Title: False bell sound control device in facsimile or the like
Inventor: ONISHI TORU
IPC: H04M11/00
Filed: 1989-04-13
Abstract: PURPOSE:To offer a ringing tone free from a sense of inconguity by storing previously the pattern of a calling bell sound at the time of incoming from an exchange, and ringing the false bell sound corresponding to the pattern. CONSTITUTION:When a calling bell signal arises, the pattern of this bell signal is stored in a RAM 5. A pattern signal to be stored is data to show the feature of the received calling bell sound such as, for instance, a sounding period and a silent period or the shape of envelope, etc. The false bell sound is determined by controlling the oscillation circuit of audible frequency installed at a bell sound control part 9 or gating the output of the oscillation circuit according to this data. Thus, the calling bell sound of an exporting destination can be dealt with even if it varies variously, and besides, a case where the original calling bell sound is used in an extension exchange can be dealt with as well.

Title: Electronic circuit
Inventor: KAWASAKI TETSUYA
IPC: H03K19/0175
Filed: 1992-04-13
Abstract: PURPOSE:To externally attain initial setting by holding a bi-directional external buffer to the input state for a prescribed period after the transition from an active period of an initializing signal to an inactive period and setting the buffer to the output state to eliminate the addition of any external terminal. CONSTITUTION:An initializing signal (regarded to be initialized at an L level) is delayed by a time DELTAt at a delay circuit 1. While an output of the circuit 1 is at an L level, the state of the bi-directional external buffer 3 is controlled by an output from the circuit 1. That is, while an output of the circuit 1 is at an L level, the buffer 3 is set to the input state and when the output of the circuit 1 is at an H level, the buffer 3 is set to the output state. Then the buffer 3 is switched from the input state into the output state being delayed by DELTAt time after the level of the initializing signal changes from an L to an H level. Since an output from the buffer 3 is latched in an FF 4 by a leading edge of the initializing signal, the initial setting data set externally when the buffer 3 is set to the input state are surely fetched when the time DELTAt is set to be a sufficient time.
