A swash-plate, plunger-type hydraulic pressure apparatus, which may operate as a hydraulic pump or motor, includes a cylinder block, an annular array of plungers slidably held in the cylinder block, a swash plate, a plurality of shoes angularly movably coupled respectively to the ends of the plungers, and a retainer plate mounted adjacent the swash plate and holding the shoes in slidable contact with the sliding surface. The shoes have respective annular grooves defined in the outer cylindrical surfaces thereof. The retainer plate has a plurality of shoe holding holes defined therein and a like plurality of cutout openings extending from the holes. The shoe holding holes communicate with one of outer and inner circumferential edges of the retainer plate through the cutout openings, respectively. The cutout openings have a width slightly larger than the outside diameter of the annular grooves, whereby the annular grooves can be inserted into the shoe holding holes, respectively, through the cutout openings.

Disclosed is a method for the formation of a thick silicon oxide film which is insoluble in organic solvents and free of cracks and pinholes on the surface of a substrate. The method comprises forming a hydrogen silsesquioxane resin film on the surface of a substrate, converting the hydrogen silsesquioxane resin into preceramic silicon oxide by heating in an inert gas atmosphere, and converting the preceramic silicon oxide into silicon oxide ceramic by heating in an atmosphere selected from the group consisting of oxygen and oxygen mixed with an inert gas.

A multi-chamber heat-pump type air conditioner in which a plurality of room units (2, 3, 4) are connected to one heat source unit (1), cooling and heating can be effected selectively for each room unit (2, 3, 4), and cooling can be effected by one room unit and heating can be simultaneously effected by another, wherein the high-level pressure or low-level pressure is controlled from rising high as compared to the time of normal operation, and the reliability of the compressor (17) is improved. In which, a third pressure-detector (48) is provided for detecting a rise in pressure between a compressor (17) and a four-way changeover valve (18), and a control circuit (49) is provided for controlling such that, in the event that the pressure within the pipe is below a predetermined pressure, a sixth valve (45) and a seventh valve (46) are closed, while in the event that the pressure within the pipe exceeds the predetermined pressure, the sixth valve (45) and seventh valve (46) are opened.

In an element forming region isolated from other regions by a field oxide, one select transistor and a plurality of MOS transistors are connected in series so that a source/drain diffusion region is commonly owned by two neighboring transistors. The gate electrodes of the MOS transistors are connected to the lower electrodes of ferroelectric capacitors, respectively. The gate electrode of the select transistor, and the lower electrodes and upper electrodes of the ferroelectric capacitors are led out as word lines. A metal wiring which serves as a bit line is connected to a drain diffusion region.

A figure editing apparatus for editing figure sets each comprising a set of a plurality of basic figures includes a first memory for storing, in correlated form, each figure set and the plurality of basic figures constituting the figure set, a second memory for storing, in correlated form, each figure set and an area corresponding to the figure set, a third memory for storing, in correlated form, the basic figures and areas corresponding to the basic figures, and an adding/deleting unit for designating an area corresponding to a figure set or basic figure, thereby to add a basic figure to or delete the basic figure from the first memory. The editing of figure sets, each of which comprises a set of a plurality of basic figures, and particularly the editing of a graphical program, is simplified.
摘要:
An intermediate layer for relieving film fatigue is formed between the conductor and the ferroelectric layer for constituting a ferroelectric device, whereby the film fatigue can be reduced on the surface with respect to the conductor of the ferroelectric layer by this construction.
摘要:
A silver halide photosensitive material after exposure can be efficiently processed in a multi-compartment apparatus comprising a series of processing compartments interconnected through narrow channels to define a continuous processing path, by passing the photosensitive material through the series of compartments along the path. Two or more processing solutions of different compositions are supplied to the path at different positions to fill the compartment with the solutions, while the solution is discharged from the path through an outlet port at an intermediate position. During a quiescent period, the solution is discharged such that the compartment which the photosensitive material first enters and the compartment from which the photosensitive material exits become empty. Operation is restarted by refilling the entrance and exit compartments with fresh solutions.
摘要:
A survivable solar power-generating system for use with spacecraft is disclosed comprising optical means positioned to collect and concentrate solar energy flux, a flexible solar energy flux transmission line for conducting the concentrated solar flux towards a solar energy converter, and solar energy conversion means including an array photovoltaic cells for converting the solar energy flux to electrical power to be applied to on-board equipment of the spacecraft. A protected enclosure is positioned about the photovoltaic cells to shield them from destructive radiation and particulate matter. The transmission line includes a plurality of optical fiber waveguides whose input ends are positioned to receive the concentrated solar energy flux. Means are provided for moving the input ends of the optical fiber waveguides to optimize the quantity of concentrated solar flux entering the waveguides.
