Title: Discriminating system of magnetic tape
Inventor: IMAMURA AKIRA
IPC: G11B23/36
Filed: 1981-02-18
Abstract: PURPOSE:To discriminate number of recording tracks on a tape automatically, by providing a function writing a track number discriminating mark on the magnetic tape and a function detecting and discriminating the number of tracks. CONSTITUTION:When a write instruction is inputted from an upper-order device 12, a system control section 10 sets the system to a write-mode. Then, a discrimination mark recording track is selected, the track number is checked, and if the number of track is 8, an L2 section is erased, the write-in track is selected and data write-in is started. On the other hand, if the track number is 4, a track number discriminating mark 23 is recorded on the L2 section on a tape. When a read instruction is inputted from the device 12, the control section 10 sets the mode to read-mode, selects a track where the mark 23 is recorded, and when the formatter 9 detects a discriminating mark code, data are read out. Thus, the number of recording tracks can automatically be discriminated.

Abstract: PURPOSE: To improve the stability of arc column and improve the performances such as current density and output by shunting gas at a suitable ratio in a plurality of annular channels formed in the overcoat type plasma arc torch in said torch.  
     CONSTITUTION: In the positive polarity plasma arc torch, first the 1st gas 8 being inert gas is flowed and an arc 20' is produced between a cathode rod 1 and the 1st overcoat 4 by the high-frequency power source built in a power source 15, and switches 16, 17 are subsequently opened to shift the arc 20' to an electrode 18, whereby it is made to an arc 20. Thence, inert gas is flowed at a suitable shunt ratio in the 1st and 2nd annular channels 3, 5, and the operation is done. More specifically, the gas of the flow rate substantially equal to or more than the flow rate of the maximum value coordinates of the characteristic curve of the heat losses of the outermost overcoat 6 versus the gas flow rates in the inner annular channel 3 is flowed in the channel 3 and the remaining portion from a fixed total flow rate is flowed to the channel 5.

Title: Fusion splicing method for constant polarization optical fiber
Inventor: IMORI TSUNEFUMI
IPC: G02B6/255
Filed: 1993-01-18
Abstract: PURPOSE:To enable the easy and rapid execution of fusion splicing by cutting a constant polarization optical fiber, rotating at least one of the two fibers at a prescribed angle and fusing the cut faces to each other at the time of fusion splicing the constant polarization optical fiber in such a manner that the plane of polarization thereof has the prescribed angle. CONSTITUTION:The constant polarization optical fiber 1 is drawn out to a prescribed length from a bobbin 2 and the intermediate films thereof are removed. The fiber 1 is then fixed by clamps 3, 4 rotatable at theta, and is cut between these clamps 3 and 4. The fibers 1 are then rotated at the prescribed angle and are fused by rotating at least either of the clamps 3, 4. The parts where the coatings are removed are thereafter reinforced by a reinforcing material 5 and are cut to the prescribed length. The fiber may be continuously taken up by a bobbin 2b without cutting after the fusing and reinforcing. As a result, alignment is enabled even if an intricate aligning mechanism for detecting the prescribed angle is not used. The continuous supply of one piece of the fiber 1 from the bobbin 2, etc., is thus possible.

Title: Surface flaw inspection device
Inventor: SUZUKI MOTOYUKI
IPC: G01N21/952
Filed: 1988-02-05
Abstract: PURPOSE:To improve the accuracy of surface flaw inspection by making reflected light from a curved rotary body incident on a camera with the nearly uniform quantity of light entirely in the direction of the center axis of the rotary body. CONSTITUTION:The bent part of the surface of the curved rotary body 1 consists of three parts L1-L3 approximated to straight lines in a direction parallel to the center O of rotation. Then three light sources 11-13 are arranged corresponding to those three parts and installed at specific angles so that their light beams are reflected by the respective parts L1-L3 and light incident on the linear camera 3 becomes a regular reflecting surface. Consequently, the output of the sensor in the camera 3 is entirely uniform corresponding to the position along the center axis O, so when there is a flaw such as a recessed part and a scratch in the surface, it appears as a dark part in the reflected light from the part.

Abstract: PURPOSE: To provide pressure release and pressure lock function with a small number of parts by providing a button energizing means energizing a pressure button in an anti-pressing direction and having weaker energizing force than a tray energizing means. CONSTITUTION: In the case of enclosing a tray 2 in the storage chamber 10 of a console box 1, the tray 2 itself is pushed into the storage chamber 10 against the energizing force of a tray energizing spring. The tray 2 is thereby pushed into the back of the storage chamber 10. When the tray 2 reaches a specific position, the tip of a locking member 35 energized toward the right by the energizing force of a locking spring 36 enters into the first through hole 12 of a wall part 11 forming the storage chamber 10 of the console box 1. When the pressing of the tray 2 is stopped in this state, the tray 2 is pushed back by the tray energizing spring, and the tip of the locking member 35 comes in contact with the hole wall of the first through hole 12 of the wall part 11 so as to be locked.  The tray 2 is thereby kept in the state of being enclosed in the storage chamber 10 of the console box 1.
