Abstract: A vehicle seatbelt device of an embodiment includes a recognizer that recognizes circumstances around a vehicle, a steering operator that is able to adjust steering of the vehicle, a vibrator that causes a portion of the steering operator to vibrate, a seatbelt that restrains a portion of the body of an occupant of the vehicle, a tension adjustment mechanism that is able to adjust the tension of the seatbelt, and a controller that controls the vibrator and the tension adjustment mechanism on the basis of the circumstances recognized by the recognizer.

Abstract: A receptacle 1 is provided with insertion detecting means 14 for detecting the connection of a device 2, a memory 12 for storing therein a house code, and a power line superposition communication means 11 for superposing the house code on a power line 4. The house code is automatically set in the device 2 when the device 2 is connected to the receptacle 1.

Abstract: When image data of the first line is input, compressor 102 compresses the input image data by every prescribed number of pixels corresponding to the number of pixels included in column direction of one block, and the compressed data is stored in the corresponding region of a memory 104, under the control of control circuit 108. For the second and following lines, the compressed data of the last line which has been compressed and stored in the memory 104 and the input data are received by the compressor 102, and the compressor 102 integrates and compresses the received data, and the compressed result is stored in the corresponding memory region of the memory 104.

Abstract: The present invention aims at providing a novel NOx-decomposing catalyst and a denitrification method using the same. The feature thereof consists in an NOx-decomposing catalyst, in which vanadium oxide is supported on titanium oxide of anatase type, having a specific surface area of 100 to 250 m.sup.2 /g and micro pores of 15 to 25 .ANG. in pore diameter and 75 to 85 .ANG. in pore diameter respectively in an amount of at least 0.05 cc/g, and a method for the denitrification of a waste gas comprising contacting an NOx-containing waste gas with the above described catalyst in the presence of a reducing gas at a temperature of 100.degree. to 350.degree. C. An NOx-containing waste gas with coexistent catalyst-poisonous materials such as water, SOx, etc. can be treated in an effective manner at a relatively low temperature, e.g. 170.degree. C. or lower, at which no practical treatment can be carried out by the prior art method, without formation of N.sub.2 O as a by-product.
