Title: Limited steering angle detection device of small ship
Inventor: TAKAHASHI HIROYUKI
IPC: B63H25/24
Filed: 1990-04-20
Abstract: PURPOSE:To make proper steering of a ship possible within an area in which turbulence does not take place by providing a sensor which detects turbulence of water flow on outer surface of a streamlined projecting parts on the bottom of the ship symmetrically right and left, displaying a signal detected by the sensor and watching the display. CONSTITUTION:A rudder 7 and a ballast keel which project downwards on the bottom of a ship body 1, are provided. For example, three metal detectors (sensor) 81-83 are arranged on one side of outer surface of the rudder 7 and the ballast keel 8. Then respective detectors 91-93 are pushed by water flow to made contact with sensors 81-83 and indicating lamps 64-66 are turned on through respective amplifiers 61-63, in normal sailing condition. When turning angle increases above a certain value and turbulence takes place on one side of outer surface, indication lamps 64-66 are turn off due to a cause that detectors 91-93 are pulled up outward side by turbulence and separated from sensors 81-83.

Title: Coupling method for photointegrated circuit
Inventor: HORIMATSU TETSUO
IPC: G02B6/26
Filed: 1980-07-31
Abstract: PURPOSE:To make it possible to attain coupling of less loss, by providing gratings to the parts of optical waveguides which are to be connected facing to each other. CONSTITUTION:The light 26 traveling through an optical waveguide 25 while repeating interface total reflection cannot be totally reflected when reaching an end part 27 but is radiated to the outside of the waveguide 25. Accordingly, making the end grating surfaces of two optical waveguides face to each other permits a bidirectional photocoupling to be obtained. As the grating degree lambda becomes thinner, even if the vertical coupling length l of the opposed surfaces is reduced, a photocoupling of substantially no coupling loss can be obtained if the depth d thereof is on the order of lambda/2.

Title: Thread generating method
Inventor: KUSABA TAKUO
IPC: G06F9/48
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for smoothly responding to a connection request from a client without allowing a server to waste a system resource. SOLUTION: A method for generating thread consists of next four means. The first means (S1) decides the number of null threads for the client within the server, the second means (S2) generates the thread, the third means (S4) assigns the client to the null thread and the fourth means (S5) counts the number of the null threads. These means generate a state where some null threads are always in stand-by for the client's connection request within the server. When the connection request comes to the server from the client, the server can assign the thread to the client. In addition the server does not have to always prepare threads for all the clients and can release a memory when the connected clients are few.
