Title: Preparation of semiconductor device
Inventor: KAWASAKI KYOHIRO
IPC: H01L21/228
Filed: 1980-09-19
Abstract: PURPOSE:To facilitate the formation of a diffused layer having a small junction depth by a method wherein an insulated layer and the second metallic layer are applied on a metallic film provided as a diffusion source in the opening part of an insulated layr on a substrate, the second metallic layer is made to be a heat source by giving an electromagnetic energy thereto, and thereby a diffused-alloy layer is formed through the intermediary of the insulated layer. CONSTITUTION:The first insulated film 2 is applied on the substrate 1 and an opening 3 is provided. Next, the metallic film 4 as the diffusion source, the second insulated film 5 and the second metallic film 6 of a high-melting-point and low-resistance metal, which turns to be the heat source, are applied thereon. And, when the substrate 1 is left in a high-frequency magnetic field, the second metallic film 6 absorbs energy and thereby turns to be the heat source, and the metallic film 4 conducts thermal reaction with the substrate 1 through the intermediary of the insulated film 5, thus forming the diffused-alloy layer 7. The depth of the diffused- alloy layer 7 becomes equal to the thickness of the metallic film 4. By this constitution, the diffused layer having a small and uniform junction depth can be formed locally in a short time.

Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To actualize high-input impedance and low common mode gain by adding the output of a 1st amplifier and the output of a 2nd amplifier to obtain a control signal for the 1st and 2nd amplifiers.

Title: Pulse heat power source
Inventor: TAKASAKI HIROYUKI
IPC: H05B3/00
Filed: 1995-05-30
Abstract: PURPOSE: To reduce the vibration of a heater chip and increase the control response speed. CONSTITUTION: Transistors 3a-3d turn on or off the DC voltage obtained by a rectifier circuit 1 and a capacitor 2 to convert it into the AC voltage. This AC voltage is fed to a heater chip 5 via a transformer 4. The temperature of the chip 5 is converted into a voltage by a thermocouple 6, and the voltage Vs corresponding to the set temperature is outputted from a switch 8. A PWM control circuit 9 controls the on/off-time of the transistors 3a-3d based on the voltage Vs and the output voltage Vf of an amplifier 7 so that the temperature of the chip 5 becomes the set temperature. Since the frequency of the current fed to the chip 5 can be increased, the vibration of the chip 5 can be suppressed, and the control response speed can be increased.

Abstract: PURPOSE:To prevent the copy material lifting together with the pin and the tip of copy material from loosening when the punch pin is removed by constructing a recording paper processor so that a punch pin enters into a punch guide almost to the tip portion thereof. CONSTITUTION:Punch pins 56a, 56b extending from the lower ends of rolling chips 55a, 55b are received by pin guides 52a, 52b integral with a holder 52, then the punch pins 56a, 56b are moved up and down through rotation of a motor M6 and inserted/removed into/from dies 55e, 55f integrated with a horizontal table 55c so as to punch a paper chip mounted on the horizontal table 55c which constitutes a portion of the holder 52. Since the punch pins 56a, 56b have their tips diving into the pin guides 52a, 52b at positions slightly lower than the uppermost position, punched paper chip can be removed reliably from the pins.

Title: Cooling system for reactor plant
Inventor: FUJII TADASHI
IPC: G21C13/00
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To cool a sector containment quickly and efficiently from outside during occurrence of accidents by forming an outside pool in contact with the reactor containment by water injection in a short time and cooling the containment from outside. SOLUTION: A pipe 31 branched from an injection pipe 21 sends a part of cooling water in the pipe 21 by opening the valve 32 into the gap between the reactor building 9 and the containment 5 outside a pressure suppression pool 4. A pipe 32 sends cooling water in a condensate storage tang to a spent fuel pool by opening a valve 35. A pipe 33 sends the overflow water of the fuel pool 10 via a gap surge tank 16 to a spray header 42 outside the containment 5 by opening a valve 36. At the time of accident occurrence, the water level in the suppression pool 4 rises due to water injection from the pipe 21 to a drywell 2 and like as previously and the temperature also rises because of latent heat of inflow steam.  However, the outside pool 30 is formed outside the suppression pool 4 in the gap between the building 9 and the containment 5 owing to the water injection from the pipe 31, and therefore, the temperature difference between the pools 4 and 30 becomes large and the containment 5 can be cooled by natural heat radiation from the heat conduction surface of the wall itself of the containment 5.

CONSTITUTION:City water is supplied to a dissolution tank 1 through a water-feed pipe 2 attached to the bottom of the tank 1, slaked lime is charged into the tank 1 through a hatch 12 of a lid 3 and the water containing slaked lime is stirred with a stirring blade 5 and discharged to a well through an overflow pipe 8 laterally attached to the top of the tank 1. A 1st on-off valve 9 is attached to the attaching base of the overflow pipe 8 which is branched with a water-injection pipe 11 having a 2nd on-off valve 10 and directing toward the 1st on-off valve 9. The distance (S) between the injection pipe 11 and the 1st on-off valve 9 is <=2 times the inner diameter (d) of the overflow pipe 8. When the deposition of scale in the overflow pipe 8 reaches a prescribed level, the 1st on-off valve 9 is closed, the 2nd on-off valve 10 is opened and a large amount of water is introduced through the injection pipe 11 into the overflow pipe 8. The injected water dashes against the 1st on-off valve to wash off the scale by the flow energy and vigorously rushes toward the well to wash off the scale on the inner wall of the pipe.

Title: Electronic cash register
Inventor: KANARI YASUHIDE
IPC: G07G1/12
Filed: 1988-05-30
Abstract: PURPOSE:To prevent that a large amount of money is illegally encoded by recording amount data at the preceding resetting time and other amount data at present resetting time on a card and accepting a cancellation up to the balance between the two recorded amount data. CONSTITUTION:When the card is inputted, a card reader writer 2 reads respective amount data recorded on the first area and the second area of the card. Further, when a canceling key 13 is operated, and canceling amount information is inputted following the key operation, the balance between the amount data of the first area and the amount data of the second data and the canceling amount are compared. When the balance is smaller than the canceling amount at this time, the canceling processing is made into an error, and it is prevented that the canceling amount is added to the amount on the card and recorded on the card. On the other hand, when the balance is equal to or larger than the canceling amount, the amount obtained by adding the canceling amount to the amount data already recorded on the second area of the card is recorded on the second area. Thus, when the canceling amount is equal to or larger than the settled amount, it is judged that the amount is to be illegally recorded on the card, and the canceling processing can be made into the error.
