Title: Manufacture of fiber reinforced resin foamed sheet
Inventor: KANAMORI ICHIRO
IPC: B29K105/04
Filed: 1990-06-22
Abstract: PURPOSE:To easily infiltrate highly viscous resol type phenolic resin composition solution in reinforcing fibers by a method wherein specified amount of polyoxyethylene-etherified castor oil is added as surface-active agent. CONSTITUTION:The loadings of polyoxyethylene-etherified castor oil are set to be 0.5-3 pts.wt., because, if the loadings are below 0.5 pts.wt. form stabilizing effect lowers and if the loadings exceed 3 pts.wt. impregnating effect lowers. By employing the polyoxyethylene-etherified castor oil as surface-active agent, favorable wetting to reinforcing fibers 4, uniform surface covering, compatibility to resol type phenolic acid and the like are realized. Since the polyoxyethylene- etherified castor oil is used as the surface-active agent for stabilizing form, the amount of infiltration and attachment of phenolic resin in and to glass fiber mat can be made larger, resulting in allowing to remarkably improve its impregnating properties and to easily manufacture fiber reinforced resin formed sheet excellent in strength.

Title: Treatment of looped steel wire material while conveying it
Inventor: FUJII IKUO
IPC: B65G47/22
Filed: 1981-10-19
Abstract: PURPOSE:To bring a looped steel wire material in uniform contact with treating liquid and to inhibit the formation of unevenness in a treated state, in treating the looped steel wire material with the liquid while carrying it with a conveyer, by vertically vibrating the chain rail of the conveyer to apply vibration to the steel wire material. CONSTITUTION:A looped wire material W is pickled with acid-pickling liquid 3 in a cell 1 for treatment such as acid-pickling, while being carried with a chain conveyer 2. A chain rail 4 for supporting the chain conveyer 2 is hence vertically vibrated at the outlet side 4' by the rotation of a sprocket 5, and the vibration is transmitted through the chain conveyer 2 to the looped steel wire material W. The acid-pickling liquid comes in sufficient contact with a loop-overlapping part, too, because of the vibration, so that the whole of the looped steel wire material is uniformly acid-pickled without the formation of unevenness in acid-pickling. This method is effectively applicable to treatment for plating the looped steel wire material, too.

Title: Measuring method for width of margin part and thickness of metal vapor-deposited film of metallized film for capacitor
Inventor: HONMA CHUICHI
IPC: H01G4/18
Filed: 1994-06-27
Abstract: PURPOSE: To obtain a measuring method by which the margin part of a metallized film and the film thickness of a metal vapor-deposited film are measured simply and precisely, and in which a mask plate is installed at the margin part of the metallized part, irradiation light is radiated in the width direction and transmitted light is received by a CCD camera. CONSTITUTION: An image in a part illuminated with a high-frequency fluorescent lamp 2 on a metallized film 1 for a capacitor is formed by a CCD camera 4 installed at its upper part, and it is detected as a luminance in the width direction. Light which is transmitted through a metal vapor-deposited part 7 is received weakly, light which is transmitted through a transparent margin part 1a is received strongly, and the light is used as a luminance signal in the width direction of the film 1. Since the transparent margin part 1a exists in the film 1, a blooming phenomenon is generated in the boundary between the metal vapor-deposited part 7 and the margin part 1a so as to be changed into a noise, and a precise detection becomes difficult.  When a mask plate 3 composed of a light reducing filter 8 used to shield illumination from the fluorescent lamp 2 is installed at the margin part 1a, the influence of the blooming phenomenon is removed, and the rise of the margin part 1a can be detected clearly.

IPC: B23P19/06
Filed: 1989-06-28
Abstract: PURPOSE:To perform stable tightening of screw irrespective of torque change in wide range by interrupting transmission of high-speed shaft due to increase of torque at the time of tightening after screw is seated by high-speed shaft, and tightening screw by a low-speed shaft via a one-way clutch. CONSTITUTION:While the screw mounted to a chuck 13 when it is tightened is not seated, a clutch 7 transmits power, and a main spindle 12 is rotated at a high speed to perform seating due to rotation of a high-speed shaft 4 via a gear 8 and an output shaft 9. When torque increases, the clutch 7 slides, speed is reduced, and the rotating speed of main spindle 12 becomes low-speed rotation of a low-speed rotary shaft 5, a one-way clutch transmits power to the output shaft 9 to rotate the main spindle 12 at high torque so as to tighten a screw. When the tightening is completed, load torque increases rapidly, load current of a motor 1 increases rapidly, and signals which are detected through a current transformer 16 and a differentiating circuit 17 increase. A switch 15 is turned off by a judgement control circuit 18, thereby completing the work.
