IPC: H04N9/07
Filed: 1981-01-12
Abstract: PURPOSE:To reduce or eliminate false signals effectively without spoiling the fidelity of color reproduction, color resolution, etc., by permitting an electric circuit to detect and correct the generation of a false chrominance signal when the frequency component of a signal based upon the luminance difference of an object is within a chrominance-signal carrier band. CONSTITUTION:The output of an image pickup tube 1 which has an incorporated stripe filter is amplified by a preamplifier 2, and an LPF3 extracts a luminance signal Y from its amplification output. Further, a BPF6 for control-signal extraction extracts a high-frequency band signal close to the extraction band of the LPF3, and the output terminal of the BPF6 is connected to an arithmetic circuit 7 which generates a value proportional to a smoothed signal by detecting the extraction output. A BPF4, on the other hand, extracts a signal with a band next to the frequency band that the BPF6 extracts, and its extracted signal is inputted to a chrominance signal detecting circuit 5. The arithmetic circuit 7 is controlled by a signal from the circuit 5 to reduce or eliminate false signals effectively without spoiling the fidelity of color reproduction, color resolution, etc.

Filed: 1991-01-11
Abstract: PURPOSE:To realize a smaller circuit scale by designating a circuit element desired to be left and erasing the circuit element judged that any signal carrying route does not exist as to all the circuit elements inside a logic circuit. CONSTITUTION:Circuit data is read and the set S of the circuit element whose output is connected with the external output terminal of the logic circuit within the circuit elements inside the logic circuit is obtained in a device which realizes the logic design of the logic device such as LSI, in a computer as a supporting application program. All the circuit elements outputting to the input of the circuit element added in the aggregation S are added to the aggregation S and the processing is repeated till the circuit element to be added is out. The set S finally becomes the set of the circuit element being logically necessary in the logic circuit. Therefore, all the circuit elements which are not added to the set S are erased from the logic circuit and circuit data is outputted. Thus, the smaller circuit scale is realized by correctly judging the necessity or unnecessity of the circuit element.

Title: Transmission control system
Inventor: NAKATSUGAWA MASAZUMI
IPC: H04B7/24
Filed: 1983-01-12
Abstract: PURPOSE:To minimize the information uncollectable time of a system and to facilitate the search for a faulty station by stopping the system when transmission is performed more than the specific number of times within a specific time and resetting it with a transmission stop reset signal from a master station. CONSTITUTION:When the start signal of a transmission starting circuit 3 is counted by a counting circuit 5 more than specific times, an output switch is opened to stop transmissmion forcibly, and this state is held until the transmission inhibition reset signal from the master station is sent. Even if an answer to any slave station call is made owing to the fault of a recognizing circuit 2, the frequency of the transmission never exceeds the specific value, so the evil influence upon the whole system is minimized and confusion is prevented. Further, when there is a faulty slave station, the transmission is stopped as mentioned above and there is no answer when the slave station is called; and normal cyclic calling is restarted by the transmission inhibition reset signal from the master station, but a communication state is abnormal and when the transmission is stopped, the communication state becomes normal. Thus, when the fautly station is called, no answer is made, so the faulty station is discriminated to facilitate search for trouble.

Title: Measuring method for thickness by radiation
Inventor: INOUE SHIZUO
IPC: G01B15/02
Filed: 1987-01-08
Abstract: PURPOSE:To remove the effect of a change with time and thereby to enable the implementation of measurement of excellent accuracy, by finding a difference between background values obtained when a characteristic curve is prepared and when a thickness is measured, and by correcting a measured value therewith. CONSTITUTION:Back-scattering gamma-rays are measured by a scintillator 1 disposed in close vicinity to a plurality of test pieces 5 being different in thickness. Then a characteristic curve wherein a peak value of a scatter spectrum or the total number of counts thereof within a certain range has a proportional relationship with the plate thickness of the piece 5 is obtained. Moreover, a measured value of the number of counts determined with the piece 5 removed when the characteristic curve is prepared is a background value A. When the wall thickness of a tube 6 in the ground, which is an object of measurement, is measured, the scintillator 1 is conveyed into the tube 6, and the number B of counts corresponding to the wall thickness of the tube 6 is obtained at a position equivalent to the position at the time of measurement of the piece 5. On the occasion, a background value A' is measured outside the tube 6 just before the conveyance into the tube 6. Based on this value, a correction valve C is determined by an equation C=B-(A-A'), and with the value C used as a count value, a measured value of the wall thickness of the tube 6 is obtained from the characteristic curve.

Title: Paper feed device of image forming device
Inventor: ARAI KIYOTAKA
IPC: G03G15/00
Filed: 1994-01-14
Abstract: PURPOSE:To minify a space in the longitudinal direction by separating a feed mean from the sheet in a paper feed cassette, when the paper feed cassette is drawn out from the set position. CONSTITUTION:A paper feed cassette is set on the set position in an image forming device main body, a forward feed roller 50 is brought into contact with a sheet received in the paper feed cassette in this condition, and the sheet is fed in the paper feed direction. Meanwhile when the paper feed cassette is drawn out from the set position, the forward feed roller 50 is diverted from the sheet of the paper feed cassette by a diverting mechanism 53. When the paper feed cassette is drawn out in this way, the forward feed roller 50 is separated from the sheet, and hence it is unnecessary to bring the paper feed cassette down like a customary device for example. Consequently the space of the image forming device in the vertical direction can be minified. In addition, when the paper feed cassette is drawn out, the forward feed roller is separated from the sheet by interlocking with that movement of drawing out.

Title: Runaway detecting system for microcomputer

IPC: G06F11/00
Filed: 1991-01-16
Abstract: PURPOSE:To easily detect the runaway of a program by discriminating whether or not the program has passed all check points when a runaway detecting timer is cleared by means of the program. CONSTITUTION:A microcomputer 102 reads out a program from a memory 101 and, upon receiving a passing state indicating register setting instruction, writes '1' in a passing state indicating register 104-1. Then, at the time of executing a watch dog timer clear instruction, the microcomputer 102 outputs a timer clear request signal 102-1 to a watch dog timer control section 104. The section 104 clears a watch dog timer 103 and, at the same time, resets the register 104-1 to '0'. In case the passing state indicating register setting instruction is not executed, the register 104-1 is left reset to '0'. When such state occurs, the control section 104 discriminates that the program runs away and outputs a runaway detect signal 104-3 to the microcomputer 102.
