Title: Laser working device
Inventor: INOUE KIYOSHI
IPC: B23K26/064
Filed: 1983-05-18
Abstract: PURPOSE:To provide a titled device which increases working speed, cuts quickly a particularly thick body to be worked and improves the accuracy of a cut part by irradiating the body with two beams of laser light facing each other and changing the oscillating output according to the conditions of the part to be worked. CONSTITUTION:A body 7 to be worked is melted and cut by the focal part of the laser light emitted from laser oscillators 1, 2 and facing each other 2. Since the work is irradiated from both surfaces, the cutting speed is faster and the cutting is effective particularly for the thick body. It is possible to improve the accuracy of the surface by oscillating continuously the laser light for the straight cutting part and pulse-oscillating the laser light for the small curved or angled part. This method is applicable also to irradiation of a gaseous atmosphere or vertical irradiation with one oscillator.

Filed: 1983-05-16
Abstract: PURPOSE:To obtain a visible image having excellent observation image performance by forming of many photosensitive elements regularly arranged in two- dimensions and a fluorescent layer formed thereon, thereby reducing the radiation dosage emitted to an object to be sensed. CONSTITUTION:A radiation image detector is sequentially formed of a photosensitive elements 1, an insulating layer 2 and a fluorescent layer 3. The element 1 is, for example, formed of a photodiode 4 of a photoreceptor, and an MOSFET 5 of transfer unit. When radiation beam having strong and weak corresponding to the radiation transmission image of an object to be sensed is incident from below, the incident radiation is absorbed by the layer 3, and the fluorescent particles in the layer 3 emits a fluorescent light. Then, the fluorescent is photosensed by a photodiode 4 of the elements 1 of photodetecting members, and a signal charge is generated in the photodiode 4. In this manner, the intensity of the fluorescent light at the respective picture elements of the detector, i.e., the signal charge proportional to the intensity of the incident radiation is generated.

Title: Detector for length of running vehicle
Inventor: KIMOTO YASUO
IPC: G01B7/04
Filed: 1978-07-14
Abstract: PURPOSE: To detect accurately the length of a vehicle by calculating the length of the vehicle by determining the vehicle speed and its coil passing time via two search coils forming an alternating-current bridge circuit.  
     CONSTITUTION: Once search coils 3 and 3' forming the alternating-current bridge circuit detect vehicle 2, the bridge becomes unbalanced to generate a detection signal. Vehicle detection signals generated by coils 3 and 3' are processed by the Schmitt circuit and the counter counts up clocks passing through the gate which is open during the period from the generation of a Schmitt signal corresponding to coils 3' until that of a Schmitt signal corresponding to coil 3', so that the speed of the vehicle will be determined. With the gate closed during the vehicle detection period of coil 3, clocks passing through the gate are counted to determine the time vehicle 2 run between coild 3 and both determination values are multiplied each other to detect accurately the length of the vehicle by two search coils.
