摘要:
A polyamide composition comprises (a) 50 to 99 wt. % of a polyamide; and (b) 50 to 1 wt. % of a modified polyolefin which is modified with 0.001 to 10 mole % of an adduct component selected from alicyclic carboxylic acids or functional derivatives thereof which has a cis-form double bond in the ring, which can be substituted with a nonmodified polyolefin at a ratio of 1 to 90 wt. parts per 100 wt. parts of said modified polyolefin.

A resin composition comprising polyarylene sulfide, polyvinylidene fluoride and optionally ultrafine particles and a method of adhering a polyarylene sulfide article and a polyvinylidene fluoride article by using a resin composition comprising polyarylene sulfide, polyvinylidene fluoride and optionally ultrafine particles as an adhesive comprises the steps of melting portions of the polyarylene sulfide article and the polyvinylidene fluoride article to be adhered and the adhesive at a temperature between a melting point of the polyarylene sulfide and 400.degree. C.; bringing the portions to be adhered into contact with each other via the adhesive in a molten state; and cooling the adhered portions in a contact state.

An information processing apparatus includes a communicating section that executes communication with a server, a local storage section that stores subsequent data acquired from the server, and a data processing section that executes an acquisition process of the subsequent data, and a data playback process using data stored on a disc and the subsequent data stored on the local storage section. The data processing section builds a virtual file system for reading data stored on the disc and the local storage section, at the time of the data playback process, and performs the acquisition process of the subsequent data by transmitting a package ID to the server at the time of the acquisition process of the subsequent data, the package ID being information specifying a package corresponding to a file set necessary for building or updating the virtual file system.
摘要:
A digital PID process control apparatus is proposed wherein dynamic characteristics of the process are identified by supplying a persistently exciting signal to a closed-loop control system, and the persistently exciting signal is not supplied to the system after identification is completed, thereby tuning PID control parameters in accordance with the identified pulse transfer function. The control apparatus has a detector for detecting model error of the process in operation, a pulse generator for superposing a pulse signal on a set-point signal to the process when the model error is detected, a calculator for detecting a transient change in the model error when the input signal to the process changes in a pulse form, and a restart circuit for restarting generation of the persistently exciting signal when a change in the model error is detected, and for restarting an identification/tuning function.

摘要:
The process control apparatus according to the present invention is adapted to control the process automatically in compliance with the state of the process characteristics. In the process control apparatus, when the process characteristics are found to be in a steady state, the control is performed by a first process control operational means suited for sample controlling the process according to the control constants for the first process control operational means as determined during the control of a second process control operational means, while, when the process characteristics vary frequently, the control is performed by the second process control operational means which is suited from sample controlling the process.
