Patent JP-H03108147-A (JP)
Title: Tension controller
Inventor: KOMODA NORIKIYO
IPC: G11B15/43
Filed: 1989-09-22
Abstract: PURPOSE:To secure the stability of tension even when tape speed is fluctuated by discriminating the rotating state of a reel, and judging whether or not the latching operation of a multiplication circuit should be performed corresponding to whether the rotating state shows a transient state or a stationary state. CONSTITUTION:The reel 2 is rotated integrally with a reel motor 4, and rotating speed information is detected with a rotating speed information detecting means FG 5. And the information is converted to cycle information at a rotary cycle information conversion means 6. Since the speed of a tape 1 is kept constant, the cycle information outputted from the conversion means 6 is torque information proportional to the radius of the reel 2. Furthermore, it is discriminated whether the rotating state of the reel 2 is set at the transient state or the stationary state with the output of the conversion means 6, and a result is outputted from a comparison means 7. A holding means 9 is provided which latches the output of the multiplication circuit 8 when the output shows the stationary state, and latches no output when it shows the transient state. Thereby, it is possible to secure the stability of the tension even when the speed of the tape 1 is fluctuated.

Title: Method for peeling soot of optical fiber perform
Inventor: MIKAMI TOSHIHIRO
IPC: B08B3/04
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To efficiently peel the defective soot forming the porous glass layer of an optical fiber preform by blowing a high-pressure water stream at an angle of a specific range with the plane normal to the axis of a core rod. SOLUTION: A high-pressure water stream is blown at the angle of range within ±60 deg. with the plane normal to the axis of a core rod 3 while the water stream is risen along the longitudinal direction of the defective soot 1. At this time, the cutting function by high-pressure water stream is exhibited to notch the surface of the defective soot 1 without rotating the defective soot 1. While the defective soot 1 is rotated, the high-pressure water stream is descended and blown along the longitudinal direction of the defective soot 1. The peeling of the defective soot 1 is executed by repeating the stage. When the end of the soot 1 is tapered to a high density and is hardly peelable, the water stream is pressed to the soot from the larger diameter side of the taper, by which the efficient peeling is made possible.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive bar code reader, which can precisely read data under high-speed transport by reflecting a reading amplification factor matching the state of a bar code label to the reading amplification factor of the next bar code lebel, whenever reading is executed and changing the amplification factor, so that an optimum state is obtained with respect the bar code labels which are previously and simultaneously printed. SOLUTION: CPU counts the number of decoding success times at the amplification rates of respective amplification factor blocks, which is previously set, until a bar code label passes through. When the count exists at the center amplification factor of a present amplification rate block N with the distribution of the number of success times, next read setting is set at the present amplification factor block as is. When distribution is biased toward the greater amplification factor, an amplification factor block (N+1), whose amplification rate is higher by one is set. The optimum amplification factor block is reviewed at reading of the next bar code lebel by every reading result of the bar code label, and decoding is executed by the optimum amplification factor block.
