Title: Production of copolyester resin
Inventor: SUYAMA SHUJI
IPC: C08G63/183
Filed: 1994-01-20
Abstract: PURPOSE:To obtain a copolyester resin capable of undergoing a thermal free- radical decomposition by condensing a terephthalic acid compd. with a dihydric alcohol component contg. a specified amt. of a specific dihydric alcohol. CONSTITUTION:A copolyester resin having a number-average mol.wt. of 10,000-200,000 is produced by condensing a terephthalic acid compd. (e.g. terephthalic acid or dimethyl terephthalate) with a dihydric alcohol component contg. at least 1mol% dihydric alcohol of the formula (wherein R1 and R2 are each methyl or ethyl). Examples of an alcohol which can be used together with the alcohol of the formula are ethylene glycol and propylene glycol. The use of the alcohol of the formula in an amt. of 1mol% or higher improves the effects of molecular cleavage by heating. The copolyester resin forms free radicals when heated, enabling a decrease in melt viscosity and an improvement in moldability.

Title: Melt indexer
Inventor: IMAYAMA TOKINORI
IPC: G01N11/06
Filed: 1981-02-13
Abstract: PURPOSE:To perform a reliable measurement of viscosity, by a method wherein, in order to measure a time during which a sample-extruding piston moves for a given distance, a light intercepting shutter, operating in a synchronizing manner via a lever, and a moving collecting element are mounted to regulate an intercepting distance. CONSTITUTION:If a sample-extruding piston 1 extrudes a sample and is lowered, a lever 2 turns centering around an axel 3, and a stopper 4 mates with a lever 5. Then, the lever 2 and lever 5 are monolithically united to work as a lever centering around a shaft 3 acting as a fulcrum, and a shutter 6 is pushed upward togetherwith the lever 5 and reaches a front surface of a collecting element 7 to intercept light. If the piston 7 is further lowered, the shutter stops intercepting the collecting element 7, and the time is measured to measure the viscosity of a sample. The collecting element 7 can move along a rail 11 by a feed screw to permit the regulation of the light-intercepting distance of the shutter 6. This facilitates the adjustment of a piston and produces a melt indexer which is less influenced by vibration.

Abstract: PURPOSE:To enable setting of the generation of sounds according to the liking of a user by counting sequentially time data of different kind set on the basis of an alarm time and by generating different sounds sequentially every time when counting of each time is ended. CONSTITUTION:When a time counted by a counter 4 coincides with the alarm time set in a counter 5, an output is generated from a coincidence circuit 6 and it triggers FF31, maintaining the input of a gate circuit 64 at ''1''. The output Q of FF31 turns ''1'' and is supplied to a sound controlling circuit 24, and a modulated-frequency signal makes a weak sound generated from a speaker 26 through the intermediary of a sound generating circuit 25. When a time passes and a counter 17 shows the same value with a time set in a latch circuit 15, an output ''1'' is generated in a coincidence circuit 18, the output of the gate circuit 64 is inversed, FF32 is triggered, the output Q turns ''1'', and the level of the terminal L2 of the sound controlling circuit 24 turns ''1''. Then, a high sound- level generating circuit is selected by the sound controlling circuit 24 and the sound from the speaker 26 is made high. And, when the output of a counter 19 coincides with the output of a latch circuit 16, the generation of the sound is stopped.
