Title: Dynamic tracking method for magnetic disc recording and reproducing device
Inventor: OOTA YOSHITAKA
IPC: G11B21/10
Filed: 1981-09-11
Abstract: PURPOSE:To make a magnetic head follow a track, even if shift exists between the track and the magnetic head due to the eccentricity of a disc, by displacing the position of the magnetic head by an amount represented by the amount of eccentricity of the magnetic disc. CONSTITUTION:A track D recorded with a radius gamma0 in using a point A as a center is turned around a point B, and reproduction is performed with a magnetic head fixed to a point C apart from the point B by the distance gamma0. Then, a distance delta between the points A and B is the eccentricity and a distance between the point C and a point E represents a track shift (x). In this case, the track shift (x) is a value obtd. by subtracting a distance BE from the distance  gamma0 and is expressed as the product of a distance delta and costheta. Since the angle theta  is originated from the revolution of a magnetic disc rotating motor, the magnetic head can accurately follow the track by providing the displacement of deltacostheta to the head in synchronizing with the motor.

Title: Oxide superconductive element and manufacture thereof
Inventor: TSURU KOJI
IPC: H01L39/24
Filed: 1990-05-31
Abstract: PURPOSE:To obtain a product superconductive element relatively easily with high yield by diffusing a nonsuperconductor into a thin film of oxide superconductor by heat treatment and by controlling the ratio of oxide superconductor to nonsuperconductor. CONSTITUTION:A substrate 1 is overlaid with a deposit of thin film 3 in a strip form using sputter deposition for example. Further, a thin film 2 of oxide superconductor is vapor-deposited thereon. This laminated film is subjected to a heat treatment of 900 deg.CX1hr in an oxygen atmosphere for example. Such a laminated structure allows nonsuperconductor to diffuse from the thin film 3 of nonsuperconductor into the thin film 2 of superconductor by heat treatment, thereby reducing superconductive regions to form week junctions. Since the ratio of superconductor regions to nonsuperconductor regions can be controlled by controlling heat treatment conditions only, an oxide superconductor element can easily be manufactured with high yield.

Title: Sound pressure detector
Inventor: TODA KOJI
IPC: G01H3/00
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To obtain a small and lightweight sound pressure detector having high detection sensitivity and excellent in high speed response which can be driven with low power consumption by detecting a sound pressure propagating through a gas and representing the detected sound pressure as an electric signal. SOLUTION: When an input electric signal is applied to an input blind-like electrode 2, a leakage elastic wave is excited in a piezoelectric substrate 1. The leakage elastic wave propagates, as a longitudinal wave, through a liquid in a liquid chamber 4 before being reflected on an elastic film 7. The reflected longitudinal wave is detected, as a delay electric signal, by a blind-like electrode 3. When the elastic film 7 senses an external sound pressure, the elastic film 7 vibrates mechanically to cause variation of the delay electric signal. Variation of the delay electric signal is detected by a signal analyzing means 8 and displayed on a display screen 9.
