Title: Three-phase neutral clamped pwn inverter device
Inventor: YAMANAKA KATSUTOSHI
IPC: H02M7/48
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To improve the safety and the quality of the output voltage of a three-phase neutral clamped PWM inverter device by making the potential at the neutral point adjustable at over-modulating time, by compensating the phase output terminals of three phases out of eight switching states with six switching states except two switching states by simultaneously connecting the output terminals to a positive or negative bus. SOLUTION: The time of a three-phase output voltage at which six switching states in which a positive bus P, a negative bus N, and a neutral line O are respectively connected to phase output terminals of three phases 1 is suppressed to a first set value or lower. The deficiency of the output voltage of a three-phase neutral clamped inverter device caused by the suppression of the time can be compensated with six switching states except two switching states, by simultaneously connecting the phase output terminals of the three phases 1 to the positive or negative bus P or N out of the eight switching states, in which each of the phase output terminals is connected to the positive or negative bus P or N.  Therefore, the safety and the quality of the output voltage of the inverter device can be improved, because the fluctuation of the neutral potential can be suppressed and, in addition, the neutral potential can be adjusted at over-modulating time.

Abstract: PURPOSE:To prevent overcharge and reduced electrolyte in a battery, even under any condition, by detecting the quantity of gas generated during charge. CONSTITUTION:An in-battery pressure sensitive switch 31 is formed to open/ close in response to gas pressure in a battery. On the other hand, an alternator 21 controls output voltage with a regulator 22 to regulate a current in a field coil 23. When the output voltage tends to be higher than a preset value, the voltage of the regulator 22 rises at an (a) point for a transistor 24 to decrease a current in the coil 23 so that the output voltage of the alternator 21 drops. When the output voltage of the alternator is lower than the preset value, reverse action makes it at the preset value. When the peripheral temperature of the regulator 22 is higher, the voltage of a Zener diode Dz drops for a transistor Tr1 to move to an ON state and for the transistor 24 to decrease a current in the coil 23 so that the output voltage of the alternator 21 drops.

Title: Detecting method for defocusing quantity
Inventor: TAMADA KAZUMASA
IPC: G02B7/28
Filed: 1987-09-18
Abstract: PURPOSE:To detect the defocusing quantity of a photographic lens with high accuracy by calculating the difference between object information when auxiliary light is used and object information when not, calculating the defocusing quantity from the object information at the time of the auxiliary light and performing correction with a specific correcting quantity which cancels the movement quantity of an image formation position. CONSTITUTION:An image of an object is formed by a focus lens group 20A and formed on an image pickup surface through a master lens group 20D. Then when the photoelectric output waveform of a CCD line sensor 32 to the object image deviates, the defocusing is detected from the quantity and direction of the deviation. The object information obtained from a sensor for focus detection when the auxiliary light is used, is mixed information containing the information obtained when the circumferential light is used, so the object information at the time of the use of only the circumferential light is also detected and subtracted from the mixed information to perform the correction by using the specific correcting value for canceling the movement quantity of the image formation position of the photographic lens, thereby finding the defocusing quantity at the time of the use of the auxiliary light. Consequently, the defocusing quantity of the photographic lens is detected with high accuracy regardless of the quantity of the circumferential light.
