Filed: 1980-03-05
Abstract: PURPOSE: To cancel the pressures in the radial direction which a plane slide valve and a valve holder receive by pressure fluid and to keep satisfactory airtightness by a method wherein symmetrically on the diametrical line of a trip rod, the valve seat surfaces of two plane valve seats are arranged in parallel facing each other.  
     CONSTITUTION: At symmetrical positions on a diametrical line of the trip rod 13, plane valve seats 17, 18 are arranged in parallel letting the valve seat surfaces 19, 20 face each other. In this way, pressures are applied to plane slide valves 21, 22 and a valve holder 25 through pressure fluid in the radial direction but they cancel each other. The plane slide valves 21, 22 are pressed against the plane valve seats 17, 18 by the pressure due to the difference of the pressure areas between end faces 30, 31 on an inlet port side and the end face on a valve holder 25 side. As a result of it, the plane slide valves 21, 22 can hold their own position without special position-holding means, be attached closely to the plane valve seats 17, 18, be driven in slight operating force and satisfactory airtightness can be kept between the valve seats 17, 18 and the slide valve 21.

Abstract: PURPOSE: To reduce the temperature change due to the sharp change in the quantity of insolation, by dividing a sunlight collector into a feed water heating evaporation section and a superheating section and providing a valve between both the sections and connecting an accumulator circuit to the valve.  
     CONSTITUTION: Water is supplied from a feed water pump 1 into an accumulator 8 through an evaporation pipe 3' of a first sunlight collector 2' and the valve 9a. The water part, which is not evaporated at that time, is reserved in the accumulator. The saturated steam, which is the evaporated water part, is conducted to a second sunlight collector 2" through a valve 9c and is heated by a superheating pipe 3" and then conducted into a regenerator 4. The steam temperature in the first sunlight collector 2' is maintained within a saturated temperature range dependent on the feed water temperature and the operation pressure. Thus, the temperature of the evaporation pipe 3' is always limited within a small range even if the quantity of isolation changes sharply.

Title: Method for detecting transport limitation of magnetic head transport device
Inventor: FUJIISHI YOSHINOBU
IPC: G11B21/10
Filed: 1989-02-09
Abstract: PURPOSE:To improve working efficiency for servo write by repeating an operation to write a servo pattern when no servo pattern is read out by performing the preset track pitch transportation of a magnetic head until arriving at transport limitation. CONSTITUTION:The magnetic head 2 at an arbitrary position on a magnetic disk 1, the entire plane of which is erased, is transported as reading the servo pattern with a track pitch set in advance on either the inner peripheral side or the outer peripheral side, and when no servo pattern is read out at that track position, the servo pattern is written on that track position. Next, the servo pattern is read by performing the track pitch transportation set in advance again, and the operation to write the servo pattern when no servo pattern is read out is repeated. And the position where the servo pattern is read out first is set as the one where a magnetic transport device arrives at the transport limitation by abutting with transport limitation regulating means 30 and 31. Thus, the working efficiency can be improved by automatically performing the transportation of a swing arm in its own system.
