Title: Measuring device of particle size distribution of granular material suspended in fluid
Inventor: KATOU SHIGERU
IPC: G01N15/02
Filed: 1983-02-23
Abstract: PURPOSE:To measure precisely a particle size distribution in the natural state in on-line by providing a photodetector array in a duct where a suspension is flowed. CONSTITUTION:A measuring light and the photodetector array are provided so as to face the duct where a liquid suspended with particles is flowed. The output of a photodetector group 20 of this photodetector array is given to a binarizing circuit group 22 through an amplifier group 21 and is made binary. This output is converted to a number of pulse trains, which is proportional to the duration of the binary signal, by a pulse converting circuit group 24, and these pulse trains are counted and stored in a counter group 26. If binary signals are generated simultaneously from adjacent photodetectors, the existence of a particle is detected; and if the photodetector in the end of the photodetector array is operated, it is removed from the object of counting. The counted result is sent to a microcomputer 40, and the particle size distribution is displayed on a display device 60. Thus, the particle size distibution in the natural state is measured precisely in on-line.

Title: Formation of circuit
Inventor: KUNIMATSU SHUJI
IPC: H05K3/10
Filed: 1989-02-08
Abstract: PURPOSE:To facilitate the formation of circuits without defectives and waste powder by a method wherein adhesive agent is applied in a circuit pattern on a board, and a specified conductive powder is attached thereon, and the attached powder is subjected to a conduction treatment after excessive powder is removed. CONSTITUTION:Adhesive agent is applied in a circuit pattern on a board 1 to form an adhesive agent pattern. Next, conductive powder capable of self- diffusing and joining is scattered on the pattern and made to adhere. Then, after the adhesive agent becomes hardened, the board 1 is put upright and vibrated to remove excessive powder in the part other than the patter. And, as the powder has a property of self-diffusion, it grows to be in an integral structure with time, but in this case, when the powder is pressed with a pressure roll or like, the grains of powder area spread to be brought into contact with each other and accelerated to be in an integral structure of electrical conduction to form a circuit 4. By this constitution, a defective circuit does not occur, a manufacturing process can be remarkably shortened and moreover a conductive material can be used without waste.

Title: High density building board and its production
Inventor: SHINBA EIJI
IPC: B29K101/10
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To obtain high density, high strength, and high rigidity by mixing specified amounts of crushed inorganic fibers having a specified average aspect ratio and a binder resin and molding the mixture in a specified specific gravity range. SOLUTION: A glass wool W is supplied continuously on a belt conveyer 1 and crushed finely to adjust the aspect ratio of the finally obtained fibers to be 3-125. A molding compound obtained by uniformly mixing 50-90 pts.wt. of the crushed glass wool and 50-10 pts.wt. of a binder resin is molded appropriately. When the specific gravity of the mixture is below 0.5, strength is not enough in terms of the entanglement effects of straight line-shaped glass fibers, when it is 1.5 or greater, a high pressure press is required; therefore the specific gravity is adjusted to be 0.5-1.5. The crushed particles are dispersed uniformly in the binder resin to improve strength and rigidity.
