Title: High load transmission belt
Inventor: TSUJI SHOJI
IPC: F16G5/16
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To reduce the pitch noise, and to make the constant oil supply unnecessary, by forming an endless carrier by alternately stacking the resin bands and the metallic bands to form a layered body, and positioning the resin bands as the uppermost layer and the lowermost layer. SOLUTION: An endless carrier 2 is formed by alternately stacking the resin bands 2a and the metallic bands 2b, in such manner that the uppermost layer 4 and the lowermost layer 5 are formed by the resin bands 2a. By forming the uppermost layer 4 and the lowermost layer 5 to be kept into contact with a block 3, with the resin bands 2a, the constant oil supply for the lubrication, becomes unnecessary even in a push transmission type belt which is driven by the sliding of the metallic block 3 on the endless carrier 2, so that the belt driving device almost free from the maintenance, can be provided. Further by compensating the tensile strength of the resin bands 2a which is sometimes insufficient, with the metallic band 2b installed between the resin bands, the endless carrier 2 having the sufficient tensile strength can be obtained.

IPC: H04M11/00
Filed: 1989-10-31
Abstract: PURPOSE:To identify kinds of outgoing telegraphic message from a center independently of the length of a telegraphic message or the specification of a terminal equipment by checking a header part of an inputted outgoing text sequentially and identifying the kind of the outgoing telegraphic message. CONSTITUTION:A CPU 702 of a main control section 605 in a terminal use network controller (T-NCU) 6 uses a MODEM 613 demodulate and fetch an outgoing telegraphic message sent from a center side network controller 2 and operates a timer counter 701 when the presence of a mark M in the header part of the fetched outgoing telegraphic message is decided. Then the CPU 702 identifies it to be a decoded telegraphic message when a space S in succession to the mark M before the timer counter 701 expires, and when no space S comes in succession to the mark M even when the timer counter 701 expires, the CPU discriminates the telegraphic message to be a through-text. Thus, the kind of the outgoing telegraphic message from the center is identified independently of the length of the telegraphic message and the specification of the terminal equipment.
