Title: Paper feeder
Inventor: ISHIZU HISAO
IPC: B65H3/46
Filed: 1981-03-02
Abstract: PURPOSE:To enable to prevent sheets of paper from being fed stuck together by bringing the lower end of a separating plate into contact with the upper end of a gap adjusting screw. CONSTITUTION:The front end of the upper surface of a bundle 1 of sheets is pressed against a paper feeding pulley 12 constantly with a predetermined paper feeding pressure by the force of a paper feeding spring 11. When the pulley 12 is rotated in response to a paper feed signal, the uppermost sheet of the bundle 1 is moved forwardly by the friction between the sheet and the pulley 12, the tip of the sheet presses against the tip part of the upper end of the separating plate 13 which is slanted at about 45 deg., thereby depressing the plate 13 downwards to form a gap between the plate 13 and the peripheral surface of the pulley 12, and the sheet is fed forwardly by passing therebetween. Thus, the lower end of the plate 13 comes into contact with the upper end of the gap adjusting screw 18, whereby the fall amount is restricted so that the gap between the pulley 12 and the plate 13 does not exceed the range of from the thickness of one sheet and that of  two sheets. Accordingly, the sheet can be prevented from being fed stuck together.

Title: Surface internal measuring method
Inventor: SUGISHIMA KENJI
IPC: G01B11/14
Filed: 1987-02-10
Abstract: PURPOSE:To enhance measuring accuracy, by a method wherein beam is allowed to irradiate two surfaces having an interval therebetween and the luminous intensity distribution of the interference fringe formed on the beam receiving surface of the reflected beams from said surfaces is subjected to Fourier transformation and the frequency corresponding to the frequency length of the interference fringe is detected from the Fourier transformation data. CONSTITUTION:Laser beam is allowed to obliquely irradiate two surfaces overlapping so as to have an interval therebetween and the beams reflected from both of two surfaces are received to detect the luminous intensity distribution of the interference fringe formed on the beam receiving surface of said reflected beams and, from this detection signal, luminous intensity is converted to data so as to show luminous intensity (g) as frequency-f distribution. This frequency (f) is the one corresponding to the frequency length of X-direction distribution. Since the obtained data is dispersed in a noise component and frequency f0 to be calculated protrudes clearly as compared with other frequency, said frequency f0 can be easily detected. The interval between two surfaces can be calculated from the detected frequency f0 according to a predetermined formula. By using high speed Fourier transformation as Fourier transformation, all of a series of processings on and after the interference fringe is converted to data can be performed by a computer.

Title: Apparatus for measuring magnetic noise signal
Inventor: ISHIHARA MICHIAKI
IPC: G01R33/12
Filed: 1991-01-29
Abstract: PURPOSE:To enhance an S/N ratio and to accurately detect magnetic noise by taking out only a signal synchronous to frequency twice the frequency of the current applied to a magnetizing device from the detection signal converted to a low frequency signal. CONSTITUTION:The magnetic noise from the surface of a steel material 1 is caught along with other external noise by a detector 3. The detection signal passes through a preamplifier 6, a filter 7 and a main amplifier 8 to be rectified by a half-wave rectifier 9 and is converted into a low frequency signal by an envelope detector 10 to be inputted to a synchronous detector 11. The detector 11 uses a signal whose frequency is twice that of the magnetizing current inputted from a low frequency generator 13 as a reference signal to exclude a signal component other than magnetic noise from the detection signal and takes out only the signal synchronous to said frequency. By this constitution, external noise is reduced to a large extent and an S/N ratio is enhanced and, therefore, magnetic noise can be accurately detected.

Title: Voltage conversion circuit
Inventor: KAJIWARA NORIYUKI
IPC: H03F3/34
Filed: 1995-02-17
Abstract: PURPOSE: To improve the accuracy of voltage conversion by eliminating the effect of a current change in a current/voltage conversion circuit. CONSTITUTION: A current component of ΔI flows to a common resistor R1 between emitters of differential pair transistors (TRs) Q1, Q2 corresponding to a difference between an input voltage Vin at an input terminal 1 and a resistance V1 in a V/I conversion circuit 3. A current being a half of the current ΔI, that is, ΔI/2 flows between an emitter and a collector of a common base TR Q10 and between each collector and each emitter of TRs Q11, Q12 being components of a current mirror circuit respectively. Since a current I is supplied to a collector of the TR Q12 from a constant current source 21, a change ΔI/2 is subtracted as a cancellation current from an output buffer circuit 17. An output current change of ΔI/2 flows to a collector of a TR Q9 via a feedback resistor R2.  Since no output current change is caused from the output current of the output buffer circuit 17, a reference voltage level V3 is maintained stably.

Abstract: PURPOSE:To connect both the preceding and following strips with no fluctuation of tension, by providing a shearing machine which moves in a body with a connector at the place right before the connector and at the same time setting a path changing table right before the shearing machine. CONSTITUTION:A continuous line process is carrried out to a strip 15 of an upper-side strip supply device, and a strip 15' of a lower-side strip supply device is made to wait at a path changing talbe 7. When the coil strip quantity within a roll-out machine 1 reaches a value right before its end, the machine 1 is retarded and stopped with the end signal of a detector to stop the strip 15. A shearing machine 8 works to divide the preceding strip 15, and then both the machine 8 and a connector 9 moves in a body toward the table 7. Then the connector 9 reaches the tail end of the strip 15 and stops there. A roll-out machine 1' carries out a strip 15' as soon as the table 7 moves upward. Thus  the strip 15' overlaps the tail end of the strip 15 and stops, and both strips 15  and 15' are connected together by the connector 9.
