IPC: G01V8/20
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To make between projectors and light receivers wireless by shift- driving plural projector elements, based on the projection signal of the projector element on the same axis and shift-driving each of the light-receiving elements based on the receiving signal of the light-receiving element on that optical axis. SOLUTION: In each of the projector elements D1 to Dn and D0 , a drive current is supplied from projector circuits 1a and 1b, light beams are emitted toward each of the light-receiving elements R1 to Rn and R0 side respectively. The projector circuits 1a and 1b operates by receiving a clock signal from a scan signal generating circuit 3, and shift-drives each of the projector elements D1 to Dn and D0 at each prescribed time, by a projector side shift circuit 4 using the projection signal of the projector element D which is the optical axis of the final stage as a start signal.  The light-receiving circuits 2a and 2b shift- drive each of the light-receiving elements R1 to Rn and R0 at each prescribed time, making them correspond to the driving of each of the projector elements D1 to Dn and D0 by the light-receiving side shift circuit 7 using the light- receiving signal of the light-receiving element R0 being the optical axis of the final stage, that is, while keeping the synchronized state.

Filed: 1987-11-26
Abstract: PURPOSE: To prevent a speed reduction device and a motor from being damaged due to an excessive loading by providing a slip mechanism which slips by an excessive loading and shuts off a rotation transmission in the rotation transmission path of the reduction device. CONSTITUTION: At the same time with a power connection to a motor 2, power is connected to an electromagnetic coil 8 as well, and by connecting a clutch mechanism 17, the rotate-driving force of the motor 2 is transmitted to a gear 6c. At this time, a gear 6e which is engaged with the gear 6c, and a gear 6f which is integrated by a frictional force by a belleville spring 27, are integrally rotated, and the rotation force is transmitted from the gear 6c to a gear 6b through the gears 6e, 6f, and rotate-drives a driving shaft 4.  When a user sits on a toilet seat 1, or the toilet seat 1 is manually turned in the opposite direction while the toilet seat 1 is electrically driven, the rotating force of the driving shaft 4 works as an excessive loading, and when the rotating force applied to the belleville spring 27 exceeds the frictional force between the belleville spring 27 and the gears 6e, 6f, the belleville spring 27 slips, and the gear 6e idly rotates, and the speed reduction device 3 and the motor 2 are prevented from being damaged due to the excessive loading.

Filed: 1987-11-25
Abstract: PURPOSE: To accomplish electrification by a low electric capacity by connecting one end of an expansible body fixed to a tank main body via the other end to a drain mechanism and a water supplying mechanism through a valve controlled by a switch unit in an operation mechanism structure. CONSTITUTION: When a switch unit 55 in an operation mechanism 5 is operated, a valve 54 is opened for a fixed time, and a fixed amount of cleaning water W flows from a water supplying mechanism 2 into an expansible body 51 with one end fixed to a tank part 11 in a tank main body 1, through an inlet pipe 52. Inflow of this cleaning water W increases an internal pressure of a tubular body 51a because the thickness of an outlet pipe 53 is thinner than that of the inlet pipe 52, so that the tubular body 51a is deformed so as to be expanded in diameter and to be shrunk in length for a fixed time, and a connection member 4 is pulled so as to open a valve for a drain mechanism 2 for a fixed time. In this way, electrification by a low electric capacity can be accomplished, and a drain amount can be standardized.
