Patent number: 11986134Abstract: To dispense a predetermined length of a sheet hygienically. In a sheet dispensing device, a sheet feeding mechanism feeds out a predetermined length for use of a sheet from a sheet dispensing port, and at this time, a part, of the sheet, located upstream of the sheet dispensing port in terms of a feeding direction of the sheet is held by a driving roller and a driven roller. The driven roller is biased by leaf springs to be pressed toward the driving roller. Consequently, the sheet is dispensed while hanging down from the sheet dispensing port. When a user pulls down the hanging sheet while holding it, the sheet is cut from the vicinity of a held part, so that the user can take the predetermined length for use of the sheet hygienically.Type: GrantFiled: August 19, 2019Date of Patent: May 21, 2024Assignee: MATSUO INDUSTRIES, INC.Inventors: Motoi Matsuo, Yuji Sekitomi, Mikiya Ichikawa, Kazushi Akutsu, Noriyuki Heike

Publication number: 20230102281Abstract: A wet sheet with a predetermined length is securely provided while drying is prevented. When a motor control part receives a detection signal from a hand hovering sensor, a motor is driven from a standby state to rotate a driving roller. When a cutting line is detected by a cutting line detecting sensor, the driving of the motor is continued until a predetermined time set beforehand in which the detected cutting line reaches the side downstream of a contact point between the driving roller and a driven roller in terms of the feeding direction has elapsed, to be stopped. The detected cutting line is located downstream of the contact point between the driving roller and the driven roller in terms of the feeding direction. In front of the detected cutting line, the wet sheet for one sheet is present and is detected by the sheet detecting sensor.Type: ApplicationFiled: January 21, 2021Publication date: March 30, 2023Applicant: MATSUO INDUSTRIES, INC.Inventors: Motoi MATSUO, Yuji SEKITOMI, Mikiya ICHIKAWA, Kazushi AKUTSU, Noriyuki HEIKE

Patent number: 4751783Abstract: Disclosed is an azimuth determination apparatus attached to a motor vehicle for determinating the forward direction of the vehicle. The azimuth determination apparatus includes an azimuth sensor for generating orthogonal first and second signals indicative of the forward direction of the vehicle. Two azimuth vectors are obtained on the basis of the orthogonal first and second component signals, first components of the two azimuth vectors being maximum and minimum. The determination is made in terms of the fact that the difference between second components of the two azimuth vectors is below a predetermined value. In accordance with the determination, the orthogonal first and second component signals are corrected on the basis of said two azimuth vectors so that the accurate moving direction of the motor vehicle can be obtained irrespective of the remanence of the vehicle.Type: GrantFiled: June 3, 1987Date of Patent: June 21, 1988Assignee: Nippondenso Co., Ltd.Inventors: Katsuhiro Ina, Yuji Hirabayashi, Susumu Akiyama, Kazushi Akutsu, Kiyohumi Kage

Patent number: 4739560Abstract: An azimuth calculation apparatus includes an azimuth sensor mounted on a moving body for detecting a direction of the moving body, the azimuth sensor having an excitation winding wound on an annular magnetic core and a pair of output windings wound on the core perpendicularly relative to one another to produce first and second output signals therefrom in response to energization of the excitation winding. The calculation apparatus is arranged to detect a temperature of the azimuth sensor and to determine a pair of correction values based on the detected temperature of the azimuth sensor so as to correct each value of the first and second output signals from the output windings to an optimal value for calculating the direction of the moving body in dependence upon the corrected output signals from the output windings.Type: GrantFiled: October 9, 1986Date of Patent: April 26, 1988Assignee: Nippondenso Co., Ltd.Inventors: Kazushi Akutsu, Hitoshi Ichikawa

Patent number: 4513377Abstract: In a vehicle-mounted navigator, a control unit reads map data from a memory unit and displays a corresponding road map on a CRT display unit. In response to signals from a distance sensor and a direction sensor, the present position in relation to the running of the automotive vehicle is computed to display by superimposition the present position on the road map display of the display unit. When the computed present position has reached to a predetermined portion of an adjacent area, the map data of the road map adjacent to the road map on display is read from the memory unit and a corresponding road map is displayed on the display unit manually or automatically. In accordance with this updated display, the present position display is moved to a corresponding position on the updated road map display.Type: GrantFiled: June 8, 1982Date of Patent: April 23, 1985Assignee: Nippondenso Co., Ltd.Inventors: Koshi Hasebe, Kunio Miura, Takashi Ono, Kazushi Akutsu, Kazuaki Minami

Patent number: 4504913Abstract: An automotive navigator using a microcomputer displays a car position by a cursor on a road map displayed on a CRT screen. The navigator uses a cassette tape which stores a plurality of road map data and several kinds of reduced map data and expanded map data. It also uses a group of manual switches including a switch for changing the displayed area, a switch for selecting an expanded map or reduced map and a switch for moving the cursor position. Necessary data are displayed on the screen by the state of each switch. A region corresponding to the cursor position is displayed by the expanded map.Type: GrantFiled: June 7, 1982Date of Patent: March 12, 1985Assignee: Nippondenso Co., Ltd.Inventors: Kunio Miura, Koshi Hasebe, Takashi Ono, Kazushi Akutsu, Shinji Ohyama, Kazuaki Minami

Patent number: 4502123Abstract: In a navigation system arranged to display a road map in accordance with road map information from a cassette tape, and the present location of a motor vehicle equipped with the navigation system, a cassette tape distinguishing circuit is provided to a cassette tape player which picks up the road map information from a predetermined cassette having a window at given portion of the cassette housing. A switching circuit is responsive to the cassette tape distinguishing circuit so that the output data of the cassette tape is processed to display a given map only when a cassette carrying road map information is loaded in the cassette tape player. In the case a normal cassette carrying audio signals, such as music, is loaded the picked up audio signal is transmitted to an amplifier so that sound reproduction is effected. Thus, a single cassette player can be used in common as both a part of the navigation system and a part of a sound reproduction system.Type: GrantFiled: July 6, 1982Date of Patent: February 26, 1985Assignee: Nippondenso Co., Ltd.Inventors: Kazuaki Minami, Shinzo Totani, Kunio Miura, Kazushi Akutsu, Shinji Ohyama
