Filed: 1989-12-28
Abstract: PURPOSE:To improve positioning accuracy by discriminating whether the difference between present position data and previous position data exists in the permissible range smaller than the absolute permissible range or not and rewriting the present position data as the previous position data if the difference exists in the permissible range. CONSTITUTION:A jig controller 10 in a system to discriminate the positioning of a furnace 2 and a mold 1 drives a cylinder 11 as an actuator and positions the mold 1 on the furnace 2 while clamping the mold.

The discriminating device 13 makes judgment and continues the casting operation if the positioning is normal. An alarm is emitted if the positioning is abnormal. The absolute permissible range DELTAP and the permissible range DELTAepsilonfor every position detecting operation are previously set in the discriminating device 13. The present position data Da is rewritten as Db if the difference between the Da and the previous position data Db exists within DELTAepsilon smaller than the DELTAP. The normality and abnormality of the operation are decided in this way and the positioning accuracy is improved.

Inventor: ODA YUJI
IPC: F02B47/02
Filed: 1992-12-25
Abstract: PURPOSE:To carry out a stable ignition and combustion by a method wherein a fuel passage is divided and connected to the passage of inert material even if the amount of inert material is increased. CONSTITUTION:The inert material supplied into a fuel valve by means of a control valve 16 during the stop period of fuel injection flows to the needle valve 11 side and divided injection pipe 21 side.

IPC: D06H3/08
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To simply prepare various white-and-black information by preparing information for every call unit or block unit with an information yarn with a color possible to be discriminated by a camera at the time of preparing information for cloth or the like. SOLUTION: The thickness of vertical information yarn 10 is set up to the same thickness as horizontal information yarn 11, the color of each yarn can be discriminated by a camera, and when the yarn 10 is white, black is used for the yarn 11 to display information. Since the yarn 11 of a two-dimensional code to be prepared is black yarn, the yarn 11 is woven so as to be front side against the yarn 10 when information is 'black', but a fixed point is inserted almost in every cell, the horizontal information yarn 11 and the vertical information yarn 10 are successively woven while selecting the side of the yarn 10 on which the yarn 11 is arranged by considering adjacent right and left cell information. Since the fixed point of the yarn 11 is the length of almost one cell, the yarn can be prevented from being caught and cut off and accurate information display can be attained.

Title: Switchover controller
Inventor: EDA YOSHIKO
IPC: H04L69/40
Filed: 1993-12-22
Abstract: PURPOSE:To prevent the switchover of a system when a package is extracted by latching a switchover signal only when a trigger signal having a pulse width equal to or more than a prescribed pulse width is inputted. CONSTITUTION:A latch pulse generation circuit 11 transmitting a latch pulse 12 of a fixed pulse width is provided on a control package 6. A pulse width monitoring circuit 13 monitoring the pulse width of a latch pulse 12 and outputting a latch pulse 130 only when the pulse width is a prescribed width or more is provided on a reception package 5. Therefore, even if noise is generated and is inputted to a reception package 5 as a latch pulse 12 when a control package 6 is extracted, a latch pulse 130 is not outputted because the width is smaller than a prescribed width and the contents of the output of a switch circuit 15 is not switched. Therefore, when the control package 6 is extracted, a protective state is not required, and even if the package is erroneously extracted, the contents of the output is not switched.

Title: Immersion nozzle for continuous casting
Inventor: KUSHIDA KOICHI
IPC: B22D41/50
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To prevent the development of clogging in a nozzle by forming the spouting passage of an immersion nozzle whose shape becomes narrower toward the tip part and upper ridge angle forms an acute angle to the outer ridge of the nozzle side wall. SOLUTION: The immersion nozzle 1 has the opening hole part 7 on the side wall 4 at the lower part 6 of nozzle near the lower end of a molten steel passage 3. The angle θ of the upper ridge 8 of the spouting passage 3 formed to the outer ridge 10 of the nozzle side wall is formed to the acute angle. The lower ridge 9 of the spouting passage 3 is inclined downward and the spouting passage 3 has narrower shape toward the tip part. Since the spouting speed is gradually slowed down in the conventional nozzle, the clogging in the nozzle is developed. Since the spouting speed is increased as going to the tip part in the immersion nozzle 1, alumina in the spouting passage 3 is not precipitated.  In the case of being >=90 deg. the angle θ, the spouting speed is reduced but in the case of being this angle θ to excessive acute angle, the breakage of the nozzle 1 is developed and then, the angle θ is desirable to be 30-85 deg.. A straight cylindrical type single hole immersion nozzle 1 having gentle tapered part to the outer shape toward tip part in the tip end part 5 can be used, too.

Title: Locking confirmation device
Inventor: SATO TAKEHIKO
IPC: E05B41/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To properly confirm a locked state at a remote place. SOLUTION: An oscillation circuit 3 resonating with a specific frequency is built into a dead bolt 2. Furthermore, a plurality of oscillators 11 and 12 connected to a coil L2 in a door frame 4 are respectively set at different frequencies f1 and f2 , and one of the frequencies f1 and f2 , or the frequency f2 is set at the same value as the resonance frequency of the oscillation circuit 3 in the dead bolt 2. Furthermore, when the dead bolt 2 is coupled to a receiving hole 5, the coil L2 having the plurality of the oscillators 11 and 12 connected, and the oscillation circuit 3 in the dead bolt 2 are electromagnetically coupled to one another, thereby sending signals on the plurality of the frequencies f1 and f2 to the dead bolt 2. Also, when the output of the oscillator 12 having the same frequency f2 as the resonance frequency of the oscillation circuit 3 changes, due to the internal impedance of the oscillator 12, the dead bolt 2 is identified as coupled to the receiving hole 5 and kept in a locked state. As a result, an indicator 21 lights for showing the locked state. On the other hand, a status is regarded as related to an object other than the dead bolt 2, when the output of the oscillators 11 and 12 having all of the frequencies f1 and f2 gives a change or the output of thereof gives no change.
