IPC: H02M3/155
Filed: 1994-04-22
Abstract: PURPOSE:To accurately detect a voltage between terminals in an ON state of a chopper type regulator by obtaining the voltage between the terminal in the state that the regulator is ON from a mean voltage of output terminals for a predetermined period, a duty ratio of switching and an input voltage to be applied to an input terminal.

Title: Excimer laser
Inventor: HIROUCHI KENJI
IPC: H01S3/097
Filed: 1990-03-30
Abstract: PURPOSE:To suitably select the time constants of the resistances of high and low voltage resistors and a capacitor, raising a charging voltage to be detected by an operational amplifier preferentially at timing to the actual charging voltage of a primary capacitor, and to prevent the overcharging of the primary capacitor by connecting high and low voltage capacitors in parallel with the high and low voltage resistors. CONSTITUTION:A high voltage capacitor C2 is connected in parallel with a high voltage resistor R for forming a voltage divider VS1 of a voltage monitor MC1, and a low voltage capacitor C2 is connected in parallel with a low voltage resistor (r). In a charging transient period of a primary capacitor C1, a voltage waveform obtained by adding an AC component flowing through a capacitor to a DC component flowing through a resistor is applied to an operational amplifier OP. Accordingly, when the time constant of the resistors and the capacitors is suitably selected, the charging voltage to be detected by the amplifier OP can be raised preferentially at timing to the actual charging voltage of the capacitor C1. That is, the charging voltage can be detected previously before the completion of the charging of the capacitor C1.

Title: Display method for diagnosing system
Inventor: MIYAHARA NORIO
IPC: G06F11/22
Filed: 1988-04-11
Abstract: PURPOSE:To sensibly increase the information transmission speed and to make the display easy to see by flickering or intermitting a visual or audio indicator a prescribed number of times in accordance with diagnostic information and setting a certain blank time independently of this prescribed number thereafter and discriminating and displaying a trouble position of a system. CONSTITUTION:When diagnostic information is displayed with the number of times of flicker of a lamp 4, the lamp 4 is flickered the prescribed number of times in accordance with diagnostic information and a certain blank time TB is set independently of this number of times of flicker thereafter. Since the certain blank time TB is set independently of the number of times of flicker after the lamp 4 is flickered the prescribed number of times, the blank time TB is not varied though the fundamental cycle of display is varied by the number of times of flicker of the lamp 4. Thus, since information is displayed in the shortest time when the number of times of flicker of the lamp can be visually confirmed and the blank time TB is minimized, the information transmission speed is increased and normal display and erroneous recognition are prevented.
