摘要:
A swash plate type compressor is disclosed which is intended to prevent a hemispherical shoe, provided between the piston and the swash plate, from being spun on slat surface of the swash plate during operation of the compressor. In the preferred embodiment of the invention, the swash plate is formed with a step and the shoe with a cut portion engageable with the step so that the shoe is prevented from being spun on the slant surface of the swash plate which provides a turning moment to the shoe. The step is formed by an annular projection having an annular wall portion defining the inner limit of the slant surface area of the swash plate with which the flat face of the hemispherical shoe is kept in sliding contact, and the cut portion of the shoe has a curved surface conforming to the curvature of the annular wall portion. The shoe is located with its cut portion slidably contactable with the annular wall portion.

A swash plate type compressor is provided with a plurality of cylinders and a front and rear cylinder blocks having a crank case connected to a suction port. The cylinder blocks are connected to a front and rear housing sections in order to cover the cylinders. Each housing section contains a discharge chamber. A drive shaft is rotatable supported by the cylinder blocks. One end of the drive shaft is sealed within the front housing. A swash plate is mounted on the drive shaft and is rotatably disposed within the crank case. A plurality of two-head pistons engage the swash plate via a pair of shoes. The pistons move within their respective cylinders in cooperation with the swash plate. The refrigerant is sucked into each cylinder via a suction passage, and is then compressed therein. The refrigerant is discharged into the external refrigerating circuit through the front and rear discharge chambers, .and the front and rear discharge ports. A discharge passage is provided within the drive shaft, and interconnects the front and rear discharge chambers. A valve is provided at one end of the discharge passage to control the opening of the discharge port in relation to the pressure difference between the front and rear discharge chambers.

A drive control system for an electric vehicle and a method of drive control of the electric vehicle. The drive control system for the electric vehicle includes a drive motor target torque calculation processing device for calculating a drive motor target torque representing a target torque of a drive motor; and a drive motor target torque restriction processing device that judges whether or not a parking mechanism is in operation and, if the parking mechanism is in operation, restricts variations in the drive motor target torque.

Small-sized pressure vessels made of sheet metal which are suitable for the storage and carriage of pressurized liquid, pressurized gas and the like are provided herein, and also the method of manufacturing these pressure vessels which comprises in combination a process in which two cup-shaped pieces made of sheet metal are fitted, or a jointing ring made of metal or synthetic resin is fitted to the open end of one of both cup-shaped pieces along its inner or outer circumferential surface, and hot-melting type adhesives are applied to the jointing surface of each cup-shaped piece to which the jointing ring is attached and the jointing ring itself or the open end of the other cup-shaped piece. Also both cup-shaped pieces may be butted or fitted in their open ends in which, for example, one cup-shaped piece which has the jointing ring fitted thereto and the other cup-shaped piece are heated to 120.degree. C.-250.degree. C. to melt the adhesives and are then cooled to solidify the adhesives.

During a standstill, a prescribed rotation speed N3, which is lower than a prescribed rotation speed N2 used during a travel at a low vehicle speed, is set as a minimum rotation speed Nemin (S410), and when a demand for an idle operation has been made (S490), the minimum rotation speed Nemin is set as a target rotation speed Ne* and the value 0 is set as a target torque Te* (S500), whereby an engine is controlled. As a result of this, it is possible to improve the fuel consumption of a vehicle when the engine is operated at idle at standstill compared to a case where the engine is operated at idle at the minimum rotation speed Nemin for which the prescribed rotation speed N2 is set regardless of whether or not the vehicle is at a standstill.

There is obtained a lubricating oil having good solubility with both HFC refrigerant and contaminants by adding PAG having a viscosity of not more than 70 cSt (40° C.) to a synthetic lubricating oil, such as polyvinyl ether and ester oils at an amount of not less than 0.1 wt % and not more than 20 wt % (desirably, not less than 20 wt % and not more than 10 wt %). Therefore, in a refrigerating/air-conditioning machine equipped with a compressor using this present lubricating oil together with a HFC refrigerant as a working fluid, deflection in the ratio of the mixture within the machines is not caused and, consequently, the efficiency for washing capillary tubes is not reduced. In that case, a high-reliable refrigerating/air-conditioning machine can be obtained at a low price without any modification of the refrigerating/air-conditioning machine.

To form a gel bed in a cylindrical column for liquid chromatography, a gel bed section is provided between upper and lower liquid-tight partition members, positioned apart from each other at upper and lower positions in the column. Liquid is continuously percolated downward through the gel bed section to form a gel bed in the gel bed section and a liquid pressure is applied onto the upper partition to move the partition member downward following a downward movement of the upper surface of the gel bed.

A game software service system is connected to a monitor to display an image for game. A CPU and a PPU which cooperates with the CPU are accommodated within a housing. A plurality of storage mediums which respectively store game programs are attached to the housing in an attachable/detachable manner. The respective storage mediums are commonly connected to an address bus and a data bus of the CPU and the PPU, and assigned with a common address space. A first controller is used for playing a game. Any one of the storage mediums is selected by operation of a second controller. When a menu showing a plurality of game names is displayed on the monitor, accesses from the CPU and the PPU to a selected storage medium are enabled in response to the operation of the second controller. The CPU and the PPU execute a program of the selected storage medium to display the image for game on the monitor. In that state, when the first controller is operated, displaying condition on the monitor screen is responsibly changed by the CPU and the PPU.
