Publication number: 20050158793Abstract: This invention provides a method wherein a protein sparingly soluble in water, or a protein in a hardly extractable state, is detected sharply and easily in subsequent immunoreaction while high efficiency of extraction from a sample is maintained. Disclosed is a highly sensitive and easy immunoassay characterized in that a water-sparingly-soluble protein in a sample, or a protein in a hardly extractable state, is extracted/solubilized with an aqueous solvent containing an ionic surfactant at relatively high concentration, and then the protein in the extract is detected directly by an antibody raised against the protein previously denatured with the ionic surfactant.Type: ApplicationFiled: March 3, 2004Publication date: July 21, 2005Inventors: Shiroo Muraoka, Yumiko Watanabe, Masatoshi Sakai, Tsutomu Honjoh

Patent number: 5805678Abstract: A facsimile system with the body thereof usable as a subunit of a cordless telephone is disclosed. A parent unit is connected to the telephone line. A facsimile subunit is connected by radio to the parent unit. A telephone subunit is also connected by radio to the parent unit. A circuit included in the parent unit detects a signal indicating that the other party is in facsimile transmission mode. When a call signal is detected from the telephone line, the parent unit connects the line. When a CNG signal is detected, on the other hand, the parent unit connects the facsimile subunit by radio. In the case where a CNG signal is not detected, the parent unit starts the ring-up tone on the telephone subunit. An AGC circuit and a voice mute circuit are included in the parent unit.Type: GrantFiled: October 20, 1993Date of Patent: September 8, 1998Assignee: Hitachi, Ltd.Inventors: Teiji Okamoto, Seiji Tanaka, Shinya Imanishi, Toru Tanaka, Tetsuo Shinagawa, Yumiko Watanabe

Patent number: 5748715Abstract: A facsimile apparatus which utilizes a dialing signal of a tone signal and can be used as a called-side communication apparatus to print desired character string information through a simple operation of a calling-side telephone set, and also a facsimile communication method in the facsimile apparatus. In the called-side facsimile apparatus, a character string information memory stores therein a plurality of character string information and unique numbers associated therewith; whereas a character information memory stores therein image information corresponding to the respective character string information. When a user of the calling-side communication apparatus enters a number corresponding to desired character string information, this causes a dialing signal indicative of the number to be transmitted to the facsimile apparatus.Type: GrantFiled: September 21, 1995Date of Patent: May 5, 1998Assignee: Hitachi, Ltd.Inventors: Tetsuo Shinagawa, Yumiko Watanabe, Akio Shinagawa, Fumitaka Ito
