Title: Vibration control device
Inventor: KOJIMA HIROSHI
IPC: F16F13/06
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of cracks of a sealing member due to the deterioration caused by ozone even when a device is used under the environmental condition of high ozone concentration. SOLUTION: An O ring 108 for sealing a space between a shield rivet 102 and a liquid charging port 100 is formed of a HNBR (hydrogenated nitrile rubber) having a high ozonic property. Because there is no double bond of carbon reacting with zone molecules in the HNBR, cracks due to the deterioration caused by ozone are not generated in the O ring 108 for a long period of time even when a device is used in an automobile engine room where the concentration of ozone is high, and thus leakage of liquid from a liquid chamber, caused by cracks of the O ring 108 can be positively prevented over a long period.

Title: Puckering in sewing of curtain and device therefor
Inventor: KATOU KANEKI
IPC: D05B35/08
Filed: 1994-12-05
Abstract: PURPOSE: To provide possibility of perpendicular intersection with the material to be sewn to produce a curtain without causing tumble or collapse of crests and/or bottoms by pinching the left and right ends of a pucker scale, slackening it so that puckers are formed, and processing the top of the material bit by bit so that crests and bottoms are generated in a certain specified proportion. CONSTITUTION: When puckers 1 consisting of crests 2 and bottoms 3 are formed and fed in sewing a curtain, the left and right ends of a pucker scale having a length required to form puckers 1 at the top of a curtain material 4 are pinched and moved toward the center for the same distance followed by slackening so that pucker formation is commenced.  At the same time, the top of the curtain material 4 is processed bit by bit in such a manner that at least the area between the left and right ends of the apex outer surface of each crest 2 is commenced later than the crest formation while at least the left and right ends of the inner surface of pucker 1 is lifted earlier than the movement and in a proportion of 3:1 relative to the distance between the left and right ends of the pucker scale so that crests 2 are generated and then depressed with a force weaker than the lifting force and until no margin is left any more for puckering so that bottom formation is completed.

Title: Self-cavity generating grinding stone made in resinoid bonding system
Inventor: KAWADA KENZO
IPC: B24D3/32
Filed: 1987-12-29
Abstract: PURPOSE:To improve the mechanical strength of a grinding stone body and to effectively cool the cutting edge or the grinding stone by arrangedly providing the grinding stone body made by mixedly kneading specific substance into a diamond segment on plural supporting bodies. CONSTITUTION:A grinding stone body 1 made by mixedly kneading water soluble granular substance such as granulated sugar or alum into a diamond segment is arrangedly provided on plural supporting bodies to form a desired self-cavity generating rinding stone. Since the water soluble substance contained in a part coming into contact with a cooling water on the grinding face of the grinding stone body 1 bissolves to leave a granular hole 3, where the cooling water collects, the cutting edge of the grinding stone body 1 is effectively cooled. In addition, a part not coming into contact with the cooling water of the grinding stone body 1 does not turn into a porous state, and the inside of the grinding stone body 1 is kept in a hollow nonporous state. Thus the mechanical strength of the grinding stone body 1 can be improved.

Title: Semiconductor integrated circuit device
Inventor: MIYAUCHI HIDETOSHI
IPC: G11C11/407
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To increase the working speed and to reduce the power consumption of a semiconductor integrated circuit device by converting the signal level corresponding to a 2nd voltage into an output signal level, corresponding to the 1st voltage or its nearby voltage and then converting the output signal level into a signal level corresponding to a 3rd voltage. SOLUTION: When a signal IN1 of a logic circuit LOG is at low level, a dropped voltage VPERI is applied between the gate and the source of a MOSFET Q23, and this Q23 is turned on and a MOSFET Q24 is turned off respectively. The drain potential of a MOSFET Q22 is set at a voltage corresponding to a power voltage VDD and turns off a MOSFET Q21 with an output signal OUT1 (IN2) set a high level respectively. A 2nd level conversion circuit converts an input signal IN2 into an output signal OUT2, having a level corresponding to a boosted voltage VPP. Then a signal level corresponding to the voltage VPERI is converted into the voltage VDD and then into the voltage VPP. Thus, working speed is increased, and power consumption is reduced for a semiconductor integrated circuit device.
