Abstract: A substrate treatment apparatus includes: a substrate holding unit which horizontally holds a substrate; a liquid droplet nozzle which generates droplets of a treatment liquid which are sprayed on a spouting region on an upper surface of the substrate held by the substrate holding unit; and a protective liquid nozzle which spouts a protective liquid obliquely onto the upper surface of the substrate held by the substrate holding unit for protection of the substrate to cause the protective liquid to flow toward the spouting region on the upper surface of the substrate, whereby the spouting region is covered with a film of the protective liquid and, in this state, the treatment liquid droplets are caused to impinge on the spouting region.

Abstract: An object of the present invention is to accurately detect an abnormality in an EGR device for an internal combustion engine with a supercharger, or more specifically, the inability of an EGR valve to fully close due, for instance, to trapped foreign matter. To achieve the object, the present invention provides an abnormality detection device for the EGR device. The abnormality detection device includes an O2 sensor which is installed in an EGR path and disposed on the exhaust path side relative to the EGR valve, and an A/F sensor which is installed in the exhaust path and disposed downstream of a connecting portion between the exhaust path and the EGR path. The abnormality detection device uses a signal output from the O2 sensor and a signal output from the A/F sensor to judge whether the EGR device is abnormal.

Abstract: At a vibration applying position, ultrasonic vibration is applied upon a liquid film which is on a surface of a substrate. Concurrently with this, at a drop arrival position which is different from the vibration applying position, drops of a cleaning liquid are supplied to the liquid film, whereby wave-generating vibration which is different from the ultrasonic vibration is applied upon the liquid film. This dramatically improves removal of particles adhering to the surface of the substrate as compared with mere application of ultrasonic vibration. Hence, even when the output, the frequency and the like of the ultrasonic vibration are set to such an extent not damaging the substrate, it is possible to effectively remove particles with the wave-generating vibration and favorably clean the surface of the substrate.

Abstract: In an injection compression molding method, dies are clamped with low pressure and a melted thermoplastic resin composition is filled in a cavity space from a gate while moving the cavity space relative to the gate, and then the dies are clamped with a high pressure substantially simultaneously with completion of the filling to compress and form the thermoplastic resin composition filled in the cavity space. Since the thermoplastic resin composition containing a high content of thermally-conductive filler such as an electrically-conductive filler can be injected and compressed to be molded, the injection compression molding method can be applied in manufacturing molding such as a fuel cell separator and a flat antenna.

Abstract: The method of forming a light-weight, fiber-reinforced, particularly glass fiber-reinforced-thermoplastic resin product includes the steps of melting and mixing thermoplastic resin pellets containing parallely oriented fibers 2-100 mm long, injecting the melted resin into a cavity which is closed so that its volume is smaller than that of the final molded product, and, before or after the resin injection is completed, opening the cavity until its volume is equal to that of the final molded product. Unlike the conventional injection-molded products, this product does not require a foaming agent and, if it uses any, requires only a small amount of foaming agent. The product thus formed is light in weight and has fibers uniformly entangled inside, providing an excellent appearance of the surface. Further a skin layer is formed over the surface. These features combined with the reinforcement by the glass fibers offer high strength and high stiffness.
