Filed: 1989-02-16
Abstract: PURPOSE:To change the conference called participants at the reservation of conference and after the reservation and to open a telephone conference even though the reserved conference participants are different from the present conference participants by changing the conference called participants after inputting the telephone subscriber numbers, the identification numbers received at subscription to the telephone conference service, and the subscriber numbers equal to the conference called participants via a terminal and therefore attaining the change of the called participants. CONSTITUTION:When a subscriber 1 of the conference service reserves for a conference, the subscriber 1 inputs his own subscriber number and identification number as well as the number of a subscriber 3. In the case the subscriber 1 does not enter for the conference service, the subscriber number and the identification number of a subscriber 2 and the number of the subscriber 3 are inputted. As a result, the subscriber 3 is called back by a telephone conference equipment ACFE 7 on a reserved data and time after the reservation of the conference is through. Then the subscriber 3 serving as a conference caller inputs a conference start instruction via a terminal after the answers are received from the subscriber 3 and a conference participant 4. Thus a telephone conference is opened. Therefore it is not required to use the same terminal for reservation and opening of the conference nor to stick to a designated place for the conference.

Title: Production of light-color petroleum resin
Inventor: ENDO KAZUYOSHI
IPC: C08F240/00
Filed: 1985-02-27
Abstract: PURPOSE:To obtain a light-color petroleum resin by copolymerizing a specified fraction from petroleum thermal cracking, containing aromatic and aliphatic hydrocarbon compounds at a low temperature in the presence of a catalyst. CONSTITUTION:A fraction (a) having a b.p. of 150-200 deg.C and contained aromatic unsaturated hydrocarbon compounds, obtained in the production of ethylene and propylene by the thermal cracking of petroleum is mixed with 5-50% fraction having a b.p. of 15-70 deg.C and containing aliphatic unsaturated hydrocarbon compounds, obtained from the same thermal cracking. The obtained mixture is copolymerized at a low temperature of 0--30 deg.C in the presence of a Friedel- Crafts catalyst to obtain the purpose resin. The polymerization temperature is specified at 0--30 deg.C for the following reasons. When it is below -30 deg.C, the degree of polymerization of the resin is too high, so that its compatibility with oils or resins is decreased. When it is above 0 deg.C, the degree of polymerization of the resin is low enough to show improved compatibility but its scope of application is limited because the hue of the resin approaches that of the conventional resin.
