An air-outlet mode selecting device includes first and second rotary doors. Each of the first and second rotary doors has rotary shafts separated from each other in an axial direction of the rotary shafts, an outer peripheral door surface that is provided at a position separated radial outward from the center line of the rotary shafts and is turned with the rotary shafts, and left and right side plates for connecting both ends in the axial direction of the outer peripheral surface and the rotary shafts. One of the first and second rotary doors opens and closes a specified opening among three openings and other rotary door opens and closes the remaining two openings among the three openings. Accordingly, door operation force and air flow resistance can be effectively reduced, and the size of the air-outlet mode selecting device can be effectively reduced.

A speaker system includes a cabinet, a front baffle, a speaker unit, a rear baffle, and a fitting member fitted in the rear baffle. The front baffle includes a front duct segment extending backward from the rear thereof. The rear baffle includes an opening portion, a duct connecting portion, and a receiving portion having a semicircular cross section. The receiving portion extends from the opening portion to the duct connecting portion while protruding backward. The opening portion, the receiving portion, and the duct connecting portion have a groove. The receiving portion has an engagement hole. The fitting member having a semicircular cross section is formed by double molding. The frame of the member is made of relatively rigid resin and the rim thereof is made of relatively flexible resin. The frame has an engagement projection. The receiving portion and the fitting member constitute a sealed rear duct segment.

When an electrode component is inserted into a through hole from one side and then rotated, parts of a conductive film are cut by a cutting blade. Another electrode component including a chip component whose one terminal is connected to an electrode of this electrode component is inserted into the through hole from the other side. When compression bonding is applied to the both electrode components so as to be joined together, an electrode of the former electrode component and the electrode of the latter electrode component are spread within the through hole with the pressure. The spread electrode of the former electrode component contacts a portion of the conductive film that is electrically connected to a front surface wiring, and the spread electrode of the latter electrode component contacts another portion of the conductive film that is electrically connected to a back surface wiring.

An apparatus for supplying a semiconductor process gas charged in a large-capacity gas vessel to a plant where the gas is used, after reduction of the pressure of the gas. The gas cylinder 21 is composed essentially of a cylindrical portion 22 and hemispherical portions 23 and 24 formed at the ends of the cylindrical portion respectively. The gas cylinder 21 has a gas charge port 26 at one hemispherical portion and a gas discharge port 27 at the other hemispherical portion both of which opening in alignment with the axis 25 of the cylindrical portion 22. A charge valve 28 and a gas discharge unit 29 having at least a gas vessel valve 30 and a pressure reducing valve 32 are connected to the gas charge port and the gas discharge port respectively. The gas cylinder 21 is housed together with the charge valve 28 and the gas discharge unit 29 in a container 36.

A centrifugal-type blower includes a shaft, a fan, and a casing. The casing includes an inlet, an air passage, and a side wall part. A first distance from a center of the fan to the wall part at an inlet side end portion in a radial direction of the fan gradually increases from a volute start part to a volute end part. A second distance from the center to the wall part at any position thereof from an intermediate position to a counter-inlet side end portion in the radial direction is larger than the first distance within a first range. The second distance gradually decreases from the volute start part to a predetermined position. The second distance has the same length as the first distance within a second range.

The blowing opening portions 20, 21, 22 and the communicating passage opening portion 27 are opened and closed by the first 25 and the second rotary door 26, the fork-shaped spring 41 is arranged close to an intermediate position between the door rotary shafts 25b, 26b, a spring force of one arm portion 41b of the fork-shaped spring 41 acts on the first rotary door 25 so that a load caused by the door self-weight can be canceled, and a spring force of the other arm portion 41c of the fork-shaped spring 41 acts on the second rotary door 26 so that a load caused by the door self-weight can be canceled. Due to the above structure, an increase in the door operating force caused by an influence of the door self-weight can be suppressed by a very simple structure.

An air passage switching device for a vehicle air conditioner includes first and second openings and a rotary door for opening and closing the first and second openings. A rib having a first middle seal surface and a rib having a second middle seal surface are provided in a case to protrude an inner side and to be separated by a predetermined angle in a rotation direction of the rotary door. Further, the rotary door has a door structure angle that is larger than a door operating angle. In addition, the first and second middle seal surfaces and first and second end seal surfaces are provided in the case so that the predetermined angle is a difference between the door structure angle and the door operating angle. Accordingly, arrangement positions of the first and second openings can be readily set without increasing a door operating amount.
