Title: Multicolor lithographic offset press
Inventor: ONO HIDEJIRO
IPC: B41F3/04
Filed: 1993-12-27
Abstract: PURPOSE:To obtain a multicolor lithographic offset press capable of producing a color filter having a surface smoothness in a short printing process by transferring an image of each printing plate to a glass substrate through a blanket cylinder at a time. CONSTITUTION:Firstly, a plate cylinder 1 is rotated, and ink is supplied to printing plates 1-1, 1-2, 1-3 respectively from form roller groups 2-1, 2-2, 2-3. A blanket cylinder 3 is rotated in contact with the plate cylinder 1. While the plate cylinder 1 is rotated once and the blanket cylinder 3 is rotated three times, images of three colors on the printing plates 1-1, 1-2, 1--3 are formed on the blanket cylinder 3 at a time. As a travel frame 7 is lowered, the blanket cylinder 3 is separated from the plate cylinder 1. The travel frame 7 starts moving rightward, and the blanket cylinder 3 rotates on a glass substrate 5 in pressure contact states. In this manner, the image on the blanket cylinder 3 is transferred to the glass substrate 5. Thus, images of three colors are simultaneously printed.

Patent JP-H07189929-A (JP)
Title: Scroll compressor
Inventor: TAKEBAYASHI MASAHIRO
IPC: F04C18/02
Filed: 1993-12-27
Abstract: PURPOSE:To reduce a flow rate leaking from the axial clearance of a scroll compressor so as to increase the compressor efficiency and prevent mutual contact of scroll members so as to increase the reliability of the compressor. CONSTITUTION:A non-rotary scroll 2 is supported by a housing 12 so as to be transferable in the axial direction and a rotary scroll 3 and the non-rotary scroll 2 are pressed to each other so as not to come into direct contact with each other and force to slide mutually through a sliding member provided on the lap end face between the rotary scroll 3 and the non-rotary scroll 2. In this way, since the face between the lap end faces of both scrolls 3, 2 and the groove bottom face holds the sliding member and slides with little clearance, the flow rate of a coolant leaking from the clearance is reduced and the compressor efficiency can be increased. Since both scroll members are pressed on each other through the sliding member, seizure or the like can be prevented even when two materials, which do not slide well mutually, like aluminum are combined together and hence, the reliability can be increased.

Title: Manufacture of tape carrier
Inventor: ENDO HIROHISA
IPC: B23K26/351
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of cracks resulting from burrs produced when a solder ball is mounted and, in addition, to carry out the mounting work in a short time, by removing the burrs produced around a through hole with a laser beam after the through hole is formed through a tape by punching. SOLUTION: A through hole 3 having a perpendicular inner peripheral wall to a tape 1 is formed by punching using a molding die having a punch and a die. When the hole 3 is formed, burrs are produced around the hole 3 on the rear surface side. Therefore, the burrs are removed by irradiating only the area surrounding the hole 3 with a laser beam. Consequently, the mounting of a solder ball on the hole 3 on the rear-surface side of the tape 1 becomes easier, because the edge 3a of the cross-section of the hole 3 on the rear-surface side of the tape 1 becomes to have an inclined inner peripheral wall due to the laser beam. Accordingly, occurrence of cracks can be prevented when the solder ball is mounted and, the mounting work can be carried out in a short time.

CONSTITUTION:A hinge comprises a coupling member 2 removably engaged with a base body 1 to cover the base body therewith and a hinge body 3 engaged with the coupling member to cover the coupling member therewith. A base body 1 is securely embedded in a side wall A and a cup 42 of the hinge body 3 in a door B. A body member 41 of the hinge body 3 and the coupling member 2 mounted to the body member 41 are mounted to a door B in a manner to be engaged in a covering manner with the base body 1. In this state, plates 46 on both sides of the body member 41 are positioned and locked to the base part of the base body 1, and floating of the body member 41 is prevented by a lock lever 21 rearwardly energized through the force of a spring 28 to secure the body member. In removal, a release operating part 24 of the lock lever 21 is pushed forward against energization of the spring 28 to release the coupling member 2 from lock. This constitution simplifies mounting and demounting of the hinge body mounted to the base body through the coupling member.

The replacement and the adjustment of the lever 5 are performed at the outside of a vacuum device.  After the adjustment, a slider 13 of a sensor part device 12 is held and conveyed in the horizontal direction by a transfer rod and mounted on the measuring position from the opening of the outer-frame mounting part of an apparatus vacuum chamber. Then, the lever 5 is brought close to the sample, and the sample is measured by an FAM.

IPC: G06F12/00
Filed: 1988-12-28
Abstract: PURPOSE:To attain an effective reformat operation even though a disk memory is kept in an on-line state by controlling a data buffer and a time measuring means via a main control part and effectively functioning the buffer and the measuring means. CONSTITUTION:A counter 15 serving as a time measuring means counts the machine clocks of a controller 10, and the count value of the counter 15 is read by a microprocessor 11 and also reset. The microprocessor 11 reads a disk number and an executing track address out of a control memory 13 to select a disk memory 30 defined by the disk number and to position a head mechanism to the track defined by the executing track address. Then all record information on the track are read out and stored in a data buffer 14 and then read out of the buffer 14 to write them again onto the track. Thus it is possible to secure a sufficiently effective reformat operation even though the memory 30 to undergo the reformat operation is kept in an on-line state.

Abstract: PURPOSE:To extend the service life until a fixing roller becomes unuseable due to an offset by cleaning the fixing roller by a fibrous cleaning member containing a polishing grain. CONSTITUTION:A recording material 13 which has carried an unfixed toner image 12 is allowed to pass through between a fixing roller 1 and a pressure roller 4.

Abstract: PURPOSE: To improve ohmic contact characteristic by solving the problem of selectively removing emitter by incorporating a first bipolar transistor containing an etch stop layer, adjacent to both the emitter region and base region and a collector region, a second device and a coupling portion between the transistor and device. CONSTITUTION: Six layers are grown on a semiinsulated GaAs substrate. GaAs and Alx Ga1-x As are generally etched anisotropically at a rate of 1000 angstroms per minute, but it is clear that Iny Ga1-y As is etched at a rate 10 angstroms of less. By the presence of In, etching is stopped at a 4th layer, and overetching permits controlled undercut of an emitter contact 142. A base contact 144 is formed by the vapor deposition and lift-off of Zn:Au/Au or Ti/Pt/Au on an Iny Ga1-y As layer 139. A photoresist 149 is turned and stuck, and a pattern for an opening portion is drawn for determining the position of collector-contact 146 (and collector 136 and the edges of bases 138, 139).
