Title: Power transforming device
Inventor: FUKAZAWA KATSUMI
IPC: H03K17/12
Filed: 1998-07-23
Abstract: PROBLEM TO BE SOLVED: To prevent current balance between plural switching elements from becoming worse and to surely perform a prescribed power transformation by respectively connecting a resistance element of a prescribed value to the emitter side of each switching element from the viewpoint of a gate controlling power source. SOLUTION: Resistance Re1 and Re2 of prescribed values are connected to emitter sides E1 and E2 of switching elements S1 and S2 in gate distribution lines from a gate control power source Vg. Circulating current that flows to the distribution lines of the emitter sides does not become large current, because it flows through the resistances Re1 and Re2. Also, because the circulating current has a short time constant and attenuates soon, it becomes completely zero by the time the elements S1 and S2 are turned on next time. Therefore, the balance of current does not become worse at parallel connection of plural switching elements. Also, because unwanted circulating current does not flow, the heat generation of the distribution line does not increase unnecessarily.

Title: Dyeing method
Inventor: KOBAYASHI TOSHIRO
IPC: D06P7/00
Filed: 1991-08-20
Abstract: PURPOSE:To enable the dyeing of a cloth without causing dyeing speck by controlling the pressure difference between the inside and the outside of a tubular object to be dyed and the frequency of a variable speed apparatus for feeding a dyeing liquid to respective specific standard values. CONSTITUTION:A dyeing liquid is passed from the inside to the outside of a tubular object to be dyed such as a yarn bobbin. The dyeing apparatus having the above action is provided with a pressure difference gauge to measure the pressure difference between the inside and the outside of the tubular object and an apparatus to enable the change of the feeding rate of the dyeing liquid. A sample is dyed with a dyeing tester having the same structure as the above dyeing apparatus to confirm the pressure difference P2 and the frequency f2 of the variable rate feeding apparatus. The sample is dyed with the dyeing apparatus and the frequency f3 corresponding to the pressure difference of P2 is determined. The dyeing object is dyed with the tester to the optimum level and the frequency f4 is determined. The standard dyeing frequency fS for the optimum dyeing of the dyeing object with the dyeing apparatus is calculated by the formula f3/f2Xf4=fS and the variable rate feeding apparatus is adjusted in such a manner as to keep the frequency fS.

Title: Communication fault detection device
Inventor: YAMANE ISAMU
IPC: H04B17/10
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To speedily detect the fault caused by the delay of a common clock signal and to appropriately deal with the fault by specifying a fault factor range at the time of a communication fault caused by step-out in the communication which is subordinately synchronized with the common clock signal. SOLUTION: When a communication fault owing to step-out is detected with an opposite device in a transmission/reception part 18-1, the transmission/ reception part 18-1 informs a signal processing part 16 of it. The signal processing part 16 gives the instruction of the transmission of a test clock signal with a -1/8 clock phase to the transmission/reception part 18-1 to the controller 28 of a clock control part through a bus. The controller 28 receives the instruction, controls a switch part 34 and returns a response signal to the signal processing part 16. The switch part 34 changes over a system to the supply of the test clock signal with the -1/8 clock delay phase from a common clock signal to the transmission/reception part 18-1 with the control of the controller 28.  Thus, the transmission/reception part 18-1 executes communication in synchronizing with the test clock of the -1/8 clock phase.

IPC: B65H23/025
Filed: 1984-10-05
Abstract: PURPOSE:To provide adjustability for the width stretching force in good response to the quality and condition of a fiber product by accomplishing such an arrangement that two pairs of transport plates having a regular polygonal profile installed to the left and right on the periphery of a drive shaft are opened to the left and right by cams installed on the shaft periphery while they are transporting a fiber product of long size. CONSTITUTION:When a drive shaft 7 rotates, transport plates 8, 9 of a transport roll 6 rotate together with the shaft 7 to push ahead a fiber product 3 loaded thereon, and at the same time are moved toward the shaft end of the left and right shafts 7 to be opened, as they are engaged with a groove cam 20a formed at a cylindrical member 20, and consequently a force to stretch the width of the fiber product 3 is applied thereto. Thus wrinkles in the direction fore and aft are stretched. Further, if the fiber product 3 equipped initially with an elongation in its width direction is wound up while given a tension in the longitudinal direction to have led to narrowing, the width can be recovered, and the operation start position is restituted by one turn. The fiber product 3 is supported danglingly over a web stretching table 2 and subjected to a stretch when the body 1 of web stretching machine moves, and is cut into a specified length. This ensures application to a variety of fiber products, whose widths can now be stretched with good performance.

Abstract: PURPOSE:To stack empty cans in the empty space of a vehicle for recovering empty cans and to improve operation efficiency by conveying and screening the collected empty cans on the vehicle, compressing the cans to iron mass and aluminum mass and discharging the mass on the vehicle. CONSTITUTION:Empty cans are charged into an empty can charging part 4 disposed in the rear part of a cargo box 2 placed on the frame 3 of a vehicle 1 for recovering empty cans. The empty cans are then detained by the detaining part 8a of the conveyor belt 8 of a belt conveyor 7 and are conveyed to hoppers 5, 6. When the empty cans come near a magnet roller 9, the iron cans are attracted by the magnetic force of the roller 9 and is rotated along the belt 8. On the other hand, the aluminum cans fall straightly into a front hopper 5 for aluminum cans. The iron cans receive no longer the influence of the magnetic force near the part passing through the hopper 5 for the aluminum cans and fall into the hopper 6 for the iron cans. The iron cans are then charged into a compressor 10 by which the cans are compressed to iron mass. The iron mass is discharged through a discharge port 10b onto a roller conveyor 15 and is stacked on the box 2. The aluminum mass is stacked by the similar operation.
