the dielectric films 6 is compact and high in withstand voltage, the withstand voltage of the films 6 is improved. Moreover, since the substrates 4 are piled up, the capacitance of this capacitor is multiplied and, since the gap spaces 9 are formed on one sides of the electrodes 8, the electrode connecting process can be carried out easily. Therefore, a capacitor having large capacitance and high withstand voltage can be manufactured easily.

Title: Window type air conditioner
Inventor: INOUE OSAMU
IPC: F24F13/20
Filed: 1984-07-30
Abstract: PURPOSE:To prevent rainwater from flying to a heat generating parts and to improve reliability, by a method wherein the heat generating parts, with which an inverter is formed, are located to the indoor side of a fan casing. CONSTITUTION:During heating operation, heat is exchanged by an indoor side heat exchanger 13, and hot air is blown in a chamber through a supply port 24 with the aid of an indoor side blast fan 12. A part 16 for controlling an inverter is attached to the indoor side 6 of a fan casing 5 through a mounting sheet 15, and is located, facing an air flow passage 14, and thereby the part is positively cooled by means of an indoor air passing through the air flow passage 14. Meanwhile, during cooling operation, a cooling air is blown in with the aid of the blast fan 12. In which case, the cooling air is heated by a radiation heat from the part 16 from controlling the inverter, but since cooling operation is decreased in an operation load of a freezing cycle over that of heating operation it has a surplus in terms of capacity. A cooling load is set to a slightly higher value in consideration of a radiation heat from the part 16 for controlling the inverter, and this enables production of comfortable cooling sensation with high efficiency.

Title: Semiconductor memory
Inventor: TOMIGAMI KENJI
IPC: G11C11/409
Filed: 1990-06-19
Abstract: PURPOSE:To enlarge potential difference between paired I/O lines and paired bit lines to be connected by composing the semiconductor memory of an inverter, which is controlled by a signal to be generated from a column decoder, and a P-Ch transistor. CONSTITUTION:Just after a gate control signal CY9 is made H, a transistor Tr (T12) is turned ON and charging is started from a bit line side Vcc to be made H. Namely, the paired bit lines to be selected by the column decoder are charged by a separate bus in addition to a P-Ch sense amplifier. Therefore, when the gate control signal CY9 is turned to an H level, the potential difference between the paired bit lines is enlarged. Afterwards, the potential difference between paired I/O lines 7 and 8 to be connected is enlarged as well. On the other hand, since the paired bit lines not to be selected excepting for paired bit lines 3 and 4 to be selected are comparatively slowly charged while being divided, a peak current is not changed.

Title: Foamed resin pattern for mold
Inventor: TSUNODA HIDEO
IPC: B22C7/02
Filed: 1978-12-28
Abstract: PURPOSE:To prevent the blow-back of molten metal and the formation of blowholes by constituting the pattern by the molding having continuous vent holes among foamed resin particles thereby letting the gas evolved by pouring through the continuous vent holes. CONSTITUTION:A binder solution is compounded in foamed resin particles 1 having closed cells, whereby a binder layer 2 is evenly formed on the surfaces of the resin particles 1. Next, these are packed in the specified mold and hot air is sent into the mold, at the same instant of which the mold is pressed. When the foamed resin particles 1 are partially bonded and the temperature has lowered to the deformation temperature or lower of the binder layer 2, the mold is parted. This yields the pattern of good air permeability having the continuous cells 3. Hence, the combustion gas evolved through pouring passes through the cells 3 and is discharged to outside the mold, thus its stagnation in the mold is obviated.

Title: Flexible shaft coupling
Inventor: MATSUBARA YUTAKA
IPC: F16D3/68
Filed: 1981-10-08
Abstract: PURPOSE:To aim at a decrease in the internal stress and abrasion as well as prevention of vibrations of an elastic member in time of setting an angle of deflection, by setting up the plural number of elastic members or plurally divided elastic members that are disposed in the direction of a rotary shaft, between each of coupling twins attached to a pair of rotary shafts. CONSTITUTION:Turning torque of a rotary shaft 11 is transmitted to another rotary shaft 10 via a coupling twin 13, engagement claws 20, elastic members 17 and 18, linkage projections 16 and a coupling twin 12. In the case where rotary shafts 10 and 11 are deflected with a deflection angle value alpha, since the elastic members 17 and 18 are in the state of being divided into two parts in the axial direction through grooves 17b and 18b, internal stress is theoretically decreased to about one fourth with the monolithic construction whereby abrasion of each elastic member is thus lessened. Simultaneously vibrations in operation is as well decreased. With this constitution, the prolongation of service life and prevention against vibrations in every elastic member can be much expected.

Filed: 1988-06-28
Abstract: PURPOSE:To prevent blur of color by outputting a sampling clock D/A- converting three signals, R-Y, B-Y, Y simultaneously at the changeover of a frame data and a slave screen video signal from picture-in-picture. CONSTITUTION:When a picture-in-picture memory 2 outputs respectively a frame data and a slave screen video signal, the phase of the leading of a sampling clock 3 of a D/A converter 40 of the R-Y, B-Y and Y signals is deviated the same as a conventional system. However, a color blur correction circuit 30 matches the leading phase of the sampling clock 3 of the D/A converter 40 of the signals R-Y, B-Y, Y at the switching of the frame data and the slave pattern video signal. Thus, the switching of the output signal 5 of the D/A converter 40 is outputted without mixed signal and the effect of preventing blur of color is attained.
