Title: Sealed type magnetic disk driving device
Inventor: SUGA MASAYUKI
IPC: G11B33/12
Filed: 1986-12-01
Abstract: PURPOSE:To prevent highly accurate positioning from obstruction between a disk and a head due to the change of an external pressure by coupling a member to receive the external pressure and a member to hold correctly the relative position of the head and the disk in using as another body member, with a soft member. CONSTITUTION:A heat 5 and a disk, 4 are fixed respectively to an actuator 3 and a spindle motor 2 and the actuator 3 and the spindle motor 2 are fixed to a single body base 1. An enclosure 9 is of a complete closed structure and the power source and a signal cable only necessary to drive and control the actuator and the spindle motor are extracted through a packing to an external part. When an outside air pressure is changed, the pressure difference occurs inside and outside the enclosure, and therefore, the enclosure 9 is changed, and since a vibrationproof rubber 7 is arranged between the base and the enclosure, the deformation of the enclosure is absorbed wholly by the change of the vibrationproof rubber and the deformation is not inflicted on the base 1.

Title: Liquid-cooled flat semiconductor device
Inventor: NOMURA TOSHIHIRO
IPC: H01L25/11
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To reduce a thermal stress at a solder joint part to a semiconductor, etc., for reduction in size and weight by comprising a power semiconductor chip and a flat thin-wall metal cooling body wherein a cooling liquid flows inside. SOLUTION: Silver soldering is performed with, for example, metal pipe 11 and 12, a copper base 2, and a molybdenum plate 3, etc., to form a flat thin-wall metal cooling body. The molybdenum plate 3 is so used as to match its coefficient of thermal expansion to that of a silicon semiconductor chip so that degradation due to heat cycle of a solder caused by soldering to the chip is prevented. The copper base 2 requires, for assuring a channel for a cooling water, an outer frame 2a and a rib 2b. To suppress a thermal stress caused by a difference in coefficient of thermal expansion to molybdenum to a small amount, the thickness of the outer frame 2a and that of the rib 2b are sufficiently thin.  It is important that many pillars 2c are provided midway, and thanks to this, a contact area to water increases, and a turbulence is generated, though water flow is hindered, so that thermal resistance to the water is lowered.
