Title: Driving device for speaker
Inventor: YAMAZAKI HIROSHI
IPC: H02M7/48
Filed: 1992-12-14
Abstract: PURPOSE:To largely improve nonlinearity equal to or less than VIN (th) due to the structure of a speaker by impressing input equal to or more than VIN (th) capable of moving a diaphragm even at the time of minimum input to the speaker as carrier waves. CONSTITUTION:An oscillation frequency is determined by both a resistor RT and a capacitor CT and a pulse width, that is, a modulation degree, can be controlled independently by a dead time comparator DC or by a PWM comparator PC respectively. In the case of controlling by the comparator DC, transistors TRs T1 and T4 are simultaneously turned on and off by the frequency of the carrier wave, also contrary, the TRs T2 and T3 are simultaneously turned on and off by the frequency of the carrier wave and pulse width modulated output is impressed to both ends of the speaker SP. Since a filter for interrupting the carrier wave is not inserted between the SP and the connection point of the output terminals TRs T1 and T2 and the connection point of the TRs T3 and T4, the carrier wave decided by the inductance of the SP, the frequency of the carrier wave and a power-supply voltage VS is impressed to the SP as bias at all times. Thus, the speaker responds in wide range input.

Title: Method for controlling image forming device
Inventor: UNEME KAZUHIKO
IPC: G03G15/20
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To shorten the warm-up time by displaying an image forming permission signal based on ambient temperature detected just after turning on a power source and the temperature of a fixing roller detected when a specified time has passed after turning on the power source. SOLUTION: Since the temperature of the fixing roller when the time t2 has passed, reaches lower limit temperature T1 even when the ambient temperature is the lowest temperature within a 1st temperature range R1, it is possible to form the image and image forming permission is displayed. By setting the 1st specified time t1 shorter than the time t2, the temperature of the fixing roller when the time t1 elapses reaches the temperature within a 3rd temperature range R3.  If the ambient temperature is within the range R1 at the time of turning on the power source and the temperature of the fixing roller is within the range R3 at the time t1 before the time t2, it is predicted that the temperature of the fixing roller reaches the lower limit temperature T1 at the point of time t2 when the time (t2-t1) elapses from the time t1, so that the image forming permission signal can be displayed on a display unit when the time t2 has passed.
