The slurry in which e.g. 3wt.% red oxide is added into the slurry having been supplied into the first cylinder paper machine, is supplied into the second cylinder paper machine with one cylinder. While color cake is scooped up from the cylinder by the rotation of a felt belt, the green plate having been made by the first cylinder paper machine is moved onto the felt belt, and the color cake is brought in contact with the under surface of the green plate, thereby forming the laminate green plate with 5mm thickness. After the laminate green plate has been compressed e.g. under 45kgf/cm<2> pressure, it is cured naturally for three weeks and further is dried.

Abstract: PURPOSE: To contrive the increase in he lifetime of a semiconductor laser device by interposing a semiconductor layer having low thermal expansion coefficient as compared with a semiconductor substrate between the first clad layer or an active layer and the substrate, thereby largely decreasing the stress of the active layer.  
     CONSTITUTION: There are sequentially grown N type Ga 1-u Al u As buffer layer 9, N type Ga 1-y Al y As clad layer 2, Ga 1-x Al x As active layer 3, P type clad layer 4, P type cap layer 5, and N type current control layer 6 on a substrate 1. In this configuration, the stress of the active layer with respect to the AlAs mixed crystal ratio (x) of the layer 3 can be so reduced as not to occur deterioration in case that the energy gap difference between the active layer 3 and the clad layers 2, 4 is 0.25∼0.40eV by selecting suitably the value of the AlAs mixed crystal ratio (u) of  the buffer layer 9. Thus, it can absorb the adverse affect of the thermal expansion  coefficient of the substrate 1, and can effectively alleviate the stress applied to the  layer 3 by the substrate 1.

Filed: 1982-06-30
Abstract: PURPOSE:To reduce a feeding resistance, by contacting such a quality material part as being large in a friction factor and installed in a feed roller, with a sheet in time of feeding the sheet through this roller, while contacting another material part lesser in the friction factor with the sheet this time when no sheet is fed. CONSTITUTION:A feed roller 4 delivering a sheet 2 one by one is formed by the way of projecting both a rubber-make feed roller 41 and a plastic auxiliary roller 21 being somewhat smaller in diameter than the said roller 41 upward from a square hole 3' made up in a sheet loading block 3. And, the feed roller 41 is secured tight to a shaft 20 while the auxiliary roller 21 is rotatably attached to the shaft 20, regulating the thrust direction by means of a grip ring 22. With this, if a flat part (a) of the feed roller 41 comes beneath the sheet loading block 3, a peripheral surface part (b) of the feed roller 41 conveys the sheet 2 forward. At this time, the auxiliary roller 21 rotates in accord with rotation of the sheet 2, reducing a feed resistance. Likewise, in time of stopping the shaft 20, the auxiliary roller 21 comes into contact with the sheet 2, thus the feeding resistance is reduced.

Abstract: PROBLEM TO BE SOLVED: To enhance workability by laying a mat having the properties of weakening rain force by swelling by soil water and of granulating soil in muddy water, on the leveled ground. SOLUTION: A planting vegetative mat 1 is constituted by layering a net 2 and a corrosive water-weakening cloth piece such as a thin cotton lap 4 to which a high polymer coagulator as a soil particle coagulator is stuck. Next, the mat 1 is laid on the leveled ground 9 created on a riverbed or the like by putting the lap 4 below, and the leveled ground 9 as vegitative bedrock is protected by the net 2. Next, the coagulator is swollen by soil water, and at rainfall time, rain is weakened by the net 2 and the lap 4, and soil in muddy water generated in the leveled ground 9 contacts with the coagulator, and is condensed and granulated, and only transparent water is flowed down. Since the coagulator can endure several time rainfalls, a seedling and roots 12 or the like can be planted and grown in planting holes formed in the mat during that time.  Therefore, the bare land can be protected just after the ground is leveled, and muddy water pollution of revers or the like can be prevented.

Title: Method for conveying and/or melt-kneading powder
Inventor: NISHIGORI TAKUYA
IPC: B29B7/48
Filed: 1997-04-17
Abstract: PROBLEM TO BE SOLVED: To reduce adherence of powder to a screw spiral groove or conveying member by adding metallic salicylate compound to the powder. SOLUTION: Metallic salicylate compound is added to powder by directly mixing or adding it into the powder. To raise density as it is conveyed by a screw, the screw is disposed so that a ridge of the spiral groove of the screw is not brought into contact with a trough of the spiral groove of the other screw at a powder supplying position. An effect of kneading is increased by applying pressure to the powder by making the trough of the groove shallow as the conveyance is advanced. And, as the conveyance of the powder is advanced, the powder is softened and kneaded while raising a temperature. And, an embracing member of the screw is heated and set to that the temperature is low at the powder supplying position and becomes higher as the conveyance is advanced. As the metallic salicylate compound, ditertiary chromium butylsalicylate complex or ditertiary zinc butylsalicylate is used.  They each has an effect of antistatic control agent.
