Title: Production of prepreg and apparatus therefor
Inventor: YONEMOTO KAMIO
IPC: H05K3/02
Filed: 1984-03-10
Abstract: PURPOSE:To promote impregnation well while expelling air bubbles in a base material and obtain a prepreg capable of forming laminated boards without causing voids, warpage nor torsion, etc., by applying ultrasonic vibration through a resin solution to the base material in passing the base material through the resin solution. CONSTITUTION:A base material 1 is passed through and impregnated with a resin solution 2 and dried to give a prepreg 3. In the process, ultrasonic waves from an ultrasonic generator 5 are applied through the resin solution 2 to the base material 1 while passing the base material 1 through the resin solution 2. The base material 1 is impregnated with the resin solution 2 while being passed through a resin tank 4 filled with the resin solution 2 and vibrated with ultrasonic waves from the ultrasonic generator 5. The impregnated material 1 is then led to a heating zone 6 by guide rolls 9 and dried to give the aimed prepreg 3.

Title: Paper sheet stacking device for feed paper of paper sheet printing machine
Inventor: KAJITA YASUKI
IPC: B41F21/00
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To install a paper sheet stacking table in shallow pits by making a stacking table formed into a U shape in front section and provided with plate-like parts projecting from the upper parts on both sides to the outside, and supporting the paper sheet stacking table by spherical bearings of beam-like supporting parts through the plate- like parts. SOLUTION: A paper sheet stacking table 12 having the U-shaped section is supported by spherical bearings 9 through plate-like parts 12a, and a spring is installed between a beam and the paper sheet stacking table 12 so that the paper sheet stacking table 12 may be brought in contact with a guide. To adjust the lateral position of the paper sheet stacking table 12, a motor, a gear, a screw shaft, and a lever are arranged on a supporting table extending from the beam 11, and connected to the paper sheet stacking table 12. Printing paper sheets are loaded on the paper sheet stacking table 12 by a hand lift, and the upper paper sheets are fed to a printing machine one by one after the lateral direction is adjusted. As the paper sheets are decreased, the paper sheet stacking table 12 is raised together with beams 10, 11 and the spherical bearings 9 by rising and lowering chains 7, 8. Since a table plate or a spherical bearing are not provided under the bottom plate 12b of the paper sheet stacking table 12 in this device, the depths of pits 21 can be shallowed.

Abstract: PROBLEM TO BE SOLVED: To prevent the locked state of an ink ribbon in a tape cassette from occurring and, at the same time, prevent a platen roller and a tape feeding roller from caving-in after they have been let aside for a long time. SOLUTION: This tape printer has a speed reducing gear 23 connecting with means 24-27 for transferring a tape and an ink ribbon, a releasing transmission gear 19 connecting with a printing head positioning means and planetary mechanisms 51 and 53 rotating about a motor shaft.

Then, the power transmitted to the releasing transmission gear 19 moves a head support 6 and a tape feed roller holder 12 through a releasing cam 18 and a releasing lever 17.  In other words, the ink ribbon, which is used for printing performed under the condition that no sagging of the ink ribbon is prevented, is immediately taken up to a ribbon take-up core and, under the condition that no printing is performed, the printing head is apart from a platen roller and a tape feeding roller from a tape holding- down roller.

Abstract: PURPOSE:To accurately measure wavelength dispersion characteristic by making an optical pulse signal transmitted through a wavelength selecting reflection film incident on a sample fiber and counting the delay time of the optical pulse signal emitted from the sample fiber as the function of the wavelength of an optical pulse. CONSTITUTION:The laser pulse generated from a laser pulse generation means 1 and made incident on an optical fiber 2 for Raman oscillation causes forward scattered light and the light of specified wavelength is reflected by the wavelength selecting reflection film on a light emitting surface and reversely transmitted in the fiber 2.

The light emitted from the fiber 4 includes the light of all the wavelengths generated by Raman oscillation, which is emitted with the lag of emission time caused by wavelength dispersion. The delay time of the light emitted from the fiber 4 is counted as the function of the time of the wavelength of the optical pulse by a delay time counting means 20, so that the wavelength dispersion characteristic of the fiber 4 is known.
