Title: Electromagnetic wave driving type switch
Inventor: MATSUZAKI KAZUO
IPC: H01J17/40
Filed: 1993-07-28
Abstract: PURPOSE:To redouble electrons, and increase capacity in a carrying electric current by sealing lean gas in a space reaching a positive electrode to capture the electrons from a negative electrode through a passage vacuum space, and radiating a light wave intermittently. CONSTITUTION:Electrons (e) are emitted from a negative electrode 13 by field emission, and are accelerated in the direction of a positive electrode 15, and collide with atoms M of nitrogen gas, and deliver energy to the atoms M, and the atoms M transit to an excited condition. The excited atoms M exist in large numbers in a passage vacuum space 17 of the electrons (e), and when a light wave is radiated to these by driving of a semiconductor laser 18, the atoms M receive light energy (hnu). When the light energy (hnu) becomes dissociation energy or more, an ion pair is generated by ionization of the atoms, and the electrons are redoubled. Then, the electrons flow into the positive electrode 15, and ions rejoin with the electrons in the negative electrode 13, and are returned to lean atoms. When laser beam radiation is turned off, since an electric current flowing into the positive electrode 15 becomes zero, the radiation is turned on and off, so that a switch whose carrying electric current is large can be obtained.

Title: High luminance electron gun
Inventor: HAGIWARA HIROTOSHI
IPC: H01J3/02
Filed: 1980-12-27
Abstract: PURPOSE: To obtain an electron gun with a high luminance and long life by constituting the gun by use of a convex Wehnelt and a single crystalline LaB 6  cathode.  
     CONSTITUTION: Part of the electron discharging surface of a cathode chip 2 with a protruding end consists of <100> surface of a single crystalline LaB 6  cathode 4. A Wehnelt 6 having an internal cone angle not less than the vertical angle of the cathode chip 2, is placed between the cathode 4 and an anode. Owing to the above constitution, electrons discharged from <100> surface and appearing on a circular cone surface 4 of the cathode chip 2 form a crossover, which has a large current density and a small diameter. As a result, a luminance over 10 times that of a W hair-pin cathode can be obtained, and an electron gun of high stability can be obtained.

Abstract: PURPOSE:To detect the occurrence of the disconnection of a lead wire reaching to a thermistor and the missing of a connector, etc., by detecting a resultant resistance value of the thermistor and a resistor which is connected with the thermistor in parallel and deciding the temperature of a fixing device and the disconnection of a circuit. CONSTITUTION:The resultant resistance value of the thermistor 16 and the resistor 20 is detected so as to decide the temperature of the fixing device and the disconnection of the circuit. The resistor 20 which is connected with the thermistor 16 in parallel is capable of detecting the occurrence of the missing of the connector 1 and the disconnection of the lead wire reaching to the thermistor 16, to put it concretely, the disconnection of the lead wire between the junction A with a DC power supply and the junction B for an IC 2. That means, by applying the value applicable to the temperature and resistance value characteristic of the thermistor 16 as the resistance value of the resistor 20, the voltage at the normal time can be made largely different from the voltage at the disconnection time. Thus, the temperature of the fixing device and the disconnection of the circuit are decided while retaining the modification of the constitution of a hardware and the increase of the cost to a minimum.

Title: Production apparatus for semiconductor
Inventor: ODA MASAO
IPC: H01L21/205
Filed: 1986-08-06
Abstract: PURPOSE:To shorten a space between a substrate and a light source, and to increase optical illuminance by keeping the inside of a light source chamber under decompression in response to the degree of vacuum in a reaction chamber while using a substrate anchor block as a ground electrode and arranging a counter electrode sufficiently transmitting beams on the inside of the reaction chamber of a beam entrance window. CONSTITUTION:The inside of a device is evacuated, a discharge stop valve 18b is closed and the inside of the device is maintained under the state of decompression, thus simply removing pressure difference between a reaction chamber 1 and a light source chamber 2 on film formation extremely easily. Consequently, the plate thickness of a beam entrance window 7 can be thinned, and a light source 6 can be brought near to the substrate 5 side without lowering light transmittance by the increase of plate thickness. Accordingly, a thin-film can be shaped under the state in which optical illuminance on the substrate 5 is elevated sufficiently, thus remarkably improving the efficiency of formation of the thin-film. When a reaction product adheres on the light source chamber 2 side of the beam entrance window 7 and light transmittance lowers on film formation, the arrangement of a counter-electrode 14 and a substrate anchor block 3 as a ground electrode and etching by plasma discharge utilizing evacuation action on the inside of the light source chamber 2 are used, thus eliminating the lowering of light transmittance.
