Title: Control ling system of gate
Inventor: KOTAKI RINTAROU
IPC: G05D7/00
Filed: 1980-03-24
Abstract: PURPOSE: To give a long life to a gate by reducing wear of mechanical parts by a method wherein only one gate is operated when the difference between the opening of the main gate and that of subsidiary gate reaches to a certain value.  
     CONSTITUTION: When instructed to lower gates, only the main gate 2 descends. When the value obtained by subtracting the opening Hs of the subsidiary gate from the opening Hm of the main gate became equal to the safe control allowance ΔH, the descent of the gate 2 is stopped. After that time and when instructed to lower gate, the subsidiary gate 3 descends within the limitted value of Hm-Hs≥L-ΔH (where L is the height of the main gate 2). This means the subsidiary gate 3 stops when the opening Hs becomes zero. Further, the gate control ceases when the main gate 2 descends a predetermined distance.

Title: Agitation method
Inventor: SADA EIZOU
IPC: B01F13/08
Filed: 1979-03-29
Abstract: PURPOSE: To accelerate the material transfer and the heat transfer through agitation or turbulance produced in the vicinity of phase interface by a method wherein magnetic material particles or the same particles covered with nonmagnetic material are arranged on the phase interface and are made to spin and to revolve by use of rotating magnetic field.  
     CONSTITUTION: In a container 1, gas phase 2 exists at upper part and liquid phase 3 at lower part. On the interface of gas-liquid phases floated are magnetic particles 4 which consist of magnetic material such as iron oxide covered with nonmagentic material such as paraffin to provide a specific gravity smaller than the liquid density. A permanent magnet 5 is arranged in the gas phase 2 some distance from the phase interface. This cuases the magnetic particles group to be floated just below N and S poles of the permanent magnet 5. By rotating the magnet 5, particles group spins and revolves on the interface, in the same direction as magnet rotation. This results in agitation or tubulance on the interface or its vicinity. Accordingly, this agitation or turbulance action improves material transfer and/or heat transfer.

Title: Hemming method and apparatus for welded can drum
Inventor: YAMAGISHI HIDEAKI
IPC: B21D9/12
Filed: 1981-03-13
Abstract: PURPOSE:To prevent occurrence of buckling phenomena by making hemming work making the projection of end of a cylindrical welded can drum that advances along the hemming part of a flange disk not knocking condition. CONSTITUTION:Uneven escaping members 5 consisting of a group of upright rolls 4, 4... are provided between the flange disk 2 and flange ring of a hemming device 1. Using this device 1, an opening at the end of a welded can drum A is fitted to the parallel part 2a of the disk 2. The open end of the can drum A is moved forward from the parallel part along the hemming part 2b and hemmed. Next, the outermost rim of the hemming part is knocked against the innermost faces of rolls 4, 4 of the member 5. At this time, the projection of the can drum A faces a clearance 8 by rotation of the roll 4, and does not knock against rolls 4, 4 before other parts except the projection B knock against the rolls 4, 4.  Thus, load resistance at the projection B is not generated. Consequently, local  buckling phenomena are not caused in the can drum A.

Title: Viterbi decoding method and viterbi decoding circuit
Inventor: IWATA JUN
IPC: H03M13/41
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of an output composite signal without a complicated configuration by executing a path trace(PT) whose final arrival state is taken as a start state and outputting its synthesized signal as an object signal when a decoded signal obtained by the PT from a state has an error and the final state and the start state of the PT differ from each other. SOLUTION: An ACS arithmetic processing is repeatedly executed, a path is selected and a path metric(PM) is updated and a path selection signal is stored in a path memory 26. When the ACS arithmetic operation is finished, a maximum likelihood state Ss is recognized and a path trace back(TB) is conducted to obtain a decoded bit string A. Furthermore, an arrival state Sr at the end of TB is obtained. An error in the decoded bit string A is checked to discriminate the presence of error. When any error is in existence in the array A, the states Ss and Sr are compared and when both are coincident, an output bit is selected. On the other hand, when no error is in existence, whether or not the output bit string A or B is used or they are used after correction or the like is decided and an output bit string is sent.

Title: Tuning position detector
Inventor: TSUNENO JIYUICHI
IPC: H03J1/04
Filed: 1981-03-13
Abstract: PURPOSE:To detect a tuning state, and the extent and direction of a shift from a tuning position by a simple circuit, by using a voltage frequency converter, and driving one LED at a frequency which corresponds to an input signal level. CONSTITUTION:A received signal is amplified by an amplifier 11 and then sent to a V-F converter 12 to be converted into pulses which have a frequency corresponding to an input signal level. Those output pulses are sent to an LED13 fitted to a slider 14 moving on a scale 15. When the slider 14 is at a tuning position, the LED13 lights up continuously, and when it shifts from the tuning position, the LED13 flashes. The flashing speed becomes higher and higher as the slider shifts from the tuning position more and more, and becomes lower and lower as the slider is closer and closer to the tuning position. Thus, the simple circuit detects a tuning state and the extent and direction of the shift from the tuning position.

Abstract: PURPOSE:To prevent subsequent damage of furnace wall refractories and to start up smoothly a vertical furnace with preheating of a charging raw material in the startup of said furnace by selecting freely raw material charging conditions and heating temp. and selecting an adequate temp. rising speed. CONSTITUTION:A raw material is charged under the same or approximate condition as the condition in an ordinary operation into a furnace after building of refractory walls and temp.-controlled heating gas is introduced through the tuyere in the lower part of the furnace.

Title: Welding device and method
Inventor: HUTCHISON RICHARD
IPC: B23K9/095
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent agglutination of a wire to a weld joining part when the arc welding is finished. SOLUTION: A wire supplier 801 supplies a wire 802 to a welding article 803 of a work 806 via a welding torch 804. An arc voltage is used to determine if a desired arc length exists and to adjust a long term command as well. An electric current command at every short circuit is led out from a real time arc current, and a welding speed is controlled by adjusting the electric current command instantaneously or at every short circuit. A point of time when a short circuit is going to be eliminated is detected at real time by using a function obtained by subtracting the time differentiation from the arc current time differentiation. A stop algorithm is used to monitor the arc at every short circuit. When the arc welding is finished, an ultra low current level is supplied to avoid a formation of a ball.  When a short circuit takes place after the low current level, an outbreak energy is supplied to solve the short circuit and, once the short circuit is solved, the ultra low current is supplied again to avoid forming of a large size ball.

Title: Shock absorber and adjusting method of damping factor thereof
Inventor: STEED DAVID L
IPC: F16F9/44
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To provide a shock absorber with a structure having two damping characteristics aimed at soft comfortableness and hard comfortableness and continuously variable dampings are performed therebetween. SOLUTION: An adjustable damping shock absorber involves a pressure tube 14 holding therein a piston valve assembly 16 slidable. The piston valve assembly 16 comprises a compression valve assembly 32, 34 and an extension valve assembly, both biased at their closed positions. The damping factor of the absorber is thus adjusted through a selective variation in biasing force applied to either of or both of the valve assemblies. The larger biasing force produces a hard damping characteristic of the absorber, while the smaller biasing force produces a soft one.
