Title: Device for heating and evaporating electron beam
Inventor: NAKAJIMA SHINOBU
IPC: C23C14/32
Filed: 1986-02-03
Abstract: PURPOSE:To eliminate the need for material replenishment during operation by the use of a large-capacity crucible and to prevent bumping by the melting away of the compd. film on a melting surface by providing a means for rotating the crucible and deflecting an electron beam and uniformly heating the electron beam. CONSTITUTION:A coil 31 is excited by an excitation power source 32 to generate magnetic lines of force between arms 30a and 30b and to exert the force toward the right side of the figure by Fleming's left-hand rule to the electron beam 11. The output voltage of the power source 3 is increased and decreased according to a pre scribed period to periodically fluctuate the magnitude of the force that the electron beam 11 receives so that the irradiation spot SP of the beam 11 on a material to be heated and evaporated (evaporating source) 4 is moved back and forth in a route lconnecting the rotating center part and peripheral edge of the melting surface of the evaporating source 4. On the other hand, the crucible 20 is rotated by a motor 22 and a gear box 21 to rotate the melting surface. The spot SP eventually moves over the entire surface of the melting surface, thereby uniformly heating the surface. The compd. film is immediately heated to melt and is thereby annihilated by the movement of the spot SP even if the compd. is generated.

Title: D/a conversion circuit for audio
Inventor: TOKUHISA SEIICHI
IPC: H03F1/32
Filed: 1992-01-13
Abstract: PURPOSE:To perform D/A conversion for audio with satisfactory sound quality by connecting an over second-order LPF composed of only a passive element to the output of a D/A converter and inputting an unwanted high frequency component, which is outputted from the D/A converter together with a voice signal, to an amplifier after attenuating the component. CONSTITUTION:The unwanted high frequency component contained in an analog signal output 1a of a D/A converter 1 is inputted to a non-inverted input 3a of the operational amplifier after being sufficiently attenuated by a fifth-order LPF 2 in advance. Thus, an output voltage 3c of the operational amplifier can sufficiently follow up the change of an input signal, and the output of the operational amplifier can be prevented from being distorted. Because of the over second-order LPF, flatness can be provided for both of a cut-off characteristic to a large high frequency component and a frequency characteristic in a voice band by suitably selecting the characteristic of the LPF. Thus, the unwanted high frequency component outputted together with the voice signal can be inputted to the amplifier after being attenuated.

Title: Constant-speed running control device for vehicle with supercharged engine
Inventor: MATSUOKA TOSHIHIRO
IPC: B60K31/00
Filed: 1989-01-31
Abstract: PURPOSE:To perform stable constant-speed running without changing the speed when the running load is high in constant-speed running control by preferentially increasing supercharging when the running load is high and the driving torque is lacking. CONSTITUTION:The opening of a throttle valve 7 is adjusted by PID control to attain the target throttle opening set based on a map in the stationary state (the state in which the actual car speed becomes nearly the preset car speed). Whether the actual throttle opening is large or not, i.e., whether a high-load operation state with the opening 80% or above is attained or not, is judged, if 'N0' is judged, whether a high-load operation is kept or not is again checked from the viewpoint of the intake negative pressure, if the high-load operation state is attained, the opening of a supercharged pressure adjusting valve 5 is adjusted to make the supercharged pressure maximum. The output of an engine 1 is increased by the supercharged pressure. The driving force required for acceleration is secured by increasing the supercharged pressure.

Title: Microcomputer
Inventor: INOUE HIROHIKO
IPC: G06F15/78
Filed: 1990-01-30
Abstract: PURPOSE:To reduce a load on software by providing an external interruption circuit which turns off an output signal compulsorily with an external interruption signal. CONSTITUTION:When the OFF state of the output signal is set compulsorily with a signal from the outside, a reset signal E outputs an H level in an ordinary state, therefore, a contact 1 goes to an L level when the external interruption signal F is set at the L level. Also, since the contact 1 is connected to the input of the NAND circuit of a latch circuit 1, a contact 2 goes to the H level, and furthermore, since the contact 2 is connected to the inverter circuit of a latch circuit 2, a contact 3 goes to the L level. Since the contact 3 is connected to the inverter circuit, the input of a tristate ICD goes to the H level, and goes to the OFF state. In such a way, it is possible to set the output signal on a signal line B at the OFF state compulsorily by setting the external interruption signal F at the L level, and to reduce the load on the software.

