Title: Ditch conver
Inventor: ONISHI KUNIAKI
IPC: E03F5/04
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To prevent unnecessary coming-off of ditch cover from the opening part of a ditch even if the ditch cover is made lightweight by providing a locking part for being locked on the other adjacent ditch cover from the vertical direction on one side of a ditch cover direction. SOLUTION: A locking part 6 for being locked on the other adjacent ditch cover 4 from the vertical direction is provided on one side of the ditch width of a ditch cover 4. The locking part 6 is composed of rectangular plate-like small pieces, and mounted on the upper face of one side of the ditch longitudinal direction of the ditch cover 4. The locking part is projected from a side edge in the longitudinal direction of the ditch cover 4 outward in the longitudinal direction of the ditch, and the projection part is covered on the upper face of the other adjacent ditch cover 4 from upward. Thus, because the other adjacent ditch covers 4 are mutually locked by the locking part 6, even if large wind pressure acts on one ditch cover 4, the ditch cover 4 is pushed by the adjacent ditch cover 4 to prevent scattering of the ditch cover 4.  In addition, at the time of maintenance, only the ditch cover 4 is easily removed by lifting the other side of the ditch width direction of the ditch cover 4 and pulling it toward you.

Filed: 1992-06-15
Abstract: PURPOSE:To obtain a stable operation by adding and integrating an input reference voltage to a voltage value from a high frequency signal level voltage value generating means, sending out a gain control signal by which a high frequency decreases gradually and executing attenuation adjustment. CONSTITUTION:An attenuator 11 attenuates a high frequency signal S11, and a high frequency amplifier circuit 12 amplifies the high frequency signal S11, and also, outputs an amplified high frequency signal S12 to which automatic gain control by a closed loop is performed in accordance with its level. Subsequently, a detector 13 being a high frequency signal level voltage value generating means outputs a detection voltage VIN obtained by detecting the amplified high frequency signal S12. Moreover, an adding/integrating circuit 18 adds and integrates this detection voltage VIN and a reference voltage -VR from the outside, supplies them to the attenuator 11, and the automatic gain control corresponding to the level of the high frequency signal S11 by the closed loop is performed. In such a way, it does not occur that a high frequency of a frequency characteristic viewed from an input reference voltage extends unnecessarily, it becomes unnecessary to consider the frequency characteristic to the high frequency, and a stable operation is obtained.
