Title: Magnetic recording and reproducing device
Inventor: GONDO KENJI
IPC: G11B5/02
Filed: 1989-06-06
Abstract: PURPOSE:To reduce a variable resistor for adjusting a recording current and to uniformly supply the recording current to respective magnetic heads by providing constant-current circuits in respective rotary transformers and absorbing variance in the inductance of the rotary transformer and the magnetic head. CONSTITUTION:The constant-current circuits 8 and 9 are provided between earths and the ends b and c of the coils on the fixed sides of the rotary transformers 2 and 3. A recording signal outputted from a constant-current driving circuit 1 flows from one end a to the other ends b and c of the coil on the fixed side. At such a time, the recording signal is controlled to become a constant current by the constant-current circuits 8 and 9. Thus, the constant current flows in the magnetic heads 6 and 7 magnetically connected to the coils 2b and 3b on the rotating sides of the rotary transformers 2 and 3 and the magnetism recorded on a magnetic tape becomes constant, thereby uniformly performing recording on the magnetic tape without providing the variable resistor for adjusting the recording current.

Filed: 1982-08-20
Abstract: PURPOSE:To achieve the object of polishing a cylinder surface by using an exceedingly simple constitution by permitting the cylinder surface to be polished by means of the difference in the circumferential speed, while shifting a polishing wheel in parallel to a cylinder shaft. CONSTITUTION:In an apparatus for polishing the outside surface of a cylindrical article, supporting plates 2 are installed in tightened state onto both edge faces of a cylinder body 1 to be polished, and a bearing part 4 fitted onto a center shaft is loaded onto a bearing board 5, and then said cylinder body is stably supported by its dead weight, and can be freely revolved. Therefore, when the polishing wheel 9 of a hand grinder which makes contact with the cylinder body at a proper angle revolves in the direction of arrow, the cylinder body is also driven and turned while being polished, and speed is accelerated gradually. However, since said revolution is limited to nearly a fixed speed by the operation of a governor 7 which is driven in contact with the supporting plate 2, stable polishing action is developed.

Filed: 1985-07-01
Abstract: PURPOSE:To simplify a circuit structure and to improve an S/N by stopping operations of deemphasis circuits during a period having no relation to a line in case of reproducing. CONSTITUTION:When original signals a impressed in a video signal input terminal 1 are luminance signals of output levels 1 containing many high-frequency components, output signals d of subtraction circuit 6 will be wave-like signals having an output of k.

Output signals f are subtracted from the original signals a in the subtraction circuits 13 and the output signals delivered at the output terminal 10 allow their noise components to be removed during the periods having the relations to the line. In such a way, the deterioration of waveform of an output is decreased and S/N is improved without deteriorating the picture quantity.

Filed: 1994-06-04
Abstract: PURPOSE:To obtain a spectrometer being excellent in repetitive scanning properties within the range of a prescribed wavelength by a construction wherein a cam follower fitted to a rotating body is brought into sliding contact with a swinging end of a contact bar. CONSTITUTION:A light passing through an incident slit 2 is reflected on a first concave mirror 3 and cast on a diffraction grating G. The grating G rotates around an axis P and the light diffracted by the grating G is reflected 3 and detected 7. On the other hand, a light of a specified wavelength obtained by reflecting 8 the diffracted light and converging it at a slit 11 is detected 12. A cam follower 20 of a radius Rc is provided at a position being eccentric by Rof to the axis of a rotating body 19 provided at a position of a distance Lgc from the grating G and made to rotate by a pulse motor 18. On the occasion, a contact bar 14 being in contact with the follower 20 rotates by one reciprocation while the rotating body 19 rotates one time, the grating G rotates also at the same angle as the bar and thereby a spectral wavelength lambdais changed. This angle of rotation is determined by the distance Lgc the amount Rof of eccentricity and the radius Rc. Therefore the angle of rotation of the rotating body 19 is reduced and converted into a continuous reciprocating motion.

Title: Birefringence evaluation system
Inventor: TAKAWA HIROYUKI
IPC: G01N21/23
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To configure a high speed high accuracy birefringence evaluation system by picking up a birefringence image through an observation optical system as an analyzable image data using a sharp color plate method. SOLUTION: When a sample SP is inserted between a first polarizer 13 and a full wavelength plate 22, an optical signal is subjected to phase difference equal to the combined phase difference of the sample SP and the full wavelength plate 22. Consequently, the wavelength of the light subjected to phase difference is shifted from the reference wavelength by an amount corresponding to the birefringence of the sample SP. Consequently, the hue being observed is varied as the spectral transmittance of an optical signal LB passing through a second polarizer 23 varies and the birefringence can be estimated with higher sensitivity than the cross Nicol method. More specifically, a birefringence image representative of variation in the hue of the sample SP is picked up by means of a color image pickup element 24 and delivered to a data acquisition system 2.  It is presented on a display in real time and subjected to a required processing in parallel with image observation on the monitor 40, as required.
