A closed compressor includes a closed vessel made of steel and a vapor-liquid separator connected to the closed vessel. The closed vessel and the vapor-liquid separator have a discharge steel pipe and a suction steel pipe, respectively, each of which has a hexagonal portion and a threaded portion for connection with an aluminum pipe. The closed compressor of this construction is suited for use in an automotive air conditioner.

A hermetically sealed rotary compressor includes a generally cylindrical sealed vessel having an oil reservoir defined therein for accommodating a quantity of lubricating oil, a drive unit within the sealed vessel, and a compressor mechanism within the sealed vessel. The compressor mechanism includes a cylinder having a compression compartment defined therein and also having upper and lower openings, an eccentric cam provided on a crankshaft for rotation together therewith, and a ring-shaped piston mounted on the crankshaft while encircling the eccentric cam and capable of undergoing a planetary motion in contact with the eccentric cam during rotation of the eccentric cam. The cylinder has a refrigerant intake port defined therein in communication with the compression compartment. A radial vane is slidably accommodated in the cylinder for reciprocating movement in a direction radially of the cylinder and having a radial inner end held in sliding contact with an outer peripheral surface of the ring-shaped piston. An oil supply tube having first and second open ends opposite to each other is disposed with the first open end communicated with the oil reservoir and the second open end communicated with the compression compartment while a generally intermediate portion of the oil supply tube extends outside the sealed vessel.

A closed rotary compressor includes a generally cylindrical sealed vessel having an oil sump defined therein for accommodating a quantity of lubricating oil, a drive unit housed within the sealed vessel and having a drive motor and a shaft driven by the drive motor, and a compressor mechanism housed within the sealed vessel. The compressor mechanism is provided with at least one set of compression elements. This set of compression elements is made up of a cylinder having a compression compartment and a refrigerant intake port both defined therein in communication with each other, first and second bearings secured to the lower and upper end surfaces of the cylinder, respectively, for rotatably supporting the shaft, a crank provided on the shaft for rotation together therewith, a ring-shaped roller encircling the crank and capable of undergoing a planetary motion in contact with the crank during rotation of the crank, and a radial vane slidably accommodated in the cylinder for reciprocating movement in a direction radially of the cylinder. The radial vane has a radial inner end held in sliding contact with an outer peripheral surface of the ring-shaped roller, to thereby divide the compression compartment into a suction chamber and a compression chamber. An oil passage is provided in the compressor mechanism to place the oil sump in communication with the refrigerant intake port. The oil passage has a throttled portion at a location adjacent to the refrigerant intake port.

In a hermetic type compressor, a sliding part (11) between a main shaft (4) and a lower end plate (8) is large in wear, and it is not allowed to operate stably for a long period. By communicating between the sliding part (11) and an oil feed pump (9) through an oil feed port (12), refrigerating machine oil (2) is supplied by force into the sliding part (11), and hence the lubrication is improved and the reliability is enhanced. In particular, it is preferably applied to the hermetic type compressor using HFC derivative refrigerants.

An increase in the number of signal lines of a control apparatus for controlling devices of an automobile can be prevented and safety of the automobile can be secured. An in-vehicle communication system includes an input DHM that obtains device data from an input device, a BCM that generates control data for controlling an output device based on a value of the device data, and an output DHM that controls the output device according to the control data. The input DHM is composed of duplexed input control blocks, duplexed input shared memories, and an input NW control block. The BCM is composed of a BCM_NW control block, duplexed BCM shared memories for different intended uses, and duplexed arithmetic blocks. The output DHM is composed of an output NW control block, duplexed output shared memories, duplexed output control blocks, and a matching circuit.

A single-reflex camera includes a mirror box, and a focus detecting unit. The mirror box further includes a first opening on a side of the image-pickup optical system, which the light flux that has passed the image-pickup optical system enters, and a bottom plate arranged between the mirror and the focus detecting unit, the bottom plate including a plate-shaped front part that extends so as to approach to an optical axis of the image-pickup optical system from the first opening. Part of the condenser lens is located on a side of the optical axis of the image-pickup optical system with respect to a line that is made by extending, parallel to the optical axis of the image-pickup optical system, an end of the first opening on a side of the bottom plate.

A intrusion detection system includes a first sensor device having a first transmission circuit unit that transmits a modulation wave of a first transmission spectrum diffusion signal to a first transmission leakage transfer passage and a second sensor device having a second transmission circuit unit that transmits a modulation wave of a second transmission spectrum diffusion signal to a second transmission leakage transfer passage. The signal interval of the first transmission spectrum diffusion signal is the same as the signal interval of the second transmission spectrum diffusion signal. The first transmission spectrum diffusion signal and the second transmission spectrum diffusion signal are shifted in frequency so that the first transmission spectrum diffusion signal does not overlap with the second transmission spectrum diffusion signal.
