Title: Driving method for power transistor
Inventor: MAEDA SHIRO
IPC: H03K17/78
Filed: 1987-12-18
Abstract: PURPOSE:To drive a power transistor with the small number of parts by suitably selecting the load resistance of a photocoupler, obtaining difference in the delay time of the rising and falling of a switching and generating a dead time. CONSTITUTION:An A point is changed from an L to an H, a photocoupler PC is delayed only by a toff and changed from an ON to an OFF. When the A point is changed from the H to the L, the photo-coupler PC is delayed only by a ton and changed from the OFF to the ON. By the switching of the coupler PC, following switching transistors Q1-Q4 and a transistor Tr for power are successively switched. As a result, the Tr for power is delayed only by the time toff and turned on. Then, it is delayed only by the ton and turned off. Since a load resistance (R1+R2) is selected for these ton and toff so that the condition of ton<toff can be obtained, the ON pulse width of the Tr is caused to be narrow only by toff-ton and this goes to be a dead time td.

Abstract: PURPOSE:To obtain a communication equipment for a telephone set which is easy to operate, never used by stealth, and composed of a small simple structure by providing a specific key, a code preparing means, and a tone signal output means for a transmission part and providing a tone signal receiving means and a displaying means for a reception part respectively. CONSTITUTION:When the specific key composed of an ID key, a stock key, an ordering key, etc., is pressed at a key input part 51, the key signal is latched onto an input port 74 of a microcomputer 70. When a CPU 71 discriminates that the pressed key is the ID key, the CPU 71 takes in a corresponding code from an ID code preparing part 80 and outputs the corresponding code to a tone signal modulating part 53. The modulating part 53 converts this code into a tone signal and sends the tone signal through a speaker 55 to a transmitter 30b of a handset 30. On the other hand, a tone signal from a telephone set 30a is converted into digital data at a tone signal demodulating part 62 through a microphone 61 and sent to the computer 70. A driving circuit 63 converts a digital signal outputted from an output port 75 into a driving signal and makes an indicator 64 execute a prescribed displaying. Thus, data communication can be executed while displaying data.
