Title: Mold stock for molding plastic
Inventor: KODAMA TAKASHI
IPC: B29C33/10
Filed: 1994-08-23
Abstract: PURPOSE: To maintain venting performance without causing clogging over a long period of time by a method wherein the mold stock consists of porous metal plate having a large number of small holes, which check resin from passing through and allow air or the like to pass, thereon and metal reinforcing block, which is made into an integral body with the porous metal plate.

At this time, since the porous metal plate 2 is formed into thin plate, the distance, over which air or the like passes, is remarkably shortened. Accordingly, the air in the cavity or the like is smoothly discharged through the small holes 2a of the porous metal plate 2 and the straight vent hole 3a of the metal reinforcing block 3. Thus, venting performance, which is stable over a long period of time without causing clogging, can be maintained.

Title: Air-fuel ratio controller for internal-combustion engine
Inventor: NAGAI TOSHINARI
IPC: F02D41/00
Filed: 1985-09-10
Abstract: PURPOSE:To carry out the learning control sufficiently when the density of air varied, by suppressing the learning control for the deflection quantity due to a double air-fuel ratio sensor system. CONSTITUTION:Learning control is executed only when the deflection quantity DELTAFAF of the average value FAFAV of the air-fuel ratio correction quantity FAF from a prescribed value 1.0 is larger than a prescribed value alpha. For example, the deflection quantity DELTAFAF of the average value FAFAV of the air-fuel ratio correction quantity FAF due to the distribution of the output characteristics of an O2 sensor and the variation through time or years of the parts such as fuel injection valve from 1.0 is + or -3% at most. The deflection quantity DELTAFAF in case of the traveling on a highland is + or -5% or so. Therefore, when the prescribed quantity alpha is set at 3%, learning control is not executed for the deflection quantity due to a double air-fuel ratio sensor system, and the possibility of control for the learned value FGHAC to be controlled to the upper limit value or the lower limit value reduces. Therefore, the variation of the air density can be sufficiently compensated.
