Title: Vane pitch-angle controller for wind-power generation
Inventor: SUETSUGU KAZUYOSHI
IPC: F03D7/02
Filed: 1983-10-06
Abstract: PURPOSE:To previously prevent the generation of the trouble such as breakage of vanes, etc. by installing a means for detecting the stress applied onto vanes and controlling the pitch-angle of a vane so that a detected stress does not exceed a prescribed value when trip is generated in wind-power generation. CONSTITUTION:The pitch-angle instruction of a vane is input into an adder 3 through a switching relay 1 and an analogue memory 2 during normal operation, and the pitch angle of the vane is controlled by the output signal of the adder 3. Since the switching relay 1 cuts-off the output supplied into the analogue memory 2 when trip is generated, the pitch-angle instruction immediately before trip is memorized into the memory 2. At the same time, a switching relay 4 is switched so that the deviation signal determined by a signal generator 7 is transmitted to an integrator 5. Then, pitch operation is determined on the basis of the value obtained by adding, in the adder 3, the outputs of the memory 2 and the integrator 5. Thus, application of an abnormal stress onto the vane is prevented, and the generation of trouble can be previously prevented.

Title: Linear scale
Inventor: KONISHI EIJI
IPC: G01D5/245
Filed: 1988-07-27
Abstract: PURPOSE:To obtain high resolution by separating the output sine wave signal of a magneto-resistance element into a pulse signal proportional to the number of magnetic poles and a pulse signal by a comparator and a pulse signal corresponding to the position shift in a magnetization pitch interval by an amplifier and an A/D converting circuit, and processing those signals. CONSTITUTION:The magneto-resistance element 1 is so constituted that four resistance elements 2 are arranged at intervals a half as large as a magnetization pitch while having their lengthwise directions almost in parallel and constitute a bridge circuit. Further, one of sine wave signals outputted by the element 1 is made into a pulse signal by the comparator 4 and outputted to a counting circuit 5 and the other is converted into a pulse signal through the amplifying circuit 7 and A/D converting circuit 8 and inputted to the circuit 5. Then the circuit 5 puts the input pulses together and outputs a digital signal which is proportional to the displacement to a display circuit 6.

Title: Horizontal rolling mill
Inventor: TAZOE NOBUHIRO
IPC: B21B13/14
Filed: 1992-06-22
Abstract: PURPOSE:To provide a horizontal rolling mill in which thrust forces that are generated by roll cross are stably supported by a simple mechanism and only work rolls with which highly accurate shape control is achieved are crossed. CONSTITUTION:Only the upper and lower work rolls 11, 12 are crossed, supporting plates 22 are freely turnably mounted with pins 23 perpendicular to the roll chocks 16 for the work rolls 11 on which the thrust forces are generated by roll cross and the thrust forces are received by holding both faces of the thrust receiving parts 24 of these supporting plates 22 between the wheels of support blocks 26 which are attached to housings 17. Even when the work rolls 11, 12 are crossed, the supporting plates 22 are made to be always in parallel to the traveling direction L of sheet and the thrust forces are supported in the stable state by the simple mechanism. Since the thrust forces that are generated by roll cross are approximately equal in magnitude and opposite in direction, the mutual roll chocks with which the thrust forces can be cancelled are mechanically connected. In this way, the major part of the generated thrust forces is cancelled.

Title: Method for blending additive in thermoplastic polymer
Inventor: ANANDA EMU CHIYATAJII
IPC: B29K105/06
Filed: 1991-07-26
Abstract: PURPOSE: To blend an additive in a polymer without melting polymer particles by suspending or entraining the thermoplastic polymer particles and the additive during blending in a gas medium using a continuous supply rapid/high strength mixer, and further, blending both materials in such a way that the additive is applied on the surface or the interior of the polymer particles. CONSTITUTION: Thermoplastic polymer particles and an additive are blended while these materials are subjected to a suspension or entraining process in a gas medium using a continuous supply rapid/high strength mixer, and the additive is blended in such a way that it is applied to the surface or the interior of the polymer particles. This process is performed continuously without the use of a binder and in a short residence time in the mixer. The additive is blended into the granular polymer, e.g. polypropylene particles by colliding with each other at a high speed and thus the polymer particles and the additive are subjected to a rapid/high strength mixing process. The molten surface of the additive and/or the polymer prompts the blending of the additive into the polymer and the obtained polymer particles can be directly sold to a customer without the necessity of pelletizing them.

Title: Power source zero cross pulse circuit
Inventor: WADA MASAMI
IPC: H04B3/54
Filed: 1989-07-20
Abstract: PURPOSE:To obtain a miniaturized and inexpensive power source zero cross pulse circuit by comprising a stabilizing power source of a first resistor, a Zener diode, a transistor, and a capacitor, and converting a charge current to the capacitor with a photocoupler. CONSTITUTION:The stabilizing power source is comprised of the first resistor 2, the Zener diode 3, the transistor 5, and the capacitor 6. Namely, when a pulsating current goes less than a stabilizing voltage, the transistor 5 is turned off, and the input diode of the photocoupler(PC) 4 is de-energized, therefore, the output transistor of the PC 4 is also de-energized, and the stabilizing voltage appears at the connecting point of the output transistor 5 and a second resistor 7 as a power source zero cross pulse (ZVP). Adversely, when the pulsating current exceeds the stabilizing voltage, the transistor 5 is energized to keep the potential of the capacitor 6 constant, and the input diode of the PC 4 is energized, therefore, the output transistor of the PC 4 is energized, and the pulse ZVP appearing via the second resistor 7 disappears. In such a way, it is possible to realize the miniaturized and inexpensive ZVP circuit as a whole.

IPC: G03G15/20
Filed: 1988-07-26
Abstract: PURPOSE:To easily treat a paper jam without deteriorating the fixing property of the fixing device by providing a cover by which the carrying path after a roller pair can be opened while the pressure-contacting state of the roller pair is maintained. CONSTITUTION:When a handle 21 is turned around a shaft 22 fixed to a cover 19, the handle 21 comes off from the fixing joggle 23 of a fixing device main body and the cover 19 can be turned around a hinge 20. A pawl 14 is separated far from the position where transfer paper is separated from a roll 12 and a upper carrying section 17 is also separated far from the low carrying section 18. Thus a sufficient space for treating a paper jam is obtained. When such constitution is adopted, the paper jam treatment becomes easier and deformation and breakage of the pawl 14 caused by the opening and closing of the cover 19 can also be avoided.
