Title: Commodity transporting mechanism protection device for automatic vending machine
Inventor: MATSUGAMI MAKOTO
IPC: G07F9/00
Filed: 1989-02-13
Abstract: PURPOSE:To prevent a motor or a transporting mechanism from being damaged by outputting an overcurrent detection signal when the driving current of the motor to operate the transporting mechanism is more than a set value and stopping the supply of the driving current when a current supplying means detects the overcurrent detection signal. CONSTITUTION:When a commodity is clogged, the motion of a transporting mechanism 16 and the rotation of a motor 18 are stopped and a driving current I more than a rated value flows, the driving current I is compared with the set value when the driving current I of an overcurrent more than the rated value is inputted to a comparator circuit 6. Here, since the driving current I is more than the set value, an overcurrent detection signal J is outputted to a current supplying means 4 of the motor 18. By the output, the supply of the driving current I is stopped and the rotation of the motor 18 is stopped. Thus, the motor or transporting mechanism is not damaged.

Title: Flow rate controller for power steering
Inventor: KOMAMURA SEIJI
IPC: B62D5/07
Filed: 1982-03-05
Abstract: PURPOSE:To secure the high-speed steering stability with a large or small opening of an orifice at a low speed or high-speed position by enabling the movement of a partition having a through hole for the variable orifice depending on the position of a transmission gear. CONSTITUTION:With the gear of a transmission at the first speed position, a control circuit 27 fails to excite a solenoid 21 and a mobile cylinder 22 is pushed to the engaged position with a snap ring 25 by means of spring 26 and a head 7B of a drooping pin 7 of a spool 6 runs through the through hole 9 of the partition 20 to a large extend. This checks reduction in the effective area of a variable orifice 10 even when the spool 6 moves to open a bypass port 4 with an increase in the flow from a pump port 2 thereby positively preventing the shortage of the power assist during the climbing of a hill. On the other hand, at the position of a high speed such as fifth speed, the solenoid is excited to the maximum thereof by a signal of a gear position detecting means 28 to bring the head 7B closer to the partition 20 in the initial position and thus as the spool 6 begins to open the bypass port 4, the supply flow to a power steering is reduced to secure the high-speed steering stability.

Title: Driving method for solid-state image pickup device
Inventor: HARADA NOZOMI
IPC: H04N5/335
Filed: 1986-02-19
Abstract: PURPOSE:To make sensitivity adjustment possible by shifting time of pulse operation that injects bias charge to a photo-conductive film and pulse operation that removes a part of injected bias charge to the photo-conductive film side to transferring operation of signal change to a signal change accumulating section without changing time relation of the two operations. CONSTITUTION:Sensitivity adjustment of an image pickup element is made by changing relative position of the first and second voltage pulses phiB, phiTG in vertical effective term TVE keeping time relation of phiB, phiTG constant. That is, a term from pulse operations of injection and removal of bias charge by the first and second voltage pulses phiB, phiTG to next field shift pulse becomes a term of effective signal change accumulation, i.e. an effective sensitivity term. Consequently, remaining excessive charge of charge caught at a trap level in a photo-conductive film by bias charge injection can be removed similarly even when the length of effective sensitivity term is changed. By this bias charge injection, a photo-conductive residual image caused by trap level in the photo-conductive film and a capacity residual image caused by discharge phenomenon of capacity including the photo-conductive film are reduced.

Filed: 1989-02-14
Abstract: PURPOSE:To preclude out-of-focus photography by discriminating whether or not a current subject is an object of distance measurement which causes distance mismeasurement with the output of a displacement quantity calculating means. CONSTITUTION:Light receiving means 5 and 6 detect the incidence position of a projection reflection image on the subject in two dimensions and the range finder has a subject information calculating means 3 which calculates subject distance information from the output of a light receiving means 1 parallel to the base line direction and the displacement quantity calculating means 4 which calculates the quantity of displacement of the center of gravity of the projection reflection image at right angles to the base line direction from the output of the photodetecting means in the direction perpendicular to the base line. Then it is discriminated whether the current subject is an object of distance measurement which causes distance mismeasurement with the output of the displacement quantity calculating means 4. When so, a discrimination means 81 generates a warning. Consequently, a photographer is informed that a proper distance measurement result is not obtained in such a case and out-of-focus photography is precluded.
