A rotary connector 1 has a fixed case 3 for being mounted on a base 5 for a switch 4. The fixed case 3 has a first screw insertion hole 3a formed open therein for insertion of a screw 6. The screw 6 has a flange 6a. The fixed case 3 or the base 5 has a resilient pawl 3f formed therein for engagement with the flange 6a. With such structure, it is possible to screw-fix both the rotary connector and the base onto the steering column. The screw is securely kept in the rotary connector during transport and assembly by the resilient pawl.

A headup display including a light emission-type display source, a concave mirror having an spherical reflecting surface and located so as to reflect light emitted from the display source, and a reflection-type hologram located so as to reflect the light reflected on the concave mirror toward an observer in a mobile unit. The concave mirror is configured so that its lateral focal length contributing to lateral enlargement of a displayed image is shorter than its longitudinal focal length contributing to longitudinal enlargement of the displayed image. The reflection-type hologram is configured so that its longitudinal focal length contributing to longitudinal enlargement of the displayed image is shorter than its lateral focal length contributing to lateral enlargement of the displayed image.

This invention provides a rotary connector in which flexibility is imparted against the stress applied in the transverse direction of an elastic tongue by partially reducing rigidity of the elastic tongue plate in its transverse direction. Therefore, even if the elastic tongue or the flexible cable accidentally comes into contact with the inner wall of the housings due to a deviation from the tolerance of assembly, they do not come into strong contact. The rotor housing is rotatably fitted to the stator housing. The flexible cable 3 is spirally accommodated in the space defined by both housings. The terminal 4 is electrically connected to the conductor cable 31 exposed from the flexible cable 3. The support 5A resin-molds the terminal 4 and is fixed to at least one of the stator housing and the rotor housing. The elastic tongue 8 is fixed to the support 5A and is so disposed as to extend along the flexible cable 3. The width W1 of the elastic tongue 8 on the fitting side to the support 5A is relatively reduced to a smaller width than the width W2 on the opposed side so as to partially reduce rigidity in the transverse direction.

An absolute encoder device comprises a code plate having a 1-track type absolute pattern whose minimum reading unit length is .lambda., a first incremental pattern with a pitch .lambda., and a second incremental pattern with pitch 2.sup.-n .lambda.. The device also comprises a detector section, which is movable relative to the code plate, which includes a detector detecting the absolute pattern and obtaining an absolute pattern signal, a detector detecting a first incremental pattern and obtaining a first incremental signal, and a detector detecting a second incremental pattern and obtaining a second incremental pattern signal. A shorter cyclic incremental signal is generated from the first incremental signal by interpolating and the shorter cyclic signal is synchronized with the second incremental signal. The absolute pattern signal, the second incremental signal and the synchronized first incremental signal represent the relative positional relationship between the code plate and the detector section.

摘要:
Plasma processing of plural substrates is performed in a plasma processing apparatus, which is provided with a plasma processing chamber having an antenna electrode and a lower electrode for placing and retaining the plural substrates in turn within the plasma processing chamber, a gas feeder for feeding processing gas into the processing chamber, a vacuum pump for discharging gas from the processing chamber via a vacuum valve, and a solenoid coil for forming a magnetic field within the processing chamber. At least one of the plural substrates is placed on the lower electrode, and the processing gas is fed into the processing chamber. RF power is fed to the antenna electrode via a matching network to produce a plasma within the processing chamber in which a magnetic field has been formed by the solenoid coil. This placing of at least one substrate and this feeding of the processing gas are then repeated until the plasma processing of all of the plural substrates is completed. An end of seasoning is determined when a parameter including an internal pressure of the processing chamber has become stable to a steady value with plasma processing time.
