Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To make it possible to secure sufficient performance, reliability in an optical communication circuit without increasing a light emission quantity of a light-emitting element emitting an optical signal, by making nearly half or above of the light quantity of the optical signal emitted from an end surface of an optical fiber reach a light-receiving element with the optical signal emitted from the light-emitting element. SOLUTION: A first optical signal L1 is made incident on a luminous flux branch film 6 in an S polarization state. A laser diode 3 is arranged on a semiconductor substrate 1 so that the first optical signal L1 becomes the S polarization state for the luminous flux branch film 6. Then, the majority of the light quantity of the first optical signal L1 emitted from the laser diode 3 are reflected by the luminous flux branch film 6 to be 90 deg. deflected. A second optical signal L2 is emitted from the end surface of the optical fiber 11 to arrive at the luminous flux branch film 6 through a lens 8. Thus, the luminous flux branch film 6 makes nearly half or above of the light quantity of the second optical signal L2 emitted from the end surface of the optical fiber 11 reach a photodiode 4.

Title: Electron microscope image record reproduction method
Inventor: KATO TAKAYUKI
IPC: G06T1/00
Filed: 1986-12-25
Abstract: PURPOSE:To make it possible to reproduce an electron microscope image of an excellent observability, by determining the reading condition depending on the intensity of fluorescence radiated from a two-dimensional sensor. CONSTITUTION:The electron beams permeated through a sample are accumulated and recorded in a two-dimensional sensor to accumulate the electron energy, and then, a light radiation is given to the twodimensional sensor to release the stored energy as lights, which are detected photo-electrically to get image signals. When the electron microscope image is reproduced depending on the image signals, the intensity of the fluorescence radiated from the two-dimensional sensor is measured when the electron beams are stored and recorded in the two-dimensional sensor, and the reading condition and/or the image processing condition when the radiated lights are detected are determined depending on the measured fluorescent intensity. Since the reading condition can be set in an optimum condition responding to the storing and recording condition to the two-dimensional sensor, the electron microscope image of an excellent observability and a high picture quality can be reproduced.

Filed: 1997-11-04
Abstract: PROBLEM TO BE SOLVED: To form images through a method of sublimation transfer as it is without forming any dye receptacle layers by forming at least the dye acceptor surface of a dye acceptor sheet consisting principally of polyvinylchloride resin with polyvinylchloride containing plasticizer. SOLUTION: Upon manufacturing a dye receptacle sheet 1 being useful to card base material or the like from polyvinylchloride in accordance with an ordinary method, a plasticizer is contained in at least the dye acceptor surface. A quantity of the plasticizer use is 0.1 or 10 pts.wt. per 100 pts.wt. of polyvinylchloride for forming the dye acceptor surface; in particular, in the rang of 3 or 5 pts.wt. As a quantity of the plasticizer is too small, a dyeing property becomes insufficient with respect to sublimate dye. On the other hand, as it is too much, the dye acceptor surface is short of the rigidity and becomes flexible, as a result, malfunction transfer takes place such that the dye layer 2 of a thermal transfer sheet A is transferred as it is during thermal transfer, or oozing can occur in printing images at its preservation, resulting in forming no clear images undesirably.
