Title: Rear focus type zoom lens
Inventor: IKEMORI KEIJI
IPC: G02B15/173
Filed: 1981-11-26
Abstract: PURPOSE:To obtain the extension amount of focusing lenses based upon the same function for any focal length, by putting a lens system which performs zooming by moving three lens groups on the optical axis in focus through the movement of the 2nd and the 3rd lenses from an object side. CONSTITUTION:A lens system consists of the 1st divergent lens group, the 2nd convergent lens group, and the 3rd divergent lens groups, and for zooming from a wide-angle side to a telephoto side, the 2nd and the 3rd lens groups are moved to an object side. When a beam of light from an infinite-distance point is incident to the 3rd lens at an angle alpha and projected at an angle alpha', alpha/alpha' is a positive value greater than one during zooming, so the drawnout amount of the 3rd group for a short-distance body is invariably constant in an image plane direction. Then, the ratio of movement amount between the 2nd and the 3rd groups during magnification variation is set to 1:0.5-1:1.4, thereby obtaning approximately linear relation between variation in focal length and variation in extension amount.

Title: Display characteristic measurement device for display device
Inventor: HAMAGURI KENJI
IPC: H04N17/04
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce measurement errors due to changes in temperature and moisture. SOLUTION: An image pickup device 2 picks up a measurement pattern displayed on a color display device 4 and the display characteristic is calculated by calculating an image position of a measurement pattern on an image pickup screen from the picked-up image on an image-formed position and a display position on a display screen. An arithmetic parameter, relating to the configuration of an optical system/image pickup system such as a focal distance and a position of an image pickup face with respect to an optical axis, is included in an arithmetic equation of the display characteristic and the temperature characteristic of the arithmetic parameter is stored in a memory 331.  In the case of the measurement, values corresponding to temperature and humidity detected by temperature sensors 217, 227, 219, 229, 220, 230 and humidity sensors 218, 228 around image pickup lenses 211, 221 and 6 CCDs 213, 223 of cameras 21, 22 are set as the arithmetic parameters. A measurement error (arithmetic error) is reduced by setting the arithmetic parameter by taking changes in temperature/humidity into account.

Title: Base material for circuit board, prepreg and printed circuit board using the same
Inventor: KOJIMA TAMAO
IPC: D04H1/542
Filed: 1996-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit board for the high-density packaging, capable of firmly bonding the board to a metallic wiring layer, hardly causing the board warpage and twisting and having high reliability. SOLUTION: This base material for a printed circuit board is formed of a nonwoven fabric 101 comprising staple fibers without manifesting the plasticity at a temperature within the range of 170-300 deg.C under a linear pressure within the range of 10-500kg/cm, e.g. wholly aromatic polyamide fibers and staple fibers capable of manifesting the plasticity, e.g. wholly aromatic polyester fibers. The staple fibers without manifesting the plasticity may mutually be bonded with the fibers capable of manifesting the plasticity. The base material is composed of the resultant nonwoven fabric 101 to thereby more firmly bond the mutual staple fibers without manifesting the plasticity under the same hot- pressing conditions and provide a structure without any fuzz. The thermoplastic resin fibers in the base material is fused by heating to provide mechanically stabler adhesion.  Thereby, the printed circuit board having high reliability can be realized.

Title: Apparatus for controlling movement of carriage unit in serial printer
Inventor: SHINOZUKA HISANOBU
IPC: B41J21/00
Filed: 1985-08-29
Abstract: PURPOSE:To make it possible to increase a printing speed, in backward printing, by controlling the movement of a carriage unit on the basis of the horizontal tab code converted by a code-converting means. CONSTITUTION:A microcomputer 2 performs forward printing on the basis of the printing data from a host computer 4. When the CR code of printing data is read, printing data is temporarily read from RAM 3f and operation for determining a printing direction is performed. Next, when the CR code is read, the possibility of backward printing is judged; when possible, printing data is again temporarily read and, when there is no CR code in said data, the presence of an escape horizontal tab code is judged and, when said code is present, said code id converted to a horizontal code HT and stored. At the time of backward printing, the movement of the carriage unit 1 is controlled on the basis of the HT code. By this method, even if there is a horizontal operation control order in printing data, backward printing can be performed and a printing speed can be increased.

Abstract: PROBLEM TO BE SOLVED: To facilitate the surface pressure adjustment of a bead, the deformation prevention of a cylinder bore and the seal of the clearance between a cylinder liner and a cylinder head by arranging a spacer consisting of a metal plate formed an inner circumferential side thinner than an outer peripheral side to a cylinder hole formed on a gasket constitution plate, in the more inside than the bead. SOLUTION: In a metal gasket 1, a thicker ring shape spacer 5 than a bead plate 2 is inserted in a cylinder hole 3 opened on a gasket constitution plate 2 and a bead 6 with a diameter surrounding the outside of a cylinder liner is formed. The radius direction section shape of the spacer 5 is spot-welded to the gasket constitution plate 2 by making the thickness t1 of an inner circumferential side, namely combustion room side to a value for filling up the step difference between the deck surface of a cylinder body and the upper surface of a brim and thickening the thickness of the outer peripheral edge side 7 slightly.  When the metal gasket 1 is tightened, the spacer 5 fills up the step difference and the surface pressure produced by the spacer 5 is high at the base side of shelf part of the cylinder body and low at the inner circumferential side and so the load added to the base of the shelf part is reduced.
