Title: Method and apparatus for measuring level and temperature of molten metal
Inventor: SADACHIKA MASARU
IPC: G01J5/02
Filed: 1987-02-10
Abstract: PURPOSE:To simultaneously measure the level and temp. of a molten metal, by a method wherein a gas sending pipe allowing inert gas to flow out from the opening part at the lower end thereof is allowed to fall and penetrate in the molten metal having slag floating on the upper surface thereof. CONSTITUTION:When a gas sending pipe 5 is allowed to fall while inert gas is allowed to flow in the pipe 5 under a constant flow rate condition, the opening part at the lower end of the pipe 5 reaches the upper surface of slag S and enters the slag S while the slag S pushed aside by the pressure of the gas and further penetrates in the molten metal M below the slag S. In this process, since the inert gas comes to change in back pressure of course in the atmosphere, the slag and the molten metal, the change in this back pressure is read by a back pressure detector 7. The position of the leading end of the pipe 5 is confirmed by a leading end detector 8 and said position is set as a start point to calculate the distance falling on and after and both of the position and the distance are combined to measure the height of the surface of the molten metal, that is, the level thereof. When the temp. of the molten metal is measured by the infrared thermometer 6 provided to the upper end of the pipe 5 at the point of time when it is confirmed that the leading end of the pipe 5 sufficiently enters the molten metal M while the change in back pressure is observed, the temp. of the molten metal is accurately measured without receiving the effect from the slag S.

Title: Method and apparatus for detecting intermission of continuously transferred articles
Inventor: MIYAMOTO NORITO
IPC: G01V8/10
Filed: 1990-02-13
Abstract: PURPOSE:To certainly detect the intermission of transferred articles in an early stage by setting one area in the flow of the articles within a screen and comparing the change of the quantity-of-light signal extracted from the area with a reference value. CONSTITUTION:When the images of the articles continuously transferred by a belt conveyor 1 are taken 3 by a camera and an image signal V is sent to a signal processing circuit 4, the circuit 4 sets an area at the arbitrary position in a screen to display a marker (a). This area is pref. set so that the quantity-of-light signal A in the area being the output signal of the circuit 4 largely changes when the articles 2 are normally transferred. The signal A in the area extracted by the circuit 4 becomes a quantity-of-light change signal D by operating 6 the change to a time by a differentiation circuit. Subsequently, the absolute value of the signal D is compared with a preset reference value Dt by a comparator 7 and, when the absolute value is larger than the reference value Dt, an article passage signal M is outputted to a timer 8. The timer 8 restarts by the signal M but, when there is no input of the signal M and a set time T arrives, an alarm signal AL informing the intermission of the articles 2 is emitted.

Title: Speed controller for automobile
Inventor: HARA KIYOSHI
IPC: G05D13/62
Filed: 1983-02-23
Abstract: PURPOSE:To secure the safety of an automatic run by limiting a running speed when signals corresponding to the operation speed of a steering operation device and the running speed are in specific relation. CONSTITUTION:An angle voltage outputted from a position detector varies with the operation speed of the steering operation device. This angle voltage is supplied to the analog input terminal of a digital computer 3 through an input circuit 3. Further, a signal voltage corresponding to the running speed of an automobile is applied to the interruption input terminal of the computer 4 through an input circuit 6. Then, when the operation speed of the steering operation device is within the permissible range of a reference speed, the automobile is held from running at a target speed. A de-energization signal is generated at the output terminal when the level attains to an energization level to open a normally open solenoid valve 12. Then, an electromechanical operating mechanism 11 loses the capability of controlling a speed control element 10. Then, the element 10 is returned to a speed reduction side and the automobile is released from a constant-speed run to perform speed reduction, i.e. limit the speed.

Title: Production of optical fiber
Inventor: NAKAHARA MOTOHIRO
IPC: C03B37/027
Filed: 1981-03-05
Abstract: PURPOSE:A glass of a lower softening point than that of the clad of the parent material is arranged outermost and the parent material is drawn with a tension of more than a specific value to give the resultant fiber a compression stress, thus producing optically fiber with high reliability, because of its freeness from static fatigue. CONSTITUTION:The core 6 with a square distribution of refraction index is composed of GeO2-SiO2 glass and the clad 7 of SiO2. The parent material is inserted into a glass pipe of low melting point and they are fused by heating from one end to prepare P2O5 dope SiO2 glass jacket 8. The resultant parent material is heated and drawn with a tension of more than 0.05% elongation, when the tension is calculated as an elongation of the optical fiber, then immediately coated with a silicone resin 9 to give the objective optical fiber. This drawing makes the mechanical strain of the fiber larger than the static load, thus causing no static fatigue.

Title: Electric lock controller
Inventor: SATO TAKEHIKO
IPC: E05B41/00
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To control an electric lock by applying the ready-made electric lock as it is without requiring no processing circuit for complicated data and completely removing wirings between an electric lock controller and the electric lock. SOLUTION: An electric conduction unit 5 separated into a door-side unit 11 and a door-frame side unit 12 is disposed between an electric lock controller 4 and an electric lock 1. A coil 20 for an oscillator 17 in the unit 12 transmits a control signal at a high level or a low level in response to the presence of the control of the electric lock 1. The control signal is received by a coil 13 in the unit 11 electromagnetically coupled with the coil 20. When the control signal at a specified level or more is decided by a level decision circuit 14, a driving signal is output to an actuator 6. A monitor signal indicating the state of locking or release is transmitted from a coil 15 through a lock monitor switch 7 under a closed state by the control signal received by the coil 13.  The monitor signal is received to a coil 22 for the unit 12, and changed into DCs and input to the electric lock controller 4. The contact of a switch 19 in the unit 12 is closed by the magnetic action of a magnet 16 at the time of door closing, and a monitor signal indicating 'door closing' is input to the electric lock controller 4.

Title: Wattmeter
Inventor: TAKAHASHI HARUO
IPC: G01R22/00
Filed: 1979-03-15
Abstract: PURPOSE: To give information when a secondary voltage on the side of a main core does not become zero V due to the occurrence of an error and to accurately meansure the quantity of electric power through appropriate compensation, by monitoring a voltage which appears in the error compensation circuit of a current detection unit.  
     CONSTITUTION: A current detection unit comprises a current converter 21, a voltage comparator 22 and an error information section 23. The current converter 21 is provided with an error compensation circuit so that the secondary voltage across a secondary winding 15 around a main core 11 is eliminated by a voltage which appears across a secondary winding 13 around an auxiliary core 12. When the voltage between a grounded point 25 and another point 24 on the secondary side of the main core 11 does not become zero V due to a cause such as the change in the circuit constant of the error compensation circuit in the current converter 21 or the deterioration of the core, the voltage comparator 22 acts and its output changes from "L" to "H". As a result, the error information section 23 acts to indicate an error occurrence warning signal. Thus, error occurrence in the current detection unit of a wattmeter can be quickly discriminated and an appropriate measure can be taken.
