Title: Automatic gain control circuit
Inventor: ROBAATO KEISU POOTOUEI GARUPIN
IPC: H03G3/20
Filed: 1980-09-12
Abstract: In high speed high quality modems it is important to be able to preserve the gain value for the automatic gain control system during breaks in transmission to permit rapid resumption of normal operation. The a.g.c. circuit comprises a basic a.g.c. transistor amplifier whose emitter-collector conductance is varied by a control voltage derived from the envelope of the amplifier output voltage which is well known. The invention involves the use of a digital-to-analog converter which is controlled by a digital-up-down counter. The counter is controlled by a window comparator which compares the rectified output voltage of the amplifier with a reference voltage level and upper and lower limits. If the output voltage exceeds either limit, the counter is enabled and the appropriate up or down indication is given. The counter is then clocked to change the drive to the d-to-a converter which thereby changes the conductance of the a.g.c. transistor. The state of the up down counter will be used to maintain the a.g.c. at the last level in the event of a transmission break by inhibiting the clock for the counter.

Abstract: PURPOSE:To permit the confirmation of connection of a battery by a method wherein the title circuit is provided with a detecting means, detecting that the secondary voltage of a transformer is lower than a predetermined voltage, and an indicating means, in the charging circuit charging through the transformer. CONSTITUTION:When a storage battery B is not connected to a charging circuit, a transistor Q1 is put ON whereby the transistor Q2 is put OFF and a light emission diode D4 is being extinguished. When the storage battery D is connected to the charging circuit, the transistor Q1 is not put ON whereby the transistor Q2 is put ON and the light emission diode D4 is lighted. When a plug 3 is pulled out of a commercial AC power source while connecting the storage battery D as it is, current is not conducted from the battery DB to a detecting and indicating circuit 1 whereby the transistor Q2 is not put ON and the light emitting diode D4 is not lighted. According to this method, it may be confirmed whether the storage battery B is connected to the charging circuit or not.

Title: Multi-function key input circuit
Inventor: ABE MASAYOSHI
IPC: G06F3/02
Filed: 1978-10-20
Abstract: PURPOSE: To realize a multi-function key input circuit, by which not only a fixed signal or corresponding signal but also another signal can be obtained making use of a difference in ON time of a key switch.  
     CONSTITUTION: When key signal A is held at level H with key switch SW ON, 1st following clock (ϕ) inverts output Q of FF2 into H to obtain signal Q 2 . This change inverts output Q of FF3 into H and inversion Q into L synchronizing with next clock (ϕ). As a result, the output of NAND5 is held at L when both its inputs are at "H". The key signal is therefore at L for the 1st one period of clock (ϕ) after a change into H. In addition, when SW stays ON continuously until the output of delay circuit 4 receiving signal Q 3  from FF3 changes in level to H lagging by time (t d ), inputs to AND6 both become H to obtain output C and H continues until SW turns OFF. In this way, functions can be changed by making use of a difference in operation time.
