摘要： In a predetermined range from a nose portion toward a scroll finish side in a scroll casing of a centrifugal blower, a first clearance dimension on a side of a suction port between an outer periphery of a centrifugal fan and a side plate of the scroll casing is set smaller than a second clearance dimension on a side opposite to the suction port between the outer periphery of the centrifugal fan and the side plate of the scroll casing. In addition, in the vicinity of the nose portion, a first wall part of the scroll casing on the side of the suction port protrudes toward a scroll finish side, from a second wall part of the scroll casing on the side opposite to the suction port.

摘要： A centrifugal multi-blade fan has multiple blades about a rotational shaft and draws in air along the rotational shaft and then blows the air approximately perpendicular to the rotational shaft to reduce wind noise. A scroll casing encloses the multi-blade fan and defines a scroll-shaped airflow passage for directing the air blown from the multi-blade fan. The scroll casing has an intake opening and an outlet opening at a scroll end, in a downstream scroll casing portion. The scroll casing expands such that a flow passage cross-sectional area on the airflow downstream side is larger than that on an airflow upstream side. A ratio of a blade length to a diameter of the multi-blade fan is greater than or equal to 0.12, and an outer scroll casing radius, relative to the rotational axis, increases as a logarithmic spiral, its expansion angle being from 3.3° to 4.8°.

摘要： In a vehicle air conditioner with a heat pump refrigerant cycle, an interior heat exchanger of the refrigerant cycle is disposed in an air conditioning case to heat air in a heating operation and to cool air in a cooling operation. Further, a cooling heat exchanger for cooling air by evaporating the refrigerant is disposed so that a part of refrigerant circulating in the refrigerant cycle flows into the cooling heat exchanger at least in the heating operation. In addition, a decompression unit for decompressing refrigerant flowing to the cooling heat exchanger is disposed, and the decompression unit is opened even in the cooling operation. Accordingly, dehumidifying capacity of the air conditioner can be improved while the refrigerant cycle has a simple structure.

摘要： In a tip portion structure basically having a substrate, a plate spring, and a ground block, the substrate is attached to a signal line on a back surface of the substrate and is contacted on the tip with the signal electrode of the DUT placed on a device stage. The plate spring is made of a resilient material, placed on the front side of the substrate, and positioned to apply a pressure to the substrate. The ground block is positioned between the signal line and the device stage functioned as a ground electrode of the DUT. Alternatively, the tip portion structure further may have a ground plate or a ground surface formed of a conductive thin plate covering entirely the front surface of the substrate, and shaped to surround the signal line in cooperation with the ground block. A plurality of the signal lines may be arranged in parallel on the same plane of the substrate. Another tip portion structure is based on a coaxial cable to be cut from the center at a plane perpendicular to the axial direction thereof along one or more oblique plane. A metal ring fitted over a periphery of the coaxial outer conductor may be used.

摘要： If a refrigerant leaks from an interior heat exchanger, an outside air mode is switched ON, and a first bypass channel is opened to supply air, not having passed through the interior heat exchanger, to a passenger compartment through a defroster opening portion, while also supplying air, having passed through the internal heat exchanger, to the passenger compartment through a foot opening portion. Consequently, air having passed through the first bypass channel and thereby containing a considerable quantity of outside air free from the leaked refrigerant is supplied to the upper side of the passenger compartment, while air having passed through the interior heat exchanger and thereby containing the leaked refrigerant is supplied to the lower side of the passenger compartment, which makes it possible to prevent driver inhalation of the refrigerant.

摘要： A process for manufacturing a high frequency multichip module includes a reception inspection step which includes steps of preparing a vertical-type probe, setting the high frequency bare chip on a device stage, and measuring high frequency characteristics of the high frequency bare chip using the vertical-type probe. The prepared vertical-type probe has a center conductor and ground conductors arranged at both sides of the tip portion of the center conductor in the vertical direction in which the probe is pressed to electrodes of the high frequency bare chip. The high frequency bare chip has a ground electrode disposed at the opposite side of the chip from the signal electrodes on the upper surface of a device stage. Then, only a good product is fed to the next step. After the reception inspection, the process goes to a component mounting step. Preferably, the process goes to the next step when the high frequency multichip modules passes at least on of a performance test and visual inspection after the component mounting step.
