Publication number: 20240128049Abstract: An object of the invention is to provide an electron microscope capable of obtaining a sufficient energy resolution without forming a long drift space and capable of attaining high energy discrimination detection performance with approximately the same device size as in the related art. The electron microscope according to the invention includes a pulsed electron emission mechanism configured to emit an electron beam in a pulsed manner, and discriminates energy of signal electrons by discriminating the signal electrons, which are emitted from a sample by irradiating the sample with the electron beam, according to a time of flight (see FIG. 2).Type: ApplicationFiled: August 31, 2021Publication date: April 18, 2024Inventors: Katsura TAKAGUCHI, Takashi OHSHIMA, Hideo MORISHITA, Yoichi OSE, Junichi KATANE, Toshihide AGEMURA, Michio HATANO

Publication number: 20240120168Abstract: An electron beam emitted from a photoexcited electron gun is increased in luminance. An electron gun 15 includes: a photocathode 1 including a substrate 11 and a photoelectric film 10; a light source 7 that emits pulsed excitation light; a condenser lens 2 that focuses the pulsed excitation light toward the photocathode; and an extractor electrode 3 that faces the photocathode and that accelerates an electron beam generated from the photoelectric film by focusing the pulsed excitation light by the condenser lens, transmitting the pulsed excitation light through the substrate of the photocathode, and causing the pulsed excitation light to be incident on the photocathode. The pulsed excitation light is condensed at different timings at different positions on the photoelectric film of the photocathode.Type: ApplicationFiled: October 31, 2019Publication date: April 11, 2024Applicants: Hitachi High-Tech Corporation, Hitachi High-Tech CorporationInventors: Takashi Ohshima, Hideo Morishita, Tatsuro Ide, Naohiro Kohmu, Momoyo Enyama, Yoichi Ose, Toshihide Agemura, Junichi Katane

Patent number: 8295390Abstract: A communications device 100, which performs data communication, includes an AC cycle sensor 30 which is connected to a power line 106 supplied with an a.c. voltage and generates a synchronous signal SS at timing of an a.c. voltage waveform AC of the power line 106; a data communicator 10 for performing data communication; and a communications controller 20 which performs communication of a control signal including information showing at least one of a communications device and a communications standard and controls the data communicator 101. When the a.c. voltage supplied to the power line 106 is an N-phase and when the cycle of the a.c. voltage waveform is T, data communication to be performed in a communication period subsequent to the period is controlled on the basis of the control signal included in the period of T/2M on condition that M is a natural multiple of N.Type: GrantFiled: December 30, 2009Date of Patent: October 23, 2012Assignees: Panasonic Corporation, Mitsubishi Electric Corporation, Sony CorporationInventors: Hisao Koga, Yuji Igata, Go Kuroda, Koji Ikeda, Akio Kurobe, Hirotoshi Yamada, Hiromu Okamoto, Yoshinori Mizugai, Takehiro Sugita, Junichi Ohshima, Shigeru Takasu

Publication number: 20070064783Abstract: An in-home-system master station of an in-home communication system detects a frequency band (a channel number corresponding to a data communication subchannel) or a time slot used by each station of an access communication system, using a coexistence signal subchannel. Based on the detected information, the in-home-system master station determines a frequency band or a time slot to be used in the in-home communication system to which the in-home-system master station belongs, so as not to avoid overlapping the frequency or time slot used in the access communication system, and informs each in-home-system slave station of the determined frequency band or time slot.Type: ApplicationFiled: July 5, 2006Publication date: March 22, 2007Inventors: Go Kuroda, Akio Kurobe, Koji Ikeda, Hisao Koga, Yuji Igata, Hirotoshi Yamada, Yoshinori Mizugai, Hiromu Okamoto, Junichi Ohshima, Shigeru Takasu, Takehiro Sugita
