Title: Testing method for insulation of light guide
Inventor: KOBAYASHI ATSUO
IPC: G01R31/12
Filed: 1980-02-08
Abstract: PURPOSE:To test securely whether a light guide has the property of insulation uniformly over its overall length in a short time, by allowing the light guide to slide and pass by two electrode arranged at a prescribed interval and at a prescribed speed and by applying a voltage in a prescribed waveform. CONSTITUTION:Light guide 1 to be tested wound around drum 3 is taken up around take-up drum 2 at a constant speed. Between spherical electrodes 4, a prescribed voltage is applied via AC variable power source 5 and transformer 6. Distance (d) between electrodes 4 is adequately determined according to voltage conditions and the performance of the secondary voltage of transformer 6. The speed of light guide 1 is determined depending upon the time required for insulation evaluation and that of the processing of a recorder. If the performance of insulation is defective during a test, it can be judged from data on recorder 11. This constitution provides insulation appreciation, i.e. evaluates dielectric strength characteristics, corona characteristics, etc., continuously under the same condition over the overall length of the light guide. Therefore, the test can be made securely in a short time.

Abstract: PURPOSE:To prevent the output error of an electromagnetic pickup caused by a magnetic substance by a system wherein a means of catching the magnetic substance in a lubricating oil is provided on the upstream side of the electromagnetic pickup in relation to the flow of the lubricating oil along the inner wall of a housing. CONSTITUTION:During an operation of CVT, a lubricating oil sticks on the inner wall of a housing 12 and is lowered along this inner wall due to a force of air generated by the gravity and an input-side pulley 10. Although iron powders or the like formed of magnetic material are contained as cuttings, wear powders or the like in the lubricating oil, the part of these magnetic substances which flows toward an electromagnetic pickup 16 is attracted in the course by a permanent magnet 22 positioned on the upstream side of said pickup 16 and is caught thereby. Therefore, it is avoided that the magnetic substances are attracted and made to stick to the electromagnetic pickup 16, and thus an output error of the electromagnetic pickup 16 due to the sticking of the magnetic substances thereto is prevented.

IPC: B65H54/84
Filed: 1985-01-28
Abstract: PURPOSE:To stabilize the winding configuration in winding up a metal wire etc. into a pack, by applying minor vibration to the pack during pack forming or after completion thereof. CONSTITUTION:A wire paid off 4 is formed into a coil by a coiler 5 and drops into a pack 1 to be accumulated thereto. A vibrator 7 is installed under a table 6 on which the pack 1 is to be placed, in order to apply minor-scale vertical vibration to the pack 1 during pack forming and the wound wire. The conditions of vibration to be applied depend upon the size of pack 1, the material, size, weight, etc. of the wire 4, preferably with amplitude ranging between 2 and 10mm and the frequency between 50 and 60Hz/s. Thus the winding configuration of the wire being packed is stabilized because of applied vibration to assure transportation without risk of collapse of pack and reduction of the likelihood of wire being cut due to entanglement during use.

Filed: 1982-02-02
Abstract: PURPOSE:To reduce the power loss of a power amplifying circuit and to increase the power efficiency for a power supply circuit of an amplifier, by actuating the power supply circuit with the voltage of a level when the signal level is low. CONSTITUTION:Now it is supposed that the signal level is low and set at¦vO- VC¦<¦VCC2¦. As a result, a power supply transistors (TR)Q3 and Q4 are turned off with diodes D1 and D2 turned on respectively. Therefore the feed is carried out to the collectors of amplifying TRsQ1 and Q2 with a low level of voltage + or -VCC2. Thus a current of¦VO+VC¦is supplied instead of¦VCC2¦. In such a way, a power supply circuit is actuated with the voltage of a low level when the signal level is low. Thus, the power loss is reduced and the power efficiency is increased.

Abstract: PURPOSE:To improve the setting efficiency by detecting an operation element being operated continuously up to the setting limit value of a parameter, further detecting the operation being carried on after the limit value is reached, and setting the set values of the parameters to mutually different values with the output. CONSTITUTION:When the operation element 20 is operated continuously to change the setting of a parameter, a limit operation detecting means 30 detects the operation reaching its limit value and an operation detecting means 31 detects the operation element being operated to normally vary the settings of a parameter setting device 32 as they are.
