  • Publication number: 20240071344
    Abstract: A musical instrument includes a fixed member; a movable member displaceable in response to a playing operation of the musical instrument, the movable member being displaceable relative to the fixed member from a first state where the movable member is in an initial position to a second state where the movable member is displaced from the initial position; a detectable circuit including a magnetic or conductive body and disposed on the movable member; and a detector circuit including a coil disposed on the fixed member and configured to output a detection signal corresponding to a voltage that is dependent on a distance between the detectable circuit and the coil. A distance between the detectable circuit and the coil in the first state is smaller than a distance between the detectable circuit and the coil in the second state.

  • Publication number: 20180358257
    Abstract: A method of forming an integrated circuit includes forming at least one hard mask layer on a device layer of a silicon-on-Insulator (SOI) substrate. A patterned trench etch forms larger area and smaller area trenches through the hard mask layer, device layer and BOX layer. A dielectric liner is formed for lining the larger area and smaller area trenches. A sub-atmospheric pressure chemical vapor (SACVD) dielectric layer is deposited for filing the smaller area trenches and partially filling the larger area trenches. The larger area trenches are bottom etched through the SACVD layer to provide a through-substrate contact (TSC) to the handle portion. The SACVD layer is densified after bottom etching, the handle portion at a bottom of the larger area trenches is implanted to form a handle contact, and the larger area trenches are filled with an electrically conductive layer to form a top side ohmic contact.

  • Patent number: 9206894
    Abstract: One of two clutches etc. engaged concurrently with each other to establish a second speed, a third speed, or a fourth speed is determined in advance as an abnormal-time engagement element that is kept engaged when an abnormality occurs in which one different clutch or brake is engaged during concurrent engagement of the two clutches etc. The other of the two clutches etc. is determined in advance as an abnormal-time slipping element that is caused to slip when such an abnormality occurs. During concurrent engagement of the two clutches etc., a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time engagement element is set to be higher than a hydraulic pressure (target hydraulic pressure) to be supplied to the abnormal-time slipping element.
