Title: Production of square fiber drum
Inventor: TSUMOTO HIROMI
IPC: B21D19/08
Filed: 1987-07-01
Abstract: PURPOSE:To reduce a production cost and to improve the storing efficiency of a drum by arranging a press forming tool on a cylindrical fiber drum and forming the fiber drum in a square shape by the pressing. CONSTITUTION:A square type core member 3 decomposable in each side 3a, 3b, 3c and 3d is provided at the center of a base 2 and the press forming tools 4a, 4b, 4c and 4d touching and separating by facing with each side are arranged. The fiber drum formed in a cylindrical shape is outer-inserted from the upper part in the core member 3 and the driving means 6 consisting of a hydraulic cylinder 5 is then driven to form a fiber drum 1 by deforming it in a square shape. Moreover the recessed part 13 for engagement is formed at an inlet port 8 and a recessed part 14 on the inner peripheral face of a cover body 15. Due to the forming being capable in a square shape directly from a circular fiber drum, the production cost of the square fiber drum 1 is reduced. The dead space at the storing time is reduced due to its square shape and the storing efficiency is improved.

Title: Variable wavelength filter
Inventor: NUMAI TAKAAKI
IPC: G02F1/23
Filed: 1989-06-26
Abstract: PURPOSE:To obtain the variable wavelength filter which is large in the variable tuning width of selected wavelength by controlling wavelength varying operation and an adjustment of a light gain almost independently of each other. CONSTITUTION:An active area 100 and a phase control area 200 are in buried structure for the confinment of carriers and lateral mode control and when carriers are injected in to a phase control area 200, the equivalent refractive index of the phase control area 200 decreases by plasma effect to cause a shift in the phase of light in the element, so that the transmission wavelength varies. When a current injected into the active area 100 is biased to a little bit less than an oscillation threshold value, on the other hand, incident light to the active area 100 is given a light gain by being amplified by induction emission. Then the light gain can be controlled with the carriers injected into the active area 100. The selection wavelength and light gain can be controlled nearly independently. Consequently, optical wavelength can be selected from a wavelength multiplex light signal of 20 channels.

Title: Muting circuit
Inventor: TANAKA HIROMICHI
IPC: H04B1/10
Filed: 1980-11-25
Abstract: PURPOSE:To eliminate a large variation of the sound volume, by adding a fade- in circuit to a muting circuit for data error. CONSTITUTION:Digital data 6 supplied from an input terminal T1 is checked for error data by a CRC check circuit 7 and is inputted to a data reproducing circuit 8 and is decoded and is subjected to D/A conversion and is outputted through a muting circuit 10 to an output terminal T2 as reproduced output signal 11. A fade-in circuit 9 uses a control signal, which is obtained by the CRC check circuit 7, as the input to control the muting circuit 10. Since a control voltage is changed from the low level to the high level gradually during the release of the muting state, the reproduced output signal 11 from the muting circuit 10 is faded in.

Title: Detecting circuit of dust sticking state
Inventor: YOSHITAKE YUUJI
IPC: G11B20/06
Filed: 1983-09-07
Abstract: PURPOSE:To eliminate the cause of drop-out and to improve the yield on production of recording medium by generating a dust sticking state detection signal, which indicates that the drop-out is caused by dust or the like stuck to a recording medium or a reproducing stylus, when the duration of a drop-out holding signal exceeds a specified time. CONSTITUTION:A frequency-modulated high frequency signal of a color video signal reproduced from a disc is supplied from a reproducing device to an input terminal 1. A monostable multivibrator 5 is triggered by the fall of the drop-out detection signal to generate a pulse having a prescribed pulse width and supplies this pulse to an OR circuit 6. The OR circuit 6 ORs signals to generate the drop- out holding signal which is in the high level continuously in the time when drop- out due to a dust sticking phenomenon is generated. When the duration of the drop-out holding signal exceeds a prescribed time, a counter 8 generates a high- level latch signal and supplies it to a latch circuit 10. Thus, the reproducible drop-out due to the deformation and a flaw of the disc and transient drop-out due to dust sticking are distinguished from each other in accordance with the duration of the signal.
