Title: Digital type straight moving-quantity or turning-quantity measuring device
Inventor: UARUTERU SHIYUMITSUTO
IPC: G01D5/244
Filed: 1983-01-26
Abstract: A digital electronic length or angle measuring instrument includes an arrangement for error correction. A signal generator delivers periodic analog reference signals RS1, RS2 which are compared in a comparator with scanning signals S1, S2 generated by the measuring instrument. In accordance with the result of the comparison in the comparator, the reference signals RS1, RS2 are altered as a function of correction data for symmetry, amplitude ratio, phase angle, and signal form, which correction data are determined in a correction component and are supplied to setting members included in the signal generator. In this way, an in dependence on the correction data, improved reference signals are generated which then form a basis for the next comparison in the comparator.

Title: Zinc alkaline battery
Inventor: MIURA AKIRA
IPC: H01M4/42
Filed: 1987-01-20
Abstract: PURPOSE:To increase the corrosion resistance of a zinc alloy used in a negative electrode and to decrease the amalgamation rate of negative zinc by utilizing a synergetic effect produced by the combination of added elements. CONSTITUTION:A zinc alloy containing 0.01-0.5 wt.% at least one of lead, cadmium, and gallium, 0.01-0.2 wt.% aluminum, and 0.01-0.2 wt.% barium and/or strontium is used as active material. Lead, cadmium, or gallium enhances hydrogen overvoltage. Addition of aluminum makes the particle of atomized zinc powder globular and makes the surface of the particle smooth. This increases the corrosion resistance of zinc powder. By adding strontium or barium together with aluminum, corrosion resistance is further increased. Therefore, a zinc alkaline battery whose amalgamation rate is low but practicality is high can be obtained.

Title: Digital gain control circuit for hearing aid
Inventor: SUMIDA TATSUO
IPC: H03G3/02
Filed: 1989-01-19
Abstract: PURPOSE:To attain complicated gain control of an analog signal by converting an analog signal into a digital signal by pulse density modulation, varying the pulse density of the signal in response to the gain data, demodulating it into an analog signal again. CONSTITUTION:A digital control circuit 117 starts decreasing the gain given to a digital variable gain circuit 106 when the pulse density given from a pulse density detection circuit 115 exceeds a control start output and when the pulse density does not reach the control start gain, the circuit 117 starts restoring the decreased gain into the setting gain. If the pulse density exceeds a maximum output by a sudden signal input causing the gain control not to be in time, the digital control circuit 117 outputs a control signal to an output limit circuit 109 to limit the maximum pulse density of the pulse density modulation signal. Thus, even the gain control of a complicated analog signal is easily implemented.

Filed: 1987-01-19
Abstract: PURPOSE:To extract an object image without special operation with high accuracy by identifying a picture element of a background video signal in an input signal based on an inter-frame difference signal of the input signal and making the content of a background memory to be the newest background video signal at all times and extracting the object image while discriminating whether or not a picture element is a picture element in the object image based on the difference signal between said signal and the input signal. CONSTITUTION:An input video signal is delayed for one frame in a background input means 1, the inter-frame difference between said video signal and the input video signal is calculated by a frame difference arithmetic circuit 22 and binarized by a binarizing circuit 23. Based on the binarized difference signal, a background picture element of each frame of the input video signal is identified by the background identification means 2, then the video signal where the picture element part uses the input video signal and the other part uses the video signal read out of the background memory 13 is formed and the result is inputted to the background memory 13 as the background video signal. Since the background image of the input video signal is extracted and stored automatically in this way, it is not required to reinput a background image every time there is a change in the background.

IPC: G11B7/085
Filed: 1985-01-25
Abstract: PURPOSE:To remove a defocusing state speedily by adding a position sensor wich detects the displacement of a focus actuator in a pickup. CONSTITUTION:A focus error signal outputted from the pickup 1 is fed back in normal reproducing mode to the focus actuator through the focus servo looop consisting of a driving circuit 2 and a switch circuit 3 to perform focus servocontrol.

Abstract: PURPOSE:To make the captioned collector indestructible against water pressure or  freezing without increasing the quantity of water therein by a method wherein a water pipe forming part of the collector is made to have such sectional configuration  that the radius of curvature of the internal surface of a connecting section of the water pipe is made larger than the distance between the internal surfaces of th opposing  central upper and lower parts thereof. CONSTITUTION:The water pipe 2 forming part of the collector 1 is made to have such  sectional configuration that the radius of curvature (r) of the water pipe 2 adjacent  to its connecting section 3 is made larger than the distance (t) between the internal  surfaces of the opposing central upper and lower parts thereof. To be more concrete, the water pipe 2 has such a structure that both the central part of the upper surface  and that of the lower surface of the water pipe 2 are indented inwardly or only the  former part is indented inwardly so that the distance between the internal surfaces  of these parts is shortened. Thus, since the captioned collector is formed of the water pipe 2 of the above described structure, the quantity of water passing through the  pipe 2 is not increased and the concentration of stress upon the part around the connecting section 3 due to water pressure or the like is damped so that the pipe is hardly destructed as compared to the known water pipe having its central part expanded outwardly.
