Abstract:
The present invention is directed to a convenient and economical method for improving the rate of raising newborn piglets from the pregnancy of the sow to the weaning of the piglets. The method reduces the incidence of premature piglets and increases the lacteal yield of breeding sows by feeding the breeding sows a feed containing saccharides mainly composed of oligosaccharides.
Abstract:
This invention relates to a process for preparing bisphenol A of good heat stability by heat-treating bisphenol A containing a very small amount of impurities in a molten state at 185.degree. to 220.degree. C. for 5 to 60 minutes in an oxygen-free atmosphere and the process yields bisphenol A of good heat stability which shows reduced coloration when heated. Bisphenol A prepared by this process has excellent properties relating to color and is particularly suitable as raw material for the manufacture of polycarbonates where the requirement for color is strict.
Abstract:
An injection apparatus of a plunger type for injecting reinforced materials such as BMC is of a single barrel type or a double barrel type having a rotatable plunger disposed in the barrel. A check valve device for preventing a back flow of the materials in a metering process is provided such that it is closed when the plunger is actuated to move axially for injection.

Abstract:
A method is provided for estimating a temperature distribution history in the case of line-heating flat-plate steel by high frequency induction. The method of estimating the temperature distribution history includes a first step of measuring a history of temperature distribution that is generated when a test piece of sheet steel is spot-heated; a second step of analyzing an induction current distribution that is generated when the sheet steel is spot-heated; a third step of expressing the induction current distribution by an approximation equation of the initial induction current distribution at an initial temperature and temperature dependent correction factor of the initial induction current distribution, and identifying the initial induction current distribution and the temperature dependent correction factors based on the temperature distribution history and the induction current distribution; a fourth step of analyzing internal heat generation from the initial induction current distribution, the temperature dependent correction factor, and a temperature dependency of electrical resistivity of the sheet steel; and a fifth step of analyzing the temperature distribution history generated during the line heating by applying the internal heat generation to the sheet steel while the internal heat generation is being moved. According to the method, the temperature distribution history in the case where the flat-plate steel is line-heated by high frequency induction can be efficiently estimated at high precision.
Abstract:
The data reception apparatus includes a main processing unit that waits in a standby state so as to be able to receive the connection signal that is transmitted in a first communication mode, and further receives, after reception of the connection signal, the data signal that is transmitted in a second communication mode that is different from the first communication mode; a sub processing unit that is provided in addition to the main processing unit, the sub processing unit being capable of receiving the data signal that is transmitted in the second communication mode; a notification unit that is capable of notifying information to a user; and a notification control unit that controls the notification unit so that the notification unit notifies a communication error to the user if the sub processing unit has received the data signal although the main processing unit has not received the connection signal.
Abstract:
A data transmitting apparatus for transmitting data to a communication recipient by one-way communication includes a data transmitting unit transmitting data to the communication recipient by the one-way communication of a predetermined communication format; a data selecting unit allowing a user to select the data to be transmitted by the one-way communication; an instruction inputting unit allowing the user to input an instruction to transmit the data selected by the data selecting unit to the communication recipient by the one-way communication; a control unit controlling the data transmitting unit to transmit the data selected by the data selecting unit to the communication recipient by the one-way communication on the basis of the instruction input through the instruction inputting unit.
Abstract:
