Patent JP-H04343034-A (JP)
Title: Semiconductor sensor
Inventor: ICHINOSE KATSUKI
IPC: G01D5/18
Filed: 1991-05-17
Abstract: PURPOSE:To enable a power consumption to be reduced and at the same time an output change at a leading edge to be reduced by reducing a voltage change which is applied to an area between a drain and a source or between a gate and the source at the time of waiting and reducing the drain current. CONSTITUTION:A voltage between a drain and a source is set to a same voltage as in the case of operation during waiting, a switch circuit 5 is turned on by an instruction from a control circuit 4, a division ration of resistance which is constituted of resistors R1-R3 is changed for reducing a potential of a gate G, and it is set to a voltage which is closer to a gate-source cur-off voltage which is a threshold value, thus substantially preventing a drain D current from flowing. Namely, the potentials at the drain D and a source S do not change, and the potential at the gate G changes only little. Then, when the potential of the gate D slightly increases in measurement state, namely at a leading edge, the drain D current increases rapidly and the subsequent current drift is extremely small, thus resulting in a stable state immediately.

Filed: 1990-05-31
Abstract: PURPOSE:To prevent the deviation, irregularity or omission of a transfer image from occurring and to prevent the quality of an image from being deteriorated by setting the downstream side in the carrying direction of a side being equivalent to the carrying surface of a transfer paper as a driving position and setting a surface being equivalent to the carrying surface as a loosing side. CONSTITUTION:An intermediate transfer body 6 is wound around a pair of rollers 6A and 6B and moved in the same direction as a photosensitive body 2 at a position where it is opposed to the body 2. Then, the roller 6A positioned on the downstream side of the carrying direction of the transfer paper S on the surface of a belt being equivalent to the carrying surface of the paper S is set as a roller on a driving side. Then, the surface of the belt being equivalent to the carrying surface of the paper S on the transfer body 6 is set on the loosing side and the surface of the belt being equivalent to the opposite side is set on a stretching side. Besides, a bias roll 11 is arranged at the opposed position to the roller 6A on the driving side on the transfer body 6 by interposing the transfer body 6. Therefore, the surface of the transfer paper on the belt being the intermediate transfer body is set under a state that it does not receive tensile, and the transfer image and a secondary toner image are integrally moved from a transfer position to a fixing position. Thus, the irregularity of transfer or the omission of the transfer image from occurring and the uniform transfer is realized.

Abstract: PROBLEM TO BE SOLVED: To process one SF card also as a coupon card (SR card) by performing prescribed discounting processing when the number of times of riding on a train for the same block reaches a prescribed number from a history of riding. SOLUTION: A print example printed through a punch print part P to the rear side of a card C shows a user holding the card C repeatedly rides on the train from a station A to a station B excepting riding from the station B to a station C on the second of July, and the user utilizes the card C mainly as coupons.

Namely, when riding in the same block (between the stations A and B) reaches the prescribed number of times (10 times, for example), a train fare in the same block is made free next time. Thus, until reaching the prescribed number of times, the prescribed train fare is subtracted and the card C is used as an ordinary SF card.
