Title: Device for detecting track deviation amount of dt head
Inventor: TOMITA ISAO
IPC: G11B5/588
Filed: 1992-08-28
Abstract: PURPOSE:To detect a track deviation amt. of a DT head at a high speed and with high accuracy. CONSTITUTION:Reproduced signals of A channel and B channel outputted from reproducing heads 52A, 52b in the DT head 5 are supplied to an RF envelope signal detection circuit 7, and RF envelope signals SA1, SB1 superposed with a change component by the track deviation amt. and a wobbling component are detected here. Then, by a tracking error detection circuit 8, a wobbling compont is extracted and a tracking error signal SC is outputted. The tracking error signal SC corresponds to the track deviation amt. of the DT head 5. Thereby, since the track deviation amt. is detected only using the RF envelope signal, a wobbling frequency is possible to be increased, and thus, the track deviation amt. is detected at a high speed and with high accuracy.

Title: Sealing enclosure for outdoor device
Inventor: WATABE SHINJI
IPC: H05K5/06
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a sealing enclosure for outdoor device which has both the advantage of an FRP enclosure having a light weight and an excellent corrosion resistance and a sufficiently high heat radiating property. SOLUTION: A heat radiating window 7 is formed through part of the wall 2a of an FRP enclosure 1 and, at the same time, the window 7 is closed with a heat radiating plate 8 made of an aluminum plate, etc., having high heat conductivity and the peripheral edge section 8a of the plate 8 is buried in the wall 2a. When a heat source 9, such as the power transformer, etc., housed in the enclosure 1 is operated, the heat generated from the source 9 starts to stay in the enclosure 1, but, since the heat is radiated to the outside through the plate 8, the formation of such a high-temperature state that the main body 2 and door 3 of the FRP enclosure 1 are deformed or the heat source 9 or other elements housed in the enclosure 1 are damaged can be prevented.  In addition, since the peripheral edge section 8a of the plate 8 is completely shielded with the FRP constituting the wall 2a of the enclosure 1, the intrusion of rain water, dust, etc., into the enclosure 1 can be prevented.

Title: Laminated ceramic capacitor
Inventor: NAKATANI SHUNSUKE
IPC: H01G4/12
Filed: 1988-09-13
Abstract: PURPOSE:To avoid a deterioration by a method wherein, when outer electrodes are attached to both ends of a laminated dielectric ceramic where inner electrodes are buried to be layerlike, conductive ceramics are laid between both end faces of the ceramic and the outer electrodes in order to restrain especially Sn ion in solder-plated films covering the outer electrodes from creeping. CONSTITUTION:A laminated dielectric ceramic 1 is constituted of the following: a dielectric ceramic 2 composed of a green sheet formed by transforming a material powder in a slurry and by stretching it to be sheetlike; an inner electrode 3 formed after its one face has been coated with a Pd paste and has been baked. The required number of sheets is laminated. Then, outer electrodes 6 covered with solder-plated coatings 7 are connected to alternately protruding end parts of the inner electrodes 3; during this process, conductive ceramics 5 are laid in between. Thereby, a composition material of the solder-plated coatings, especially an Sn ion, is absorbed by the conductive ceramics 5 and does not creep into the side of the inner electrodes 3; accordingly, an electrical characteristic is not deteriorated.

Title: Cassette loading device
Inventor: UEDA MIKIYA
IPC: G11B15/675
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To provide the cassette loading device capable of expecting its reliable operation even in the case of such a heavy tape cassette as of a high-definition system in a vertical installment cassette type magnetic recording and reproducing device. SOLUTION: A moving member 10 is pressed downward against energizing force of a 2nd energizing means 5b via a detecting plate 6 by a tape cassette, loading of the tape cassette is started under the state of nonoperation of energizing force of the energizing means 5b upon the detecting plate 6 after the moving member 10 is engaged with a lock means 12 as shown in the state of (b) from (a). Therefore, the tape cassette loading is not started up before the tape cassette loaded into an inserting hole is handled to be pressed downward because the tape cassette is energized upward by energizing force of the energizing means 5b.  Consequently, by selecting energizing force of the energizing means 5b to be as energizing force for lifting enough a heavy tape cassette like the high-definition system tape cassette, the reliable operation can be expected even in the case of the high-definition system tape cassette.

