IPC: B63H21/17
Filed: 1989-02-14
Abstract: PURPOSE:To suppress the hull size becoming too large and enhance the propelling performance by arranging outboard a plurality of fins for control of hull motion and attitude, fitting each fin with a propelling machine consisting of a superconductive motor, and providing applicability of outboard machine even to a large-sized vessel. CONSTITUTION:A plurality of fins 1 for control of hull motion and attitude are arranged at both sides of the rear part of a large-sized vessel. A propelling machine 2 consisting of a superconductive motor is installed at the outer end of each fin 1. Propelling machine 2 in the same construction as above is arranged also inside the rear part of the vessel. Propellers a1-a3 are installed at the tail of each propelling machine 2 so as to constitute an outboard propulsive device. This provides applicability of outboard propelling machine even to a large-sized vessel, allowing increasing the number of propelling machines without enlarging the hull, which should lead to enhancement of the propelling performance to a great extent.

Title: Storage device
Inventor: SUGIMOTO AKIRA
IPC: G11C11/413
Filed: 1982-03-02
Abstract: PURPOSE:To access an address adjacent to an accessed address at a high speed, by connecting a shift register between an address decoder and a memory array. CONSTITUTION:When array type data are successively accessed, the first address of the array type data is housed in an address buffer 1 and decoded by an address decoder 2. The accessing to the first address is performed by operating a shift register 6, sending the signal of an address signal output line 3 as it is to an address signal input line 7, and latching the signal. When the next address of the array type data is accessed, the accessing is performed whithout the address buffer 1 and address decoder 2, by shifting the content of the shift register 6 in the higher rank direction and sending the content to the address signal line 7. Thereafter, the same operation is repeated. However, when a different data are to be accessed during the accessing process, the signal of the address signal output line 3 is sent to the address signal line 7 as it is, but the shift register 6 does not latch the signal.

Title: Document print control system
Inventor: MATSUYA MASUO
IPC: B41J21/00
Filed: 1989-02-13
Abstract: PURPOSE:To accurately alter document format information by an operator and to avoid a wasteful operation by obtaining printable document format information from a designated sheet size and designated printing format information if the document can not be obtained in the sheet when document information is printed according to a printing formed designated by an operator. CONSTITUTION:A menu of a printing format is displayed on a CRT screen of a CRT display 108. When the format is designated by an operator according to the menu, printable numbers of characters and lines are calculated from information of designated sheet size, character interval, line interval, and compared with a document format belonging to the document information. Here, if the designated format is set larger than the values of the numbers of the lines and characteristic obtained according to the calculation, whether an automatic correction is possible or not is judged. If the automatic correction is impossible, a message of the gist that it is impossible to print with excess numbers of characters and lines and designated format is displayed on the screen of the CRT 108. Thus, when the operator alters the format, a wasteful operation and consumption of time can be prevented.

The pitch interval between the hole parts 5a is so set that the hole part is located within the same field of view of, e.g. an optical microscope. At this time, since the hole part 5a wherein the substrate member 4 is exposed is formed in the vicinity of a scratch 6, the scratch 6 and the exposed part of the substrate member 4 are contained in the same field of view of the optical microscope. The minute comparison of both parts can be performed with the optical microscope.
