Title: Apparatus for judging molten and solidified state of resin in mold in injection molding machine
Inventor: KOBAYASHI YOJI
IPC: B29C45/76
Filed: 1989-06-28
Abstract: PURPOSE:To enhance the judging accuracy of the molten and solidified state of a resin by comparing the threshold value of the vibration damping factor of an ultrasonic wave obtained when the resin in a mold transfers from a molten state to a solidified state with the vibration damping factor after the mold is filled with the resin. CONSTITUTION:The vibration damping factor alphao (threshold value) in such a case that a resin transfers from a molten state to a solidified state is experimentally determined corresponding to the kind of a resin. Next, the data of the kind of a resin to be used is inputted to a console 8 and, based on this data, the threshold value alphao corresponding to the resin to be used stored in the ROM of a calculation apparatus 7 is read on an RAM. Subsequently, molds 1, 2 are filled with the resin based on the output signal from a main control apparatus 10. When the filling with the resin is completed, the distance between an ultrasonic transmitter 5 and an ultrasonic receiver 6 stored in the ROM of the apparatus 7 is read on the RAM and the vibration of an ultrasonic wave in the transmitter 5 and the receiver 6 is measured and, on the basis of this value, a vibration damping factor alpha is calculated. When alpha>=alphao is judged, it is displayed that the resin is in a solidified state on a display apparatus 9.

Title: Control device of fuel injection quantity in internal-combustion engine
Inventor: URUSHIYA MASAHIRO
IPC: F02D41/10
Filed: 1984-08-06
Abstract: PURPOSE:To control air-fuel ratio at transient time to a fixed value and prevent emission from worsening, by providing an intake air quantity detector and an intake air quantity weak value arithmetic means and using a weak value at acceleration time while a detected intake air quantity at non-acceleration time so as to calculate an injection quantity of fuel. CONSTITUTION:An intake air quantity weak value arithmetic means, to which a signal Q of an intake air quantity detecting means is input, calculates a weak value Qi to be input to a fuel injection quantity arithmetic means. If an accelerative condition decision means detects an accelerative condition, the fuel injection quantity arithmetic means calculates an injection quantity from the intake air quantity weak value Qi and a rotary speed N. While the fuel injection quantity arithmetic means, if non-accelerative condition is detected, calculates the injection quantity from the detected intake air quantity value Q and the rotary speed N. In this way, the injection quantity of fuel, being not increased rapidly more than necessary, enables air-fuel ratio to be prevented from becoming a rich state because the injection quantity is calculated by using the weak value at acceleration time.
