Title: Fresnel lens sheet and transmission screen
Inventor: TAKAHASHI KATSUNORI
IPC: G03B21/60
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To obtain uniform brightness on a screen by connecting shortest focus of Fresnel lens at a specified distance from a center of the lens. SOLUTION: This Fresnel lens sheet 1 is used in a combination with a lenticular lens sheet for a transmission type screen, and the shortest focus fmin of the Fresnel lens is connected at a distance R from the center. The distance R from the center for the shortest focus fmin ranges 0.05h to 0.5h, wherein (h) is the height of the screen. When the distance R is smaller than 0.05h, the focus is included in a hot band region so that the effect of the lens is not obtd. If R is larger than 0.5h, the peripheral part of the Fresnel lens gives a short focus, which increases the loss in light quantity and causes coloring.

IPC: G03B42/04
Filed: 1992-07-13
Abstract: PURPOSE: To make it easy to handle the computing radiography reader by providing the auto reader which supplies a film cassette to the reader and receives the cassette from the reader. CONSTITUTION: The auto reader receives a stack of palettes 10 on a platform 78. Each palette 10 positions a cassette 62 containing a photosensitive element to be read on it including the photosensitive element. The platform 78 is moved up and down by an elevator 80 to position the palette 10 at a read position, where the element in the cassette 62 is read. Four right and left pins 58 engage the opening part 54 of the palette 10 at the read position and supports the palette 10 independently of the platform 78. The operation is started from the bottom palette 10, which is set at the read position. The palette 10 having the cassette 62 which is already read is removed while it is at the bottom of the stack and another palette 10 is at the read position.

Title: Conductive optical waveguide
Inventor: NORO TAKANOBU
IPC: G02B6/08
Filed: 1986-08-08
Abstract: PURPOSE:To reduce the number of processes, production cost and size by inserting metallic conductors into gaps formed among many fiber strands. CONSTITUTION:Flux consisting of many fiber strands and the metallic conductors 3 inserted into the gaps formed among the fiber strands is treated by thermocompression bonding or heat wire drawing/thermocompression bonding to set up a conductive metal wire on a fiber convergent type optical waveguide 5 along its axial direction. Thus, the optical waveguide 5 can be provided with both functions, i.e. optical waveguide and electric propagation. The fiber strands are joined with the conductors 3 on portions having no relation to the optical waveguide functions of the cores 1 and the clads 2 of the strands to prevent optical waveguide 5 from adverse influences to the optical waveguide functions. In addition, electricity and light can be transmitted only by pressing light emitting elements 6 against the optical waveguide 5 or connecting respective conductive parts mutually. In case of integrating small chips with high density, the chips can be easily set up and highly integrated and the cost and size can be reduced.

Abstract: PURPOSE:To improve the write reliability by making a re-transmission request to a transmitter side when occurrence of a write error is detected at a point of time of writing data to a memory and repeating the sequence to write the data to the memory again till the data are written correctly. CONSTITUTION:A CPU 1 of a receiver side equipment checks an error of each of frame data received via a modem 8 by a prescribed method and makes a frame re-transmission request to the transmitter side when an error of one frame or over takes place when data are written in a RAM 3. The transmitter side sends only the re-transmission request frame to be received again. Then the similar processing is repeated and when all frames are received correctly, the reception of the page is finished. Since a re-transmission request is made even on the occurrence of a write error to the RAM 3, the write reliability is improved.
