Title: Sample surface observation device
Inventor: HIRAI TERUJI
IPC: G01N23/225
Filed: 1986-09-30
Abstract: PURPOSE:To make it possible to control the beam intensity always constant while continuing the optical observation, and to improve the accuracy and the efficiency of measurement, by controlling the emitting beams with a focus lens and an object lens depending on the absorption current of a thin film transparent filter. CONSTITUTION:As the intensity of electron beams emitted from an electron gun is weakened, the absorption current detected by a thin film transparent filter 9 is decreased, and the focusing force of a focus lens 4 is reduced by reducing the coil current of the focus lens 4 depending on the decrease of the absorption current. As the focusing force of the focus lens 4 is decreased, the beam amount passing through an object diaphragm is increased, the beam amount to irradiate the thin film transparent filter 9 is increased subsequently, and the absorption current detected by the thin film transparent filter 9 is also increased. When the absorption current reaches to a specific value, the rise of the coil voltage of the object lens 5 is controlled to make the focus of the beams on the surface of a sample S. when the electron beam intensity is made stronger, the operation is carried out oppositely.

Title: Rare earth-iron-boron cast magnet
Inventor: TOKUNAGA MASAAKI
IPC: H01F41/02
Filed: 1988-09-19
Abstract: PURPOSE:To lower the temperature of a hot processing by adding at least one of Ti, P, La, Hy, and Zn besides a given amount of Cu to an R-Fe-B cast magnet having a predetermined composition. CONSTITUTION:The title magnet compsises 8-30% of R, 2-10% of B, 0.1-3% of Cu, and 3% or less of at least one of Ti, P, La, and Zn, with a residual part substantially comprising Fe, and is formed into a magnetically anisotropic one by hot processing. Ti, P, La, and Hg or Zn are to lower the temperature of hot processing and to obviously improve coercive force. The former effect is considered to originate for at least Zn from a fact that the melting point of Zn is low, i.e., 419 deg.C. In the cast magnet, Cu plays an important roll for manifestation of coercive force. When Cu, which has an about 1080 deg.C melting point, is added, it is distributed to an integrannular Nd rich phase and to a R2Fe14B main phase to more or less lower the temperature of hot processing for the R-Fe-B cast magnet.

Title: Blow molding method and mold apparatus
Inventor: KANEDA TSUTOMU
IPC: B29C49/48
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To prevent thickness reduction by controlling the wall thickens distribution of a deep drawing part without damaging appearance by constituting a part of the inner wall surface of a mold of the film releasable from the mold and bringing a molten parison into contact with the film and subsequently partially moving the central part of the film from the inside to the outside. SOLUTION: A slide core 4 is preliminarily ejected to the predetermined position inside a mold so that the internal space of the mold 1 surrounded by the inner wall of a mold main body part 2 and a film 5 becomes smaller than the size of a hollow molded product. When the slide core 4 is allowed to retreat after all of parts of a parison come into contact with the film 5 or the inner wall surface of the mold, the film 5 is pressed to the inner wall surface of the mold while the parison 6 holds the contact state with the film 5 by the air pressure inside the parison and the shape of the internal space of the mold becomes same to that of the hollow molded product. By adjusting the ejection quantity of the preliminarily ejected slide core, a molded product of which the corner parts have desired wall thickness is obtained.
