摘要： In an optical signal reproducing apparatus for a conventional disc phonograph record, the groove of said record is irradiated with the light beam from a direction that varies cyclically at a constant frequency in a plane. Said plane includes both the tangential velocity vector of the groove and a normal line to the surface of the groove. At the moment that the light beam irradiates the surface of the groove from a perpendicular direction, the reflected light beam traces back the same path as that of the irradiating light beam. When a photo-detector is limited by a slit to detect only the reflected light beam tracing back the same path as the irradiating light beam, the photo-detector detects light pulses which are pulse-phase-modulated by the slope angle of the surface of the groove. The recorded signal can be reproduced by demodulating said pulse-phase-modulated pulses.

摘要： An engine is provided with primary and secondary turbochargers. In a small intake air mass range, only the primary turbocharger is caused to operate, and in a large intake air mass range, both the primary and secondary turbochargers are caused to operate. A waste gate valve and an exhaust bypass valve are controlled so that the supercharging pressure approximates to a target supercharging pressure. The target supercharging pressure in the large intake air mass range is set lower than that in the small intake air mass range.

摘要： A turbo-supercharger for an engine includes a turbine casing formed with two scrolls. A shut-off valve is provided for closing one of the scrolls in a low speed engine operation. The shut-off valve is operated by a pneumatic actuator which is normally biased to force the shut-off valve to the open position. Under a low speed engine operation, the intake suction pressure is applied to the actuator to move the shut-off valve to the closed position.
