Title: Automatic focusing camera
Inventor: NOZAWA SHIYOUZOU
IPC: G03B3/00
Filed: 1979-02-20
Abstract: PURPOSE: To perform the photographing of accurate focusing with a simple constitution by restraining the photographing-lens-moving helicoid by the lock member which interlocks to an electromagnetic magnet for releasing shutter release-system lock by focusing signal.  
     CONSTITUTION: When an electromagnetic magnet 20 is de-energized by the focusing signal, a release second stage lock member 10 is turned by the elastic force of a spring 21, and the second stage lock of a shutter button 12 is released. The pin 24 of a photographing lens 11 is pressed by turning of this member 10, by which a restraining member 28 is tilted with a support portion 28a as a fulcrum and its inside peripheral edge part abuts against the cylindrical part 27 of a helicoid 26, causing the helicoid 26 for moving the lens 11 to be locked at the focusing. Hence, if the automatic focusing camera of this simple constitution is used, the out-of- focus does not occur and the photographing of the matched focus may be surely accomplished.

IPC: G01R23/02
Filed: 1984-02-03
Abstract: PURPOSE:To detect frequencies up to about 1/10 as high as the sampling frequency of an input signal from a direct current with high accuracy by changing detecting means according to the sampling frequency and frequency range of the input signal. CONSTITUTION:The voltage of a system 1 is stepped down to a signal level by a potential transformer 2 to obtain the input signal. Then, the input signal inputted to an analog input card 3 is sampled at a specific sampling frequency and also A/D-converted before being inputted to a microprocessor 4. Then, sampling data are processed by a microprocessor 4 to obtain the frequency of the input signal, which is displayed numerically on a display device 6 through a digital output card 5. Thus, frequencies up to about 1/10 as high as the sampling frequency are detected with high accuracy from the direct current at a relatively low frequency, e.g. a sampling frequency of order about 10 times as high as a frequency to be detected.

IPC: G10K15/00
Filed: 1995-01-09
Abstract: PURPOSE: To attain natural senses of sound image positioning, distance and expansion in all directions by the use of a headphone or an innerphone. CONSTITUTION: A sound signal from a signal input means 1 is applied to an A/D converter 2, which converts the sound signal into a digital signal at a sampling frequency fs. At the time of inputting the digital signal, a signal processing means 3 executes operation for sound image positioning by the use of an FIR filter. In this case, a convolution coefficient is over-sampled and a tap position for multiplying the convolution coefficient is finely controlled in accordance with a distance difference between both ears of a listener. Thus the convolution coefficient is controlled in accordance with the shape and size of the head part of the listener and positional relation between the listener and a sound image. Thus the operated sound signal is applied to D/A converters 4a, 4b and D/A converted signals are outputted from speakers 6a, 6b of a headphone through amplifiers 5a, 5b.
