Abstract: PURPOSE: To detect the position of defects, by covering over  a logic printed board a mask corresponding to the kind of defects of vehicle and by checking the circuits on a flow chart in accordance with the light-on/off indication of luminescent diodes provided at check points on the mask.  
     CONSTITUTION: When the vehicle does not work, the mask 41 is taken out from a mask file. Overlapping the mask on another mask on the logic printed board 21, only the light-on/off indication of the luminescent diodes ED1, ED4WED6 can be seen through the mask 41. Namely, the diodes ED1, ED4WED6 are all lighted on. If a luminescent diode is found lighted off when a full line on the flow chart is traced from DSF, a dotted line is thereafter traced. As a result, a printed circuit board S could be found defective.

Abstract: PURPOSE:To decrease adhesion of stains and to prevent deterioration in electromagnetic conversion characteristics by providing very small recessed parts to at least a part of a resin to be used as a fixing material where said resin comes in contact with a magnetic recording medium. CONSTITUTION:Hollow granular materials 7 are packed into an epoxy resin to form the fixing member 4 and after this material is cast into a shielding case 3 and is cured, the very small recessed parts 6 are formed on a sliding surface by grinding the front face of a magnetic head.

IPC: G02B6/28
Filed: 1982-07-20
Abstract: PURPOSE:To apply external force to a base body and to vary the ratio of the quantities of branched light of projected light by using an elastic body for the base body of an optical branching device which is provided with light guides for branching incident light into plural projected light beams. CONSTITUTION:The incident light A is branched into projected light beams B1 and B2. The base body 2 is formed of the elastic body like Si rubber. External force F is applied to this optical branching device to deform the base body 2, and consequently a light guide 1 also deforms. The projected light beams B1 and B2 are equal in the quantity of light before the external force F is applied, but the application of the external force F causes variation in branching angle theta and also causes a shift in the relative positions of the light guide part 1a up to a branching point O and light guides 1b and 1c from the branching point O to light projection ends. Therefore, the ratio of the quantities of the projected light beams B1 and B2 is varied easily only by applying the external force F to the base body 2.