Title: Thermomagnetic recorder
Inventor: TAKAHASHI YUICHI
IPC: G03G19/00
Filed: 1985-10-16
Abstract: PURPOSE:To prevent omission in a developed image even in case of quick write by making the magnetization direction of a magnetizer and that of a thermomagnetic recording means orthogonal to the advance direction of a thermomagnetic recording material and making said magnetization directions opposite to each other. CONSTITUTION:The magnetization direction of an arrow A of a permanent magnet constituting a magnetizer 4 and that of an arrow B of a magnetic latent image forming permanent magnet 9 are orthogonal to the advance direction of an arrow C of a recording material 3. That is, the magnetizer 4 and the magnetic latent image forming permanent magnet 9 are arranged orthogonally to the advance direction of the recording material 3 and N and S poles are arranged in the breadthwise direction of the recording material 3 thereby to make magnetization directions orthogonal to each other. Connection between magnetic field inverting areas in the main scanning direction (the direction orthogonal to the advance direction of the recording material) is prevented easily by selecting properly the arrangement density of heating resistors 7 of a heating head array, the applied energy, the heat application time, etc., and the connection between magnetic fields in the subscanning direction (the advance direction of the recording material) does not occur at all. Thus, omission based on connection between magnetic fields is not generated at all.

Abstract: PURPOSE:To obtain returned air of predetermined temperature and humidity by refluxing part of the returned air to a low temperature side of a heat exchanger, and bringing said part into contact with water without interruption when said part is heat-exchanged with high temperature side dry air directing said part of the returned air so as to form an counterflow with respect to the dry air to lower the temperature of the dried air to the neighbourhood of wet-bulb temperature, and further evacuating said part of the returned air keeping a sufficient temperature difference from the high temperature side. CONSTITUTION:Received air 1 is sent to an air dehumidification tower 3 by a fan 2. A concentrated LiBr absorption fluid 7 is refluxed from the top part upon the received air rising in the inside, and makes contact with the rising air during the fluid 7 lowering. Dry air is cooled to about predetermined temperature 20 deg.C in an air heat exchanger 12. The inside of the air heat exchanger is divided into a high temperature side 12b and a low temperature part 12c through a partition, between which parts heat transfer is effected through a heat transfer mechanism 13 owing to a temperature difference. The dry air is cooled upon its passing from the low to upper, and after reaching 20 deg.C for example it reaches an adiabatic water evaporator 14. Herein, the air makes contact with a proper amount of poured water 15 at ordinary temperature supplied through a spray nozzle 16, whereby adiabatic cooling and a humidity increase of the air are simultaneously effected for obtaining predetermined temperature and humidity.

Title: Excitation method for piezoelectric element and control method for actuator
Inventor: MATSUMOTO EISAKU
IPC: H02N2/00
Filed: 1990-09-01
Abstract: PURPOSE:To get excitation method for a piezoelectric element by which the control in vibrational direction of ultrasonic elliptic vibration is easy by changing the direction of the application of the voltage applied to an electrode thereby controlling the direction of the ultrasonic elliptic vibration of the piezoelectric element. CONSTITUTION:When voltage is applied to the piezoelectric element 14 of an electrostrictive revolver type ultrasonic motor, the part where voltage is applied in the same direction as the direction of polarization is deformed in the peripheral direction of the piezoelectric element 14, and the part where voltage is applied in the opposite direction to the direction of polarization is deformed in the direction of shrinkage. Accordingly, when AC voltage is applied to electrodes 121-124, the piezoelectric element 14 performs ultrasonic elliptic vibration. Moreover, for a rotor 4, the part against which the rotor 4 is pressed vibrates in the peripheral direction, besides it is dragged in the vibrational direction of the part contiguous to that part, so the rotor 4 rotates receiving the force by these vibration continuously.
