Title: Recording apparatus
Inventor: AOKI TAKAO
IPC: H04N1/40
Filed: 1988-11-15
Abstract: PURPOSE:To well reproduce image quality by preventing granular noise from becoming conspicuous in an image bright part by using a plurality of binarized data generated by a binarizing means to apply a plurality of recording processings to the same input image data. CONSTITUTION:Binarizing processing is twice applied to the image data stored in a buffer 7 but the output gamma-correction table shown by a drawing (a) is used twice alike with respect to image data of C, M while, with respect to image data of Y, K, the output gamma-correction table of the drawing (a) is used the first time and the output gamma-correction table of a drawing (b) is used the second time. The output gamma-correction table (b) outputs an image density signal as '0' even when any signal is inputted. Therefore, in a case performing overlap recording, even when the recording images of Y, K at the second time is subjected to binarizing processing, a signal typing no dot is outputted to a recording apparatus because the image density signal is converted to '0'. The output gamma-correction table (a) outputs an input image signal as an output image signal as it is.

Title: Rotary head assembly
Inventor: NAKAGAWA TORU
IPC: G11B5/53
Filed: 1987-11-16
Abstract: PURPOSE:To evade wear of a head due to a tape to secure the video output in tape entrance and exit sides by projecting a face pressure adjusting part by an extent equal to or smaller than the extent of projection of a magnetic head. CONSTITUTION:In a part of a rotating member 13 in the vicinity of a magnetic head 14, a face pressure adjusting part 16 which has a coating layer having a relatively small extent of specific wear on the surface is projected by an extent equal to or smaller than the extent of projection of the magnetic head 14. The coating layer of the face pressure adjusting part is brought into contact with the tape in the vicinity of the magnetic head in the initial stage of wear of the head to relax the excessive pressing force which acts on the heads as a face pressure by the tape. According as wear of the head is advanced to reduce said pressing force, the coating layer of the face pressure adjusting part is worn to cover the reduction of the pressing force acting upon the head. Thus, head touch satisfactory for extension of the life of the head is attained.

Abstract: PURPOSE:To form a low-noise, high-speed and high-sensitivity avalanche photodiode (APD) by a method wherein an InP and InGaAs doping superlattice of graded energy-band structure is used as an electric-field limiting layer. CONSTITUTION:A buffer layer 2, a light-absorbing layer 3, an InP and InGaAs superlattice 5, an N<-> InP layer 6 are grown in succession on a substrate 1. Then, after Cd has been diffused at a low temperature and a guard ring 7 has been formed, a main unction 8 is formed by selective thermal diffusion of Zn. A passivating film 9 is a three-layer structure of PSG/SiO2/SiN; an antireflection film 10 is composed of SiN. Lastly, a P-type ohmic electrode 11 and an N-type ohmic electrode 12 are formed. A carrier generated in the light-absorbing layer 7 passes through an electric-field limiting layer, is avalanche-multiplied inside a carrier-multiplying layer and reaches a P-N junction. Because an InP and InGaAs superlattice is used as the carrier-multiplying layer, the ratio of an ionization factor for an electron and a hole becomes big and the S/N ratio is improved.
