Title: Transformer winding
Inventor: WATANABE MASARU
IPC: H01F29/02
Filed: 1978-03-17
Abstract: PURPOSE: To lower tap-generating voltage at the time of impulse voltage application by coiling the main winding around a spool cylinder into a disc form and also by coiling the tap winding around the same cylinder into a cylindrical and helical form.  
     CONSTITUTION: The main winding 3 is coiled around the spool cylinder 1 into a disc form, and then the tap winding 2 is coiled around the same cylinder 1. In the case of the tap winding, plural wires arranged in parallel are coiled helically into plural turns toward the outside diameter direction and then the upper end of the inside windings is connected to the lower end of the winding on the next adjacent outside so that they are coiled into a cylindrical and helical form. Accordingly, the tap lead can be easily taken simply by drawin out wires at the beginning of coiling and at the end of coiling, and great series static capacity can be obtained without the number of tap and the number of turns being limited because of the cylindrical and helical form, thus reducing the tap-generating voltage at the time of impulse voltage application.

Title: Sensitivity adjusting method and device for laser flow meter
Inventor: NAKAGAWA KOUJI
IPC: G01S17/58
Filed: 1978-03-17
Abstract: PURPOSE:To simplify the handling and shorten the metering time of a flow meter by automatically controlling the sensitivity of a photoelectric converter and the intensity of a laser beam while using the output signals of the element as the feedback element. CONSTITUTION:When the output voltage of a high voltage power source 14 becomes excessively low, the sensitivity of a photoelectron multiplier 12. As a result, the output pulses of discriminators 17 and 18 are reduced so that no output is generated in a pulse counting unit 19. Since a step voltage generating unit 21 receives the output of the counting unit 19 to generate positive step voltage, the power source 14 receives this to raise the output voltage. A series of these operations are repeated at the preset period of the pulse counting unit the sensitivity of the mutiplier 12 is increased to make the output level and frequency sufficient. If the output voltage of the power source 14 is excessive, the opposite operations to the above are so accomplished that the sensitivity of the multiplier 12 can be always held at a desired level. Thus, it is possible to simplify the handling of a flow meter and to shorten the measuring time.

Abstract: PURPOSE:To make it possible to use breakdown strength and current performance of a transistor effectively even if DC input largely varies by making it possible to connect an auxiliary feedback primary winding to an exciting current feedback circuit of a transformer in series in accordance with a DC input voltage. CONSTITUTION:An input voltage is covered into an AC by switching of a transistor 3, and is rectified and smoothed to input after converting into an AC by a transformer 2.

Two feedback primary windings are connected to a diode 1 through a manual switch 4, and when the transistor 3 is turned OFF, energy to be accumulated in the transformer 2 is fed back to the input side. The winding ratio between the main primary winding N21 and the feedback winding can be varied by switching the manual switch 4, and a voltage applied to the transistor 3 can't be changed too much even if an input voltage largely varies.
