Abstract:
According to the present invention there is provided a highly reliable position sensor capable of preventing the entry of foreign matters such as water and dust from the exterior into a receptacle chamber formed within a housing. Formed in the housing are a mounting opening to be mounted in a sealed state to a throttle body and a receptacle chamber having an opening. The receptacle chamber and the mounting opening are partitioned from each other by a partition wall. A sensor body is mounted into the receptacle chamber and the opening of the chamber is covered with a cover, then a clearance formed between the opening and the cover is filled and sealed with a thermosetting resin such as an epoxy resin. A communication hole for communication between the receptacle chamber and the mounting opening is formed through an operating shaft which is rotating a sliding-element receiver of the sensor body. While the thermosetting resin is heated, the air expanded in the receptacle chamber is allowed to escape through the communication hole to the exterior. After a throttle position sensor as the position sensor has been attached to the throttle body, the communication hole formed in the operating shaft is shut off from the exterior by the mounting surface for the throttle body.
Abstract:
A multi-slider electrical assembly comprises a metal case having a channel-shaped cross-section mounted on a substrate. The case has parallel slits, and guide blocks are spaced apart in parallel within the case for guiding a plurality of sliders extending through the slits. The case has an engage projection and semi-projections on each side thereof formed at each corner on its side walls. The engage projections are bent in contact with metal layers on the bottom surface of the substrate, and the semi-projections bear on grounding layers on the upper surface of the substrate, in order to hold the substrate therebetween without crushing it and to provide a good ground for the case.
Abstract:
A three-dimensional simulation apparatus includes a memory configured to store form information of a sheet flexible object model formed of first polygons and another object model, an interference determination unit configured to determine whether the sheet flexible object model formed of the first polygons in three-dimensional simulation space interferes with the other object model on the basis of the form information stored in the storage unit, a polygon creation unit configured to form second polygons by dividing the sheet flexible object model in a longitudinal direction when it is determined that the sheet flexible object model interferes with the other object model, and a shape computation unit configured to determine a shape of the sheet flexible object model using the formed second polygons in consideration of a shape of the other object model.

Abstract:
A wiper holder to which a wiper is attached has an attachment surface including a positioning boss configured to position the wiper by being passed through a positioning hole in the wiper, a positioning protrusion configured to position a first edge of the wiper, and a swage boss configured to receive a second edge of the wiper. The first edge of the wiper contacts the positioning protrusion to position the first edge of the wiper and the wiper is secured to the wiper holder by the swage boss being swaged while the positioning boss is passed through the positioning hole in the wiper and the second edge of the wiper being received by the swage boss.
Abstract:
A fluorine-containing polymer comprising a fluoroalkyl alcohol (meth)acrylic acid derivative represented by a general formula, CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR═CH2 (in the formula, R is a hydrogen atom or a methyl group, n is an integer of 1 to 6, preferably 2 to 4, a is an integer of 1 to 4, b is an integer of 0 to 3, and c is an integer of 1 to 3) containing in 5 to 100 wt % as a polymerization unit. A organic solvent solution or aqueous dispersion of the fluorine-containing polymer is effectively used as, for example, a surface-modifying agent such as a water- and oil-repellent or an oil barrier.
