Title: Plasma adhering device
Inventor: TAKAHASHI CHIHARU
IPC: C23C16/50
Filed: 1984-11-09
Abstract: PURPOSE:To improve the ionization and activation of sputtered metallic particles while increasing target current and bonding speed of particles by means of utilizing magnetron discharge together with ECR discharge. CONSTITUTION:A target electrode is composed of a cylindrical target material 15A, a soft iron ring 15B and a metallic holding ring 15C while the cylindrical target material 15A is connected to a sputter power supply 18. The potential of shield electrodes 16A, 16B and 16C is held at the ground potential to prevent any abnormal discharge from the target electrode and any needless entrance of ion into the target electrode from occuring. In such a constitution, a highly concentrated plasma region in the magnetron discharge mode may be stably formed at low gas pressure near the surface of target in addition to the ECR discharge by means of forming a local magnetic field near target electrode as a target electrode component. Resultantly, the target current may be increased remarkably to improve the ionization ratio of bonded particles further increasing the bonding speed.

Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To compress data efficiently without deteriorating the image quality. SOLUTION: A coding section 3 uses selectively the reversible compression coding or the irreversible compression coding system in the case of conducting compression decoding of digital image data. In the case of compression decoding by using the irreversible compression coding system only, the reversible compression coding system may provide a higher compression rate when the image quality is enhanced. In such a case, the coding control section 7 selects the reversible compression coding system at a high compression rate. Thus, the data are compressed efficiently and the transmission cost is reduced.

Title: Molten-metal dropping device by crucible division of precision casting machine
Inventor: ITO YOSHIMASA
IPC: F27B14/18
Filed: 1987-09-19
Abstract: PURPOSE: To allow the whole amount of molten material to fall at once, and to produce a defect-free casting, by dividing a crucible equally in a circumferential direction, and by forming a hole, through which molten metal is passed, at the central part of the crucible. CONSTITUTION: A casting material 2 is charged in a crucible 3, and this is melted by generating arc discharge with an electrode 1. When the casting material is melted to become molten material 20, it is fallen into a mold. At this time, a solenoid 6 is energized to forward an operation bar 60, and an operation bolt 52 is pushed to remove an engagement part 53 from an engagement part 43. After that, a support member 4 moves in the left direction by a spring 7, and each divided piece 31, 32, 33, and 34 of the crucible 3 is not supported by the support member 4. Thereby, it rotates around a shaft 8 by its own weight, and it moves backward in the direction of radiation, so as to enlarge a bottom hole 35a. Therefore, all of the molten material fall at the central part of the crucible 3 at once. By the above construction, excellent quality casting can be performed without any fear that foreign materials are caught, with a simple mechanism.

Abstract: PURPOSE:To control the deviation from a specified position and to improve the accuracy of the position of a protrusion, by providing stepped down mode recessed part and setting the position protrusion in utilizing the recessed part so that the edge of the protrusion is exposed at the edge surface of the hub. CONSTITUTION:When an annular plate 3 is set to a metal mold and the melted synthetic resin is injected by a molding machine to the cavity of the metal pattern, a protrusion 3b of the annular plate 3 is mated with a positioning recessed part which is relatively deep and provided to the metal mold. Thus the pit can be utilized for deciding the relative position of the metal pattern and the annular plate, and it controls the deviation from a specified position even though there is a fluctuation in the length and size of the protrusion 3b, resulting in the improvement of position accuracy. Also, the synthetic resin filled to both through holes 3c of the annular plate is filled from the upper surface to the lower surface of the annular plate 3 through the through holes 3c, therefore contraction of the part around the through holes 3c at the time of cooling is controlled, and the contact of the hub 2 around both through holes 3c and the annular plate becomes closer, and the accuracy of the area of both reference surfaces becomes more accuracy comparing with the other parts.

