摘要:
A controller of injection molding machine capable of stabilizing a peak pressure of resin appearing when an injection process is switched to a pressure-holding process, by reducing the variation of the peak pressure. Resin pressure Pr is detected at every predetermined sampling period Δt. There is a time lag between the time at which the resin pressure reaches an injection/pressure-holding switch determining resin pressure P(v−p) and the sampling time t2 at which the resin pressure that has reached the value P(v−P) is detected. Hence, a difference Ve between the detected resin pressure value Pr′ and the switch determining resin pressure P(v−p) is obtained. The transition time period T in which pressure should be changed from a pressure-holding start pressure Ps to a pressure-holding pressure Pp is corrected by T=T0−α×Ve to make the transition time period T shorter when the difference Ve is greater, to thereby hold down the peak pressure Pmax. By this, the variation ΔPmax of the peak pressure Pmax is reduced. Since the pressure is kept uniform, the quality of a molded produce improves.

摘要:
A computer solves an item-based one-dimensional sub-optimization problem independently of the other items. For the item-based solution found, the computer determines whether machine interference between the items is eliminated and whether a work-in-process inventory is sufficient. If machine interference is not eliminated or the work-in-process inventory is not insufficient, then the computer updates a corresponding Lagrange multiplier and reexecutes the solving of the problem.

摘要:
A delay time stabilization circuit is used in a timing generator which provides a reference timing of a semiconductor IC test system. The delay time stabilization circuit includes a delay control circuit, a period generator which generates period signals necessary for DUT (device under test) testing, a loop forming switch, and a period counter 31 for counting the period in a loop circuit. The calibration process starts by setting the loop forming switch. A start pulse generation circuit generates n pulses when receiving one trigger pulse which pass through a CMOS variable delay circuit and the loop circuit to a 1/n divider circuit. The n pulses are divided by n to produce a signal pulse which triggers the start pulse generation circuit. In the DUT testing, the period generator 11 generates the period signal necessary for the testing which is the same repetition rate as generated by the start pulse generation circuit, resulting in the same power dissipation in the calibration process and the DUT testing.

摘要:
When a liquid chlorosilane compound inadvertently runs out of a container, the liquid must be disposed by absorbing using an absorbent since chlorosilane compounds are generally very dangerous and toxic. Instead of dry sand conventionally used as an absorbent in such a purpose, the invention purposes that a very efficient effect of absorption can be obtained by using a silica-, silica/alumina-based porous ceramic material or a mixture of them as an absorbent without gas evolution in the liquid and with little temperature increase of the liquid when the absorbent material has a specified content of silica or silica/alumina and a pore diameter distribution.
