Title: Rolling method using round die
Inventor: IGAWA MASAHARU
IPC: B21H5/02
Filed: 1983-05-11
Abstract: PURPOSE:To obtain a rolled product having good finish accuracy by setting the contact start end of a round die having a narrow set tooth width with a material to be rolled on the side inner than that of the other round die in the axial line direction of the material. CONSTITUTION:The tooth width L with one round die 10 is wider than the tooth width W of a material 3 to be rolled and therefore the die starts to mesh with a material to be rolled from the end thereof in the axial line direction of said material. The other round die 11 and the material 3 to be rolled start meshing with each other on the side inner than the end thereof in the axial line direction of the material 3. The waviness arising from the fluctuation in the number of the meshing teeth and the meshing point resulted from meshing of the other round die 11 with the material 3 is the waviness deviated by 1/2 in phase. The crest parts in the waviness generated in the tooth trance direction on the tooth surface of the material 3 are therefore successively crushed, by which the error of the tooth trance on the tooth surface is corrected and the accuracy is improved.

Title: Apparatus for detecting pattern
Inventor: HIROI TAKASHI
IPC: G01B11/24
Filed: 1994-04-21
Abstract: PURPOSE:To correctly detect a pattern of an LSI wafer or the like which is turned to be fine with a large step difference. CONSTITUTION:A pattern is projected by a projecting pattern mask 2. The contrast of the pattern is detected by focal point-detecting sensors 5a and 5b via pattern-detecting masks 4a and 4b arranged before and after a focused position. The height of an object is controlled based on the signal. Accordingly, the pattern is always detected at the focused point by a pattern-detecting sensor 8. At this time, the mask 2 and focal point-detecting sensors 5a and 5b are arranged and moved on the same stage to bring about an offset at the pattern- detecting sensor 8 to the focused position. As a result, the pattern which is made fine with a large step difference can be focused at high speeds. Moreover, the offset, of the focal point is effective to detect the pattern correctly.

Title: Fm demodulator
Inventor: FUKUOKA NOBUHIRO
IPC: H04B1/26
Filed: 1992-03-04
Abstract: PURPOSE:To obtain a PLL-FM demodulator by which the sensitivity of an FM receiver is set high by eliminating noise from an FM signal and demodulating the resulting signal. CONSTITUTION:An FM signal inputted to an input terminal 1 is inputted to a mixer 4 via a subtractor 2 and a limiter 3. The mixer 4 compares a phase of an input signal with a phase of an output signal of a pi/2 phase shifter 8 to detect a phase error. It is smoothed by an LPF 5 and extracted from an output terminal 12 as an FM demodulation signal via an amplifier 6 and used for a control signal of an oscillating frequency for a VCO 7 and an output of the VCO 7 is subject to pi/2 phase shift by a pi/2 phase shifter 8 and the result is inputted to the mixer 4 and mixers 9, 11. The mixer 9 uses an output signal of the pi/2 phase shifter 8 to apply synchronization detection to an input FM signal and an amplitude of an orthogonal component of noise is detected through an LPF 10. The mixer 11 is used to multiply the output signal of the pi/2 phase shifter 8 again with the output signal of the LPF 10 to obtain an amplitude modulation signal. Then the amplitude modulation signal is fed back to the subtractor 2, in which a phase fluctuation component is eliminated from the input FM signal. Furthermore, the amplitude fluctuation component is eliminated by the limiter 3.
