Title: Electric shock preventive circuit in electric equipment
Inventor: KANEHARA YOSHIHIDE
IPC: H03H7/09
Filed: 1995-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an electric shock preventive circuit which reduces the voltage to earth of a case when a human body touches an electric equipment which has in the case a power converter that conducts switching operations at high frequencies and a load that, being connected to the power converter, has a stray capacitance. SOLUTION: An electric equipment has a power converter and a load connected to the power converter in a box. In such an electric equipment, the primary sides of transformers 46, 47, 48 are connected between outputs U1, V1, W1 and an input earth line S2 of the power converter 2 and then the voltages at the secondary sides of the transformers are inversed. The secondary sides of the transformers to which capacitors C1, C2, C3 are serially connected respectively are connected between the input earth line S2 of the power converter 2 and the case. The currents in the capacitors C1, C2, C3 flow in the opposite direction to leakage currents in stray capacitances Cu, Cv, Cw of the load but the absolute values are the same as those of the leakage currents.  Since the sum of the currents in the capacitors C1, C2, C3 and the leakage currents in the stray capacitances Cu, Cv, Cw becomes zero, the voltage to earth of the case can be reduced and thereby an electric shock can be prevented.

Title: Fluid jet loom
Inventor: TSUNASHIMA YOSHIHIRO
IPC: D03D47/30
Filed: 1991-09-20
Abstract: PURPOSE:To provide the subject loom designed to substantially shorten working time and manhour by calculating nozzle characteristics based on the weft unwinding timing data detected while changing nozzle jet pressure and by setting the optimal picking conditions using these characteristics. CONSTITUTION:In setting the optimal picking conditions in an air jet loom, the minimal weft delivery speed is calculated from the input data of the initial values such as number of revolutions, weaving width and yarn type. Along with this, the initial pressures and timings for the main nozzle and subnozzles are set, respectively. Then, weft unwinding timing is measured while variously changing the pressure of air to be fed to the main nozzle through inching operation to set the minimal main nozzle pressure enabling weft reach, the respective jet timings for the main nozzle and subnozzles. A normal operation is then started, and if real reach timing is later than the aimed timing, the main nozzle pressure is raised to make a regulation so that both the timings get equal to each other, and under this final main nozzle pressure, subnozzle pressures are regulated in a similar manner to that mentioned above to eliminate unnecessary air consumption, thus setting the final pressures.
