Filed: 1985-05-07
Abstract: PURPOSE:To easily detect coordinates of a light intercepting object in a rectangular area, by arranging plural light emitting elements along the adjacent two sides of the area and reflection mirrors connected with photodetecting elements along the other two sides. CONSTITUTION:A rectangular area, in which the position of a light intercepting object F is detected, is provided and light emitting element rows LEDxa and LEDya, each of which is composed of numerous light emitting elements, are provided along the adjacent two sides O-B and O-D of the area. In addition, reflection mirrors Mx and My are respectively provided on the other adjacent two sides and, at the same time, the 1st and 2nd photodetecting elements PDy and PDx are respectively positioned to coordinates (b) and (d). Each light emitting element row is successively caused to light and, when a light intercepting object exists at the point of coordinates F, lights from the light emitting elements at positions (l) and (m) are intercepted by the object F and do not reach the photodetecting elements PDy and PDx. Therefore, when the light emitting elements, whose light do not reach the photodetecting elements, are known, the coordinates of the light intercepting object F can be found.

Title: Engine starting device
Inventor: SUGIYAMA TAKESHI
IPC: F02N15/04
Filed: 1990-04-11
Abstract: PURPOSE:To downsize and lighten a starter motor as well as to reduce noise by interposing paired non-circular gears in a starting drive train, and thereby positioning non-circular gears in such a way that change in angular velocity is caused in response to the fluctuation of the torque of a crank shaft. CONSTITUTION:An elliptic gear 11b is fitted onto the crank shaft 2 of an engine 1, and an elliptic gear 11a in a similar shape is also fitted onto the rotating shaft 12 of a ring gear 3, so that these paired elliptic gears 11a and 11b are meshed with each other in such a way that rotation can thereby be transferred. In this case, the elliptic gear 11b is fitted on so as to met the piston position of the engine 1 so that the position for change in angular velocity can be secured in response to the fluctuation of the torque of the engine 1. Accordingly, when the elliptic gear 11a at one side is adjusted in phase to meet the aforesaid piston position, fluctuation in torque to which the crank shaft 2 is subjected, is conditioned to be cancelled by change in angular velocity. As a result, no fluctuation in the torque of the engine 1 is transferred during the operation of a starter motor 13, the motor section is thereby operated roughly by constant current under a constant load.

Title: Digital time switch
Inventor: FUCHIGAMI HIROYUKI
IPC: H04Q11/04
Filed: 1987-04-22
Abstract: PURPOSE:To obtain a digital time switch to prevent a useless delaying by handling a calling path to use plural time slots and a calling path to use one time slot separately. CONSTITUTION:A digital time switch has two data memories 1A and 1B. Concerning the calling path to use plural time slots, the data of the time slot are alternately written with a switching circuit 4 to two data memories 1A and 1B and alternately read. Thus, at the calling path, the delaying for one frame occurs. On the other hand, concerning the calling path to use one time slot, the data of the time slot are written to two data memories 1A and 1B in the same way. Thus, even when the reading is alternately executed to two data memories, the delaying does not occur in the calling path in the same way that the writing and reading are essentially executed by using one data memory.
