Title: Magnetic disk device
Inventor: HIROSE YOSHIMI
IPC: G11B33/08
Filed: 1989-05-29
Abstract: PURPOSE:To make moment around the center of gravity for a disk enclosure (DE) closed to 0, to suppress instable action to vibration in all directions and to eliminate an error when information are read and written by supporting the DE by two arms at least or a buffer material held by the arm. CONSTITUTION:For inner rubber 3-a and 3-b out of the four kinds of vibration- proofing rubber 3-a - 3-d, when the vibration, etc., is received in X and Y directions, the spring constant of the vibration-proofing rubber is changed so as to suppress the instable action. Accordingly, the size of displacement quantity is adjusted and the displacement quantity is set at the almost same degree for the four kinds of the vibration proofing rubber 3-a - 3-d. Arms 7 protruded from a frame 2 support a DE 1 through a buffer material 8 so as to sandwich upper and bottom surfaces. Accordingly, even when the vibration, etc., is received in a Z direction, vibration energy can be absorbed by sandwiching the position of the largest displacement quantity or a part near the position by using the arms 7. Thus, when the information are read and written, the error is prevented from being induced by the instable action.

Title: Exposure apparatus
Inventor: NAKAGAWA KUNIHIKO
IPC: G03F7/20
Filed: 1977-11-14
Abstract: PURPOSE:To shield photo resist from air and make possible exposure without using any high vacuum vessel or the like by rotating a video desc being a recording medium and flowing an inert gas from the center thereof toward the outside circumference thereby forming the film of the inert gas on the surface. CONSTITUTION:The inert gas 110, having been removed of dust by being passed through a filter 12, is sent to the surface of the photo resist 4 on a disc 1 from a suction port 9 through gas pipe. When a motor 6 is run in this state, the surface inert gas laminar flow having a flowline 111 produces on the surface of the rotary disc 1. Since the disc 1 and back plate 10 are in proximity, the inert gas existing therebetween is forced out in the radial direction by centrifugal force, whereby the laminar flow of the inert gas 110 is continuously formed on the surface of the photo resist 4. The photo resist 4 is then shielded from air by the film of the inert gas 110. At this time, production of turbulence is prevented by the exhaust port 14 provided to part of the housing structure. The photo resist 4 is then sensitized by light 5 for resist exposure.

Filed: 1991-06-10
Abstract: PURPOSE:To provide a compact and highly reliable fuel cell power generating system by dividing a cooling water system into a primary system and a secondary system, and constituting the systems into a closed system. CONSTITUTION:A cooling water system IC absorbs the heat energy by the generating reaction of a fuel cell body 1 by circulating a cooling water. The cooling water is guided to a condenser/steam separator 3. The detection signal of a pressure detector 15 is returned to the flow rate control valve 16 of a secondary cooling water system to keep a determined pressure. A cooler 3B controls the water quantity by a control valve 18 to hold the value of a temperature detector 17 at a determined value. The secondary cooling water system including a steam separator 4 is set to a pressure lower than the primary cooling water system. The pressure is detected by a detector 21 to regulate a valve 22, and the back pressure on a refrigerator 6 side is kept at a standard value. The separated steam is guided to a reformer 22 and utilized in the refrigerator 5 as steam. The resulting returned water is purified by a treatment device 6 and returned to the secondary cooling water system by a pump 33. The detection signal of a water level detector 23 is returned to a regulating valve 24 to keep the water level constant. Thus, water pollution is never caused, and the system can be made compact and reduced in cost.
