Title: Easily cuttable synthetic wood
Inventor: HONDA TAKESHI
IPC: B29K103/00
Filed: 1985-12-06
Abstract: PURPOSE:To offer a synthetic wood such as a homogeneous wooden molded material or the like, which is provided with physical properties, substantially the same as wood, and extremely abundant in cutting property, by a method wherein the blending ratio of wood powder and expoxy resin, having grain sizes of a specified mesh is specified, and the composition of the wood powder and the epoxy resin is molded under pressurizing and heating. CONSTITUTION:A composition, consisting of wood powder and epoxy resin, which are having grain sizes of 40 mesh or more and the blending ratio thereof is 95:5-50:50, is pressurized and heated to mold, whereby a easy-cutting synthetic wood, having the finishing density of 0.4-1.1, is obtained. In case the wood powder occupies 95 parts or more in the blending ratio of the wood powder and the epoxy resin, the adding effect of the epoxy resin can not be realized, on the contrary, in case the same is 50 parts or less, the material will never show wooden feeling and the workability is deteriorated since it is too hard. The finishing density of the molded material depends upon the throwing amount of the material into a mold upon molding, however, in case it is 0.4 or less, the strength of the material is not sufficient and, on the contrary, in case the same is 1.1 or more, the material becomes too heavy and the workability thereof is deteriorated. The synthetic wood, thus obtained, is comparatively light in weight, abundant in resistance to abrasion, excellent in workability and the cost is inexpensive.

Filed: 1994-10-05
Abstract: PURPOSE: To distinctly discriminate data of a running train form other data from other producing sources by fetching electric field intensity measured data of a radio wave emitting from the running train into noise and/or oscillation measured data. CONSTITUTION: A measuring device B for measuring noise and/or oscillation and another measuring device A for measuring electric field intensity are arranged together, and respective measured data are transmitted to a computer C. The measuring device A is constituted of a two-system receiving circuit including two directional antennas having a range of radio waves emitted from a train classified by train running direction. In this case an electric field intensity level gradually increases as the train approches, reaches a peak between an antenna axis line and a measuring point front, and thereafter decreases rapidly. Data of the running train can be discriminated from the other data of other producing sources by recording the data and a level fluctuating curve of a noise and oscillation trapezoid in parallel.  Furthermore, when a trigger level is provided in one of measuring levels, a data recorder can be operated only at the time when the train passes.

Abstract: PURPOSE:To prevent a depletion layer from reaching a substrate and increase a punch-through voltage by a method wherein the one conductivity type region is formed in the other conductivity type high impurity concentration region which is formed from the surface of the other conductivity type layer of a diode. CONSTITUTION:A P<+> type anode layer 5 of a diode 12 is not formed directly in an epitaxial layer 7 but formed in an N<+> type layer 10. The N<+> type layer 10 is formed by ion implantation and diffusion and has a surface concentration of 10<16>-10<17>/cm<-3> which is higher than the impurity concentration of 10<15>cm<-3> of the epitaxial layer 7. The anode layer 5, which is formed simultaneously with source/drain layers 1 and 2 has an impurity concentration of 10<19>-10<20>/cm<-3>. When the reverse voltage is applied between the P<+> type anode layer 5 and an N<+> type cathode layer 6, a depletion layer is prevented from reaching a substrate 8 because the N<+> type layer 10 is provided so that punch- through at a low voltage can be avoided. The same structure can be obtained by employing an N-type substrate and the reversal conductivity types.
