Title: Cmos transistor structure
Inventor: TAKADA KAORI
IPC: H01L29/78
Filed: 1989-08-21
Abstract: PURPOSE:To prevent a transistor from being broker in the N-channel transistor constructed by a CMOS process by constructing the transistor in such a way that no P<+>-type area is provided in the vicinity of a boundary between a gate and a field, and the outside of the field. CONSTITUTION:Carrier production is reduced and junction breakdown is prevented by a method wherein there is no junction surface formed between an N-type diffusion area where a hot carrier is liable to be produced and a P<+>-type isolation area. There are formed ordinarily a gate 1, a drain side N<->- type area 2A, a source side N<->-type area 2B, a source side N<->-type area 2B, a drain side N<+>-type area 3A, a P<+>-type isolation area 4. Assuming a situation that the gate 1 and the area 3B are connected to GND, and voltage near the limit of withstand voltage is applied to the area 3A, back bias is applied to a PN junction between the area 2A and the P-type area 5 by the present method. Accordingly, carrier is unlikely to be produced without causing excess current compared with a conventional case where P<+> and N<-> are joined.

Title: Intermittent driving circuit
Inventor: TANI TETSUYA
IPC: G11B15/467
Filed: 1982-12-07
Abstract: PURPOSE:To always attain a noiseless still and slow motion reproduction by providing a phase comparing means between an RF switching pulse and a reproduced control signal, and controlling singly or in combination the generating timing and width of both starting and damping pulses, respectively. CONSTITUTION:A trapezoidal wave producing circuit supplies an RF switching pulse A and produces a trapezoidal wave like B. The wave B is sampled by a reproduced control signal D at a phase comparator 15, and the holding output E is supplied to a time constant control circuit 16. The circuit 16 consists of a pnp transistor TR5. Then the emitter is connected to the joint of a resistance R and a variable resistance VR of a time constant circuit 17 comprising the resistance R, the resistance VR and a capacitor C. At the same time, the phase comparison output is connected to the base. Therefore, the larger the phase difference between the RF switching pulse and the reproduced control signal, the smaller the holding output. Thus the charging time of the capacitor C increases, and the generating timing of the damping pulse is delayed.

Abstract: PURPOSE:To efficiently cool the fluid to be cooled, by providing one pair of electric-conductive plates that are connected with the same type of Peltier elements and arranged at a certain distance, and by furnishing a cooling fluid path on one end of the plates, and a flow path for the fluid to be cooled on the other end. CONSTITUTION:When direct current is applied to Peltier elements, N-type element 3 releases heat at + side and absorbs heat at - wide, and P-type element 4 absorbs heat at - side and releases heat at + side. As both the elements 3 and 4 are connected so that the up sides are + side, and down sides are -side, both the elements 3 and 4 absorb heat at the compressed air flow path 12 side and release heat at the ram air flow path 11 side. Therefore, as the compressed air is cooled by the ram air that flows between the elements 3 or the elements 4 arranged in element arrangement parts 2, and simultaneously cooled by both the elements 3 and 4, the compressed air is efficiently cooled even when a large amount of low temperature ram air is not available.
