摘要:
The present invention provides a precoated metal sheet for light reflectors having a high diffuse reflectance of visible lights and an excellent heat absorptivity, and also provides the electric or electronic apparatus using it. The precoated metal sheet comprises a metal sheet or plated metal sheet, a visible light reflective coat on one surface of the sheet, and a heat absorptive coat on the other surface of the sheet. The visible light reflective coat has a diffuse reflectance of visible rays of not less than 0.7 in a wavelength of 400 to 700 nanometers. The heat absorptive coat has a total emissivity of infrared rays of not less than 0.7 in the range of wave number of 600 to 3000 cm−1 measured at a certain temperature within the range of from 80 to 200 degrees centigrade.

A gasket (10) used in a compressor in which a gas is force-fed, improve the sealability and contribute stored miniaturization of the compressor. The gasket (10) includes a raised portion (35) rising so as to surround a sealed portion. An end (43) of the raised portion (37) and a base surface (30) of the gasket (10) are not positioned on a single plane. In addition, the raised portion (35) is constituted with a flat surface (40) set at a height different from the height of the base surface (30) and an inclined surface (41) with a predetermined angle of inclination connecting the flat surface (40) with the base surface (30).

The present invention provides an ultrasonic diagnostic apparatus. The ultrasonic diagnostic apparatus comprises an ultrasonic probe (1) for transmitting ultrasonic pulses into a living body and receiving ultrasonic reflected waves from the living body, a phase-detecting section (5) for detecting each phase of the ultrasonic reflected waves, and a phase-difference detecting section (6) for determining a phase difference in the repetition period of the ultrasonic transmitting/receiving operation according to the detected phase signals. The ultrasonic diagnostic apparatus further includes a data analyzing section (7) for calculating the movement velocity of the living body tissue and the blood flow velocity according to the phase difference of the ultrasonic reflected waves and tracking the movements of the living body tissue and the blood according to the movement values calculated by the velocities, and a display section (13) for displaying the tracked results and the movement value and velocity waveform of the living body tissue and the blood simultaneously through a display control section (10).
摘要:
In a control system of an internal combustion engine including an intake flow control valve disposed downstream of a throttle valve, a controller controls opening and closing of the intake flow control valve, depending upon an operating state of the internal combustion engine. Upon detection of a failure in the intake flow control valve, the controller controls an intake air amount or flow rate to a different value.

Preferably, the soluble lubricating resin film mainly comprises (A) an alkali-soluble polyurethane resin composition containing a carboxyl group or a sulfonic acid group within the molecule and having a glass transition point of 100° C. or more as a dry film and (B) a lubricating function-imparting agent in an amount of from 1 to 30% by mass based on the polyurethane composition.
摘要:
An expansion device capable of preventing an abnormal increase in the high-pressure in a freezing cycle and having, as an integrated unit thereof, a mechanism capable of quickly responding to an abnormal increase in the high-pressure and the low-pressure is provided. A means for displacement (bellows) 28 which becomes displaced in correspondence to the high-pressure is linked to a valve element 24 of a restrictor valve mechanism 32 to displace a rod 34 provided with a safety valve mechanism 33. If the high-pressure reaches a level equal to or higher than a first specific pressure (the limit to the normal operating pressure), a first portion 26 of the safety valve mechanism 33 becomes disengaged from a relief hole 27 that communicates between a high-pressure space 29 and a low-pressure passage 31 to be replaced by a second portion 25 which allows passage through the relief hole 27, thereby leaking the coolant in the high-pressure space 29 to the low-pressure passage 31 and preventing a further increase in the high-pressure. In addition, a low-pressure side rupture disk mechanism 40 that becomes ruptured if the low-pressure reaches a level equal to a second specific pressure to communicate between the low-pressure passage 31 and the atmosphere is provided at the low-pressure passage 31. A high-pressure side rupture disk mechanism 50 that becomes ruptured if the high-pressure reaches a level equal to or higher than a third specific pressure to communicate between the high-pressure passage 30 and the atmosphere is provided at the high-pressure passage 30.
摘要:
A refrigerant compressor is provided. A cylinder block has a plurality of cylinder bores axially formed therethrough. A plurality of pistons are slidably received in the cylinder bores, respectively. A housing is secured to the cylinder block and has a crankcase defined therein. A drive shaft extends through the crankcase and has one end on a cylinder block side. A torque-transmitting member is received within the crankcase and mounted on the drive shaft, for rotation in unison with the drive shaft for converting torque transmitted from the drive shaft into reciprocating motion of each of the pistons. A bearing supports the one end of the drive shaft. The cylinder block has a bearing-receiving chamber having the bearing received therein, a lubricant-collecting groove formed at a rim of a crankcase-side opening of each of at least one of the cylinder bores in a manner such that the lubricant-collecting groove is open to the crankcase, for collecting lubricant therein, and a lubricant supply passage connecting between the lubricant-collecting groove and the bearing-receiving chamber to thereby supply the lubricant collected in the lubricant-collecting groove to the crankcase. The lubricant collected at a bottom of the crankcase is drawn up by rotation of the torque-transmitting member and splashed within the crankcase.

The present invention provides an inexpensive, non-chromium anticorrosive coating composition and anticorrosion treatment method, which are superior in anticorrosion to conventional chromium-containing anticorrosive compositions.The anticorrosive coating composition of the invention comprises 0.2 to 50 g of thiocarbonyl group-containing compound, 0.1 to 5 g of phosphate ions, and aqueous resins in water. The amount of the thiocarbonyl group-containing compound and phosphate ions is based on one liter of the total amount of the aqueous resin and water. The above anticorrosive coating composition can further comprise 10 to 500 g of water-dispersible silica. The anticorrosion treatment method of the invention comprises coating zinc-type coated steel or non-coated steel with the anticorrosive coating composition.
摘要:
An air-fuel ratio control device for an internal combustion engine of a vehicle is disclosed. The device controls the air-fuel ratio with a target value which is larger than the stoichiometric air-fuel ratio, as a control center, in an idle condition. The target value is changed to become small when an amount of intake air in an idle condition is larger than a predetermined value.
