Title: Electric discharge machining controller
Inventor: TAKAWASHI TAMIO
IPC: B23H1/02
Filed: 1985-06-03
Abstract: PURPOSE:To improve the follow-up property of servo control by controllably changing gain according to the output in every predetermined cycle of a register while supplying the gain to a spindle feed gain controller the output of which is supplied to a position servo system. CONSTITUTION:The servo signal of a judging circuit 18 permits an AND circuit to generate the AND output which is integrated for a predetermined time in an UP-DOWN counter 26. The values counted by the counter 26 in every predetermined time are held by a register 28 to be supplied to the input of a spindle feed gain controller 52. Thereafter similar operations are repeated to control the spindle feed gain from said controller 52 as a function of the difference between the output values of the register to reduce the spindle feed gain when the difference between the present output value and the right preceding one of the register 28 is larger than a set value. Also, when said difference is smaller than the set value, the servo signal for controlling said gain to a predetermined value is generated to a sample value control system. Thus, the servo control having satisfactory follow-up property can be provided.

Inventor: OGATA KIYOSHI
IPC: C23C14/22
Filed: 1992-05-13
Abstract: PURPOSE:To attain excellent adhesion of a film to a substrate. CONSTITUTION:Ions 12 are implanted into the film forming surface of a substrate 11 to form an ion implanted layer 13 on the film forming surface of the substrate 11. An underlayer 15 contg. a group IVA element is formed on the film forming surface of the substrate 11 by vapor deposition and irradiation with ions.

IPC: B41J11/26
Filed: 1990-05-10
Abstract: PURPOSE:To make a driving shaft independent of the rotation of a platen by a method wherein a carriage is moved to a specified position at the time of setting perforated paper to sprockets, and a cut-off member, interlocked with the movement of the platen, disconnects the connection between the platen and a driving shaft of a tractor that are engaged with a connecting member. CONSTITUTION:A carriage 40 moves leftward by a specified extent from a position (the position outlined with full lines in the attached figure) for the start of printing as an operator operates a disengagement switch, and thereby a part of the carriage 40 comes in contact with a pin 55 provided to a fork lever 57, making the fork lever 57 turn clockwise round a supporting shaft 54. By turning the fork lever 57 in the clockwise direction, a thrusting member 53 moves rightward to thrust a driving gear 29 in the right-ward direction. By the above-mentioned thrusting, the driving gear 29 slides toward the right, resisting a spring 32, and becomes disengaged (as illustrated with two-dot chain lines in the attached figure) from an idle gear 28. Therefore, the driving gear 29 and a driving shaft 22 become rotatable, being independent of other gears 28, 4, 5 and a center shaft 2 of a platen 1.

Abstract: PROBLEM TO BE SOLVED: To obtain an optimum trade-off between control and emission current, and provide a field emission element having an improved mutual conductance by positioning a gate edge in almost the central point between the tip of a cathode emitter and an anode. SOLUTION: In a side field emission element 10, an electron emitter electrode member 30 made of a thin film of tungsten or the like is laterally arranged to the upper surface 25 of a substrate 20 made of glass or the like.

IPC: H01L29/778
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device of excellent high-frequency characteristics which has small source parasitic resistance and small gate-drain capacitance. SOLUTION: A buffer layer 2 and a high electron mobility transistor(HEMT) active layer 3 are deposited on a semi-insulating GaAs substrate 1. After source and drain electrodes 4a, 4b are formed on an uppermost n+GaAs layer 3a of the HEMT active layer 3, a photoresist film 5 is formed which has a first aperture 5a in a gate electrode forming region and a second aperture 5b above the drain electrode. Recess etching is carried out using the photoresist film 5 as a mask, and a gate electrode 8 is formed on the resulting gate recess region 7. In the recess etching, the shape of the gate recess region 7 is made asymmetrical with that of the gate electrode 8 by utilizing electrochemical etching effect based on the potential difference between the drain electrode 4b and the n+GaAs layer 3a. Thus, the source parasitic resistance is lowered and the gate-drain capacitance is reduced.

Title: Talking apparatus of mr imaging apparatus
Inventor: IGARASHI MIKI
IPC: A61B5/055
Filed: 1987-05-19
Abstract: PURPOSE:To clearly transmit the sound of an examinee to the outside of an apparatus, by providing a bone conduction microphone for converting the sound of the examinee to a signal. CONSTITUTION:A magnet 1 and a bed 3 are arranged in a measuring room 15, and an inclined magnetic field electrode 5, a transmitter 6, a receiver 7, a processing apparatus 8 and a control part 10 are arranged in a machine chamber 26 and a display 9 is arranged to an operating room 16 and an operating expert 14 operates the display 9 in the operating room 16. In order to perform talking between the examinee 4 lying on his back in the static magnetic field space at an imaging position and the operating expert 14, a bone conduction microphone 17 is incorporated as a part of this apparatus. Since the bone conduction microphone 17 directly picks up the sound of the examinee 4 as the vibration of his head to transmit the same, the noise such as the beating sound generated from an inclined magnetic field coil 12 is not picked up and, therefore, only the sound of the examinee 4 can be clearly caught by the operating expert 14.

Filed: 1995-05-19
Abstract: PURPOSE: To detect the change of an image and to switch a camera based on this detection in the case of automatically switching a camera of a monitor system composed of plural video cameras. CONSTITUTION: A luminance signal is separated from the image sent from a camera switching part 4 by a luminance signal separating part 5 and converted to a digital signal by an A/D converting part (first luminance signal D1). This signal D1 is temporarily stored in a frame memory to be read out. This device is provided with 1st and 2nd frame memories 8 and 9 and 1st and 2nd switching circuits 7 and 9 in order to avoid the simultaneous processing of storage and read. The signal to be alternately read from these memories is defined as a second luminance signal D2 and based on these luminance signals D1 and D2, a video change amount detecting part 11 detects the amount of change between both the images. This detected change amount is compared with a prescribed threshold value 13 and the presence/absence of motion in the image is discriminated.  When there is no motion in the image, the camera is immediately switched to the next camera, and when there is any motion, video recording is performed while keeping a switching part 4 at that camera for a prescribed time.
