Title: Transformer
Inventor: HISHIKI YOSHIO
IPC: H01F19/04
Filed: 1978-04-03
Abstract: PURPOSE: To reduce common mode noise, by composing the primary and secondary windings of a conductive foil tape and depending on how to wind thereof.  
     CONSTITUTION: The primary winding L 1  and the secondary winding L 2  which are made up of a conductive foil tape are wound in such a manner that the ends of the windings as opposed to each other are equal in polarity as illustrated and the portions of the tapes on the windings as opposed to each other are grounded. When a voltage +V 1  is applied on the winding 1, a potential gradient develops therein from the earth side toward the plus side rising O to V 1  while in the secondary winding L 2 , from the earth side to the plus side rising O to V 2 . Here, the portion as opposed to each other between the primary winding L 1  and the secondary winding L 2  is equal in the potential, thus eliminating flow of common mode noise current.

Title: Double scanning type spectrophotometer
Inventor: KOIZUMI HIDEAKI
IPC: G01J3/06
Filed: 1981-03-17
Abstract: PURPOSE:To carry out accurate and effective wavelength scanning and to improve the capacity of analysis, by rotating a dispersion element and concave mirror at the same time or alternately. CONSTITUTION:A grating 5 is rotated at a regular scanning speed and a pulse motor 17 is stopped after carrying out wavelength scanning to a specified wavelength. Further, a pulse signal having a long period is sent to a pulse motor 27 and an emission side collimating mirror 6 is rotated slowly. Next, the grating 5 is rotated again to the same direction so as to carrry out the wavelength scanning quickly by a sending mechanism 10. When it is drawn near a specific wavelength, the mirror 6 is rotated slowly in several Angstrom  section. In such a manner, the analysis is made effectively by carrying out the wavelength scanning quickly between analysis spectrum lines by the grating 5 and scanning the spectrum to be an object of analysis by the mirror 6 slowly.

Title: Own vehicle speed control device
Inventor: KADAKA TAKAYUKI
IPC: B60R21/00
Filed: 1993-01-18
Abstract: PURPOSE:To secure safe inter-vehicle distance by controlling speed through the detection of the relative relation between the own vehicle state and the other vehicle state during travel. CONSTITUTION:An own vehicle state detector 1 is driven by the control signal 6 of a detection control signal generator 2 so as to detect the speed in the traveling state of the own vehicle and to send this speed to a judging element 4. An other-vehicle state detector 3 is also driven by the signal 6 so as to detect the inter-vehicle distance to the other vehicle and the speed difference between the own vehicle and the other vehicle and to send them to the judging element 4. The judging element 4 computes using the speed of the own vehicle, the inter-vehicle distance and the speed difference between the own vehicle and the other vehicle. In the case of exceeding the previously integrated limit relation, that is, the criterion of the inter-vehicle distance and speed, a speed controller 5 is driven in the direction of making the inter-vehicle distance safe. During travel, the speed is thereby controlled so as not to fall in the dangerous inter- vehicle distance and speed relation. Safe driving can be thereby performed at all times.

Title: Method for driving fluorescent display tube filament
Inventor: TONO YASUHIRO
IPC: G09G3/12
Filed: 1988-02-25
Abstract: PURPOSE:To prevent the generation of a flicker of a display even if a lighting duty in static lighting is small by specifying the frequency of an AC voltage applied to a cathode filament, and a repeating frequency for a display given to a grid and/or an anode. CONSTITUTION:A relation between the frequency f2 of an AC voltage applied to a cathode filament and the repeating frequency f1 of a voltage applied to a grid terminal and/or an anode terminal is set to f2=(n+1/m).f1, and also, f1/m is set to a frequency or above which does not flicker. In this regard, (n) and (m) are natural numbers. As a result, within the time of m/f1, the voltage between the anode and the grid, and the cathode filament is averaged, and a flicker can be prevented by setting f1/m to a frequency by which a flicker is inconspicuous. In such a way, even when the lighting duty ratio of a static lighting fluorescent tube is small, the flicker of a display is prevented.
