Title: Scroll type hydraulic machine
Inventor: YAMAMOTO SAKUE
IPC: F04C18/02
Filed: 1987-03-31
Abstract: PURPOSE:To seal a gap in the radial direction automatically so as to enhance the efficiency of the machine in the caption by providing the 1st bearing member supporting a driven scroll rotationally and the 2nd bearing member supporting the 1st bearing member rotationally. CONSTITUTION:A driven scroll 2 rotates round its center O2, while a scroll shaft 5 is fitted into the bearing portion 8 of a bush 7 so as to be supported thereby rotationally. The compression on the driven scroll 2 or a load F1 due to pump operation is transmitted via the bearing portion 8 to the bush 7. The rotation of the bush 7 due to the load F1 and the increase in the distance between the center O1 and the center O2 will cause a radial gap between the driven scroll 2 and the radial seal portion of a driving scroll to decrease. Hence the efficiency of a hydraulic machine can be enhanced.

Title: Method for correcting colorimetric value
Inventor: SHIGEMORI YOSHIHIRO
IPC: G01J3/46
Filed: 1995-03-13
Abstract: PURPOSE: To measure a monochrome or a mixed color with accurate and simple measurement operation by measuring a spectral reflection factor of a pigmented sample at an arbitrary temperature and numerically correcting the actually measured value with the difference between an absorption coefficient and a scattering coefficient for each wavelength obtained from the spectral reflection factor which is measured in advance as a correction coefficient. CONSTITUTION: With the difference between an absorption coefficient and a scattering coefficient for each wavelength obtained from spectral reflection/transmittance which are measured under different temperature conditions at least at two points for a base dye pigment in advance as a correction coefficient, the influence of the measurement error due to temperature change can be effectively eliminated by correcting the measurement value of a sample to be measured being actually measured at an arbitrary temperature to a colorimetric value at a standard temperature using the correction coefficient. Further, not only the colorimetric value of a monochrome but also that of a mixed color can be easily corrected.  In a practical application, a correction coefficient is handled as the database of a base dye pigment and the blend ratio of a mixed color consisting of several types is inputted, thus simulating spectral reflection/transmittance to an arbitrary temperature.

Filed: 1993-04-07
Abstract: PURPOSE:To eliminate the need for a changeover switch and a standby power amplifier element for the power amplifier and to obtain the power amplifier without causing using deterioration in performance attended with a fault of a changeover switch. CONSTITUTION:A communication signal received from input terminals 13 and separated to each channel is equally divided into (N+M) at a 3 dB hybrid. The divided communication signal is amplified up to 1/N of a power P desired to be outputted by optional N-sets of power amplifier elements 15 among (N+M) sets of the elements 15, and the resulting powers are synthesized by a power synthesizer 16 and outputs corresponding to the input terminals 13 of the power divider 14 are obtained at multi-port output terminals 11. Only N-sets of the power amplifier elements 15 are started and the remaining M-sets are stopped. Thus, a power amplifier element 15 in the stop state is properly started when the active power amplifier element 15 is faulty. An isolation characteristic change or the like attended with a change in the electric length is not caused when the standby power amplifier element 15 is selected and the amplification with high reliability is attained.
