Title: Scroll compressor, revolving scroll used in the same and working method of the scroll
Inventor: TSUBOKAWA MASAHIRO
IPC: F01C17/06
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To prevent the concentration of stress to the jig pressure force by a key way by forming a pair of first key ways on a first diametral line at a back of an end plate of a revolving scroll, and forming a pair of second key ways on a second diametral line perpendicular to the first diametral line. SOLUTION: A compressor mechanism of a closed-type scroll compressor comprises a revolving scroll revolvable relative to a fixed scroll through an autorotation preventing mechanism using an Oldham ring. The oldham ring comprises keys directing perpendicularly to one another on the diametral lines on both surfaces, on this occasion, a pair of key ways 33, 33 slidably engageable with the key of the Oldham ring are formed on a diametral line X on the back of an end plate of the revolving scroll, and a pair of key ways 35, 35 are formed on a diametral line Y perpendicular to the diametral line X. Whereby the concentration of stress to the pressure force produced when the revolving scroll is fixed from an outer periphery of the end plate by a working jig can be dispersed in the working of the revolving scroll.

Title: Manufacture of laminated ceramic capacitor
Inventor: NARITA NAOTO
IPC: H01G4/12
Filed: 1990-01-26
Abstract: PURPOSE:To prevent a delamination, drop of the capacity by forming a ceramic green sheet having grooves, and employing a laminated body of the sheets obtained by filling an inner electrode material in the groove as a main part. CONSTITUTION:A ceramic green sheet immediately after coating is emitted with a microwave, and solidified and dried in extremely short time to obtain a ceramic green sheet 3. Reference symbols 3a, 3a,... are stripe grooves, each of which has 35mum of thickness to its bottom, 40mum of thickness to its upper surface, and 2.6mm of width. Then, conductive paste (inner electrode material) 4, 4,... are printed over the entire width of the entire width of the grooves 3a, 3b by screen printing to form an inner electrode film pattern. In this case, the surface of the dried conductive film is formed in the same plane as the upper surface of the grooves. The thus obtained sheet is cut in predetermined size. 29 sheets are superposed, and thermally press-bonded. Thus, since no sintering irregularity occurs, delamination and the drop of capacitance can be prevented.

Title: Semiconductor memory device
Inventor: KOMURO TOSHIO
IPC: G11C11/407
Filed: 1990-01-25
Abstract: PURPOSE:To shorten time required for the high potential side of a bit line to reach reference voltage by providing a transistor (TR) between a sense amplifier drive line and external power supply, and controlling the turning-ON/OFF of the TR by a sense amplifier activation signal and the output signal of a differential amplification circuit. CONSTITUTION:When the sense amplifier activation signal phiS becomes a high level, the output of a NAND circuit 13 becomes a low level, and the TR Q1 is turned ON, and power is supplied immediately to the sense amplifier drive line SAP from primary power supply VCC, and the potential rises. When the potential of the SAP rises and exceeds the reference voltage VREF, the output of the differential amplifier 11 becomes the high level, and the output of the circuit 13 becomes the high level, and the TR Q1 is turned OFF. Thus, the drain of the TR Q1 and the internal supply voltage VINT of the voltage of the SAP become nearly equal to the reference voltage VREF. Accordingly, the time required for the potential of the SAP and the high potential side of the bit line to reach the reference voltage can be shortened.