Title: Optical scanner
Inventor: MOCHIZUKI KENJI
IPC: G01B11/02
Filed: 1990-09-10
Abstract: PURPOSE:To realize the optical scanner which suits for a high-definition laser beam printer since even a large-NA system can maintain excellent image formation characteristics by sectioning one surface of a scanning lens not in an arcuate shape in a scan vertical direction. CONSTITUTION:When a conventional Ftheta lens which is sectioned arcuately in the scan vertical direction is used, a spherical aberration due to a deficiency in compensation which is caused in the whole optical system is canceled by generating an overcompensated spherical aberration by sectioning at least one surface of the Ftheta lens not in the arcuate shape in the scan vertical direction. Namely, an anamorphic aspherical surface is used as the surface 6 of the 2nd lens 162 of the Ftheta lens 16 on the side of a photosensitive drum and the sectional shape in the scan vertical direction is made not arcuate. Thus, the section in the scan vertical direction is shaped with a specific quadratic curve and the overcompensated spherical aberration is generated to approximate the spherical aberration of the whole optical system to 3 as to light beams of all incidence heights.

Abstract: PURPOSE:To reduce an installation space and to facilitate check and maintenance by moving a door body by rotating a hanging member attached at one end to the body by a rotary driver, operating a protective cover as its counterweight, and sealing with a sealing ring the peripheral wall of an opening. CONSTITUTION:Drivers are operated to rotate a lever 15 for pressing a door body 13 to a sealing ring 7 of the peripheral wall of a conveying opening 6, at a predetermined angle to be opened. Then a motor with a reduction gear brake is operated to rotate a rotary drive shaft 8 to raise the body 13, and to simultaneously lower a protective cover 14. When the cover 14 is moved to a position opposed to the ring 7, the motor is stopped. The cover 14 is pressed to the ring 7 by the rotation of the lever 15 by the drivers. Influence of radiation heat when a material 4 to be treated is passed through the opening 6 is effectively prevented by the cover 14. The cover 14 is also operated as a counterweight of the body 13. As a result, the load of the motor can be reduced.

Filed: 1989-09-14
Abstract: PURPOSE:To enable accurate and secure formation of an isolation groove at an end of a thick thermal oxide film by using the thick thermal oxide film and a deposit oxide film as a mask when etching a groove on a semiconductor substrate. CONSTITUTION:A first thermal oxide film 2 is formed on the surface of a semiconductor substrate 1 and a silicon nitride film 3 is formed thereon. The silicon nitride film 3 is selectively removed to form a thick thermal oxide film 5 of LOCOS part in an area whereto the silicon nitride film 3 is not applied. After the silicon nitride film 3 is removed entirely, a first deposit oxide film 6 is formed. Then, the semiconductor substrate 1 is selectively dry-etched to form an insulation groove A using the first deposit oxide film 6 and the thick thermal oxide film 5 of LOCOS part as a mask. After the first deposit oxide film 6 is removed entirely, a second thermal oxide film 8 is formed on the surface of the semiconductor substrate 1 and a second deposit oxide film 9 is formed. Dry etching is carried out to allow the second oxide film 8 and the second deposit oxide film 9 to remain only in the isolation groove A. Thereby, it is possible to acquire an isolating construction which realizes selfmatching formation of a groove isolating construction at the edge of the thick thermal oxide film 5 of LOCOS part.

Title: Flip-flop circuit with clock signal controlling function and clock control circuit
Inventor: HAMADA MOTOTSUGU
IPC: H03K3/037
Filed: 1999-08-25
Abstract: PROBLEM TO BE SOLVED: To suppress the power consumption of a flip-flop circuit. SOLUTION: The flip-flop circuit 10 is provided with a mismatch detecting circuit DDC and a clock controlling circuit CCC. The circuit DDC detects mismatch between a data input signal DIS and a data output signal DOS of the circuit 10. When the signal DIS and the signal DOS are mismatched, the circuit CCC supplies a short pulse for the circuit 10 as an internal clock signal ICLK by synchronizing with the rising of an external clock signal ECLK. Whereas, when the signal DIS and the signal DOS match with each other, the circuit CCC supplies a low-level signal for the circuit 10 as the signal ICLK. Thus, it is possible to avoid generating of an error in flip-flop operation while suppressing power consumption required for supplying a clock signal.
