Inventor: KOUDA HIKARI
IPC: C30B29/22
Filed: 1992-04-16
Abstract: PURPOSE:To grow a stabilized beta-phase single crystal by judging the grown crystal as the beta phase when a seed crystal in contact with a melt is not cracked at the time of pulling up the single crystal of beta-BaB2O4 from the melt using a beta-phase seed crystal. CONSTITUTION:A raw material of BaB2O4 is melted, then a beta-BaB2O4 single crystal is used as the seed crystal, and the single crystal is grown by the pulling method. In this case, the grown crystal is judged as the beta phase when the seed crystal in contact with the melt is not cracked and as the alpha phase when not cracked. The alpha phase is discriminated from the beta phase or vice versa when the seed crystal is brought into contact with the melt, and a single crystal with the beta phase stabilized is grown.

Title: Controlling transferred method for printing density of thermal trnasfer recording
Inventor: GENNO HIROKAZU
IPC: B41J2/36
Filed: 1990-05-11
Abstract: PURPOSE:To prevent the lowering of transferred printing density to a desired transferred printing density value or less by performing correction for lowering transferred printing density while driving a heating resistor on the basis of a density characteristic table showing the relation between a transferred printing density value and the pulse length of an applied signal prepared when no heat is accumulated on a thermal head. CONSTITUTION:A density table is obtained by driving the heating resistor on a thermal head of constant temp. based on the time when no heat is accumulated on the thermal head to calculate the pulse length of a signal having to be applied in order to obtain desired density. Further, by changing a desired density value and temp., some kinds of density tables to constant temp. are obtained. When printing (75-gradation and 10-gradation transferred printing) of constant density is carried out using this density table, a desired transferred printing density value is obtained immediatly after transferred printing is started but, thereafter, the transferred printing density value gently becomes high and reaches a saturated state from the point of time when the thermal head reaches an almost steady temp. state to be prevented from becoming the desired transferred printing density value or less. Therefore, only correction lowering density may be carried out.

Title: Trespasser detector using optical fiber
Inventor: NAKAMURA MASAKAZU
IPC: G01V9/00
Filed: 1985-06-07
Abstract: PURPOSE:To detect trespassers with high sensitivity by causing a change by one of a pair of optical fibers in accordance with the physical change due to trespass to a detection area and separating the other from the part of the physical change due to trespass. CONSTITUTION:The coherence light led from a laser light source device by an optical fiber is branched into an optical figer 1b for detection and an optical fiber 1c for reference by a branching device. The fiber 1b is directly brought into contact with a detection area 6 and is stored in a groove provided in the internal bottom part of a recessed supporting body 7 fixed to the area 6. If a trespasser appears in the area 6, a building member in the area 6 is changed physically to deform the fiber 1b. In this case, the optical fiber 1c which is insulated from the supporting body 7 by materials which absorb easily the physical change and is laid in a vessel 9 is difficult to deform because of materials 10. Consequently, fibers 1b and 1c are considerably different from each other in deformation to change interference fringes formed on a coupler. Thus, the trespasser is detected with a high precision.
