Abstract: An appropriate stereoscopic image of a subject is readily acquired. Provided is a stereoscopic endoscope device including two image capture elements spaced apart from each other and disposed at a distal end of an insertion section to be inserted into a subject; an angle changing mechanism that changes a relative angle between optical axes of the image capture elements; a distance sensor that detects the distance from the image capture elements to the subject; and a controller that controls the angle changing mechanism on the basis of the distance detected by the distance sensor.

Abstract: Provided is a continuous casting method of a silicon ingot for continuously casting the silicon ingot by arranging, inside an induction coil, a bottomless cold crucible having a part along an axial direction that is circumferentially divided into a plurality of strip elements, forming molten silicon inside the cold crucible through electromagnetic induction heating by the induction coil, and solidifying the molten silicon while pulling it down from the cold crucible, wherein as the cold crucible, used is a cold crucible with Ni—B alloy plating on a portion in the inner surface thereof that faces the outer side surface of the molten silicon and the outer surface of the silicon ingot. The method can reduce the damage to the inner surface of the cold crucible, in addition to the contamination of cast ingots with impurities.

Abstract: A warming-up system for vehicle includes: a heat storage device having a heat storage element; a first heat transfer medium circuit for causing a first heat transfer medium to circulate through the heat storage device; and a second heat transfer medium circuit for causing a second heat transfer medium to circulate through the heat storage device. The first and second heat transfer mediums flow into first and second warming-up targets, respectively. The heat storage device includes a first chamber in communication with the first heat transfer medium circuit, a second chamber in which the heat storage element is arranged, and a third chamber in communication with the second heat transfer medium circuit. Heat exchange can be carried out among the first heat transfer medium of the first chamber, the heat storage element of the second chamber and the second heat transfer medium of the third chamber.

Abstract: In an internal combustion engine in which the valve operating characteristic for intake valves can be switched, and the air-fuel ratio can be switched between a relatively lean level and a relatively rich level, the air-fuel ratio is switched in accordance with a change in engine operating condition.

Abstract: Dual video recording/reproducing apparatus includes a video playback unit, a video recording unit having recording circuitry for recording a video output signal from the video playback unit, as well reproducing circuitry for reproducing a video signal, and a sub-picture signal former responsive to a video signal supplied thereto for providing a sub-picture signal adapted to be displayed as a sub-picture insert of a main picture. A switch couples either the video output from the video playback unit or the video output from the reproducing circuitry included in the video recording unit to the sub-picture signal former. The video signal which is not coupled to the sub-picture signal former constitutes the main picture signal; and the sub-picture and main picture signals are combined to form a display signal which, when displayed, produces a main picture and a sub-picture insert.

Abstract: In a multi-function video tape recorder system, a manually operable rotary dial can be used in place of a large number of dedicated manual switches, and so forth to make selections from multiple-choice lists and to assign numerical values for timing, and so forth. The rotary dial is journalled on a fold-down section of the video tape recorder's front console and its manually-actuated rotation is monitored by optical sensors. A microprocessor receives the output of the sensors and so can derive the angular position and speed and direction of rotation of the rotary dial, which may all serve as input parameters. In addition, a ring may be included in the rotary dial assembly, the ring being pivotably slightly relative to the rotary dial itself to provide an addition dimension of information input.
