Title: Electronic interpreter
Inventor: MORIMOTO MASAFUMI
IPC: G06F17/28
Filed: 1980-04-15
Abstract: PURPOSE: To translate languages surely, by lighting a pertinent indication symbol simultaneously with outputting of the translation result to report that the sentence of the interpreted result may be ungrammatical in case that there is a possibility that the sentence of the translation result may be ungrammatical.  
     CONSTITUTION: In interpretation of plural words, translation of word to word is performed independently of the order of words and grammar. When these words are observed as one sentence, the sentence of the interpreted result is ungrammatical normally though the input sentence is grammatical. Consequently, if there is a possibility that the sentence of the interpreted result may be ungrammatical, a pertinent indication symbol of symbol display part 5 is lit simultaneously with outputting of the interpreted result to report this possibility.

Title: Frictional damper provided with speed-up mechanism
Inventor: HIKITA KENJI
IPC: F16F7/10
Filed: 1982-03-31
Abstract: PURPOSE:To obtain the damping effect of a large capacity with no increase in the mass of an inertia body, by increasing the rotational speed of a recirculating ball member with the use of a differential gear speed-up mechanism. CONSTITUTION:A screw rod 3 rotates a ball recirculating member 4 when a relative displacement between a main casing and a subcasting 2 with a low acceleration is brought about due to thermal deformation or the like. The rotation of the member 4 is transmitted to a resilient member 8 through a differential gear speed-up mechanism comprising gears 6, 7, 9. Since an acceleration in the rotation of the recirculating ball member 4 is small, it is transmitted to an inertia body 11 through balls 12, and therefore, a friction member 10 rotates with a gap being defined between the friction member 10 and a main case annular friction member 1e so that an object to be damped is permitted to be slowly displaced, smoothly. A relative rotation comes about between the inertia body 11 and the resilient member 8 when a relative displacement with a high acceleration is brought about therebetween, resulting in a positional shifting between recesses 8b, 11a, and therefore, the balls 12 roll up on a slant surface so that the friction member 10 is engaged with the annular friction member 1e. Thereby the damping operation is carried out.
