Patent number: 10981806Abstract: To provide a sterilizer preventing ultraviolet ray absorption in a body of a case body and emitting ultraviolet rays to a portion to be sterilized without involving positioning with high accuracy. A sterilizer 1a has a case body 2 containing a member having an ultraviolet-ray transmission property and a flow passage formed thereinside and an ultraviolet-ray irradiation portion 3 irradiating a predetermined portion of a member configuring the case body 2 with ultraviolet rays, in which ultraviolet rays emitted from the ultraviolet-ray irradiation portion 3 travel in a body of the case body 2 to be radiated at least from an end surface on an output end side of the case body 2.Type: GrantFiled: June 26, 2018Date of Patent: April 20, 2021Assignee: ASAHI KASEI KABUSHIKI KAISHAInventors: Hiroyuki Kishi, Sho Sugiyama, Shinji Miya

Patent number: 7406301Abstract: A modulation-demodulation apparatus of a relatively simple arrangement is able to prevent a bad influence caused due to interference between two local oscillators and a portable wireless communication apparatus uses this modulation-demodulation apparatus. In a modulation-demodulation apparatus using a local oscillator (105) for use in direct conversion type of a receiving system and a local oscillator (104) for use with a transmitting system, a ratio (C/D) between a reception frequency and an oscillation frequency of the reception local oscillator (105) and a ratio (A/B) between a transmission frequency and an oscillation frequency of the transmission local oscillator are made different from each other.Type: GrantFiled: April 30, 2003Date of Patent: July 29, 2008Assignees: Sony Ericsson Mobil Communicatons Japan, Inc., Asahi Kasei EMD CorporationInventors: Masaaki Kasahara, Shinji Miya, Kuniyuki Nakayama

Patent number: 6931237Abstract: A communication apparatus is provided which employs two oscillators to generate a transmission signal and a reception signal, and prevents harmful spurious components from being produced. As shown in FIGS. 9A and 9B, the oscillation frequency fVCO2 of a VCO 2 is given by fVCO2=N×(2×fDD), where fDD is the difference between the transmit frequency fT and receive frequency fR. A 3/(2×N) frequency multiplier outputs a signal with a frequency 3×fDD, and a divide-by-N circuit (2/(2×N) frequency multiplier) outputs a signal with a frequency 2×fDD. Thus the transmit intermediate frequency fTIF is given by fTIF=3×fDD, and the receive intermediate frequency fRIF is given by fRIF=2×fDD. The oscillation frequency fVCO1 of a VCO 1 is fCH. The transmit frequency fT is given by fT=fCH+fTIF=fCH+3×fDD. The circuit can prevent a transmission spurious problem to its own reception band.Type: GrantFiled: February 21, 2002Date of Patent: August 16, 2005Assignee: Asahi Kasei Microsystems Co., Ltd.Inventors: Shinji Miya, Nobuo Saito

Publication number: 20030190901Abstract: A direct conversion receiving unit includes an oscillation circuit (50) whose oscillation frequency fvco is (N/(N+1))×fR, where fR is a receiving frequency. The output of the oscillation circuit (50) is divided into two parts, one of which is converted to the frequency of (1/(N+1))×fR by a divide-by-N circuit (52). Mixing the two frequencies (1/(N+1))×fR and fvco=(N/(N+1))×fR generates the frequency fR, which is supplied to conversion mixers (38 and 44) as a local input. The receiving unit requires only one oscillation circuit, and excludes all the circuits that handle a frequency higher than fR, enabling a small size and low current consumption configuration.Type: ApplicationFiled: April 4, 2003Publication date: October 9, 2003Applicant: ASAHI KASEI MICROSYSTEMS CO., LTDInventors: Shinji Miya, Yuro Yoshizawa
