Title: Reed valve device of two-cycle engine
Inventor: YAMADA TOSHIYUKI
IPC: F01L1/38
Filed: 1989-09-14
Abstract: PURPOSE:To improve charging efficiency with primary compression pressure increased by closing a clearance between right and left side surfaces of a valve body and right and left internal walls of an intake hole with a seal piece of elastic material. CONSTITUTION:A valve body 3, in which right and left side surfaces are parallel with upper and lower surfaces tapered in horizontal V shape, is inserted to the hole end of an intake hole 2 of long quadrangle section protruded to one side of a crank chamber 1, and a reed valve 5 is mounted to upper and lower surfaces of the valve body 3. Here a seal piece 12 of elastic material is mounted by baking or adhesion and the like along right and left side surface edges of the valve body 3. In this way, when the valve body 3 is inserted to the intake hole 2, the seal piece 12 is brought into elastic contact with right and left internal walls of the intake hole 2 to enable a clearance 11 to be closed. Accordingly, because the volume of the crank chamber 1 can be decreased by the amount of the clearance 11, primary compression ratio of suction gas is increased to improve charging efficiency, and an engine output can be improved.

Patent JP-H0767233-A (JP)
Title: Suspension clamp
Inventor: SUZUKI MINORU
IPC: H02G7/02
Filed: 1993-08-30
Abstract: PURPOSE:To achieve a specified gripping force while lowering the nicking rate by setting the diameter of a circle being formed the wire grooves in a clamp body are collected shorter than the nominal wire groove diameter corresponding to the nominal cross-sectional area regulated by JIS. CONSTITUTION:The wire groove diameter D is set shorter by 1-5% than a conventional one. When the wires L are gripped by a conventional clamp, each strand L', L'... can move relatively freely and although a part of gap is filled it is filled unevenly thus providing a cross-section which is not right circle. When the strands L', L'... are gripped by a clamp 1, free movement thereof is blocked and the strands L', L' are joined to fill the gap uniformly. Consequently, they are clamped while sustaining the original profile and the nicking rate is lowered. The clamp 1 provides a gripping force higher than a specified level while requiring a shorter marginal length and the mechanical characteristics of wire is sustained well while lowering the nicking rate.

Title: Overlock machine capable of sewing back-tack
Inventor: SUZUTA MAMORU
IPC: D05B1/20
Filed: 1989-09-13
Abstract: PURPOSE:To surely hold the cut end of a string of loops and to make sewing constant by applying proper tension to a string of the loops, by a method wherein both first driving means for shifting a string of the loops to a stop position after movement thereof, and second driving means for shifting a tension-applying member from an evacuating position to an engaging position after a stopping member is located at the stop position, are provided. CONSTITUTION:When sewing is finished, suction devices 10, 51 are operated, and a string of loops R made of thread joined to a work is sucked toward the work-out-side of the location of a needle 5, and then it is cut with a cutting device 15. By the air blown out of shifting means 11, 52, a string of the loops after a cutting is blown toward the work-in-side of the location of the needle. At this time, if a stopping member 26 is located at a restricted position projecting on a work-supporting surface, by first driving means 28, 30, 31, a string of the loops is in contact with the stopping member and its position is restricted. After that, when the stopping member is located at a stop position lying within a work-supporting surface 2, by the first driving means, a string of the loops is secured on the work-supporting surface. Furthermore, when a tension-applying member 35 is located from an evacuating position to an engaging position by second driving means 37, 39, 40, the tension-applying member is in contact with a string of the loops, of which the position is restricted by the stopping member, and applies a tension. In this way, a string of the loops is prevented from loosening.

Title: Coupling optical system between semiconductor laser and light waveguide
Inventor: RUUDORUFU KAIRU
IPC: G02B6/42
Filed: 1988-09-22
Abstract: PURPOSE: To obtain higher coupling efficiency and high back scatter suppression by a simple method by equipping the coupling optical system with a concave mirror which is arranged in the optical path of laser light. CONSTITUTION: The coupling optical system has at least one concave mirror HSp which is arranged in the optical path S0 of laser light. Therefore, when the surface quality of the mirror surface is high enough, the concave mirror HSp reflects no light back to the laser. Further, its mirror surface is easily machined in various curved shapes by pattern pressing. For the purpose, a copper piece coated with, for example, gold is specially suitable and the surface of the concave mirror HSp is pressed in the copper piece by a punch. Consequently, higher coupling efficiency and high backward scatter suppress are obtained by the easy method.
