Title: Method for mounting ball
Inventor: TAKEUCHI MASAO
IPC: H05K3/34
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To reduce a mounting miss of a ball having a diameter of a specific range on a work piece by setting the degree of vacuum when a specific number of non-chucked holes each of which does not yet chuck the ball in the step of vacuum chucking are retained to a specific range. SOLUTION: An evacuation capability of a vacuum pump 10 is controlled so that the degree of vacuum when one non-chucked hole which does not yet chuck a ball is retained becomes 200 to 560 mmHg. A diameter of the ball is set to 0.02 to 0.5 mm. When the degree of vacuum of a cavity 6 exceeds 560 mmHg in a vacuum chucking step, an atmospheric pressure difference of the cavity from the atmosphere becomes less than 200 mmHg, probability of chucking the ball per unit time to the chucking hole is reduced, and is hence not practical. Meanwhile, when the degree of vacuum of the cavity 6 is less than 200 mmHg, a speed of the air to be chucked to the hole is excessively accelerated, the ball is rapidly collided with the hole, a part of the ball is bitten into the hole, fixed, and scarcely separated when the ball is transferred to a work piece 12.

Title: Reproduction characteristic controller
Inventor: NAGATA YUICHI
IPC: G10K15/00
Filed: 1994-07-07
Abstract: PURPOSE:To prevent the frequency characteristic according to a use status from collapsing even if a tone quality adjustment is performed. CONSTITUTION:Two-band tone control circuits 40 to 43 are adjusted and the tone quality of the sound to be heard from each speaker is adjusted. This tone quality becomes the one affected by the characteristic of a speaker and the status of a room. Therefore, the setting of the frequency characteristic according to a use status can be performed by adjusting this tone quality. If an amplification is performed in this state, the reproduction of musical sound is performed by the frequency characteristic compatible to the use status. If the knobs for gain adjustment of two-band tone control circuits 21 L and 21 R are turned on, the tone quality is changed to the tone quality according to the gain but the gain of the two-band tone control circuits is not changed. Therefore, as for the frequency characteristic corresponding to the use status, the state at the time of the adjustment is excellently maintained.
