Title: Backup device for computer
Inventor: SUETOMI AKIRA
IPC: G06F11/20
Filed: 1979-12-12
Abstract: PURPOSE: To prevent paper from being torn by storing and holding output data of the reference speed of computer in a normal state for a back device for the computer for a paper machine, etc., even when the computer is abnormal and by performing manual operation.  
     CONSTITUTION: Backup device 7, while outputting interruption signal (k) for a diagnosis of a computer to CPU1, receives analog reference signal (b) and performs A/D conversion and, when diagnostic response signal (l) arrives, compares it with a value stored at the last timing. As a result, when it is equal to the last memory value, this value is D/A-converted and outputted as automatic speed reference signal (m) to paper machine controller 5. When they disagree, on the other hand, the current A/D-conversion data is held and signal (m) is left as it was. Further, if diagnostic interruption response (l) is not made to diagnostic interruption (k), signal (m) stays as it was. Consequently, even if the computer is abnormal, output data of the reference speed when the computer is normal is recorded and held and manual operation is started, so that the tearing of paper is prevented.

Abstract: PURPOSE:To obtain a correcting liquid which has high dissolving power with a toner resin and decreases the spreading of a solvent except in the image part to be corrected by consisting said liquid of diethylene glycol dialkyl ether and dialkyl phthalate. CONSTITUTION:The result of the inspection made to ascertain the quality possessed by a reproducible original relating to the requirement for the prohibition of the solvent spreading in the part except the image part to be corrected indicates that said paper is lipophilic to solvents such as benzene and toluene having high oiliness but is repellent to water. The solvent which can be mixed with water, i.e., the solvent having a hydrophilic property is adequate for the above- mentioned liquid. The solvent which meets the above-mentioned requirement and can satisfy correcting power and safety as well as the diethylene glycol dialkyl ether which is optimum as the correcting liquid for the toner image. The diethylene glycol dialkyl ether and dialkyl phthalate are used in combination in order to prevent the resticking of the toner by early drying.

Filed: 1986-07-08
Abstract: PURPOSE:To improve both recording density and recording capacity by arraying plural light spots on a track where the tracking parts and data recording parts are formed alternately and also setting the arraying spaces of those light spots so that they are positioned on the tracking parts. CONSTITUTION:For a data recording format, the tracking parts 4 and data recording parts 5 are arrayed on the same straight line to form a track DTL in a data recording area 6 on an optical recording medium. These parts 4 are set so that the length of the part 4 is equal to l/2 toward a tracking line TL and the distance between centers of adjacent parts 4 set at l respectively. While the parts 5 serve as blank parts held between parts 4 with the length of the part 5 set equal to l/2 toward the track DTL. Thus a data track DT is formed like a broken line. As a result, the data writing/reading jobs as well as the tracking job are attained just with a single line.

Title: Logic circuit converting system
Inventor: KUROSAWA YUICHI
IPC: G06F17/50
Filed: 1988-06-30
Abstract: PURPOSE:To produce an efficient circuit having less redundancy by performing the materializing process of a functional module in a logic composing process by taking the connecting relation of the module into account. CONSTITUTION:A circuit realizing system selecting means 13 checks the connecting destination of the input signal of a functional module in a logic circuit and selects appropriate one out of such materializing systems of the functional module that 'the corresponding functional element in a cell library is assigned', 'a gate cell is assigned after the functional module is expanded in an AND/OR gate and optimized', and so forth. A circuit conversion executing means 14 converts a circuit in accordance with the materializing system selected by the means 13. Thus the materialization of a functional module is performed by paying attention not only to the function held by the module, but also to the connecting relation of the module. Therefore, an efficient circuit having less redundancy can be produced.

Title: Sentrifugal separator
Inventor: MIYAZAKI HAJIME
IPC: B04B3/00
Filed: 1977-12-29
Abstract: PURPOSE: To improve the dehydratic performance by rotating a press member provided in a separator body at a speed different from that  of a basket also provided therein, so that a compression force is generated between the basket and press member, which compression force is applied to a material to be dehydrated.  
     CONSTITUTION: A material to be dehydrated is fed from the upper portion of a feed pipe 5 into a bottom portion 2c of a basket 2. When  a motor is then driven, rotary shafts MS 1 , MS 2  are rotated at different speeds and the material is accelerated in the circumferential direction from the bottom portion 2c and lower portion 2a of the rotating basket 2 so as to be moved gradually in the upward direction along the inner surface of the lower portion 2a thereof. While the material is thus  moved in the upward direction, it is dehydrated by the centrifugal force. The material is further upwardly moved along an upper portion 2b of the basket 2, where a compressing force is applied thereto since the rotational speeds of the basket 2 and press member 6 are different and since the press member 2 is deformed substantially elliptically. The material is thus further dehydrated.

Abstract: PROBLEM TO BE SOLVED: To provide a picture collating device which considerably shorten the processing time of picture collation and prevents erroneous erasing of linear patterns generated at the time of correcting a picture to be collated. SOLUTION: This picture collating device extracts ruled lines from an input picture read by an image scanner or the like (step A1) and compares these extracted ruled lines with those extracted from a reference picture to examine rough pixel correspondence between the input picture and the reference picture (step A2). Next, the device divides the input picture into small areas and retrieve an area having the closest pattern from positional vicinities on the reference picture calculated by the examined correspondence to perform mapping (step A3). This mapped picture is divided into small areas, and each small area is moved to obtain a picture most coinciding with the reference picture (step A4), and finally, the difference picture between this obtained picture and the reference picture is outputted (step A5).

Abstract: PURPOSE:To position parts with a high precision in the front and behind, and right and left directions and for directively by floating parts and opening and closing a centering member through collar members and link members in this state by an alternating magnetic field to position parts in a prescribed position. CONSTITUTION:When parts are placed in a set centering position, the whole of a head is allowed to fall just under parts 14, and air is sent to a holding tube 3 to keep parts 14 suspended, and when an alternating voltage is applied to an electromagnetic coil 4, collar members 5 and 6 are attracted to and repulse each other by the generated alternating magnetic field and are oscillated vertically. That is, when they are attracted to each other, centering plates 13A are operated outward through link members 10A by the falling operation of the member 5 to extend the gap between centering plates 13A, and plates 13B are operated inward by the rising operation of the member 6 to narrow the gap between plates 13B. When they repulse each other, plates 13A and 13B are operated reverse; and thus, pairs of plates 13A and 13B hold and release parts 14 alternately in the front, the rear, the left, and the right directions, and this operation is repeated correctly and precisely to position parts 14.
