Abstract: PURPOSE:To reduce the dispersion of characteristics of low threshold value current as well as among manufactured semiconductor laser devices while easily controlling active layer positions by a method wherein high resistant current blocking layers formed not only on the surface of semiconductor substrate but also on the side of groove. CONSTITUTION:An SiO2 thin film 11 is deposited on the surface of a semiconductor substrate 2 and a stripe-type window 12 is formed in the direction of (110) by photolithography while a groove 5 with almost vertical sectional shape is formed by etching process. Next when the inclined semiconductor substrate 2 is implanted with impurity ion in the vertical direction, the surface of semiconductor substrate 2 and the left side of groove 5 only are coated with the impurity. Then the semiconductor substrate 2 is turned in the horizontal direction by the same angle in the direction reverse to (110) to implant with ion conforming to the same process. Through these procedures, an ion implanted layer 13 may be formed on the side of groove 5 in addition to another ion implanted layer 4.

Title: Heat transfer printer
Inventor: MAEKAWA TAKASHI
IPC: B41J2/36
Filed: 1984-04-20
Abstract: PURPOSE:To enable an high quality printing by varying voltage to be applied to a recording head between the incoming and outgoing operations to uniformize the density of printing to be made on a recording paper. CONSTITUTION:When a signal (a) indicates that a recording head 1 is in the outgoing operation, a selector 15 connects a resistance 12 to a power source and outputs a reference voltage VB as a specified value to a regulator 11. The regulator 11 outputs a drive voltage VD to the recording head regulating the input voltage VI to perform a printing operation according to the drive voltage VD. When the recording head 1 receives a signal indicating the incoming operation, the selector 15 connects resistances 13 and 14 to the power source to output a reference voltage VB' different from the reference voltage VB to the regulator 11. When the recording head 1 performs the incoming operation, the printing is easier to deteriorate than in the outgoing operation. The voltages VD and VD' are set by adjusting the variable resistance 14 to ensure the printing of the even density both in the outgoing and incoming operations.

Title: Etching of copper thin film
Inventor: ONO KAZUHIDE
IPC: H01L21/3213
Filed: 1989-03-30
Abstract: PURPOSE:To execute a directional etching operation of a copper thin film by a method wherein a substrate arranged on an electrode is heated, a reaction gas as a mixture of silicon tetrachloride and nitrogen is introduced into an etching apparatus and high- frequency electric power is applied between counter electrodes of the etching apparatus. CONSTITUTION:A mixed gas system 5 of silicon tetrachloride and nitrogen is used as a gas system; an electrode 1 on which a substrate 2 as an object to be etched is arranged is heated; the substrate 2 is heated to a prescribed temperature. Copper reacts with a chlorine radical formed when the silicon tetrachloride has been decomposed by an electric discharge and it is transformed into copper chloride, however, since the substrate 2 is heated to a high temperature, the copper chloride is easy to evaporate and an etching operation of a copper thin film progresses. The silicon tetrachloride and the nitrogen are decomposed by an electric discharge and a silicon nitride film is formed on the surface of the substrate 2; however, since ions which are perpendicularly incident on the substrate 2 remove the silicon nitride film on the surface of copper, the etching operation of the copper thin film progresses. However, since the ions do not hit sidewalls of a pattern which has been covered with a mask material, the sidewalls are covered with the silicon nitride film. Thereby, it is possible to execute a directional etching operation of the copper thin film.

Title: Double control system of sequence controller
Inventor: KITANO HIROSHI
IPC: G05B9/03
Filed: 1980-06-13
Abstract: PURPOSE:To improve reliability by incorporating a minor sequence controller (SQC) in the I/O module of an SQC, and by employing the doubled structure of the SQC and minor SQC to a part which requires safety specially. CONSTITUTION:The CPU25 of an SQC2, when a signal B which does not require double control is inputted to its input MD20, reads a control program, corresponding to the signal B, from a memory 26 and outputs a control signal C which does not require doubling, from its output MD21. When a signal A requiring the doubling is inputted, the CPU25 reads a corresponding program from the region 26a of the memory 26 and outputs a control signal D required for the doubling from the output MD21. On the other hand, the CPU32 of a minor SQC3 reads the same program as that in a memory area 26a corresponding to the signal A from a memory 33 and then outputs a signal E required for the doubling from an output circuit 31. Then, the signals D and E are ANDed at the outside of the SQC1 and only when the signals D and E coincide with each other, the output signal of the SQC1 is applied to a controlled system.

IPC: H01J31/12
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To fabricate an image forming device without deformation of internal composite parts, dispersion or the like and without heating it for spacer forming in a vacuum envelope or intimate-contact sealing of the vacuum envelope by forming a spacer of a plurality of materials including a fusion crystal polymeric resin and structurally forming a spacer bonding face of the liquid polymeric resin. SOLUTION: To support an atmospheric pressure in a vacuum container and hold a distance (d) between a rear plate 1 and a face plate 2, a spacer 12 of a crystal polymer resin is formed in the vacuum container. The distance (d) is increased to an extent free of the generation of electric discharge in the vacuum du to a high voltage. Since emission electrons of an electron emission element 5 have their finite widening, if the distance (d) is large, overlapping with the adjacent pixels is generated, color mixing and contrast reduction is generated, therefore, the distance (d) of several hundreds of μm to several tens of mm, that is space height is set with respect to a high voltage of several kV to several tens of kV.  Further, the reduction of the number of spacer assembling processes and simplification are achieved by providing a bonding layer in which a spacer 12 itself is structurally formed of the liquid crystal polymer resin.

Abstract: PURPOSE:To provide an alarm supervisory device in which an alarm buzzer is matched with the alarm display of a CRT for an alarm contact whose state is changed in a time shorter than the input and output cycle of a CRT display device, and responsibility to the alarm contact can be improved. CONSTITUTION:When an abnormality occurs at a plant, alarm contacts 3a-3c are operated, and alarm input signals D1-D3 are outputted.

Filed: 1991-04-12
Abstract: PURPOSE:To improve the quantity of dissolved ozone and oxygen. CONSTITUTION:Mixed gas of oxygen and ozone is mixed with feed water with a mixing pump 31 being in a pressurized state. The feed water is taken in from a feed water taking-in pipe 41. The mixed gas forms fine bubbles under pressure by the mixing pump 31 to be dissolved in the feed water. The mixed gas not dissolved floats remaining fine air bubbles. The mixed water delivered by the mixing pump 31 is introduced into a pressurized tank 33. While the fine bubbles of the mixed gas floating in the pressurized tank 33 stays under pressure, they are further dissolved in the mixed water. Thus ozone treated water in which much ozone and oxygen are dissolved is discharged from the pressurized tank 33 through a discharge pipe 65.
