Abstract: PROBLEM TO BE SOLVED: To attain easy design, high efficiency, and downsizing of a winding part by switching three-phase AC power supply and a power conversion part to a star connection when high the input voltage is high and a delta connection, when input voltage is low. SOLUTION: In the AC input of a single-phase full wave rectifier, when a U-phase line, a V-phase line, a W-phase line are connected to respective blocks of power conversion parts 17, 18, 19, the V-phase line of a three-phase AC power supply line is connected to a connecting point between the anode of a thyristor 20 and the cathode of a thyristor 21. The W-phase and U-phase lines of the three-phase AC power supply line are connected to the connection between the anodes of the thyristors 22, 24, and the cathodes of the thyristors 23, 24 respectively. At inputting of a three-phase 200 V, an on signal is inputted into the gates of the thyristors 20-25, and turns into a delta connection state. At inputting of a three-phase 400 V, the thyristors 20-25 are turned off, so that it turns into a star connection state.  It is thus possible to attain easy design, high efficiency, and downsizing of a winding part.

Title: Radiation sensitive organic high molecular material
Inventor: HATADA KOICHI
IPC: G03F7/039
Filed: 1986-04-28
Abstract: PURPOSE:To enable the fine processing with high pattern accuracy by a very small extent of irradiation by using a specified stereoregular polymethyl methacrylate as the principal component. CONSTITUTION:This radiation sensitive org. high molecular material contains polymethyl methacrylate having chemically bonded isotactic and syndiotactic components as the principal component. When the polymer is irradiated with high energy radiation such as electron beams, X-rays or ion beams, the stereocomplex structure of the irradiated part is destroyed and the solubility of the part in an org. solvent is remarkably improved, so that high molecular material can be used as a positive type resist material. The high molecular material has a much larger difference in solubility in an org. solvent between the irradiated and unirradiated parts than a general-purpose positive type resist. When the high molecular material is used, a resist pattern having high resolution can be formed by a small extent of irradiation.

Title: Semiconductor device and manufacture thereof
Inventor: KOSAKA YUJI
IPC: H01L29/788
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To suppress leakage of carriers from a floating gate to a control gate. SOLUTION: Each of memory elements 30 and 40 has a floating gate 14 of n type semiconductor formed on a semiconductor substrate 12 through a first insulating layer. A control gate 32 of p type semiconductor is formed on the floating gate 14 through a second insulating layer. Since the floating gate is made of the n type semiconductor and the control gate 32 is made of the p type semiconductor, a voltage applied to the second insulating film between the gates 14 and 32 is lower by a difference between work functions of the both gates, thereby enabling reduction of the quantity of carriers leaked from the floating gate 14 to the control gate 32.

If a base DC level of the TR14 is changed through the change in a DC level of a signal inputted to an input terminal 9, the DC level of the base of the TR3 is also changed via the resistors 18 and 19. As a result, no abnormal signal due to the change in bias is outputted to the output even with switching of the changeover switch 8. Further, the capacitor 20 is provided to separate signals at the terminals 1 and 9.

Filed: 1984-05-16
Abstract: PURPOSE:To miniaturize an ejection mechanism for pin gate runners without increasing a total cost by making the mechanism capable of moving first a die fixing plate and then a middle plate located between die fixing plates. CONSTITUTION:A gate is broken down by shifting a movable die plate 44 to the left for opening a die after molding. In addition, an ejector pin 46 gets into a cavity 40, ejecting and dropping a molding. Next, a hydraulic oil is fed into the right section of a chamber 20 for a liner ejection cylinder 14 and then the first slider 21 moves to the left, advancing a die fixing plate 24 away from a middle plate 26. After that, the second slider 22, pushed by the first slider 21 moves resulting in the separation of the middle plate 26 from a fixing die plate 12. Consequently, (pin gate) runners 42 located among a fixing die 48, the middle plate 26 and a spool bush 38 are ejected without fail.
