Filed: 1985-12-10
Abstract: PURPOSE:To enhance the quality of a product by always securing sufficient filling pressure, by a method wherein a hydraulic circuit is changed over to a pressure control valve side for holding pressure when the leading end part of an injection molten substance extruding member passes a preset position and, thereafter, injection pressure further reaches predetermined set pressure for changing over held pressure to start the timing of a timer and held pressure is subsequently changed over to plural stages.

Filed: 1984-12-26
Abstract: PURPOSE:To enlarge the substrate surface which contributes to heat radiation and to provide optical circuit elements, each of which is composed of a heating unit and optical waveguide, at a high density, by providing grooves between adjacent optical circuit elements. CONSTITUTION:Optical waveguides 2 and 3 and a heating unit 5 are installed to a TO type optical circuit element 7 formed on a substrate 6 and, when the heating unit 5 produces heat, the refractive index of the waveguides changes and the rays of light made incident on the waveguide 2 advance under the same condition or move to the waveguide 3. By providing grooves 9 between adjacent elements 7, the substrate surface area is increased so as to make the heat radiation after heating quicker and accelerate the thermal optical effect. Therefore, intervals between the elements 7 can be narrowed by the increased quantity in substrate surface area and the TO type optical circuit elements can be mounted at a high density.
