Title: Internal member of heat exchanger
Inventor: SUTEIIBUN JIYON HIYUUZU
IPC: F28F9/24
Filed: 1993-05-10
Abstract: PURPOSE: To reduce abrasion in a heat exchanger by employing internal members including a thermoplastic material of polyetheretherketone that has a low abrasion coefficient. CONSTITUTION: An aluminum alloy thin-walled tube 3 passes through the holes of baffle plates 5 and 6. The baffle plate 5 is smaller in diameter than the inner periphery of a shell 1 and is made of aluminum alloy or PEEK (polyetheretherketone). The other baffle plate 6 is larger in diameter than the baffle plate 5 and is made of PEEK. A distance tube 7 is also made of PEEK. When a heat exchanger is vibrated in use and the thin-walled tube 3 is relatively displaced with respect to the baffle plates 5 and 6, the degree of abrasion is reduced because of the low abrasion and friction characteristics of PEEK.  In addition, since PEEK is larger in linear thermal expansion coefficient than aluminum alloy, at a high operating temperature, the tube 7 is pressed against an end plate 2 and the baffle plate 6 is fixed inside the shell 1 by a shrink fit, so that the heat exchanger is increased in rigidity and reduced in abrasion.

Abstract: PURPOSE:To obtain a method and a device which can easily diagnose the degree of deterioration of an electric circuit for accurately predicting the failure timing of the electric circuit and a method and a device for detecting an abnormal waveform which are suitable for them. CONSTITUTION:A threshold voltage setting circuit 203 sets two threshold voltages Va and Vb between the maximum and minimum levels of the output of a right arm RA of an inverter in an uninterruptible power supply device. A comparator 206 compares the number of times when the output level of the right arm RA passes the threshold value voltage Va with a reference count. A comparator 207 compares the number of times when the output level of the right arm Ra passes the threshold voltage Va with the number of times when it passes the threshold voltage Vb. Comparator 214 and 215 compare the time width and the reference time width when the output level of the right arm RA passes between threshold values. The outputs of the comparators 206, 207, 214, and 215 are taken out as abnormal waveform detection outputs and are counted by a counter 217.

Title: Base current canceling circuit
Inventor: YOKOGAWA FUMIHIKO
IPC: H03F1/56
Filed: 1982-06-24
Abstract: PURPOSE:To cancel a base current and to reduce an input offset current by inserting a diode in the path of the base current of the same conduction type 2nd transistor (TR) as the 1st TR whose base current is to be canceled, and forming the 3rd current mirror circuit. CONSTITUTION:The current amplification factor of a TRQ1 consituting an input-stage differential amplifier with a TRQ2 is hFE. When the lead-in current of the differential amplifier is IO, the base current of the TRQ1 is IO/hFE. A TRQ3 is matched with the TRQ1 and their current amplification factors hFE are equalized to each other. Then the TRQ3 has a base current I0hFE, which flows through a diode D1. The diode D1 and a TRQ4 constitute a current mirror circuit and the TRQ4 has a collector current IO/hFE. Therefore, the collector current of the TRQ4 and the base current of the TRQ1 become equal to each other and the base current of the TRQ1 does not flow in the input stage, but flows to the ground through the TRQ4, so that no evil influence upon other circuits is exerted.

Title: Fluid vibration type flow meter
Inventor: IKEDA HIDEAKI
IPC: G01F1/20
Filed: 1991-04-12
Abstract: PURPOSE:To enable a measurement accuracy at a small-flow region to be improved by setting dimensions of a width of a jet nozzle and a width and a thickness of a column-shaped target so that they satisfy a specific relationship. CONSTITUTION:A width (t) of a jet nozzle 12 and a width (a) and a thickness (b) of a column-shaped target are set so that they satisfy an expression 1.0<=(a)<(t)<=1.4 and (b)/(a)<=0.6. A jet flow which is jetted out of the nozzle 12 is deflected in either direction by a target 13 and advances toward a side surface 15a. An eddy 8 is generated at a downstream side of the target 13 and a circulation flow 9 is generated around the target 13. Since the circulation flow 9 is generated in a direction for enabling a jet flow to be deflected to an opposite side, the jet flow is switched so that it advances toward a wall surface 15b. This switching is generated alternately and fluid vibration which a frequency which is proportional to the flow is generated. A signal which is outputted from a pressure or a flow-rate sensor is processed by a measuring equipment 19, thus enabling the flow to be measured. This flow meter achieves a highly accurate measurement since a width (t) of the jet nozzle 12 and the width (a) and the thickness (b) of the column-shaped target 13 satisfy the above expression so that the eddy 8 is generated stably even at a small flow region.

Title: Method and device for removing afterimage of image signal and rapidly inputting the same signal
Inventor: TANIMOTO TETSUZO
IPC: H04N5/335
Filed: 1990-04-27
Abstract: PURPOSE:To make it possible to input an image at a high speed by removing an afterimage at the time of no inputting an image, and at the time of inputting the image, instantaneously receiving the image and then immediately outputting an image signal. CONSTITUTION:The image processor utilizing a CCD image sensor 1 inputs an image signal and then executes the arithmetic processing of the image signal by an inherent flow. Thus, an afterimage can be removed without requiring useless time by shielding a photodetecting face by an optical control means 3 while utilizing the above time and scanning an image at the maximum speed allowed of the image sensor 1. At the time of inputting the input signal, the photodetecting face is instantaneously turned to a photodetecting state by the means 3 and then a transfer clock (scanning start command) is forcedly applied to the sensor 1. Thereby, the image signal can be read out within the time of one scanning. Consequently, the afterimage can be removed without requiring useless time and the image signal can be rapidly inputted.
