Abstract: A process for the formation of an artificial seaweed bed comprises depositing a structure as an artificial fish reef in the sea. According to the present invention, the structure is made of a glassy material having a specific composition, or a surface of the structure is covered with the specific glassy material. The glassy material contains silicon in an amount of 30 to 70 wt. % in terms of SiO.sub.2. The glassy material further contains sodium and/or potassium in an amount of 10 to 50 wt. % in terms of Na.sub.2 O and/or K.sub.2 O. The glassy material furthermore contains iron in an amount of 5 to 50 wt. % in terms of Fe.sub.2 O.sub.3. All or a part of the iron is present in a ferrous state. The glassy material contains the ferrous iron in an amount of not less than 1 wt. %.

Abstract: A method for preparing foreign protein in yeast using an expression recombinant DNA comprising DNA encoding the serum albumin signal peptide adjacent to DNA encoding the foreign protein is disclosed.

Abstract: Novel signal peptides capable of functioning in yeasts have the amino acid sequence:Met-A.sub.1 -A.sub.2 -X-B-C-D-E-Fwherein A.sub.1 is a peptide chain composed of 1-3 amino acids each selected from the group consisting of Arg, Ser, Lys and His, A.sub.2 is a peptide chain composed of 1-3 amino acids, X is a peptide chain composed of 8-10 hydrophobic amino acids, B is Pro or Ser, C is Gly or Pro, D Cys, Ala, Leu, Ser, Thr and Val, E is Trp or Gln and F is Ala or Gly. DNA sequences coding for these signal peptides can be used for the secretory expression of heterologous proteins in yeasts.

Abstract: This invention relates to a method and apparatus for forming a glass container by a press-and-blow system wherein the glass container is provided with a reinforced inner surface. According to the inventive method, fuel gas or a gaseous boron or silicon compound is burnt or otherwise reacted inside a parison after the parison molded in the blank mold is transferred to the finish mold. The burning or other reaction of the fuel gas or gaseous boron or silicon compounds can be carried out just prior to the final blow-molding step in which the parison is blow molded into its final shape, simultaneous with the final blow-molding step, or just after the final blow-molding step. The apparatus of the present invention includes a finish mold provided with a blow head which includes a low selector valve. The low selector valve is open during combustion or other reaction within the parison and is automatically closed during the final blow-molding step by the pressure of the compressed air used in the final blow-molding.

Abstract: A glass vessel crusher including an external cylinder 1 and an internal cylinder disposed in the external cylinder, a glass-vessel crushing space A of ring shape in section being defined by the inner wall of the external cylinder 45 and the outer wall of the internal cylinder. At least one of the external cylinder and the internal cylinder is freely rotatable and is so designed that the glass-vessel crushing space is gradually narrowed along a direction from a glass-vessel throw-in side toward a fragment discharge side, and at least one of the inner wall of the external cylinder and the outer wall of the internal cylinder is provided with a spiral projection 57 extending into the ring-shaped glass-vessel crushing space.

Abstract: A setup condition recorder for a color scanner for reproducing a reproduction picture, wherein an original picture to be reproduced, secured to a picture mount means, is scanned by a pickup head to obtain a picture signal, and wherein an operational unit determines setup conditions for the color scanner from the picture signal, and the setup conditions are recorded on a recording medium by a recording unit.

Abstract: A method for controlling exposure light beams for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein a light beam is supplied to an acoustooptical deflector and is deflected thereby to obtain diffraction light beams which are incident to fixed light paths and are used for exposing a recording film, and wherein the diffraction light beams are controlled by varying a frequency of a supersonic wave supplied to the acoustooptical deflector so that each diffraction light beam may be or may not be incident to the respective light path.

Abstract: A color control simulator for a picture reproducing machine such as a color scanner and a color facsimile, wherein an input means such as a pickup head scans an original picture to obtain color separation picture signals which index a memory table stored in a memory to output first color-corrected color separation picture signals, wherein the first color-corrected color separation picture signals of the table are replaced with second color-corrected color separation picture signals which are output by a color control means such as a color controller and a key board, and wherein a display means displays colors corresponding to the color-corrected color separation picture signals fed from the memory. A computer controls the input means, the memory, the color control means, and the display means.

Abstract: A method for automatically determining the color control conditions such as a highlight point, shadow point, a gradation control, color correction, and so forth, for a picture reproduction for use in a picture reproducing machine such as a color scanner and a color facsimile, wherein an original picture is scanned photoelectrically to pick up color separation picture signal data of the primary colors. The signal data is classified into groups to obtain a distribution condition, and according to the distribution condition obtained the color control conditions are determined.

Abstract: A system for reproducing and recording a plurality of color originals is disclosed which simultaneously scans a series of sections of a scanning field in which there are disposed pictures having different characteristics and changing the set values of color separation and correction circuitry to compensate for these conditions or characteristics. The scanning process is synchronized with the selection of the suitable conditions of color separation and correction to correspond to the type of picture which is being scanned at any given or particular time.
