There is disclosed a power door lock system for use with an automobile, The lock system comprises an actuator for locking or unlocking a door or the tailgate, a microcomputer, a key code transmitter mounted on the vehicle, a key code receiver connected with the microcomputer, a nonvolatile memory in which a key code is stored, timers connected with the microcomputer, a passenger-detecting circuit, and a switch that is closed when the door is completely closed. The microcomputer includes a comparator for comparing the key code detected by the key code receiver with the key code stored in the memory. The operation of the actuator is controlled by the microcomputer to prevent malfunction.

A microprocessor-based telephone set includes a telephone number memory, a number indicator, an abbreviated number scanning switch and associated control circuit, in addition to a push-button dial and a hook switch as equipped in the usual telephone set. Telephone numbers are preset in correspondence to abbreviated numbers, so that a telephone number is dialed automatically by simply specifying a corresponding abbreviated number using the scanning switch and indicator. By provision of an FM transceiver within the handset and a separate relay unit for establishing radio communication with the base telephone station, a mobile telephone system is configured.

Telephone equipment for reduced key operations

The present invention relates to a land mobile telephone system with enhanced operability realizing both the loud-speech and closed-speech operations by the single handset. The handset is installed detachably in a pad of a steering wheel of an automobile and having a power terminal for feeding electric power from an automobile-equipped battery to said handset devices when said handset is seated in the steering wheel pad, said controller having a speed mode selector which selects a loud-speech mode when said handset is seated in the steering wheel pad or selects a closed-speech mode when said handset is taken out of the steering wheel pad.

A sewing machine is provided which automatically drives an embroidery frame in two directions of X- and Y-axes during the time a sewing needle is disengaged from a cloth to be worked. An X-axis drive system and a Y-axis drive system are provided which drive the embroidery frame in the directions of the X- and Y-axes in a conventional manner. The machine includes an electromagnetic clutch mechanism which selectively engages or disengages a needle bar with or from a needle bar drive system in order to permit an increased stroke selectively for which the embroidery frame is driven for each stitch. Additionally, an electronic control system is provided which energizes the electromagnetic clutch mechanism to disengage the needle bar from the needle bar drive system whenever either one of X-axis and Y-axis components of the stroke contained in an embroidery sewing data exceeds a given value, and which deenergizes the clutch mechanism after the termination of driving the embroidery frame and engages the needle bar with the needle bar drive system. If either component of the stroke exceeds the given value, the arm shaft idles to maintain the needle bar at its upper dead center during the time the embroidery frame is being driven. Subsequently, when the drive to the embroidery frame is terminated, a downward movement of the needle bar is allowed.

Automatic embroidery sewing machine

An embroidery sewing machine is provided for automatically driving an embroidery frame along X and Y axes. The bed of the machine is provided with a pair of parallel slots extending parallel to the X axis. A pair of carriages extend through said slots and the opposite ends of a single Y-axis guide rod which extends parallel to the Y-axis are secured to said carriages. A traveller is movably guided along the guide rod and one of said carriages is movably guided along a similar X-axis guide rod mounted below the bed. A pair of servo motors each having a drive roller are disposed under the bed and the carriages and traveller are each provided with a plurality of rollers. Wires extend around the rollers and rotation of one of the servo motors drives the carriages upon which the Y-axis guide rod is mounted along the X-axis guide rod. The rotation of the other servo motor causes the traveller to be driven in the Y-axis direction along the Y-axis guide rod. The embroidery frame is magnetically secured to the traveller for easy detachment. The servo motors operate under the control of a magnetic tape.
