Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To simply, effectively remove unnecessary light by using a spectral element whose emitting angle is different by wave length. SOLUTION: Emitted light from an undulator radiation source 1 contains harmonic X-rays, continuous X-rays, and an ultraviolet ray in addition to fundamental X-rays. Pencil-like thin beam of the emitted light is reflected and magnified with a convex reflecting mirror 2, then reflected with a concave diffraction grating 3. The beam is incident to the diffraction grating 3 at about 88 deg., only the X-rays having a wave length of about 13nm are emitted in the reflection mask 4, and most light having wave length other than about 13nm is absorbed in the grating 3 and an absorbing body 7.  By using the diffraction grating 3 having different emitting angle by wave length in an illuminating optical system, light in an ultraviolet or visible region of long wave length, emitted from the undulator radiation source 1 is reflected in the direction different from X-rays which are necessary for exposure to be separated, and drop in resolution in pattern transfer can be prevented.

Title: Angle controller
Inventor: MURATA MINORU
IPC: G02B26/10
Filed: 1988-07-08
Abstract: PURPOSE:To perform high-accuracy and high-resolution angle control with a less number of components by respectively specifying angles between a light advancing axis and the rotary axis of an optical element and between the rotary axis and the normal at point of incidence of the element and rotating the element around the rotary axis by a specific angle. CONSTITUTION:A holder 3 is arranged so that an angle alpha(not equal to 0) can be formed between its rotary axis 8 and a light advancing axis 1 and a mirror 2 is put in and fixed to the holder 3 so that an angle beta(not equal to 0, beta<alpha) can be formed between its normal at point of incident 9 and the rotary axis 8 of the holder 3. The holder 3 is directly coupled with the rotary shaft of a stepping motor 5 and the mirror 2 also rotates when the motor 5 rotates. Therefore, the decelerating ratio (rotary angle ratio) between the rotational angle phi of an optical element and the incident angle theta of light can be made extremely larger. Thus the incident angle theta can be controlled with high resolution of about several seconds with a less number of components.

Abstract: PURPOSE:To detect the abnormality with a certain precision in a short time by detecting the presence or the absence of supply and take-up reel rotating pulses and the presence or the absence of a capstan rotating pulse within a certain time on a basis of the capstan rotating pulse. CONSTITUTION:When the supply reel is not rotated, the capstan rotating pulse and the take-up reel rotating pulse come to input terminals 46 and 47 because if the tape running mode, but the supply reel rotating pulse does not come to an input terminal 48 and the input terminal 48 is held in a certain level. Consequently, a microcomputer 45 discriminates that supply reel rotating pulses do not come at all when n-number of capstan rotating pulses are counted, and the micro-computer 45 generates a tape running abnormality detection signal and outputs it to an output terminal 50. When the take-up reel is not rotated, the computer 45 discriminates similarly that take-up reel rotating pulses do not come at all when n-number of capstan rotating pulses are counted, and the computer 45 outputs the tape running abnormality detection signal to the terminal 50.

Title: Clock synchronizing circuit of multi-track type magnetic recording and reproducing device
Inventor: KATOU MASAAKI
IPC: G11B20/14
Filed: 1983-09-16
Abstract: PURPOSE:To ensure the easy control of a clock synchronizing circuit by using a voltage controlled oscillator needing control only to a clock synchronizing circuit for >=2 selected tracks, and using a phase locked loop composed of a phase comparator and a phase control circuit to a clock synchronizing circuit of non- selected track. CONSTITUTION:The output of an equalizer 13-2 is applied to a phase comparator 51, and the phase of the output of a changeover switch 35 is compared with the phase of a signal obtained through a delay circuit 52, NAND gate circuits 53 and 54, exclusive OR circuit 55 and a 1/M divider 56. When an output 57 outputs a pulse of ''1'', the circuit 54 opens to supply the output of the circuit 52 to the circuit 55. Thus the number of pulses supplied to the circuit 56 is increased by one. The divider 56 consists of a counter and receives pulses with extra one. Therefore, the output of the divider 56 advances in phase. When an output 58 outputs a pulse of ''1'', both circuits 53 and 54 are closed. Thus the pulses applied to the divider 56 are decreased by one. In such a way, the output of the divider 56 is delayed in phase.

Abstract: PURPOSE: To uniformly compress the entire part of wound yarns by connecting upper and lower annular ends and plural rings arranged coaxially therewith by spacings, disposing bridge members and constituting the same compressibly in an axial direction. CONSTITUTION: A pair of the upper and lower annular ends 10 and 11 and the intermediate rings 12 arrayed in a plurality coaxially around the longitudinal axis of a tubular body apart suitable spacings therebetween are connected by the plural spacings 13 in a transverse direction. These spacings 13 are constituted without projecting from the surface 14 of the tubular body wound with the yarns in such a manner that the tubular body may be axially compressed. Further, the breakable bridges 16 for holding the axial rigidity and controlling the compression degree between the rings 12 at the time of compression are disposed between the adjacent rings 12.

In addition, the bridges 16 act as a stopping mechanism to ensure the uniform compression.
