The invention relates to a single-phase induction motor comprising a main winding, an auxiliary winding which is arranged so that an electrical angle of the auxiliary winding is different from that of the main winding, a plurality of driving capacitors which are connected to the auxiliary winding, a relay for controlling on/off of the driving capacitor in response to the driving load, and a rotor having apertures on the gap side of the slots. The invention further relates to a rotor assembling apparatus comprising a bush to which a rotor core assembly is inserted for die-casting, wherein a clearance between said bush and said rotor core assembly is narrower to the extent that said rotor core assembly can be taken out after die casting; and a core band having a clearance between the core band and the bush in the circumferential direction of said bush, said core band is engaged into said bush so that movement in the axis direction is restricted. The present invention can prevent a generation of the electromagnetic noise even during a high-load and high torque operation.

A foldable lighter that prevents inadvertent ignition by erroneously pressing the operating button when folding the swing-arm to make the lighter compact.A foldable lighter 1 that comprises a lighter body 2 that contains a fuel tank, a piezoelectric unit 102, an operating button 8, and a swing-arm 4 connected with free swinging to one end of lighter body 2 and that incorporates a locking mechanism to prevent accidental depression of operating button 8. The locking mechanism consists of a projecting portion 74 formed in a predetermined range of cylindrical walls 26a and 26c made integrally with swing-arm 4 and a hook 8b that extends from the operating button along a portion of the cylindrical walls. The aforementioned predetermined range prescribed for the projecting portions is the range in which the hook 8b interferes with the projecting portions when the swing-arm 4 is turned relative to the lighter body 2 by an angle that is below a predetermined value so that if the operating button 8 is depressed when swing-arm 4 is turned relative to the lighter body 2 by an angle that is below a predetermined value, hook 8b will interfere with projecting portion 74, and depression of the button will be prevented.

A changeover valve (13) connected to a shift valve unit (12) via four oil passages L3-L6, and two pressure regulating valves (14.sub.1, 14.sub.2) are provided. At speed changing when the changeover valve (13) is in a first (right) position, an off-going hydraulic clutch is connected to oil passage L3 to control its pressure drop by the pressure regulating valve (14.sub.1) and an on-coming hydraulic clutch is connected to L5 to control its pressure rise by the pressure regulating valve (14.sub.2). After completion of the speed changing, the changeover valve (13) is switched to a second (left) position. At speed changing when the changeover valve (13) is in the second position, an on-coming hydraulic clutch is connected to L4 to control its pressure rise by the pressure regulating valve (14.sub.1) and an off-going hydraulic clutch is connected to the L6 to control its pressure drop by the pressure regulating valve (14). After completion of the speed changing, the changeover valve (13) is switched to the first position. After completion of the speed changing, oil at line pressure is supplied to the on-coming hydraulic clutch from the line pressure oil passage L2 without passing through the pressure regulating valves, and oil is discharged from the off-going hydraulic clutch without passing through the pressure regulating valves.

A hydraulic control circuit for a hydraulically operated vehicular transmission has at least five forward transmission trains. The hydraulic control circuit is made up of three sets of first through third solenoid valves and three sets of first through third shift valves to be controlled for changeover by the three sets of solenoid valves such that each of the transmission trains is established by changeover combinations of each of the shift valves. The first shift valve controls a condition of communication between an oil supply passage which is in communication with a hydraulic oil pressure source and a first oil passage and a second oil passage which are both on a downstream side of the oil supply passage. The second shift valve controls a condition of communication between the first oil passage and a third oil passage which is on a downstream side of the first oil passage and also controls a condition of communication between the second oil passage and a fourth oil passage and a fifth oil passage which are both on a downstream side of the second oil passage. The third shift valve controls a condition of communication between the fifth oil passage and a sixth oil passage and a seventh oil passage which are both on a downstream side of the fifth oil passage.

An igniter includes an igniter body provided with a liquefied gas reservoir, and a rod-like extension, which extends from the igniter body and has a flame port ejecting gas flame therethrough on its leading end. The base portion of the rod-like extension is supported for rotation with respect to the igniter body so that the angle made between the igniter body and the rod-like extension can be changed to change the direction of the flame port in a free state and locked when the igniting action is to be done.

The invention concerns a reversible rotary compressor which can compress refrigerant in either of the forward and reverse directions, without providing a valve mechanism in a closed container. In a reversible rotary compressor including a cylinder, a rolling piston, and a slide vane, two inlet/outlet ports are formed in a space between the outer surface of the rolling piston and the inner surface of the cylinder in a state that the two inlet/outlet ports are disposed on both sides of the slide vane. The two inlet/outlet ports are closed by the rolling piston when the rolling piston is positioned at the top dead center and fully opened when the rolling piston is positioned at the bottom dead center. Two refrigerant pipes, coupled with the inlet/outlet ports, are provided in the side wall of the cylinder. The two refrigerant pipes are closed by the rolling piston when the rolling piston when the rolling piston is positioned at the top dead center and fully opened when the rolling piston is positioned at the bottom dead center.

An apparatus for controlling an oil pressure for a vehicular automatic transmission has an accumulator connected to an oil passage which is in communication with each of clutches for transmission or speed changing; a regulator valve for regulating an oil pressure to be supplied to the hydraulic clutches; a first pressure control valve of electromagnetic type for controlling an output oil pressure of the regulator valve by causing an oil pressure to act thereupon; and a second pressure control valve of electromagnetic type for controlling a back pressure of the accumulator. A drain port of one of the first and second pressure control valves is connected to an oil passage on an output side of the other of the pressure control valves.
