Title: Control system for 2-phase servo motor
Inventor: ITO TAKASHI
IPC: H02P21/05
Filed: 1985-06-08
Abstract: PURPOSE:To prevent a vibration by using a negative feedback power amplifier to prevent a DC component from superposing on a winding and harmonic waves of the second order or higher from superposing thereon. CONSTITUTION:An output from the secondary winding 3 is applied to an exciting winding 9 of one of 2-phase servo motor 8, and an output from a negative feedback power amplifier 11 is applied to a control phase winding 10. The output of the amplifier 11 does not contain DC components in a voltage and a current, and does not almost contain the second order and higher harmonic waves. Thus, it can prevent the rotor 14 of the motor 8 from vibrating.

Title: Label microphone sound pickup for audibly handicapped person
Inventor: MIHASHI HIROSHI
IPC: H04R1/00
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To allow a person wearing an artificial inner ear to improve hearing of a phone call to the utmost. SOLUTION: In order to improve hearing of a phone call, a label microphone that is usually less used is set to a receiver 4 of a telephone set by using a suction cap 1 with a rubber band 3. Then a person can hear the phone call clearly without a noise as if the sound volume of the phone call were increased. This method allows the improvement by 90% in the case of a conversation with a person (wife) to whom the person frequently converses. There is an individual difference in hearing among people wearing an artificial inner ear so that the percentage of the improved hearing cannot be asserted, but this method at least improves the present state of hearing.

IPC: F16F15/02
Filed: 1989-05-18
Abstract: PURPOSE:To enable the damping of a vibration with a single absorber in each vibration mode of a plurality of resonance frequencies of a machine construction body by applying the constitution wherein a material having mass displacing as a rigid body during a vibration and another material having viscosity and elasticity for supporting the aforesaid material are so mounted so to have different elasticity and viscosity depending upon the direction of the vibration. CONSTITUTION:The weight of mass 2 is changed via the replacement thereof with a metal material having different specific gravity so that when a machine construction body is generating a bending vibration at a resonance frequency of Fx in the X-axis direction of rectangular coordinates set for the body, due to its own vibromotive force or an external vibration, a resonance frequency fx acting in the X-axis direction of a kinetic viscosity absorber will resonance with the frequency of Fx. Also, the volume of the mass 2 is changed to increase or reduce the weight thereof. Or the hardness of a visco-elastic material 3 such as butyl rubber is changed, or the thickness, area or the like thereof is changed to alter viscosity, thereby enabling the damping of the vibration of the machine construction body. Furthermore, for the bending vibration of the machine construction body at a resonance frequency of FY in the Y-axis, the mass 2 and the material 3 are rectangular parallelopiped to be anisotropic and a resonance frequency fr acting in the Y-axis is made to agree to the FY, thereby obtaining a vibration damping effect.

Filed: 1995-05-24
Abstract: PURPOSE: To minimize the lowering of photosensitivity due to coloring with carbon black, that is, the reduction of photoelectric current and to ensure sufficiently high photosensitivity in the region from visible light to near IR by specifying the acid value of a fixing resin. CONSTITUTION: A fixing resin, a photoconductive material, a sensitizing dye and carbon black as a colorant are incorporated and the acid value of the fixing resin is regulated to 0-5.5. That is, a resin having an acid value of 0-5.5 can be used as a fixing resin used in this black photosensitive toner. An acid value of >5.5 is not preferable because photosensitivity lowers. The fixing resin is, e.g. styrene resin, acrylic resin, styrene-acrylic resin, polyamide resin, polyester resin or butyral resin and two or more kinds of such resins may be used in combination. A cyanine dye having its max. absorption in the 650-800nm wavelength region is preferably used as the sensitizing dye.

Filed: 1982-07-20
Abstract: PURPOSE:To make the operation of visual field setting in an electron microscope performable in a speedy and easy manner, by setting up an instantaneous selector mechanism for both field shifting cases, one using an electron beam deflecting device and the other using a mechanical sample movement. CONSTITUTION:A sample 1 is irradiated by electron beams 3 emitted out of an electron gun 2 through a converging lens 4 in a state of being paralleled. Deflecting electrodes 18X and 19Y lead the electron beams, transmitting a specific spot of the sample 1, into an optical axis in an image formation system below intermediate lenses, and forms an image on a phosphor plate by the way of supplying each of two-step deflecting coils 20X, 21X and 20Y, 21Y, with a DC de- flecting current respectively. Information concerning the electrical field shifting stored in a memory is converted into a control signal to be fed to a pulse motor 23X for Y-direction drive use and a pulse motor 24Y for 24Y for Y-direction drive use and feeds the signal to these pulse motors 23X and 24Y. Since this conversion takes place so as to accord with direction and quantity of the field shifting by the electrical field shifting and the sample's mechanical shifting, a visual field on a phosphor plate 8 before and after pressing an S button is kept ever so constant except for a short time immediately after pressing the S button.

Title: System and method for compensating distribution
Inventor: TANAKA TOSHIKI
IPC: H04B10/29
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of transmission characteristics while reducing the amount of wavelength distribution compensation at a reception terminal station by dividing a transmission line into plural blocks, providing a distribution compensator for compensating the distribution of a specified wavelength, and practically turning the distribution into zero at the terminal of a receiver concerning the specified wavelength. SOLUTION: The signal light of (n) waves are multiplexed by a transmitter and branched through the transmission line by the receiver. On the transmission line, a distribution compensation fiber(DCF) is introduced for compensating the distribution at the interval of a block for several distribution shift fibers(DSF). In respect to the central wavelength of distribution in the signal light wavelength, the distribution compensation amount of DCF to be used for that distribution compensation is not turned into zero for each block but the final residual distribution amount of the receiver is constituted closer to zero.  At the time of wavelength multiple communication, since the residual distribution to be compensated at the reception terminal station is made close to zero by the central wavelength, the other wavelength is distributed with zero as a center as well and the amount of distribution compensation on the side of reception can be reduced.
