Title: Signal reflection type communication equipment
Inventor: SAKAGAMI YUZO
IPC: H04B10/11
Filed: 1986-03-31
Abstract: PURPOSE:To attain the satisfactory communication of a signal reflection type by using a posture information setting means which sets the posture information of a signal reflecting member in response to the reception level and a drive energizing means which energizes a drive source means of a drive mechanism in accordance with said posture information. CONSTITUTION:The elevation angles of an optical signal transmitter 100 and an optical signal receiver 300 are set so that the optical axes of the transmitter 100 and the receiver 300 are turned to the center of a reflecting plate 200 of a reflecting plate unit 200. Under such conditions, a posture setting unit 310 connected to the receiver 300 has the maximum optical signal. The posture information on the plate 210 is set and converted into radio signals to be transmitted through a transmission antenna Ant1. Receiving the radio signals through a reception antenna Ant2, the unit 200 performs the posture control of the plate 210 based on the posture information included in the radio signals. In such a way, the posture of the plate 210 is controlled and therefore the direct optical signal 110 received from the transmitter 100 is reflected by the plate 210 and received accurately by the receiver 300 in the form of a reflected optical signal 120.

Filed: 1989-03-27
Abstract: PURPOSE:To reduce the height-directional width and save the installation space and to eliminate the need for attaching and detaching operation by locking a copy receiver to the top surface of a cassette tray while the copy receiver is moved down. CONSTITUTION:When the cassette tray 2 is expanded, the cassette tray 2 is released from being engaged with the copy receiver 15 by a lock member 19 and the copy receiver 15 moves up the position where the copy receiver 15 is in level with a paper discharge opening, thereby receiving copies.

IPC: B32B27/36
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To obtain a thin, soft film which cuts off near UV rays well, and is bloomingless. SOLUTION: A basic composite film consists of an UV cut-off layer and a migration obstructing layer which are laminated on both side of the UV cut-off layer.

The migration obstructing layers are formed from an oxygen-containing resin, and at least one of them is laminated by coextrusion with the UV cut-off layer. Moreover, in a practical composite film, on one side of the basic composite film, for example, polyolefin inner skin layer and/or on the other side, for example, a nylon outer skin layer are laminated. The adjacent two layers of one of the two composite films are coextruded or lamination-bonded with an adhesive polymer placed between them.  Therefore, the following is made possible: ultraviolet transmittance 20% or less, visible light transmittance 80% or more, no blooming of UV absorbing agent, no deterioration of packaged contents after a long period, and durable transparency and oxygen barrier properties.

Abstract: PURPOSE:To measure the distribution of the height of the surface of a body in atmospheric air without contact and without destruction, by forming the image of the surface of a sample, placing a pinhole in the image surface, and selectively receiving light from a part having a specified height. CONSTITUTION:A parallel beam from a laser 1 is reflected by a surface 8 of a cube mirror 2, converged by a lens 4, and irradiated on the surface of a sample 5. The reflected light from the surface of the sample 5 is made to be a parallel beam by a lens 4, and reflected by a surface 9 of the mirror 2. The image is formed at the position of a pinhole 11 by a lens 10. The light passed the hole 11 is detected by a light detector 12. In this case, when the height of the surface of the sample 5 is located at the position of the focal point of the lens 4, the image of the laser spot formed on the hole 11 is small. Then the mirror 2 is vibrated and rotated, and the laser beam is scanned on the sample 5. When the laser beam scans the part where the surface height of the sample 5 agrees with the focal point position of the lens 4, a pulse shaped output appears at the output terminal of the detector 12.
