Title: Gear pump
Inventor: KAMOSHITA TOMOYOSHI
IPC: F04C2/18
Filed: 1990-01-18
Abstract: PURPOSE:To restrain reverse flow passage through a clearance between a drive gear/a driven gear and the inner face of a casing by raising pressure on the back side of the drive gear and the driven gear through use of subsidiary gears. CONSTITUTION:A back chamber 13 is formed on the suction side of a casing 1, and a part of liquid sucked from suction ports 2 is fed to this back chamber 13 with subsidiary gears 10, 11 to raise the back pressure of a drive gear 4 and a driven gear 5. Hereby, pressure difference between the suction side and the discharge side is minified, and hence reverse flow is increased not so much even if the clearance between the casing 1 and the gears increases a little. Consequently, it is unnecessary to set the clearance very small, friction loss is decreased, and increasing degree of reverse flow due to progress of wear is also minified.

Filed: 1989-01-17
Abstract: PURPOSE:To unify heat transfer performance in the lengthwide direction of a heat transfer tube by a method wherein two rows or more of heat transfer tubes for promoting the operation of operating liquid in the upper or lower part of a system are arranged and one part of the tubes is used as going tubes while remaining tubes are used as returning tubes. CONSTITUTION:Upper heat transfer tubes are arranged in two rows 3a1, 3a2 and lower heat transfer tubes are arranged in two rows 3c1, 3c2 while one end of the tubes is turned to use the heat transfer tubes in the row 3a1 as a going tube and use the other heat transfer tube in the row 3a2 as a returning tube. The uneven property of performances at the inlet side and the outlet side of the heat transfer tube is improved remarkably and unified heat transfer performance may be shown along the whole length of the heat transfer tube. As a result, the adhering degree of ice upon space cooling operation is equalized in the lengthwise direction of the heat transfer tube, whereby ice 6 may be frozen with the same growing speed along the whole length of the tube. The same thing may be said in space heating operation.

Title: Dictionary retrieving method for character recognizing device
Inventor: NAKAMURA MASAHIRO
IPC: G06K9/48
Filed: 1986-01-20
Abstract: PURPOSE:To shorten dictionary retrieval time by calculating and comparing the total distance between the histogram of an input pattern contour classified by direction codes and a templet with a rejection threshold value as to each point which is given previously, and deciding whether or not a recognition process is advance or not. CONSTITUTION:A microprocessor 10 refers to a dictionary 11 through a dictionary counter 12 and sets a check point in a check point register 13. When this set value becomes equal to the value in the counter 12, a comparator 14 interrupts the processor 10. Then the processor 10 calculates and compares the arithmetic value of the total distance between the histogram based upon an input pattern and the templet with the rejection threshold value. When the total arithmetic value exceeds the threshold value, the processor 10 discards the templete and interrupts subsequent recognition processing, and performs similar processors for a next templete, so the dictionary retrieval time is shortened because of the interruption of unnecessary processes.

Title: Noise rejection circuit
Inventor: KAWAGUCHI TOSHIHARU
IPC: H03G7/00
Filed: 1988-01-21
Abstract: PURPOSE:To reduce noise by obtaining a recording signal through a low pass filter after signal compression processing at recording, passing a reproducing signal to a low pass filter before signal expansion processing at reproduction and applying peak detection to a signal after the low pass filter at all times. CONSTITUTION:The low pass filter 18 acts on a signal after encoding at recording and acts on a signal before decoding at reproduction. Thus, the noise generated from the low pass filter itself is suppressed lower after decoding. Suppose that a minimum gain of the gain control circuit 16 is -50dB, when the noise level of the low pass filter is the same as that of a conventional circuit, the conversion level at the filter output is advantageous by 50dB. Moreover, the input signal to a peak detection circuit 21 is a signal through the low pass filter 18 even at recording and reproduction. Thus, the error of peak detection and to noise invaded in the input is not more disadvantageous than that of the conventional circuit.
