摘要:
A methacrylic resin having reduced water absorption properties, useful in optical instruments and as information recording substrates, is produced by polymerizing a mixture consisting of (A) 50 to 85% by weight of a methyl methacrylate, (B) 15 to 50 by weight of a cyclohexyl methacrylate and (C) 0 to 30% by weight of the other copolymerizable with said monomer (A) and (B), or partially polymerized product thereof.

A novel methacrylic resin shaped article is made of novel compositions comprising (A) 80 to 99.9% by weight of methyl methacrylate polymer or copolymer, which forms continuous phase, and (B) 0.1 to 20% by weight of a polymer obtained from at least one unsaturated monomer of the general formula ##STR1## wherein R.sub.1 is H or methyl group and R.sub.2 is a hydrocarbon radical of at least two carbon atoms, a derivative or monomer mixture thereof, the respective refractive indexes (n.sub.A) and (n.sub.B) of said (A) and (B) polymers satisfying the relation of 0.998.ltoreq.n.sub.B /n.sub.A .ltoreq.1.002. The above shaped article has a latent mat surface, which therefore may be converted to a mat surface merely by means of stretching at a temperature above heat distortion temperature.

An endoscope apparatus comprises: a scope comprising a solid imaging device; a processor unit which forms an observation image from signals emitted from the solid imaging device, the processor being connected to the scope; and a plurality of monitors each of which is connected to the processor unit, wherein a whole image of the observation image is displayed on at least one of said plurality of monitors, and a partial image of the observation image is enlarged and displayed on the other one(s) of said plurality of monitors.
摘要:
The sharpness of an image obtained by an endoscope is adjusted. A sharpness enhancement amount is determined for each pixel based on the value of each pixel which forms a luminance distribution image. Further, a portion contributing to adjustment of brightness and a portion contributing to adjustment of saturation in the sharpness enhancement amount are determined for each pixel of the image so that the sum thereof is equal to the sharpness enhancement amount. Then, an adjustment value of saturation, which is obtained by weighting the value of each pixel of the image based on the portion contributing to saturation, and an adjustment value of brightness, which is obtained by weighting the value of each pixel of the luminance distribution image, which corresponds to each pixel of the image, based on the portion contributing to brightness, are added to the value of each pixel of the image.

摘要:
In a diagnostic system, a diagnostic unit for an operator of an electronic endoscope and a diagnostic unit for an instructor are in half-duplex radio communication. An inquiry that is input as a voice signal through a microphone into the electronic endoscope is superimposed on a modulated picture signal while shifting the phase of the voice signal, to produce an RF signal, which is sent as an electric wave to an operator's processor and an instructor's processor. The processors demodulate the RF signal, to display an endoscopic image based on the picture signal and output the inquiry through speakers based on the voice signal. An instruction that is input as a voice signal through a microphone into the instructor's processor is superimposed on a dummy signal, to produce an RF signal, which is sent as an electric wave to the operator's processor, to output the instruction through the speaker.
摘要:
An electronic endoscope system has a personal computer, an adjustment monitor and an adjustment processor unit. The personal computer is for changing parameters related to image quality of an endoscopic image. The adjustment monitor displays an adjustment screen, showing information of the parameters, synthesized on an endoscopic image. The adjustment processor unit is connected to the personal computer and the adjustment monitor. The adjustment processor unit produces adjustment data in a data producing section in accordance with changes of the parameters input from the personal computer and sends the adjustment data from a transmitter to an electronic endoscope. The adjustment processor also receives an imaging signal from the electronic endoscope by a receiver and produces the endoscopic image from the imaging signal in a signal processing section. The adjustment processor then synthesizes the adjustment screen onto the endoscopic image and outputs the synthesized image to the adjustment monitor.
摘要:
Connection pads and alignment marks are formed on a long metal thin plate that is carried in a longitudinal direction, and then an insulating layer for covering the connection pads is formed. Then, via holes, which are aligned and arranged on the connection pads by utilizing the alignment marks, are formed in portions of the insulating layer. Then, n-layered (n is an integer of 1 or more) wiring layers connected to the connection pads via the via holes are formed, and the connection pads and the insulating layer are exposed by removing the metal thin plate.

A wiring layer forming wirings containing inner leads and outer leads are formed on a flexible substrate. Then, inner lead reinforcing electrodes to which a semiconductor chip is connected are formed on the inner leads, outer lead reinforcing electrodes are formed on the outer leads, and wiring reinforcing portions are formed between the inner leads and the outer leads on the wiring layers. The flexible substrate is mounted onto an electronic device by folding a portion to which the wiring reinforcing portions are provided between the inner leads and the outer leads.
