IPC: D05B65/02
Filed: 1989-12-28
Abstract: PURPOSE:To prevent stitches such as a so-called 'nest', by a method wherein a knife is provided at the upper part of a shuttle body, and the title device is composed so that in specified number of the stitches after the next start of a sewing-machine, when a severed end of a needle thread is on the rear side of a workpiece, the knife is operated and the severed end of the needle thread is cut. CONSTITUTION:After the end of sewing, a needle thread and a lower thread are severed from a workpiece by the operation of a thread-cutting device 10. In the first stitch after the next start of sewing, when a sewing needle 71 is moved downward, and nearly reaches a lower dead point, a solenoid 50 is operated by a sensor for detecting rotation. After that, a connecting lever 43 is turned clockwise, and a connecting link 42 is pulled downward, and a roller arm 34 is turned downward centering around a spindle 35. In this way, the roller 35 is engaged with a cam groove on a thread-cutting cam 32, and a knife-driving arm 37 is oscillated with the rotation of a hook shaft 30, following which a connecting link 52 is vertically moved and turns a driving shaft 54, and a moved knife 60 is turned clockwise. After that, when the sewing needle is free from a workpiece 70, the moved knife 60 is turned counterclockwise along the figure line of the cam groove on the thread-cutting cam 23, and cuts a severed end of the needle thread together with the fixed knife 62. In this way, the severed end of the thread does not appear on the surface side and the quality of sewing is improved.

Title: Mounting structure for accelerator cable for vehicle
Inventor: YUNAGA TOSHIFUMI
IPC: B60K26/04
Filed: 1997-12-09
Abstract: PROBLEM TO BE SOLVED: To provide the mounting structure for an accelerator cable for a vehicle simply constituted to suppress transmission of noise from the engine room side to the car interior side. SOLUTION: An inner cable 8a is inserted in a cable holding member 12, and a cylinder member 17 is arranged in a state to extend to the one end part side of the inner cable 8a running through the hole 9a of a noise insulation material 9. A groove 18a is formed in the cylinder member 17. A plate 19 made of an elastic material to press a noise insulation material against a dash panel 1 is mounted in the groove 18a. Since the cylinder member 17 performs a function to prevent the occurrence of interference between the noise insulation material 9 and the inner cable 8a, the hole of the noise insulation material 9 is set to size small enough to allow only the passage of the cylinder member 17 through the hole 9a of the noise insulation material 9.  As noted above, by decreasing the size of the hole 9a of the noise insulation material 9, transmission of noise on the engine room 4 side to the car interior 2 side is suppressed. Noise insulation treatment is achieved by mounting the cylinder member 17 on the cable holding member 12, whereby in noise insulation treatment, structure is not complicated and in turn, assembly properties are not deteriorated.

IPC: H02J3/26
Filed: 1993-11-18
Abstract: PURPOSE:To improve the utilization factor of a three-phase AC power supply system by connecting a parallel circuit composed of a capacitor and first variable reactor between the lines of one of the phases which are different from a load phase in which a single-phase load having a 1.0 power factor is equivalently connected to the power supply system and second variable reactor between the lines of the other one of the phases. CONSTITUTION:A load 2 is connected between A-C phase lines and a parallel circuit 5 constituted by connecting in parallel a capacitor 3 and variable reactor 4 is connected between A-B phase lines across which the phase of power supply voltage is delayed by 120 deg.. In addition, a variable reactor 6 is connected between B-C phase lines across which the phase of power supply voltage is delayed by 120 deg. front the A-B phase lines. Then, as the electric power to the load 2 gradually increases, the reactors 4 and 6 are adjusted by means of driving motors 21 and 22 so that the reactive power generated by the capacitor 3 and reactors 4 and 6 can respectively become the 1/3 of their load losses in accordance with the electric power to the load 2. Therefore, the power supply currents flowing through the line of each phase are balanced and it becomes unnecessary to set the capacity of a three-phase AC power supply system in surplus.

Filed: 1994-12-28
Abstract: PURPOSE: To facilitate mounting a cross cartridge in and demounting it from a turn table, by interposing an elastic member between a tightening member and the turn table, and loading elastic force between a tapered surface and an engaging surface. CONSTITUTION: When a wrench is rotated, a tapered surface 33 presses an engaging surface 43 to press a cross cartridge 1 in the downward direction. When reaction force acting in a stop part 29 from the engaging surface 43 is increased to a fixed value or more, a belleville spring 25 is started to be distorted, and force in accordance with this distortion amount acts between the tapered surface 33 and the engaging surface 43, that is, between the cross cartridge 1 and a turn table 4. Further when the wrench is rotated, contact of the engaging surface 43 is transferred from the tapered surface 33 to a flat surface 34, and a rod comes into contact with the second stopper, to stably fasten the cross cartridge 1 to the turn table 4.

Title: Boot for mechancal shaft coupling
Inventor: MIYAMOTO KENJI
IPC: F16J15/52
Filed: 1992-12-18
Abstract: PURPOSE:To improve fatigue resistance by preventing centralized application of a stress on a boundary between first and second ring parts and a belly part when the boot is deformed along with rocking of a drive shaft and reducing the generation of the strain of the boundary part. CONSTITUTION:When a drive shaft 3 is rocked centering around a state that a joint angle is 0 deg., a compression stress or a tensile stress is exerted on a boundary part T between a ring part 5 and a belly part along with deformation of a boot B, and a strain is generated. However, even when the stress is exerted, the stress is uniformly dispersed since a protrusion part 13 is formed at the boundary part T of the ring part 5 where a strain is generated and the thickness (a) of the protrusion part 13 is increased to a value higher than the thicknesses (b) and (c) of the ring part 5 and the belly part 6. This constitution causes reduction of the generation of the strain of the boundary part T and suppression of the generation of a crack at the boundary part T.

Abstract: PROBLEM TO BE SOLVED: To provide a member with a screw groove at its inner periphery in the form of linearly advancing in a first sleeve by fragilely combining a second sleeve and a member provided with a screw groove on its inner periphery and separating it by a rotating function after insertion to the first sleeve. SOLUTION: An attachement 24 being the end part member of a holding member 12 at a position away from a packed material 22 is combined with the residual part of a holding member 12 via a previously set breaking point 26. At the time of rotating the member 12 with respect to a handle 10, the attachment 24 is continually rotated with respect to the handle 10 by the operation of a rib. As a result, the previously set breaking point 26 is broken. Once this previously set point 26 is broken, the attachment 24 constitutes a member with the screw groove on its inner peripheral and is rotated with respect to the member 12 with the handle 10. As a result, a packed material mounting member 16 incorporating packed material is pressed out to the left in and axial direction from an opening.
