摘要:
A tone signal detector for use in paging receivers, transceivers, mobile radio equipment and the like is disclosed. Received tone signals are waveform-converted to generate complementary gating pulses. These gating pulses are used to gate clock pulses to one of two counters, each of which produce a detecting pulse upon counting up to a predetermined number during a predetermined time interval. A detecting pulse from one counter resets the other, and a detecting pulse from either enables a third counter to count clock pulses. This third counter will produce a detecting pulse upon counting up to a predetermined number during a predetermined time interval. The first and second counters enable the tone signal detector to yield detecting pulses without being adversely affected by threshold variations in the waveform converting circuit, while the third counter examines frequency deviation of incoming tone signals.

A straight-flow exhaust purification catalyst (13) and a hydrocarbon supply valve (15) are arranged in the engine exhaust passage of an internal combustion engine. A region which is a limited portion of the upstream-side end-surface peripheral part of the exhaust gas purification catalyst (13), where there is a possibility of clogging due to deposition of fine particles in the exhaust gas, is predicted to be a fine particle deposition region, and an air-fuel ratio sensor (23) is arranged within an exhaust gas circulation region, which is downstream from the downstream-side end-surface peripheral part of the exhaust purification catalyst (13) and is downstream from the fine particle deposition region when viewed along the longitudinal axis of the exhaust purification catalyst. When the air-fuel ratio of the exhaust gas flowing into the exhaust purification catalyst (13) momentarily changes and the rate of change of the output value from, the air-fuel ratio sensor (23) decreases, it is determined that clogging due to deposition of fine particles in the exhaust gas has occurred in the fine particle deposition region in the upstream-side end-surface peripheral part of the exhaust purification catalyst (13).

摘要:
First, a binary image is generated by binarizing an image. Next, a binary pixel ratio, that is a ratio of a binary pixel quantity that is a quantity of dotted pixels included in a specific area of the binary image to a total quantity of pixels included in the specific area of the binary image, is found. Then, a thin-line image is generated by performing a line-thinning process on the specific area. After that, a thin-line pixel ratio that is a ratio of the quantity of dotted pixels included in the generated thin-line image to the binary pixel quantity is found, and the specific area is determined to be a map area or a photograph area based on the calculated binary pixel ratio and the calculated thin-line pixel ratio.
