Abstract: PURPOSE:To perform an insertion edit processing on an existing document with simple operation by dividing a form into areas based on marking information on the form obtained from a luminance information processing means and position information obtained from a control means, and performing the edit of a document by using those area information. CONSTITUTION:The device is equipped with a print means 1, the control means 2, an optical sensor 3, the form 4, the luminance information processing means 5, an area division means 6, and a document edit means 7. The control means 2 outputs the position of the optical sensor 3 on the existing document, and the luminance information processing means 5 converts the position information obtained from the optical sensor 3 to the marking information. The area division means 6 finds an area position marked on the existing document from the marking information and the position information obtained from the control means 2 by using a division method, and outputs it to the document edit means 7, and limits the document edit nd processing of a user to a marking area with the means. In such a way, it is possible to perform insertion edit or overwrite to the existing document having a complicated format with the simple operation without necessitating the setting of the complicated format on the document to be edited.

Title: Photosensitive composition
Inventor: TERADA KAZUTOSHI
IPC: C08F261/04
Filed: 1990-07-04
Abstract: PURPOSE:To greatly improve poor strength of an unexposed blank plate and an exposed resin letterpress plate by using a photosensitive composition comprising a polyvinyl alcohol having an average molecular weight of >=4000 and a compound having an radically polymerizable ethylenically unsaturated double bond and a photopolymerization initiator. CONSTITUTION:When the average molecular weight of the polyvinyl alcohol is too low, an effect for enhancing the strength of the printing plate is lowered, so it is preferred to select the resin having an average molecular weight of >=4000, further, >=6000, especially, >=8000, and most preferably, >=10000. Any ethylenically unsaturated compound capable of undergoing radical polymerization by the photopolymerization initiator, such as polyvinyl alcohol type polymers, can be used and the ones good in compatibility with the photopolymerization initiator,k such as polyethylene glycol acrylate, are used. The photopolymerization initiator to be used is embodied by benzophenone and the like, thus permitting the strength of the printing plate material to be remarkably enhanced as compared with the conventional ones, while moderating deterioration of development speed.

Title: Dynamic pressure bearing made of ceramics and manufacture thereof
Inventor: NAKAHARA MASAHIRO
IPC: F16C33/24
Filed: 1994-07-29
Abstract: PURPOSE:To reduce a wear amount, improve the reliability and prolong the service life by forming a dynamic pressure bearing made of ceramics by using ceramics having a specified Young's modulus and average crystal particle size and specifying surface coarseness of the bottom of a dynamic pressure generating groove. CONSTITUTION:A dynamic pressure bearing made of ceramic is formed of ceramics 1 having a Young's modulus of 300GPa and an average crystal particle size of 0.5mum or more and surface coarseness of the bottom of a dynamic pressure generating groove is set to 1mum or less. When the Young's modulus is 300GPa or less, a dynamic pressure effect by the high-precise dynamic pressure generating groove 2 is not stably produced occasioned by deformation due to an applying load. When the average crystal particle size is 0.5mum or less, the edge of the dynamic pressure generating groove 2 is formed in a too acute state and cutting wear of a mating material is increased. When surface coarseness of the bottom of the dynamic pressure generating groove 2 exceeds 1mum, a holding force for a fluid film, such as lubricant, between a dynamic pressure bearing and a mating material is decreased, contact between the dynamic pressure bearing and the mating material is apt to make and wear is progresses. High reliability and a lengthened life can be brought.

Abstract: PROBLEM TO BE SOLVED: To provide a safe extremely low temperature fluid feeding device which does not have danger such as an explosion in an extremely low temperature fluid container. SOLUTION: When the connected state between an extremely low temperature fluid container 4 and a transfer cable 2, and between the transfer cable 2 and a cryostat 1, is confirmed, a control means 7 lights up an operation available display lamp 5a of a pressurization device 5, and judges whether an extremely low temperature fluid is fed to a specified level in the cryostat 1, or not, based on a liquid level detection signal from a liquid level sensor 9. When the liquid level reaches the specified level, the control means 7 performs a motion to stop the feeding of the extremely low temperature fluid, and when the liquid level has not reached the specified level, the control means 7 judges the presence/absence of the opening/closing of an electromagnetic switching valve 3.  When the valve is under a closed state, the control means 7 indicates to the electromagnetic switching valve 3 to open a passage, and when the electromagnetic switching valve is under an opened state, the control means 7 gives a pressurization indication to the pressurization device 5.
