It is fed into holding devices B, C at a constant speed, held so as to be slidable in the axial direction, also inserted through a bending device D in the rear and bent in the double dimensional direction. Subsequently, it is cut to prescribed length by a running cutting device E. On this way, a detector F is placed between the first holding device B and the second holding device C, and the feed- out length of the base material X is measured. In accordance with its measured length, the bending device D and the running cutting device E are brought to driving control through a controller G.

Title: Optical recording medium, and signal recording and reproducing device for such medium
Inventor: MATSUSHITA KATSUTOSHI
IPC: G11B7/004
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To enlarge a capacity of a recording medium by increasing a surface area in a forming surface of an information recording area, by forming the information recording area on an information signal forming surface, within the range of a specific angle against the information recording area forming surface and the substrate surface. SOLUTION: On the forming surface of the information recording area, an information recording layer 4 is formed at an angle of 0 deg.<θ<90 deg. to the forming surface and the substrate 1 surface. For example, if θ=45 deg., the forming surface 4a of a first information recording area and that 4b of a second are spirally formed at an angle of 90 deg. with each other, on the side of the information signal forming surface in the substrate 1 of a light transmissive resin. In this case, on the forming surfaces 4a, 4b, a cross-sectionally wedge-shaped groove is formed. The angle of incidence of a light beam is made nearly vertical on these forming surfaces 4a, 4b. As a result, a large capacity can be obtained for an optical recording medium 10, and simultaneously, complication can be avoided in an optical pickup structure.

IPC: H01L21/205
Filed: 1990-01-29
Abstract: PURPOSE:To enable high quality plasma processing to be performed rapidly by a method wherein multiple power supplies feed direct currents respectively to corresponding electromagnetic coils comprising an electromagnetic coil means. CONSTITUTION:When the processing of a semiconductor substrate 10 reaches the final stage after finishing the rapid processing in the primary and intermediate stage, the current values fed from the power supplies 13a-13e respectively to the electromagnetic coils 12a-12e are changed. For example, the current values fed to the electromagnetic coils 12a-12c positioned in the upper parts and those fed to the electromagnetic coils 12d and 12e positioned in the lower parts are changed respectively to 12A and 0A. Through these procedures, the electron cycrotron resonance region in magnetic flux density of 875 gauss moves to the upper part in a quartz made belljar 2 as shown by one point chain lines. That is, the plasma region in high density.high energy goes away from the semiconductor substrate 10. Resultantly, the processing in the semiconductor substrate 10 such as etching or film formation, etc., is weakened and decelerated. Therefore, the high quality processing can be performed rapidly.

Abstract: PURPOSE:To always output optical signals having the same polarity regardless of the polarity of electric signals by providing respective means for discriminating the polarity of plural pulse signals inputted from two-wire transmission lines, always outputting pulse signals having the same polarity and converting these output signals to electric signals. CONSTITUTION:The plural pulse signals at + or -24V inputted from two-wire transmission lines D1 are converted to plural pulse signals at + or -5V by a transmission I/F 51, and a power supply circuit 52 generates power supply at 5V. Each time the polarity of inputted output signals from the I/F 51 is inverted, a trigger pulse generation part 53 at the time of signal polarity inversion outputs trigger signals and starts or resets the count operation of a pulse width counter 54. A latch circuit 55 latches the input data of a D input terminal synchronously with the latch timing signal of the counter 54 and outputs those data through AND and OR circuits 56, 57 and 58 to an electric/optical conversion circuit 59. Thus, the circuit 59 can always output the optical signals having the same polarity regardless of the polarity of input signals from the transmission lines D1.
