摘要:
The outlet temperature of a cooler (31) is controlled within predetermined limits in accordance with the difference between a desired set temperature in an enclosure (13) and the actual temperature therein in such a manner as to minimize the time the cooler (31) is energized. Minor temperature variations in the enclosure occuring while the cooler (31) is off are compensated for by positioning an air mix door (37).

A mold powder for use in continuous casting, containing specified amounts of CaO, Al.sub.2 O.sub.3, TiO.sub.2, Li.sub.2 O, BaO, MgO, F and Na.sub.2 O, and further containing at least one of BN and C as aggregate. The mold powder, when used in continuous casting of a steel rich in strong reducing metal elements such as Al, Ti, REM and so forth, remarkably suppresses generation of deterioration in the surface quality of the slab and break out of the slab which are attributable inferior lubrication.

In a method of manufacturing a compact and light-weight chip-type aluminum electrolytic capacitor, thin external leads are welded to flat anode and cathode foils. The anode and cathode foils are superposed with an insulating spacer interposed therebetween. The portion between the anode and cathode foils is impregnated with an electrolytic solution to obtain a capacitor element. The two surfaces of the capacitor element are covered with synthetic resin laminate films. The openings of the laminate films are welded and sealed to complete the capacitor.
摘要:
A sensor (24) is provided to sense the humidity at the inner surface of a window of a vehicle interior. When the sensed surface humidity is above a certain value, the possibility of the window being fogged arises and a humidifier (28) is de-energized. The humidifier (28) is normally operated to increase the interior humidity to within a desirable range. When the surface humidity is above a higher value, the air interior air control system is operated to reduce the interior humidity by turning on a defroster or the like in accordance with the outside air temperature.

A pollution control element-retaining or -mounting member (2) for mounting a pollution control element (1) within a casing and that shows good canning operability, that is not separated from the pollution control element during the canning operation, and that is excellent in one, some or all of heat resistance, an aerial pressure retaining property and erosion resistance. The pollution control element-mounting member (1) comprises a mat (2) containing fiber material, with the mat having a thickness with an external portion (2a) having an external peripheral surface for contacting the casing (4) and an internal portion (2b) having an internal peripheral surface for contacting the pollution control element (1). At least the internal peripheral surface of the internal portion, and optionally the external peripheral surface of the external portion, (2a) is impregnated with a friction/adhesion controlling agent (3) such that the coefficient of friction between the external peripheral surface and the casing (4) is lower than the coefficient of friction between the internal peripheral surface and the pollution control element (1). The friction/adhesion controlling agent (3) can decompose and dissipate under operating conditions of the pollution control element (1).
摘要:
A particle board having wooden materials coated with an adhesive of a thermosetting resin and pressurized with being heated includes a core layer and face layers provided on both, front and back, sides of the core layer. The wooden materials of the face layer are smaller in the average particle diameter than the wooden material of the core layer and voids between the adjacent wooden materials in the face layer and the core layer are filled with resin particles of a thermoplastic resin by being pressurized with being heated.
摘要:
The inventive optical module has a feeder line for electrically connecting a semiconductor laser with an electric signal input/output unit of a package. The feeder line has a dielectric substrate and a conductor film formed on the dielectric substrate, which consists of a material having thermal conductivity smaller than that of aluminum oxide. Thus obtained is an optical module capable of inhibiting a semiconductor laser from wavelength change caused by heat flowing into the same in a high-density wavelength division multiplex optical transmission system multiplexing a plurality of signals in an optical wavelength region in high density and transmitting the same.
摘要:
A proportion of outside air to recirculated air is reduced when a sensed humidity in a vehicle compartment (14) drops below a first predetermined value. If the humidity is still below the first predetermined value after a certain amount of time has elapsed, a humidifier (24) is turned on. Conversely, if the humidity rises above a second predetermined value which is higher than the first predetermined value, the humidifier (24) is turned off. If the humidity is still above the second predetermined value after a certain length of time has elapsed, the proportion of outside air to recirculated air is increased.
