Abstract: An air-conditioning system for a truck comprises an air-conditioning unit mounted on a vehicle roof, which has an evaporator and other components for constituting a refrigerating cycle to control temperature of air and to supply the conditioned air into a passenger compartment through multiple blower ducts. The vehicle roof is provided with multiple roof openings, through which the air-conditioning unit and the multiple blower ducts are connected. Each of the blower ducts has an air inlet opening at its upstream side and blower openings at its downstream side, and at least two of the air inlet openings are arranged to close to each other so that a bifurcated connecting element connects the two blower ducts to the unit case through one roof opening. Further, multiple blower openings for different operational modes, such as a face blower opening and a nap-taking blower opening, are formed in a common blower duct, to reduce the number of blower ducts and thereby the number of the roof openings.

Abstract: A vehicle air conditioner includes a refrigeration cycle system that includes a compressor for compressing refrigerant, a condenser, a pressure reducing means, and an evaporator, and an air conditioning unit, which operates the refrigeration cycle unit, for air-conditioning air in a passenger compartment. In the air conditioner, the compressor is a motor driven compressor driven by one of a battery that is charged by a generator driven by a vehicle power source and an outside commercial electric power source. The air conditioning unit is an integrated unit of the refrigeration cycle system that includes the motor driven compressor disposed on a vehicle roof.

Abstract: A suction nozzle for applying a suction to an object and thereby holding the object, the suction nozzle including a nozzle portion having an end surface, and a suction passage formed in the nozzle portion and opening in the end surface thereof, the end surface providing a suction surface that applies the suction to the object and thereby holds the object. At least a free end portion of the nozzle portion has a shape whose diameter gradually increases in a direction from the end surface thereof toward a base end thereof opposite to the end surface.

Abstract: A defroster/face cool air passage for introducing cooled air from an evaporator to a defroster opening portion and a face opening portion by bypassing a heater core, and a foot cool air passage for introducing cooled air from the evaporator to a foot opening portion by bypassing a heater core, are formed independently from each other. The foot cool air passage is located at sides of the heater core in a vehicle right-and-left direction. The cooled air from the foot cool air passage is mixed with warmed air having passed through the heater core at an inlet of the foot opening portion. Accordingly, pressure loss at a foot mode in an air conditioning unit with a central installation layout is reduced, and a mounting performance on a central portion of a vehicle instrument panel is improved.

Abstract: An apparatus for supplying, in an electric-component mounting system, electric components to be mounted on a circuit substrate supported by a circuit-substrate supporting device, the apparatus including a support table, and palettes each one of which is detachably attachable to the support table and holds feeders arranged in a reference direction predetermined with respect to the electric-component mounting system, each one of the feeders feeding electric components of one sort, the palettes having different dimensions in the reference direction.

Abstract: Method of mounting an electric component on a component-mounting surface such that the electric component held by a suction nozzle under a negative pressure is forced onto the component-mounting surface, with termination of application of the negative pressure to the suction nozzle, and the suction nozzle is then moved away from the component-mounting surface, the method comprising the steps of: initiating application of a positive pressure to a passage communicating with the suction nozzle, before the electric component is forced onto the component-mounting surface; maintaining the application of the positive pressure to the passage, until the suction nozzle is spaced apart from the electric component by at least 0.4 mm; and then exposing the passage to the atmosphere. Also disclosed is an electric-component mounting system arranged to practice the method.

Abstract: A suction nozzle for applying a suction to an object and thereby holding the object, the suction nozzle including a nozzle portion having an end surface, and a suction passage formed in the nozzle portion and opening in the end surface thereof, the end surface providing a suction surface that applies the suction to the object and thereby holds the object. At least a free end portion of the nozzle portion has a shape whose diameter gradually increases in a direction from the end surface thereof toward a base end thereof opposite to the end surface.

Abstract: An electronic-component supplying system including electronic-component supplying cartridges each of which includes a cartridge frame, an electronic-component holder which holds electronic components and which includes a connection portion connected to a connection portion of the cartridge frame, and an electronic-component feeder which feeds each of the electronic components from the holder to an electronic-component supplying position distant from the connection portion of the cartridge frame, a support member which supports the respective cartridge frames of the supplying cartridges such that the respective electronic-component supplying positions on the cartridge frames are aligned with each other in a predetermined direction, and an engaging device which is provided between the support member and an engageable portion of the holder of each cartridge, the engageable portion of the holder being distant from the connection portion thereof, the engaging device being engageable with the engageable portion of

Abstract: A fuel injection valve has a collar-shaped stopper at the front of a plunger for restricting the plunger stroke between the stopper and the end of a guide pipe. The divergent conical surface or spherical surface is formed at the end of the guide pipe, a spherical surface which makes contact with the conical surface is formed at the opposite side of the stopper of the plunger to the ball, an automatic centering operation is performed at the stroke end of the plunger, thereby preventing the irregular wear of the ball valve and the seat surface to stabilize the performance for a long period of time.

Abstract: In a selective calling circuit including a band-pass filter which may be constituted by an active filter, and a power source for energizing the filter, a control signal is generated which has a predetermined duration in accordance with the output of the band-pass filter at a point of time whereat the output of the band-pass filter reaches a predetermined level. In response to the control signal, there is established a state in which the center frequency of the band-pass filter can be changed, and the output of the power source is changed from a first level to a second level for a period of time substantially corresponding to the predetermined duration of the control signal. At the aforementioned first level, the band-pass filter may be energized, while at the second level, it may be deenergized.
