Title: Inspecting method for printer quality
Inventor: OKABE TAKASHI
IPC: G06K9/46
Filed: 1985-10-25
Abstract: PURPOSE:To decide easily the quality of printing by outputting a specified pattern from an output equipment and printing it, bringing it to an image pickup by a TV camera, inputting it to an image processor, bringing its contour to polygonal approxima tion, detecting a coordinate of a corner, and bringing the side length to calculation processing. CONSTITUTION:A hard copy form 1 is placed on a transparent inspecting table 4, and by executing illumination from the reverse side part of the inspecting base 4, an area containing enough an output pattern 1a is brought to an image pickup by a TV camera 2 from a normal direction to the hard copy form 1. Its image is binary- coded by an image processor 3, the contour of a pattern of a binary image is brought to polygonal approximation (segment), a train (Xi, Yi, i=1, 2...n) of apex data is derived, and from in the data, four points corresponding to points A-D of the output pattern 1a are selected. Coordinate positions (Ax, Ay) of the point A are derived by selecting the nearest point from in the segmented data, since the origin 0, 0 is the upper left corner of TV screen (broken line). In the same way, coordinates of the point B-D are derived, by which an output width is calculated, compared with a prescribed value, and whether an adjustment of a printing state of a printer is good or not is decided.

Title: Call signal informing system
Inventor: TAKEZAWA MINORU
IPC: H04M1/00
Filed: 1992-09-07
Abstract: PURPOSE:To improve the operability by allowing a called party to detect an additional signal from a caller and set optionally and freely by the caller, converting the signal into a sound string signal corresponding to every signal and outputting the converted signal as a call tone so as to identify the caller with the call tone. CONSTITUTION:An additional signal detection means 1 of each telephone terminal of a transfer enable communication system detects an additional signal set optionally by a caller to a called party together with call request information. A signal conversion means 2 divides the additional signal into individual signal, converts the signal into a tone signal corresponding to every signal and converts to a specific tone string signal. A calling tone output means 3 outputs a call tone based on the tone string signal and a control means 4 controls each section. In this case, an identifier is given to the specific tone signal as a ringer signal with different major scale and individual scale or 50 phonetic sounds are constituted for the signals. Thus, a caller is identified by means of the calling tone, the registration of the call tone is omitted and then the operability is improved.

Title: Agc circuit
Inventor: SHOJI YOSHITERU
IPC: H03G3/30
Filed: 1985-10-23
Abstract: PURPOSE:To eliminate the distortion and the deterioration in the input/output characteristic when a large input signal is supplied to an AGC circuit at the time of a reduced power voltage by using the 2nd variable resistor in addition to the AGC circuit comprising the 1st variable resistor to vary the load of a microphone. CONSTITUTION:An AGC drive amplifier 10 and a variable resistance element 11 are added and the output of the variable resistive element 11 is supplied to a connecting point P between a load resistor 5 and a microphone 9. The signal of a microphone amplifier 1 is led to an amplifier 10, where the signal is compared with a reference level preset in the amplifier 10 and when a signal having the reference level or over is inputted, the output of the amplifier 10 drives the element 11. Since the parallel combined resistance between the element 11 and the load resistor 5 is used as a load of the microphone 9 in this state, although the output of the microphone 9 is reduced, the distortion is reduced also. Since the input signal level to a resistor 4 is lowered, a small drive current is enough to the variable resistance element 3 and even when the maximum output of the amplifier 2 is lowered due to the power reduction, the element 3 can be driven.

Filed: 1984-11-14
Abstract: PURPOSE:To obtain many effective powers at an output by absorbing electromagnetic energy generated at an inductance when a switch element is turned OFF by a capacitor, and supplying it to a load at the special timing. CONSTITUTION:Gate turn OFF thyristors (GTO) 121-126 are used for a rectifier 12, and a freewheel diode 11 and an energy absorber 13 are added. In order to obtain many effective powers at the output by the GTO type rectifier 12, the relation between a firing angle alpha and an extinguishing angle beta is set to the range of an equation (where tau: the electromagnetic energy inverting period of a power source inside inductance, f: a power source frequency). Thus, a pattern voltage Vp and the actual battery voltage VB are compared, and the firing angle alpha of the rectifier 12 is controlled by the deviation VB. At this time the angle is fixed by the constant voltage VB to, for example, beta=30 deg.. Thus, the effective power supplied to the battery 40 can be increased.
