Title: Integrated circuit utilizing peltier cooling method
Inventor: MASUBUCHI HIDEO
IPC: H01L23/38
Filed: 1985-01-26
Abstract: PURPOSE:To enable the fellow individual IC substrates to house in the case body at intervals one-severalth narrower than the conventional ones, and at the same time, to prevent heat from affecting the operation of the IC even though the integration degree of the IC itself is enhanced by a method wherein a cooling method according to the Peltier effect is utilized. CONSTITUTION:This integrated circuit is formed in such a constitution that a Peltier cooling is generated at a place, where is near individual circuit main bodies 2 and is such a place as to come into contact to the interior of an element 1 or the IC element; the heat radiating part is made to locate on the upper side of the partition plates, which are about 1cm away from the main body substrate and are formed in such a way that the heat generating parts only of the individual IC circuits protrude thereto; and the heat of the heat generating parts is made to radiate at the heat radiating part. As the cooling is one to cool locally the necessary parts in the IC, the inferiority of efficiency of the thermoelectric cooling method does not exert effect so much to the cooling effect. Moreover, when the parts other than the IC circuits are made in a heat-resisting manner, the partition plates, the fans and the heat pipes can be omitted and even when the temperature in the interior of the element rises higher than the normal one, the IC can be made to operate without being subjected to the effect functionally.

Abstract: PURPOSE:To increase the utilization rate of a precious material by opposing a pair of conductors which are made by contracting a conductor in the axial direction, swelling the diameter in the diameter direction, and forming diameter expansion contacts, near the end of a rod-form elastic conductor whose section is circular, and making the diameter expansion contact to the peripheral surface of the base of the other side elastic conductor. CONSTITUTION:A plug 2 is made in a male structure furnishing a projecting shaft 4 at the tip, and a socket 3 is made in a female structure furnishing a hole 5 to gear with the shaft 4. The contact ends 6a and 8a of both contact makers 6 and 8 have the same structure, and diameter expansion contacts 6d and 8d made by contracting the ways of wiry basic conductors 6c and 8c in the axial direction and swelling the diameters are provided. When they are connected, a resistance is generated and a click feeling is obtained when the diameter expansion contacts 6a and 8a cross over each other. And, even though the plug 2 and the socket 3 are going to separate spontaneously owing to a vibration and the like, the resistance when the diameter expansion contacts 6a and 8a cross over each other prevents the pulling-out of them. In this case, the contact of the contact ends 6a and 8a are made at two points, and a positive contact is secured.

Title: Ball bearing device for swing arm
Inventor: SAKATANI IKUNORI
IPC: F16C25/08
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To increase the stability in the control of a swing arm system to achieve a high speed and high precision in its control by differing the rigidity of radial bearings in two directions in which ball bearings cross at right angles. SOLUTION: Two ball bearings are fixed in such a manner that an outside diameter face is apart from an inside diameter face of a cylindrical housing 7 of a magnetic disc device in the axial direction and the inside diameter face is fitted in a shaft 9 fixed on a base 15. When the housing 7 is used as an oscillation member by fixing its shaft in this way, a track face of an outer ring 6 on a side which is attached to the housing 7 is machined into an elliptical shape so that the axial direction of an arm and a short axis of an ellipse become parallel mutually at all times even if a swing arm 3 oscillates. In this way, when the track face is machined into the elliptical shape in advance, the track face is kept in the elliptical shape even if the ball bearing 1 is used by fitting into the housing 7 and the shaft 9 through a clearance.  Consequently, it is possible to provide higher rigidity of a radial bearing in the direction of short axis than the rigidity of a bearing in the direction of long axis which crosses the radial direction on one side at right angles.
