    摘要： A semiconductor infrared emitting device is fabricated from an n-type gallium arsenide substrate, an n-type gallium arsenide layer on the top surface of the substrate, a p-type gallium arsenide layer formed on the n-type gallium arsenide layer for forming a p-n junction therebetween, and electrodes provided on the p-type gallium arsenide layer and the reverse surface of the substrate for applying a bias voltage to the p-n junction, and the side surface of the substrate declines from the cleavage surface of the gallium arsenide substrate so that the incident angle of infrared varies at the crystal surfaces, thereby allowing the infrared to be radiated from the semiconductor infrared emitting device.

    摘要： A velocity error compensator is provided for use in a time base corrector of the type having a memory into which successive samples of a periodic information signal, such as a video signal, are written at a write-in rate that is synchronized with time base errors in the information signal, such that plural periods, such as plural lines, of the information signal are stored in the memory, and from which the successive samples are read at a constant read-out rate. The velocity error compensator comprises a velocity error detector for detecting velocity errors in successive periods, or lines, of the information signal written into the memory; and a sample level compensator for compensating the level of a sample read out from the memory as a function of the detected velocity error, such that the level of the read out sample is modified to be equal to the level that the read out sample should have had at the time it was read out if there had been no velocity error.

    摘要： A multi-channel recording and/or reproducing apparatus is disclosed, wherein a plurality of rotary magnetic heads scan a magnetic tape to form a plurality of skewed parallel tracks simultaneously. These heads are aligned substantially in the scanning direction on a single head base plate. Preferably, these heads are so secured as to form parallel skewed tracks without guardbands therebetween. Each head has the same thickness, and is mounted on a head base. Even though the thickness of each head chip is the same, effective head gaps are formed to have different heights individually from the surface of the head base plate. When forming guardband-less plural tracks, an azimuth recording technique is introduced in order to avoid crosstalk between adjacent channels during reproduction.
