Title: Method of press fitting shaft
Inventor: TAKEUCHI SHIYOUICHI
IPC: B23P11/00
Filed: 1984-04-11
Abstract: PURPOSE:To reduce fraction defective by providing an annular groove on an end of a shaft to press fit the shaft elastically transformed into a hole in a base material. CONSTITUTION:A shaft 2 is formed on an end with an annular groove 3. When the shaft is press fitted into a hole 1 in a base material 4, a front end 3' of the annular groove 3 is elastically transformed by the press fit reaction, while penetrating through the bore 1' in the hole 1 so that the penetrating barr is absorbed by the annular groove 3 and the bore 1' has the diameter expanded. By this expansion, the front end 3' of the annular groove 3 can form properly the press fit allowance for the rear end 3'' even if the press fit allowance is made somewhat large so that the rear end 3'' and the bore 1' of the hole 1 obtain pressure with accuracy as high as that of punishing working. By this constitution can be reduced fraction defective.

Title: Telephone set
Inventor: HAYAKAWA KIYOSHI
IPC: H04M3/42
Filed: 1988-03-25
Abstract: PURPOSE:To make unnecessary an operation to return a sound volume adjusting volume when ringing off by controlling a receiving sound volume through a private branch exchange and returned the receiving sound volume to an initial one when being restored. CONSTITUTION:When a user turns up the receiving sound volume because of a long-distance call, he switches on/off an input switch 8 based on the present receiving sound volume. A private branch exchange 9 controls an amplifier 4 through a control line 12 and a control circuit 7 and sets the necessary receiving sound volume based on the information of a receiving sound setting signal volume. When ringing off, when the user of a telephone set 1 is restored, the private branch exchange 9 first reads out the receiving sound volume setting signal stored temporarily controls the setting of the amplifier 4 so as to return it to its initial condition set beforehand through the control line 12 and the control circuit 7. Thus, next, for example, when the telephone set 1 is connected to another telephone set of a normal line which is not for the long-distance call, the user of the telephone set 1 need not return the receiving sound volume to the initial one.

Abstract: PURPOSE:To reduce the English burden on the users of an English work processor. CONSTITUTION:When a Japanese character string is inputted to a Japanese work input part 1, the character string is sent to a Japanese work morpheme analyzing part 2. The part 2 divides the inputted Japanese character string into the morphemes with use of the Japanese work pat of a dictionary 6 and allocates the English expressions of the dictionary 6 to each morpheme. An English work processing part 3 refers to the dictionary 6 to obtain plural English expression to an inputted Japanese expression. These English expressions are compared with the morpheme analyzing result of the inputted Japanese character string. Thus plural English expressions are produced to the inputted Japanese work and stored in a storage part 5. An English expression display part 4 shows in steps the English equivalents, the conjugation and the character types for plural English expression strings stored in the part 5. Thus a final English character string is selected and decided.
