Title: Method for adjusting sensitivity of light receiving element of optical type touch panel
Inventor: TSUKAGOSHI TOJI
IPC: G06F3/0488
Filed: 1989-03-16
Abstract: PURPOSE:To surely detect a light shielding object by adjusting light receiving sensitivity so that the level difference of light receiving output signals in the light non-emitting time and light emitting time of a light emitting element can approach a prescribed value by switching a load on a light receiving element. CONSTITUTION:The levels of the light receiving output signals of the light receiving element 12a in the light non-emitting time and light emitting time of the light emitting element 11a are compared by sweeping and driving all the unit optical systems according to a check program assembled in a CPU 23. And the load resistance value of the light receiving element 12a is increased and the light receiving sensitivity is increased for the unit optical system in which no level difference between the above levels arrives at the prescribed value by switching the load resistance block 20 of the unit optical system 10 including an element whose performance is lowered to a resistor having a high resistance value. Also, when excessive disturbance light exists, the light receiving sensitivity is lowered by reducing the load resistance value of the light receiving element 12a. Thereby it is possible to omit complicated work and time required for a checking operation, and also, to use a device even at a place where the excessive disturbance light exists, and to always and accurately perform the detection of the light shielding object.

Filed: 1988-03-15
Abstract: PURPOSE:To reduce the load supported by the rear wheels and improve the running performance by directly driving the rear power shaft and the differential casing for the front differential shaft through a couple of gear engaging with them. CONSTITUTION:The driving power from the engine is transmitted through the pulley 55 for the power input shaft 54 to the transmission 5 where the speed is changed, and the power is propagated from the transmission shaft 57 through the rear power output shaft 52 to the front differential shaft 51 which is engaged through gear 60a, 60b with the shaft 52, whereby the body of the transplanter runs. Since the front differential shaft 51 is interlocked through gears with the rear power output shaft 52, the heavy rear power output shaft 52 provided with the side clutch and side brake mechanism can be arranged before the transmission 5. Thus, the weight balance of the transplanter body is improved to reduce the weight or load supported by the rear wheel to increase the running performance in the rice paddy fields. At the same time, the shaft number in the transmission 5 can be reduced whereby the transplanter can be miniaturized.
