Patent JP-H037694-A (JP)
Title: Yacht with engine
Inventor: KOBAYASHI KAZUO
IPC: B63H9/00
Filed: 1989-06-06
Abstract: PURPOSE:To decrease the sailing resistance of a vessel when it moves in the sailing mode, i.e., when the propeller is accommodated, by interlocking the rise/fall of the propeller with opening/closing of lid plates, and thereby enclosing a propeller accommodating chamber with the lid plates when the propeller is in accommodation. CONSTITUTION:When a propeller shaft 28 to which a propeller 30 is secured, is pulled up into a propeller accommodating chamber 32 by turning a handle 38, lid plates 34a, 34b are turned through links 42a, 42b round hinges 36a, 36b to shut the opening of the propeller accommodating chamber 32, which causes being flush with the undersurface of the hull 10. When the handle 38 is moved downward, the lid plates 34a, 34b open interlockedly, and the propeller shaft 28 tilts down through a universal joint 26. Now the propeller 30 secured at the foremost protrudes at the undersurface of the hull 10 and is rotated by an engine 22 to generate the propulsive force. This decreases the sailing resistance of the vessel when it moves in the sailing mode.

Title: Video signal synthesizing device
Inventor: NAKAGAWA TATSURO
IPC: H04N9/75
Filed: 1988-06-09
Abstract: PURPOSE:To extract a character from a video signal including the character and to synthesize other video signal by reading the video signal written in a video memory with the timing of the horizontal and vertical synchronizing signal of a second video signal including a character and synthesizing it with the timing of the character pulse signal. CONSTITUTION:First color information signals R1, G1 and B1 are A/D-converted with the timing of first horizontal and vertical synchronizing signals HD1 and VD1, written into a video memory 6, read with the timing of second horizontal and vertical synchronizing signals HD2 and VD2, D-A-converted and second color information signals R2, G2 and B2 are outputted. Next, a character pulse generating circuit 12 generates a character pulse signal YS corresponding to the character part from a second video signal. A video signal synthesizing circuit 11 converts the second color information signal to a composite video signal and the second video signal is synthesized by the timing of a character pulse signal YS. Thus, without using a special signal such as a sub-code, the character is extracted from the video signal and can be synthesized with the video signal, which becomes the background.

Filed: 1991-05-17
Abstract: PURPOSE:To detect the liquid level in a narrow space or under high temperature by directing an opening of a curved waveguide which opens slantwise to the liquid surface, and projecting ultrasonic waves. CONSTITUTION:A waveguide 3 penetrates a side face 8a of a high temperature liquid material tank 8, then curves downward at 3b at right angles. A front opening part 3a of the waveguide is directed with predetermined angles to the liquid surface 9 of a molten liquid material 9 in the tank 8.

Abstract: PURPOSE:To attain the discrimination of a faulty location in a short time while applying a fault search by applying loopback only to a test signal inserted in an idle time slot of a multiplex signal line so as to remain a multiplex signal in service. CONSTITUTION:When a multiplex signal A is fed to a test signal insertion/ detection circuit 2 and a test signal insertion section 3, the insertion section 3 inserts a test signal T obtained from a test circuit 5 via a signal line 6 into an idle time slot. A loopback command circuit 8 selects loopback circuits 10-1-10-n of unit circuits 1-1-1-n sequentially via control lines 13-1-13-n. The circuits 10-1-10-n apply loopback only the signal T in the signal A of the multiplex signal line 12 to a multiplex signal B of a multiplex signal line 11 through the selection. A test signal detection section 4 detects the signal T from the line 11 and sends it to the circuit 5 via a signal line 7. The circuit 5 collates the pattern of the inserted signal T with the detected signal T and discriminates the presence of a fault in the unit circuit provided with a corresponding loopback circuit in detecting the bit error.

Title: Cooling device of particulate material
Inventor: SUZUKI TAKESHI
IPC: C04B7/47
Filed: 1982-08-17
Abstract: PURPOSE:To efficiently cool clinker by a structure wherein a stepped part is formed in a grating bed in its low temperature zone and cooling water is fed to clinker layer near the stepped part. CONSTITUTION:The cooling water supplied by a pump 36 oozes out through porous members 32 and 33 into the clinker layer on a lower step grating bed part 21. The clinker falling down from an upper step grating bed part 20 is turned upside down and mixed with the previously fallen clinker at the stepped part 19. Concretely, the clinker, which was located at the upper layer in the upper step grating bed part 20 and has comparatively high temperature, is placed at the lower layer in the lower step grating bed part 21. Said high temperature clinker placed at the lower layer in the part 21 comes into contact with the oozed-out cooling water and is efficiently cooled by the latent heat of evaporation of the cooling water and at the same time the clinker placed at the upper layer is cooled through the mutual heat conduction between both of the clinkers, resulting in improving the cooling effect as a whole.

Filed: 1989-06-07
Abstract: PURPOSE:To reduce the saving/restoring overhead of a context at the time of interruption processing while suppressing the increment of hardwares by storing the context of a part of an interruption level defined by a processor in the processor. CONSTITUTION:When an instruction circuit means 18 instructs a frame number selection control means 27 and an instruction execution unit 1 to restore a context from a memory area, the means 27 instructs a selection means 25 to select a frame number for a system mode. A program for saving/restoring contexts extracts a context from the memory in accordance with a context storing address 21 and loads the context. Consequently, overhead saving/restoring the context at the time of generating an interruption can be removed.

Title: Book character reading method
Inventor: KOGA YUKIO
IPC: G06K9/36
Filed: 1990-06-01
Abstract: PURPOSE:To accurately read the characters of the character strings set rectangularly to the boundary between the opened pages of a book by applying the specific preparatory processing to the image of each character string and reading the characters based on the processed image of each character string. CONSTITUTION:In regard of the preparatory processing applied to a character string image bent at the periphery of a boundary from an image input device, each point on a reference line set in the lengthwise direction of the image of an oblong character string area circumscribed to each character string is orthogonally projected on the extended line of a rectilinear part of the reference line. Then each segment connecting the points adjacent to each other at the orthogonal projection is corrected in the magnifying direction so that the length of the segment is set at the value accordant with the reference line obtained before the orthogonal projection. At the same time, these segments are moved so as to be adjacent and connected to each other from the rectilinear part of the reference line. Such preparatory processing is applied to the image of each character string and the characters are read based on each corrected or normalized character string image. Thus it is possible to accurately read the characters of the character string images which are bent at the periphery of the boundary between the opened pages of a book.
