Title: Controlling device for chopper used on electric rolling stock
Inventor: AWANO TOSHIAKI
IPC: B60L7/22
Filed: 1981-05-13
Abstract: PURPOSE:To obtain the stabilized braking control performance for the subject controlling device by a method wherein an overvoltage suppressing device consisting of a series circuit having a resistor and a thyristor is connected in series to a plurality of filter capacitors, and at the same time, the turn-on of thyristor is selected in proportion to the regenerative current and the regenerative voltage. CONSTITUTION:The overvoltage suppressing device, consisting of series circuit of overvoltage suppressing resistors 8a-8n and overvoltage suppressing thyristors 7a-7n, is connected to a filter capacitor 6b in parallel. Then, when the overhead voltage exceeds the prescribed voltage due to the reduction in regenerative load, the thyristor to be used to suppress overvoltage is turned on, and in this instance, each overvoltage suppressing thyristor is to be selected so that the same current as one which blows at the time when the generative current and the overvoltage are detected will blow. Through these procedures, as there is no change in the circuit current of the main motor, stabilized braking force can be obtained, and at the same time, no wasteful current flows in from the overhead line.

Title: Fence for correcting magnetic field of electron gun
Inventor: CHIYAARUZU DABURIYUU HANKUSU
IPC: H01J37/153
Filed: 1990-03-26
Abstract: PURPOSE: To provide a fence for correcting adjacent electron gun magnetic fields without the need to separate electron gun assemblies from each other by placing between the side walls of two parallel electron gun assemblies thin magnetic wafers which are magnetized so as to have opposite magnetic polarities on side surfaces. CONSTITUTION: Adjacent electron gun assemblies 10, 12 are normally spaced apart by about 1/4 inch, and waferlike magnets 22, 24 each of which is about 1/8 inch thick are arranged between and parallel to the electron gun assemblies 10, 12. Since the magnets 22, 24 are polarized in the cross direction of the wafers, one surface has the N pole at the front and the other surface has the S pole. Since the surfaces oppositely polarized are arranged inside a gap, their polarities repel those of the adjacent electron gun assemblies 10, 12. Thereby magnetic field interaction between the adjacent electron gun assemblies is inhibited, and the magnets of the electron gun assemblies correctly focus an electron beam toward a crucible 16.

Abstract: PURPOSE:To make it possible to carryout optimum heating cooking, by detecting a change in the shape of a heated article under heating cooking and controlling a heating status of a heater from the detection result. CONSTITUTION:A detection means A direct a detection light to a light receiving member 12 placed on the opposite side from each illuminant 11. While every detection light arrives at the light receiving member without any interference, an ON/OFF plate 20 which comprises a heating control means B opens all small ports 6 on the wall surface of a heating chamber 2, thereby circulating hot air. When bread P in a bread range 4 is expanded and projects from the upper part of the bread range 4, a part of detection light is cut off, and its change is detected by a detection circuit 14 on the light receiving side, which transmits the detected data to a control circuit S. The control circuit S compares the detected data with a stored cooking program; carries out arithmetic operation, and transmits the result to a drive circuit 18. A control rive motor 17 rotates a pinion gear 16 as often as required; lowers a rack 15 and the ON/OFF plate 20 and thereby closes the small holes 6 on several stages in the upper part. Therefore, heating is concentrated to the bread range 4 and ends cooking.

Title: Float for reflecting radar wave and its production
Inventor: MINETOMA MORIO
IPC: A01K75/04
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To eliminate disadvantages of a conventional expanded float for reflecting radar waves and prevent reflecting functions of the radar waves from simply deteriorating. SOLUTION: This float 10 for reflecting radar waves is produced by casting a low expandable synthetic resin to be an outer layer 3 into a metal mold, placing a synthetic resin sheet 1 containing powder of aluminum in a prescribed position on the outer layer surface, then filling a highly expandable synthetic resin, providing a nuclear part 2, heating the metal mold, forming a prototype of the float 10, inflating the resultant prototype by secondary heating and affording the final float 10 of a desired size. Since the sheet 1 which is a reflecting plate for the radar waves is fused, integrated and embedded in the interior of the expanded resin layer, no gap is present in the float 10, which is scarcely cracked. Since the sheet 1 is located in the float 10, the powder of the aluminum in the sheet 1 scarcely undergoes a chemical change such as oxidation.  Furthermore, the float body is not directly subjected to a force received from a net hauler at the time of installation and recovery of the float 10. Thereby, there is no fear of mechanically damaging the sheet 1.
