IPC: F03B3/04
Filed: 1982-09-20
Abstract: PURPOSE:To secure a space in the valve of a water-turbine power generator by drawing out either of the leadouts from the cables and pipes in the axial direction along the inside surface of the inspecting shaft and thereby utilizing the internal margin of the shaft effectively. CONSTITUTION:Lead-outs of the main terminals 7 for cables 6 are arranged distributed in the axial direction along the interior surface of an inspecting shaft 2 in its upper part. Accordingly the main terminals 7 are drawn out from the side wall of the shaft 2, being grouped up and down, to cause reduction of the number of main terminals 7 in arrangement viewed on a plane, so that the area required for arrangement of the terminals can be spared to ensure that they will not protrude so much toward the axis of the inspecting shaft 2. As a result, a good space 9 is reserved for carrying in and out of any equipment and materials into the valve.

Title: Ribbon feeder
Inventor: HIROSAKI YUKIHIRO
IPC: B41J2/325
Filed: 1987-06-30
Abstract: PURPOSE:To prevent paper and an ink ribbon from making frictional contact with each other, by cutting off the energization of a paper-feeding stepping motor and reversely rotating an ink ribbon-feeding DC motor for a predetermined time at the time of stopping the paper and the ink ribbon used on a label printer. CONSTITUTION:When a controlling means 11 receives a paper-feeding signal, a driving circuit 9 drives a stepping motor 2 to rotate a platen 1, and simultaneously applies a voltage to transistors 13, 16 to energize the transistor 16 through the transistor 13 and a DC motor 8, whereby an ink ribbon take-up shaft 7 is rotated by the motor 8. When the controlling means 11 receives a stopping signal, the driving circuit 9 stops the motor 2, cuts off the supply of power to the transistors 13, 16, and applies a voltage to transistors 14, 15 for a period of time (t). The period of time (t) is a period during which an inertia acts when the energization of the DC motor 8 is stopped. Therefore, the DC motor 8 is rapidly stopped. Thus, a paper 3 and an ink ribbon 4 are prevented from making frictional contact with each other, and clear printing can be achieved.

Title: Two terminal bidirectional thyristor
Inventor: OKA RITSUO
IPC: H01L29/861
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To enhance surge resistance by setting the lifetime of the surface of emitter region directly under a corner part shorter than that directly under the emitter thereby preventing concentration of current to the vicinity of corner part of the emitter region. SOLUTION: A base region 2 is exposed on the opposite major surface sides of a semiconductor substrate 1, an emitter region 3 is exposed to the surface layer thereof and a main electrode 4 touches the base region 2 and the emitter region 3 commonly on the opposite major surface sides. In such a structure, surge resistance can be enhanced by controlling the lifetime. More specifically, the base region (or collector region) directly under the corner of the emitter region 3 and the lifetime in the vicinity thereof are reduced. Consequently, current amplification Factor of a transistor is decreased directly under the corner of the emitter region 3 and current flow is retarded in that region. Since a surge current 14 flows through a region other than the vicinity of corner of the emitter region 3, concentration of current can be relaxed.

IPC: H01L21/304
Filed: 1987-06-30
Abstract: PURPOSE:To eliminate the crack of a wafer, and to automatically strip the wafer by providing a heater for heating the wafer, a vacuum chamber for containing at least a wafer section, and a wafer retainer for receiving it when the wafer is stripped from a substrate. CONSTITUTION:A glass plate 2 bonded with a wafer 3 is held by a retainer 6 at the hot plate of an electric heater 1. Then, the power source of the heater 1 is turned ON to heat it to a wax melting temperature or higher. Wax 5 is completely melted at this time, but it is experimentally confirmed that the wafer 3 is not dropped only with this. In this step, air bubbles 5a necessary to strip the wafer thereafter are introduced into the wax 5. Then, when a vacuum chamber 8 is evacuated in vacuum while the heater 1 is being heated, bubbles 5a in the wax 5 are expanded to generate a force for pressing down the wafer 3, the wafer 3 is finally dropped to a wafer receiver 7 mounted thereunder to complete the stripping of the wafer. In this method of stripping wafer, uniform force is applied to the whole surface of the wafer 3 to be reasonably stripped. Thus, the crack of the wafer can be eliminated.

IPC: B21B5/00
Filed: 1984-08-06
Abstract: PURPOSE:To provide a device which improves the fatigue life of an endless metallic belt to be run by being put on tension rollers by providing large- and small-diameter rolling rollers which face each other and press respectively said belt from the inside and outside circumferential sides thereof. CONSTITUTION:At least one of the tension rollers 10 and 11 is rotationally driven by a driving mechanism and runs endlessly the endless metallic belt 2 put thereon. The rollers 10, 11 are variable in the distance between the same and can apply tension to the belt 2. The 1st rolling roller 12 is provided between the rollers 10 and 11. This roller contacts with the inside circumferential surface of the belt 2 and presses the belt outward from the inside circumferential side thereof. The 2nd rolling roller 13 is disposed on the outside circumferential side of the belt 2 so as to face the roller 12. This roller has the outside diameter smaller than the outside diameter of the roller 12 and rolls the belt 2 between said roller and the roller 12. The belt 2 is then spread larger on the outside circumferential side than on the inside circumferential side so that the residual compressive and tensile stresses are generated respectively on the inside and outside circumferential sides. The durability of the belt 2 is thus improved.
