摘要： An electronic timepiece has a wheel train mounted for undergoing rotation and a transmission wheel for undergoing rotation in accordance with rotation of the wheel train. A contact point spring is connected to the transmission wheel for rotation therewith. The contact point spring extends substantially linearly through a rotational center of the transmission wheel. First and second detection patterns contact the contact point spring during rotation of the transmission wheel to generate a rotational position detecting signal corresponding to a rotational position of the transmission wheel. The first and second detection patterns are disposed at an angle of substantially 180 degree relative to the rotational center of the transmission wheel.

摘要： This invention provides a method for the prevention of oxidation of resulting methacrolein immediately after its discharge from a reaction tube upon production of the methacrolein by vapor-phase oxidation of isobutylene, tertiary butanol or methallyl alcohol with a molecular-oxygen-containing gas in the presence of a catalyst. An inert gas and/or recirculated reaction gas or a mixed gas of an inert gas and/or recirculated reaction gas and air is fed and mixed with a reaction product gas immediately after an outlet of the reaction tube.

摘要： A water jet discharge pipe which produces a wide effective spray area and long water reach at low pressure and water volume. Compressed air is injected around the periphery of the pressurized water stream produced through an inner cylindrical member and which is throttled by a nozzle extending into such inner cylindrical member. The injected air prevents reduction of the flow velocity of the water by contact with the inner wall of the cylindrical member. In addition, external air is introduced through air inlets in an outer cylindrical member extending from the inner cylindrical member so as to straighten the air layer accompanying the water jet exiting from the inner cylindrical member and suppress premature dispersal of the water stream prior to ejection from the outer cylindrical member. After such ejection, expansion of the injected air atomizes the water stream to provide large area coverage thereof.
