Title: Alkali titanate-whisker and production of the same
Inventor: NAGAI KUNIHIKO
IPC: C30B29/62
Filed: 1990-10-06
Abstract: PURPOSE:To prepare a thick and long alkali titanate whisker capable of exhibiting a sufficient strength when used for FRP/FRM by adding a compound containing Fe or Cr to TiO2 powder and subsequently subjecting the mixture to a hydrothermal reaction in an alkali solution. CONSTITUTION:A compound containing Fe or Cr is added to TiO powder and then the mixture is subjected to hydrothermal reaction in an alkali solution to provide the objective whisker. The whisker is an alkali titanate whisker comprising a main component of formula M2Ti6O12 (M is alkali metal) and Fe or Cr in an amount of 0.1-10wt.% based on the main component. The above production process and the raw materials to be used therein are hardly different from those in the conventional hydrothermal process, and the process can be performed using conventional installations at a low cost. Since the whisker has a similar length and much larger diameter as compared with the whisker by the conventional process it is particularily well suited for use as a tensile- strength reinforcement for FRP/FRM.

Title: Plastic sealing member
Inventor: KURAMOCHI EIJIRO
IPC: F16J15/10
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To temporarily fasten a seal member to a sealed part simply by arranging dimples on a surface opposed to at least the sealed surface at a prescribed clearance. SOLUTION: In an annular main body 1, dimples 2, 2a are arranged on a surface opposed to a sealed part at a prescribed clearance. The dimples 2, 2a are fanned on a cross section recessed in a semi-spherical shape. A depth having a prescribed distance is formed between an outer peripheral surface of the main body 1 and the dimple 2a of a bottom surface side. An elastic sealing member S formed in such above constitution is fitted into a recessed groove 4 formed around a hole of a machine parts 3, the back surface of the main body 1 is lightly push-pressed from an arrow F direction. In this time, the dimple 2a arranged on the bottom surface side of the recessed groove 4 is push-pressed, its circumferential edge 2b is deformed so as to enlarge toward an outside, and then air in the dimple 2a is delivered.  When push-press force is eliminated, the dimple 2a is restored in an original condition by elastic force of the elastic sealing member S, and thereby, the inside of the dimple 2a becomes negative pressure, and the seal member S is absorbed in the recessed groove 4.

Title: Developing system for vector font
Inventor: KASAHARA TATSUO
IPC: B41J2/485
Filed: 1990-10-09
Abstract: PURPOSE:To prevent the quality of a character from being deteriorated when variable power is applied by correcting the position coordinates of a vector font in a dictionary so as to keep the stroke width of the perpendicular part of the font constant. CONSTITUTION:The linear part YLo(longitudinal line and lateral line) in the vector font is remarked, and the variable power is applied as correcting the position coordinates of the font so as to keep the stroke width of the linear part constant in spite of the position of the line. Thereby, the character after the variable power is multiplied so as to uniformalize the stroke width of the linear part as the whole character. Thence, it is checked whether or not each node of the vector font forms the connection point of a curve and a straight line from vector font data, and when the node is the connection point, the position coordinates of the control points P2, P5 of the curve are corrected so as to locate the control point of the curve connected to the node on the extension of the straight line passing the node. As a result, it is possible to obtain a magnified/reduced character with high quality in which the stroke width of a curve part can be maintained equally to that of a linear part after variable power, and the curve part is connected to the linear part smoothly.

Title: Manufacture of transparent columnar ice
Inventor: TAKAHASHI HISAJI
IPC: F25C1/24
Filed: 1987-10-27
Abstract: PURPOSE: To facilitate making of transparent pillar-shaped or bar-shaped ice by a method wherein a screen base having leg parts mounted on the top surface of a mesh is placed on the bottom part of an ice making can and tubular bodies with the upper ends thereof under the surface of ice making raw water are arranged erected at a part near the wall of the ice making can on the screen base to accomplish ice making work while the ice making raw water in the tubular bodies is circulated to be renewed. CONSTITUTION: When an ice freezing layer reaches a cylinder 3, ice making raw water in the cylinder 3 also forms an ice freezing layer on the internal wall surface of the cylinder 3. While the ice freezing layer grows, the ice making raw water in the cylinder 3 is always renewed to the water with a lower concentration of salts of impurities and a dissolved gas just as the ice freezing layer on the wall of the ice making can 1 by a convection of the ice making raw water 8 which is caused by the ascending of air bubbles blown into the ice making raw water 8 from a drop tube 2 through an interval between the upper end of the cylinder 3 and the surface of the ice making raw water 8 and a space at a lower part of a plane 6 of a mesh of the screen base 4.  Thus, the ice freezing layer forms an ice freezing layer of transparent pure water and the growth of the transparent ice freezing layer by the pure water is continued to the end. As a result, the ice frozen in the cylinder 3 is turned to the transparent ice formed from the pure water.

Abstract: PURPOSE:To manufacture an optoelectronic integrated circuit containing a semiconductor laser which is not ristricted by a resonator length by a method wherein, when at least one of the resonator end surfaces of the semiconductor laser is formed, a groove surrounding the semiconductor laser is formed and a metal film is deposited over the whole surface of a substrate and then the metal film is removed. CONSTITUTION:A P-type GaAs buffer layer 11, a P-type Al0.3Ga0.7As cladding layer 12, a P-type GaAs active layer 13 and an N-type Al0.3Ga0.7As cladding layer 14 are formed on a semi-insulating substrate 10 by molecular beam epitaxial growth and AuGe/Au is evaporated to form a cathode 15 of a semiconductor laser. Then a groove is formed around the resonator end surface of the semiconductor laser and the semiconductor laser by etching and, after that, metal 20 is evaporated over the whole surface. As the metal 20 is removed by anisotropic ion beam etching except the semiconductor part, the metal 20 is left on the side wall of the resonator end surface of the semiconductor laser 1 and serves as a reflective film coating and also shuts off the leakage of a light to electric elements and the like. Therefore, when a planar type optical integrated circuit is produced, the area of the chip is not ristricted by the resonator length of the semiconductor laser.

IPC: B22D11/05
Filed: 1989-10-19
Abstract: PURPOSE:To enable stable operation without inducing bulging and break-out in the steady shifting stage by shifting short sides under condition, in which shifting velocity at lower end part of each short side is slower than that at upper end part of each short side in the steady shifting stage. CONSTITUTION:At the time of enlarging or reducing width of a cast slab 4 by shifting the short side 1 in a mold during continuous casting, condition of the short side 1 in the mold is divided into three steps of front inclining stage, steady shifting stage and rear inclining stage. A cast slab 4 in the mold is thermally shrunk at the time of shifting from upper part to lower part and the absolute quantity of thermal shrink age is affected with the width of mold. Therefore, in the case of parallel shifting in the steady shifting stage, if the parallel shifting is large, air gap is developed be tween the short side in the mold or large strain stress to the side face at the short side of cast slab in the mold is given. Therefore, in the steady shifting stage of the short side 1 in the mold, each short side is shifted under condition, which the shifting velocity Vl at the lower end part of short side is slower than the shifting velocity Vu at the upper end part of short side so as to always become inclination of the short side 1 in the mold corresponding to the absolute quantity of thermal shrinkage to the cast slab in the mold.

There are two pieces of the grooved parts and they are intersected crosswise each other. Then the paste spreads over the whole bottom face of the chip component. Moreover, respective groove parts have further deep grooves 5 at their pointed ends. Since the paste gathers well in these deep grooves, overflow of the paste from the recessed part is suppressed.
