摘要： The white balance of a television camera is not lost and kept properly even if the diaphragm is opened to the utmost limit at a dark place. A signal F representing the diaphragm value of the taking lens is inputted from an iris part 2 into a microcomputer 8. The level adjusting values of the R, G, and B signals are set in the microcomputer 8 according to the diaphragm signal F and sent to a white balance correcting circuit 6. The correcting circuit 6 adjusts the levels of the R, G, and B signals to the same value according to the level adjusting values.

摘要： An improved blood pressure measuring system based on oscillometric methods utilizes a pressure transducer which provides a varying cuff pressure for occluding the artery of a test subject. The cuff pressure is sampled at a suitable sampling rate to provide a consistent waveform including arterial or blood pressure pulses appearing in sequence during the period of decreasing the occluding pressure. Each blood pressure pulse superimposed upon the cuff pressure is extracted as a pulsating quantity for analyzing the characteristic behavior of such arterial pulse train in order to determine required blood pressure measurements. The pulsating quantity is defined to be an integral of each pulse which value is much larger than the height of the pulse and accordingly, represents an index more readily discernable from possible artifacts having a level in the vicinity of the height level of the pulse.

摘要： A living body information measuring apparatus can suppress the bulge of tendons due to the bending of a wrist or fingers, and has good contact intimacy with arteries, making it possible to make accurate measurements of living body information. A cuff is formed of: a compression fluid bag which is provided for detecting a pulse wave signal, and which can be expanded and contracted by being supplied with a fluid; and two auxiliary fluid bags which are provided on an outer side of the compression fluid bag, and which can be expanded and contracted by being supplied with the fluid. The auxiliary fluid bags have a two-layer structure, and are connected to the compression fluid bag via opening portions, while the auxiliary fluid bags are respectively divided from each other. The compression fluid bag compresses the tendons, the radial artery and the ulnar artery, while the auxiliary fluid bag and the auxiliary fluid bag compress the radial artery and the ulnar artery, respectively. Thus, the bulge of the tendons due to the bending of the wrist and fingers can be suppressed, so that the contact intimacy of the compression fluid bag and the auxiliary fluid bags with the wrist is not hindered.

摘要： By a pressure data separating device 24, a net cuff pressure and an arterial pulse component are separately extracted from a cuff pressure of an occluding cuff which is an electrical signal provided from an A/D converter 23. A waveform value indicative of a waveform of each arterial pulse is computed by an arterial pulse deriving section 24a. An arithmetic operation device 26 is capable of detecting a characteristic value from a time series of the waveform values and determining systolic and diastolic blood pressures of a subject in accordance with a net cuff pressure corresponding to the characteristic value. In the present invention, since particular times associated with the systolic and diastolic blood pressures are derived by an analysis of the waveform of each arterial pulse, the blood pressures can be accurately determined while preventing an error in measurement caused by individual difference of the subject.

摘要： A dark shading correction circuit, used for a television camera or a video camera, is provided for canceling a dark shading signal component contained in a video signal outputted from an image pickup device (6), thereby effecting the dark shading correction on the video signal. In synchronization with a vertical synchronizing signal, the image pickup device (6) outputs a video signal containing an optical black reference signal outputted in response to each horizontal scanning signal, while a timing signal generator (10) generates at least two timing signals for detecting the optical black reference signal in the video signal. On the other hand, detection means (7a, 7b) detect at least two optical black reference signals contained in the video signal based on the at least two timing signals. Correction signal generating means (3, 8, 9) generate and output a correction signal for correcting the video signal in synchronization with the vertical synchronizing signal, based on the detected at least two optical black reference signals, so that the dark shading signal component contained in the video signal is canceled.

摘要： A heating system for a catalytic converter of a multi-cyclinder, spark-ignition engine is provided. Half of the cylinders of the engine, for example, the cylinder #2 and the cylinder #3, are operated on a rich gas mixture with an excess air ratio of 0.6 or less to produce a combustible gas mixture comprising hydrogen, carbon monoxide, and unburned fuel components, while the remaining half of the cylinders, for example, the cylinder #1 and the cylinder #4, are utilized as air blowers to which no fuel is fed. The flammable gas mixture produced from the combustible gas produced in the cylinder #2 and the cylinder #3 and the air supplied by the cylinder #1 and the cylinder #4 is burned in the combustor equipped with an ignition device which is installed upstream from the catalytic converter to provide heat energy to activate the catalyst. The system can rapidly heat and activate the catalyst without requiring a special fuel supply system and air blower.
