Title: Device for controlling shifting of automatic transmission
Inventor: OTSUBO HIDEAKI
IPC: F16H61/06
Filed: 1988-05-25
Abstract: PURPOSE:To contrive to mitigate shock due to shifting by letting a lowering rate of hydraulic pressure to be supplied correspond to the type of a friction engaging device selected when shifting in an automatic transmission is in a final stage. CONSTITUTION:Hydraulic pressure to be supplied is controlled so as to let an engagement of a friction engaging device is selectively changed over so that shifting is automatically performed. A device is equipped with a judging means judging whether or not the shifting of an automatic transmission is in a final stage, and with a means which lowers hydraulic pressure to be supplied and makes a lowering rate one corresponding to the type of the friction engaging device to be selected when shifting is judged to have been in the final stage. Cushioning is therefore satisfactorily performed at the moment when the friction engagement device is finally engaged, that is, at the moment when change-over from the dynamic coefficient of friction to the static coefficient of friction is made in a large way, shock due to shifting can thereby be mitigated.

Title: Tape guide device
Inventor: SHISHIDO YUKINORI
IPC: G11B15/67
Filed: 1981-08-17
Abstract: PURPOSE:To prevent the generation of a permanently folded part on a magnetic tape at a failure in threading, by providing air blowout holes on a magnetic tape guide suface opposing to a vacuum column and putting the tape in the vacuum column through the blowout of air to the tape. CONSTITUTION:The supply of air to an air blowout hole 9 is stopped at first and a file 1 is rotated to lead off a magnetic tape for threading. The tip of tape reaches a machine reel while being introduced with a negative pressure formed with an air flow from an air blowout hole 8. During this operation, when the tip of magnetic tape arrives at the vicinity of a contact point between an outlet side air bearing 6 and a tape guide surface 7, air is blown out of the  hole 9. If the threading is failed and the tip of tape does not reaches the machine reel, excessive tape led off from the reel 1 suspends in a vacuum column  4 with the air flow blown out of the hole 9, thereby avoiding the formation of  an S- loop of tape in a winding body 2.

Title: Esd protective structure
Inventor: INIEWSKI KRIS
IPC: H01L27/02
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To enable the operation under usual operation voltage of an integrated circuit by allowing a resistance means to have a low resistance value, and controlling a silicon control rectifying element (SCR) so that it may break down at ESD voltage higher than low electrostatic breakdown(ESD) voltage, in the case that operation voltage is applied. SOLUTION: In the case that a circuit to be protected is not supplied with power, the gate of a first inverter is at ground potential. When the pad potential increases in positive direction, the reverse bias increases, which increases the width of a depletion layer, and the effective depth decreases. When the depletion layer of p-n junction increases, effective resistance width decreases. When the circuit to be protected is supplied with power, operation voltage is applied to it, and operation voltage is applied to the device of a pad. The voltage of a node VC is equal to the operation voltage VDD, and the voltage applied to p-n junction becomes nearly zero. The resistance of the device 27 has a low value, and the turn on voltage of SCR is high. Hereby, when applying operation voltage, usual circuit operation can be performed without causing breakdown.
