Abstract: The air-conditioner includes a compressor configured to compress and discharge a refrigerant. The air-conditioner includes a condenser configured to cool the refrigerant with air outside of a vehicle compartment. The air-conditioner includes a throttle configured to expand the refrigerant. The air-conditioner includes an evaporator configured to cool air inside of the vehicle compartment to eliminate moisture from the air by the expanded refrigerant. The air-conditioner includes a first refrigerant passage having the condensed refrigerant between the condenser and the throttle. The air-conditioner includes a second refrigerant passage having the evaporated refrigerant between the evaporator and the compressor. The air-conditioner includes a refrigerant pipe located between the first and second passages and configured to exchange heat between the condensed and evaporated refrigerants.

Abstract: An atomization roasting furnace for producing ferrite raw material powder includes an elongated roasting furnace body with a center burner located at the top end thereof. At least three liquid spray nozzles are located in an expansion slope portion below the center burner circumferentially with respect to the center burner. A quencher, located below the elongated roasting furnace body, has a top end connected to a bottom end of the elongated roasting furnace body. Quencher nozzles are located adjacent the top end of the quencher.

Abstract: This invention provides an atomization roasting method which can easily obtain a soft ferrite sintered body, for example, a sintered body having a crystal particle size of not greater than 2 .mu.m, by using as a raw material an ultra-fine powder having a mean particle size of not greater than 0.1 .mu.m obtained by atomization roasting and which can obtain a soft ferrite raw material powder subjected to an oxidation reaction, having an extremely small residual chlorine content, and having and extremely small deviation of high vapor pressure components such as zinc between the atomized raw material solution and the oxide as the product and which can economically produce a soft ferrite core having an excellent power loss characteristic in a high frequency range, particularly in a MHz range, and is extremely effective for reducing the size of a high frequency transformer.

Abstract: A cooler unit housing is located in a passenger room near a dashboard of a motor vehicle. A piping arrangement of the cooler unit comprises a pipe joint which is positioned at and supported by an opening of the dashboard. The pipe joint has a first face facing toward the passenger room and a second face facing toward the engine room. An expansion valve unit is connected to the first face of the pipe joint. Coolant inlet and output pipes are arranged, each having one end connected to an evaporator in the cooler unit housing and the other end led to the expansion valve unit. A grommet is disposed between a peripheral portion of the opening and an outer wall portion of the pipe joint thereby to establish sealing therebetween.

Abstract: In a supercharged engine, a supercharger and a throttle body disposed midway in an intake passage are located away from an engine block. A blow-by gas passage constituting a PCV apparatus is connected between a portion of the intake passage located on the upstream side of a throttle valve and a crankcase. The blow-by gas passage returns the blow-by gas collected in the crankcase to the intake passage. A cooling water passage extending from the engine block is connected to a radiator. A water passage extending from the radiator is connected to the engine block via the throttle body, which water passage encloses the blow-by gas passage in an intermediate portion thereof.

Abstract: A coupler is disclosed which is constructed of metal. The coupler comprises a cylindrical major part having a first cylindrical bore formed therethrough, the cylindrical major part being formed about its cylindrical outer surface with an externally threaded portion and a polygonal enlarged head; and a collar part having a second cylindrical bore formed therethrough, the second cylindrical bore being greater in diameter than the first cylindrical bore. The cylindrical major part and the collar part are coaxially arranged and integrated with each other to constitute a monobloc cylindrical structure. In practical use, the second cylindrical bore can serve as a silencer.

Abstract: In an optical signal generating apparatus of this invention, output light from a light source driven by a light source driver is externally output from an optical receptacle through a variable optical attenuator. An output monitor unit can be detachably connected to the optical receptacle through an optical connector. When an absolute level of the output light is to be set, a CPU compares a set value from an output level setting unit with an output value from the output monitor unit and controls the variable optical attenuator and the light source driver so that a comparison error becomes zero. The CPU maintains the above control of the variable optical adjuster and the light source driver so that the light is output to be the desired level set by the output level setting unit even after the output monitor unit is disconnected from the optical receptacle including the timing at which the comparison error becomes zero.

Abstract: A web feed mechanism for stepwise or continuously feeding a web, such as a printing medium of a printer, or the like, from a roll of web. In the web feed mechanism, slackness, if any, can be absorbed by applying a drag force to the outermost winding of the web roll through a radially inwardly biased sliding member that slides tangentially of the web roll either in the forward direction, in which the web is to be let off from the web roll, or in the backward direction, in which the web is to be taken up onto the web roll. The sliding member is spring biased to slide backward. Upon the web being let off the web roll, the drag slides the sliding member forward, charges its spring and thereby keeps the web under tension. Upon discontinuance of web unwinding, slackness in the web is absorbed by the spring biasing the sliding member to drag the web roll to roll backward.

Abstract: A method for controlling an iron ore pelletizing and pellet processing operation by evaluating the results of the on-stream analysis of the apparent specific gravity or apparent density distributions of the dry and fired pellet samples which permits the operator of the process to determine if any changes in the process control factors are required in order to impart into the fired pellets an apparent specific gravity or apparent density distribution optimized therefor as the fired pellets are used as a blast furnace charge composition. The method includes the use of an apparent specific gravity measuring step wherein a pellet process stream is periodically sampled and the pellet samples are presented in sequence to a weight measurement unit capable of producing an electric signal proportional to the weight of each sample, from which it proceeds into a volume measurement unit photoelectrically responsive thereto to produce an electric signal proportional to the volume of the sample.
