Title: Circuit for detecting synthesis and splitting of light beams
Inventor: YOSHIDA RIYUUZOU
IPC: G02B27/10
Filed: 1983-06-27
Abstract: PURPOSE:To make it possible to synthesize light beams simply, split the synthesized beam, and detect the beams, by synthesizing the outputs from light sources having different wavelengths by chopping, then splitting the result into the light beams having specified wavelengths, and detecting the output of respective light. CONSTITUTION:Light beams are emitted from light sources 4-1, 4-2,... having different wavelengths, guided into the same optical axis by half mirrors H-1, H-2,..., and sybthesized. The light is chopped by a chopper disk 3-1 and emitted to the outside. The emitted light is inputted to a filter F-1 through a beam splitter 5-1 and split into the light beams having various wavelengths. The light beams are applied to an amplifier A-1 through a detector D-1. Meanwhile, a clamping sigal is generated by a timing circuit T by using a chopping signal. The inputted signal is clamped by the clamping signal in the amplifier A-1. DC regeneration is performed, and electric signals corresponding to the intensities of the respective light beams are generated. In this way, the light beams can be split, and the light beams can be detected.

Filed: 1992-05-08
Abstract: PURPOSE:To prevent pressure loss at an end face of an element by forming many passages parallel to a rotary bearing axis between a long liner wound spirally and a corrugated sheet and reducing the width of the liner to be shorter than that of the corrugated sheet. CONSTITUTION:A flat platelike liner 2 is made to adhere to the crests of one surface of a corrugated sheet 3 through adhesive. The liner 2 and the corrugation 3 adhering to one another are wound predetermined number of turns on a periphery of a bearing 4 to form a rotary heat exchanging element. The width B of the liner 2 is formed shorter than that C of the corrugation 3. That is, the corrugated sheet 3 having higher deforming strength than that of the liner 2 protrude from an end face of an element A. Thus, the element A is contained in an element chamber of an entire heat exchanger. Even if an end face is pressurized by a sealing member, drawback such as a narrow passage R due to collapse of the end face is prevented, and hence an increase in pressure loss can be prevented.

Filed: 1995-05-16
Abstract: PURPOSE: To provide an inverter control apparatus by which the waveform distortion of an output to be supplied to a load is suppressed. CONSTITUTION: An inverter control apparatus 10 is constituted of a current command part 11, a difference computing unit 12a, a current controller 13, a low-pass filter 14, a three-phase computing part 15, a PWM modulation part 16 and a current sensor 17. An inverter 21 which converts DC power supplied by a DC power supply 25 into AC power is controlled by the inverter control apparatus 10. The cutoff frequency ff of the low-pass filter 14 is expressed by ff =2π/(NTc). When a command frequency becomes (n) times, the cutoff frequency ff becomes (n) times when a control cycle Tc is set to 1/n. That is to say, when the setting of the control cycle Tc is changed according to the command frequency, the cutoff frequency ff of the low-pass filter 14 can be made easily variable.  As a result, the waveform distortion of an AC current to be supplied to a three-phase AC motor 27 from the inverter 21 can be suppressed.

Abstract: PURPOSE:To prevent the deformation of a heat insulating film by providing ventilating means for allowing outside air to intrude into the through holes of an infrared sensor chip on the surface of a small substrate which is the main body of a bare chip mounting substrate. CONSTITUTION:An infrared sensor chip 6 is bonded to a small substrate 13 with die bonding paste.
