Title: Semiconductor element
Inventor: SUGAWARA KAZUSHI
IPC: H01L29/78
Filed: 1985-07-01
Abstract: PURPOSE:To obtain the negative resistance characteristic at approximate room temperature by forming a semiconductor on a ferroelectric insulator layer which shows softening phenomenon of phonon at a temperature near room temperature and applying an electric field to said insulated layer. CONSTITUTION:On an insulator substrate 11 using glass, a ferroelectric insulator layer 12 is formed by gas-phase growth. For this ferroelectric insulator, LiTaO3 is used, a specified wave vector of which reduces to approximate zero in a predetermined critical temperature, namely which shows so-called softening of phonon. The critical temperature is reduced to about room temperature by doping impurities such as Fe in the insulator layer 12 at high concentration. On the insulator layer 2, an N-type semiconductor layer 13 is formed by doping a proper impurity in GaAs and subsequently, an emitter electrode 14-1, a collector electrode 14-2, a gate electrode 15 and lead wires 16 are arranged.

Title: Dc constant current source
Inventor: ISODA KENICHI
IPC: G05F1/56
Filed: 1987-06-12
Abstract: PURPOSE:To form a DC constant current source with less effect by the fluctuation of ambient temperature or internal heat by constituting the DC constant current source based on the critical current of a superconduction resistor. CONSTITUTION:The main circuit is formed by the DC power supply 1, a current control amplifier 3 and the superconduction resistor 4 kept in a constant temperature oven 5 at the critical temperature or below as a load. Then the input voltage of the current control amplifier is controlled to measure the voltage drop across both the terminals of the superconduction resistor while increasing the load current being the output gradually. When the load current is less than the critical current specific to the superconduction resistor 4, the superconduction state is kept and the voltage drop is zero. When the load current exceeds the critical current, the superconduction state is broken and the voltage drop rises suddenly to a positive value. The voltage across the superconduction resistor 4 is fed back negatively to decrease the load current being the output of the current amplifier 3 thereby forming the stable DC constant current source.

Title: Treatment by ozone reaction
Inventor: NISHIO KENICHI
IPC: B01J19/00
Filed: 1987-06-12
Abstract: PURPOSE:To shorten a treatment duration of an ashing operation or the like of a wafer or the like by specifying the duration which elapses until a gas containing ozone blown off from a gas nozzle comes into contact with the surface of a solid body to be treated. CONSTITUTION:A duration which elapses from the time when a gas containing ozone is blown off from a nozzle 2 to the time when it reaches the surface of a solid body 5 to be treated must be shorter than 5/10000th of a second. If the duration for this arrival is longer than 5/10000th of a second, the ozone which has been blown off from the nozzle 2 is decomposed before it reaches the surface of the solid body 5. For this reason, a distance between the nozzle 2 and the surface of the solid body 5 to be treated is set to be less than 1mm; the size of an opening of the nozzle 2 and the number of the nozzle are set in such a way that the linear speed of the flowing gas containing the ozone is faster than 2m/sec. By this setup, when a temperature of the silicon wafer 5 is higher than 250 deg.C, it is possible to remove a photoresist on the surface completely in an ashing duration of 60sec.

Title: Solar heat collecting device
Inventor: WATANABE TAKEJI
IPC: F24S90/00
Filed: 1981-09-14
Abstract: PURPOSE:A bypass pipe attached with a changeover valve is arranged parallel to a pressure reducing mechanism which forms a closed circuit with a heat collector for evaporating a flon type coolant. CONSTITUTION:A closed circuit is formed by a heat collector 10, a medium transfer machine 6, a condenser 7 and a pressure reducing mechanism 9 and the bypass pipe 12 attached with the changeover valve 11 is connected parallel to the pressure reducing mechanism 9. With the above structure, when the amount of insolation is large, the flon type gas phase coolant having its pressure loss compensated through the transfer machine 6 is converted into a liquid phase coolant by the condenser 7 and is transferred to the heat collector 10 through the changeover valve 11 so as to become vaporized while when the amount of insolation is small, the gas phase coolant which has been heated to a high temperature at high pressure through the transfer machine is converted into the liquid phase coolant, the pressure of the liquid phase coolant is reduced by the pressure reducing mechanism 9 and flows into the heat collector 10 at a low saturated temperature. As a consequence, the temperature of the coolant does not change during its passage through the heat collector and the difference between the real temperature and the surface temperature of the coolant becomes constant so that the amount of heat collection is increased and the heat collector 10 can be miniaturized.

IPC: H01J9/04
Filed: 1985-07-02
Abstract: PURPOSE:To reduce fluctuation of discharge starting voltage by impregnating with aqueous solution of electron emission material then heating the sintered member under vacuum to remove water and drying. CONSTITUTION:Tungsten-nickel sintered material is impregnated with aqueous solution containing 10% cesium carbonate then placed in vacuum chamber to perform evacuation and upon achieving vacuum of 10<-5>Torr, heating is started. Then heating is controlled to produce pressure lower than 10<-3>Torr with the maximum heating temperature of 150 deg.C. With this temperature, heating is continued to recover pre-heating vacuum condition or 10<-5>Torr pressure, to produce a sintered cathode. Consequently, fluctuation of discharge starting voltage is reduced while discharge starting voltage itself is lowered.

Filed: 1985-07-03
Abstract: PURPOSE:To prevent the floating of an automobile body from a hanger by providing a pin to the hanger carrying the body and inserting the pin into the hole perforated through the floor part of the body. CONSTITUTION:Plural holes 18 are perforated through the floor part 17 of an automobile body 1. A pin 23 corresponding to the hole 18 is provided on the pedestal 16 of a hanger 7. The body 1 is placed on the hanger 7 with the gear part 1a ahead in the traveling direction and conveyed to a processing soln. vessel 2. In this case, the pin 23 is inserted into the hole 18. The body 1 is immersed in a processing soln. 3 from the rear part 1a and the floating of the rear part 1a when carried into the vessel can be avoided, since a bag- shaped part is not presents at the rear part 1a. When buoyancy 33 is produced due to the structure of the body 1, the direction of the buoyancy 33 is different from the direction of the insertion and separation of the pin 23 into the hole and hence the rear part 1a of the body 1 is locked on the hanger 7 against the buoyancy 33. Consequently, the floating of the body 1 is surely prevented.
