Abstract: PURPOSE: To let a motor run at the same instant when a mode selection button is depressed by providing a means of running the motor based on the driving signal of a plunger driving circuit at the time of mode changing-over other than stopping and a means of supplying voltage to a servo circuit.  
     CONSTITUTION: A motor driving circuit 530 is constituted by a constant current circuit 533 consisting of a transistor Tr 532, a driving Tr 534, a rotating number detecting frequency generator 535 for servo, etc. When the selection button is pushed from stop mode to other mode, the Tr 538 goes ON approximately simultaneosly and therefore the Tr 534 of the circuit 530 turns ON to run a motor 531 immediately, by the torque whereof mode changing-over is accomplished. At the same time, a voltage is applied to the circuit 533 via cam gear position detecting switch 90 to charge a capacitor 537 and therefore the motor 531 keeps running even after energizing of a plunger 3 is finished. When the mode changeover operation is finished, a set detection switch 92 applies a voltage. this enables the motor to be run at the same instant when the mode selection button is depressed.

Abstract: PROBLEM TO BE SOLVED: To identify a printed sheet of a bank note or the like by providing a detection means for sensing fluorescence outputted from the sheet irradiated by ultraviolet light and detecting that the output of a sensing means becomes larger than a reference value which is previously set. SOLUTION: The received bank note 36 individually passes through a feed path 30 by a bank note transportation means.

The output of the optical diode 40 is detected to be larger than the reference value which is previously set. Since a forged bank note formed of paper whose material is tree emits fluorescence when it is exposed to ultraviolet light, the bank note 36 is shown to be valid or not by using output obtained from the optical diode 40. When the bank note 36 is valid, it is sent to a collection means 44. When it is not valid and is refused, it is sent to a refusal container 48.

Filed: 1986-06-16
Abstract: PURPOSE:To improve a signal-to-noise ratio by placing two thin film recording and reproducing elements in positions which become on the same track, so that a gap of these elements has an azimuth having a prescribed relative angle to each other. CONSTITUTION:On a slider 2, a Cu film of 3mum is formed in the lower half of coils 4, 5, and thereafter, an Al2O3 film of 0.5mum is formed on the lower half of the coils 4, 5. In order to form a magnetic pole 6 and 9 on this Al2O3 film, a 'Permalloy(R)' film whose film thickness is 10mum is formed, and gaps 7, 8 are etched obliquely (angle 45 deg.), respectively. In this way, gap directions of two recording and reproducing elements are different by 90 deg.. Accordingly, directions of a magnetizing transition, which have been recorded in adjacent tracks have an angle of 90 deg. each other, therefore, at the time of reproducing a data signal of each track, the data of the adjacent tracks are not reproduced. Therefore, a guard band between the adjacent tracks can be set to '0', and the signal-to-noise ratio can be improved.

Title: Optical temperature sensor
Inventor: IEDA TOMOAKI
IPC: G01K11/12
Filed: 1986-06-17
Abstract: PURPOSE:To obtain a temperature sensor consisting of a small number of components by pressing up an optical fiber directly by part of shape memory alloy and also using a two-directional coil spring. CONSTITUTION:An optical fiber 11b is fixed in a V groove 12 and a fiber 11a is pressed into the groove 12 near its tip by a leaf spring 16. Then, one terminal of torsional coil spring type two-directional shape memory alloy 15 is fixed to a main body 1 and the other terminal pressure the optical fiber 11a against the leaf spring 16 above certain temperature. Consequently, the terminal of the alloy 15 which is not fixed does not contact the optical fibers at the room temperature, so the fiber 11a is pressed into the V groove 12 by the spring 16 and the optical axes of the fibers 11a and 11b are aligned with each other. The alloy 15 is to change its shape above the certain temperature and pressure up the tip of the fiber 11a and the spring 16, so that the optical axes of the fibers 11a and 11b are not aligned any more with each other. Thus, light in the fibers 11a and 11b is transmitted and intercepted about the certain temperature.
