Title: Propulsion accelerator for gulping wave making resistance waves disturbing advance of hull of ship using said waves
Inventor: TOYOSHIMA KANEHITO
IPC: B63H11/02
Filed: 1985-04-04
Abstract: PURPOSE:To reduce the resistance that prevents the advance of a hull, apply strong energy to the water obtained by gulping wave making resistance waves from the stem using the resistance, to increase the propulsion force by pressurizing the water and jetting it from the stern. CONSTITUTION:The water and air with the energy that rushes in from only inlet ports 1 of the stem at almost the same speed as a ship are divided into two by central longitudinal tip protruded line 2 of the inlet ports 1 and are guided to two irregular type tip reduction pipes 3. The air is exhausted outside from an exhaust pipe 8 and the water is sucked by a pair of high speed large-scale propeller axial flow pumps 4. The water exhausted by the pumps 4 is set in high speed flow and high pressure in order of pipes 10, intermediate pump 11, pipes 12, and pressurization pumps 13. This water is jetted into the sea from a pair of stern injection ports 5 and the reaction force and the propulsion force of the conventional propeller 6 are combined, then the advance of the ship is set in high speed. In this case, a part of injected water becomes the reaction force that floats the stern and the other part is useful to disconnect the wake 15 of the propeller screw 6.

Title: Branch location storage system of digital computer
Inventor: YAMANISHI ASAO
IPC: G06F11/36
Filed: 1980-05-29
Abstract: PURPOSE:To effectively utilize the branch locations of all branch instructions in spite of the case in which programs run away just prior to detection of a fault by storing the branch locations of all the branch instructions with respect to the programs under operation when the fault occurs. CONSTITUTION:When the programs of a program storage memory 3 are executed, and a branch instruction 4 is executed, its branch location address is stored in the branch location storage memory 5 of the memory 3. Therefore, even if there are many branch instructions in the programs, the branch instrucions 4 and a branch location storage memory 5 exist in a pair and therefore all the branch locations are stored. Hence, branch locations of all the branch instructions are known with respect to the programs under operation when a fault occurs, and are effectively utilized for fault analysis and program testing.

Abstract: PURPOSE:To obtain a vermin-controlling material capable of continuously developing excellent vermin-controlling effect over a long period, having high safety and formable to arbitrary size and shape, by sandwiching a vermin-controlling component between plural sheet materials, at least one of which is a fibrous material. CONSTITUTION:A vermin-controlling component (e.g. pyrethroid, carbamate or organic phosphorus compound) is scattered or applied to a fibrous material and then covered with the same fibrous material or other sheet material (e.g. paper, cloth, synthetic resin sheet, foamed sheet or carbon fiber). The obtained laminate is hot-pressed at 100-200 deg.C to obtain the objective vermin-controlling material. The fibrous material can be produced by mixing 80-40wt.% cellulosic fiber with 20-60wt.% thermoplastic fiber (e.g. low-melting polyester or polyethylene) and spinning the mixture in the form of a sheet having an areal density of 10-100g/m<2> and a thickness of 1-10mm. The falling-off and scattering of the controlling component from the sheet material can be prevented by using the above fibrous material as an essential component of the sheet material.

CONSTITUTION:Preparing a wafer consisting of an N-substrate layer 9, a P<-> layer 4 of a buried layer is formed after forming a P-well layer 8. After the entire surface is covered with a nitride film, RIE of anisotropic etching is performed, thus forming a side wall 23 made of an oxide film on the side surface of a poly Si layer 7 covered with an element isolation insulation film 6 and an oxide film 22. Since the dimension d2 of the side wall 23 at the part covering the substrate is equal to the thickness of the first nitride film, it can be controlled by this thickness. Next, etching is performed by means of a photo resist pattern 24. After phosphorus treatment, an oxide film 25 is formed on the surfaces of the poly Si layer 7, N-layer 3 and drain N-layer 10. Finally, a side wall 26 is formed on the surface of the poly Si layer 7 covered with the side wall 23 and the oxide film 25 by RIE.
