Title: Battery charging apparatus
Inventor: KONDO EIJI
IPC: H02P9/30
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To realize a battery charging apparatus for a bicycle, whose loss is low by a method, wherein a rectifier circuit is constituted of a Schottky barrier diode and an FET. SOLUTION: A rectifier circuit, which uses a permanent magnet three-phase AC generator ACG as an input, is constituted in such a way that Schottky barrier diodes D11 to D13 in a group are connected to the positive side and that FETs FET1 to FET3 in a group are connected to the negative side. In the FETs FET1 to FET3 in the group, a positive bias is applied to their gates when an AC input voltage is negative. Thereby, in the respective FETs, a rectifying current flows not to bodies diodes D14 to D16 but to the FETs FET1 to FET3, and a synchronized rectifying operation is performed. Consequently, a rectifying loss can be reduced. In addition, when a battery B is fully charged, the gates of all the FETs are positively biased simultaneously, respective phases of the AC generator ACG are short-circuited, and an excessive charging operation is prevented.  A short circuit formed of, e.g. a U-phase of the AC generator ACG to the FET1 to the FET2 and to the V-phase is formed by the output of the AC generator ACG at this time.

Title: Cable winding state detecting method
Inventor: YASUOKA SEIJI
IPC: B65H54/52
Filed: 1989-02-20
Abstract: PURPOSE:To detect the relative position between the axis center positions of a preceding cable and a succeeding cable by irradiating light to the cable wound while being aligned and regarding the most luminous part as the axis center position of the cable by the image information obtained by the reflected light. CONSTITUTION:Parallel rays are irradiated to the band region, parallel to the rotation axis 3a of a drum 3, of a cable 4 wound to a rotating drum while being aligned. Its reflected light is caught by a TV camera 11, and its image information is fed to an image processing system 12 on the succeeding stage. Whether or not the cable is wound in the normal aligned state is recognized by regarding the most luminous part in the image as the axis center position of the cable and obtaining the relative position relation between the axis center positions of the preceding cable and the succeeding cable wound right next to the preceding one. As a result, in case winding turbulence is generated, an alarm is emitted, and the position is controlled by changing the rotating direction of the drum 3.

Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To make rising characteristics fast and to enhance the availability of light in the case of using a small-diameter reflection type cold cathode lamp. SOLUTION: This device is equipped with a reflection type cold cathode lamp 16 provided with a valve 17 having irradiation directivity by forming a mainly reflecting insulating reflection film 18 on a part of an inner wall surface, a heater 20 provided on the outer peripheral surface of the valve 17 corresponding to only a part of the area of the reflection film 18, and a casing 21 made of heat-resistant and white resin having a reflection surface 22 to cover the reflection surface 18 and the heater 20 side of the valve 17. Thus, by energizing and properly heating the heater 20, the lamp 16 emits light in a quick rising characteristic state even when it is used under low temperature environment. The light radiated from the lamp 16 is partially transmitted through the reflection film 18. Since the heater 20 exists only at a part of the area of the reflection film 18, the light transmitted through the reflection film 18 and the valve 17 without being intercepted by the heater 20 is reflected on the reflection surface 22, so that the utilization efficiency of light is enhanced.
