Title: Impregnated type cathode
Inventor: TAGUCHI TADANORI
IPC: H01J1/28
Filed: 1989-06-09
Abstract: PURPOSE:To lower the electron emission work function of the surface of an impregnated type cathode by providing a tangsten thin film, an oxide thin film containing tangsten and scandium, and an oxide thin film containing balium as multilayers on the surface of the impregnated type cathode wherein the hole portion of a heat resisting porous material is impregnated with electron emitting material. CONSTITUTION:The figure shows an impregnated type cathode comprising a base impregnated type cathode pellet 3, a barrier layer 4, a sleeve 5, a heater 6, and a multilayer film 10 consisting of an oxide thin film 7 containing Ba, an oxide thin film 8 containing W and Sc, and a W thin film 9. Then, the cathode is heated by transmitting electricity to the heater 6, whereby Ba and Sc diffused on the cathode surface are combined with oxygen formed by thermal decomposition of BaO, to form a complex compound layer (Ba, Sc, O) of extremely small thickness approximating that of a single or several molecule layers. Thus, by forming the (Ba, Sc, O) complex compound layer on the multilayer film 10, the electron emission work function of the cathode is dropped to as low as 1.2eV so that the electron emission ability of the cathode is largely enhanced.

Abstract: PURPOSE:To record the same sender name having plural print modes with simple operation by selecting picture information of the same sender name from any of plural memories and adding it to original picture information. CONSTITUTION:Supposing that raster regions of the first several tens of lines are regions for sender names, an operating section 11 connects a contact 3 of a changeover switch 3 to the position of a raster image generating section 5 in the first several tens of lines areas, and picture information data of the same sender name is inputted sequentially to a transmission processing section 6 from a memory 8 or 9 via a changeover switch 10.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To make applicable a spacer material with a uniform film thickness. SOLUTION: When columnar spacers are to be formed on the surface of a glass substrate 1, the spacer material 12 is fed at a constant rate of the quantity to a coating head 23 by a feeding part 22 and the spacer material 12 is applied on the glass substrate 1 by the coating head 23. In this process, the gap K between the lower end of the coating head 23 and the surface of the glass substrate 1 can be always kept constant by detecting the gap K between the lower end of the coating head 23 and the surface of the glass substrate 1 by a sensor part 24 and moving the coating head 23 in the perpendicular direction relative to the surface of the glass substrate 1 according to the detected data.  Since the spacer material 12 is applied on the glass substrate 1 while the coating head 23 kept in the aforementioned position is moved at a constant speed, any spacer material 12 without being restrictected to a limited number of columnar pacer materials can be applied to uniform thickness with good accuracy.

Title: Manufacture of gate turn off thyristor
Inventor: KIRIHATA FUMIAKI
IPC: H01L29/74
Filed: 1985-07-03
Abstract: PURPOSE:To improve the maximum controllable current by setting a segment of the side of low ON voltage near a segment which exhibits the lowest ON voltage of segments of an emitter layer to a disable state, thereby increasing the number of the segments of low ON voltage concentrated with current at turning OFF time. CONSTITUTION:A silicon wafer 1 has a p-type emitter layer 2, an n-type base layer 3, a p-type base layer 4, and an n-type emitter layer 5, and the layer 5 is formed as many insular projection segments surrounded by the layer 4. The segment having high ON voltage is quickly turned OFF as compared with the segment having low ON voltage at turning off time, and a current flows to the segment having low ON voltage. The number of the segments having low ON voltage controls the highest controllable current of a GTO thyristor. When the ON voltage is measured, the segment having lower ON voltage is not connected by a common cathode contacting electrode by cutting the cathode electrode 7 of the segment or coating with an insulating film, thereby disabling the operation. Thus, the number n1 of the segment having lower ON voltage is relatively increased as compared with the number n2 of the segment having higher ON voltage.

Filed: 1979-11-13
Abstract: PURPOSE:To eliminate the need for attachment such as emergency pump by transferring liquid between two storage tanks by siphoning after a transfer pipe is given a priming by pressurizing the inside of a tank of higher liqid level. CONSTITUTION:A liquid pump 6 of a destination tank 2 is operated to empty while a space 1a of a destination tank 1 is pressurized with a gas compressor 5 whereby a priming is performed to move liquid in the tank 1 to a transfer pipe 3. After the end of the priming for the liquid transfer pipe 3, the liquid in the tank 1 can be transferred into the tank 2 on the siphon theory only if the liquid flows from the tip of the transfer pipe 3. When both tank 1 and 2 become the same in the liquid level, the liquid in the tank 2 is transferred to another tank. Thereafter the liquid is allowed to be transferred to the tank 2 from the tank 1 by siphoning again. Thus the transfer of liquid can be done easily without any emergency pump.
