Title: Buffer amplifier
Inventor: ARAI MINORU
IPC: H03F1/42
Filed: 1990-07-13
Abstract: PURPOSE:To realize a highly accurate and broad band buffer amplifier by connecting 13-sets of bipolar transistors(TRs), resistors, capacitors and diodes as specified between power terminals whose polarities are opposite to each other. CONSTITUTION:A 1st bipolar TR Q1 acts like a main amplifier element. A 5th bipolar TR Q5 acts similarly like the 1st bipolar TR Q1 substantially. A 12th TR Q12 and a 13th TR Q13 supply substantially the same bias current to the 1st and 5th TRs Q1, Q5. Thus, a base bias current supplied from an input terminal 1 to the 1st TR Q1 is decreased or made zero. Through the constitution above, the input static capacitance is decreased and the input bias current is decreased or made zero, then the broad band buffer amplifier is realized.

Filed: 1981-11-20
Abstract: PURPOSE:To simplify the constitution of a repeater, by providing a single collision detecting circuit in common with two systems of transmission lines, in a regenerative repeater mutually connecting both transmission lines to which a plurality of communication terminals are connected in common. CONSTITUTION:Two coaxial cables 14A, 14B are cascade-connected with a regenerative repeater 300 and an information signal between both coaxial cables is regeneratively relayed via the repeater 300. In the normal communicating operation, when a terminal of the cable 14A transmits the information signal, it is deected at a detector 310A and given to a control section 320 to close contacts S21, S4 and the signal from the cable 14A is regeneratively relayed to the cable 14B. When the transmission is done at a terminal of the cable 14b just after the relaying, a collision detecting circuit 312 detects the change in the DC level of a core 20B via the contact S4 and gives the result to the section 320. Then, the control section 320 discriminates it as collision, restores the contact S4, changes over contacts S5, S6 and transmits a collision signal from a collision signal generating circuit 324 to the terminal of both cables.

Abstract: PURPOSE:To expand an air bag cover without delaying an air bag by providing such a constitution as never working a large load to the center part of the air bag cover, and effectively transmitting the load generated at the time of expansion of the air bag to the locking part of the air bag cover to easily break the locking part. CONSTITUTION:At the time of a vehicle collision, a gas is generated from an inflator 6, and an air bag 5 starts to expand. At this time, as the upper part of a projecting opening 9 is shielded by an expansion regulating member 3, the air bag 5 is expanded in the lower part of the projecting opening 9, or near the locking member 4 of an air bag cover 1. The load generated at the time of expansion of the air bag 5 significantly works to the vicinity of the locking member 4, whereby the locking member 4 is easily broken. The center part of the air bag 5 is prevented from being deformed by the load. Thus, the air bag 1 is immediately expanded with a hinge part 7 as the axis. Thereafter, the expansion regulating member 3 is broken from a scored part, and the air bag 5 is expanded to restrict a passenger on the assistant driver's seat.
