Abstract: PURPOSE:To prevent mis-connection and to reduce the time till talking connection by sending a subscriber key number read out of a storage circuit when a request comes from an exchange to be connected. CONSTITUTION:When a caller hooks off a HS (handset) 6 and dials a special number for telephone service from a PB (pushbutton) 1, an MSF (multi-frequency signal sending circuit) 2 converts the signal into a multi-frequency signal and sends the result to an exchange LS 4 via a CKT (telephone set circuit) 7.When the MFR (multi-frequency signal receiver circuit) 3 receives a subscriber key number sending request signal from the LS 4 via the CKT 7, a CTL (control circuit) 8 reads the subscriber key number stored in a storage circuit MEM 5 and transfers it to the MFS 2. The MFS 2 converts it into a multi-frequency signal and sends it to the LS 4. Thus, the operation of the caller is less and mis-connection is prevented. Moreover, the time till the communication connection is reduced.

Title: Vehicle speed controller for agricultural tractor or the like
Inventor: HASHIMOTO HIROSHI
IPC: B60K20/00
Filed: 1980-06-13
Abstract: PURPOSE: To automatically control a vehicle to a constant speed and simplify the structure of a  vehicle speed controller, by regulating the degree of engagement of a friction clutch, which acts to  perform stepless transmission control between the speed shift stages of a step transmission, so that  the output rotational frequency of the clutch is equal to a set level.   
     CONSTITUTION: The rotational frequency of a transmission shaft 5, to which the torque of a  transmission shaft 4 is applied through a friction clutch 6, is detected by a sensor 68. The output  signal of the sensor 68 is applied to a summing point 76 through an F-V converter 70. A signal  corresponding to an output rotational frequency level set in a control amplifier 75 and the signal  from the sensor 68 are compared with each other at the summing point 76 so that the difference  between the signals is determined. An electrical current of such polarity as to reduce the difference  is applied to a servomechanism to change applied oil pressure on the friction clutch 6 to alter the  degree of engagement of the clutch. The speed of a vehicle is thus controlled to a constant level.  The changing control is steplessly effected within the range of vehicle speed change ratio between  the speed shift stages of the step transmission of the tractor by altering the set rotational frequency  in the amplifier 75.
