Title: Control power supply switchgear
Inventor: MAENO TAKAYOSHI
IPC: H01H33/59
Filed: 1994-05-13
Abstract: PURPOSE:To prevent generating transient output voltage at opening time by supplying positive/negative electrode voltage from a respective (a) contact terminal of a coil contact and zero voltage from a (b) contact terminal through a (c) contact to a load device. CONSTITUTION:In a two-pole power supply switch 1, when it is placed in a closed circuit condition, a transistor Tr24 is placed in an on-condition by voltage divided by a constant voltage diode 21 and fixed resistors 22, 23, in a voltage drop detecting part 2. Then a coil 31 of a relay 3 is excited, to place a side of an (a) contact terminal 32a in a closed condition, and positive/negative electrode voltage V3, V4 is supplied to a load device 5. Next when the switch 1 is opened, the positive/negative electrode 3, 4 is decreased to turn off the Tr24 in the detecting part 2. The relay 3 is turned off by releasing excitation, and (b) contacts 32b, 33b are placed in a closed condition to force the positive/ negative electrode voltage V3, V4 to be zero volt. Thus, transient output voltage V5 is not output from the load device 5.

Title: Ac driving circuit of polarized magnet
Inventor: YOKOYAMA YOUICHI
IPC: H01F7/18
Filed: 1982-07-15
Abstract: PURPOSE:To realize operation of polarized magnet with an AC by controlling a control electrode of a semiconductor switching element connected in series with a coil with a voltage sent from a circuit consisting of a diode, a capacitor and a resistor. CONSTITUTION:When an AC voltage is applied across terminals (a) and (c), a current flows through a diode D   capacitor C   resistor R2 since resistors R1, R2 are set as R1>>R2. Moreover, when a gate voltage of SCR exceeds the predetermined voltage, the SCR turns ON. Thereby, a current of positive half cycle flows into a coil L1 in the set side. Meanwhile, when voltage and current are inverted, a current does not flow into the coil L1 and a charging voltage of capacitor C is gradually discharged. When the power supply voltage becomes positive again, a capacitor C is charged again. When a voltage of capacitor C increases gradually, a gate voltage of SCR drops and the SCR turns OFF and thereby the coil L1 becomes non-conductive. For the set operation, a voltage must be applied to the terminals (b) and (c). In this case, the same operation as described above is also carried out.

IPC: H01L21/28
Filed: 1979-09-26
Abstract: PURPOSE:To prevent the breaking of an Al wire by etching PSG by using an Si3N4 mask. CONSTITUTION:A plasma photo etching is applied to an Si3N4 film 7 by a resist mask 5. Then, PSG4 is etched by an Si3N4 mask 7. At this time, a flaw in the Si3N4 will occur. Next, a P diffusion layer 8 is formed and the Si3N4 at a flaw section is flagged by converting the Si3N4 into the PSG to smooth a shape at a connection section. A short circuit across an Al wire 6 and a substrate 1 will be prevented by the presence of the N type layer 8. The Al wire 6 is formed by removing a thin PSG film 9 generated at the times of P diffusion. The breaking of the Alwill not follow as the connection section is sufficiently smoothed by the P diffusion and the moisture from the outside is interrupted by an Si3N4 film 7 and phosphoric acid and corrosion will not present.

Title: Reformer of hydrocarbon fuel
Inventor: TABATA KENJI
IPC: C01B3/38
Filed: 1982-07-15
Abstract: PURPOSE:To improve the efficiency of reforming of hydrocarbon into inorg. gas in the titled apparatus by attaching heaters for heating a gaseous mixture contg. hydrocarbon and a reforming catalyst body to a cover for exchanging the catalyst body placed opposite to the catalyst body so as to heat almost uniformly the gaseous mixture and the catalyst body. CONSTITUTION:Heaters 12 are heated to a prescribed temp. such as 800-850 deg.C, and a gaseous mixture of hydrocarbon with air is fed 4 to a reformer 1 and slightly preheated by the remaining heat of the heaters 12 during passing through a path 5. The preheated gaseous mixture is further preheated during passing through a gap 20 and the space around the heaters 12 fixed with angle iron 13. Once the preheated gaseous mixture reaches a reforming catalyst body 6 preheated with the heaters 12, it initiates reforming reactions including the partial oxidation of the hydrocarbon with the air. Since the oxidation is an exothermic reaction, the mixture is required to be heated to the reaction temp. only at the beginning by supplying an electric current to the heaters 12. The gaseous mixture is reformed into inorg. gas contg. H2 and CO2 as principal components, and the resulting gas is passed through an outlet 8, stored once in a gas holder, and used.

Abstract: PURPOSE:To prevent the mechanical damage at the fitting part from occurring by a structure wherein the highly accurate positioning of a movable platen and a stationary platen becomes possible by supporting the movable plate freely shiftably radially with the sliding surfaces of reinforcing members. CONSTITUTION:Reinforcing members 18 are provided between a mold-clamping flange 12 and a stationary platen facing to the flange 12, both of which are connected with tie rods 16 and clamping nuts 20 enabling to act the force in the direction to bring them close to each other. A movable platen 26 is axially guided freely slidably by means of the sliding surfaces 28a of the reinforcing member 18. The extension line of the sliding surface 28a of the reinforcing member 18 in the cross-section normal to the axis is made so as to intersect the center of the movable platen 26. Consequently, the reinforcing members 18 prevent the mold clamping flange 12 and the stationary platen 14 from deforming. In addition, because the movable platen 26 is supported by the sliding surfaces 28a of the reinforcing member 18, the positional accuracy of the movable platen 26 is ensured regardless of the deformation of the movable platen 26 due to the change of temperature.

When the heterogeneity of the ion irradiation distribution by the ions (d) is detected, a wafer support base 17 is moved backward along a guide rail 19, and the focal position of ions irradiation is shifted backward. The ion monitor 16 is removed from an ion beam passage, and ion irradiation is applied to a wafer 18.

Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary gas supply so as to eliminate the consumption of the battery of a meter and that of a controller. SOLUTION: A controller 8 sends a gauge examination value request for requesting the gas consumption measured by a measuring part 11 as a gauge examination value to a gas meter 1.

A calculation part 35 converts the gauge examination value sent from the gas meter at gauge examination value request interval to a number of times and subtracts the converted number of times from the number of times read by the card read part.  A card write part 39 writes the remaining number of times obtained by the calculation part in the prepaid card. A control part 51 closes a shut off valve 13 in the gas meter when the remaining number of times of the prepaid card reaches a preliminarily determined number of times.
