摘要:
A semiconductor pressure sensor (720) includes a thin film piezoelectric element (701) which applies strain to a portion of a semiconductor substrate that corresponds to a thin region (402). The thin film piezoelectric element (701) is formed at a distance away from diffusion resistors (406, 408, 410, and 412) functioning as strain gauges and is extended to the proximity of a bonding pad (716A) connected to an upper electrode layer of the thin film piezoelectric element and a bonding pad (716F) connected to a lower electrode thereof. The diffusion resistors (406, 408, 410, and 412) constitute a bridge circuit by metal wiring (722) and diffusion wiring (724). During self-diagnosis, a prescribed voltage is applied to a thin film piezoelectric element (701). If the output difference of the bridge circuit between before and after the voltage application falls outside a prescribed range, it is determined that a breakage occurs in the semiconductor pressure sensor (720).

In an angular velocity sensor, an upper electrode of a first piezoelectric element and a lower electrode of a second piezoelectric element are connected to an input terminal of a first Q/V conversion circuit, and a lower electrode of the first piezoelectric element and an upper electrode of the second piezoelectric element are connected to an input terminal of a second Q/V conversion circuit. Thus, vibration noise components of the quantities of charge generated at the first and second piezoelectric elements are cancelled out, and Coriolis components of the quantities of charge generated at the first and second piezoelectric elements are added, whereby only the Coriolis components are extracted.

A magnetic sensor includes a magneto-electric transducer, a switch circuit, an amplifier circuit, a subtractor circuit, and a selector circuit. The subtractor circuit performs a first subtraction process of generating a first subtraction voltage by subtracting an amplification voltage obtained under an immediately prior first bias state from an amplification voltage obtained under a second bias state and a second subtraction process of generating a second subtraction voltage by subtracting an amplification voltage obtained under an immediately prior second bias state from an amplification voltage obtained under a first bias state in a serial and parallel manner. The selector circuit alternately selects the first subtraction voltage and the second subtraction voltage to output a select voltage.
摘要:
It is an object of the invention to provide a composition with an excellent action of inhibiting vascularization, as prepared by a simple method suitable for actual production from an inexpensive, relatively readily available material without any problematic safety profile at an industrial scale without any complicated purification step. The composition is a composition for inhibiting vascularization, which contains a barley-derived ingredient selected from the group consisting of an unpolished barley ethyl alcohol extract fraction, an unpolished barley alkali extract fraction and fermented barley (preferably, a residual solution from the distillation of barley distilled spirits) as the active component with an action of inhibiting vascularization. The composition for inhibiting vascularization is a composition for therapeutically treating or preventing diseases which vascularization should be inhibited, specifically diseases with an etiology of abnormal vascularization in tumor or cancer, chronic inflammation or retinopathy. The composition is in a form selected from the group consisting of food additives, food materials, foods and drinks, pharmaceutical products under regulations by the Ministry of Health and Labor in Japan and quasi-pharmaceutical products under regulations by the Ministry of Health and Labor in Japan, and feeds.

A composition having effects of inhibiting the onset of alcoholic liver injury and healing it which comprises an unadsorbed fraction obtained by subjecting a barley shochu stillage obtained as the by-product in the production of shochu from barley to solid/liquid separation and then subjecting the liquid fraction thus obtained to a separation treatment by adsorption. The unadsorbed fraction contains plural peptides having an average chain length of from 3.0 to 5.0. These peptides are composed of from 24 to 38% of glutamic acid, from 4 to 20% of glycine, from 5 to 10% of aspartic acid, from 4 to 9% of proline and from 4 to 8% of serine, referring to the total amino acid content originating in these peptides as 100%. A food composition comprising the above unadsorbed fraction and having a favorable taste is also disclosed.
