Title: Proximate distance measuring method for double tubes
Inventor: YONEMURA YASUSHI
IPC: G01B7/00
Filed: 1995-02-28
Abstract: PURPOSE: To obtain a proximate distance of double tubes by using the difference between the maximum magnetic flux leakage value and the minimum magnetic flux leakage value as a parameter, and using the graph of the (proximate distance)/(magnetic flux leakage value) known beforehand. CONSTITUTION: The inner wall of a conduit is sequentially magnetized in the circumferential direction. The value of the magnetic flux leakage at the respective point of the inner wall is measured. Then, the maximum magnetic flux leakage value BH and the minimum magnetic flux leakage value BL are taken out from the magnetic flux leakage values at these measured sites. The difference ΔB between the maximum magnetic flux leakage value BH and the minimum magnetic flux leakage value BL is obtained. Then, based on one of a plurality of the graphs of (the magnetic flux leakage value)/(proximate distance), which have been given beforehand, a central point O on the side of the proximate distance axis (abscissa) is made to be the reference. A point α and a point β are set at the positions separated by the equal distance on the right and left sides.  The difference between the magnetic flux leakage value at the point α and the magnetic flux leakage value at the point β is made to become the difference ΔB between the maximum magnetic flux leakage value BH and the minimum magnetic flux leakage value BL. At this time, the point α at the position on the left side of the central point O indicates the most proximate distance, and the point βat the position on the right of the central point O indicates the most remote distance. Thus, the errors in measurements can be suppressed.

Abstract: PROBLEM TO BE SOLVED: To make a scanner small in external size and light in weight and to prevent the malfunction of the semiconductor laser by constituting the scanner so that the normal of the incident plane of the image formation optical system at the position where optical beams are made incident on the system is not matched with the optical axis of the beams. SOLUTION: When an incident plane 52 of an image formation lens 12 does not have a curvature in a sub-scanning direction, the lens 12 is installed in a tilted condition with respect to a main scanning plane and an optical axis 50 of the light beams emitted from a semiconductor laser is set so that the axis 50 is not matched with a normal 53 of an incident plane 52 of the lens 12. Thus, the light beams emitted from the laser 4 pass along the axis 50, reflected at a point B of a reflection mirror 45 and are made incident on plane 52 of the lens 12. A part of the light beams, made incident on the plane 52 is reflected in the direction of the axis 50 at the plane 52, blocked out by a lens barrel 7 and is not made incident on the laser 4.

Title: Structural body and method for gain control
Inventor: BRIERLEY PAUL ANDREW
IPC: H04B10/07
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To control a read signal amplifier gain even before acquisition of a phase or a frequency lock by obtaining a gain error value from a difference between a real value of a read signal supplied by way of an optical data carrier wave read channel and a desired value. SOLUTION: A digital multiplexer 24 gives a register 25 a multiplexer output as an envelope signal equal to either a straightened signal received at a terminal 34 or a register output signal where a terminal 36 input is reduced by way of a terminal 37 on the basis of a logical signal received at a switching input terminal 38 from a digital comparator 22. Then, a digital subtractor 26 subtracts an output signal of the register 25, that is, a signal corresponding to an envelope signal value given to a clock cycle before itself by the multiplexer 24, from an ideal desired envelope value which a control device gives to a second input terminal 44 of the subtractor 26. This subtraction result decides a difference between the envelope value and the desired envelope value, and this outputs a gain error value to a subtractor 26 output terminal 45.

Abstract: PURPOSE:To form a high-precision micropattern, by depositing a thin silicon film on a transparent substrate, selectively scanning As ion beams in a specified condition to form a desired pattern, and oxidizing the As-injected silicon layer in a water vapor atmosphere. CONSTITUTION:A 0.1-0.3mum thin silicon film is formed on a quartz or sapphire or the like transparent substrate 101 by sputtering or CVD of polysilicon or amorphous silicon. Arsenic ion beams are allowed to selectively scan the film in a desired pattern with acceleration voltage of 50-100KV to form a 1X10<15>- 5X10<16> As/cm<2> injection region 201, and a noninjection region. This substrate is treated in a water vapor atmosphere at 600-1,050 deg.C for about 20min-2hr to oxidize the silicon. The region 201 is rapidly oxidized to a depth enough for the silicon oxide film 301 to shield light, and a transparent oxide film 302 with only a slight part oxidized is formed on the region 202, thus permitting a high precision mask to be obtained.
