Title: Method for filing up bottomed hole of wiring board
Inventor: KUROKAWA SATOSHI
IPC: H05K3/46
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To fill up the bottomed hole of a wiring board without using any form plate. SOLUTION: Balls 7 are put on a wiring board having bottomed via holes 5 so that the balls 5 may be spread all over the surface of the board. Consequently, the balls 7 are supplied into the holes 5. In this point of time, however, gaps are formed between the holes 5 and balls 7, because the balls 7 have spheric shapes. After the balls 7 are supplied into the holes 5, the balls 7 are melted. When the balls 7 are melted, the gaps between the holes 5 and balls 7 are filled up. Thus the via holes 5 can be filled up without using any form plate.

IPC: F16C7/00
Filed: 1981-12-17
Abstract: PURPOSE:To permit alloying of a connecting rod with Al without deteriorating the durability of said connecting rod by forming a reinforcing part bulged outside, on the connecting rod made of a material having a larger thermal expansion rate than that of a piston pin.

Title: Focus control circuit
Inventor: NAGASAWA MASAHITO
IPC: G11B7/09
Filed: 1987-08-18
Abstract: PURPOSE:To stabilize a loop gain and to stably execute focus control operation by holding an error signal for focus control at a value before the change of a laser outgoing power during a setting time while the laser outgoing power is changed. CONSTITUTION:A sampling pulse 20 detects the change of the laser outgoing power in a frequency area, to which a focus control circuit responds, earlier than the focus control circuit to respond. Therefore, since a sampling is executed to the output of a variable gain amplifier by a sampling pulse 20 and a sample value is held by a hold pulse 19, the turbulence of a servo due to the change of the laser outgoing power to accompany a switching from a reproducing mode to a recording mode or from the recording mode to the reproducing mode can be prevented. Thus, the turbulence of the loop gain is prevented, the operation of a focus servo system can be stabilized and prescribed focus servo control can be stably realized without fail.
