Title: Method for treating textile fiber
Inventor: BURUUSU UEIN BONBA
IPC: D06M15/00
Filed: 1991-03-19
Abstract: PURPOSE: To effectuate chemical treatment that follows and reduce the BOD of an effluent by modifying the surface of textile fibers by treating the textile fibers with a treatment solution obtained by combining a polygalactomannan having a molecular weight greater than a specific value with an oxidizing agent. CONSTITUTION: The surface of textile fibers is modified by adding the textile fiber material with a treatment solution obtained by combining a polygalactomannan having a molecular weight exceeding 500,000 with an oxidizing agent, particularly sodium persulfate, of 0.1-1 wt.% of the polygalactomannan and by washing and removing depolymerized polygalactomanan and oxidized by-products after a heat treatment at 95 deg.C. For example, when treating with a contamination resistant chemical material, the material amount is lowered, the amount of effluent BOD is reduced and modification is made to obtain a good feel to hand. For the most preferable textile fiber treatment, guar gum having a malecular weight exceeding 1,000,000 is used as the polygalactomannan in combination with a 0.3-0.8 wt.% oxidizing agent.

Title: Flow rate regulator valve with pressure compensation
Inventor: SUZUKI YASUHIRO
IPC: F16K17/30
Filed: 1994-02-28
Abstract: PURPOSE:To obtain excellent pressure compensation performance which compensates the pressure difference across a restriction hole to a constant value by reducing the slide resistance of a pressure compensating valve which is fitted onto a flow adjustment member and inserted into a slide hole in a valve body and smoothly sliding the pressure compensating valve in the axial direction. CONSTITUTION:The flow rate adjustment member 10 which sets the opening of the restriction hole 15 variably engages an operation member 6 while allowing a radial movement and inhibitting an axial movement, and a spring 11 is interposed between the operation member 6 and flow rate adjustment member 10, which are axially extended with the spring force. Consequently, when a fixation member 9 is pressed against the end surface of a lid member 5 so as to fix the dial member 7 that the operation member 6 has so that the dial member is made impossible to rotate, moment obtained by multiplying the distance between the center of the dial member 7 and the eccentricity position where the fixation member 9 is present by the pressing force of the fixation member 9, is generated. This moment never acts on the flow rate adjustment member 10, which is not radially strained.

IPC: H03G3/02
Filed: 1986-03-12
Abstract: PURPOSE:To stabilize the amplification factor of a low frequency amplifier circuit and to improve the response to the sound volume control operation by giving a DC voltage being the conversion of a PWM signal by an integration circuit to a low frequency amplifier circuit while being divided by a voltage division circuit in response to a range switching signal in controlling the sound volume by the PWM signal having a duty ratio.

The PWM signal generating circuit 17 outputs a PWM signal of a high duty ratio. The PWM signal is converted into a DC voltage by an integration circuit 20. The voltage is divided in response to a range switching signal at a voltage division circuit 21 whose voltage division ratio is controlled by the range switching circuit 18 and amplified by a DC amplifier circuit 22. The amplified output of the circuit 22 controls the amplification factor of a low frequency amplifier circuit 23. An output voltage of the integration circuit 20 has a small ripple voltage and responds quickly to the change in the duty ratio of the PWM signal.

Although this assembly is a single capacitor from an outward appearance, it is electrically equal to two capacitors which have been connected in series. When the intermediate terminal 8 is installed, a voltage-dividing resistance can be connected across the intermediate terminal 8 and the anode terminal 4 and across the intermediate terminal 8 and a cathode terminal 5. As a result, the influence of a leakage current or the like can be eliminated, and an unbalanced state can be prevented.

Title: Rotary machine
Inventor: IMAMURA SHOHEI
IPC: H02K1/27
Filed: 1989-03-07
Abstract: PURPOSE:To short-circuit a magnetic path by separating the end section of a rotor, where a non-magnetic rotary shaft is penetrated through the central section of a magnetic board and secured thereto, from the magnetic path and establishing a closed magnetic path individually between the stators. CONSTITUTION:Front face of the magnetic pole of a permanent magnet 1 coincides with the axis of rotary shaft while the direction of flux is in parallel with the rotary shaft, and a magnetic board 2 is magnetized by the flux. Contrary to a conventional rotor, the opposite ends of the magnetized board 2 have same polarity. Consequently, the lines of magnetic force can not pass through the magnetic board 2, i.e., the rotor, and internally distributed lines of magnetic force are absorbed and converged resulting in complete polarization at the end portions. The flux is deflected by 90 deg. and split into right and left portions thus forming a split magnetic path short circuit between stators having lowest magnetic resistance. By such arrangement, flux does not pass through the rotor and a magnetic short circuit path for such as a transformer can be provided to the stator, resulting in considerable shortening of overall magnetic path.
