Abstract: A diffracting device consists of a substrate made of LiTaO 3 , an optical waveguide extending in a central upper side of the substrate for transmitting 860 nm wavelength coherent light radiated from a semiconductor laser, a plurality of gratings periodically arranged on the optical waveguide at regular intervals, and a covering layer arranged on the gratings and the optical waveguide. The optical waveguide is formed according to a proton-exchange process. The gratings are made of photoresist material having a refractive index N1=1.5 and a high workability, and the gratings are uniformly formed according to an interference-exposure process. Therefore, the photoresist material is patterned without damaging the optical waveguide with reactive ions. The covering layer is made of Ta 2 O 5  having a refractive index N2=2.0. Therefore, periodic change in the refractive index is generated in a periodic structure of the gratings and the covering layer, and a part of the coherent light is reflected by the periodic structure to fix the wavelength of the coherent light radiated from the semiconductor laser.

Abstract: The vibrator 12 is driven by the output voltage V B  of the power supply 14 using dry batteries or the like at the starting of a paging announcement and is driven by the constant voltage circuit having the output voltage V S  and using the power supply 14 as its power source after the starting. Detecting the paging announcement, the decoder 3 feeds the drive signal C1 to the vibrator controller 11, and the vibrator controller 11 starts the vibrator by the voltage V B  from the power supply 14. When a predetermined time passes from the start, the decoder 3 sends out the control signal C2 to the vibrator controller 11, and switches the drive voltage for the vibrator to the output voltage V S  from the constant voltage circuit 13. When the paging announcement finishes the decoder 3 stops sending out the drive signal C1, and the vibrator controller 11 stops the power supply to the vibrator 12.

Abstract: The circuit processes a colour signal reproduced from a video recorder. The colour signal modulates a carrier with a first carrier frequency. The colour signal modulated to the first carrier frequency is fed to a first mixer (1). This converts the colour signal to a second carrier frequency which is higher than the first. The output signal of the first mixer (1) is fed to a comb filter arrangement (2,3,4). This suppresses cross-talk colour signals from adjacent tracks. The output signal of the comb filter arrangement is fed to a second mixer (5). This converts the filtered signal to a third carrier frequency which is higher than the second carrier frequency. The third carrier frequency pref. corresponds to the colour carrier frequency.

Abstract: An oxygen concentration sensor comprises a sensor element (10) with
a gas-sensing portion (11) formed at a distal end (10a) thereof. The gas-sensing
portion (11) is surrounded by cup-like inner and outer covers (31, 32) that have
bottoms (311, 321) facing the distal end (10a) of the sensor element (10). The
outer cover (32) is provided with a gas hole (23) only at the bottom (321)
thereof. The gas hole (23) introduces the gas inside the outer cover (31). A
flowing direction of the gas is substantially perpendicular to the axial direction

substances flow in parallel with the opening of gas hole (23). As a result, the
amount of the unburned substances deposited in the vicinity of the gas hole
(23) can be reduced greatly. And, the amount of the unburned substances
passing through the gas hole (23) can be reduced greatly.

Abstract: An engine mount comprises a rigid generally cylindrical member
(14) for attachment via an armature (10) to the chassis or body
of a vehicle. A central rigid insert (20) is bolted to the
engine and is supported by a one-piece moulded support (22) made
of resilient material. The resilient support (22) defines a
working chamber (62) which is connected to two interconnected
compensation chambers (42,44) via a restricted-flow conduit
(64,66) for damping transfer of hydraulic fluid and thus damping
vibrations. High frequency vibrations cause a flexible membrane
(60) to vibrate in a space defined between a rigid apertured
plate (58) and an apertured part (56) of the cylindrical element
(14). The apertures (56) expose the membrane (60) to atmospheric
pressure. Abutments (46,50) are mounted within the compensation
chambers (42,44) to limit transverse vibration. The fluid within
the compensation chambers (42,44) and the grooved outer surfaces
of the abutments (46,50), reduce their effect on vertical
vibrations.
