Title: Expansion valve for heat pump
Inventor: YANAGIDA AKIRA
IPC: F25B41/06
Filed: 1989-01-31
Abstract: PURPOSE:To operate a refrigerating cycle with an optimum efficiency, and to prevent the abnormal rise of pressure or decrease in the performance at the time of load variation by controlling the opening of a valve in response to a difference between refrigerant discharge pressure from a compressor to the pressure of a temperature sensing cylinder and the tension of a spring member. CONSTITUTION:Refrigerant is fed from an outdoor heat exchanger 5 to a pipe 7 at the time of room cooling, adiabatically expanded at a valve 45, and then fed to an indoor heat exchanger 3 through a pipe 8. Here, when the overcooling degree of the refrigerant is reduced, the pressure P1 of a first heat sensing cylinder 10a is increased, a diaphragm 41a is displaced downward against the pressure from an equalizer 9 and the tension of a coil spring 46, the valve 45 is throttled at a position until the pressure from the equalizer 9 and the tension of the spring 46 are balanced, the overcooling degree of the refrigerant is increased, and stabilized at a predetermined overcooling degree. On the other hand, if the overcooling degree of the refrigerant is increased, the pressure P1 of a first temperature sensing cylinder 10a is reduced, and the pressure from the equalizer 9 and the tension of the spring 46 are greater, the diaphragm 41a is displaced upward, the valve 45 is opened, the overcooling degree of the refrigerant is reduced, and stabilized to a predetermined overcooling degree.

Title: Ladder type unloader
Inventor: YAMAMOTO TAKU
IPC: B66F11/00
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To eliminate fear of damaging vertical materials, and to reduce weight and cost by forming a step as a traveling guide member. SOLUTION: In this ladder type unloader, a loading space 20 is installed on an aluminum ladder 4 composed of vertical materials 2, 2, a step 3 and guide rollers 7, 7. While sliding members 24, 24 contact with a front face of the step 3 and the guide rollers 7, 7, sliding members 28, 28 contact with the reverse of the step 3. The loading space 20 is vertically moved by a winch and a wire along the step 3 as a traveling guide member by forming the step 3 as the traveling guide member. Thus, the loading space 20 does not contact with the vertical materials 2, 2 of the aluminum ladder 4 by forming the step 3 as the traveling guide member. Fear of generating a scratch in the vertical materials 2, 2 can be eliminated since the loading space 20 does not contact with the vertical materials 2, 2.

Title: Input/output fault recovery processing system
Inventor: TANAKA KOREYUKI
IPC: G06F13/00
Filed: 1986-02-07
Abstract: PURPOSE:To reduce the fault recovery time of a direct access device by comparing the contents of a fault address information file and an index file, and transferring and recovering only a data related to a fault, when the data is recovered after the fault is generated in the medium system of the direct access device. CONSTITUTION:An FD/DK recovery processing part 70 reads in a fault address information file 30 in a DK, and stores an address necessary to be recovered, and checks the necessity of a recovery process by a recovery data 51 written in a set recovering FD40 based on whether a fault address that a DK address represented by an index file 50 stores is included or not. When the fault address is included, and the recovery is required, the recovery processing part 70 reads the recovery data 51 according to the content of the index file, and writes it on the DK. When a write operation is performed normally, a recovered address on the fault address information file 30 is erased. In this way, the transfer of unnecessary data is omitted, and the recovery only for a required part can be executed.

A sufficinetly large voltage can be applied to a photoconductive film 16 to be enabled to obtain high sensitivity in the state that the blooming suppressing condition is satisfied according to the influence of reduced parasitic capacity Cp. The limitation about the second electrode can be satisfied enough when the resistance value thereof is sufficiently large to enable to shield a pulse voltage applied from the gate electrode 13, and moreover in the grade enabled to apply an outside voltage. As the material for the second electrode, polycrystalline silicon, Mo, Ta, W and a silicide thereof are favorable, for example.

Then, a vector data correcting means 5d interpolates and corrects the number of change points of the extracted vector information and a film output means 8 outputs color image data by the plate colors according to noise-removed cutting vector information. Consequently, a cut image printing film can be outputted in a short time.

Filed: 1990-02-01
Abstract: PURPOSE:To relax an electric field in a region deep-depleted by depositing a substance whose work function differs from that of a first gate electrode on the side wall of first gate electrode patterns. CONSTITUTION:Patterns for first gate electrodes 5 are formed in a region on a gate insulation film 4 deposited on a substrate having a first conductive type semiconductor region, a substance whose work function differs from that of the first gate electrodes (The work function is smaller than that of the first gate electrodes 5 in the case of an n channel electric field-effect transistor) is deposited and reactive ion etching is performed. The deposite substance only on the side walls of the first gate electrodes 5 is left, and used as a second gate electrode 6. Then, a second conductivity type semiconductor layer is formed on a region which excludes the part under the third gate electrodes 5 on the surface of the first conductivity type semiconductor. More specifically, in the case of an n channel MOSFET, the second gate electrode which depends on an n type diffusion layer, has a work function smaller than that of the first gate electrodes. This construction makes it possible to relax the electric field in the deep-depleted regions.
