Title: Thermocompression bonding method for electronic parts having solder bump
Inventor: SATO SEIICHI
IPC: H05K3/34
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To eliminate loss time during thermocompression and improve productivity by pressing a solder bump to an electrode on a substrate and raising the thermocompression bonding tool, by judging that the solder bump has been melted if the load detection value decreases below a predetermined value by load detection means after the start of heating of electronic parts. SOLUTION: A thermocompression bonding tool is lowered and the electronic parts are pressed to a footing. Height position A of the thermocompression tool in the thermocompression bonding process is shown in a graph. A decreased value in a detection load by a load cell, that is, the thermocompression load B is shown in B. Also, timing C of ON-OFF for applying a current to a heater for heating the solder bump of the electronic parts above the melting point temperature of solder is shown. At timing t2, one bump of the electronic parts are contacted to an electrode as shown in (a). If a detected load value by the load detection means decreases below a predetermined value after starting the heating of the electronic parts, then the solder bump is judged to have been melted, and the thermocompression tool is raised.  By doing this, it is not necessary to wait time-up of a predicted melting time.

Title: Cut paper accommodating cassette and mounting/ demounting method of casette
Inventor: HIRAGA HIROYUKI
IPC: B65H3/52
Filed: 1986-12-25
Abstract: PURPOSE:To separate and transport a cut paper certainly and easily by arranging supporting means for supporting a separating lever in swingable way onto a casette body at the other edge. CONSTITUTION:A separating lever 15 is separated from a guide, accommodated with the lowering of a loaded paper P, and a separating plate 16 is attached onto the rear edge upper part of the uppermost paper P1 by only the dead weight having the moment force of the separating lever 15. In the transport process, a paper feeding roller 18 revolves a pulse motor in the normal direction to an initial position alphao. Therefore, a rubber part 18a acts reversely to the case of separation, and the front edge of the uppermost paper P1 is transported to a paper initial position Xo over a front pressing part 2d. Since, at this time, the rear edge part of the uppermost paper P1 is outside a gap (t), generation of the defect caused by the contact between the gap part and the load which is applied onto the uppermost paper P1 during the passing through the gap can be prevented in the succeeding transport, and stable transport is permitted.

Filed: 1994-12-12
Abstract: PURPOSE: To improve rigidity of a rear beam by reducing an opening of the rear beam as well as compacting the circumference of a valve by making an axis of a discharge port roughly vertically downward. CONSTITUTION: Discharge ports 14, 15 are arranged downward on a rear part lower part of a control valve unit 5, and discharge pipings 41, 42 are connected to them. Consequently, the discharge pipings 41, 42 are below a rear beam 51 and do not make contact with the rear beam 51, and accordingly, an opening 51a becomes roughly the same as before in shape and size at a part adjoining to the control valve unit 5. Additionally, as the discharge ports 14, 15 are on the left side of a steering valve unit 30, a space equivalent to a hatching part X on the right side of this steering valve unit 30 can be saved, the opening 51a can be reduced and rigidity of the rear beam 51 can be improved. Additionally the discharge pipings 41, 42 can be shortened in piping length between the discharge ports 14, 15 and a piping connecting part of a cylinder 21.

Inventor: NAKAGOME SEIJI
IPC: G02B6/00
Filed: 1989-11-28
Abstract: PURPOSE:To prevent the release of the clad member from the core member even if the optical fiber is drastically deformed by specifying the 100% modulus value of the core with respect to that of the core member. CONSTITUTION:The core member and clad member of the optical fiber are formed with cross-linked silicone rubber. In this case, a cross-linked silicone rubber with the 100% modulus value controlled to about 80-140% of that of the core is used for the clad member. When the diameter of the optical fiber is controlled to 0.5-3.0mum, the thickness of the clad member is controlled to about 50-200mum. Even when such an optical fiber is used where repeated deformation and drastic deformation are required, interface release, cracking, etc., are not generated because of the difference in elasticity between both materials, and interface release is prevented.
