Filed: 1989-07-13
Abstract: PURPOSE:To always receive a control signal correctly independently of timing even or a call name including a frame synchronizing signal in a call signal by providing two data reception means. CONSTITUTION:A connector 1 consists of a hybrid 2 connecting to an input terminal 7, a radio section 3, a control section 4, a 1st data reception means 5 connecting to the control section 4, and a 2nd data reception means 6. In such a case, the connection device 1 can receive a control signal from a time T1. When the same pattern as the frame synchronizing signal is included in the call signal, the frame synchronizing signal is detected in error at a time T2 and stored in a buffer with a prescribed bit length up to a time T3. On the other hand, the signal reception means 6 detects the frame synchronizing signal at a time T4 and stores it to a buffer of a prescribed bit length up to a time T6. Thus, the data reception means 5 applies reception analysis at the time T3 and judges it to be reception NG, the data reception means 6 applies reception analysis at the time T6 to receive a call signal from a portable telephone set correctly.

Title: Driving device for automatic tool exchange
Inventor: MURAKI SHINJI
IPC: B23Q3/157
Filed: 1984-08-31
Abstract: PURPOSE:To aim at simplification in the construction of a driving part as well as to aim at the promotion of speediness in tool change motion, by making rotation of a twin arm and its retratable motion, namely, combined motion securable with one driving source, while letting these combined motions perform so smoothly at the same time. CONSTITUTION:Rotational motion of a rotary actuator 27 as one driving source is converted into reciprocating motion of a twin-arm shaft 5, while the rotational motion of the side driving source is transmitted to the twin-arm shaft 5 as motion toward the rotation with an intermittent movement mechanism. Hereat, a slider 8 of a reciprocating slider crank mechanism and a Gneva gear of the intermittent movement mechanism both perform less shock and smooth motion so that tool change operation is performable at high speed under smooth movements. Since comes to receive transmission power only at a partial range to the driving source, the rotational motion and the retractable motion of the twin-arm shaft 5 are well combinable in an idear state. Therefore, a driving construction is simplifiable and, what is more, tool exchanging motion is made into being speedier than ever before.
