Title: Image input device
Inventor: SUDO YOSHIHIKO
IPC: H04N1/19
Filed: 1994-12-15
Abstract: PURPOSE: To reduce moire to a degree of not affecting the image quality with a reduced space. CONSTITUTION: An image of an original 2 is projected on an image sensor 33 by an image forming lens 13 to read the image. In this case, since the magnification of the image forming lens 13 is smaller than (1-1/(Ld+1)<1/2> , where L is a required resolution on the original 2 and (d) is a diameter of pupil of the image forming lens, a moire erasing light transmission member 23 is arranged removably on an optical axis OA between the image forming lens 13 and the image sensor 33. As a result, the member 23 is contained in the small space and driven easily and the cost is reduced.

Title: File access control system
Inventor: SUZUKI HIROYUKI
IPC: G06F21/62
Filed: 1988-12-12
Abstract: PURPOSE:To prevent extent information in file from being destructed and to rapidly check the validity of an access request by executing an access request to a file based upon the specification of a using right ID. CONSTITUTION:Since extent information 15 used by an access request from an access request part 11 is determined by capability being a using right identifier (ID), it is unnecessary for an access request part 11 to directly specify the extent information 15 at every access request. Since an address space A1 in which the access request part 11 is driven is different from an address space A2 is which the extent information 15 is developed, access to the extent information 15 is impossible in a virtual storage space even in the case of a privileged program in which the access request part 11 uses a specific key. Since the extent information 15 can be prevented from being destructed in error by the misprogram of an access request part 11, a check for the validity of the extent information 15 can be omitted.

Title: Release agent for fire spread preventive coating
Inventor: FUJITA MICHITOMO
IPC: H02G1/12
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To obtain a release agent which, when applied to the outer peripheral surface of a covering for fire spread prevention of an electric wire or cable, swells and softenes the coating in a short time without corroding the copper member of the wire or cable by using an org. solvent as the main ingredient and by incorporating a self-adhesive and a rust preventive into the same. SOLUTION: The org. solvent used here is one having a solubility parameter of 8-13 or is mixture of two or more such a solvent. A combination of benzyl alcohol with 10wt.% N-methyl 2-pyrrolidone is pref.; the combination exhibits swelling and softening effects more than benzyl alcohol alone. The self-adhesive encloses components remaining after the permeation of the solvent into the covering, causing the components to adhere to the periphery of the covering and preventing powdery components, etc., from scattering. The self-adhesive is a high-viscosity resin latex, such as an acrylic resin latex or an EVA latex. A rust preventive, such as benzotriazole or 2-mercaptobenzothiazole, is used in an amt. of 1-10wt.% of the solvent.

IPC: G01N1/28
Filed: 1989-12-05
Abstract: PURPOSE:To prevent breakage and a leak from being caused at the joint part between a steel tube and a stopper plate by specifying screw pitch and screw thread height when engaging the screw of the stopper plate for pressure sealing with the screws of both tube ends of the steel pipe threadably and fixing them. CONSTITUTION:When the test tube 2 and stopper plate (pot lid) 1 for pressure sealing are fixed, the internal screw 14 and external screw 15 are formed according to JIS B0207 (meter fine thread), but the internal screw pitch is 0.5-1.0mm. Consequently, the minimum thickness of the thread-cut part is reduced to secure the strength of a screw part 13. Then the thread height of the internal screw 14 or external screw 15 is made 0.05-2.0mm larger than the standard of JIS B0207. Further, the screw part 13 is coated with an adhesive of epoxy two-liquid mixing type, etc., sufficiently and the screws are engaged. Consequently, the gap 16 between the screw top and bottom is eliminated to securely eliminate a leak in the joint part between the pot lid 1 and tube 2 at the time of a test.
