Title: Transmission type screen
Inventor: MIYATAKE YOSHITO
IPC: G03B21/62
Filed: 1986-09-22
Abstract: PURPOSE:To reduce difference in luminance due to the position of the whole of a picture plane, by setting a prism element so that a projecting beam of light is total-reflected on a second surface in a forward direction after transmitting refractably a first surface, and changing the beam of light immediately after total reflection, so that it becomes a divergent beam of light within a plane perpendicular to the ridge of a prism element. CONSTITUTION:When the projecting beam of light is made incident on a first translucent plate 19 from an oblique direction, the projecting beam of light transmits refractably the first surface of the prism element 21, and is total-reflected on the second surface, and transmits refractably the first translucent plate 19, and transmits refractably the Fresnel lens 22 of a second translucent plate 20. As for the beam of light total-reflected on the second surface of the prism element 21, projection on the inside of a plane perpendicular to the ridge of the prism element 21 becomes a divergent beam of light, and the projection on the inside of the plane in parallel with the ridge of the prism element 21 including the center of a screen, also becomes the divergent beam of light. Since the Fresnel lens 22 has a positive refracting power, when the divergent beam of light is made incident on the Fresnel lens 22, the divergent angle of the refracting beam of light of the lens is reduced, then it becomes nearly a parallel beam of light, and on an average, the beam of light advancing the inside of the second translucent plate 20 becomes the beam of light almost in parallel with a center axis.

Filed: 1984-10-25
Abstract: PURPOSE:To execute the incorporated input output processing from plural input output requesters to a pair of input devices by installing a selecting device, etc., to remove one out of the detecting devices to receive plural input output requests and the respective requests. CONSTITUTION:The detecting device 100 detects the presence and absence of an input output request from an input terminal 10 and when the input output request is executed, the request is outputted to a selecting device 206. At the device 206, plural inputted input output requests are selected in accordance with an output signal 31 from a change-over device 500 and outputted to an input output control device 400. The device 400 inputs the output signal 50 from an input device 700 and outputs an output signal 41 to a display device 800. In such a case, the device 800, when the input output request, which is not selected even during the display based upon the signal 41, is inputted through an accumulating device 300 as an output signal 21, displays the designating character at the special position. Thus, in accordance with the necessities, the input output requester is changed, and the input output requester from plural input output requesters to a pair of input output devices can be processed in unification.

Title: Switchboard and container
Inventor: FUKUI MITSURU
IPC: H02B1/28
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent the deterioration of the elastic performance of a packing by being interposed between a door and the draining part of a switchboard body, and to maintain the performance of the packing for the period of the service life of the switchboard by causing a contact-side layer having protrusions on the surface, an air layer, and a fitting-side layer to make a packing to be interposed between the door and the draining part. SOLUTION: The construction for dust proofing, etc., between the door 9 and the body 6 of a switchboard 6 is composed of a door 9, a draining part 8, and a packing 10. And the packing 10 has a three-layer construction composed of a contact-side layer 12 having a plurality of protrusions 11 on a surface being on a side touching the draining part 8, an air layer 13, and a fitting-side layer 14. Since the thickness of the packing 10 is larger than the gap between the door 9 and the draining part 8 when the door 9 is closed, the packing 10 is pressed up to the width of the gap between the door 9 and the draining part 8. But, since only the air layer 13 is crushed, and no pressure is applied to the contact-side layer 12 and the fitting-side layer 14 of the packing 10, it becomes possible to stop up the gap between the door 9 and the draining part 8 wholly.

Abstract: PURPOSE:To provide a noise extracting circuit which can extract the noises out of the video signals with high accuracy and also to provide a noise eliminating circuit which uses the noise extracting circuit. CONSTITUTION:A noise extracting circuit consists of a block forming circuit 16 which subdivides the video signals into (m-row X n-column) blocks, a DCT(discrete cosine transformation) circuit 18 which applied the DCT to the subdivided video signals in a frequency area, a non-linear circuit 20 which selectively selects the noises separated in a frequency space that undergone the DCT, an IDCT circuit 22 which performs the transformation inverse to the DCT and returns the noises in the frequency area to a real space, and a block decomposing circuit 24 which performs the processing opposite to the processing carried out by the circuit 16. A subtractor circuit 14 of a noise eliminating circuit calculates a frame difference between the video signal of the present frame and the video signal of the precedent frame stored in a frame memory 12. Then the noise extracting circuit extracts the noise included in the frame difference signal. This extracted noise is subtracted from the original video signal by a subtractor circuit 10. Thus the video signal free from the noise is stored in the memory 12 and then outputted to the outside.

IPC: G06F21/14
Filed: 1983-11-28
Abstract: PURPOSE:To prevent data from being copied by processing specifically to the cyclic redundancy check (CRC) data contained in data. CONSTITUTION:At the same time when a CRC write timing signals is outputted from a floppy disk control circuit 2, the circuit 2 outputs CRC data, which is supplied to one input terminal of an adder 10 through an AND circuit 8. Said CRC write timing signal is outputted to a shift register 6 at the same time. Consequently, a previously registered cryptographic code is read out of a shift register 6 and supplied to the other input terminal of an adder 10. Therefore, the adder 10 inputs the CRC data and cryptographic code at the same timing and outputs the CRC data with the cryptographic code. This CRC data with the cryptographic code is sent out to a floppy disk device 1 through an AND circuit 22 and an OR circuit 26 and written at the tail of a data field on a floppy disk.
