Title: Broadcast information display device
Inventor: TATSUNO HIYOSHI
IPC: G06F3/16
Filed: 1986-10-15
Abstract: PURPOSE:To improve the preservation properties of broadcast information by selecting the specific one out of these broadcast information and displaying it after conversion into the character data. CONSTITUTION:An information selecting means 1 compares the sound signal supplied from a receiver R with the data on an information discrimination data memory means 2 and transmits the sound signal to a voice information memory means 3 when coincidence is obtained between the sound signal and the head set phrase stored in the means 2. Thus the sound signal received from the receiver R is stored in the means 3. When the broadcast on the chosen information comes near its end and an end set phase is broadcasted, the means 1 prevents the pass of voices and stores only the desired information into the means 3. The data stored in the means 3 are converted into the character information by a sound signal/character converting means 4 and delivered to a display means 5.

Inventor: MIYAKE TOSHIHIDE
IPC: H03G3/10
Filed: 1985-10-31
Abstract: PURPOSE:To easily vary the ratio of the output current of a device to the input current by turning on and off a transistor (TR) provided in front of a TR circuit to which part of the input current is shunt and supplied, and control ling the input current to a trailing TR. CONSTITUTION:For example, the collector current Ic of a TR Q20 is less than a half as large as the input current Iin when a TR Q5 is turned off with a switching signal 1, therefore, when a TR Q9 is off. In this case, the collector potential of a TR Q7 and the emitter potential of a TR Q13 are expected to fall and the base current of a TR Q15 and the collector current of a TR10 increase. At this time, a TR Q11 is saturated and the base potential of a TR Q12 rises to turn off a TR Q14, so that a current Iin/2 flows through the TR Q10. Then, when the switching signal 1 changes and the TR Q9 turns on, the TR Q15 turns off. At this time, feedback is so provided that the collector current of the TR Q11 balances with the collector current of a TR Q8, so a current which is eight times as large as the collector current of the TR Q20 is a half as large as the input current Ic.
