Title: Magnetic recorder
Inventor: MATSUYAMA HIDEO
IPC: G11B5/65
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording system without needing leaked magnetic fields from a medium by using magnetic material whose magnetic strain is large as the medium and adding a means detecting the strain of the medium newly. SOLUTION: Induction type ring heads having the same shapes are used as a magnetic head and a magnetic head for recording. One or plural piezo elements 6 is or are attached on the back of a substrate 5 so as to efficiently detect sound waves from a medium. Moreover, TbFe2 , Ni alloy or the like whose magnetic strains are large are used as magnetic material for a medium 4. A magnetic disk consisting of the medium 4 and the substrate 5 performs a revolving motion and a slider moves over the medium 4. Here, the distance among the magnetic head 1 and the magnetic head 2 fixed to the slider an the medium 4 is controlled so as to become a constant value of not larger than several hundred nanometers. Since a rewriting operation is accompanied at the time of reproduction, the destruction of bit information due to a thermomagnetic excess effect or the like is prevented in written bits.

Abstract: PURPOSE:To contrive the prevention of the generation of a break, a crack and the like in the outer peripheral part of a wafer by a method wherein the diameter of a first wafer is left without being changed and at the same time, the unbonded outer peripheral part, at which the first wafer and a second wafer oppose to each other pinching a void between them, of the wafer is removed. CONSTITUTION:A bonded semiconductor substrate (a bonded wafer) 14 is formed by a method wherein the fellow mirror-polished main surfaces of first and second semiconductor substrates (first and second wafers) 11 and 12 performed a bevel work 16 on their sidewalls are closely adhered to each other, are heat-treated and are integrally formed, and a joined semiconductor substrate 15 is formed by a method wherein the fellow main surfaces, which are mirror- polished and on the main surface of a first semiconductor substrate 11a on at least one side of which an oxide film 13 is applied, of the first substrate 11a and a second semiconductor substrate 12, which are performed a bevel work 16 on their sidewalls, are closely adhered to each other, are heat-treated and are integrally formed. The diameter of the substrate 11 of the substrate 14 is left without being changed and at the same time, the sidewall of the substrate 14 is ground so that an unbonded outer peripheral part, at which the substrates 11 and 12 oppose to each other pinching a void between them, does not exist. In such a way, the unbonded outer peripheral part, that is, the outer peripheral part, at which the first and second wafers oppose to each other pinching a void between them, is removed. Thereby, a supply of the bonded wafer, in which a break, a crack and the like are not generated in its outer peripheral part, becomes possible.

Title: Detection circuit device for ultrasonic propagation time
Inventor: KOUNO MASARU
IPC: G01B17/02
Filed: 1978-08-09
Abstract: PURPOSE:To detect accurately propagation time without reference to attenuation of an ultrasonic wave in a measurement medium by detecting the arrival of the ultrasonic wave to a receiving transducer at the point in time when the output signal crosses OV. CONSTITUTION:When an ultrasonic wave is attenuated, its amplitude attenuates, but it is invariably constant regardless of the attenuation at cycles where waves (f1), (f2), (f3),... appear. In other words, the 3rd wave (f3), for example, crosses OV in the plus direction invariably at point P5. For the purpose, mistrigger detection circuit 500 is provided so as to detect a point in time when output signal P crosses OV, e.g. point P5, which is regarded as the arrival point of the ultrasonic wave at the receiving transducer, so that without reference to the attenuation of the ultrasonic wave, the propagation time can accurately be detected according to the arrival of the wave.

Filed: 1982-06-08
Abstract: PURPOSE:To increase a radially restoring force by providing both permanent magnets and a disc which is made of magnetic material under the lower face of a bearing seat and at a position where a fixed member is opposed thereto. CONSTITUTION:A bearing seat disc 9 which is made of magnetic material and a casing disc 10 are firmly fit to the lower face of a bearing seats 3 and to a part where a casing 5 is opposed thereto. A plurality of ring-like projections 9a and 10a are integrally formed on the lower face of the bearing seat disc 9 and the upper face of the casing disc 10 around the center of permanent magnets 4 and 6, respectively. In this construction, magnetic flux psi from the permanent magnets 4 and 6 then flows as shown by the two-dotted line. Since magnetic resistance is reduced between the mutually opposed ring-like projections 9a and 10, the density of the magnetic flux psi becomes high so that the electromagnetic fringe effect may be evidently exhibited. The fringe effect aids the encouragement to the radial recovering force.

Filed: 1984-05-18
Abstract: PURPOSE:To decrease field noises by inserting a delay circuit to one of both control signals which control P and NMOS transistors to secure a time difference. CONSTITUTION:A delay circuit A is provided to a signal C' of both signals C and C' which control P and NMOS transistors TRM1 and 2.

Abstract: PROBLEM TO BE SOLVED: To conduct height adjustment through very simple operation by bringing the inside wall of a button penetration hole into contact with a shaft by means of energizing force toward a button part, and retaining the shaft so as not to move. SOLUTION: A button part 50 is energized in the outward direction of a device 10 by the energizing force of a coil spring 52, and a shaft 20 is retained by the inside wall of a button penetration hole 53. The device 10 is always kept at a constant height and angle. In changing the height of the device 10, the button part 50 is pressed. The coil spring 52 is compressed, so that the button 50 moves to the inward direction of the device 10 in button engaging part. When the button part 50 moves, the button penetration hole 53 of long hole shape also moves in the inward direction of the device 10, so that fixation of the shaft 20 is released. After moving the shaft 20 up and down and setting it at a desired height, the button 50 is released. It is thus possible to retain the shaft 20 and fixed it at a setting position again.
