Publication number: 20240129669Abstract: A distribution system includes a device control circuit that receives a first sound signal and a second sound signal that are related to a performance sound to be distributed. The device control circuit also receives meta-data indicating a type of the first sound signal and a type of the second sound signal. The device control circuit also receives sound environment data indicating a sound characteristic of a sound appliance. Based on a combination of the type of the first sound signal and the sound characteristic or a combination of the type of the second sound signal and the sound characteristic, the device control circuit controls the first sound signal or the second sound signal to be output to the sound appliance.Type: ApplicationFiled: December 26, 2023Publication date: April 18, 2024Inventors: Masaru TANAKA, Yoshifumi MIZUNO, Takashi MORI, Akira MAEZAWA, Ryunosuke DAIDO, Kazunobu KONDO

Publication number: 20240019055Abstract: A ring body to be provided in a pipe joint which can prevent a spigot from separating from a socket by a spigot protrusion engaging with a lock ring from the back side of the socket in the separation direction A of the spigot. The ring body includes a main body part which is inserted into between the inner peripheral surface of the socket and the outer peripheral surface of the spigot to be provided in the pipe joint, and a deviation prevention member that prevents the main body part from deviating to the opening end side of the socket, wherein the main body part moves the spigot in the pipe radial direction with respect to the socket, thereby reducing deviation in the pipe radial direction between the pipe axis of a first pipe and the pipe axis of a second pipe.Type: ApplicationFiled: October 5, 2020Publication date: January 18, 2024Applicant: KUBOTA CORPORATIONInventors: Shozo KISHI, Keita ODA, Ryunosuke TANAKA

Publication number: 20230400128Abstract: A pipe joint is provided in which a seal member insertion space 14 is formed between a first tapered surface 8 of a socket 5 and an outer circumference of a spigot 3, a seal member 15 is inserted into the seal member insertion space 14, and a gland 17 that presses the seal member 15 into the seal member insertion space 14 is externally fitted to the spigot 3. The seal member 15 has a bulb part 26 at one end part thereof. A guide part 29 that guides the bulb part 26 from an opening end face 16 of the socket 5 into the seal member insertion space 14 is formed on the inner circumference of the socket S. The guide part 29 has a second tapered surface 30. An angle of inclination of the second tapered surface 30 is greater than an angle of inclination of the first tapered surface 8.Type: ApplicationFiled: October 29, 2021Publication date: December 14, 2023Applicant: KUBOTA CORPORATIONInventors: Ryunosuke TANAKA, Keita ODA, Shozo KISHI

Patent number: 11746937Abstract: A pipe joint in which a seal body and a spacer are mounted from the insides of pipes, wherein: a spigot of one pipe is inserted into a socket of the other pipe; and an annular accommodation space is formed between the inner circumference of the socket and the outer circumference of the spigot. Inside the accommodation space are accommodated: a seal body for sealing the gap between the socket and the spigot; a push ring that presses the seal body to keep the seal body in a compressed state; and a spacer that maintains the interval between the push ring and the deep end of the socket in the pipe axial direction.Type: GrantFiled: March 19, 2019Date of Patent: September 5, 2023Assignee: KUBOTA CORPORATIONInventors: Shozo Kishi, Kazuya Ito, Kazuma Harada, Keita Oda, Ryunosuke Tanaka, Kohei Ikeda, Yuito Komaru

Publication number: 20230091354Abstract: In a pipe joint, a spigot is inserted into a socket; a lock ring is accommodated in a lock ring-accommodating groove formed in the inner circumference of the socket; and an engaging part formed in the outer circumference of the spigot, wherein the engaging part engages with the lock ring from a back side of the socket in a separation direction A of the spigot, thereby preventing the spigot from separating from the socket. The engaging part is formed at a position receding from a distal end of the spigot in the separation direction A of the spigot. A bending suppressing member for restricting the socket and the spigot in a bending direction C is provided between the inner circumference of the socket and the outer circumference of the spigot in the range between the distal end of the spigot and the engaging part.Type: ApplicationFiled: October 5, 2020Publication date: March 23, 2023Applicant: KUBOTA CORPORATIONInventors: Shozo KISHI, Keita ODA, Ryunosuke TANAKA

Patent number: 11333278Abstract: A pipe-joining centering device aligns, with an axial center of one pipe, an axial center of another pipe when a spigot of the other pipe is to be inserted into a socket of the one pipe. The pipe-joining centering device includes a support member configured to support an end part of the spigot. The support member is tiltable in a pipe radial direction between an inner peripheral surface of the socket and an outer peripheral surface of the spigot. The pipe-joining centering device also includes a position adjustment member configured to tilt the support member in the pipe radial direction. The support member and the position adjustment member are supported on the inner peripheral surface of the socket.Type: GrantFiled: December 20, 2019Date of Patent: May 17, 2022Assignee: KUBOTA CORPORATIONInventors: Shozo Kishi, Keita Oda, Ryunosuke Tanaka, Hideki Nakaya
