Title: Interface detector for pulse column
Inventor: ITO YOSHIBUMI
IPC: G01N29/28
Filed: 1987-01-20
Abstract: PURPOSE:To accurately detect interface by providing a linear array type transmitter receiver on an external wall nearby the interface between a light and a heavy liquid phases and scanning respective arrays and detecting a point where a reflected wave between the wall and liquid phases varies in signal level discontinuously as an interface position. CONSTITUTION:The linear array type transmitter receiver 14 equipped with many arrays is provided nearby the interface 11 between the light liquid phase and heavy liquid phase and the respective arrays are switched with the scanning signal 18A of a scanning signal control circuit 18. Further, the scanning reference signal of the circuit 18 is inputted to a counter 19 and an echo when the respective arrays are scanned is sent out to a CPU 22 through an input/output port 21. Then a difference in the attenuation of an ultrasonic wave sent by the transmitter receiver 14 with the difference in acoustic impedance among the wall, light liquid phase, and heavy liquid phase is utilized to count the number of arrays in small in echo height by a counter 19, thereby sending the analog output of the counted value. Consequently, the interface is accurately detected.

Title: Manufacture of semiconductor device
Inventor: KURODA HIDEAKI
IPC: H01L21/3205
Filed: 1989-01-19
Abstract: PURPOSE:To avoid the deterioration of an interlayer breakdown strength caused by a defect in a wiring pattern by a method wherein the defective part of the wiring pattern is exposed when a second insulating film is subjected to anisotropic etching and removed when a stopper layer is etched and, further, the removed part is covered with a third insulating film when the third insulating film is formed. CONSTITUTION:A silicon oxide film 8 which is a second insulating film is so formed as to cover a thin polycrystalline silicon layer 7 which is to be a stopper layer. Then the silicon oxide film 8 is subjected to anisotropic etching. If there is a defective part in a wiring pattern, the defective part 9 is exposed from the silicon oxide film 8 which is to be left on the side wall by the anisotropic etching of the silicon oxide film. Then the thin polycrystalline silicon layer 7 which is a stopper layer is removed by etching by using the remaining silicon oxide film 8 as a mask. At that time, a recess 10 is formed in a region where the defective port 9 exists. If a silicon oxide film 11 is again formed over the whole surface as a third insulating film, the recess 10 is filled with the silicon oxide film 11. As a result, the deterioration of an interlayer breakdown strength can be avoided.

Title: Manufacture of superconductive coil for charged particle deflection
Inventor: SHIBUTA NOBUHIRO
IPC: H01J37/141
Filed: 1986-01-20
Abstract: PURPOSE:To secure sufficient precision in size and shape, by pressing conductors for succeeding winding by a heating roller at an inner frame side to wind them and fusing one by one turn so that the neighboring conductors are gradually unified through a resin layer. CONSTITUTION:A conductor 10 is equipped with resinous layers 12 which are formed by coating and extrusion-covering the periphery of the flat-type superconductive conductor 11 with thermoplastic epoxy resin or with a thermoplastic resinous tape being wound. A succeedingly-wound conductor 10 is wound every turn on the precedingly-wound conductor while heating and pressurizing processes are performed by a heating roller 15 integrating a heater 14, to make the resinous layer 12 on the surface be once molten and adhere to the resinous layer of the precedingly-wound conductor. Thus, the molten resinous layers are solidified after the heating roller 15 has past. Neighboring conductors are integrated through the adhering resinous layer, and therefore the conductors exactly lie along the periphery of the curvature-equipped coil, securing high precision in shape.

Title: Pot for electromagnetic cooker
Inventor: KATAOKA AKIRA
IPC: H05B6/12
Filed: 1991-01-31
Abstract: PURPOSE:To see that the pot can be put directly on a table or the like immediately after heating by fixing a pad consisting of nonmetal to the bottom of the pot capable of being heated by electromagnetic induction. CONSTITUTION:The pot 1 consists of an iron material capable of being heated by electromagnetic induction, and to the bottom is fixed a ring-shaped pot stand 2 consisting of heat-resistant resin or the like. In heating, the pot itself is induction-heated by an electromagnetic cooker, but the stand at the bottoms is constituted of material not being induction-heated, so as compared with the bottom of the pot 1, the bottom temperature of the pot stand 2 is lower. Hereby, even if the pot 1 is placed directly on the table or the like, the temperature of the pot stand 2 hardly rises, so it can be placed at any place without an extra pot stand.

Title: Chrominance signal processing circuit
Inventor: IKEDA MAKI
IPC: H04N9/87
Filed: 1989-01-20
Abstract: PURPOSE:To reproduce a stable sub screen by controlling the burst level of a carrier chrominance signal for a main screen and the burst level of a carrier chrominance signal for the sub screen so that both levels can be equal. CONSTITUTION:A level comparator 19 compares the burst level of a first carrier chrominance signal 14 as the carrier chrominance signal for the main screen with the burst level of a second carrier chrominance signal 15 as the carrier chrominance signal for the sub screen and controls the gain of a second ACC circuit 17 so that both levels can be equal. Namely, while a changeover switch 24 outputs the output of the circuit 17 to an adder 12 when the burst level of the signal 14 is higher than a certain level, the switch 24 switches the output of a burst charger 16 and outputs the output to the adder 12 when the burst level of the signal 14 is lower than the certain level. Thus, even when the video input level of the main screen fluctuates, since the carrier chrominance signal for the sub screen also follows up the fluctuation, the stable sub screen can be reproduced.
