Title: Semiconductor memeory device
Inventor: TAKEMAE YOSHIHIRO
IPC: H01L27/10
Filed: 1980-03-31
Abstract: PURPOSE: To facilitate reading operation by storing much charge in a memory cell by varying the potential of the capacitor electrode of the memory cell at proper timing and by obtaining a large potential difference on a bit line in the reading operation.  
     CONSTITUTION: After bit lines BL and -BL are charged up to V cc , word lines WL and DWL are held at V cc , so that the voltage drop across BL will be equal to that across -BL. Then, when -WL is held at V ss , a current further flows to N 1  and the voltage of BL drops further. The final voltage drop across bit line BL is shown by formula I. Therefore, BL and -BL have voltage difference C.V cc / (C+C β ). As word lines WL and DWL rise to V cc , the voltage drop across -BL is shown by formula X. On the other hand, the gate, drain and source of transistor Q of the memory cell are held at V cc , 2V cc -V th  and V cc , so BL and -BL have voltage difference C(V cc -V th )/(C+C β ) in this case. This voltage difference is greater by the amount of charge stored in the cell, showing that the amount of charge stored is sufficiently useful.

Title: Vane type compressor
Inventor: SHIBUYA TSUNENORI
IPC: F01C21/08
Filed: 1981-03-23
Abstract: PURPOSE:To enable to eliminate variation of the force acted to vanes by pressure in  back-pressure chambers, by forming a pressure-change compensating chamber having a  volume at least twice as large as the maximum total volume of the back-pressure  chambers in the manner that it is communicated to the back-pressure chambers, and  thereby absorbing change in the total volume of the back-pressure chambers. CONSTITUTION:Since vanes 4 are moved in respective slots 3 formed in a rotor 3 along  the inner surface 6a of a cylinder 6, the volumes of back-pressure chambers 18 are  changed with movement of the vanes 4. According to the present invention, however,  there is provided a pressure-change compensating chamber 23 having a volume at least twice as large as the maximum total volume of the back-pressure chambers 18, in the  manner that the chamber 23 is communicated to the back-pressure chambers 18. Therefore, the volume change of a space 25 of the chamber 23 is relatively small as compared with that of the back-pressure chambers 18, and the volume change of the back- pressure chambers 18 is absorbed by the chamber 23, so that the pressure change in  the space 25 itself is extremely small, and resultantly, the change of force acted to the  vanes 4 can be rendered extremely small. Therefore, it is enabled to change the number of vanes irrespective of the configuration of the inner surface 6a of the cylinder 6.

Title: Shielding device for laser welding
Inventor: AOKI HIDEKAZU
IPC: B23K26/12
Filed: 1981-03-25
Abstract: PURPOSE:To execute welding which has no defect in a weld part, high in its weld penetration efficiency and stable in its quality, by providing a low pressure a low pressure shielding chamber directly under a condensing lens, and forming a low pressure atmosphere. CONSTITUTION:Welding is performed by exhausting the inside of a low pressure shielding chamber 10 for welding, irradiating a laser beam 2a, and simultaneously moving a substance to be welded 5. Since the inside of the shielding chamber 10 is exhausted, the irradiated part of the laser beam 2a remains behind in a molten metal, and the atmosphere which causes generation of a defect or generation of oxidation of the surface does not exist. Also, to an inert gas shielding chamber 20, inert gas is supplied through a pipe 21 and a valve 22, therefore, even if leakage occurs between the substance to be welded 5 and a sealing part 13 due to sliding, there is no atmospheric air in the shileding chamber 10. Accordingly, since there is no air in a weld part, ozone is not generated, and welding without causing a defect is executed.

Title: Planer array antenna
Inventor: KURAMOTO AKIO
IPC: H01Q21/24
Filed: 1987-02-27
Abstract: PURPOSE:To obtain an antenna used in common as both orthogonal polarized wave and two-frequency with the size of the antenna by arranging a slot array with different resonance frequency orthogonally onto an intermediate conductor face and providing a microstrip line energizing the slot array to the conductor face of the upper/lower parts. CONSTITUTION:Microstrip lines 6, 7 are used as feeders to excite the slot arrays 2, 3 on the conductor plate 1 separately from the front and the rear sides to act the titled antenna radiating a polarized radio wave orthogonal thereto in a different frequency. In this case, since the feeders of two frequencies are provided separately from the front and rear sides of the conductor plate 1, the electric coupling of the feeders does not almost exist but is negligible. Moreover, the gain is nearly doubled by the presence of a reflection plate 8. The gain is maximized by selecting the distance between the reflection plate 8 and the conductor plate 1 to be nearly 1/4 wavelength of the operating frequency or its odd number of multiple of the wavelength.

Title: Video camera
Inventor: SEKIGUCHI HIRONOBU
IPC: H04N5/363
Filed: 1993-03-03
Abstract: PURPOSE:To always enable the stabilization of a luminance signal (Y signal) in the vicinity of a prescribed white level when sensitivity magnification varies in a camera for which the automatic setting of a high sensitivity switching is enabled. CONSTITUTION:The level of the luminance signal obtained from the output signal of a CCD 1 is compared with first and second reference values (the first reference value<second reference value), respectively, by comparators 6 and 8 and the period of the field shift pulse of a pulse for CCD drive is varied by the comparison result. Thus, means 14 to 16 varying the first and second reference values according to the output of a sensitivity switching circuit 5A are provided in a video camera which changes exposure time and is capable of switching sensitivity. In the process for which a video is dark and sensitivity is raised, the first reference value at the (-) terminal of the comparator 6 is also raised, and in the process for which the video is bright and sensitivity is lowered, the second reference value at the (+) terminal of the comparator 8 is also lowered. Thus, also when the sensitivity (exposure time) of the CCD varies, a Y signal becomes possible to be set to around a prescribed white level (for instance, a white 100% level).
