Title: Laser beam diffraction type apparatus for measuring particle size distribution
Inventor: MATSUI MASAMI
IPC: G01N15/02
Filed: 1988-12-29
Abstract: PURPOSE:To enable preparation of a sample of the concentration being suitable for measurement by a method wherein an undiluted solution of the material to be measured and a diluted solution thereof are prepared in first and third tanks respectively and these solutions are injected partially into a second tank during a period of measurement. CONSTITUTION:An undiluted solution of a material to be measured is held in a first tank 8 and a dispersive medium solution to be a diluted solution in a third tank 13, and moreover, a sample matched with an apparatus is held beforehand in a second tank 9. When a pump 4 is operated with second and third stop valves 7 and 11 opened, the sample in the tank 9 is sent to a flow cell 1 and made to circulate between the same and the tank 9. Thereby the sample of the tank 9 is subjected to irradiation by a laser beam from a laser beam applying unit 2 and diffraction corresponding to a particle size distribution occurs. In the case when the concentration of the sample is too high, for instance, in this constitution, the stop valve 11 is closed and the dispersive medium solution in the tank 13 is sent into the tank 9 through the flow cell 1. When the stop valve 12 is closed subsequently, the solution in the tank 9 is agitated sufficiently and the sample of the concentration being suitable for an apparatus is sent into the flow cell 1.

Title: Image communication method
Inventor: OYAMADA MASAICHI
IPC: H04N1/32
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To attain efficient transmission by allowing a transmitter side to send contour blocks with error correction coding and to send non-contour blocks with error detection coding and allowing a receiver side to reproduce frames through interpolation when any error is detected in a non-contour block. SOLUTION: A contour block sorting device 13 stores one pattern of a received original image and discriminates the image whether or not it corresponds to a contour block in the unit of coded blocks and generates a contour discrimination table and provides an output of the table to a communication control section 4. The control section 4 stores the contour discrimination table from the sorting device 13 and applies error correction coding to the contour discrimination table to generate a transmission frame and provides an output of the frame to a modulator 6. Upon the receipt of coded data from a Huffman coder 3, a number representing a position is added to the data and an error correction coder 16 codes the resulting data to generate a transmission frame and provides an output of the frame to the modulator 6.  Upon the receipt of data of a non-contour block from the coder 3, a number representing a position is added to the data and an error detection coder 5 codes the resulting data to generate a transmission frame and provides an output of the frame to the modulator 6.

Title: Water jet propulsion device
Inventor: NOMURA SHINPEI
IPC: B63H11/113
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To prevent propulsion devices from colliding with each other by absorbing dislocation in parallel movement, in two water jet propulsion devices jointed for the parallel movement. SOLUTION: A water jet propulsion device obtains propulsion force by jetting sucked water from an injection nozzle 2. Adjacent steering nozzles 10, 11 of two propulsion devices are connected with an air-cylinder-shaped link 22. The respective steering nozzles reciprocate in the same direction by hydraulic cylinders 13, 14, and 15, 16. Ports corresponding to each set of the hydraulic cylinders are connected to each other through safety valves 50, 51. At the time of reciprocation, if parallel condition of the steering nozzles 10, 11 is broken, the piston 27 of the link 22 moves, and air in the air cylinder and a cushioning material function as dampers. In such a case as one of the hydraulic pumps is stopped, large operational dislocation is generated between the steering nozzles 10, 11. The link 22 ensures a minimum distance between the steering nozzles 10, 11, and avoids a collision.  Excessive pressure generated in the hydraulic piping of a failed hydraulic system is released from the safety valves 50, 51.
