Title: Molded wood board
Inventor: HIGUCHI KOJI
IPC: B27N3/02
Filed: 1995-03-31
Abstract: PURPOSE: To enable a presentable decorative board without any recessed part in the decorative surface, based on a molded wood board as a material by mixing wheat bran generated at the time of flour manufacture into wood chips to be formed on a surface layer and molding this mixture. CONSTITUTION: A mixture of 90% of wood chip, 5% or less of wheat grain and 10% of wheat bran is prepared as a surface layer chip. Further, the mixture is molded under pressure to draw the wheat bran 2 into a space between the chips 1 as a stratified penetration. Thus any clearance is prevented from forming in an area between the chips 1. Consequently, the wheat bran 2 is positioned in such a manner that the a gap between the chips 1 is filled with the wheat bran 2, when the surface is finished by cutting at a position shown by a one- point chain line using a sanding technique, and a satisfactory surface smoothness is obtained. However, if wheat bran containing a large number of grains is used, a projecting part forms at spots on the surface due to the wheat grain as a cause for the formation.

An electric field is generated in a direction Y when the prescribed voltage is impressed to the electrodes 14, 15a and the refractive index is changed by a change in the electrooptic constant r22 of this time. The TE wave and TM wave sense the change in the refractive index of the reverse code at the same magnitude with respect to the waveguides 11 and 12 and, therefore, the switching action which does not depend on the polarized light is executed. The production of the waveguides is thereby facilitated and the optical switch having no dependency on the polarized light is obtd.

Abstract: PURPOSE:To suppress the resistance of a collector and to reduce the capacitance formed at a semiconductor substrate, in one transistor region, by providing a plurality of embedded layer regions having different concentrations. CONSTITUTION:The resistance of a collector and the capacitance between an embedded layer and a semiconductor substrate are factors for determining the performances of a transistor. The concentrations of the embedded layers determining said resistance and capacitance are located in the different regions. This property is utilized. Namely, the high concentration embedded layer 22 is formed in the region for determining the collector resistance. The low concentration embedded layer 12 is formed in the region for determining the capacitance at the semiconductor substrate 11. Thus the transistor, in which the collector resistance is small and the capacitance at the substrate is also small, can be formed.

Abstract: PURPOSE: To add an accurate amount of an inoculant to molten metal in the extremely short process of receiving the molten metal in a ladle by forcibly feeding the inoculant dispensed into a temporary holding tank to a molten column by compressed air.  
     CONSTITUTION: An electric motor 6 is driven to revolve a propeller shaft 5b so that a required amount of an inoculant P is transferred into a temporary holding tank 7. On the other hand, a ladle 1 which has received molten metal during this process displaces from the receiving position to the position shown by dotted lines, where it is supplying molten metal R into the receiving cup 2a of a mold 2. Upon completion of charging into the mold 2, the ladle 1 is returned to the receiving position, and begins to receive molten metal from a molten metal supply port 3a. At this time, if a solenoid valve 9 is opened within the receiving period after lapse of some time by timer operation, compressed air from a compressed air source 8 flows into the tank 7 for the inoculant P, then the inoculant P transfers into a force-feeding pipe 10, through which the inoculant P infilters the molten metal column flowing out from the port 3a into the ladle 1, and plunges into the molten metal of the ladle 1 by inertia, whereby the quick and sure dissolution of the inoculant P and its uniform rabbling are accomplished.
