Patent JP-S63226967-A (JP)
Title: Compound semiconductor junction type field-effect transistor and its manufacture
Inventor: NAKAMURA KAZUO
IPC: H01L29/80
Filed: 1987-03-16
Abstract: PURPOSE:To remove surface effects on a surface level or the like and to obtain a transistor without reduction in the amount of current and without occurrence of a short channel effect due to introduction of an (n) layer, by forming a gate region of opposite conductivity type and source and drain regions of one conductivity type in a semi-insulating layer formed on a thin channel layer of one conductivity type doped in a high concentration. CONSTITUTION:A thin channel layer 1 of one conductivity type doped in a high concentration is formed on a substrate 8 of a compound semiconductor, and a semi-insulating layer 2 is formed on the channel layer 1. A gate region 4, which is of conductivity type opposite to that of the channel layer 1, and source and drain regions 3, which are of the same conductivity type as that of the channel layer 1, are formed in the semi-insulating layer 2. For example, the n-type GaAs channel layer 1 is formed on a GaAs semi-insulating substrate 8, and the semi-insulating GaAs layer 2 is formed thereon, and the n<+> contact layer 3 and the p<+> gate layer 4 are formed in the semi- insulating layer 2. Thus, when the n-channel layer 1 and the semi-insulating layer 2 are continuously formed by a molecular beam epitaxial growth method or the like, an interfacial level between both layers can be removed.

Title: Automatic control device for gray level of ink
Inventor: KATO NAOKI
IPC: B41F31/02
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To deal with printing by calling the attention of persons, and solve the variation in gray level of ink through the automatic control of ink density, and thereby manufacturing an article having a highly qualified and steady value of goods by automatically detecting gray level, blurring, or color failure of ink in the print-finished sheet, and giving an alarm. SOLUTION: A printing sample sheet is detected by a color discrimination sensor for a printed sample sheet 10, and the detected value is digitized by means of an amplifier 2 to obtain a reference value, thereby setting a deviation for actuating an alarm 43 for notifying abnormality. The control device 5 of an ink viscosity automatic control apparatus 4, if it is not in interlinking mode with a color discrimination sensor 1, performs close operation. On the other hand, if it is in an interlinking mode, the control device 5 permits each automatic control value 6, 7 of water 8 and ink 9 to be operated in the direction of lessening the deviation of data irrespective of setting of viscosity by the ink viscosity automatic control apparatus 4. In this instance, it is preferable that he viscosity is controlled so that color of print-finished ink is maintained constant.

Title: Control system for reception buffer readout
Inventor: ITO TAKASHI
IPC: H03M7/40
Filed: 1987-03-17
Abstract: PURPOSE:To reduce a memory capacity and to simplify circuit constitution, by counting the number of frames in which data is written, performing readout when a counted value exceeds one, and stopping the readout when it is zero. CONSTITUTION:The counted value of a counter circuit 3 is supplied to a control circuit 4 by a signal (d). The control circuit 4, when a readout circuit 6 requesting the readout of a data string from a buffer memory 5 by a readout request pulse (e), outputs a readout permission pulse (f) when the counted value represented by the signal (d) exceeds 1, and makes the readout circuit 6 perform a readout operation. When the counted value represents zero, no readout permission pulse (f) is outputted, therefore, the readout operation of the readout circuit 6 is disabled. Thus, the readout of the data string from the buffer memory 5 is performed only when the data string>=one frame is held in the buffer memory 5 and a readable state is generated. In such a way, it is not required to prepare a surplus capacity at every buffer, thereby, it is possible to improve the activity ratio of the memory.

Title: Positioning controller
Inventor: HAMADA YOSUKE
IPC: G11B21/08
Filed: 1994-03-31
Abstract: PURPOSE:To reduce the error of followup to a target value by executing the correction of an acceleration feed forward table concerning a prescribed moving amount and outputting an acceleration feed forward signal inside the corrected acceleration feed forward table at the time of a moving/positioning operation after the correction. CONSTITUTION:An acceleration feed forward regulator 27 updates an acceleration feed forward table 21 by an operate signal 24 under moving for the prescribed moving amount. The operate signal 24 under moving for the prescribed moving amount is a signal adding an acceleration feed forward signal 22 and a positioning compensate signal 20, and the positioning compensate signal 20 is a signal for further reducing the followup error not completely following up a target position signal 16 but leaving by the acceleration feed forward signal 22. Thus, the signal adding the signals 22 and 20 becomes a signal improved rather than target value followup ability provided for the acceleration feed forward table before updating.

Title: Combustion equipment
Inventor: ISOZAKI TAKESHI
IPC: F23N5/24
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To provide combustion equipment which can be placed indoors and can detect the sudden generation of a negative pressure indoors. SOLUTION: When a negative pressure state, in which the air pressure of an airtight chamber declines due to the drive of a ventilating fan, is released by the shutdown of the ventilating fan, a current value of a frame rod, which is detected and outputted by an electrode 24 of the frame rod of a burning combustion equipment, declines. Also, if an open door is slammed to seal the inside of the chamber, the indoor air pressure suddenly drops to become the negative pressure state, and the current value of the frame rod suddenly decreases. When the current value of the frame rod suddenly decreases by more than the set current quantity within the set time, a detecting part 43 of the sudden generation of negative pressure detects that the negative pressure is suddenly generated.  When the current value of the frame rod gently decreases by the approximately set current quantity within the set time which exceeds the said set time, a detecting part 42 of the relaxation and release of the negative pressure detects and discriminates the relaxation from the release of the negative pressure.

Abstract: PURPOSE:To produce a high-strength ideal gear that makes less noise, by kneading reinforcing short fibers and a thermosetting resin, extruding the mixture from a nozzle to fill a mold with the resulting orientated material, and molding the material under heating and pressure. CONSTITUTION:Reinforcing short fibers and a thermosetting resin are kneaded and are extruded from a nozzle of an extruder to fill a mold with the resulting orientated material followed by molding under heating and pressure thereby producing a gear comprising a teeth section 1 of the fibre-reinforced resin and a steel boss section 2. In this case, the molding material wherein reinforcing short fibers are arranged approximately in one dimensional manner is charged circumferentially of a female mold of molds for a gear, and after the heating and molding, the reinforcing fibers will be arranged ideally along the teeth of the gear. Thus a high-strength ideal fibre-reinforced resin gear that makes less noise can be produced. The gear is particularly suitable to be used in automobiles.
