Patent TW-273651-B (TW)
Title: Fixed-interval timing circuit and method
Inventor: MASAKAZU SHOJI
IPC: H03K5/04
Filed: 1995-08-03
Granted: 1996-04-01
Abstract: A system and method for generating a signal having a reliable, fixed duration and/or delay as a function of relative, not absolute, device characteristics. That is to say, the time period of the generated signal is determined as a ratio of one device's operating characteristics to another device's operating characteristics. In particular, the invention provides a fixed time signal as a function of the relative values of two capacitive elements that have a known ratio of capacitance with respect to each other. The invention is particularly useful when implemented upon an integrated circuit, as standard fabrication techniques for such circuits allow relative device characteristics to be held to relatively tight tolerances.

Title: Device for preventing overdischarging
Inventor: OGATA HIROAKI
IPC: H02P7/29
Filed: 1995-12-13
Granted: 1999-08-11
Abstract: The invention aims to provide a device for preventing overdischarging whereby, without using large capacity batteries, self-storage batteries can be prevented from overdischarging which can lead to reduction of the recycling life. In step Sb3, the duty ratio calculated in step Sb2, according to a feedback control is compared with the limit value of the duty ratio corresponding to the limit of the battery current. When the duty ratio is smaller than the limit value, the PWM wave (step Sb4) generated from said duty ratio is output. When the duty ratio is greater than the limit value, the output PWM wave (Sb5) is generated from the duty ratio obtained from the limit value. As a result, the duty ratio of the PWM wave used as an instruction for the current flow will not be greater than the limit value, and the current taken from the storage batteries can be prevented from exceeding the limit current of the storage batteries.

Title: Low drop-out power supplies
Inventor: GRIMM MICHAEL ARTHUR
IPC: H02M3/156
Filed: 1996-02-10
Granted: 2001-08-11
Abstract: A method for generating, in a switching power supply, an output voltage from an input voltage. The method includes the step of closing a switch in the switching power supply to permit current from the input source to flow through the inductor and the capacitor of the switching power supply, thereby building up an inductor current through the inductor and increasing the output voltage across the capacitor. If a combination of the output voltage and inductor current is satisfactory at the start of an off-time of the oscillator signal, the method opens the switch. If a combination of the output voltage and inductor current is unsatisfactory at the start of an off-time of the oscillator signal, the inventive method preferably keeps the switch closed past the off time of the oscillator signal to continue building up the inductor current through the inductor and increasing the output voltage across the capacitor.
