Title: Dc-dc converter with insulated return circuit
Inventor: KIKUCHI TOSHIO
IPC: H02M3/335
Filed: 1980-10-17
Abstract: PURPOSE:To obtain a precise converter which performs a quick response using a simple circuit by a method wherein in the rectified output of the main transformer is used as a power source, and an oscillation device is consisted of a multivibrator which is driven by the rise or fall of AC output of the main transformer. CONSTITUTION:A square wave in proportion to secondary voltage can be outputted by the FF12 which will be set or reset by the output phi1 and phi2 of the main transformer 2 using the secondary side output voltage as source voltage. In other words, the setting and resetting of input of the FET12 is triggered by each positive voltage section of the output phi1 and phi2, the continuity angle of which is controlled by the main transformer 2, and outputs Q and Q' are obtained. On the other hand, the outputs phi1 and phi2 are rectified by a rectifying and smoothing circuit 3, and as this output voltage is used as the power source voltage VDD and VSS of the FET, the output voltage Q and Q' is modulated by the secondary side output voltage. Accordingly, a precise insulated type converter, which response quickly using a simple circuit, can be obtained.

Title: Motor paraglider propulsion unit
Inventor: HAGIWARA MAKOTO
IPC: F16D35/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To reduce a torsional vibration acting on the propeller drive shaft of a motor paraglider propulsion unit. SOLUTION: A propeller 8 is held on bearings 12 and 13, so as to be freely and relatively rotatable for a drive shaft. Thus, the drive shaft 7 as well rotates relatively for the propeller 8. As a result, when the drive shaft 7 is driven and caused to rotate relatively for the propeller 8, a first plate set 26 as well as a second plate set 27 rotate relatively for each other, and a viscous resistance force attributable to the viscosity of a highly viscous fluid sealed into an operation chamber 24, is generated between the first and second plate sets 26 and 27. A driving force having such a magnitude as equal to the viscous resistance force is consequently transmitted from the second plate set 27 to the first plate set 26, or from the drive shaft 7 to the propeller 8.  Concurrently, a relative rotation vibration between the drive shaft 7 and the propeller 8 is attenuated through the viscous resistance force, thereby lessening a torsional vibration acting on the drive shaft 7.

Filed: 1995-06-13
Abstract: PURPOSE: To dissolve such problems as uneven potential distribution on wirings of electronic emission part in matrix wiring mainly applied to a picture display device, variation of electronic emission efficiency depending on picture element, spars luminance of a picture due to current flow into unselected element, and uneven electronic emission of a single element due to a displayed pattern. CONSTITUTION: Reactive element current flowing in an unselected element is measured by current monitor circuit 115 beforehand. In the case of displaying a picture, a constant current outputted to each column wiring is decided by adding the current outputted to the selected element to the reactive element current and is outputted to each column wiring by using V/I converter 112. In the case of displaying a picture, the electronic-emission efficiency is measured by the current monitor 115 beforehand and then the constant-current to each wiring is decided by being compensated with the electronic-emission efficiency. In the case of displaying a picture, the voltage on each column wiring is always measured and fed back by flowing the constant current into each column wiring. The voltage across selected elements is maintained constant by adjusting the constant-current for each feedback.
