Publication number: 20240151460Abstract: A refrigerator comprising a cabinet, a door configured to open and close an opening of the cabinet, and an outside air heat inductor arrangeable inside the door to extend toward the cabinet from a front portion of the door. The outside air heat inductor includes a first heat transfer path forming member configured to transfer outside air heat from outside the refrigerator toward a surface of the cabinet, and a second heat transfer path forming member arrangeable between the first heat transfer path forming member and an inside of the cabinet such that while the second heat transfer path forming member is arranged between the first heat transfer path forming member and the inside of the cabinet, the second heat transfer path forming member receives the outside air heat and prevents cold air within the cabinet from being transferred to the first heat transfer path forming member.Type: ApplicationFiled: January 17, 2024Publication date: May 9, 2024Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hitoshi TAKASE, Ryota AOKI, Tomohiko MATSUNO, Makoto SHIBUYA

Patent number: 11946858Abstract: The purpose of the present invention is to allow a clean airflow around a substrate to reliably move downward of the substrate in an examination device in which clean air is supplied to an inspection chamber. This examination device is provided with a rectifying plate (see FIG. 4A) which covers a part of the upper surface of a stage for mounting a substrate, and is disposed between a gas supply unit and the stage to block an airflow toward the substrate.Type: GrantFiled: October 7, 2019Date of Patent: April 2, 2024Assignee: HITACHI HIGH-TECH CORPORATIONInventors: Yoshihiro Satou, Toshio Masuda, Hitoshi Matsuno, Kei Shibayama, Osamu Yoshimura, Yuichirou Iijima

Patent number: 11933533Abstract: A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.Type: GrantFiled: June 5, 2020Date of Patent: March 19, 2024Assignee: Samsung Electronics Co., Ltd.Inventors: Tomohiko Matsuno, Tomoharu Iwamoto, Makoto Shibuya, Tatsuya Seo, Hitoshi Takase

Patent number: 10938325Abstract: A self-oscillating piezoelectric actuator drive circuit includes a integrating circuit; an inverter (INV1), inverters (INV2 and INV3) inverting an output signal of the inverter (INV1), sense resistors (Rs1 and Rs2) connected to output sides of the inverters (INV2 and INV3), a positive feedback resistor (Rfb2) feeding back an output signal of the inverters (INV2 and INV3) to the integrating circuit; and a negative feedback resistor (Rfb1) feeding back a voltage generated from the sense resistors (Rs1 and Rs2, Rs1<Rs2 in terms of a resistance value) to the integrating circuit. In a startup state, the sense resistor (Rs2) and the inverter (INV3) are selected, and in an operating state after the startup state, the sense resistor (Rs1) and the inverter (INV2) are selected.Type: GrantFiled: October 18, 2016Date of Patent: March 2, 2021Assignees: NEW JAPAN RADIO CO., LTD., MURATA MANUFACTURING CO., LTD.Inventors: Yasuyuki Endou, Toshio Imanishi, Hitoshi Matsuno

Patent number: 10461697Abstract: An oscillation circuits that provides stable oscillations even when the amount of phase rotation of a piezoelectric resonator is small or fluctuates. The oscillation circuit includes a first amplifier having an input and an output, and a piezoelectric resonator connected between the input and the output of the first amplifier. Moreover, the oscillation circuit feeds, back to the input, a current flowing from the output of the first amplifier to the piezoelectric resonator. The oscillation circuit further includes an alternating-voltage waveform shaping circuit that applies, to the piezoelectric resonator, an alternating-voltage waveform having rising portions sharper than those of a sine wave.Type: GrantFiled: February 27, 2017Date of Patent: October 29, 2019Assignee: MURATA MANUFACTURING CO., LTD.Inventors: Toshio Imanishi, Hitoshi Matsuno
