IPC: G11B7/26
Filed: 1985-05-22
Abstract: PURPOSE:To shorten the work time by exposing simultaneously plural grooves by one rotation of a substrate by using a parallel fringe-shaped optical image by a holography, and subsequently, exposing the next plural grooves by crossing over its plural pieces. CONSTITUTION:A laser beam from a beam source such as an argon laser, etc. is converted to a plane wave 15 by a collimator 14. Subsequently, two beams 20, 21 which is split by a beam splitter 16 pass through different optical path lengths and reach on a resist 12 on a substrate 11, and the phase is shifted so that an interference fringe can be formed on the resist. An interval of parallel fringes by the interference is determined by a crossing angle of two beams 20, 21 and a wavelength of the beam, therefore, it can be adjusted by changing an incident angle of the beam. By a parallel fringe-shape hologram image which is formed on the resist in this way, a pattern exposure of a concentric circle shape of plural pieces, for instance, 500 pieces is executed, and subsequently, the beam or the substrate is moved in the radial direction by a beam diameter, for instance, by a portion of 1.0mm, and the same pattern exposure is executed again. In this way, the work time can be shortened.

Title: Resin bonded type rare-earth magnet
Inventor: SAKURAI MITSURU
IPC: C08G59/00
Filed: 1988-04-30
Abstract: PURPOSE:To make it possible to conduct a complete kneading work in a short period by a method wherein, when an epoxy resin is added, the epoxy resin dissolved with an organic solution is used. CONSTITUTION:Epoxy resin, which is dissolved into an organic solvent, is used as a binder for the magnetic powder having the fundamental composition of a rare-earth metal and a transition metal. The viscosity of the resin used when a resin-bonding type magnet is formed is high as 10,000-20,000cps, and adding quantity is small as 1-15vol.%, but this material makes a kneading work difficult. Therefore, if the epoxy resin is used by diluting it with an organic solvent, the degree of its viscosity is reduced, and at the same time, the quantity of binder (organic solvent + epoxy resin) can be increased when it is added, and the kneading work of the resin can be conducted easily. Consequently, the resin can be kneaded completely in a short period, and a resin-bonded type magnet can be obtained at low cost.

A magnet cylinder 20 at, the outer end of the shaft 18 is positioned confronting a magnet rod 22 through a bushing 21 secured to the roller concerned 1. This magnet rod 22 is fixed to a rotary shaft 23 drawn out of the roller 1, and is supported by a bearing 24. When the rotary shaft 23 is rotated, the magnet cylinder 20 and shaft 18 rotate, and the bulkheads 16 move while rotating along the feed screw 19 and stop with stopping of the rotary shaft 23 in that place. Steep temp. gradient near the end of the tab of thermal load can be avoided by the uniform heating effect of the thermo-medium encapsulated in the jacket chamber. This enables uniform heating of the thermal load and proper pressurization for it.
