Inventor: YAMADA KIYOMI C O NAGOYA MACHI
IPC: D06F43/08
Filed: 1989-10-27
Abstract: The present invention is directed to a technique which comprises the steps of stopping the rotation of a treating drum (11) in a deodorizing step, introducing the outside air into a treating tank (10) through an upper opening provided in the upper portion of the treating tank (10) or the upper portion of a recovery air duct (19), simultaneously exhausting a solvent gas from the treating tank through a lower opening provided in the lower portion of the treating tank (10) or a button trap portion (12) so slowly as not to agitate the solvent gas in the treating tank by an exhaust means connected to a solvent recovery device (30a) in the condition that the treating drum is stopped, in order to replace the solvent gas in the treating tank with the outside air, and reusing the solvent gas through the solvent recovery device (30a) once or several times. In addition, the present invention is further directed to an improvement of the above-mentioned technique. According to the above-mentioned technique of the present invention, a gas throughput which is required to recover a certain amount of the solvent in the treating tank can be noticeably miniaturized and hence it can be manufactured at a lower cost, as compared with conventional ones, and air pollution and the breakage of ozone layer can be prevented. Moreover, the solvent can be saved owing to its recovery and reuse, and occupation space for the solvent recovery device can be also saved.

Abstract: A viscous damper system (5) wherein the viscosity of a fluid is used to generate damping effect when the fluid is passed through a restricted orifice (14) or slit uses an electro rheological fluid as the damping fluid. Electrodes (18, 19) are arranged to face each other across the orifice or slit so that an electric field is created in a direction which is transverse to the direction of the fluid flow in the orifice or slit. The voltage applied to the electrodes (18, 19) is controlled in accordance with a frequency of vibration of a vibrating member to be damped. The viscosity of the fluid is controlled by applying a voltage thereto, so that a desired damping effect is obtained within a wide range of frequency of the vibrating body.

Abstract: A semiconductor laser includes a groove (10) in a GaAs first current blocking layer (5), which extends to an AlxGa(1-x)As second clad layer (4) beneath the first blocking layer (5). The width of the groove (10) periodically changes between larger and smaller widths along the length of the resonator. Over the regions of the first current blocking layer (5) where the groove has the smaller width, a grating-shaped AlzGa(1-z)As second current blocking layer (6) is formed. An AlxGa(1-x)As third current blocking layer (7) is formed over the second current blocking layer (6) and the portions of the first current blocking layer (5) not covered by the second current blocking layer (6). The variation of the width of the groove (10) is provided by placing a wafer with the groove formed in the first current blocking layer (5) in a metal organic thermal decomposition crystal deposition apparatus and heating it, while causing hydrogen chloride to flow, or placing the wafer in a molecular beam epitaxial deposition apparatus and heating it while irradiating with an arsenic molecular beam, or by placing a liquid-phase epitaxial deposition apparatus and causing to pass over the wafer a melt which selectively melts the first current blocking layer (5) but not the second current blocking layer (6).

Abstract: The invention is designed to calibrate a low-level optical power by a substitution method using a pulse generating section (4) in which a light-shielding disk (4a) having a sectorial opening (4c), as a component capable of accurate optical attenuation, is rotated in a light beam to generate an intermittent pulse signal having a duty ratio corresponding to the size of the opening (4c), and the pulse signal is averaged to obtain an optical attenuation equal to the duty ratio. More specifically, while an object (2) to be calibrated is set in a given standard state, a first pulse train having a duty ratio d1 = Tw₁/Tf₁ is input to the object (2), and an average optical power value A of an output from the object (2) is measured and stored. Sub­sequently, a second pulse train having a duty ratio d2 = Tw₂/Tf₂ is input to the object (2), and the object (2) is adjusted such that an average optical power value of an output from the object (2) becomes the value A. Proper calibration can be performed by assigning the optical attenuation of the adjusted object to d1/d2.

Abstract: A digital signalling circuit employs a spaced apart driver and receiver pair in which the signal current originates at the receiver and is constant in time. The receiver chip includes a constant current source connected to the power supply plane and one termination of a signal line, a termination resistor connected across the signal line termination to the ground plane, and a sense amplifier connected to the signal line termination for sensing the voltage level or the signal line. The driver chip comprises a single switching transistor connected across the opposite end of the signal line to the ground plane, and is not directly coupled to the power supply plane. When the driver switching transistor is on, the signal line is grounded and the termination resistor in the receiver is effectively shorted out. When the driver switching transistor is turned off, the signal source current at the receiver charges up the signal line and develops a voltage across the termination resistor. Since a constant current source is used, any inductance in the circuit has no effect on the power supply voltage. Power supply bypass capacitors are effectively removed from the circuit reducing signal propagation times.
