Title: Antenna protection system against strong wind
Inventor: MIYAUCHI TAKASHI
IPC: H01Q3/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To automatically make an antenna face a zenith in strong wind so as to prevent the antenna from being destroyed. SOLUTION: When a state, in which wind speed is not less than a reference wind speed VAL continues for reference continuing time TOV, a wind speed recorder 3 emits an alarm(ALM) signal to ACU 4. ACU 4 responds to the alarm signal ALM, stops the operation of an antenna 5, measures/stores the operation elevation angle of the antenna at that time and saves the antenna 5 by making it face a zenith. When a state in which the wind speed is below a reference speed VAL continues only for a reference continuation time TDN, the wind speed recorder 3 stops the alarm signal ALM. When the alarm signal ALM stops, ACU 4 restores the antenna 5 to the stored operation elevation angle.

Title: Pipeline control system
Inventor: AIZAWA RYOICHI
IPC: G06F15/16
Filed: 1986-04-14
Abstract: PURPOSE:To confirm that a desired pipeline is constituted by providing a connecting means and a connection confirming means in each module. CONSTITUTION:Input and output buses R, W are designated to a desired module M. Before starting pipeline processing, if its own module is in the ready state and designated input bus D is active, operation of outputting an active signal to the designated output bus is successively executed from the leading module M, and desired modules M are connected in a chain. The connecting operation is inverted when arrived at the final module M and switched to forming operation that outputs a connection confirming signal to the output bus D. Each module M receives the connection confirming signal from the designated output bus D, and sends back the connection confirming signal to the designated input bus D, and executes this connection confirming operation in a chain. Establishment of desired pipeline is confirmed by the fact that the connection confirming signal is outputted from the leading module M, and pipeline processing is started.
