Patent JP-H01313263-A (JP)
Title: Winding unit
Inventor: MATSUYAMA KOJI
IPC: B65H54/32
Filed: 1988-06-10
Abstract: PURPOSE:To make it suitable for various packages with one traverse motion alone as well as to dispense with any replacer for a grooved drum by setting up a double traverse motion capable of a setting change in accord with width of a package where reciprocating length of the grooved drum has been set. CONSTITUTION:A first traverse in a double traverse motion 7 is in motion to guide yarn from one side of width of a package P to the other side or the vice versa with the reciprocating traverse of a grooved drum 15. A second traverse is guided by a groove 15a of the grooved drum 15 at each time this grooved drum 15 rotates a turn, and it acts to make the yarn move right and left one time. These first and second operations are overlapped each other, whereby reciprocating length of the grooved drum 15 is changed for its setting in accord with width of various packages set to a winding unit. Consequently, such a requirement that some grooved drums 15 being conformed according to types of the package P are prepared for is made neglectable and, what is more, any replacer for this grooved drum 15 also becomes useless.

Title: Crankshaft of internal-combustion engine
Inventor: MATSUNAGA MORISHIRO
IPC: F16C3/06
Filed: 1984-07-09
Abstract: PURPOSE:To prevent stress concentration on a specified spot of a crankshaft and to improve fatigue breaking limits by providing an output side journal having a fly wheel with a groove for dispersing stress formed on the peripheral surface thereof in a crankshaft. CONSTITUTION:In a crankshaft of a 4-cylindered engine, when combustion pressure is applied to the fourth pin journal 34 from direction of an arrow A by a connecting rod of a piston, a fly whel 6 having large mass will not deform, but the third journal 23, an arm 46, the fourth pin journal 34, an arm 45 and the third pin journal 33 deform. Stress concentrates on a joint point B between the fourth pin journal 34 and the arm 46. In this case, a circular groove 5 is disposed on the peripheral surface of the third journal 23 on output side extending over the whole periphery. Thus, the stress concentrated on a spot is dispersed on the base portion C of the circular groove 5 to stress on the above joint point B and improve fatigue breaking limits.

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To easily hook fingers on to a finger hooking part, while preventing other members from being hooked. SOLUTION: A finger hooking part 14 is protrusively formed on the outer surface of a male housing 10, and a rib 15 linking to the finger hooking part 14 is also protrusively formed. Event if other members such as wires approach to the finger hooking part 14 along the outer surface of the male housing 10, they can settle without being hooked to the finger hooking part 14, since they would have to run on to the rib part 15 in order to be hooked. Since there is no fear that other members are hooked to the finger hooking part 14, fingers can be easily hooked by heightening the finger hooking part 14.

Abstract: PURPOSE:To obtain an inexpensive master batch having a high perfume content and low evaporation loss of perfume during molding, by adding the perfume and a polyolefin in turn to an ethylene/vinyl acetate copolymer powder with high speed agitation and kneading the mixture. CONSTITUTION:50pts.wt. or above perfume is added to 100pts.wt. ethylene/vinyl acetate copolymer (EVA), and the mixture is kneaded at a high speed. Polyolefin powder is added thereto and agitated at a high speed to obtain a granular master batch.
