Title: Optical comb line filter
Inventor: NAKAMURA TAKAHIRO
IPC: G02B27/46
Filed: 1984-05-15
Abstract: PURPOSE:To attain comb line characteristics up to a high space frequency by selecting thickness and directions of optical axes of double refracting plates so that the total sum of optical path differences between ordinary rays and extraordinary rays passing the first double refracting plate and that passing the second double refracting plate are equal to each other. CONSTITUTION:Double refracting plates 7 and 8 are so arranged that planes including optical axes vertical to surfaces are orthogonal to each other, and a thickness d2 of the refracting plate 8 and a thickness d1 of the refracting plate 7 are so selected that a formula I is satisfied. The luminous flux made incident on the double refracting plate 7 are separated into ordinary rays L1 and extraordinary, rays L2, and an optical path difference l1 between both rays passing the double refracting plate 7 is given by a formula II. An optical path difference l2 between both rays passing the double refracting plate 8 is given by a formula III. Consequently, an optical path difference (l) between rays L1 and L2 after passage of both of the double refracting plate 7 and the double refracting plate 8 is l=l1+l2=0, and these rays are focused on the same image surface 12 DELTAW apart from each other. Thus, comb line characteristics are attained up to a high space frequency without influences of the F value of a lens and the selecting method of the image surface.

Title: Throw-away shorts
Inventor: MATSUURA IWAO
IPC: A61F13/49
Filed: 1995-04-20
Abstract: PURPOSE: To make it possible to prevent the uncomfortable feel of throw-away parts with gathers for the legs by oscillating guides which are inserted with plural pieces of elastic yarn for the legs at equal intervals and move back and forth in the transverse direction of a continuous sheet so as to be held always perpendicular to the loci for attaching the elastic yarn along the sheet, thereby adhering the elastic yarn at the equally spaced intervals. CONSTITUTION: The guide 11a is disposed with insertion holes 22 at equal intervals and one piece each of the elastic yarn 2 is previously inserted into these holes. The guide 11a is oscillated from solid line positions G1 (G3, G5) to broken line positions G2, G4. Namely, the guide 11a moves back and forth in the transverse direction of the back sheet 1 when the guide 11 is synchronized with the loci for attaching the elastic sheet 2 along the sheet and is oscillated in such a manner that the angle intersecting with these loci for attaching the yarn along the sheet is maintained. As a result, the elastic yarn 2 is adhered onto the sheet 1 by maintaining the equally spaced intervals at all times. Then, the intervals for adhering the elastic yarn 2 to each other are narrowed and the concentration of the elasticity restitutive force to the narrow area of the skin does not arise.  Pain, etc., are thus prevented.

Title: Thermal transfer recording device
Inventor: GENNO HIROKAZU
IPC: B41J17/24
Filed: 1988-04-19
Abstract: PURPOSE:To obtain stable ink tension and prevent generation of creases in an ink sheet by giving tension to the ink sheet by the braking force of a torque limiter. CONSTITUTION:If a drive motor 30 is driven clockwise to rotate, an ink sheet transport roller 8 rotates counter-clockwise. When the ink sheet 2 is drawn out of an ink sheet roll 1, a braking force works on an ink sheet roll holding reel 48 by a torque limiter. Consequently, when an ink sheet 2 is drawn out to a winding roll 11 side, a back tension is applied to the ink sheet 2 from the ink sheet roll 1 side, and therefore, the possibility is little that the ink sheet 2 might become loose or creasy. In addition, when a drive motor is reversed (counter-clockwise direction), the ink sheet 2 is transported in an opposite direction and a braking force works on a take-up roll holding reel 47 by a torque limiter 52, so that the ink sheet 2 does not become loose or creasy.

Title: Information recording and reproducing device, and information recording method
Inventor: TODA TAKESHI
IPC: G11B7/125
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To form highly accurate recorded marks by controlling the irradiation of a light based on a reflected light quantity to be detected for an nth time (n is a natural number) and a reflected light quantity to be detected for the next time while detecting states of a recorded part from the reflected light of a light to be irradiated on an information recording medium to suppress the fluctuation of recorded marks as much as possible. SOLUTION: A reflected light level in an unrecorded or erased state is detected with a first sampling pulse by irradiating a recording medium only with an erasing power in accordance with a power correction starting signal and a level to be detected with a next sampling pulse is predicted from the relation between the irradiation power and the reflected light level. Then, a setting power is changed according to the variation rate between a measured value and a predicted value by comparing the reflected light level measured with the next sampling pulse with the preliminarily predicated predicted level. That is, even when recorded marks are present already, mark shapes being the same as that of unrecorded marks are obtained by changing the setting power by the compared result between an (n+1)th predicted value to be calculated from an nth measured value and an (n+1)th measured value.
