Title: Forming of integrated condenser
Inventor: NIIZAKI SHINYA
IPC: H01L27/04
Filed: 1979-11-22
Abstract: PURPOSE:To obtain an integrated circuit capacity of high precision through capacity adjustment by trimming a resistance which forms a composite integrated circuit or a monolithic integrated circuit. CONSTITUTION:Resistance R1-R4 and a capacity C0 are arranged in series, shortcircuting one ends of operating amplifiers OP1, OP2 and connecting with the contact points of resistances R2 and R3. The plus terminal of OP2 is connected to the input terminal of R1 and R2 and the plus terminal of OP1 to the contact points of R4 and R5. The output of OP1 is connected to the terminals of R1 and R2 and the output of OP2 to the contact point of R3 and R4. At that time, the input impedance is represented by the formula Zin=R1R3/jomegaC0.R2R4. If this circuit is realized in the form of a thin film composite circuit, R1-R4 can easily be laser-wrought for trimming so taht the resistance value can be adjusted. If R3 and R4 are trimmed, the capacity is changed by the function of the operating amplifier, so that even if R1 and R2 were adjusted, the equivalent capacity C and be changed. In this way, it is possible to absorb the unevenness of the basic capacity C0 and at the same time, increase the precision of the capacity value upto the level of a trimming precision.

Abstract: PROBLEM TO BE SOLVED: To enable the surge breakdown of inner elements to be avoided without increasing the chip area in an integrated circuit formed making use of an SOI wafer by forming a surge protecting circuit element on a thin film insulator layer to be a partly thin formed part of the film thickness of an insulator layer. SOLUTION: An inner element comprising an inner circuit as well as a surge protecting circuit element protecting the inner circuit directly connected to the input/output terminal of the inner circuit are formed by element separation on the second semiconductor layer 3 side of a semiconductor on the first semiconductor layer 1 through the intemediary of an insulator layer 2. In such a semiconductor layer 2, the insulator layer 2 is formed by partly thinning the film thickness so as to form a surge protecting circuit element on the thin film insulator layer 2a as a thin formed part of the insulator layer 2. For example, on the insular region 10 for surge protecting circuit element, an N type diffused layer 11 and a P type diffused layer 12 are partially formed on the surface of an N-type layer 3 so as to form the surge protecting circuit element.

Title: Turbine nozzle
Inventor: MUKAI EIJIROU
IPC: F01D9/02
Filed: 1984-07-23
Abstract: PURPOSE:To enhance the turbine step efficiency by providing an appropriate number of suction and blowout holes both in the downstream and overstream in a nozzle passage formed either in an inner or outer ring near the flank of a nozzle, by putting them in communication to each other through communication hole and thereby reducing the secondary flow loss. CONSTITUTION:In the side wall of an inner ring 2 of this nozzle 1, a suction 6 and a blowout 7 hole are bored radially along the neighborhood of the flank A of nozzle. The holes 6, 7 are put in mutual communication through a communication hole 8. At this time, the pressure in the holes 6, 7 correspond to the points 6h, 7h, respectively, shown on the pressure distribution diagrams on each nozzle vane on the flank A and back B. Part of the flow passing this nozzle 1 can be allowed to flow out from the suction hole 6 to blowout hole 7 by the use of pressure difference between the points 6h, 7h. The stream produced by this blowing-out is opposite to the flank swirl which gives a rise of secondary flow loss. Accordingly growth of the flank swirl is suppressed by this blowout stream, so as to reduce the secondary flow loss.

Abstract: PURPOSE:To reduce the size and cost of a device by arranging, in a passage for passing a pachinko ball, a thin film switch closed by the weight of the pachinko ball and a magnet for attracting the pachinko ball to reinforce the pressing force added from the pachinko ball to the thin film switch. CONSTITUTION:When a pachinko ball P passes a prescribed passage in a pachinko game machine, the protecting film 4 and upper film 5 of a thin film switch 3 are deflected by its weight and the attracting force of a magnet 2 buried in a base plate 1 forming a detecting element 18, so that electrodes 8, 9 on both upper and lower sides mutually make contact. On the other hand, when the pachinko ball P is passed through, the protecting film 4 and the upper film 5 are returned to the original positions by the respective elasticities, so that the electrodes 8, 9 are mutually separated. The contact and separation in the electrodes 8, 9 in both the upper and lower sides is detected by a detecting circuit, converted into electric signal, which is then transmitted to a control circuit and a counting circuit, respectively. Thus, the pachinko game machine is controlled to release a prescribed number of pachinko balls, and the passed pachinko balls are counted.
