Title: Exhaust bypath for supercharger
Inventor: UDAGAWA TETSUO
IPC: F02B37/18
Filed: 1987-10-09
Abstract: PURPOSE:To prevent degradation of engine exhaust efficiency by stepping the area of a scroll path at a position where an exhaust bypath opens, thereby approximately equalizing pressure at the inlets of a turbine. CONSTITUTION:Exhaust bypaths 12a, 12b have such function as to bypass excessive exhaust gas to a turbine impeller 1 under high speed heavy load operation of an engine 5 and to control turbine rotation. Since the bypath 12b arranged in a scroll path 10a near to a turbine outlet path 11 is longer than the bypath 12a, path resistance is increased. Area of the scroll path 10b is made larger than that of the scroll path 10a so as to cancel the differential path resistance. Consequently, pressure at the outlet sections 7a, 7b of an exhaust manifold 7a, 7b is equalized, thus preventing degradation of exhaust efficiency of the engine 5.

Filed: 1987-10-08
Abstract: PURPOSE:To secure good dynamic sensitivity by making a base end side of an armature so as to perform its circular motion via a rocking lever being driven by a pushbutton. CONSTITUTION:When a control element 21a of a pushbutton 21 is pushed, a lever part 21b is rotated clockwise with a fulcrum part 21c as the center, and since a free end 23 of a rocking lever 23 is rotated counterclockwise centering on the fulcrum part 23a by a pressing projection 21d, a base end 18b of an armature 18 is pushed down. When the fulcrum part 18b between this armature 18 and the lever 23 goes beyond a change point dependent upon the position of a fulcrum part 26a between an inner end 13a of a common terminal strip 13 and a compression spring 26, this spring 26 operates for open, and thereby a traveling contact 19 is dissociated from a normally closed fixed contact 17 by its snap action, then it comes into contact with a normally opened fixed contact 16, thus an interval between the common terminal strip 13 and a nor mally opened fixed terminal strip 14 is electrically closed. According to this constitution, the rate of variation is pressing force to an operating distance in and around an operation limit position becomes lessened so that good dynam ic sensitivity is thus securable.

Title: Thermosensitive recording medium
Inventor: AMANO TETSUYA
IPC: B41M5/28
Filed: 1987-10-08
Abstract: PURPOSE:To provide a clear, high-density image requiring very low energy without losing sticking, head-maching or other characteristics by using at least two foaming plastic fillers of different expansion ratios. CONSTITUTION:At least two foaming plastic fillers of different expansion ratios are heated to provide a foam layer between a carrier and a thermosensitive coloring layer. In such a structure, these foaming plastic fillers of different expansion ratios fill spaces among their particles. This provides a foam layer having a uniform smooth surface. Further, the foam layer serves as a heat insulator, and the energy from a thermal head is effectively absorbed in the thermosensitive coloring layer, thereby improving heat sensitivity. The foaming plastic fillers are preferably selected so that the ratio of the minimum to the maximum expansion ratios may fall within a range of 1:1.5-20. An undercoating composed mainly of a filler and a binder may be provided between the foam layer and the thermosensitive coloring layer if the foam layer is required to have a more uniform surface.
