Title: Forced commutation device for thyristor
Inventor: NARITA HIROSHI
IPC: H02M1/06
Filed: 1980-03-21
Abstract: PURPOSE:To minimize the capacity of a commutation SCR and reduce a commutation loss at time of commutation by dividing a commutation condenser into plural condensers, connecting them in parallel and connecting in series control elements which delay the timing of starting an electric discharge on one condenser. CONSTITUTION:A commutation condenser is divided into two condensers such as C01, C02 and these condensers are connected in parallel. In addition, in series with one condenser C02 of these commutation condensers, control elements, e.g. saturable reactor SAL, which delay the timing of starting an electric discharge are connected. Thus on account of the restraining of an oscillation current peak value at time commutation, it is possible to use an element of small capacity as a commutation SCR and also to reduce a commutation loss at time of commutation. Consequently, the efficiency of a chopper, an inverter, etc. can be enhanced.

Filed: 1979-03-28
Abstract: PURPOSE: To enable adjustment of cooling time depending on the material width and reduce the facility costs, in the cooling bed in a bar steel rolling facility, by providing a mechanism to make the transfer pitch of walking beam variable.  
     CONSTITUTION: When transferringa material 4 on a movable rake 6, a drive line shaft 13 has eccentric cams 23, 14, and the rotation of the eccentric cam 14 causes a lever 17 to turn about a pin 18, so that the movable rake 6 makes a horizontal motion l. Due to the rotation of the eccentric cam 23, levers 7, 8 provide a vertical motion (lift, h) of the rake 6. Suppose the amount of eccentricity of the eccentric cam 14 as RA, the overall length of the lever 17 as L 1 , and the distance between fulcrum pins 18 to 16 as L 2 , it follows that l=L 1 /L 2 .RA. Therefore, in order to change the transfer pitch l, the distance L 2  between pins 18 to 16 should be changed by turning the screw shaft 20. Thus, it is possible to adjust the cooling time depending on the width of material 4, so that the length of cooling bed may be shortened, and that the facility cost may be reduced.
