Title: Converter from optical image information to electrical signal
Inventor: HAYASHI YUTAKA
IPC: H04N5/335
Filed: 1989-04-03
Abstract: PURPOSE:To enable an image signal to agree with an optical image by synchronizing and scanning a sweep light and a sweep light for synchronization each other, and by allowing a series of pulse signal for synchronization to be output from a photoelectric conversion structure part by a sweep light for synchronization for one main scanning of sweep light, and by performing the above processing for each move of each picture position. CONSTITUTION:A grating 70 consists of a light-transmission part which agrees with the image cycle of an optical image and a light shut-off part which is placed repeatedly in a specified cycle in a direction crossing the paper surface at right angle. A sweep light Id is provided with a light flux section in a shape to be extended in the direction which is parallel to the paper surface and also is used as a sweep light for synchronization. A signal light Is from the side of a transparent electrode 23 supports a one-dimensional optical image signal. When scanning is made from the side of a transparent substrate 10 by the sweep light Id, the part becoming a sweep light for synchronization on the right side of the light Id passes through a light-transmission part and incides a photoelectric conversion layer for receiving sweep light for synchronization, and the scanning effect is cycled. Thus, pulses corresponding to the picture element position of optical image information are generated between terminals T1 and T3.

Filed: 1994-04-22
Abstract: PURPOSE:To reduce interference quantity by making the transmission power of a synchronizing signal lower than that of a spread modulation signal to transmit the synchronizing signal from a terminal station at the time of setting a communication line. CONSTITUTION:A synchronizing signal generator 2a of a terminal station 2 generates a synchronizing code peculiar to the station 2 itself to give it to a gain control part 28 at the time of setting the communication line. The gain control part 2e adjusts the gain of the transmission power of the synchronizing code to give it to an adder 2f, and the synchronizing code is sent to a transmission line through the adder 2f. Modulation signals from other terminal stations are added on the transmission line 3, and they are given to a demodulator 1a of a base station 1. When synchronism is settled, a control part 1c makes a spread modulator 1b spread and modulate a synchronism completion signal, and it is outputted to the transmission line 3. A demodulator 2d of the terminal station 2 demodulates the signal from the base station 1 with a preliminarily determined spreading code. If reception data is a synchronism settlement message, a control part 2c controls a gain control part 2e and reduces the transmission power of the synchronizing signal to transmit the signal.

Filed: 1992-04-07
Abstract: PURPOSE:To prevent an image from being distorted owing to a liquid prism by reducing the vertical temperature unevenness of the liquid in the liquid prism and making the refractive index distribution uniform. CONSTITUTION:The prism container 11 of the liquid prism 10 filled with the liquid 7 is separated into a polarizing plate chamber 15 and a polarizing mirror chamber 16 with a partition 14. When luminous flux with Gaussian distribution intensity is made incident from a light source 1, the liquid 7 made warm at the center part of the prism by the light absorption of a polarizing plate 8, etc., rises by the convection to generate temperature unevenness in a vertical direction. The partition 14, however, parts the thermal influence between the polarizing plate chamber 15 and polarizing mirror chamber 16, so the temperature unevenness is generated while limited to the polarizing plate chamber 15 where heat absorption is large and the temperature unevenness in the polarizing mirror chamber 16 is small.

Abstract: PURPOSE:To improve resistance to a code error and to apply a system even to variable length frame constitution by combining plural characteristic words with characteristic words or noncharacteristic words which are as many as said characteristic words alternately without overlapping, and thus constituting plural control codes. CONSTITUTION:In a figure, P1-P6 are characteristic words, which are never generated in a data sequence of codes other than control codes. Further, P7-P12 are characteristic words or noncharacteristic words which are low in generation frequency in a data sequence. Respective elements are extracted from a group of P1-P6 and a group of P7-P12 alternately without overlapping to constitute the control codes C1, C2, and C3. On a transmission side, a control code is inserted into each frame, which is sent to a reception side. When the data sequence is received on the reception side, on the other hand, it is decided whether or not a combination of >=2 words containing >=1 characteristic code in four successive words coincides with a combination present in the control code and when so, it is considered that there is the corresponding control code at a corresponding position.
