Title: Apparatus for producing billet having fine crystal structure
Inventor: MIZUKAMI HIDEAKI
IPC: B22D23/00
Filed: 1984-11-05
Abstract: PURPOSE:To produce easily a billet having fine crystal structure by providing a coil around a nozzle, supplying high-frequency current to the coil and turning on and off the supply of the current at prescribed time intervals. CONSTITUTION:An alternating magnetic field around the coil 7 is generated around the coil 7 when the high-frequency current is supplied from a high-frequency power source 8 to the coil 7. Eddy current is then passed through the molten metal 4 flowing in the nozzle 6 in the direction opposite from the direction of the current flowing in the coil 7. As a result, the electromagnetic force toward the axial center direction is acted to the molten metal 4 flowing in the nozzle 6 by the alternating magnetic field and the eddy current. The outflow of the molten metal 4 from the nozzle 4 is therefore thoroughly stopped by increasing the magnitude of the high-frequency current to be conducted to the coil 7. The molten metal drops 11 fall from the nozzle 6 into a casting mold 11 when the conduction of electricity to the coil 7 is turned on and off at the prescribed time intervals.

Title: Relay driving apparatus
Inventor: NAKAMICHI HITOSHI
IPC: H01H47/00
Filed: 1991-09-11
Abstract: PURPOSE:To lessen the degradation of the contact to improve the durability of the apparatus and control a large current with a small switching capacity, by consuming, with use of a Zener diode, the counter-electromotive force produced during opening operation of the relay contact, and thereby shortening the arc time period at the relay contact. CONSTITUTION:Depressing a switch 9 causes a signal to be inputted to an input terminal 1c of a control section 1 and causes in turn a power to be supplied to a display element 8 connected to an output terminal 1d. Simultaneously, a transistor (Tr)2 is turned on and the contact 4b of a relay 4 is closed, and, during only this period of time, arc discharge occurs, by which a load 10 is energized. Next, depressing the switch 9 again stops power supply to the display element 8 connected to the output terminal 1d, with the result that the Tr 2 is turned off. A counter-electromotive force is generated from a coil 4a of the relay 4 and this counter-electromotive force is consumed by a Zener diode 3. Accordingly, the relay 4 is opened in a very short time length after the Tr 2 is made off, so that the load 10 stops being energized.

Title: Method for measuring gap between heat transfer pipe and its supporting member
Inventor: WAKAYAMA SEIICHI
IPC: G01B17/00
Filed: 1987-09-18
Abstract: PURPOSE:To make it possible to ensure the measurement of a gap even if a heat transfer pipe has a thin wall, by a constitution wherein an ultrasonic wave probe that is inserted into the heat transfer pipe is positioned at a point that is offset from the central axis of the pipe, and an ultrasonic wave is inputted into the inner surface of the heat transfer pipe at an angle at which the ultrasonic wave that is orthogonal to the supporting surface of a supporting member in parallel with the central axis is transmitted. CONSTITUTION:An ultrasonic wave probe 4 is inserted into a heat transfer pipe 7 so that the probe is offset from the central axis of the pipe. When an ultrasonic wave 6 is transmitted from the probe 4, the sound wave 6 is obliquely inputted into the inner surface of the heat transfer pipe 7 owing to the offset position. A reflected wave 6a advances in the different direction from the probe 4. A part 6b of the ultrasonic wave 6 is refracted at the inner surface 7a, propagated through the material of the heat transfer pipe 7 and obliquely inputted into an outer surface 7b. The wave is propagated between the inner and outer surfaces 7a and 7b in a zigzag pattern. The wave is received with the probe 4 and selected. A part 6c of the reflected wave 6b is transmitted through the outer surface 7b, propagated so that the light crosses a supporting surface 8a of a supporting member 8 and undergoes regular reflection at the supporting surface 8a. The wave is propagated along the incident path in the reverse direction and received in the probe 4 as the reflected wave from the member 8.

Filed: 1994-09-28
Abstract: PURPOSE: To provide a discharge display device of a type having an electrode structure to hardly occur electric discharge concentration and to enable setting of adequate inter-electrode distances at which driving with a low voltage is possible regardless of pixel densities. CONSTITUTION: Discharge electrodes 36 are disposed in a laminar form in a part in the height direction of partition walls 22. On the other hand, these discharge electrodes 36 respectively have exposed end faces 32. Plural discharge projecting parts 34 are formed at equal intervals in the longitudinal direction of the wall surfaces 31 in such a manner that the distances between these end faces 31 are approximately equaled and, therefore, the discharge is executed exclusively between the end faces 32 when a prescribed discharge voltage is applied between the discharge electrodes 36 and 36.  Even more, the inter-electrode distances of the plural discharge projecting parts 34 facing each other are approximately the same and, therefore, the discharge is uniformly executed between all of the discharge projecting parts 34 and the approximately uniform discharge is effected within prescribed discharge spaces 26. In addition, the distance between a pair of the discharge projecting parts 34 and 34 is settable regardless of the intervals of the partition walls 22 and, therefore, the adequate inter- electrode distances at which the driving with a low voltage is possible are settable regardless of the pixel densities.

Inventor: HOSOMI SADASHIGE
IPC: H01L21/56
Filed: 1987-09-17
Abstract: PURPOSE:To prevent the dielectric breakdown strength between a lead frame and a metallic plate from reducing by a method wherein a frame supporting hole formed in such a way as to support part, of the lead frame by the supporting pins of a mold ing metal mold does not exist on the rear side of the lead frame, but exists on the surface side of the lead frame. CONSTITUTION:A molding resin 6 has a thin resin layer 6' for insulation and for heat conduction on the rear side of a chip mounting part and at the same time, is formed in such a way that the point part of a lead frame does not protrude to the exterior. Moreover, the lead frame is bent and formed in such a way that the position of the point part 2' becomes higher compared to that of the chip mounting part 2. Here, the ralation between the thickness T1 of the resin layer 6' on the rear side of the part 2 and the thickness T2 of the resin layer on the rear side of the part 2' is T2>T1. In case the rear side of a semiconductor device 10 is mounted to a metal lic plate for mounting, part of the surface side of the lead frame is exposed in a frame supporting hole 8, but all of the rear side of the lead frame is insulated with the resin. Accordingly, there is no possibility that the dielectric breakdown strength between the lead frame and the metallic plate is reduced due to a conductive foreign substance.
