IPC: F02D45/00
Filed: 1986-07-09
Abstract: PURPOSE:To relieve a transient sudden variation such as a torque shock, etc. by reading a control condition pattern corresponding to the change of an operating condition from a memory means when said change is detected, and controlling an engine according to this pattern. CONSTITUTION:A control unit 1 determines a control zone based on a negative pressure and an engine speed. And, when the change of zone is detected, a zone shifting type table 28 is read from a ROM 24, and the parameters of a pattern corresponding to the zone change is selected and read from a zone shifting pattern table 29 in order in accordance with a transient condition, to carry out an engine control according to the read parameters. Thereby, it is not necessary to prepare plural complex programs or to change a program, and shifting to the optimum zone can be carried out only by selecting one out of plural parameters which are previously prepared based on the change of the zone, relieving a transient sudden variation.

Title: Conveyor belt
Inventor: SUMINO SHINICHI
IPC: B65G15/08
Filed: 1980-11-17
Abstract: PURPOSE: To effcetually prevent the deterioration of the overlapped part of a cylindrical conveyor belt, by making the overlapped part lighter than the other part.  
     CONSTITUTION: Both the side edge parts 11a, 12a of a conveyor belt 14 are made of low-specific-gravity rubber such as sponge rubber and foamed urethane. Since the parts 11a, 12a are made of the low-specific-gravity rubber, the weight of the overlapped portion of the belt 14 made cylindrical is small and the bending moment acting to the side wall sections of the cylindrical belt is low and the partial bending moment acting to the overlapped portion is also low.
