Patent number: 5258980Abstract: A radio channel switching control method for a digital mobile communication system employing TDMA techniques, in which a mobile station stores the synchronized state in the current channel, switches the current channel to a new one and performs a pull-in operation for a predetermined period of time and stores the synchronized state obtained by the pull-in operation. The mobile station establishes synchronism with the new channel by repeating a sequence of steps of performing communication again in the synchronized state in the current channel and performing the pull-in operation in the stored synchronized state for the new channel. Thus, it is possible to implement radio channel switching free from momentary interruption of communication, by maintaining communication in the current channel until synchronization with the new channel is established and communication is permitted.Type: GrantFiled: April 24, 1991Date of Patent: November 2, 1993Assignee: Nippon Telegraph and Telephone CorporationInventors: Akihiro Maebara, Seizo Onoe, Fumiyuki Adachi, Masaharu Hata, Toshinori Fujii

Patent number: 4708545Abstract: A method for drilling reference holes in a multi-layer printed wiring board assembly, in which drilling position marks provided on inner-layer circuit board in the assembly are roughly detected through each of two outer-layer boards of the assembly, a spot-facing is made with respect to the outer-layer boards at roughly detected points of the marks, and thereafter the marks are precisely detected at the faced spots. Positions for drilling the reference holes can be thereby determined at the spots precisely in close proximity to the internally provided drilling position marks, to allow the drilling performed very accurately in simpler and economical manner.Type: GrantFiled: November 14, 1985Date of Patent: November 24, 1987Assignee: Matsushita Electric Works, Ltd.Inventors: Toshinori Fujii, Shinji Okamoto
