Title: Fixing device for substrate of printed board forming machine
Inventor: MICHIGAMI NORIO
IPC: B23Q3/06
Filed: 1987-09-04
Abstract: PURPOSE:To surely fix a substrate without damaging it by providing a fixed sab-table and movable sub-tables on a table, providing fixed blocks and movable blocks on the fixed sub-tables, providing a movable piece on each movable sub-table, and providing a bush on each movable piece. CONSTITUTION:Out of four reference pins erected on a substrate, a reference pin 26a is fixed between a fixed block 3 and a movable block 4 while fixing a reference pin 26b between a fixed block 11 and a movable block 12, and reference pins 26c, 26d are press fitted into corresponding bushes 21. Then, movable sub-tables 13 are moved in the directions of the arrow B so as to be separated from a fixed sub-table 2 by a distance larger than that of the dispersion between the reference pins. At this time, when a defined tensile force is applied to the substrate so as to prevent the moving quantities of the reference pins 26c, 26d which are press fitted into the bushes 21 from becoming too large, movable pieces 19 are stopped to prevent the breakage of the substrate. Hence, the substrate can be surely fixed without being damaged.

Title: Light receiving circuit
Inventor: YOSHIZAWA NOBUKAZU
IPC: H01L31/0232
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration in band characteristics of a light receiving circuit by connecting the anode or cathode of a light receiving element directly with the signal input pad of a preamplifier chip through extremely short wire bonding and limiting the parasitic inductance component to one point while shortening the connection length thereby reducing the parasitic inductance component. SOLUTION: A chip of a preamplifier 3 is mounted closely to a light receiving element in 1 flush with the plane of carrier 2 mounting the light receiving element. Since the light receiving element is connected directly with the signal input pad of the preamplifier chip through extremely short wire bonding 15, parasitic inductance is limited to one point and self inductance itself is decreased resulting in enhancement of frequency characteristic.

Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To positively perform concentration control of reaction product gas and to remove the reaction product gas to the gas concentration not more than that under a self-imposed control value. SOLUTION: When the detected concentration of a gas detector head 4 is not more than a self-imposed control value, a system controller 25 opens only a damper valve 5 to feed reaction product gas into a scrubber 24 through an exhaust fan 23.
