Patent JP-H02177677-A (JP)
Title: Image pickup signal processor
Inventor: NAKURA RIICHI
IPC: H04N5/335
Filed: 1988-12-27
Abstract: PURPOSE:To diminish a fringe pattern by obtaining a first output signal by passing the multiplex synthetic signal output of odd and even picture element outputs through a band-pass filter, executing the multiplication operation between the first output signal and a signal having the same frequency as that of a transfer clock signal, and executing the subtraction operation between a signal obtained by passing the multiplied result through a low-pass filter and the odd and even picture element outputs. CONSTITUTION:A signal output in which the odd and even line outputs of a multielement one-dimensional CCD 1 are multiplex-synthesized is supplied to either a band-pass filter 11 to repeatedly pass a frequency component through itself for every picture element or a circuit to obtain the difference signal between an odd line and an even line. The signal having the same frequency as the transfer clock signal to drive the charge transfer part of the CCD 1 and either the band-pass filter output signal or the difference signal output are applied to a multiplier circuit 13 and made to execute the multiplication operation. The multiplier circuit output is made to execute the subtraction operation with either the odd and even picture element outputs or an even picture element output by passing the output of the odd picture element of the one-dimensional CCD 1 and the output of the even picture element of the CCD 1 through a low-pass filter 14 and respectively feeding back the respective outputs. Thus, the pattern can be completely diminished.

Title: Hub bolt position detecting device
Inventor: MUKUMOTO TAKATSUGU
IPC: B60B29/00
Filed: 1990-11-30
Abstract: PURPOSE:To enable accurate detection of the position of a hub bolt by firstly detecting the central axis of a hub through a process of bringing a first detecting section in contact with the side face of the hub and then detecting the rotational angle at the time when a second detection section is turned round to come in contact with a hub bolt. CONSTITUTION:When a hub 84 on which a wheel is to be mounted is carried to the front of a hub bolt position detection device 10 so that a hub face 86 comes to the position of the opening of a panel 26, measuring pieces 30a, 30b of a first detection section 12 are moved inward in radial direction with the action of a cylinder so that they come in contact with the peripheral face of the hub. A measuring piece 34 is also moved to left on a guide 32 so that it similarly comes in contact with the hub peripheral face. The approximate center of the hub 84 is thus detected from the outputs of encoders provided to the measuring pieces 34,30a, respectively. An engaging section 14 is moved toward the hub face 86 by means of a cylinder 90, so that the tip of a hub bolt 88 hits a taper at the tip of an inner cylinder 38. Thereafter detection member 62 is then turned round, and a rotational angle is thus measured from the output of an encoder 80 at the time when the detection member 62 comes in contact with the side face of the hub bolt 88.

A pulse becomes the one with a longer enable time in order of a wide operation, a mean operation and a tele-operation at the time of AF execution so that a focusing operation is executed at high speed by the wide operation.

Title: Manufacture of magnetic recording medium
Inventor: KAWAWAKE YASUHIRO
IPC: G11B5/85
Filed: 1990-11-30
Abstract: PURPOSE:To make it possible to obtain a magnetic recording medium having a high C/N ratio from a low recording density over to a high recording density by treating the surface of a macro-molecular base by an ion beam and by forming a magnetic layer at a specific surface temperature. CONSTITUTION:A macromolecular base 1 is treated first on the surface of a cylindrical can 4 by an ion beam 8 emitted from an ion gun 7. Next, metal evaporation atoms 12 flying from an evaporation source 11 held in a crucible 10 react with a gas coming out of a reaction gas introducing pipe 13, and in the process of the reaction, a thin-film magnetic layer is formed on the macromolecular base 1. At this time, the surface of the cylindrical can 4 is heated to a temperature from 80 deg.C to 170 deg.C. Accordingly, macromolecules of the surface of the macromolecular base 1 are put in an active state and come into contact with Co and O atoms, thereby the occasion of occurrence of nuclei is increased and a crystal grain is fractionized. Besides, the temperature of the base becomes high and thereby separation of Co from Co-O is facilitated. According to this constitution, a magnetic recording medium having a high C/N ratio from a low recording density over to a high recording density can be obtained.
