Title: Method and apparatus for measuring thickness of layer of molten slag
Inventor: MIYAHARA SHINOBU
IPC: B22D11/16
Filed: 1979-04-06
Abstract: PURPOSE: To accurately measure the thickness of a slag layer on a molten metal by using a measuring apparatus consisting of a one-end-closed cylindrical body, and a molten slag detection electrode, a fine differential pressure gauge and a thermocouple which are provided in the mentioned cylindrical body.  
     CONSTITUTION: An insulating tube 7 to which a molten slag detection electrode 2 is connected is provided in a one-end-closed cylindrical body 1. The electrode 2 is connected to an electrode contact 11 of an insulating body 10 provided on a junction body which is joined to the cylindrical body 1 via a packing 5. The junction body is further joined to a base cylinder 12 which is provided therein with a fine differential pressure gauge 3 and a thermocouple 4. All of the electrode 2, fine differential pressure gauge 3 and thermocouple 4 are connected to an arithmetic processor 14 to which a display unit 15 is connected. When this measuring apparatus is inserted into a layer A of molten slag formed on a layer B of molten metal, the electrode 2 comes into contact with the layer A and an electric current starts flowing. When the apparatus is further inserted so that the electrode 2 reaches an interface between the layers A, B, discontinuous changes occur in the electric current. These changes in the electric cuttent as well as the pressure and temperature are continuously measured. Thus, the thickness of the slag can be accurately determined.

Title: Switching power supply device
Inventor: TAKEDA KATSUNOBU
IPC: H02M3/155
Filed: 1979-04-06
Abstract: PURPOSE:To reduce the loss in a switching transistor, by using a saturable reactor to decrease a heavy current which flows within the inverse recovery time of a feedback diode. CONSTITUTION:When a switching transistor 4 is driven, a current 9 flows. A heavy current, which flows within the inverse recovery time of a feedback diode 5, is limited by a saturable reactor 12 so that the level of the current is suppressed. Within said time, a voltage is applied to a reactor 12 and the voltage across the collector and emitter of the switching transistor 4 falls. As a result, the loss in the switching transistor decreases.

Title: Discrete cosine conversion method
Inventor: BAABARA AN HOORU
IPC: H04N7/30
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To improve the coding speed by conducting field discrete cosine transformation when a field variance is smaller than a frame variance and conducting frame discrete cosine transformation when the frame variance is smaller than the field variance. SOLUTION: A processor 11 is used for discrete cosine transformation coding in the digital video coder processor. A coder calculates a total difference between adjacent lines of a frame structure and then calculates a total difference between adjacent lines of a field structure. When a field total variance is smaller, a field discrete cosine transformation type is selected. When a frame total variance is smaller, a frame discrete cosine transformation type is selected. The frame variance is calculated by the total sum of absolute differences between adjacent lines in a frame structure. The field variance is calculated by fields 1, 2, and the field 1 is the sum of absolute differences between adjacent odd number lines in the frame structure and the field 2 is the sum of absolute differences between adjacent even number lines.

Title: Sensitivity correcting equipment for label sensor
Inventor: IZUMIDA KOJI
IPC: B65H7/14
Filed: 1988-02-24
Abstract: PURPOSE:To enable adjustment so that the voltage for the detecting signal, which is put in the label detecting part, can maintain an appropriate detecting level even when there are differences in the characteristics of a photo-sensor, by providing a voltage adjusting main, which can alternate the output voltage, at the output port of the photo-sensor. CONSTITUTION:An initial correcting signal is put out from correcting signal output ports 151-153 to transistors Tr1-Tr2, and all the voltage adjusting circuits 141-143 are closed. Then the combined resistance for a sensitivity correcting equipment 14 including a resistor 11 becomes minimum, and the detecting signal to be put out becomes a minimum value. For example, if resistors R1, R2, R3, which are connected in parallel, have been set at 1OMEGA, 2OMEGA, 3OMEGA, respectively, depending on the combination, seven types of combined resistances can be obtained. Thus, the voltage of the detecting signal can be corrected in seven steps. Therefore, by providing the voltage adjusting device, even when there is a difference in the characteristics of a photo-sensor due to manufacturing error on the optical element in use, the adjustment to make the input voltage for the level detecting part maintain an appropriate detecting level is enabled.

The optical card C is moved from the insertion position to a recording/reproducing position where the loading operation of the optical card C is ended. When the stage 10 moves to a prescribed amount, card guide members 3a and 3b and the guide members 11a and 11b of the stage 10 attain the state that the positions in a horizontal direction do not coincide. The transporting path closing means 11c closes the transporting path. Recording/ reproducing are executed by controlling an optical head. The guide member 11b of the stage 10 closes the transporting path to the thickness of the optical card with respect to the thickness direction or above, by which the insertion of the second optical card is prevented.
