Patent number: 11959039Abstract: A heating device includes a rotating body, a heating source, a rotating body holder, and a lubricant of liquid or semi-solid. The heating source heats the rotating body. The rotating body holder holds both longitudinal ends of the rotating body rotatably. The lubricant of liquid or semi-solid adheres to the rotating body holder. A temperature of the rotating body holder is lower than a generation temperature of fine particles of the lubricant.Type: GrantFiled: March 7, 2023Date of Patent: April 16, 2024Assignee: Ricoh Company, Ltd.Inventors: Takayuki Andoh, Masahiro Samei, Kota Shiodera, Toshiyuki Kabata, Hiroshi Yoshinaga

Publication number: 20220066210Abstract: A virtual image display device displays a virtual image by projecting a display light of an image toward a projection unit, and includes: a display unit configured to emit the display light; and a diffraction reflection element configured to reflect the display light emitted from the display unit by diffraction. The diffraction reflection element has a plate shape along a horizontal plane. The diffraction reflection element is configured to emit the display light toward the projection unit arranged above the diffraction reflection element when the display light is incident, and is set such that an angle of incidence on the diffraction reflection element is larger than an angle of emission from the diffraction reflection element.Type: ApplicationFiled: November 11, 2021Publication date: March 3, 2022Inventors: Hiroshi ANDOH, Kazuhisa ONDA, Yujiro MIZOBUCHI

Patent number: 9817009Abstract: It is an object of certain embodiments of the present invention to suppress variance in measurement results from a biological information measurement device and enhance measurement accuracy. A biological information measurement device comprises a main case having a sensor mounting component for mounting a sensor that senses biological information, a measurement component that connects to the sensor mounting component, a controller that connects to the measurement component, a first timer that connects to the controller, and a second timer that connects to the controller. The controller has a measurement mode in which a measurement operation is performed through the measurement component. In the measurement mode, the controller executes the measurement operation based on a preset measurement timing using the first timer, and determines the suitability of the measurement operation based on the preset measurement timing, using the second timer.Type: GrantFiled: September 27, 2013Date of Patent: November 14, 2017Assignee: Panasonic Healthcare Holdings Co., Ltd.Inventors: Yuichi Sugiue, Hiroshi Andoh

Patent number: 8870335Abstract: A liquid discharge state detection device includes a light emitting element that emits a light beam; and a light receiving element that is placed at a position shifted from a beam diameter of the light beam. The light receiving element receives scattered light generated when the light beam collides with a liquid droplet. A discharge state of the liquid droplet is detected based on a received light amount of the received scattered light. The liquid discharge state detection device further includes an analyzer in the forward direction from the light receiving element. The analyzer detects the scattered light having a polarization direction the same as a polarization direction of the light beam emitted by the light emitting element. The light receiving element receives the scattered light that has passed through the analyzer.Type: GrantFiled: December 7, 2012Date of Patent: October 28, 2014Assignee: Ricoh Company, Ltd.Inventor: Hiroshi Andoh
