Title: Digital radio relay method and adjustment of transmission power in digital radio relay method
Inventor: JIYUTSUKA HENRIKUSON
IPC: H01L27/00
Filed: 1990-11-14
Abstract: PURPOSE: To realize an interference-free receiving operation by increasing the transmission power temporarily to a level close to a maximum transmission power when the variation rate of receiving signal level or the rough estimate of error rate exceeds a predetermined threshold level. CONSTITUTION: Presence of a multipath state is observed by detecting the state of a signal Smp representative of an undue variation rate of signal level. When a multipath state is detected (Smp=1), state of a signal Serr representative of error state is observed at a point 22 and a decision is made whether an error state is present. In case of a state Serr=1, the multipath state and the error state are present simultaneously and a maximum transmission power Pmax is set at a point 23 and transmission processing is performed with that maximum power during a tie period T1 after final detection of simultaneous occurrence of the multipath state and the error state. The purpose for employing the maximum transmission power is to minimize the time when the error rate is higher than 10<-3> to 10<-6> at the time of receiving a signal.

Abstract: PURPOSE: To easily adjust the oscillating torque of a lens barrel. CONSTITUTION: Insertion holes 12L and 12R in which a coupling shaft 25 is inserted in a direction parallel with an optical axis C are respectively formed on the coupling parts 11L and 11R of left and right main bodies 10L and 10R. Then, a female screw 13R in which the male screw 25a of the coupling shaft 25 is screwed is formed in the insertion hole 12R of the right mirror body coupling part 11R. The coupling shaft 25 is inserted in the insertion hole of the coupling part and fixed in a state where the male screw 25a is thrust into the female screw 13R of the right mirror body coupling part so that frictional force equal to or above a fixed value may be generated between the objective lens side end face of the left mirror body coupling part and the ocular side end face of the right mirror body coupling part.  In the case the oscillating torque of a left mirror body to a right mirror body is lowered after shipping, an oscillating torque adjusting screw 1 previously thrust into the left mirror body coupling part is thrust further so that the frictional force being resistance against force that the left mirror body coupling part is going to oscillate may be generated between the coupling shaft 25 and the left mirror body coupling part.
