IPC: G01J1/04
Filed: 1993-03-09
Abstract: PURPOSE:To easily adjust first and second reflection mirrors without requiring sufficient space at the other side of an object to be measured. CONSTITUTION:An illumination light 4 applied from a line-shaped light source 10 provided at one side of an object 2 to be measured is retracted to illumination light with a small spread angle by a cylindrical lens 11. A first reflection mirror 12 bends the light path of the illumination light and a second reflection mirror 13 further bends the light path of the illumination light. Then, the illumination light reflected by the second reflection mirror 13 enters an image-forming lens 14 via the object 2 to be measured and further forms an image on the light-reception surface of a line sensor 15. Therefore, when adjustment deviation occurs in the first and second reflection mirrors 12 and 13, reflection light being applied to the object 2 to be measured is shifted in parallel for normal reflection light being applied to the object 2 to be measured.

Title: Producing device of standardized tape for control of drop-out correction level
Inventor: ISHIBASHI YOICHI
IPC: G01N27/72
Filed: 1985-04-08
Abstract: PURPOSE:To attain production of a tape through a simple VTR for reduction of cost by controlling continuously the degree of demagentization with detection of the level of the drop-out obtained from a demagnetizing means. CONSTITUTION:A magnetic tape 12 recorded previously by an optimum recording current travels through an erasion fixed head 13 and undergoes the normal reproduction via a video head drum 11. The RF signal obtained from a video head attached to the drum 11 is amplified by a video head amplifier 14 and turned into a waveform (a). This waveform (a) undergoes a shaping process through a DO level detecting circuit 15 to be turned into a waveform (b) and produces a waveform (c) in the form of the DC voltage showing the drop-out degree of the DO. This DC voltage drives an erasion current control circuit 16, and a current is supplied to an erasion fixed head 13. Thus the demagnetization is carried out in the lengthwise direction of the tape running through the gap part of the head 13. Then the DO shown by the waveform (a) is produced. Thus the DO produced by demagnetization are detected simultaneously and the erasion current is controlled so that the level of the DO is always constant against the set value.

Abstract: PURPOSE:To reduce the fixing man-hours of a soft material by a method wherein the soft material is pressed into shape after being bonded with an iron foil and the resultant press-molded soft material is fitted to a resin injection mold so as to mold integrally with resin material. CONSTITUTION:The skin material 2 of an interior trim 1 consists of an iron foil 4 and a soft material (tricot fabric, polyvinyl chloride leather, polyvinyl chloride sheet or the like) 3, which is shaped after being bonded with the iron foil 4. After that, the skin material 2 is pressed into a desired shape and trimmed by cutting off its unnecessary portions. Next, the skin material 2 is fitted to a resin injection mold 7 so as to inject resin material 9, which forms the main body of the interior trim. Because the iron foil has higher rigidity and better formability than aluminum foil, the skin material consisting of the soft material and the iron foil is formed easily. In addition, because the resin material to form the main body of the interior trim is injected to said skin material, the whole man-hours for the interior trim is remarkably reduced.
