Title: Optical rotation detecting device
Inventor: TAKEUCHI YOSHINORI
IPC: G02B6/00
Filed: 1991-07-05
Abstract: PURPOSE:To provide an output having a high S/N value and a low zero-point drift characteristic by setting at not more than a specific value a value obtained when the frequency of a sine wave applied to a phase modulator is multiplied by the length of a sensing coil and by the effective refractive index of fiber and then divided by the light velocity. CONSTITUTION:A first coupler 2 uniformly bifurcates light from a light source 1 and after the rays of light are transmitted through an optical system the first coupler 2 bifurcates the returning rays of light again and couples one ray of light to a photodiode 3. A second coupler 5 bifurcates light polarized by a polarizer 4 and re-couples together the rays of light being transmitted clockwise and counterclockwise through a sensing coil 6. In order to heighten the phase difference of the light which is generated in the coil 6, a phase modulator 7 gives a predetermined amount of phase difference to the light. A sine wave of a frequency fm(Hz) is applied to the light by the modulator 7 so that a value obtained when the length L(m) of the coil 6 is multiplied by the fm and by the effective refractive index of fiber used in the coil 6 and divided by the speed (c) of light (m/s) is not more than 7/100. Thereby an output having a high S/N and a low zero-point drift characteristic is obtained and cost reduction is achieved.

IPC: B23C5/00
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To sufficiently disperse cutting resistance of respective cutting edges, and to keep a rotary cutting balance by forming the cutting edges arranged in a cutter main body for rotating around the axis in an odd number, containing an unequal angle in a flute spacing angle between the adjacent two cutting edges, and providing the specific relationship. SOLUTION: In a cutter having cutting edges arranged at proper intervals in a cutter main body for rotating around the axis, the cutting edges are arranged by (n) sheets (n>=5), (n) is an odd number, and when a flute spacing angle between the adjacent two cutting edges is denoted by θi (i=1, 2,...n), the flute spacing angle θi contained an unequal angle, and an expression I and an expression II are realized.  Since the blade number is an odd number, a period related to cutting force of the respective cutting edges is reduced without being regularized by respectively setting the flute spacing angle θi so as to satisfy the expression I and the expression II to restrain resonance and vibration, and since the whole balance can be kept at rotary cutting time, even when high speed rotary cutting is performed, cutting accuracy is enhanced, so that there is no possibility of jumping the cutter.

Filed: 1982-09-25
Abstract: PURPOSE:To simplify considerably the design of a driving power source required for control by constituting a titled device in such a way that the discharge power between main discharge electrodes can be controlled by the making power of an auxiliary AC power source. CONSTITUTION:Ionization is effected around main discharge electrodes 10a, 10b by the effect of an auxiliary electrode 14 and the larger current can be conducted even if the impressed voltage between the main electrodes is low when a voltage is impressed between the main discharge electrodes 10a, 10b and 11 from a DC power source 17 and an AC voltage is impressed on the auxiliary electrode 14. The discharge impedance between the main discharge electrodes decreases if the auxiliary AC power is applied in the above-mentioned way. The DC discharge power can be controlled with the AC power by subjecting the auxiliary AC power to an amplitude modulation. More specifically, the voltage drop between the main discharge electrodes decreases with an increase in the auxiliary AC discharge power, showing a tendency toward an increase in the max. discharge current of the DC discharge. Not only the impulsive or intermittent control of the DC main discharge by on-off control of the AC power but also the analogical variable control of the main discharge power by the analog amplitude modulation of the AC power are possible.
