Patent number: 11822274Abstract: A fixing device includes an annular belt having an outer circumferential surface, and a facing member that faces the outer circumferential surface of the annular belt to form a nip region. The annular belt is configured so that in measurement of a hardness of the outer circumferential surface using a hardness tester, a ratio (A/B) of a first hardness value (A) to a second hardness value (B) is 0.738 or more and 0.837 or less. The first hardness value (A) represents a measured value at a time when a measurement time corresponding to a time required for a predetermined point on the outer circumferential surface to pass through the nip region has elapsed after start of the hardness measurement. The second hardness value (B) represents a measured value at a time when the measured value by the hardness tester is saturated.Type: GrantFiled: December 16, 2022Date of Patent: November 21, 2023Assignee: Oki Electric Industry Co., Ltd.Inventor: Yoshihiro Kanno

Patent number: 10461163Abstract: A three-dimensional memory device includes an alternating stack of insulating layers and electrically conductive layers located over a substrate. Memory stack structures are located in a memory array region, each of which includes a memory film and a vertical semiconductor channel. Contact via structures located in the terrace region and contact a respective one of the electrically conductive layers. Each of the electrically conductive layers has a respective first thickness throughout the memory array region and includes a contact portion having a respective second thickness that is greater than the respective first thickness within a terrace region. The greater thickness of the contact portion prevents an etch-through during formation of contact via cavities for forming the contact via structures.Type: GrantFiled: November 15, 2017Date of Patent: October 29, 2019Assignee: SANDISK TECHNOLOGIES LLCInventors: Senaka Krishna Kanakamedala, Yoshihiro Kanno, Raghuveer S.

Patent number: 5695657Abstract: A magneto-resistance effect type thin-film magnetic head for detecting reproduced signals by the magneto-resistance effect, which is suitable for detecting reproduced signals by magneto-resistance effects, is disclosed. The thin-film magnetic head includes a two-layered magneto-resistance effect element made up of a first magneto-resistance effect film and a second magneto-resistance effect film of substantially the same width as the first magneto-resistance effect film, layered with a non-magnetic insulating film in-between. Since the magneto-static coupling is produced between the first and second MR films, the magnetic state between the first and second MR films is stabilized. The film thickness contributing to the playback output can be reduced as in the case of a single-layer magnetic head constituted by a single-layer MR film for realizing a high playback output.Type: GrantFiled: June 27, 1996Date of Patent: December 9, 1997Assignee: Sony CorporationInventors: Takuji Shibata, Yoshihiro Kanno, Tadayuki Honda, Akio Takada, Yukio Kondo, Tadao Suzuki
