Title: Fine capacitance variation detecting circuit
Inventor: NOGUCHI KOUICHI
IPC: G01V3/08
Filed: 1982-09-29
Abstract: PURPOSE:To enable a highly accurate detection of changes between fine gaps depending on variation in the low frequency by forming a negative feedback path of an LC oscillator with an electrostatic capacitance of fine gap detection electrode. CONSTITUTION:The collector and the base of a transistor Q1 are connected to detection electrodes 4 and 5 forming an electrostatic capacitance and a high frequency component is passed through the electrostatic capacitance between the collector and base so that the amplification factor of the transistor Q1 decreases. As the electrostatic capacitance increases, namely, the fine gap l becomes smaller, the amplification factor lowers to reduce the frequency. Thus, changes in the fine gap l can be read from variation in the frequency. When arranged in the conveying path of a transfer paper, this circuit enables the detection of feeding condition of the transfer paper.

Title: Device for compensating aborted packet in voice packet communication
Inventor: HORIGUCHI KENJI
IPC: H04L12/70
Filed: 1988-07-11
Abstract: PURPOSE:To minimize the deterioration in the quality of voice due to packet missing by including a high pass filter eliminating a low frequency component of a voice signal given from a control means to an output means. CONSTITUTION:A voice signal extracted from a packet 10 received by a reception means 14 normally is outputted to an output means. When missing of a packet is detected by the reception means 14, a final value of a period just before a missing packet stored in a storage means 26 is outputted to the output means. The output of the final value is continued at least the period of the missing packet elapses and the voice signal extracted by the reception means at the next period crosses the final value. Thus, the signal is subject to the 0th order holding over a period longer than the voice period of the missing packet and a low frequency component of the voice signal subject to the 0th order holding is eliminated by a high pass filter means 70. Thus, the DC or low frequency component caused in the reproducing signal is eliminated and the voice signal with minimized discontinuity is reproduced.

Title: Method and circuit for dynamic adaptive frequency overlapping
Inventor: KIN YOUTEI
IPC: H04N9/797
Filed: 1992-06-29
Abstract: PURPOSE: To prevent the degradation of the picture quality due to an artifact at reproduction by superposing a signal component of a certain frequency or higher on that of a frequency lower than the certain frequency based on the quantity of a motion signal and recording the overall band on a recording medium in a limited band. CONSTITUTION: A horizontal LPF 10 receives a luminance signal Y and allows only a signal component of a prescribed cut-off frequency or lower to pass through, and a horizontal HPF 20 allows only a signal component higher than this frequency to pass through. A motion signal detection part 30 generates a factor value K corresponding to a motion signal after detecting the motion signal from the luminance signal Y. A signal adjustment part 50 outputs a high frequency luminance component which has the gain adjusted by an adaptive emphasis/ deemphasis part 40 only when the magnitude of K is in a prescribed level for discrimination of a still picture or lower. Consequently, an addition part 60 adds and outputs the high band component passing the adjustment part 50 and the low band component passing the LPF 10 in the case of a still picture and outputs only the output of the LPF 10 in the case of a moving picture and adds and outputs low and high band components based on the current K value in the case of a quasi-moving picture. Thus, the picture quality is improved.

Abstract: PURPOSE:To make the display of a stereoscopic screen possible and to maintain the dot density constant by forming a grooved fluorescent screen having 2 surfaces which are directed to 2 different directions each other, and independently scanning these two surfaces. CONSTITUTION:A fluorescent screen 10 which can be mainly seen by a right eye and a fluorescent screen 11 which can be mainly seen by a left eye are located opposite to each other to form a plurality of grooves which are parallel. Scanning lines 8 are generated in the screen 10 by means of an electron gun 5 for a picture of the right eye, and scanning lines 7 are generated in the screen 11 by means of an electron gun 6 for a picture of the left eye. If these 2 picture are different, it is possible for the eyes of a man to see a stereoscopic picture on the basis of these difference. Further, since the screens 10, 11 are directed to the directions of the electron guns 5, 6 respectively, it is possible to make the scanning angle 9 of each scanning line small in comparison with the conventional scanning angle due to 1 electron gun, and thus it is possible to maintain the dot density constant.
