Title: Capacitor voltage impressing circuit of memory cell in semiconductor storage device
Inventor: OGURA ISAO
IPC: G11C29/50
Filed: 1983-11-09
Abstract: PURPOSE:To attain screening effectively with high efficiency while the advantage that the operation of a memory cell is hardly affected by the instantaneous fluctuation of the operating power supply is kept by providing a switching circuit for screening to a common connecting point of each MOS capacitor. CONSTITUTION:A transistor (TR) 7 is turned on and a TR8 is turned off at normal operation in an LSI memory and a low voltage VCP is impressed to one electrode (electrode on an oxide film) 26 of each MOS capacitor 3 of the memory cells 1... through the TR7. Thus, no deterioration or breakdown is caused to a thin oxide film 24 of the MOS capacitor 3, and since a voltage Vcc is not directly impressed to the MOS capacitor 3 even if a momentary fluctuation of the operating power supply voltage Vcc is caused, the operation of the memory cell 1... is hardly affected. While the TR7 is turned off and the TR8 is turned on during screening, the voltage Vcc is impressed to each MOS capacitor 3 through the TR8.

Title: Semiconductor storage device
Inventor: TSUJIMOTO JUNICHI
IPC: G11C16/04
Filed: 1985-09-24
Abstract: PURPOSE:To extremely shorten a time required for erasing and writing the whole chips in an EEPROM by connecting a capacitor 12 between two terminals of an EEPROM cell to which a high voltage is applied at erasing/writing through a resistor. CONSTITUTION:A high voltage is applied between nodes 6, 7, a word line 5 is selected to charge the capacitor 12 electrically and to keep the potential difference between both the terminals of the capacitor 12, and then the word line 15 is closed. Since the resistor 11 exists, the potential difference between the drain 3 and the control gate 1 of a MOSFET is reduced less than the potential difference of the capacitor 12 by CR delay, so that a thin oxide passing a tunnel current can be prevented from the application of stress. The opening time of the word line 5 may be sufficiently satisfied with the charging time of the capacitor 12.

Title: Burning jig
Inventor: MANO TOSHIMASA
IPC: C04B41/87
Filed: 1994-08-10
Abstract: PURPOSE:To stably use a burning jig without generating cracks or peeling on a coated layer even in use for a long period by adding and including a specific quantity of magnesia into calcia-stabilized zirconia as the coated layer. CONSTITUTION:Since calcia-stabilizig zirconia must be inactive in order to maintain a nonreactivity with a material to be burnt, it is temporarily molten by an arc discharge method, then, the obtained product is cooled and solidified, and, thus, electromelting zirconia obtained by grinding the resultant product is preferably used. Calcia-stabilized zirconia whose stability is 15% or higher is preferably used. The amount of addition of magnesia may be 0.5 weight % or more. The upper limit of the amount of addition can be arbitrarily set depending on the kind of the material to be burnt. In this case, since magnesia generates a hydration reaction to prevent dispersibility to water, the amount of addition thereof may be preferably 10wt.% or less. Thus, a burning jig can be stably used without generating cracks or peeling on a coated layer even when it is used for a long period.

Abstract: PURPOSE:To produce the titled metallic bumps at low cost by a method wherein an Si substrate is utilized for the substrate whereon bumps are provided, SiO2 are utilized for semipermanent plating masks while metal films are buried in plating region to provide metallic bumps. CONSTITUTION:SiO2 films 31, 31' are laminated on an Si substrate 30 while films 31 are provided with resist masks 32' and then openings 33. Films 34 made of Ti-Pd or Ni etc. are evaporated. The masks 32' are removed and the substrate 30 is utilized for one electrode to form Au bumps 35 on the films 34. Next metal leads 36 with the same intervals as those of the bumps 35 are aligned with one another to be pressurized by a jig 37 heated up to around 500 deg.C. When the leads 36 are made of Sn plated Cu, the bumps 35 and the leads 36 are junctioned using Au.Sn alloy and when the jig 37 is removed, the metallic bumps 35 may be easily peeled off from the metal film 34 on the substrate 30.

Title: Storage time controlling circuit for focus detecting device
Inventor: KAWAMURA MASAHARU
IPC: G02B7/28
Filed: 1982-12-01
Abstract: PURPOSE:To reduce a storage time so that a focus detecting operation can be executed more quickly, in case when an illumination is executed by an artificial light, by providing a storage time mediating means for shortening a time when an integral output reaches a reference level, and operating the means when an auxiliary light is used. CONSTITUTION:An output of an AND gate A15 operates as a shift pulse phiT of sensors 15, 16, and when phiT becomes Lo, the sensors 15, 16 display a storage opration of an image pattern whose image is formed. Also, in this case, a transistor TR becomes off by a Q output Lo of an FF2, therefore, a capacitor C starts charging of an output current of a photodetector PD. When charging to the capacitor C is started as mentioned above, and its charging level reaches a reference level determined by resistances R2, R3 and R1, a comparator CP1 outputs Hi. As a result, Q of the FF2 becomes Hi from Lo. Therefore, an AND gate A15 sets its output phiT to Hi again, and sends out charge accumulated by the sensors 15, 16 to an analog shift register in the sensor. Accordingly, a level of an image pattern signal accumulated by the sensor is amplified and mediated automatically to a proper level, irrespective of a photographic luminance.

Title: Elliptic raceway rolling bearing
Inventor: HONDA TOSHIO
IPC: F16H55/38
Filed: 1985-09-26
Abstract: PURPOSE:To reduce friction torque at the time of rotation as well as to decrease the extent of wear, by installing a pocket part in a retainer holding a ball rolling between both inner and outer rings and lessening a degree of play in the retainer at a short race position of a rolling bearing. CONSTITUTION:With rotation of an inner ring 4a, a rolling position of a ball 4c comes to move as repeating a long race position and a short race position alternately. At this time, a narrow part 4f of a pocket 4e in a retainer 4d comes close to the ball 4c, restricting this ball 4c. Accordingly, the retainer 4d will not come into contact with the inner surface of an outer ring 4b on the short race,and further the inside surface rotates without contacting an outer surface of the inner ring 4a. Next, the ball 4c on the long race comes into a state of being floated from the pocket 4e because the retainer 4d is true roundness in form. Therefore, the retainer 4d is regulated of its play in both long and short race directions, thus it is in no case contacted with both inner and outer rings.
