Title: Detecting system for signal interruption
Inventor: IKEUCHI SATOSHI
IPC: H04L25/02
Filed: 1981-05-23
Abstract: PURPOSE:To surely discriminate the interruption of input, by dividing an output of a self-pickup timing circuit into two, and applying one directly and another with delayed phase to a flip-flop, in a relay device providing a self-pickup timing  circuit. CONSTITUTION:When a data signal is inputted, a self-pickup timing circuit 1 picks up, reproduces and outputs a clock signal (a). The signal (a) is divided into two; one is directly applied to an input D of a flip-flop 2 and another is given to a delay circuit 3 and a delayed signal (b) is applied to an input C of the flip- flop 2. An output (c) of the flip-flop 2 is applied to a DC/AC signal discriminating circuit 4 to detect the level of AC component. Thus, when an input signal is presented, the relation of phase of the signals (a) and (b) is always constant, and a signal (d) represents a low level indicating the presence of the input. If the input signal is interrupted, the relation of phase of both the signals (a) and (b) cannot be kept constant, an AC component is produced in the detection signal (c) and the detection signal (d) goes to a high level, which indicates the interruption of signal.

Title: Image recorder
Inventor: INOUE TAKAHIRO
IPC: B41J2/44
Filed: 1986-04-07
Abstract: PURPOSE:To improve quality of a recorded image in an electrophotographic image recorder using a fine beam Iight source such as laser beams by controlling the exposure time per picture element in response to the distribution of the sensitive characteristic deviation of a photosensitive body. CONSTITUTION:An optical slit 4 is disposed before a lens 5, and the cosine four-production of the lens 5 and the sensitive characteristic deviation in the bus line direction of the photoshnsitive body (drum) 14 are simultaneously corrected. Since the more sensitive part of the photosensitive body 14 requires a low exposure quantity, the width of the slit 4 is narrowed to control Iight so that less light can be irradiated to a CCD 5. Whereas the less sensitive part of the photosensitive body 14 requires a greater exposure quantlty than the prescribed one, the width of the slit 4 is expanded to control light so that more light can be irradiated to the CCD 5. Thus the CCD 5 can obtain an picture signal corrected by the deviation of the sensitive characteristic distribution of the photo sensitive body 14.

A stage 6 is moved in X- and Y-directions with each segment by a control circuit 5 and an electronic shutter 14 is opened and 23 is closed by a change over switch 26 to set a focusing mode. The sample S is then illuminated from the rear. The video signal is taken by a television camera 3 into a focus detecting circuit 4 by which said signal is subjected to the computation to evaluate the degree of focusing. The stage 6 is then moved upward and downward by a pulse motor 8 and the signals are similarly subjected to the evaluation of the degree of focusing and are compared with the previous value. The illumination is changed over to reflection illumination after decision of focusing and the video signal is taken in by the camera 3. The circuit 5 makes decision of whether the video is defective or non-defective according to the presence or absence of the signal above the prescribed level and memorizes the result thereof. This operation is executed over the entire surface and the degree of focusing is evaluated by the positions and number of the defective sections. The focus detection of the plain and smooth sample is thus carried out.
