Title: Magnetic recording and reproducing device
Inventor: SHIBATA AKIRA
IPC: G11B20/00
Filed: 1982-11-01
Abstract: PURPOSE:To improve the complexity of a recording and reproducing circuit compressing a sound signal in accordance with time and recording the compressed sound signal in an overlapping part by switching signals to be written in a video track and the overlapping part by an output from a recording current setting circuit and a pilot signal. CONSTITUTION:A sound FM processor 3 converts a sound signal into a sound FM signal AFM. An adjuster 64 sets up the recording current of a sound FM signal, a low frequency chrominance signal and a pilot signal collectively. Terminals 52, 53, 54 show the input terminals of the sound FM signal, the low frequency chrominance signal and the pilot signal respectively. The circuit constitution is simplified by adjusting the sound FM signal, the low frequency signal and the pilot signal, keeping the pilot signal on an overlapping track in which a recording level is not severe without adjustment, connecting the level adjuster for said three kinds of signals to the input side of switches 74, 81 and the output side of a mixing circuit, and connecting recording current setters 57, 58 for the sound signal and a luminance signal to the input side of the switches 74, 81.

Abstract: PURPOSE:To obviate the generation of painting defects such as color blobs and thinner splashes during painting work by executing cleaning while ejecting air from air ejection holes of an air ejector at the time of color changing and cleaning after the painting work. CONSTITUTION:The air ejector 20 which is larger in diameter than a bell cup 5 of a mini-bell type coater and has the plural air ejection holes 21 on the bell cup side surface is mounted to the rear part of the bell cup 5 and an air source is connected to said air ejector 20. More specifically, the cleaning is executed while the air is ejected from the air ejection holes of the air ejector at the time of color changing and cleaning after the painting work, by which the cleaning thinner and cleaning air are guided in the fixed direction without being splashed to the outside. The generation of the painting defects such as color blobs and thinner splashes during the painting work is, therefore, obviated.

Title: Exhaust emission control device for internal combustion engine
Inventor: SUZUKI NAOTO
IPC: F01N3/08
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To hold the frequency of S poisoned recovering operation of a NOx storage reduction catalyst without deteriorating fuel consumption. SOLUTION: A NOx storage reduction catalyst 7 is arranged in an exhaust passage 2 in an internal combustion engine, for absorbing NOx in exhaust gas when an exhaust air-fuel ratio is in a lean condition, and for discharging and reduction-purifying NOx absorbed when the exhaust air-fuel ratio is in a rich condition. A recovering operation is carried out only in a specified operating condition of an engine for discharging SOx absorbed together with NOx in the NOx storage reduction catalyst by heating the NOx storage reduction catalyst. In preventing deterioration of fuel consumption in the engine, the more the SOx holding rate of the NOx storage reduction catalyst is increased, the more an engine operating condition is increased for carrying out the recovering operation.  Accordingly, the more the SOx holding rate increases the easier the recovering operation is carried out therefore it is possible to prevent a condition in which the SOx holding rate of the NOx storage reduction catalyst is increased from continuing for a long time.

Title: Multiplex light measuring apparatus
Inventor: FUKUHARA TORU
IPC: G01J1/44
Filed: 1986-08-19
Abstract: PURPOSE:To obtain an adequate exposure data, which is not affected by high and low luminances, by blocking outputs exceeding a threshold value among measured light outputs, which are obtained by dividing an object field into a plurality of regions and measuring light, to an output circuit, and transmitting the outputs, when the blocked measured light outputs exceed a specified number, to the output circuit. CONSTITUTION:A blocking circuit 101 controls analog switches 103, 105 and 107 based on a threshold level, which is set by the presence of the sun on an image plane during the day or at the sunset. Thus, transmission of the photoelectric outputs to circuits 11-13 is blocked. A blocking circuit 103 compares the output with the threshold level corresponding to a lower measured light limit. When the photoelectric output lower than the threshold value is present, analog switches 104, 106 and 108 are controlled, and the transmission of the photoelectric output to the circuits 11-13 is blocked. A flag l, which indicates whether the number of blockings is higher or lower than a specified value, is generated and applied to a classifying circuit 20. The circuit 20 receives a flag (n) and the flag l and classifies the inputs into five categorires. Based on the output of the circuit 20, an apex operating circuit 24 generates an output corresponding to an adequate exposure value and applies the value to an exposure control circuit 25 and an exposure display circuit 26.
