Title: Manufacture of atomized iron powder
Inventor: MANDO HIROMUNE
IPC: B22F9/08
Filed: 1978-04-21
Abstract: PURPOSE: To manufacture the titled iron powder of high quality almost free from the slag inclusion, by making impossible the slag to flow into the cylinder vertically installed in the tundish (TD), to pouring the molten steel into the TD through the cylinder, and to make the molten steel to fall down through the nozzle.  
     CONSTITUTION: The cylinder 15, for preventing the slag inclusion, is vertically installed in the TD 4; hereby, the slag 5 can not flow into the cylinder 15, and then, the molten steel 2 is poured from the ladle into the TD 4 through the cylinder 15. As a result, the slag 5 is always shut out by the cylinder 15, so that there is no danger of including the slag 5 in the molten steel 2, and only the molten steel 2 flows out of the nozzle 6. Moreover, since the slag 5 always covers the surface of the molten steel 2, the heat insulation effect and the antioxidizing effect are improved. The molten steel 2 flowing out of the nozzle 6 is treated by the water- atomization method or the gas-atomization method, and the high quality atomized iron powder almost free from the slag inclusion can be manufactured.

Title: Composite magnetic head device
Inventor: MIYAZAKI MAKOTO
IPC: G11B5/265
Filed: 1990-02-28
Abstract: PURPOSE:To effectively improve magnetic efficiency at the time of recording and reproducing by setting the core leg of a 1st magnetic core shorter than the core leg of a 2nd magnetic core. CONSTITUTION:The core leg 5A at one end of the magnetic core 5 for low frequencies is formed shorter in the length than the other two core legs 5B, 5C. A reproducing/writing coil 6 for low frequencies is wound around the core leg 5A. The 1st magnetic core 1 is formed of a back bar 7, the connecting part 5B, the core legs 5A and 5B and the R/W coil 6 for low frequencies. Since the core leg 5A of the 1st magnetic core 1 of the magnetic head part 3 for low frequencies is set extremely shorter than the core legs 5B, 5C of the 2nd magnetic core 2, the magnetic resistance in a closed loop is decreased. The magnetic efficiency is effectively improved in this way.

Title: Method and device for laying wire material for communication
Inventor: SANO HIROAKI
IPC: H02G1/08
Filed: 1990-02-28
Abstract: PURPOSE:To feed an optical fiber unit smoothly into a conduit by force by controlling both or either of the supply speed and laying speed of the wire material for communication so that the slack quantity of the wire material for communication in a container becomes constant when the wire material for communication which is put in the enclosed container is inserted and laid with pressurized liquid. CONSTITUTION:The device is provided with a means 8 which detects the displacement of the wire material for communication optically without contacting it before the wire material unwound from a bobbin 5 is supplied to the conduit and a dancer which is arranged at the passing position of the wire material for communication while a constant load is placed, and the wire material is brought into contact; and the displacement of the dancer is detected and the slack quantity is detected from the displacement. Then the excessive length of the wire material for communication in the laying device is limited within a proper range by controlling both or either of the supply speed and laying speed of the wire material for communication with the detection signal of the detecting means 8 so that the slack quantity of the wire material for communication in the container becomes constant. Consequently, the wire material for communication in the laying device is prevented from being curved or wound disorderly owing to its stay in the laying device.

Title: Method for generating output based on plan
Inventor: AOSHIMA HIROKAZU
IPC: G06F15/00
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To perform the explanation that is subject to the plan execution order and also the explanation subject to the inverse execution order when the output is generated based on a plan that is expressed in a network by preparing the specific tables and linking the relative information on these tables with each other. SOLUTION: In regard to the nodes corresponding to the acts of a plan expressed in a network, each of tables 100 to 103 contains an ID 111, a subsequent node 112, a preceding node 113 and the additional information 114 of every node. Then the relative information on the tables 101 to 103 are linked with each other. When the nodes of the plan are traced along the link and also the information are collected to generated the output based on the plan, the information of the type corresponding to the moving direction of the relevant time is acquired from the information 114. Based on this information, the output is carried out. At the same time, the information showing the moving direction of a specific type to which the acquired information is corresponding is also recorded when the information are acquired and stored. Based on this recorded information, the output mode is changed.

Title: Whole electronic type analog display timepiece
Inventor: MORIYA TAKEHIRO
IPC: G04G9/02
Filed: 1981-04-01
Abstract: PURPOSE:To ensure a clear recognition for the fact that the short and long hands overlap, by turning on and off the display of one hand in case the radiately arranged long and short hands overlap. CONSTITUTION:The different 60 sets of radial segment electrodes are driven by the minute counter CT1 and the 60-notation hour counter CT2 which receives an output from CT1 with every 12min via the decoders D1 and D2, control circuit A and driving circuit DR. Thus a display of hour and minute is given by the long and short hands arranged radially. For instance, in case the long and short hands overlap at 12:00 or other time, the open/close of the gate is controlled for circuit A by the outputs of decoders D1 and D2 to apply the 1-sec period signal (b) or the like to the circuit DR. Thus either one of the long and short hands has a blinking. Otherwise both hands can be blinked. Thus an overlap of the long and short hands never be mistaken for a fault unlike the case in which the display of one hand is erased.

Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To make accurate surveying possible even in a small-bore tunnel and reduce the amount of labor required for surveying at curved parts of a large-bore tunnel. SOLUTION: Rulers 21 flexibly connected to one another in such a way that their lengths between the connections 22 are known are used in surveying the position of a shield machine 10. A flexing-direction detecting part 22 for detecting the flexing direction of the rulers 21 is provided at each connection 22 to detect the position of the front ruler 21a from the rear ruler 21b. In this case, the rulers 21 between them can be arranged freely. The position of the rear ruler 21b is surveyed by a total station 28 placed on a reference point O. The position of the shield machine 10 with respect to the rulers 21 is measured by a total station 25 placed on the front ruler 21a. Thus even if an obstacle or curve exists between the reference point O and the shield machine 10, the position of the shield machine 10 can be surveyed from the reference point O.
