Abstract: A lower electrode and an adhesive layer made of an insulator are formed on a back surface on the ion implantation layer side of a piezoelectric single crystal substrate. A supporting substrate in which sacrificial layers made of a conductive material have been formed is bonded to the surface of the adhesive layer. By heating the composite body including the piezoelectric single crystal substrate, the lower electrode, the adhesive layer, and the supporting substrate, a layer of the piezoelectric single crystal substrate is detached to form a piezoelectric thin film. A liquid polarizing upper electrode is formed on a detaching interface of the piezoelectric thin film. A pulsed electric field is applied using the polarizing upper electrode and the sacrificial layers as counter electrodes. Consequently, the piezoelectric thin film is polarized.

Abstract: A method for producing a piezoelectric composite substrate having a single-crystal thin film of a piezoelectric material includes an ion-implantation step and a separation step. In the ion-implantation step, He+ ions are implanted into the single-crystal base made of the piezoelectric material to form localized microcavities in a separation layer located inside the single-crystal base and apart from a surface of the single-crystal base. In the separation step, the microcavities formed in the ion-implantation step are subjected to thermal stress to divide the separation layer of the piezoelectric single-crystal base, thereby detaching the single-crystal thin film.

Abstract: In a method for manufacturing an electronic device, an ion implantation layer is formed at a desired depth from one principal surface of a piezoelectric single crystal substrate by implanting hydrogen ions into the piezoelectric single crystal substrate under desired conditions. The piezoelectric single crystal substrate in which the ion implantation layer has been formed is bonded to a supporting substrate, and a piezoelectric thin film is then formed by the application of heat using the ion implantation layer as a detaching interface. This heated detachment is performed at a reduced pressure less than atmospheric pressure and at a heating temperature determined in accordance with the reduced pressure.

Abstract: In the present invention, a conditional probability distribution function of received signal which is conditioned with a received signal amplitude (a), a pseudo range (p) and a navigation bit (bm) which are unknown parameters is acquired from a GPS signal sample S2 on the basis of a condition defined by a working hypothesis set in a working hypothesis setting part WH(i) and then the conditional probability distribution function (P(Rm|a, p, bm)) is marginalized with respect to the pseudo range (p) to acquire a marginal posterior probability distribution function (P(p|Rm, a)) in a step ST11. Finally acquired is a pseudo range dependent function in proportion to the marginal posterior probability distribution function (P(p|Rm, a)). Then, in a step ST12, a value of pseudo range (p) which gives the maximum value of pseudo range dependent function is determined as an estimated pseudo range.
