(Problem to be solved)A laser refining apparatus and the laser refining method for efficiently collecting evaporant other than oxygen from an oxidized compound.(Means for solving the problem)The laser refining apparatus comprises a stage inside a processing chamber where an oxidized compound is placed; an irradiation means for irradiating a laser under the condition that the oxidized compound placed on the stage is heated to a temperature at or above the boiling point of said oxidized compound; an attaching medium to which non-oxygen evaporant evaporated by the laser irradiated by the irradiation means attaches; and a feeding means for feeding gas that prevents the non-oxygen evaporant from becoming an oxidized compound into the processing chamber. The attaching medium is positioned so that the non-oxygen evaporant can attach to the attaching medium before becoming an oxidized compound, and the oxidized compound is metal oxide or silicon oxide.

An energy-saving freshwater producing apparatus having a simple apparatus configuration. Seawater is heated by a heat-collecting device based on solar light, and the heated seawater is injected to one or more mist-forming structure formed as a rotor comprising a plurality of collision members formed to extend radially, to form a mist. Water vapor generated from the formed mist is introduced to a heat exchanger arranged in a side-by-side relation to the mist-forming structure in a horizontal direction through a demister, while being carried on an airstream by an airstream-forming device. Low-temperature seawater flows through the heat exchanger vertically from a lower side to an upper side thereof. The introduced water vapor is condensed into freshwater by cold energy of the seawater, and the freshwater is collected.

A semiconductor integrated circuit includes a ring oscillator and a noise canceller. The ring oscillator includes first and second signal generators. The first signal generator is configured to generate a first output signal having a first phase based on an input signal. The second signal generator is configured to generate a second output signal having a second phase different from the first phase based on the input signal. The noise canceller includes first and second amplifiers and an arithmetic module. The first amplifier is configured to amplify the first output signal generated by the first signal generator using a first amplification factor. The second amplifier is configured to amplify the second output signal generated by the second signal generator using a second amplification factor. The arithmetic module is configured to combine the first output signal amplified by the first amplifier with the second output signal amplified by the second amplifier.

In a method for automatically controlling the gear-shifting operation of a vehicle gear transmission so as to shift the transmission to a calculated target position according to the vehicle operation parameter(s), the stability of the calculated target position is discriminated and the required gear-shifting operation is carried out only when the stability satisfies a prescribed condition, whereby unnecessary gear-shifting operations can be effectively eliminated even if for some reason the calculated target gear position frequently changes.

A process for the manufacture of a solenoid operated valve of the double valve seat type ensures that the stroke distance of a ball valve between two valve seats is accurately provided. The ball valve is positioned on a portion of a first valve seat member, and a first jig is mounted on the ball valve. The jig is pressed until an end surface thereof and an abutting surface of the first valve seat member are contacted, thereby forming a first valve seat. The ball valve then is positioned on a portion of the second valve seat member, and a second jig is pressed toward the ball valve until an end surface of the second jig abuts an abutting surface of the second valve seat member, thereby forming a second valve seat. The abutting surfaces of the two valve seat members are abutted, and the two valve seat members are assembled.

A remotely operated, direction switching proportional control valve device comprises a direction switching control valve which includes a hydraulic actuator, an electromagnetic pressure reducing valve interposed between a liquid chamber of the hydraulic actuator and a hydraulic power source and an electromagnetic open or closed valve interposed between the liquid chamber and a liquid tank. Both the pressure reducing valve and the open or closed valve can be operated against an electromagnetic force for return movement. The device eliminates the requirement for a piston stroke detector and may be operated by a single electromagnetic coil.
