Title: Heater current control method for ion source of surface ionization type and device therefor
Inventor: HOSHINO HITOSHI
IPC: H01J27/26
Filed: 1991-02-08
Abstract: PURPOSE:To substantially extend the lifetime of an ionizer by automating a conventional manual operation system in interrupting the supply of heater current to an ion source of surface ionization type, quickly finishing the operation and leaving no deposit in the ionizer. CONSTITUTION:The variable voltage power supply 8 of a heater 7 is provided with a drive means comprising a motor 11 and a driver 12, and a processor 13. A voltmeter 9, a heater ammeter 10 and an ion current meter 6 are connected to the processor 13. Applied voltage is gradually lowered from heating state, thereby temporarily maintaining the heater 7 at a voltage or current level to hold an ionizer 3 slightly higher than ion generation critical temperature. Subsequently, after confirming that the ion current value of a Faraday cup 5 suddenly rises and then drops to a zero level, the voltage is again lowered to a zero level gradually.

Title: Composite ceramics and production thereof
Inventor: TAKAYAMA KOICHI
IPC: C04B35/04
Filed: 1990-02-19
Abstract: PURPOSE:To easily, efficiently obtain a Mg-ZrO2 composite ceramics by forming a mixture of magnesia and zirconia followed by calcination. CONSTITUTION:The objective composite ceramics can be obtained by mixing and forming of magnesia and zirconia followed by calcination at 1200-1600 deg.C for 1-3hr. Since ZrO2 is expensive, it is preferable that its content be lower in terms of cost; however, if the content is <10wt.%, the effect from ZrO2 incorporation will be insufficient; whereas if the content exceeds 30wt.%, granular growth will be developed due to sintering among ZrO2 granules, leading to residual expansion. And because of high heat capacity of ZrO2, much incorporation of ZrO2 will result in the higher heat capacity of the final composite material, thus being disadvantageous as a setter material. Therefore, the contents of ZrO2 and MgO are determined as 10-30wt.% and 70-90wt.%, respectively.

IPC: H01L21/22
Filed: 1989-02-20
Abstract: PURPOSE:To process in high quality without reducing semiconductors to be housed by disposing a gas room for injecting purge gas between the boat and lid of a reaction tube. CONSTITUTION:Between the lower end of a boat 8 inside a reaction tube 7 inserted a furnace 1 and a lid 20 at the lower end of the reaction tube 7, a gas room 12A made of quartz in the reversely U-shaped of an outer diameter slightly smaller than the inner diameter of the reaction tube 7 serving also as the supporter for the boat 8 is mounted air-tight on the lid 20. On the lid 20, holes 13A and 13B are disposed in the right and left in the center at a space of the inner diameter of the diagrammatic gas room 12A. To the hole 13B, the left end of a piping 17A is connected. The right end of the piping 17A is connected to a selector valve 11 disposed in an exhaust valve 16. An exhaust valve 17B is connected to the hole 13A. Therefore, since the temperature in the lower section of the reaction tube 7 can be raised when semiconductor wafers are heat-treated, a flat zone length can be increased. Thus, semiconductors can be processed in high quality without diminishing semiconductors to be placed on a boat.

A hot water temperature in a bathtub is detected by thermistors 5 while circulating hot water in the bathtub, and whether or not the hot water temperature in the bathtub is lower than a preset temperature - x deg.C, the preset temperature being set to a remote control device, is judged. In the case where the temperature thus judged is lower than the preset temperature - x deg.C, a burner is actuated for additional heating even without instructions of additional heating.

Title: Speed controller for motor
Inventor: NOGUCHI TOSHIHIKO
IPC: H02P29/00
Filed: 1988-02-24
Abstract: PURPOSE:To prevent the unexpected rotation of a motor when the power source of a speed controller is turned ON by adding a speed offset for setting the timing change of a torque command to zero to a speed detection signal. CONSTITUTION:When a control power source is turned ON, a switch 7 is changed to its '0' side to forcibly set an input to a speed controller 3 to '0'. In this case, since a motor is not rotated at this time point, a speed detection signal omegam is also '0'. Then, the output  omegam of a D/A converter 53 is set to '0', and the variation amount of a torque command T' during its period of time is stored. Then,  omegam is set to another value, and the variation amount of the T' is similarly stored. Then, the  omegam for equalizing the variation amount of the previous time to that of this time is searched. Then, the switch 7 is returned to a speed command value omegam' side. Thus, it can prevent the motor from rotating in an unexpected direction at an unexpected speed.
