Title: Tension imparting device of looper thread
Inventor: NISHIMURA TOSHIO
IPC: D05B63/00
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To reliably prevent the occurrence of skipping stitches caused by excessive length by providing tension to a looper thread between a looper and bobbin thread reel so as to prevent excessive length generated to a looper thread by a bobbin thread reel from resulting in slack on the delivery side of the looper. SOLUTION: The tension imparting device 1 of a looper thread 24 stretched from a looper 21 to a bobbin thread reel is provided with a thread handling area forming piece 5 and auxiliary thread handling area forming piece 6 arranged with a predetermined space in-between and a spring 7 arranged between both the pieces 5 and 6. Tread holes 5a and 6a are formed on the pieces 5 and 6 respectively, and a hook part 10 is provided for the spring 7. Therefore, the hook part 10 comes into contact with the looper thread 24 stretched over both the pieces 5 and 6 from the underside, and the spring 7 biases the hook part 10 in the direction out of a thread handling area, i.e., over both the pieces 5 and 6.  By this, the looper thread 24 is drawn upward by the biasing of the spring every time when excessive length occurs in the looper thread 24 according to the rotation period of the bobbin thread reel to maintain the tension of the looper thread 24 within a predetermined range.

Title: Toner with external additive, image forming device and method of forming image
Inventor: KOJIMA KISHO
IPC: G03G9/097
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To provide a toner with external additives which enough develops the effect of the external additives and which has excellent transfer property by controlling the coating rate of the maximum average particle diameter of the external additive applied on a toner having a specified shape coefficient to a specified range and controlling the coating rate, volume average particle diameter of the toner particles and the volume average particle diameter of the external additive having the maximum average particle diameter to satisfy a specified expression. SOLUTION: The toner with external additives is produced by applying an external additive on toner particles having <=134 shape coefficient. The coating rate x of the external additive having the maximum average particle diameter of the external additive applied to the surface area of the toner particles ranges 15 to 100%, and the coating rate x (%), the volume average particle diameter D (μm) of the toner particles, and the volume average particle diameter d (μm) of the external additives having the maximum average particle diameter satisfy the expression. If the shape coefficient of the toner with an external additive exceeds 134, the transfer property of the toner decreases and irregularity in the transfer appears especially in a transfer medium, especially a recycled paper having small surface smoothness. The shape coefficient of the toner particles is preferably <=125.

Title: Control of injection molding machine
Inventor: HIROZUMI HITOSHI
IPC: B29C45/80
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling an injection molding machine capable of preventing the generation of resin scorching to enhance the quality of a molded product. SOLUTION: A movable mold 2 is pressed to a fixed mold 1 to perform mold clamping and an ejector pin 17 is allowed to advance to protrude the front end of the ejector pin 17 within the cavity space 23 formed between the movable and fixed molds 2, 1 by set quantity and the cavity space 23 is filled with a resin. The ejector pin 17 is allowed to retreat accompanied by the filling with the resin. The vol. of the cavity space 23 becomes large by allowing the ejector pin 17 to retreat and the pressure of the air in the cavity space 23 becomes low. Since the amt. of the air remaining in the cavity space 23 is reduced by the filling amt. of the resin at a point of time when the filling with the resin is completed, the generation of resin scorching can be prevented.

Abstract: PURPOSE:To reduce the frequency of brake operation by shifting down an automatic speed change geer at the time of judging the generation of rear-end collision with a preceding vehicle at the degree of the reducing speed of an engine brake at the time of confirming speed reducing will. CONSTITUTION:At the time of judging that an inter-vehicle distance is less than an alarm inter-vehicle distance, a control unit 14 turns on an alarm lamp 24a and drives an alarm buzzer 24b. At the time of judging that accelerator aperture is <=5%, the unit 14 calculates an inter-vehicle distance, a relative speed and relative acceleration/deceleration required after removing a food from an accelerator pedal. Whether the continuation of current traveling causes the generation of rear-end collision with the preceding vehicle or not is judged in accordance with the increment/decrement of the relative speed between the preceding time and current time or the inter-vehicle distance. At the time of judging the generation of rear-end collision with the preceding vehicle at the current decelerating speed, a shift-down command is outputted to a controller 25 in an automatic speed change geer to shift down the speed reducing step only by one step. Consequently engine brake is activated.
