Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To provide a surface treatment method for a heat transfer tube, so that a good hydrophilic property can be obtained. SOLUTION: A hydrophilic film forming agent, which has a resin and silica as main ingredients, and which has the solids weight ratio of the resin to silica (resin/silica) of 0.03 to 0.5, is applied and baked to the surface of the heat transfer tube, so that the hydrophilic film is formed on the surface of the heat transfer tube in a thickness of 0.1 to 10 μm. The formed hydrophilic film is flushed. The flushing is preferred to be done in a method in which the heat transfer tube is soaked in water for 10 minutes or longer, or which 3 liters per 1 m<2> or more of water is poured on the hydrophilic film formed surface of the heat transfer tube to flush the hydrophilic film which is formed on the surface of the heat transfer tube.  Therefore, the pollutant which is adsorbed on the hydrophilic film of the heat transfer tube surface is eliminated by being flushed, so that the heat transfer tube is excellent in hydrophilic properties. Therefore, the heat exchange properties of the absorption refrigerating machine using the treated heat transfer tube is improved.

Abstract: PURPOSE:To decrease the magnetic powder sticking to the front surface of the magnetic head with high efficiency by providing a vibration imparting means for ultrasonically vibrating the front surface along the traveling direction of a magnetic recording medium. CONSTITUTION:In a magnetic head 32, ultrasonic vibrations are generated in an ultrasonic vibrator transducer 34 by impressing an AC current to the transducer 34 provided on the magnetic head 32 while a magnetic tape 28 travels. The magnetic tape 28 slides at a prescribed speed on the front surface 18 of the head 32 and recording is executed by imparting magnetic fields to the tape 28 passing a magnetic gap. Reproducing is executed by taking out the magnetic fields generated by the passage of the tape 28. The ultrasonic vibrations for resonating the head 32 by generating the ultrasonic vibrations in the transducer 34 are so applied along an arrow mark alpha in the traveling direction of the tape 28 that the front surface 18 of the head 32 vibrates elliptically. As a result, the magnetic powder sticking to the front surface 18 of the head 32 is decreased with the high efficiency.

Title: Device for detecting leakage from piping
Inventor: UEDA YASUKIYO
IPC: G01M3/28
Filed: 1994-08-04
Abstract: PURPOSE:To improve the reliability of the automatic leakage judgement of a device for detecting leakage from piping by storing the minimum value of measured gas flow rate values at every prescribed period and judging the increasing tendency of the minimum flow rate value. CONSTITUTION:A piping leakage judging means 8 incorporating a minimum flow rate value storing means 13 which stores the minimum value of gas flow rate values measured by means of a total gas flow rate measuring means 7 at every prescribed period under the control of a first timer means 12 and an increase judging means 15 which judges the increase of the minimum flow rate value is provided. For example, the measuring means 7 measures the total flow rate of a gas supplied to a group dwelling house and the storing means 13 stores the minimum value of the measured flow rate values as the value of a specific resident of the dwelling house together with the measurement error. When no gas leakage occurs from piping, the judged result of the judging means 15 becomes zero including the error, because the minimum value does not change. When leakage occurs, however, the judged result of the means 15 becomes a positive value which is equal to the amount of leakage. Therefore, the leakage can be detected.

Title: Low voltage switching capacitance circuit using switching operational amplifier with maximum voltage swing
Inventor: CASTELLO RINALDO
IPC: H03H19/00
Filed: 1995-06-26
Abstract: PURPOSE: To eliminate the loss of a charge and to hold a dynamic characteristic by stitching the output of the input switched operational amplifier structure of a switched capacitance circuit to supply voltage. CONSTITUTION: The output of the input switched operational amplifier structure of the switched capacitance circuit is switched to supply voltage Vdd instead of making it to a ground value. It is realized by using a private integrated P-channel switch in a substrate connected to supply voltage Vdd and what is called body effect is removed. Thus, the output node of the input operational amplifier A1 does not take negative voltage during an operation when the switched operational amplifier is turned off. For subtracting Vdd/2 voltage instead of adding them, a clock phase for driving two switches S2 and S3 connecting a bias capacitor Cdc to the supply node and ground is exchanged. Thus, the arbitrary loss through respective substrates can be prevented.

Title: Timer device
Inventor: NISHIMURA KIYOSHI
IPC: H03K17/28
Filed: 1982-10-19
Abstract: PURPOSE:To obtain an accurate timer output despite the disturance generated to the time interval of a trigger pulse by providing a hysteresis function to a voltage comparator and controlling a switching control circuit with the output of said hysteresis function. CONSTITUTION:When the terminal voltage of a capacitor 50 exceeds the upper limit level of reference voltage that is set to a voltage comparator 8 by voltage dividing circuits of resistances 74, 76 and 78, the output of the circuit 8 is set at a low level and applied to the base of a transistor TR80 of a hysteresis circuit 70 via an NAND gate 82. Thus a TR80 is turned on. As a result, the lower limit reference volage level is set to a terminal (+) of the circuit 8 by the resistances 74 and 76. The output of the circuit 8 is kept at a low level for a period during which the terminal voltage of the capacitor 50 is set lower than the lower limit reference voltage level. At the same time, an inhibiting circuit 72 acts on an FF12 of a switching control circuit 2 in response to the output of an NAND gate 82. In other words, the output of the gate 82 is applied to an AND gate 84 to reset the FF12. Thus the pass of a trigger pulse inhibited until the capacitor 50 is set at a level lower than the lower limit reference value.

Title: Automatic electronically tuned receiver
Inventor: GOTO KOJI
IPC: H04B1/18
Filed: 1989-07-17
Abstract: PURPOSE:To execute the tuning by a small number of button operations and in a short time, by making a stop at a weak signal broadcast frequency on the first scan, passing it on the second scan, and releasing limit for stop on the third time and thereafter. CONSTITUTION:By a CPU 6, a broadcast local frequency of the front end is tuned so as to fetch successively a desired frequency. A signal strength of an output of an RF stage 3 is detected and a weak signal broadcast frequency fetched temporarily on the first search is stored by the CPU 6. Allowing the tuner to pass through it on the second search, and setting a limit for stop on weak signal frequency thereafter, the tuner releases this limit on the third search and thereafter. In such a way, a temporary stop for an unnecessary weak signal point is eliminated for less button operations resulting in an automatic tuning mode for strong signal frequency in a short time.
