Title: Regulated power supply circuit
Inventor: MORI SHINTARO
IPC: H02M3/28
Filed: 1987-03-23
Abstract: PURPOSE:To enable a device to be worked even if input voltage is made lower than the lowest voltage of a feedback controlling circuit, by feeding the working power of the feedback controlling circuit from the side of output voltage. CONSTITUTION:Immediately after input voltage is applied to an input terminal 1, a voltage converter circuit 8 is not sufficiently worked, and potential on the input voltage side is made higher than potential on the output side. Accordingly, current flows in the forward direction of a diode 13, and a first switching circuit 9a is turned ON. In the meantime, a diode 14 is counter-biased and is OFF, and so working power is fed to a feedback controlling circuit 7 from a power feeding route 10 on the input voltage side. After that, by the voltage converter circuit 8, the input voltage is subjected to voltage conversion and the output of stabilized output voltage is directed to an output terminal 6. As a result, potential on the output voltage side of a second switching circuit 9b is made higher than potential on the input voltage side and is turned ON, and the first switching circuit 9a is turned OFF. Accordingly, working power is fed to the feedback controlling circuit 7 from a power feeding route 11 on the output voltage side.

Title: Optical fiber for detecting liquid
Inventor: ARIKAWA TORU
IPC: G01F23/292
Filed: 1987-03-23
Abstract: PURPOSE:To quickly detect liquid with high reliability for a long distance by forming a clad enclosing a core of a plastic material and offcentering the core from the center of the clad so that the thinnest part is formed to <=10mum thickness. CONSTITUTION:This optical fiber for detecting liquid has basically the structure of a step index type waveguide consisting of the core 1 and the clad 2 enclosing the core; however, the core 1 and the clad 2 are not concentrical with each other and the core 1 is offcentered from the clad 2 so that the thinnest part 3 of the clad 2 is formed to <=10mum. An increase in loss arises when the liquid contacts such optical fiber for detecting liquid and the penetrating liquid arrives at the boundary face with the core. The liquid is, therefore, detected extremely quickly with the high reliability for a long distance if light pulses are entered to the fiber and the backward scattered light is detected. The detection of the position where the fiber is immersed in the liquid is detectable as well.

Title: Switching power supply provided with dummy resistor
Inventor: YOKOYAMA HIDEO
IPC: H02M3/28
Filed: 1981-05-11
Abstract: PURPOSE:To eliminate unnecessary power consumption and to increase the efficiency, by increasing a current flowing to a dummy resistor only when the conduction width at switching is decreased. CONSTITUTION:The conduction width of a primary pulse is detected with the 2nd secondary winding W at the secondary side of a transformer T, a rectified voltage is introducted to a rectifying circuit RECIII and a comparison voltage with the voltage division of the output voltage is used for a bias voltage of a transistor (TR)TD connected in series with a dummy resistor DR. When a load current is small, i.e., the conduction width is small, the TRTD is forward- biased and conductive, and a current flowing to the dummy resistor DR is larger, a load current is increased. As the conduction width is increased, the forward bias voltage is smaller, and the TRTD is nonconductive, causing the same state that the dummy resistor DR is eliminated. That is, detects of useless power consumption during the normal operation of the power supply can be avoided.
