Patent JP-H03176815-A (JP)
Title: Production of magnetic recording medium
Inventor: SANO SHIGERU
IPC: G11B5/84
Filed: 1989-12-06
Abstract: PURPOSE:To remove the cut powder produced during injection and to cool the lapping area to prevent welding of resin of a lapping tape by blowing clean gas on the working area during working. CONSTITUTION:A lapping tape 4 is sent at a certain speed on a magnetic medium 7 which is rotating so as to uniformly press the tape 4 with a pressure roller 5, while the tape is moved along the radius direction of the medium 7. During this process, clean gas 8 is blown from a injection nozzle 6 to the working area. By this method, the cut powder produced by lapping can be removed by injection of gas, and besides, the area around the contact surface of the medium and the lapping tape is cooled by the blown gas. Thus, elevation of temp. in the contact area due to processing heat is suppressed and welding of the resin is prevented. Thereby, the obtd. medium has high cleanliness.

Title: Thermal transfer recording apparatus
Inventor: AWAI TAKASHI
IPC: B41J11/42
Filed: 1989-12-06
Abstract: PURPOSE:To suppress the fluctuation of the feed length of an ink sheet to a recording medium to a predetermined range by mounting at least two feed mechanisms rotationally driving the take-up roll of the ink sheet and change over the feed mechanisms corresponding to the take-up length of the ink sheet. CONSTITUTION:When the relative speed of an ink sheet 14 to thermal head 13 is set to V1 and the relative speed of recording paper 11 to the thermal head 13 is set to Vp, the value of (n) at the time of n-times recording is shown by n=Vp/V1. Even when the value of (n) is set to 6 at the beginning, the take-up quantity of the ink sheet 14 increases and the value of (n) becomes gradually smaller. When the take-up quantity of the ink sheet 14 reaches a predetermined value, the rotation of an ink sheet feed motor 25 is reversed and, when the transmission route of the rotation to an ink sheet take-up roll 18 is altered from a transmission gear 61 to a transmission gear 63, the value of (n) is reset to 6. By this constitution, the fluctuation of the value of (n) can be suppressed to a predetermined range.

Abstract: PURPOSE:To prevent the defect of a coating film so as to obtain a high quality shadow mask by coating water base material having resistance to etchant on the shallow concave small hole portion formed on the face of shadow mask material maintained at a fixed temperature. CONSTITUTION:Photo-sensitive films 2 having respectively a small diameter portion 3 and a large diameter portion 4 are formed on both faces of shadow mask material 1. Etchant is sprayed on both faces, and both small diameter portion 3 side and large diameter portion 4 side are primarily etched so as to form shallow concave shapes with fixed depths.

Thereby, the leveling performance of coating liquid, and the defoaming performance of bubbles in holes are improved, and an etching resistance layer 5 is formed so as to be filled completely without bubbles and unfilled portions. By performing secondary etching from the large diameter portion 4 side thereafter, the occurrence of abnormal diameter holes is prevented so as to form high quality and minute electron beam passing holes and it is possible to obtain a fine shadow mask.

Title: Wavelength conversion element
Inventor: KOUDA HIKARI
IPC: G02F1/35
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to efficiently execute wavelength conversion stable over a long time without deteriorating an element surface by working an incident surface and exit surface to the Brewster angles which take the deflection direction of the former with a laser beam and that of the latter with converted light into consideration. SOLUTION: The Brewster angle θB (in) is calculated by defining the refractive index of the atmosphere on the outside of the element 1 as n1 and the ordinary ray refractive index of the wavelength ω of the incident laser beam 3 of the wavelength conversion element 1 as n2 . The laser beam is introduced without reflection into the crystal if the laser beam is made incident in such a manner that the polarization direction attains P polarized light and the angle between the propagation direction of the light and the normal of the incident surface attains the angle θB (in). The converted light generated in the crystal is an extraordinary ray and, therefore, intersects orthogonally with the deflection direction of the incident light 3.  The Brewster angle θB (out) is calculated by defining the refractive index of the extraordinary ray of the wavelength of 2ω as n1 and the atmosphere as n2 . The converted light generated in the crystal may be emitted without reflection at the light-emitting surface 5 if the light-emitting surface 5 is so worked that the polarization direction of the converted light attains P polarized light and the angle between the propagation direction of the light in the crystal and the normal of the light-emitting surface 5 attains the angle θB (out).
