Title: Hot plate
Inventor: TAKASHIMA YUKIO
IPC: H01L21/324
Filed: 1989-06-16
Abstract: PURPOSE:To prevent occurrences of dust resulting from the evaporized component of a resist by allowing the sectional form of a cover to be formed into the shape of a circular arc and further, the circular arc to have its recessed face downward. CONSTITUTION:A cover 1 is installed over a hot plate so that a circular arc like sectional form may hold its recessed face downward side and gas is injected from the top of the circular arc in the direction of both tangent lines inside of the circular arc and then, gas is discharged from both sides of the circular arc. Then, most of gas which is injected from the top of the circular arc in the direction of both tangent lines inside of the circular arc flows along the inside wall of the circular arc and is discharged from both ends of the circular arc. As a result, its gas acts as an effective fluid shield toward a circular arc like inside wall face and an evaporated component is unable to directly come into contact with the inside wall surface and then, no dust adheres to the inside wall surface. As the flow of gas, further, forms a circulating flow between its plate 4 and the circular arc, the evaporated component is discharged effectively. Occurrences of dust are thus lessened drastically.

Title: Printing device
Inventor: DAGURASU ENU KARII
IPC: H04N1/40
Filed: 1993-06-25
Abstract: PURPOSE: To eliminate the half-tone aliasing problem of a printer. CONSTITUTION: The edge segmentation circuit 16 of a printer having a high two-dimensional address possibility performs printing by using either a half-tone executing method or threshold method by controlling an image processor. The circuit 16 compares inclined values of (x) and (y) extrapolated from an extrapolation circuit with prefixed inclined values of (x) and (y) stored in the X- and Y-registers 22 and 24 of the circuit 16. Based on the comparison, the circuit 16 inputs 1-bit edge segmentation information to an edge segmentation mode switch. Depending upon the binary value of the edge segmentation information, whether '0' or '1', the edge segmentation mode switch is switched to a half- toner or thresholder and printing is performed by using either the half-tone method or threshold method by controlling the image processor.

Title: Fet multiplier
Inventor: SAKA HIROSHI
IPC: H03B19/14
Filed: 1987-06-23
Abstract: PURPOSE: To eliminate the need of a negative power source by grounding the gate terminal of an FET through a high resistance element with respect to DC.  
     CONSTITUTION: A gate bias resistance 10 having a high resistance RG is connected to a gate bias circuit 6. If the fundamental wave signal to be inputted from an input terminal 4 is zero or the signal level is low, the voltage between the gate and the source which is applied to one end A of the resistance 10 is equal to zero and the drain current is equal to the saturation drain current. A forward gate current IG flowing from the gate terminal of an FET 1 to the source terminal is increased according as the input level of the fundamental wave signal is raised, and a voltage equal to RG×IG is applied between the gate and the source of the FET 1. Consequently, since the negative voltage between the gate and the source is automatically impressed to the FET 1 by the resistance 10, the negative power source is unnecessary and a device is operated by a single positive power source.

Filed: 1982-09-09
Abstract: PURPOSE:To rapidly continue a motor in operation by disconnecting a defective bank from the circuit when the defect occurs in one bank of multiplexing configuration, decreasing the speed reference signal, and setting the motor current value to the remaining power converter capacity or lower. CONSTITUTION:AC commercial power is supplied from an input switch 1 through an input transformer 2, rectifiers 3A, 4A and DC reactors 3B, 4B to power inverters 3C, 4C, and fed to a thyristor motor 5. When a defect occurs in the device 3, a voltage control circuit 11 outputs a phase reduction command to the rectifier 3A, and outputs an OFF command from a phase controller 13 to the inverter 3C. Simultaneously, a defect signal is applied to a current value memory comparator 15. The comparator 15 stores the detected input current value, and compares the total input current value immediately before the defect and rated current value per one bank applied from the rated current setter 14. When exceeding the rated constant value, one bank is disconnected, the comparator compares, and controls so that the rotating speed of the motor 5 decreases through a speed limiter 16.

IPC: H01G13/00
Filed: 1991-06-27
Abstract: PURPOSE:To provide the method for forming a terminal electrode which produces no bad conduction of a through hole nor a short across a rear electrode by forming uniformly a through-hole electrode on the surface of an inner wall of the through hole of an insulated substrate having a through hole when forming a terminal electrode of a multielement electronic component or a thick- film hybrid IC. CONSTITUTION:On an insulated substrate 4 having a dividing groove 3 for dividing the substrate into individual pieces and a through hole 2 which, crossing the dividing groove 3, passes through the substrate from the front surface to the rear surface, conductor paste is so printed that a pattern keeps away from intersections between the dividing groove 3 and the circumference of the through hole 2 and the pattern width is smaller in the through hole than in any other parts, getting smaller and smaller as the pattern moves or towards the center of the through hole. At the same time, the conductor paste is sucked from the rear surface. By this method, the conductor paste 1 is stably cut at the center of the through hole 2 where the pattern width is smallest and thereby a through hole electrode can be formed uniformly on the surface of an inner wall of the through hole 2.
