Title: Ink jet recording head
Inventor: MORIYAMA JIRO
IPC: B41J2/135
Filed: 1987-09-30
Abstract: PURPOSE:To reduce power consumption of a device, improve printing quality and shorten time required for printing by making the same size of a cross-section area which crosses directly an ink flow direction of a liquid passage near a heat-generating part as that of an orifice side. CONSTITUTION:The cross-section area of a liquid passage which crosses directly an ink flow direction near a heat-generating part 5 is formed to match that of an orifice 1 side. When this taper angle is alpha deg.=30 deg., an angle formed by two lines which cross directly the wall surface from the center C of the heat- generating part 5 is beta deg.=150 deg.. When heat generation starts, bubbles are directed from the center C of the heat-generating part to all the directions under uniform pressure. The ratio of bubble energy which moves the ink back and forth is Ef:Eb=360-beta:beta=7:5. Therefore, the ratio R of contribution to ink discharge is R=Ef/(Ef+Eb)approx.=0.85. Consequently, the energy efficiency is improved by about 17% compared to a conventional device. Further, since the lengths of the ink flow passages on the effective orifice side and the ink supply side are equal, it is made possible to shorten the time required for ink supply to the flow passage 2 after ink discharge.

Filed: 1990-09-17
Abstract: PURPOSE:To intuitively, sensitively, and easily perform a performance operation and musical tone control by generating a musical tone according to a parameter automatically generated corresponding to voice vocalized from a player. CONSTITUTION:When the voice from a microphone is inputted after being converted to an audio signal, the level envelope of a frequency component signal analyzed by a frequency spectrum analyzer 7 is extracted from the frequency component signal by an envelope detector 8.

Filed: 1994-10-13
Abstract: PURPOSE: To simplify a calibrating/testing work when the actual flow rate of a Karman's vortex flowmeter is calibrated, by obtaining a correct, corrected flow rate even if the flow rate of a calibration fluid is not matched to a value of a calibration point. CONSTITUTION: Arm EPROM 9 is provided at a transmitting part 2 of the Karman's vortex flowmeter, which writes and holds values of the flow fate and the correction amount of the flow rate at a flow rate calibration point measured by a reference flowmeter to calibrate/test the actual flow rate. When a linear correction flag indicates to execute a correction operation, namely, when the flag indicates a normal measurement, a measured value of the flow rate obtained by processing an output pulse of a flow rate detection part 1 is linearly interpolated with the use of values of the flow rate and correction amount held in the EPROM 9 thereby to operate and output tone correction amount.  If the linear correction flag indicates not to execute the correction operation, that is, when the actual flow rate is to be calibrated/tested, the measured value obtained at the frequency/flow rate operation process is output as it is thereby to obtain the flow rate and correction amount at the flow rate correction point to be written in the EPROM 9.

IPC: H04S1/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To allow a data processor used in common for other processing to process stereo sound data so as to distribute a processing load therefor. SOLUTION: A data processor 20 demodulates stereo sound data and stores the demodulated data to buffer means 4, 5.

Title: Operating device of vehicle air conditioner
Inventor: ISHIGURO KAZUYOSHI
IPC: B60H1/00
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a setting device by providing a deviation compensating mechanism for absorbing force in the direction intersecting a rotary shaft caused by a deviation existing in the rotary shaft center of the setting device or in the center of an opening. SOLUTION: When an adapter 60 is attached from the back surface of a cover 18, the sliding shaft 82 of a knob shaft 80 and the inserting port 66 of the adapter 60 are positioned and fitted so as to coincide with each other in shape. Since the length of the inserting port 66 in its longitudinal direction is longer than the length of the sliding shaft 82 in its longitudinal direction, the sliding shaft 82 is slid within a specified range only in its longitudinal direction against the adapter 60. When the cover 18 is attached to a main body in this condition, the sliding shaft 62 of the adapter 60 is caused to fit in a slit of the rotary shaft 52 of a variable resistor 50. Since the width of the sliding shaft and the width of the slit are coincident with each other considering specified intersection, the adapter 60 is moved in the direction of the slit.  Thus, no excess force caused by shifting is applied to the rotary shaft 52 of the variable resistor 50.
