Title: Telephone set
Inventor: SAKAMOTO YUICHI
IPC: H04M1/274
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To conduct new dialing by operating a registration data transmission means during dialing without starting dialing with a hook-off state set again after transition to an on-hook state during dialing. SOLUTION: In the case of making a phone call to other party, when an automatic dial key 1 or an abbreviation dial key 2 is depressed, a microcomputer 9 opens a DC loop 11 to open the connection to a telephone line at once. The microcomputer 9 closes the DC loop 11 at a prescribed time interval so that an exchange mis-discriminates it to be hooking thereby closing the telephone line. Since a call tone is sent from the exchange, the microcomputer 9 confirms it and sends a telephone number registered as automatic dial data or abbreviation dial data. Thus, a phone call is made to the other party without the need for hooking on the telephone set 6 at once and then hooking off the telephone set 6 again or depression of a speaker phone key 5 twice.

IPC: H01L21/266
Filed: 1990-08-28
Abstract: PURPOSE:To improve ion implantation blocking performance by employing a patterned multilayer film as an ion implantation mask after formation of a metal film on a resist film. CONSTITUTION:A positive photoresist film 11, an aluminum film 12 and another positive photoresist film 13 are applied sequentially on a substrate and then the another positive photoresist film 13 is patterned.
