Title: Surface treating method of aluminum support for printing plate and device therefor
Inventor: YAMAZAKI TORU
IPC: B41N3/04
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To manufacture a support having a small stain and a favorable printing performance at low cost under the condition that the wear of a brush is suppressed by a method wherein a sand dressing is performed with a sand brush, the hair material density of which lies within a specified range at the foot part of hairs. SOLUTION: Each sanding brush 3, the hair material density of which is 40-80% at the root part of hairs, is employed. The hair material is planted to a metal channel and then fixed to a base roller or a base plate. If the hair material density is 20-40% at the root part of hairs, the pressure applied to the hairs becomes high, resulting in quick wear of the hairs or of a brush. Further, during the brushing of an aluminum support, locally un-rubbed portions are present and locally deeper recessed parts are formed due to local stronger rubbing. If the hair material density is 85% or more, at the rubbing of the aluminum support with the sanding brush, scratches with the hair material of the brush develop due to the hindrance of the entry of abrasive material.  The preferable value of the hair material density of the sanding brush is 40-80% at the root parts of hairs, more preferable one is 45-65% at the root part of hairs.

Also,  a lead switch 36 located along the wiring circuit 11 is connected on the input side of  the relay 15. If the electromagnet is constituted as above, the magnetic flux when the  movable core of the electromagnet is attracted has a large consumption percentage at  a large air gap, the magnetic flux density of the core can be reduced, the core is  saturated as the air-gap becoming smaller due to the attracted movable core, and the  leakage magnetic flux is rapidly increased. Thus, the lead switch 36 is turned ON to actuate the relay 15 and the contacting piece 13 is turned OFF. A resistance 12 is inserted into the coil 11 thus to decrease the current passing through the coil 11.

Title: Bearing
Inventor: AKASAKA KENJI
IPC: F16C33/24
Filed: 1989-01-31
Abstract: PURPOSE:To eliminate nonconformity such as the seizure with a shaft due to the shortage of lubricating water by including minute hollow glass balls (microballoons) in a bearing member. CONSTITUTION:Minute hollow glass balls (microballoons) 2 are included in a bearing member made of resin or the like for constituting a bearing. Thereby, since the upper parts of the minute hollow glass balls 2 projected on the surface of a bearing 1 are previously machined or scraped off by the wear due to sliding motion with a shaft 3, water 5 intrudes into the interior thereof, and when lubricating water is short, the intruded water 5 acts as lubricating water 4 for the bearing. Thus, even in a bearing 1 liable to cause a boundary lubricating condition or shortage of lubricant, seizure with the shaft 3 or occurrence of abnormal sound can be eliminated.

Abstract: PURPOSE:To make the exact measurement of an MTF value by intermittently making the images from a chart plate incident on an optical element to be detected, discretely storing the signals of the intermittent images received by a solid-state image pickup element and subtracting the stored signals. CONSTITUTION:The chart plate 3 is illuminated by a light source 1 and the luminous flux 5 emitted from the plate 3 is imaged by the optical element 4 to be detected on the solid-state image pickup element 6 which outputs an electric signal 16. The MTF of the element 4 can be measured by the Fourier transform of the signal 16. A shutter 2 is disposed for the purpose of the intermittent incidence of the images from the plate 3 on the element 4. The output of the element 6 is, therefore, converted to the electric signal 16 of the intermittent images. The timing for opening and closing the shutter 2 is used to discretely store the electric signals at the time of image shut-off and image incidence to memory elements 10, 11. The storage contents at the time of the image shut-off include a dark current, etc. The storage contents at the time of the image incidence include the luminous flux 5 emitted from the chart plate 3 in addition to the storage contents at the time of the image shut-off. The dark current- component, etc., are removed by subtraction 12 of the electric signal at the time of the image shut-off from the electric signal at the time of the image incidence.
