Title: Perfecting press
Inventor: MIYAGAWA AKIRA
IPC: B65H31/00
Filed: 1991-11-20
Abstract: PURPOSE:To enable perfect front operation on the front side of a printer and to make the printer small-sized and inexpensive by also using a manual paper feed port as a discharge port of printing paper subjected to double-side printing processing. CONSTITUTION:A manual paper feed port 4 is also used as a discharge port of printing paper subjected to double-side printing processing. As a result, an exclusive paper delivery part separate from the manual paper feed port can be dispensed with and, since the delivery of printed paper is also performed from the manual paper feed port on the front side of a printer by providing the manual paper feed port to the front of the printer, operability is improved and the peripheral space of the printer can be effectively utilized. Further, a mechanism is simplified and the body of the printer can be miniaturized and decreased in cost.

Title: Projecting type television device
Inventor: TSUKAGOSHI KAZUO
IPC: H04N9/31
Filed: 1989-12-21
Abstract: PURPOSE:To uniformize a color from the center of a cathode ray tube to its surrounding part and to expand the color reproduction range by providing a color selection means having a high reflectance with respect to the light of a wavelength less than 520nm in a projecting lens group arranged in front of the cathode ray tube. CONSTITUTION:When an electron beam is made incident in a phosphor 6 of a cathode ray tube 1, a light spectrum is generated. Light having a peak near a wavelength of nearly 600nm does not emitted from the cathode ray tube 1 depending on the transmissivity of a multi-layer interference filter 5. However, undesired light having its peak at a wavelength somewhat shorter than 500nm is emitted from the cathode ray tube and is made incident in a projecting lens group 2. Since a multi-layer interference coating layer 8 has a high reflectance with respect to a light whose wavelength is 520nm or below, the light whose wavelength is 520nm or below is not emitted from the lens group 2. Thus, only a green light having its peak around 545nm exists and the color purity from the center of the cathode ray tube to the surrounding part is improved.