Inventor: MIYAGAWA KATSUHIKO
IPC: G05B9/02
Filed: 1984-02-10
Abstract: PURPOSE:To prevent misoperation by checking a plant operation process by a controller for nuclear power generation when an operator selects operation buttons corresponding to N divided steps of the process. CONSTITUTION:A push button is selected on a console panel 1 to output one of step command signals 20-22 and the controller 2 detects the input of the command signal, e.g. 20 and calculates corresponding lamp condition to generate a corresponding step decision signal 22 when the operator's selection is correct. Thus, the signal 20 and decision signal 23 are generated to generate a step permitting signal 26 and the controller 2 detects it and calculates a corresponding output value and control timing to generate a control output 15. This output 15 is sent to a low-priority controller when the permitting signal 26 is on and process control is carried out.

Title: Cutting method for ceramic green sheet and its device
Inventor: FUKUSHIMA HIROSHI
IPC: B28B11/16
Filed: 1990-01-31
Abstract: PURPOSE:To enable even the ceramic green sheet which has thin thickness and easily deforming property to be cut exactly and perfectly by a method in which the ceramic green sheet is cut in the state where it is kept on a carrier tape, and then it is separated from the carrier tape. CONSTITUTION:A green sheet is attracted on a cutting holder 17 in the state where it is kept on a carrier tape 1 and is fixed thereto, and then it is cut with a cutter 18. The tape 1 receives the blade pressure of the cutter 18 from its rear. Consequently, even when the green sheet 1 is thin and easily deformed, the part to which the blade of the cutter 18 is applied does not sink into the suction hole 17c on attracting surface, and the sheet may be perfectly cut along a prescribed cutting line. If the blade pressure of the cutter 18 is also set at the minimum strength capable of cutting the sheet 1, the tape 1 is not cut. Further since the blade pressure of the cutter 18 is received by the tape 1, the breakage of the blade or the bluntness of the tip do not occur easily, and the number of the replacement of the cutter is reduced.

Filed: 1987-02-02
Abstract: PURPOSE:To improve the quality of an engraved image peripheral part by finding the relative travel of a machining head corresponding to a time lag at a point of time of detecting the pattern edge and then, correcting the position of a detecting head or the machining head according to the travel. CONSTITUTION:A body 22 to be scanned is arranged on one XY table 18 and a material 28 to be machined is mounted on the other XY table 26. Before the engraving stage, an engraving device is operated to measure the travel (d) corresponding to the time lag from a point of time of detecting the pattern edge of a sensor till a point of time of starting and finishing to irradiate a laser beam. Next, when the engraving stage is started, only the XY table 18 is corrected by the travel (d) in the X direction before moving the table 18 and afterward, the XY tables 18 and 26 are driven synchronously. In this way, the time lag from a point of time of detecting the edge till the starting and finishing of the beam irradiation is dissolved and the indentation of the engraved image disappears and the quality of its periphery is improved.

IPC: H04N5/335
Filed: 1979-02-27
Abstract: PURPOSE:To enable to obtain the sensor output signal having stable characteristics, by obtaining the output signal unchanged on location, when the potential of transfer gate is low at the center and gradually higher toward the both ends and it is superimposed on the signal at the photo detection section. CONSTITUTION:The photo detection section 4 is constituted by arranging the photo transparent gate electrodes 3 of a plurality made of polycrystal silicon thin film one dimensionally via the photo transparent insulation film such as silicon oxide film on the surface of semiconductor substrate. The signal obtained from this photo detection section 4 is transferred 6 to the CCD shift section 5 provided in parallel with the photo detection section 4. Further, the potential of each transfer gate 6 is divided with the resistor 8 and the ground resistor 9 so that it is low at the center and sequentially higher toward the both ends. On the other hand, the stored charge of the photo detection section 4 is much at the center and less at the both ends, and when the signal of the gate 6 and the photo detection section 4 is superimposed, the output signal is almost uniform without change due to location. Thus, the sensor output signal having stable characteristics can be obtained.
