摘要:
A control valve is used for a variable displacement compressor installed in a refrigerant circuit of a vehicle air conditioner. The control valve has a valve housing. A valve chamber is defined in the valve housing. A valve body is accommodated in the valve chamber. A pressure sensing chamber is defined in the valve housing. A pressure sensing member separates the pressure sensing chamber into a first pressure chamber and a second pressure chamber. The pressure at a first location in the refrigerant circuit is applied to the first pressure chamber. The pressure at a second location in the refrigerant circuit, which is downstream of the first location, is applied to the second pressure chamber. The pressure sensing member moves the valve body in accordance with the pressure difference between the first pressure chamber and the second pressure chamber such that the displacement of the compressor is varied to counter changes of the pressure difference. At least one of the first pressure chamber and the second pressure chamber forms a part of the refrigerant circuit.

A temperature sensing unit produces an output signal commensurate with temperature, the output signal serving as a basis for discriminating a temperature above a predetermined threshold temperature as well as a rising temperature gradient over a predetermined period of time. When means for effecting the discrimination operation senses both conditions, a temperature measuring unit begins measuring temperature on the basis of an input from the temperature sensing unit. When said measurement begins, the measuring unit raises the resolution of temperature information from the sensing unit.

Provided is a novel lithium silicate-based material useful as a positive electrode material for lithium ion secondary battery.The lithium silicate-based compound is represented by Li1.5FeSiO4.25. The lithium silicate-based compound is a compound including: lithium (Li); iron (Fe); silicon (Si); and oxygen (O), and expressed by a composition formula, Li1+2δFeSiO4+δ−c (−0.25≦δ≦0.25, 0≦c≦0.5). The lithium silicate-based compound, of which iron (Fe) is trivalent, exerts a remarkable chemical stability as compared to Li2FeSiO4.

The check valve includes a valve housing, a valve body and an urging member. The valve housing has a peripheral wall and a valve seat. The peripheral wall has an opening therethrough for fluid communication. The opening is located more downstream than the valve seat. The end of the opening on the side of the valve seat is spaced at a predetermined length in a direction in which the valve body is spaced away from the valve seat. A first throttle is formed in a space between an inner peripheral surface of the valve housing and an outer peripheral surface of the valve body until the valve body is slid in the direction for the predetermined length from the state in which the valve body is seated on the valve seat.

An aluminum based composite material includes a matrix and a reinforcing material. The matrix mainly contains aluminum and contains magnesium. The reinforcing material is constituted of whisker and nitriding short fiber which is treated by nitriding process. The reinforcing material is dispersedly contained in the matrix. The aluminum based composite material has a high thermal resistance.

A compressor has a housing and a cylinder block. The housing includes suction and discharge chambers. The cylinder block is fixed to the housing via a valve plate assembly. The valve plate assembly forms suction and discharge ports and suction and discharge valves. A partition wall is formed with the housing, and separates the suction chamber and the discharge chamber. The housing includes a first surface, and the cylinder block includes a second surface. At least one of the first and second surfaces is concave in shape. The cylinder block is screwed to the housing at the partition wall or a position closer to the central axis of the housing than the partition wall by a bolt so that the first surface faces the second surface.

The deformation of cylinder bores in a cylinder block is prevented. The cylinder block 19 is inserted into a front housing 11. The cylinder block 19 is fixed to the front housing 11 by tightening plural screws 38 which penetrate through the cylinder block 19, from an end surface 191 side thereof, to be screwed into an end wall 32 of the front housing 11. Plural deformation absorbing grooves 39 are provided on the end surface 191. Each one of the deformation absorbing grooves 39 is provided in each intermediate space between the adjacent paired cylinder bores 41.

A gasket 36 is interposed between an end face 341 of a front housing 11 and an end face 351 of a rear housing 12. A coned disc spring 37 is interposed between an end face 192 of a cylinder 19 and the end face 341 of the front housing 11. When the end faces 341, 351 are caused to approach each other so as to be joined together, the coned disc spring 37 is first held by the end face 341 of the front housing 11 and the end face 192 of the cylinder 19. When the end faces 341, 351 are caused to approach each other further so as to be joined together, the gasket 36 is held between the end faces 341, 351. Thus, it is ensured that the cylinder and the seal material interposed between the first housing and the second housing are held therebetween.
摘要:
A laser recording apparatus for recording a continuous tone image on a photosensitive material by scanning the material with an analog light beam which was intensity-modulated on the basis of an image signal is disclosed. The apparatus uses a semiconductor laser as a light beam source, and the emission light level of the semiconductor laser is controlled according to an image signal by making use of the charging and discharging of a capacitor and without making use of the well-known APC circuit. Thus, the apparatus is free from the problem of circuit oscillation that arises when using an APC circuit and permits a repeatedly increasing and decreasing emission light level instruction signal to be followed by the semiconductor emission light level accurately and with a satisfactory response speed, so that it is possible to record a continuous tone image at a high speed and with high accuracy.
