This invention offers a data communication system that can perform data communication and detection of a data read-in request signal while reducing the number of communication lines to three, and is tolerant of noise. The data communication between a microcomputer and a key scan IC and the detection of the data read-in request signal are performed through a control line, a clock line and a data line. The data communication system is provided with a data line control circuit that controls the data line so that outputting of the data read-in signal RDRQ to the data line is disabled when first command data is inputted to the key scan IC through the data line, and that the outputting of the data read-in request signal RDRQ to the data line is enabled when second command data is inputted from the microcomputer to the key scan IC through the data line.

This invention offers an LCD drive circuit that prevents conversion to a wrong duty driving state and an unintended display caused by taking in of serial data corresponding to the wrong duty driving state. The LCD drive circuit is provided with an LCD drive signal generation circuit that generates driving signals to turn LCD segments on and off based on serial data received by a serial data receiving circuit and is switchable between a ¼ duty driving state and a ⅓ duty driving state. The LCD drive circuit is also provided with a driving state setting circuit that sets the LCD drive signal generation circuit to the ¼ duty driving state based on identification data when the serial data receiving circuit receives the serial data corresponding to the ¼ duty driving state and thereafter forbids the LCD drive signal generation circuit to take in serial data corresponding to the ⅓ duty driving state when the serial data receiving circuit receives the serial data corresponding to the ⅓ duty driving state.

In a starter, an output shaft is disposed on a same axial line with a motor shaft through a planetary gear reduction device. The output shaft has an accommodation recess at the rear end thereof and rotatably receives the top end of the motor shaft therein through a ball. The output shaft and the motor shaft have respective end surfaces opposing each other in the axial direction with a spacing therebetween under a condition that the ball is disposed between the output shaft and the motor shaft. A thrust receiving member thinner than the spacing is disposed in the spacing. The thrust receiving member limits a movement of the output shaft toward the motor due to wear of the accommodation recess.

A starter for an internal combustion engine includes a motor, a pinion gear connected to the motor to be engaged with a ring gear of the engine. The pinion gear has teeth of a negative addendum modification whose number is larger than a standard gear that has the same outside diameter. Therefore the gear ratio of the pinion gear to the ring gear can be increased without change of the outside diameter thereof.

A starter for an internal combustion engine is comprised of an armature, a motor case, a planetary gear speed reduction mechanism connected to an armature shaft, a frame and a partition plate disposed between the motor case and the frame. The partition plate has an armature-shaft hole and a chamber-connection passage between the armature shaft hole and the armature shaft for connecting the motor chamber and the speed reduction chamber. An undulating circumferential groove is formed between the partition plate and the frame to connect the speed reduction chamber and the outside. A long water drainpipe is removed from a starter for a recreational vehicle.
