Title: Photographing lens and camera using the same
Inventor: KOIKE KAZUMI
IPC: G03C3/00
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a photographing lens constituted of two lenses being two groups where the illuminace of an image surface is high and the fluctuation of aberration is restrained without lowering moldability. SOLUTION: This photographing lens 30 is constituted of a 1st lens 31 which is meniscus and whose concave surface turns to an image side and a 2nd lens 32 which is meniscus and whose concave surface turns to an object side. Both of the lens surfaces 31a and 31b of the 1st lens 31 are formed to be spherical and at least either of the lens surfaces 32a and 32b of the 2nd lens 32 is formed to be aspherical. When it is assumed that the focal distance of the 1st lens 31 is f1, the focal distance of the 2nd lens 32 is f2, a condition |f1|<|f2| is satisfied. Since the focal distance of the 1st lens 31 is short and the effective diameter thereof is large, it is hard to mold the 1st lens 31 in an excellent plane state but the lens surface is formed to be spherical, so that molding accuracy is moderated and the moldability is improved.  Even when the lens surface of the 2nd lens 32 is formed to be aspherical, desired optical performance is secured even though the molding accuracy is not kept high, because the focal distance of the 2nd lens 32 is long and the effective diameter thereof is small.

Title: Transmission type screen
Inventor: TACHIBANA KAZUHIRO
IPC: G03B21/625
Filed: 1990-01-17
Abstract: PURPOSE:To prevent the lowering of brightness and the occurrence of the unevenness of color on a screen by crossing the extension lines of light emitted to an observation side to a light source side on a plane which passes the light source and is parallel with a screen substrate. CONSTITUTION:The extension lines of the light emitted to the observation side to the light source 1 side are crossed on the plane which passes the light source 1 and is parallel with the screen substrate 20. A prism group 2A like this is easily formed by successively machining a prism element 21 in accordance with a contact angle beta by the use of a both-surface cutting tool corresponding to an edge angle tau. Thus, even when the light of the light source made incident at a steep angle is totally reflected, the emitted state of the reflected light in vertical and horizontal planes is balanced. Then, the lowering of the brightness and the occurrence of the unevenness of color on the screen are prevented.

Title: Light carrier detector
Inventor: SUZUKI TAKAMASA
IPC: H04B10/00
Filed: 1985-01-21
Abstract: PURPOSE:To obtain a stable carrier detection signal by comparing a signal obtained by sample holding carrier of light receiving data and integrating and threshold voltage by a comparator and outputting a carrier detection signal. CONSTITUTION:When maximum voltage of an output signal 26 of a sample holding circuit 5 is VH, minimum voltage is VL, threshold voltage 28 is set between VH and VL. Even in the case where the carrier does not exist on the output signal 24 of the first comparator 4 when pulses are generated on a sample signal 25 by enlarging time constant of the second integrator 6, a carrier detection signal 29 is maintained in the state of H. In such a case, time in which the signal H is kept in the state of H can be set by time constant of the integrator 6 and voltage 28. Consequently, even when light power of data on a light signal 20 varies near the limit of light detection level, and the carrier on the signal 24 is outputted unstably, the signal 29 that discriminates the state of carrier detection is outputted stably.

Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To provide an image processor by which a constant image quality is obtained at contour emphasis processing irrespectively of kinds of image and degree of deterioration. SOLUTION: Regarding a processing object image of the contour emphasis processing, noise information (noise intensity 'α' and noise volume 'β') about a specified density value is preliminarily detected. Based on the noise information, a main correction coefficient reference table is corrected by a main correction coefficient reference table correcting part 82. Then, a contour emphasis signal km(S-U) is generated by referring to the main correction coefficient reference table after correction and simultaneously deciding a main correction coefficient km according to a main signal S by a main correcting part 83. And a corrected contour emphasis signal kekm(S-U) is generated according to a value of the contour emphasis signal km(S-U) by an edge correcting part 84.  After that, a contour emphasized signal E which is the final output signal is generated by adding the corrected contour emphasis signal kekm(S-U) and the main signal S together.

Abstract: PURPOSE:To speed up a binocular stereoscopic vision by making a device include a means to generate a first image without a binocular parallax, a means to generate a left and a right eye images with the variable binocular parallax, and a means to display these images successively. CONSTITUTION:In a figure (a), A0CB0 is an initial presented condition, and a triangle A0CB0 is seen equally as the left eye image and as the right eye image, on a displaying device (C-A0B0 plane in figure (b)).

The data quantity after the compression of the picture caught by each camera is almost the same and the time required for communication is almost constant. The data received by a receiver is expanded according to the parameter added to the data and the original picture data is decoded. Thus, the display is implemented at the receiver side at a prescribed interval and an easy to see picture is obtained.

Abstract: PURPOSE:To have stable feed of sheets regardless of the position of the original sheet's leading edge when the original sheet is set, by furnishing an auxiliary roller, to which the power of feed roller is transmitted, in front of the feed roller. CONSTITUTION:An auxiliary roller 14 rotating in the same direction as the feed roller 11 is furnished in front of the feed roller 11, which feeds original sheets 17 stacked on an original sheets table 18 one after another from above. A bearing is installed on an arm 13 so that the rollers 14, 11 can rotate individually, where the roller 14 shall rotate concentrically to the roller 11. Accordingly the roller 14 is pressed in the direction as Arrow d by its own weight, and thereby makes contact with the uppermost original sheet regardless of the thickness of sheets stacked. That is, the roller 14 rotates in the direction of Arrow c as power being transmitted through a belt 15 to send the sheets stacked in the direction of Arrow b, so that sure contact with the roller 11 is secured even when the leading edge of original sheet is not in contact with the roller 11  when the sheet is set. Thus a smooth feeding of sheets is ensured.
