IPC: H04N5/232
Filed: 1993-03-26
Abstract: PURPOSE:To make a device compact by reducing a storage capacity. CONSTITUTION:This device is equipped with an image pickup camera part which divides a screen into V lines and H columns, and outputs a video signal in one line sweeping time T0, an A/D converting part which operates the sampling of the picture element information of the video signal in a cycle T1, converts it into digital information, and outputs it, a memory part which stores the digital information, and arithmetic processing part which video-recognizes the presence or absence of an object to be detected based on the picture element digital information stored in the memory part. When a roughly divided area beta(i, j) matrix required for video-recognizing the presence or absence of the object to be detected is (v) lines and (h) columns, the A/D converting part sets the sampling cycle T1 as T1=T0X(v/V). When the image pickup camera part outputs the video signal in the Nth line in the V lines divided into (v), the A/D converting part starts the sampling synchronously with the picture element information in one of the {(N-1)X(V/v)+1} to {NX(V/v)}-th columns.

Abstract: PURPOSE:To make the circuit operation stable by frequency-dividing an oscillated output signal in a phase locked loop circuit so as to generate a synchronization detection input signal in the case of demodulating a phase modulation signal by the reverse modulation system. CONSTITUTION:A frequency divider 22 frequency-divides an oscillation output signal in a phase locked loop(PLL) circuit 14 at an even number of division, the frequency division results in generating a frequency division signal caused at a nearly constant period of leading/trailing.

Thus, unstable circuit operation is avoided.

Filed: 1980-05-23
Abstract: PURPOSE:To obtain a more easy-to-see display device, by varying the emitted light volume of a circuit state display device of a key telephone set according to the peripheral brightness. CONSTITUTION:An LED lighting relay of a main device operates to close an LED lighting relay contact 1. Thus the current flows in a route of the positive terminal of a current source 2 - a power supply line 4 - LED6 - the parallel circuit of a resistance 5 and CdS7 - an LED lighting control line 3 - a contact 1 - the earth of the power source 2. Thus the LED6 glows. The CdS7 is attached on the surface of a housing of the telephone set. The resistance value of the CdS7 is reduced when it is bright around the telephone, and thus the value of the current flowing to the LED6 increases to increase the emitted light volume of the LED6. Thus the resistance value of the CdS7 increases when it is not bright around the telephone. Thus the value of the current flowing through the LED6 decreases to reduce the emitted light volume of the LED6.

Thus, the column inlet pressure is kept constant at always, so reproductivity of gas chromatograph analysis is assured. In addition, excessive loss of a sample is prevented, and drop of analysis sensitivity is prevented.

Title: Mark detection method
Inventor: SAMOTO NORIHIKO
IPC: H01L21/30
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the deterioration of precision of mark position detection, by applying positive type resist for electron beam exposure, and thinning the resist thickness of a reference mark part, by light exposure and self development. CONSTITUTION:Self-development is made to generate, by exposing in batch positive type resist 13 for electron beam exposure on a reference mark 11 for electron beam exposure, by using optical exposure or X-ray exposure or electron beam 15. Time required for the process is short, and further the film is thinned by self development. As a result, a mark detection signal can be obtained with excellent precision, even in the case of a small current. Since the mark is not exposed when resist inverting from a positive type to a negative type by exposure with light, the damage of the mark in a post-process can be prevented, and the identical mark can be used again.
