Abstract: PURPOSE:To prevent the scattering of the fibers constituting a mat, by superposing the mat and cloth both of which are impregnated with a reactive curable resin and winding the same around a steel pipe so as to turn the cloth to the outside. CONSTITUTION:A liquid reactive curable resin is sprayed to a mat 1 from a resin liquid spray nozzle 20 to be infiltrated therein. this mat 1 and the cloth 2 impregnated with the liquid reactive curable resin in a lower resin layer 10 are spirally wound around the outer periphery of a steel pipe or coated steel pipe 3 so that the cloth 2 is superposed on the outside of the mat 1. By this method, even when the bundling binder of the mat 1 is dissolved, the scattering of the fibers of the mat 1 can be prevented by the cloth 2 and a fiber reinforced resin coated steel pipe having excellent corrosion resistance can be prepared in a highly efficient manner.

Title: Silica gel aggregate and its production
Inventor: KATO HARUICHI
IPC: B01J2/28
Filed: 1993-11-08
Abstract: PURPOSE:To obtain a silica gel aggregate having sufficient adsorption/desorption capability. CONSTITUTION:A powdery silica gel and a powdery binder are mixed in dry process, a solvent is added into the mixture of the silica gel and the binder, then they are mixed or kneaded and solidified. Therefore only a very small area of the boundary of the silica gel is coated with the binder, but the narrow pores existing in the other area are not clogged. Thus, the adsorption/desorption function is kept in the most of the boundary of each silica gel, thereby the sufficient adsorption/desorption function is exhibited in the silica gel aggregate.

Title: Manufacture of liquid crystal polymer molded item
Inventor: SUENAGA JUNICHI
IPC: B29C45/03
Filed: 1989-10-25
Abstract: PURPOSE:To stably manufacture a precision molded item having a high weld strength and an excellent impact resistance by a method wherein injection molding is performed through a gate having the specified crosssectional diameter at the time of manufacturing a molded item having the specified weight out of resin composition, which is prepared by mixing the liquid crystal polymer with tetrapod-like whiskers. CONSTITUTION:At the preparation of resin composition by mixing liquid crystal polymer with tetrapod-like whiskers, the shape of the screw of a mixer, shearing speed at mixing, quantity to be processed and the like must be taken into consideration in order to suppress the breakage of the whiskers to minimum. In the case of the manufacture of a molded item having the weight of 1g or less out of said resin composition with an injection molder, it is necessary for employing a gate having the crosssectional diameter of 0.5mm or more. If the diameter is below 0.5mm, the tetrapod-like whiskers are broken during their passage through the gate, resulting in obtaining no satisfactory mechanical properties. The crosssectional form of the gate may well be elliptic, rectangular or the like and preferably circular. The preferable gate is one point gate for keeping away from the development of weld. Further, the injection molding is preferably performed under the conditions that the rotational frequency of the screw is set as slow as possible, the detention time is set as short as possible and the injection speed is set as slow as possible.
Patent JP-H02126488-A (JP)
Title: Disk device
Inventor: OKAMOTO YOJI
IPC: G11B33/08
Filed: 1988-11-04
Abstract: PURPOSE:To improve a vibration attenuation function and the impact resistance of a mechanical frame composed of a metallic substrate part and a non-metallic holding part by connecting the mechanical frame through a vibration damping member provided close to a supporting member with the supporting member. CONSTITUTION:When impact is applied in the directions of arrows A and B while a CD player is transported, a CD mechanical frame 1 vibrates in the directions of the arrows A and B. At this time, although a metallic substrate part 2 collides with a supporting member 5, the impact force never reaches a holding part 3 because of the interposition of a vibration damping member 4 between the holding part 3 and the supporting member 5. On the other hand, when the impact is applied to the CD player in the directions of arrows C and D, the CD mechanical frame 1 vibrates in the directions of the arrows C and D. At this time, although the metallic substrate part 2 collides with a cabinet 6, the metallic substrate part 2 never collides with the holding part 3. Thus, the vibration attenuation function and the impact resistance of the mechanical frame can be improved by providing the vibration damping member 4 close to the supporting member 5.

Title: Optical fiber gyro
Inventor: ASAMI EIICHI
IPC: G01C19/72
Filed: 1993-11-09
Abstract: PURPOSE:To stabilize the bias by thermally insulating an optical fiber coil from the outside. CONSTITUTION:In an optical fiber gyro having such structure as an optical fiber most sensitive to the temperature is secured to the fixing face 13 of optical fiber gyro and a protective cover 15 is applied to the optical fiber coil 12, other optical components 14, a light source 17, etc., the gap between the optical fiber coil 12 and the protective cover 15 is sustained in vacuum state 18 thus retarding transmission of the variation of ambient temperature to the optical fiber coil 12 through the protective cover 15. Since variation of ambient temperature is transmitted with a significant time lag to the optical fiber coil 12 or it is hardly transmitted, bias drift, i.e., so-called thermally induced drift, of the optical fiber gyro can be reduced significantly.

Filed: 1995-10-26
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of air-fuel ratio control by learning the deviation from a reference value of an air-fuel ratio feedback correction value in the specified idling range, renewing the learned result as a learning value of the invalid pulse length and storing it, and correcting the learned value on the basis of the differential pressure between fuel supplying pressure and intake air pressure. SOLUTION: When the specified idling state is judged by a control unit 12 during the operation of an internal combustion engine, learning of the invalid pulse length in the low pulse length range in which the fuel injection quantity change amount in relation to the change amount of the pulse length can not obtain linearity is performed. That is, the maximum value and the minimum value of the feedback correction factor α are input, and whether the mean value of α is approximately equal to the reference value (=1) or not is judged. When the judged result is YES, the status quo is maintained, on the other hand, when the judged result is NO, and when the mean value of α is larger than the reference value, the learning value TSL of the invalid pulse length is decrease-corrected to the lean side.  When the mean value of α is smaller than the reference value, the learning value TSL, is increase- corrected to the rich side.
