Title: Plasma cvd device
Inventor: MARUYAMA KAZUMI
IPC: H01L21/31
Filed: 1984-03-28
Abstract: PURPOSE:To discharge electricity among each electrode pair, and to equalize film formation by the discharge by independently controlling supply power at every high-frequency electrode in a plasma CVD device with a plurality of electrode pairs. CONSTITUTION:High-frequency electrodes 12 and substrate electrodes 13 are arranged alternately in a multiple row in the vertical direction, and high-frequency power supplies 15 are connected to each of the high-frequency electrodes 12 and the substrate electrodes. The phase of several power supply 15 is controlled at every power supply by using a regulator 16. Since power applied to separate electrode can be adjusted severally by making the high-frequency power supplies independent in this manner, electricity can be discharged uniformly from each electrode even when the shapes of separate electrode differ. Accordingly, the dispersion of film thickness based on the unevenness of discharge can be reduced.

Title: Vacuum pump with oil-free screw
Inventor: NAYA KOTARO
IPC: F04C18/16
Filed: 1985-03-27
Abstract: PURPOSE:To achieve high vacuum condition with one stage pump by forming a region in which both ends of an operating chamber is closed by the meshing of rotors in a screw type vacuum pump. CONSTITUTION:An operating chamber 65 is filled with gas sucked from an intake port 63 as a rotor is rotated. Further, as the rotor is rotated, the gas charged in operating chambers 67, 70 moves axially with a constant volume since both ends of the operating chamber are sealed with meshing portions 68, 72 of the rotor. When ends of operating chambers 72, 73 contact a discharge side end plate 10, the volume of the gas begins to decrease and soon is discharged from a discharge port. Since two portions between the intake port 63 and discharge port are enclosed by the meshing of the rotors, the gas can be compressed with high compression ratio irrespective of the intake side pressure.

Filed: 1992-03-18
Abstract: PURPOSE:To achieve a reduction in the cost of a device without increasing an amount of electrification of developer and adding an expensive high voltage power source by supplying the grid voltage of an electrifier to the doctor blade of a developing device in parallel. CONSTITUTION:A high voltage is impressed to the wire of the electrifier 1 for a latent image carrier 6, thereby generating corona discharge and producing a voltage at a grid 2 by the ions. The voltage value is set to - several 100s V by the rating of a constant voltage element 10 attached to the grid 2 directly. An electrostatic latent image is formed by irradiating the photosensitive body 6 which is electrified uniformly at almost the same voltage by the voltage of the grid 2, with a laser beam 11 controlled by data. The latent image is formed on the photosensitive body 6 by a developing roller 4 fixed in a developing unit 3 filled with developer. In this case, a voltage impressed to the doctor blade 5 is greater than a developing bias voltage E2 and lower than a grid voltage E1. As a voltage impressed to the doctor blade 5, the voltage of the constant voltage element 10 of the grid 2 is used.

Title: Photosensitive resin composition and photoesnsitive element using that
Inventor: ENDO MASAKI
IPC: G03F7/028
Filed: 1994-03-31
Abstract: PURPOSE:To decrease sludge in the developing process and to increase durability against plating and adhesion property with the base metal by incorporating a specified binder polymer, photopolymn. initiator and compd. CONSTITUTION:The compsn. contains (A) binder polymer having carboxyl groups, (B) photopolynm. initiator, and (C) photopolymerizable compd. having at least one polymerizable ethylene-type unsatd. group in the molecule. A compd. expressed by formula is incorporated as the essential component of the (C) component. In formula, (n)is an integer 1 to 20. Namely, decrease of sludge and improvement in the durability against plating are realized by using the compd. expressed by formula as the main component. The durability against plating and adhesion property are improved because of the presence of benzene rings which increase water resistance, or because of monomers having rather long chains so that when the compsn. is formed into a film, the film has high bending property. On the other hand, since lots of hydrophilic groups -OH-, -(CH2-CH2-O)-, or the like exist, production of sludge is decreased.

Filed: 1988-03-17
Abstract: PURPOSE:To shorten the seeking time and to realize a high-speed access by recording a code including the consistent address information and showing the end of a recording action into a recorded block of an information recording medium. CONSTITUTION:A special code (Z code) including a relevant physical track number and showing a recorded track is recorded on the extended line of an information track before data are recorded. The Z code is added to all written information tracks and therefore the consistent addresses included in all Z codes are used as so-called physical addresses. Therefore a host device, i.e., a CPU 9 records and reproduces the information with use of the physical address or a logical address converted from the physical one. Thus it is possible to improve the information recording reliability and to shorten the seeking time to attain a high-speed access.
