Abstract: PURPOSE:To set the condition of forming the optimum image by arranging a first electrode with the length almost the same as the width of an object to be measured in parallel near the body being measured to measure the potential with respect to a second electrode connected electrically to the first electrode. CONSTITUTION:A linear electrode 8 is arranged entirely on the length of a photosensitive body 6, namely, on almost the entire width of a manuscript.

Title: Casting mold molding method
Inventor: NAKADA KUNII
IPC: B22C9/02
Filed: 1978-07-01
Abstract: PURPOSE: To drastically reduce the set time of conventional paste casting molds by filling the refrigerated casting sand having been refrigerated while kneading the specific binder into a preheated mold then drying the same to set, in molding the casting mold.  
     CONSTITUTION: 100 parts of No.6 silica sand, 2 parts of dextrin and 0.5 part of powder phenolic resin are kneaded for 5 minutes with a sand mill. While the mixture is being stirred with a mixer, liquified N 2  gas is supplied to make refrigerated  sand grains, which are then instantaneously filled in a circular core box mold having been preheated to 300°C by blowing. After 1 minute, the mold is turned over  and is released, whereby the hollow core is obtained. By using this hollow core, cast  iron is poured, whereby the good casting is obtained. The disintegrating characteristic of the hollow core is good and the addition of the phenolic resin is for improving  the strength of the core. As a result, the set time of the paste casting mold which  had hitherto required 8 hours is reduced to about 1 minute. Perfect reuse of the  waste sand is also possible.

Abstract: PROBLEM TO BE SOLVED: To prevent vibration of a governor rope by providing an earthquake detection part and a frame which is provided in a hoistway, moves to the side of a governor rope, when an earthquake is detected by the earthquake detector, and surrounds the governor rope. SOLUTION: A frame 11 is rotatably attached to a wall part of a hoistway 1 via a spring hinge 12 for attachment. An electromagnet 13 is provided on the wall part of the hoistway 1 so as to attract the frame 11. When an earthquake occurs and excitation of the electromagnet 13 is released by a control part 16 based on a detection signal of an earthquake detection part 15, the frame 11 is rotated by the spring force of the spring hinge 12 for attachment. On the way of its rotating, a stopper 11c is pushed by a governor rope 4 so as to rotate inward of the frame main body 11a, however, when the governor rope 4 enters completely inside the frame main body 11a, it is returned to its original place by the spring force of the spring hinge 11b for stopper. The part of the governor rope 4 connected to a car 2 is thus surrounded with the frame 11 from the four sides.

Filed: 1980-06-12
Abstract: PURPOSE:To make distribution and mixing of light bidirectionally among four pieces of optical fibers possible by using four pieces of reflecting mirrors of a columnar shape of a rectangular equilateral triangle. CONSTITUTION:The light transmitted in an optical fiber 12 disperses at a pi/2 cut cylindrical type focusing lens 16, and emits from its optical output face as parallel rays. Roughly one third of the parallel rays is reflected by a reflecting mirror 20,  and is made incident to a pi/2 cut cylindrical focusing lens 15, and the remaining  one third is reflected by a reflecting mirror 21 and is made incident to a pi/2 cut cylindrical focusing lens 17. Roughly one third the remaining parallel rays goes  through the space created between the mirrors 20 and 21 and the mirrors 19, and  22 and is made incident to a pi/2 cut cylindrical focusing lens 18. Hence, the light propagating in the fiber 12 is uniformly distributed to optical fibers 11, 13, 14. The  same holds true of the light propagating in the fiber 11, 13 or 14.

Abstract: PURPOSE:To attain dubbing at a standard speed even when a dubbing speed changing-over switch is in a high speed at the time of using a microphone by providing a switching means to interlock with the inserting and extracting action of the microphone to a microphone jack and give priority over a dubbing speed changing-over switch. CONSTITUTION:When a microphone is not inserted into a microphone jack 13, an earthed switch terminal (b) of the mike jack 13 is always brought into contact with an electric power source terminal (a), a resistance 22 is earthed and therefore, a transistor 21 for switching comes to be the OFF condition. For such a reason, the speed of a motor 15 can be changed optionally by a dubbing speed changing-over switch 17 and a high speed dubbing can be executed. When the microphone is inserted into the microphone jack 13, the base of a transistor 21 for switching cannot be pulled into the earth, a base electric current flows through the resistance 22 to the transistor 21 for switching, the ON condition is obtained, and even when the dubbing speed changing-over switch 17 is changed over to a high speed side, a standard speed can be kept.

Abstract: PROBLEM TO BE SOLVED: To precisely measure the moving speeds of a plurality of moving bodies at the same time by emitting a light to an identification code set on a moving body, storing the light receiving time of a light receiving part in a data storing part, and calculating the moving speed from the stored light receiving time. SOLUTION: A light is emitted from a light emitting part 11 to an identification code arranged on a moving body, and received by a light receiving part 12. When the emission of light from the light emitting part 11 is continued, and two or more data having the same identification code are stored in a data storing part 14, an arithmetic part 16 calculates the moving speed of the moving body. The moving speed is calculated by dividing a preliminarily stored distance interval by the interval of light receiving time. Since the data storing part 14 is writable at high speed, and an identification code containing much information is usable therein, the number of identifiable moving bodies can be increased, and the using range is extended.  A number of identification codes can be recognized in a short time, and identification of adjacent moving bodies and calculation of the moving speeds can be surely executed.
