Title: Cooling structure provided with bellows and cooling plate
Inventor: SUZUKI SHINYA
IPC: H01L23/40
Filed: 1989-03-16
Abstract: PURPOSE:To separate a bellows from a cooling plate so as to easily maintain a cooling structure and to miniaturize it by a method wherein the bellows, in which a heating element and a cooling medium are enveloped, and a cooling plate, which is provided at such a position that it is brought into contact with the upper plate of the bellows when the bellow expands by heat, are provided. CONSTITUTION:When a heating element 1 starts releasing heat, a cooling medium 2 evaporates to expand to make a bellows extend enabling an upper plate 5 to rise up and to be brought into contact with a cooling plate 7. The medium absorbs the heat of vaporization when it evaporates, whereby the heating element 1 is cooled. Vapor is cooled by the upper plate 5 to be liquidized and returns to the cooling medium 2. The upper plate 5 comes into contact with the cooling plate 7 through which cooling water flows, so that it is cooled and able to liquidize the vapor of the cooling medium 2. As the bellows 3 and the cooling plate 7 are separated from each other, the bellows 3 can be easily replaced. By this setup, a cooling structure of this design can be easily maintained and made small in size.

A release pin 2a pushes out a fixing pin 5 from a slit 1a of the type disk 14, thereby enabling the disk 14, to be rotated. With a 1/10 rotation by the pin 2b, the disk 14 is rotated by 1/10 rotation, whereby 0001 is represented. The release pin 2a is rotated by 1/10 rotation to be disengaged from the fixing pin 5, and the pin 5 is fitted into the slits 1a of the disks 11-14, thereby fixing the disks 11-14. These operations are repeated, and at the 10th run of the operations, a carry through-hole 1c is opposed to the rotary pin 2b, which is fitted through the through-hole 1c into one of recessed parts 1b of the type disk 13 for the second least significant digit. On the other hand, the release pin 2a pushes out the fixing pin 5 to the disk 13. With the type disks 13, 14 rotated by 1/10 rotation, the type disk 14 for the least significant digit is changed to 0 whereas the type disk 13 for the second least significant digit is changed to 1.

IPC: H01H50/04
Filed: 1988-03-16
Abstract: PURPOSE:To prevent ill influence of the electric magnet device side and contact mechanism side upon each other by supporting a resilient film, which separates the electric magnet device side from contact mechanism side in terms of space, at a case accommodating the electric magnet device side and the contact mechanism side. CONSTITUTION:A coupling pin 25 of a left terminal base 2a is pressure fitted in a pin receipt hole 26 of a right terminal base 2b to cause coupling of the two bases 2a, 2b, and thus a case is formed. Inside the case 11 is thus separated into the electric magnet device 10 side and contact mechanism 18 side by a resilient film 22, and two card pieces 19a, 19b are jointed through this resilient film 22. Even though nitric acid is going to transfer to the electric magnet device 10 side associate with arc generation at the opening and closing time of the contacts, the resilient film 22 hinders transfer from the contact mechanism 18 side to the electric magnet device 10 side. This eliminates ill influencing of the two sides upon each other.

Abstract: PURPOSE:To process written information spatially and temporally by writing optical information in a light emitting device array as a light emitting state for transfer of the emission state. CONSTITUTION:An optical signal is incident upon part of a light emitting device array, e.g. a light emitting device T(0) from the outside of a light emitting apparatus to bring the light emitting device T(0) into a light emission state, which is in turn transferred to other light emitting devices T(1)-T(5) of the light emitting device array by application of a transfer clock to clock lines CL1 and CL2. The optical signal is read out optically or electrically on the basis of the emission state of light emitting elements T(1)-T(5) of the transfer destination. Namely, the optical information incident upon the light emitting element array is successively transferred, whereby a delay line of the optical signal is provided. Further, since the optical information flows in the direction of the arranged light emitting elements T(0)-T(5), a serial-parallel conversion function that converts time series information to parallel information is provided. Hereby, written information can temporally or spatially be processed.
