Abstract: PURPOSE: To match the rotation of a driving motor with the start position of a controlled object when electric power is applied, by connecting the driving motor to a correcting motor through a differential gear.  
     CONSTITUTION: When the electric power is applied, an initial condition set signal is supplied from a command unit 1 to an initial condition set circuit 20.

The pulse signal is applied to OR gates 2,5 or OR gares 3, 4. The phases of output signals of digital phase modulation circuits 6, 7 are led or delayed depending on the number of pulses applied to the OR gates 2W5. The quantities of the variations in the phases of the output singals are detected by phase difference detection circuits 8, 9. DC signals dependent on the quantities are applied to speed control servo-units 10, 11 to rotate the driving motor and the correcting motor. The output shafts of these motors areconnected to each other through an input gear of a differential gearing unit 14. Thereby, the rotation of the driving motor is matched with the start position of the controlled object 17

Title: Method and device for producing isolated or short-chain ultra-fine particle
Inventor: HAYASHI CHIKARA
IPC: B01J3/00
Filed: 1986-05-19
Abstract: PURPOSE:To efficiently produce isolated ultra-fine particles by providing many thin tubes with the front end opened to a vaporization source and the rear end communicat ing with a high-vacuum chamber in parallel in the chamber for forming the vapor of an ultra-fine particle by an in-gas vaporization method, and increasing the degree of vacuum in a vacuum chamber to a value higher than that in the formation chamber. CONSTITUTION:When vacuum vaporization is carried out in the formation chamber 1, evacuation is performed so that the degree of vacuum in the high-vacuum chamber 10 is made higher than that in the formation chamber 1. Consequently, the vapor of a material vaporized from a crucible 4 reaches the lower surface of a large-bore group 8 of thin tubes above the crucible, however, strong suction is generated in the thin tube 7, since the rear end of each thin tube 7 is opened to the high-vacuum cham ber 10. As a result, the vapor (ultra-fine particles) is sucked from the lower suction port, and rapidly drawn into the high-vacuum chamber 10 along with the inert gas in the formation chamber 1. The isolated ultra-fine particles are then accumulated in a collecting chamber 13 and collected. Since the vaporized ultra-fine particles are then sucked by the many thin tubes 7, mass production is made possible.

Title: Manufacture of tubular film, its manufacturing device and tubular film

Filed: 1988-05-10
Abstract: PURPOSE:To eliminate sags in the center and wavy edges by providing rolls for setting respective film speed after being folded, specifying the roll speed ratio and setting the film temperature as the specific relation. CONSTITUTION:Rolls A-C can be set respectively by means of nip rolls pinching from both sides. The roll speed ratio B/A and the roll speed ratio C/B satisfy 1.0<B/A<1.2, 0.8<C/B<1.0. When the line speed ratio B/A of the rolls is 1.0 or less, orientation is not carried sufficiently to leave residual distortion, while when 1.2 or more, the tearing strength in the film flow direction is lowered and not recommended. When the roll speed ratio C/B is 0.8 or less, the film winds onto the rolls, while when 1.0 or more, film stress cannot be released. When the film temperature is set as T1 before a roll B, T2 just after passing through a heating tank and T3 before a roll C, T1<T2, 5<T3<80 deg.C is established. When the temperature T2 is on the side lower than T1, the residual distortion of film is not released. When the temperature T3 comes up to 80 deg.C or higher, creases are generated in a winding raw fabric of film.

IPC: A61B3/103
Filed: 1990-04-27
Abstract: PURPOSE:To enable the measuring of an eye refraction capacity in two directions orthogonal to each other at a high accuracy by one photographing by calculating the eye refraction capacity in the two directions orthogonal to edges of two directions from a distribution of quantity of light in respective directions orthogonal to the edges of two directions of a pupil image on an image medium. CONSTITUTION:Luminous fluxes from light sources 5a and 5b are reflected on a half mirror 2 to reach an eye E to be inspected and reflected luminous fluxes on an eye ground E form a pupil image M centered on an optical axis 01 on an image medium 1 via the half mirror 2, a light shielding plate 3 and a lens 4. Then, by turning ON light sources 5a and 5b simultaneously, bias components attributed to the light source 5a and the light source 5b are contained in illuminance on a horizontal center line Lg and a vertical center line Lp, and hence, correction is performed by subtraction of this bias component, namely, a half of the illuminance at the position of the optical axis 01. Thus, a diopter Dp on a vertical center line Lp with the position of the light source 5a as reference is calculated from a illuminance ratio or a contrast at two points P1 and P2 after the correction. Likewise, the diopter Dp on the horizontal center line Lp is calculated.

Filed: 1980-08-19
Abstract: PURPOSE:To improve the deterioration of video quality when the quantized level number of memory element is reduced, by providing a nonlinear amplifying circuit which compress or stretch luminance and color difference signals respectively at the front and rear stage of an A/D and D/A converters. CONSTITUTION:A luminance signal Y processed at a luminance signal processing circuit 20 is compressed at a Y signal companding circuit 34 when the luminance is high and stretched when low. It is uniformly quantized at an A/D converter 23 and processed at a memory 25c and D/A converter 26c. The signal Y is stretched at a Y signal companding circuit 36 when the luminance is high and compressed when low, to be restored to the original amplitude. That is, the deterioration of the video quality is taken as the brightness and coarse quantization is made for higher luminance and fine quantization is made for lower luminance. The color difference signal at a color signal processing circuit 19 is made similarly at color difference signal compressing and stretching circuits 33a, 33b, 35a, 35b depending on the color saturation degree. Thus, the deterioration of video quality is improved by reducing the quantizing level and memory capacity and the cost is lowered.
