Title: Semiconductor element mounting method and apparatus thereof
Inventor: TAKAMURA KEIJI
IPC: H01L21/60
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor element mounting device, capable of completing highly accurate connection through self-alignment effect. SOLUTION: A connection circuit substrate 4 is mountably fixed on a substrate holding part, and then a vacuum source 12 is driven so as to vacuum chuck fix the backside of a semiconductor element 1 on a mounting arm 2 using an cucktion hole 16. Next, solder balls 6, 6 are aligned with solder bumps 18, 18 on electrodes 3, 3 of the semiconductor element 1 by an XYθ stage 14. Next, the mounting arm 2 is lowered by a Z-axial drive part 7, until the semiconductor element 1 arrives at the position wherein the solder balls 6, 6 make contact with the solder bumps 18, 18. Thus, a pin 8 is pressed down against the backside of the semiconductor 1 by a VCM 10, so as to release the vacuum chucking of the semiconductor element 1 for completion of the mounting of the semiconductor element 1.  Later, the solder balls 6 and solder bumps 18 are melted down from heating a hot plate 15, thereby enabling a highly accurate electrical connection to be completed by self-alignment effect.

Title: Method and mechanism for positioning slit
Inventor: KANEKO TSUTOMU
IPC: G01J3/04
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To position a slit easily and accurately by setting the longitudinal direction of a slit at a specified angle with respect to the moving direction thereof at a position where the slit intersects an optical path. SOLUTION: A slit unit is set at a specified angle α1 in the longitudinal direction of a slit 1a with respect to the moving direction thereof at a position where each of slits 1 has different width made in a slit plate intersects an optical path. In such an arrangement, a motor turns a gear to rotary drive the slit plate thus arranging the slit 1a on an optical path. In that state, distance x1 is not equal to distance x2. When the slit plate is turned by an angle βfrom that state, the slit 1a is shifted to a position shown by a phantom line and a distance x1'=x2' is satisfied. Consequently, the slit 1a can be positioned accurately with respect to the optical path just like the slit 1a is shifted laterally by a distance Δx1.

Title: Method for controlling fluid coupling or torque converter
Inventor: TAKEUCHI HIROAKI
IPC: F16H45/02
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To improve responsiveness of lockup control during inertia running. SOLUTION: When lockup control is performed during inertia running, a pressure of working fluid fed to a torque converter is boosted through pressure reduction regulation of a secondary regulator 52 or combination of pressure reduction regulation of a primary regulator 50 and the secondary regulator 52. The primary regulator 50 is a valve to regulate a pressure to a value responding to the output of a prime mover and regulate it to a low value during inertial running. With the internal pressure of the torque converter increased, a differential pressure is produced between the surface and the back of a lockup piston 40 by a control valve 56, and the lockup piston 40 is connected. A current differential pressure is a value equal to a differential pressure during drive running.
