Title: Production of fiber grating
Inventor: MORI TSUNEO
IPC: G02B6/10
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to form fiber gratings of different reflection wavelengths with one piece of phase mask by impressing tension on an optical fiber and controlling the reflection wavelength of the light signal by Bragg diffraction gratings at the time of irradiating the phase mask with a UV laser beam. SOLUTION: At the time of irradiating the optical fiber 1 with the UV laser beam 4, the reflection wavelength of the light signal by the Bragg diffraction gratings is controlled by impressing the tension on the optical fiber 1. Namely, the optical fiber 1 is fixed to the V-groove of a quartz plate 2 with a V-groove and the phase mask 3 is installed thereon in tight contact therewith. The phase mask 3 is irradiated with the UV laser beam 4 via the slits 5 from an arrow direction. The one end of the fiber 1 is securely fixed by a fiber clamp 6. The other end of the fiber is lowered via a pulley 7 where a weight 8 is attached to the fiber 1 to impress the tension on the fiber 1. The gratings of the short reflection wavelengths are obtd. after the release of the tension.

Filed: 1994-05-16
Abstract: PURPOSE:To shorten the axial sizes of roller supporting members and make a transmission totally compact by arranging the first and second wrapping transmission members and the third wrapping transmission member spaced each other so as to hold a roller between the roller supporting members. CONSTITUTION:The first and second wires 82, 84 and the third wire 86 are spaced each other upward and downward so as to hold a roller 45b between a pair of trunnions 59a, 59b of transmission units, and so the axial sizes of the trunnions are shorter. Specially, the downward axial sizes of the trunnions 59a, 59b are shorter, and so the corresponding downward size of a transmission is shorter and the transmission is made totally compact. In addition, the trunnions 59a, 59b are made longer upward to have necessary thicknesses and so the radii of the upper ends of the trunnions 59a, 59b can be smaller than usual. In this way, the size of a transmission case 22 can be smaller as the radii are smaller.

Title: Record start timing generating circuit
Inventor: FUJIWARA TSUNEO
IPC: G11B20/10
Filed: 1990-04-17
Abstract: PURPOSE:To make a time deviation of record start timing so as always to be put within a half of a clock cycle by correcting the timing signal in accordance with the case when an advance or delay of the time of timing signal is going to exceed a half of the clock cycle. CONSTITUTION:An error deciding circuit 2 is constituted of a register 10, adding device 11 provided with a carry terminal CY, and latch 12 provided with a latch enable terminal LE. When accumulated timing errors exceed a half of the clock cycle, an overflow in the adding device 11 is generated and the carry terminal CY becomes the high level state. Consequently, a set value N2 of the register 5 is selected in a selector 6, and a counter 9 operates as the (N2+1)-ary counter, then the record start timing of a sector head is corrected. Thus, the time deviation of record start timing for the sector head can be always put within a half of the clock cycle.
