Patent number: 11994315Abstract: An air-conditioning apparatus includes a heat-source detection unit provided at the front of a housing. The heat-source detection unit includes an infrared sensor that detects a heat source in an air-conditioned space and a supporting member that supports the infrared sensor. The supporting member is rotated about an axis that extends in a vertical direction. Part of the infrared sensor that corresponds to the field of view thereof is exposed when the infrared sensor faces the air-conditioned space, and the part of the infrared sensor is concealed when the infrared sensor does not face the air-conditioned space.Type: GrantFiled: August 8, 2019Date of Patent: May 28, 2024Assignee: Mitsubishi Electric CorporationInventors: Masayuki Oishi, Hiroshi Hirosaki, Yohei Koyanagi, Kazuki Nagai

Patent number: 10318825Abstract: In a vehicle-mounted image recognition apparatus, a resolution of an image projected on an imaging plane of an image sensor is different at a position away from a center between a circumferential direction and a radial direction. To make a circumferential resolution higher than a radial resolution, at least a lower half of the imaging plane is located closer to a circumferential focus than a middle of a radial focus and the circumferential focus at a position off the optical axis center of the image projected on the image sensor through the image-forming optical system. This is achieved by adjusting the position of the imaging plane when manufacturing or by selecting a lens with high circumferential resolution. This apparatus improves recognition accuracy in recognizing traffic lanes without using an expensive lens exhibiting high resolution both in the circumferential direction and in the radial direction.Type: GrantFiled: October 25, 2017Date of Patent: June 11, 2019Assignees: NIDEC COPAL CORPORATION, NIDEC ELESYS CORPORATIONInventors: Yuta Nakamura, Yohei Nagai, Yushi Takehara, Naoya Takeda

Patent number: 4351212Abstract: An electronic musical instrument comprises a note code producer for producing note codes respectively having n bits representing juxtaposed notes aligned by a semitone interval step. The note codes to be generated are selected from a binary code table consisting of successively aligned binary values corresponding to an order of alignment of the notes in a musical scale and the table omits either one of the largest and smallest values to be represented by the lowest m bits (n>m). A modified note code generator produces modified note codes by repetitively adding the lowest m bits of each note code to further lower order digits below the least significant bit of each note code, and a sound system generates musical tones having frequencies corresponding to the modified note codes.Type: GrantFiled: April 21, 1980Date of Patent: September 28, 1982Assignee: Nippon Gakki Seizo Kabushiki KaishaInventors: Shimaji Okamoto, Yohei Nagai

Patent number: 3960044Abstract: A keyboard arrangement having an after-control signal detecting sensor means connected to electric circuitry to use the signal generated by this sensor means as an after-control signal for controlling various musical effects. This sensor means comprises a conductive flexible first electrode, a conductive second electrode, and a conductive elastic member, such as a conductive rubber, interposed between the first and second electrodes and adhered thereto, the conductive elastic member varying its resistance according to the degree by which it is compressed and deformed. With this arrangement, the resistance of the conductive elastic member will vary as it is compressed and/or deformed by playing keys in proportion to the positions of the depressed keys. This variation of resistance is employed so as to after-control the tone coloring, tone volume, vibrato, and other musical effects.Type: GrantFiled: October 17, 1974Date of Patent: June 1, 1976Assignee: Nippon Gakki Seizo Kabushiki KaishaInventors: Yohei Nagai, Kiyoshi Kawamura

Patent number: 3943812Abstract: A touch responsive sensor for an electronic keyboard musical instrument of a variable capacitor type, which comprises a pair of electrodes spaced apart from each other, and an intermediate electrode interposed between the pair of electrodes and separated from each of the pair of electrodes by a dielectric. The intermediate electrode is movable from near one of the pair of electrodes toward the other of the pair of electrodes in accordance with the movement of each playing key of the electronic musical instrument. Thus, in the course of a key depressing movement, first and second touch responsive controlling signals are derived from, respectively, between the one of the pair of electrodes and the intermediate electrode and between the other of the pair of electrodes and the intermediate electrode in accordance with the variation of capacitance produced therebetween.Type: GrantFiled: November 1, 1974Date of Patent: March 16, 1976Assignee: Nippon Gakki Seizo Kabushiki KaishaInventors: Yohei Nagai, Masatada Wachi
