Abstract: An oscillation circuit section is provided which can attain the reduction of a consumed power amount and the reduction of a manufacturing cost. In a semiconductor device, voltages are generated to drive the oscillation circuit section by using a plurality of MOS transistors which are connected in serial and each of which is in a diode connection. At this time, each voltage is generated based on a power supply voltage and a ratio of the threshold voltages of the plurality of MOS transistors. Therefore, it is possible to suppress the threshold voltage of each MOS transistor, to save an area of each MOS transistor, and to reduce the consumed power amount of the oscillation circuit section.

Abstract: A method of operating ozone production facilities comprises supplying a starting gas from oxygen production facilities alone to an ozonizer when the consumption of oxygen is within the production capacity of the oxygen production facilities; or mixing pure oxygen gas from liquid oxygen facilities with the gas from the oxygen production facilities, and supplying the resulting mixed gas as the starting gas to the ozonizer, when the consumption of oxygen exceeds the production capacity of the oxygen production facilities. Thus, the ozone production facilities, even if small in scale, can always supply an ozone-containing gas having an arbitrary ozone concentration, ranging from the maximum to a lower concentration.

Abstract: Ozone production facilities comprising oxygen production facilities as a starting gas supply source, an ozonizer, and an ozone analyzer, and adapted to supply the starting gas by the oxygen production facilities, ozonize the starting gas by the ozonizer to produce an ozone-containing gas; the ozone production facilities further including liquid oxygen facilities as another starting gas supply source, and an oxygen flowmeter for monitoring the flow rate of oxygen supplied by the liquid oxygen facilities.

Abstract: An illuminating optical system for use in a microfilm reader/printer or the like for illuminating a film comprises an axially symmetric lens system and an anamorphic lens system. The anamorphic lens system includes a condenser lens opposed to a light source. A microfilm reader/printer having such an illuminating optical system causes the axially symmetric lens system to illuminate the microfilm during a reading operation, and the anamorphic lens system to illuminate the film during a printing operation.

Abstract: A wire harness and a method of and apparatus for manufacturing the same is disclosed. The present wire harness comprises a plurality of electric wires, constituting its trunk line portion and branch line portions, laid on a wiring board so as to form a desired pattern and a clamp chain, formed of a plurality of wire clamps arranged in parallel at predetermined pitches, attached to the edge portion at least at one side of the wiring board, in which the electric wires are locked to specific wire clamps of the clamp chain, and thereby, both end portions of the electric wires are arranged so as to be in parallel at predetermined pitches and projecting from the edge portion.

Abstract: Described herein is a method and an apparatus which permit terminal-carrying ends of wire units to be automatically inserted into a connector housing in a reliable manner almost irrespective of the type and size of the terminal elements to be inserted. This is attained by providing a transfer plate which is movable to a position confronting a selected one of a plurality of connector housings set on an assembling table. An assembling head is mounted on the transfer plate movably in vertical directions and also in directions toward and away from the transfer plate. A wire-embracing terminal portion and a wire portion of the wire unit are gripped by means of openable and closable paired terminal gripping pawls and wire gripping pawls which are vertically movably supported on the assembling head. The posture of the terminal element is adjusted by lowering a terminal presser plate which is vertically movably provided between the paired terminal gripping pawls.

Abstract: A method and apparatus for automatically producing a wire harness. A plurality of wiring blocks are arranged on a workbench. Each wiring block has a wire clamping section, a wire cutting section, and a terminal press attaching section. The wire cutting section and the terminal press attaching section can be separated from the wire clamping section. This structure makes it possible to automate a series of operations including wire cutting, wire peeling, and terminal attaching operations.
