Title: Production of high solid content active clay slurry
Inventor: SAEKI YOSHISATO
IPC: B01F3/12
Filed: 1979-01-19
Abstract: PURPOSE:To improve dispersibility of a high solid content active clay slurry by adding a latex base binder to an aqueous phase before dispersing active clay, singly or together with an inert clayey substance, in water. CONSTITUTION:Active clay is dispersed, singly or together with an inert clayey substance, in an aqueous solution added in advance with a latex base binder, to prepare a clay slurry. It is preferable to adjust the pH of the aqueous solution within the range of 9.0-11.0 before the active clay is dispersed therein.

Title: Neutral control method and device thereof
Inventor: ITO YOSHITERU
IPC: F16H59/54
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption and operation characteristic at running in traffic-snarl by changing a delay time according to a vehicle operating condition before beginning neutral control. SOLUTION: A vehicle operating condition memory means 1c takes in the throttle opening corresponding to an engine load from a throttle opening sensor 3 and the vehicle speed from a vehicle sensor 4, and when the vehicle speed exceeds the vehicle speed set value, a delay time setting means 1d judges not to be running in traffic-snarl to set a relatively short delay time, and when it does not exceed, the means judges to be running in traffic-snarl to set a relatively long delay time. This is because the vehicle generally runs in the creep condition in the case of running in traffic-snarl without opening the throttle. When the neutral control beginning condition is realized by a control beginning judging means 1b, the neutral control is carried out when the continued time of realization of the condition exceeds the delay time.
