Title: Semiconductor storage device
Inventor: MAEYAMA YOSHIKAZU
IPC: H01L27/10
Filed: 1989-03-01
Abstract: PURPOSE:To relieve a local stress given by a filler contained in a sealing resin when a pair of MOS transistors constituting a differential circuit of a sense amplifier is sealed with resin and to prevent unbalance of electric characteristics between the transistors caused by such stress by covering the transistor pair with a layer having a lower elastic coefficient than a surface protecting film. CONSTITUTION:An interconnection layer 5 formed of a material having a low elastic coefficient such as aluminum is laid out to cover a sense amplifier transistor region 3. If a stress is given to the surface of a chip on the sense amplifier by a filler contained in a sealing resin, the stress is relieved by the interconnection layer 5 having a low elastic coefficient. In this manner, it is possible to minimize variation in electric characteristics of the transistors caused by such stress and to decrease unbalance of electric characteristics between the transistor pair of the sense amplifier. Thus, it is possible to provide a sense amplifier having high sensitivity without altering the assembling processes of a semiconductor storage device.

Title: Modulator for antiskid brake control device
Inventor: KUSHIYAMA TAKASHI
IPC: B60T8/42
Filed: 1992-03-09
Abstract: PURPOSE:To prevent malfunction of the flow regulating valve of an antiskid brake control modulator on the brake cylinder side of larger capacity at ordinary service braking. CONSTITUTION:At ordinary service braking, because the capacity of a rear wheel brake cylinder 3B is smaller than the capacity of a front wheel brake cylinder 3A, the liquid pressure of the brake cylinder 3B is raised earlier. Brake liquid introduced to respective brake cylinders 3A, 3B presses downward the housings 6aA, 6aB of the flow regulating valves 6A, 6B on the front and rear wheel sides. But because the housing 6aB is fixed between a housing 5aB and a plug 32B, it is not moved downward even at rise of the liquid pressure of the brake cylinder 3B. Consequently, at service braking the liquid pressure of the chamber 19A of the flow regulating valve 6A is not influenced from the flow regulating valve 6B, and hence malfunction of the valve spool 6dA is surely prevented.

Abstract: PURPOSE:To detect an accurate displaced position of an electrified body in an electrostatic electroscope optically, by measuring the opening of the electrified body in the electroscope by means of the variation of bright and dark lines on a diffraction pattern. CONSTITUTION:When an ionization chamber 1 is irradiated by X-rays, pairs of ions generated in air in the ionization chamber 1 are collected in the electric field between an anode 8 and a cathode 9 to take away electric charge from an electroscope 2 and to close an electrified body. And when a laser beam 21 is irradiated on a diffraction grating attached to the electrified body to observe a diffracted beam 22, a diffraction pattern of the diffracted beam 22 can be observed depending upon the variation of the opened angle of the electrified body. By counting variations of bright and dark lines in the diffraction pattern with a photodetector 3, a closed angle of the electrified body, that is, an amount of ionization can be obtained to calculate the X-ray dose with a dose arithmetic circuit 7. Thereby the opening of the electrified body in the electrostatic electroscope can be measured by means of the variation of bright and dark lines in the diffraction pattern to obtain the displaced amount of the electrified body optically.

Title: Power source device for magnetic phase shifter
Inventor: KUROSAWA TOSHIAKI
IPC: H02M1/08
Filed: 1982-03-31
Abstract: PURPOSE:To obtain an output waveform which is sufficiently near a square  wave as a power source for a magnetic phase shifter by supplying the output  waveform of positive side from a DC power source by the switching operation  of a transistor. CONSTITUTION:When the resistor R side of a transformer T becomes positive, a base current flows through a transistor Q, which becomes ON. Then, a current flows from a DC power source ED through the collector and the emitter of the transistor, a square wave is generated across a resistor R0 and becomes an output E0. When the resistor R side of the transformer T becomes negative, the transistor Q becomes OFF, and the current from the power source E0 is shut off. However, the secondary side of the transformer T is conducted through a diode D8 with the output side. Accordingly, negative sinusoidal voltage is produced as the output E0. In this manner, when this operation is repeated, the output voltage E0 becomes a sinusoidal wave which flows in one direction (positive) and the other direction (negative).
