Title: Secondary cooling method of billet in continuous casting installation
Inventor: AOKI MASATO
IPC: B22D11/124
Filed: 1982-09-10
Abstract: PURPOSE:To inject uniformly mists to a billet without receiving the influence of a difference in head by mixing water and air to generate the mists, and injecting the mists through a supply main to the billet from injection pipes. CONSTITUTION:The water supplied from a supply pipe 29 and the air supplied from a supply pipe 25 are mixed with a mist generator 10, by which mists are generated. The mists are injected through a supply main 24 toward a billet 2 from injection pipes 8 provided among many rolls.

Title: Crystal growth method
Inventor: NAKAJIMA KAZUO
IPC: H01L21/208
Filed: 1985-07-17
Abstract: PURPOSE:To readily control the movement of solute element in growing liquid by contacting a source material, supplying an AC current between the source material and the liquid to generate heat, and dissolving the source material in the liquid. CONSTITUTION:An AC current is supplied from an AC power source S though carbon electrodes 13, 14 between a source material 12 and multi-element compound semiconductor crystal growing liquid 2 to heat the material 12. Then, the material 12 is heated in the state that the heat due to Peltier effect is partly added to the Joule heat due to the resistance of the material 12 itself. When solute element dissolved from the material moves in the solution to arrive at a grown crystal at this time, the movement of the element becomes only due to diffusing effect and convection effect, and an effect due to an electromigration is removed. Thus, the moving control in the liquid of the solute element can be facilitated.

Title: Optical head and its adjusting method
Inventor: TAKASHIMA MAKOTO
IPC: G11B7/135
Filed: 1993-06-29
Abstract: PURPOSE:To provide a small-sized optical head having a short optical path by adjusting the focus by moving a collimator lens. CONSTITUTION:A luminous flux 12 emitted from a semiconductor laser 1 and made incident on a diffraction grating 2 is diffracted into zeroth-, first-, and higher-order diffracted light rays and the diffracted light rays are made incident on a collimator lens 3. The lens 3 converts the light rays into a parallel luminous flux and the parallel luminous flux is condensed through a lens 14 after passing through a beam splitter 4. By observing the light spot 12i condensed at the position where a microscope is fixed, a holder 13 is moved and adjusted in the direction B of the optical axis of the microscope so that the diameter of the spot 12i becomes the smallest. When the adjustment is made, the luminous flux 12 emitted from the laser 1 is condensed onto a disk through a objective lens of the microscope and the reflected light of the condensed light is focused on first and second focal points 16a and 16b. Therefore, the positional deviation between the light source 1 and collimator lens 3 can be corrected with high accuracy by forming a reference light spot by making a highly accurate parallel luminous flux coming from the outside of an optical head and adjusting the light spot formed by the light from the light source by moving the collimator lens on the basis of the position of the light spot in such a way.
