Inventor: OOSHIMA KAZUO
IPC: G01F23/22
Filed: 1979-03-30
Abstract: PURPOSE: To increase the accuracy measurement and the safety, by fixing the temperature sensing resistor vertical to the wall in contact with mold molten steel and measuring the molten steel level from the resistance value of this resistor.  
     CONSTITUTION: The nozzle 2 is inserted in the cavity of the mold 1 and the molten steel 3 is cast from the nozzle 2. The mold 1 is made of steel with good theremal conductivity, and the internal is cooled with the cooling water 4 to cool the molten metal 3. the molten steel level detector 7 is built in vertically on the other side to the side in contact with the molten steel 3 of the mold 1, and molten steel level can be obtained by measuring the resistance value of the platinum wire 8 constituting the detection line 7.

Abstract: PURPOSE:To control an operation terminal equipment depending on a physical position of the operation terminal equipment or the like by receiving an identification number generated from a communication terminal equipment connection connector and collating an identification number, a communication terminal equipment name and its physical position based on a database. CONSTITUTION:A specific ID(identification) number are registered respectively to connectors C1, C2... as node connection ports to a network and a cross reference list between the ID number and its physical position is stored in advance in a database device DB. The cross reference between the ID number of each connector and the node name is generated in the database device DB by the registration from each node. When the node name is given to the database device DB, the ID number of the connector is read from the node name based on the cross reference list and its physical position is read from the ID number. Thus, even when a portable or movable operation terminal equipment or installation device is connected to the network, the physical position, not the device number is designated and controlled.

Title: Signal recording system
Inventor: KITAMURA SADAFUMI
IPC: H04N5/92
Filed: 1980-03-25
Abstract: PURPOSE: To raise a reproduction sensitivity in a long wavelength area, by utilizing a characteristic generated in case when two signals have been superposed and recorded by use of a tape of thin magnetic layer such as an evaporated ME tape.  
     CONSTITUTION: In the optimum recording by using an ME tape, if the mixing ratio of two signals is set to a value by which a reproduction level of a luminance signal FM wave fY starts to fall, the set points of two points of G and H is obtained. When the difference of both these set points is compared, at first, an fY reproduction level is all the same. Secondly, a cross modulation level has scarcely a difference at the point Y. Thirdly, as for a reproduction level of a low pass conversion color signal wave fC, a difference of X is generated, and the point H is higher. When the mixing ratio is set to the point H by said characteristics, the reproduction f c  level is elevated. Accordingly, when a signal recording condition is set in this way, an output in the long wavelength area can be raised and the reproduction sensitivity can be elevated.

Title: Semiconductor logic circuit
Inventor: ASANO MICHIO
IPC: H03K19/017
Filed: 1984-03-02
Abstract: PURPOSE:To decrease the number of circuit stages of signal path and the entire circuit number, to reduce power consumption and to realize an ultrahigh speed integrated circuit by adding a source follower circuit comprising MESFET to a DCFL circuit and specifying the threshold voltage of the MESFET so that the operating margin is not decreased even with Wired OR at the source follower. CONSTITUTION:In order to decrease the increase in a delay time due to a load capacitance, it has only to inrease the gate width of the MESFETs T15, T16 for source follower driving the load, and the gate width of the MESFETs T11-T14 can be small. Thus, although the element number is more than that of a DCFL circuit, the delay time of the load is decreased with the same chip size. Since Wired OR is applied, the same logic is realized with fewer number of circuits. Since the increase in the delay time due to load capacitance is small and Wired OR is applied in this way, the entire circuit number and circuit stage number of signal paths are reduced, allowing to realize an ultrahigh speed integrated circuit.

CONSTITUTION:An outside pipe 20 is heated at a prescribed temperature to increase  the diameter of the pipe, and an inside pipe 21 is cooled from a natural temperature  by cold water to reduce the diameter of the pipe, and these pipes are superposed relatively with the difference in diameter and are fitted, and the front end of the inside  pipe 21 is fixed to a seal clamp 11 of a stand 4. A cylinder 7' is operated to move a  sleeve piston backward through a cross head 14 and a pressing spring 19, and the rear  end of the inside pipe 21 is fixed to a seal clamp 11', and the cylinder is operated to  set the inside pipe 21 so that an intial pressing-in force of a set magnitude in the axial  direction is given to the inside pipe 21 through the pressing spring 19. Then, a valve 5'  is closed, and a valve 5 is opened, and water is charged into the inside pipe 21 through  a conduit 6 and a water charging hole 3 to fill up water in the inside pipe 21. Next,  the valve 5 is closed, and a plunger 8 is press-advanced by a cylinder 7 to apply a pipe  expanding force to the inside pipe 21. At this time, though the inside pipe 21 is contracted in the axial direction because of pipe expansion, the inside pipe 21 is pressed  into the outside pipe by the pressing-in force of the pressing spring 19.
