Title: Optical receiver
Inventor: TAJIMI NOBURO
IPC: H04B10/572
Filed: 1991-03-18
Abstract: PURPOSE:To control the multiplication factor of an ADP to the optimum state by detecting the value of a direct current flowing to the APD and feeding back the direct current so that the value can become that of the direct current which flows to the APD when the multiplication factor is the optimum. CONSTITUTION:When the light receiving power is small and a current-to-voltage converted voltage value is higher than the + terminal voltage of an operational amplifier 10, the bias voltage of an APD is controlled by supplying a high voltage from a high voltage generator 7 by means of a bias controlling transistor 11 by utilizing the voltage drop of a bias controlling resistance 6. Therefore, the APD current is controlled to a fixed value. When the light receiving power is large and the current-to-voltage converted voltage value is lower than the + terminal voltage of the amplifier 10, a diode 8 is conducted and the amplifier 10 is set to a fully fed back state and, as a result, the + terminal voltage is outputted irrespective of the APD current. Under such state, the APD is set to a self-control bias state by the resistance 6.

Title: Engine intake quantity controller
Inventor: OKAMURA MASAYUKI
IPC: F02M69/32
Filed: 1989-03-04
Abstract: PURPOSE:To prevent oil or a mixture of oil and carbon from sticking to the inner wall of an intake passage by making an opening diameter at the intake passage side of a PCV passage smaller than that at the intake passage side of a bypass passage opposed to the former. CONSTITUTION:At time of idling state, most of idle air flows through a bypass passage 126, so that the periphery of an opening 22 comes nearer to negative pressure by this idle air flow. Therefore blow-by gas taken in an intake passage 104 form a PCV passage 116 is blown to the opening 224. Since a PCV port 118 is made smaller than this opening 224 hereat, most of the blow-by gas is inhaled into the bypass passage 126 as it is without colliding with an inner wall of the intake passage 104. Consequently, the blow-by gas or the like will not flow back to the side of a throttle valve 132, thus oil or a mixture of oil and carbon is prevented from sticking to such a part as interfering with the opening or closing of the intake passage 194 and the throttle valve 132.

Title: Centrifugal automatic angle of lead device for internal-combustion engine
Inventor: ITOU KENICHI
IPC: F02P5/07
Filed: 1984-03-19
Abstract: PURPOSE:To reduce the cost of manufacture without either forming a long hole on a base plate or carrying out heat treatment as in the conventional method, by restraining the maximum angle of lead for ignition timing by determining the forms of an operating arm and an ignition timing plate, or by utilizing rotation torque by means of a return spring, in the direction of angle of lag for ignition timing, of said ignition timing plate. CONSTITUTION:When a base plate 2 is rotated counterclockwise due to the rotation of an engine, since the convexly circular face 17 of an operating arm 6 is engaged with the operating- arm engaging face 15 of an ignition timing plate 10, the timing plate 10 and a timing shaft 7 rotate in an integrated form with the base plate 2 in the same direction. Centrifugal weights 3 will not move until engine speed has reached approximately 600r.p.m., since the centrifugal force applied to the weights 3 is small. When 600r.p.m. is reached, since the engaging point C1 between the convexly circular face 17 and the operating-arm engaging face 15, is in a position far away from the rotary center A, the centrifugal weights 3 swing outwardly and clockwise centering around a shaft 4, and the convexly circular face 17 presses the engaging face 15 and, as a result, the timing plate 10 rotates counterclockwise to advance an angle. At an engine speed of 2,500r.p.m. or more, the timing plate 10 is returned to the angle of lag, and these operations are repeated.
