Title: Sputtering device
Inventor: ISHIHARA YOSHITAKE
IPC: C23C14/34
Filed: 1986-12-17
Abstract: PURPOSE:To form a sputtered film which is improved in step coverability by providing an ultrasonic oscillator to a jig for supporting a substrate and applying oscillation to the substrate during formation of the sputtered film. CONSTITUTION:An oscillator holder 14 disposed with the ultrasonic oscillator 17 in the central part is brought into tight contact with the substrate 18. The holder 14 is pressed by a spring 16 to the substrate 18 to press said substrate to the front end face of a substrate holder 15. Sputtering particles are released in this state from a target 12 and the ultrasonic oscillator 17 is driven to apply the perpendicular oscillation to the central part of the substrate 18. Since the periphery of the substrate 18 is fixed, the substrate makes curved oscillation and the sputtering particles released from the target 12 enter the substrate 18 from all angles. The kinetic energy increases relatively as well and the step coverability is improved. The uniformly flat sputtered film is thus formed on the semiconductor substrate or the like having the fine steps on the surface.

Abstract: PURPOSE:To raise a printing speed by providing an interpolating means and by generating pixel data of an even-number field by an interpolation method on the basis of the pixel data extracted from an odd-number field or the even- number field. CONSTITUTION:A line interpolation circuit 28 provided in the rear stage of a color process circuit 26 generates pixel data Y2,j, Y4,j, Y6,j,... Y512,j on a j-th line of an even-number field by an interpolation method on the basis of pixel data Y1,j, Y3,j, Y5,j,... Y511,j on the j-th line of an odd-number field. Thereby the pixel data for one line are completed, and these pixel data are given to a printing means (head 50) to make it execute printing for one printing line. Since the pixel data for printing of one printing line are completed in a one field period in this way, a time required for printing can be shortened. Accordingly, the pixel data can be so given as to follow a printing speed on the print head side, and thus the printing speed can be raised.

Title: Base plate for direct drawing type planographic printing
Inventor: KATO EIICHI
IPC: G03G7/00
Filed: 1990-11-13
Abstract: PURPOSE:To well suppress the generation of background staining and to also impart good printing durability by forming an image receiving layer using a binder containing at least either one of a fluorine atom and a silicon atom as a main component. CONSTITUTION:A binder resin is composed of a graft polymer consisting of a segment A being a polymer component containing a functional group having a hydrophilic group protected by a protective group containing a fluorine atom and/or a silicon atom and forming the hydrophilic group upon decomposition and a segment B being a polymer component corresponding to a monofunctional macromonomer. The graft copolymer is different from a random copolymer to have peculiar behavior in an image receiving layer. That is, when the resin is independently used as the main component of the image receiving layer, it is estimated that a microphase separation structure is formed by the difference in the compatibility of the segment A with the segment B and, further, since there is such a tendency that the segment A forming a hydrophilic group later is much present in a surface layer part, the effect enhancing the hydrophilicity of a non-image part is more enhanced and the hydrophilicity of the non-image part is clearly discriminated from that of an image part.

Title: Cryopump
Inventor: SUZUKI TAKASHI
IPC: F04B37/08
Filed: 1989-11-21
Abstract: PURPOSE:To easily determine a normal/abnormal state of working cycles in a cryopump so as to generate a warning in an early stage by counting cycles of compression and expansion in a freezer by a sensor. CONSTITUTION:In a freezer of a cryopump, its very low temperature panel 1 is constantly cooled during operation by opening/closing of high and low pressure valves 2, 3 and reciprocating motion of an internal piston 4. When impurities 10 are condensed on an inner wall of a cold head cylinder 9, a slide occurs inside a cold head motor 5 and its rotating motion is not completely converted to reciprocating motion of a cam follower 6. In this case one cycle of the reciprocating motion in the internal piston 4 which is interlocked with the cam follower 6 is sensed by a sensor 7 and one cycle is counted by a pulse counter 8. By comparing pulse count numbers during a normal state and during operation, the state of working cycles is determined.
