Title: Genuineness discrimination system of banknotes
Inventor: KIDERA KINICHI
IPC: G07D7/16
Filed: 1978-04-21
Abstract: PURPOSE: To eliminate the disadvantage of becoming extremely long in the apparatus, miniaturize a bill checker, simplify constitution and achieve the improvement in reliability by using a detecting means of measuring the transmission quantity of light and a pulse generator in discriminating the lengths of banknotes.  
     CONSTITUTION: As a banknote is conveyed, transmission quantity sensors H1, H3 of light detect the banknote and the signal h is outputted from a waveform shaping circuit 21. Reading of the banknote pattern is then started and counting of the banknote length is accomplished in parallel with this. As H and L of the signal h of the circuit 21 are outputted, the pulse signals of a pulse generator 17 are counted with a counter 25 or counting is stopped and the pulse signals proportional to the conveying speed of the banknote are counted. This count value corresponds to the length of the banknote being conveyed. When the sensors H1, H3 make no longer detection, the count value of the counter 25 is compared in a comparator 28 and whether the banknote is within the range of its minimum and maximum values or not, i.e., the suitability of its length is judged in a control circuit 1 and memory circuit 2. A part of the position sensors may be saved and the reduced size, simplified constitution and improved reliability may be achieved.

Title: Ultrasonic motor and manufacture thereof
Inventor: KOMENO HIROSHI
IPC: H02N2/00
Filed: 1988-03-01
Abstract: PURPOSE:To suppress the generation of an audible sound by composing a vibration absorber layer between a moving element and a frictional material. CONSTITUTION:The vibrator of an ultrasonic motor is formed by adhering fixedly a vibrating element 2 of resilient material, such as metal or the like to the surface of a piezoelectric element 1. The moving element of the vibrator is formed by securing a frictional material 4 made of engineering plastic to the surface of a moving element 3 as a body through a vibration absorber layer 5, and bringing the surface of the material 4 into pressure contact with the surface of the element 2. Thus, a high frequency electric field of a resonance frequency is applied to the element 1 to generate a traveling wave of ultrasonic wave vibration at the elements 1 and 2. In this case, the moving element made of the material 4, the layer 5 and the element 3 in contact with each other at the traveling wave head of the element 2 is integrally driven by the frictional force with the element 2. An unnecessary vibration generated at the material 4 is absorbed by the layer 5, thereby suppressing the generation of an audible sound.

Title: Fluid machine of scroll type
Inventor: MORISHITA ETSUO
IPC: F01C1/02
Filed: 1983-03-22
Abstract: PURPOSE:To enable a clearance in the radial direction to be sealed without causing any necessity for using a counterweight, by equalizing a distance between centers of a crankshaft and an oscillating scroll shaft to the crank radius when the centers of the crankshaft, oscillating scroll shaft and an eccentric ring are arranged on a straight line by this order. CONSTITUTION:If a compressor is operated, a load is transmitted from an oscillating scroll shaft 4 to an eccentric ring 27, here mainly Fc of centrifugal force in the radial direction and a load Fg of gas compression force in the direction at a right angle with this load Fc are transmitted acting on a center O4 of the shaft 4. When the center O2 of a crankshaft 14, the center O4 of the shaft 4 and the center O5 of the ring 27 are placed on a straight line by this order, a distance O2O4 is substantially equal to a crank radius, consequently contact force (f) between an oscillating scroll 2 and a fixed scroll 1, being in little relation to the force Fc, becomes a function only of the force Fg. While the force Fg, being not changed by a change of rotary speed, is controlled to almost a fixed value. In this way, a clearance in the radial direction between the both scrolls 1, 2 can be sealed by utilizing the force Fg.

Title: Opening-sealing utensil for bag
Inventor: TAKEUCHI KIYOSHI
IPC: B65D33/16
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To re-seal an opened bag by a simple operation, and repeatedly perform the opening/closing of the bag by a method wherein two cylindrical members are engaged under a state wherein the two members may not interfere with each other, and the bag is pinched by utilizing the elasticity. SOLUTION: An opening 8 of a bag 7 is placed on the main body of an internal cylindrical member 1 in such a manner that the opening side may slightly remain, and two protruding parts 6 are pinched by fingers, and a force P is applied toward the inside. The diameter in the horizontal direction of the member 1 becomes smaller. When a force Q is applied while two protruding parts 5 of an external cylindrical member 2 are pinched with fingers, the diameter in the horizontal direction becomes larger. Since an interval on the internal end surfaces of a slit 3 is extended, the member 1 can be inserted in the member 2 without strongly rubbing the bag.  When the protruding parts 5 and 6 which are pinched with fingers are released, the bag 7 is pinched by the outer peripheral total surface of the member 1 and the inner peripheral total surface of the member 2 under a sealed state, and a high sealing property can be maintained. When this sealing utensil is removed, the bag becomes an opened state in the same manner.

Title: Safety device for optical medium recording/reproducing device
Inventor: SOMA TAKESHI
IPC: G11B7/004
Filed: 1989-02-28
Abstract: PURPOSE:To prevent a disk from being burned even when a microcomputer is troubled by supervising the relative moving speed between an optical medium and optical beams, and directly issuing a second laser beam shielding instruction to a laser driving circuit. CONSTITUTION:A disk rotating number of revolution detecting circuit 1 detects the transfer of a moving means, which relatively moves the optical beams and the optical medium, namely, the number of revolution of a spindle motor 8 to rotates a disk 5, and sends disk number of revolution information 1a to a disk number of revolution control circuit 2 and a disk number of revolution judgment instructing circuit 20. When the number of revolution of the disk, whose normal value is, for example, approximately 1,800rpm, reduces <= a designated value approximately 1,500rpm, the circuit 20 directly issues a second laser power source interrupting instruction to a laser driving circuit 3 to be one of the laser beam shielding means without using a microcomputer 11. Thus even when the microcomputer 11 is troubled, or a laser power source interrupting instruction 11a produced at a normal time is not issued, the disk 5 is not burned.

Title: Cleaning method for feed head part of killed steel ingot
Inventor: MATSUZAKI MINORU
IPC: B22D29/00
Filed: 1980-04-14
Abstract: PURPOSE:To make cleaning of feed head part thorough and considerably reduce the labor for taking care of the surface of a killed steel ingot by immersing the feed  head part of said steel ingot into water. CONSTITUTION:Water 4 is filled in a water tank 2, and a steel ingot 8 is hoised with the tongue arms 6 of a soaking pit crane of a soaking yard, thence only the feeder part of its head part is immersed in the water 4.
