Patent number: 7360456Abstract: A sensor strain causer can be made into a simple shape, and the attachment work for strain gauges is made easy. In a multiaxial sensor 1 for measuring one or more of multiaxial force, moment, acceleration, and angular acceleration, externally applied, a plurality of strain gauges R11 to R48 disposed on one plane are provided. Thereby, because the time for the attachment work for the strain gauges R11 to R48 can be shortened, the mass productivity can be improved and the cost can be reduced.Type: GrantFiled: June 16, 2004Date of Patent: April 22, 2008Assignee: Nitta CorporationInventor: Hideo Morimoto

Publication number: 20080018347Abstract: In a capacitance type sensor, capacitive elements are formed between a displacement electrode 104 and capacitance electrodes E1 and E2. When an external force is applied, the displacement electrode 104 is displaced to come into contact with a switch electrode E3 or E4 kept at a ground potential. The displacement electrode 104 is further displaced with being in contact with the switch electrode E3 or E4. When the displacement of the displacement electrode 104 changes the distances from the capacitance electrodes E1 and E2, the capacitance values of the capacitive elements change. Based on the changes, the force is detected.Type: ApplicationFiled: July 5, 2007Publication date: January 24, 2008Applicant: NITTA CORPORATIONInventor: Hideo Morimoto

In a strain gauge type sensor 1 for measuring at least one of multiaxial force, moment, acceleration, and angular acceleration, externally applied, diaphragms 15 and 16 different in thickness are formed at inner and outer edges of a substantially disk-shaped interconnecting portion 13 interconnecting a vicinity of an upper end of a force receiving portion 11 and a fixed portion 12 disposed around the force receiving portion 11. The thicknesses of the diaphragms 15 and 16 are determined such that strains at intersections of a straight line extending through an origin O with the diaphragms 15 and 16 are equal to each other. Strain gauges are disposed at the intersections of the straight line extending through the origin O with the diaphragms 15 and 16.Type: ApplicationFiled: June 21, 2004Publication date: April 26, 2007Applicant: NITTA CORPORATIONInventor: Hideo Morimoto

Patent number: 7119552Abstract: Capacitance element electrodes (E1 to E5) and a grounded reference electrode (E0) are formed on a substrate (20). A displacement electrode (40) that is Z-axially displaced in accordance with a Z-axial movement of a detective member (30) externally operated, is disposed so as to be opposed to the above electrodes (E0 to E5). The displacement electrode (40) cooperates with the reference electrode (E0) and the capacitance element electrodes (E1 to E5) to form capacitance elements (C0 to C5), respectively. Each of the capacitance elements (C1 to C5) is connected to the capacitance element (C0) in series in relation to an externally input signal. Changes in the capacitance values of the capacitance elements (C1 to C5) when the detective member (30) is moved, is detected by a signal processing circuit having hysteretic characteristics. Thereby, the displacement of the detective member (30) is detected.Type: GrantFiled: January 6, 2003Date of Patent: October 10, 2006Assignee: Nitta CorporationInventors: Hideo Morimoto, Tomohiro Agaya

Patent number: 7064561Abstract: In a resistance type sensor of the present invention, a sensor unit having variable contact resistances and a wakeup switch formed in two layers is produced by folding a FPC forming thereon pressure-sensitive resistive inks, a displacement electrode connected to ground, and a displacement electrode held at a power-supply voltage Vcc. Accordingly, whenever operation is applied to an operating button, the displacement electrode and the displacement electrode are reliably contacted with each other, first, and, then, resistance values of the variable contact resistances are changed while the displacement electrodes are kept in their contacted state. This enables the operation applied to the operating button to be detected reliably.Type: GrantFiled: July 3, 2003Date of Patent: June 20, 2006Assignee: Nitta CorporationInventor: Hideo Morimoto

Patent number: 6958614Abstract: In a capacitance type sensor of the present invention, a capacitance element is constituted between a displacement electrode and a capacitance element electrode. A return-switch movable electrode is arranged above and spaced from the displacement electrode, to be placed in contact with the displaying electrode due to a displacement of a direction button. When the direction button is operated, the return-switch movable electrode is first displaced into contact with the displacement electrode. Then, the both make a displacement while keeping a contact state. When the displacement electrode is displaced to change the spacing to the capacitance element electrode, changed is the capacitance value of the capacitance element. Based on this change, a force is recognized. Herein, in the course of a transit from a state the displacement electrode and the return-switch electrode are not in contact to a state of their contact, the output signal varies necessarily beyond a threshold voltage.Type: GrantFiled: May 28, 2003Date of Patent: October 25, 2005Assignee: Nitta CorporationInventor: Hideo Morimoto

Patent number: 6933732Abstract: A movable switch electrode (E21) which is contactable with a capacitance element electrode (E1) formed on a substrate (20) and is spaced apart from a fixed switch electrode (E11) formed in an interior of the capacitance element electrode (E1) and having a domed form to cover the fixed switch electrode (E11) is set in place. When a detective member (30) is operated and a force applied from a displacement electrode (40) to the movable switch electrode (E21) reaches a specified value, the movable switch electrode (E21) is elastically deformed and depressed drastically with buckling at the nearly top portion thereof and is brought into contact with the fixed switch electrode (E11). This brings the switch into the ON-state. At this time, an operator is given a pronounced click feeling.Type: GrantFiled: May 17, 2001Date of Patent: August 23, 2005Assignee: Nitta CorporationInventor: Hideo Morimoto
