Title: Rotary magnetic head device
Inventor: KAWASAKI OSAMU
IPC: G11B5/592
Filed: 1982-07-20
Abstract: PURPOSE:To set a magnetic head under the optimum tracking state, by attaching a magnetic head to the tip part of a circular flexural oscillator formed by bonding two piezoelectric oscillators to a circular metallic plate and then attaching the oscillator to a rotary cylinder. CONSTITUTION:A flexural oscillator is formed by bonding two piezoelectric oscillators 1 polarized in the thickness direction with electrodes attached on each main surface to a metallic plate 2. The tip part of the flexural oscillator has only a metallic plate 3, and the plate 3 has the flexural rigidity that is extremely smaller than other areas. Then the magnetic head 3 is attached to the metallic part at the tip of the flexural oscillator. The flexural oscillator is attached to a rotary cylinder 5 through an attachment part 4. When an electric field is applied to the flexural oscillator, the tip part where the magnetic head is attached has a displacement in response to the scale of the applied electric field. Thus it is possible to obtain the optimum tracking state by the control of the applied electric field. It is possible to have the larger length of a flexural oscillator than that of a rectangular flexural oscillator. Thus a larger displacement is ensured. At the same time, the flexural rigidity is reduced at the tip of the flexural oscillator to obtain a large displacement as well.

Abstract: PURPOSE: To make the sum total value of memory storage contents not depend upon a memory unwritten area and efficiently collate the memory storage contents by ORing bit arrays in units of a specific number of bits and calculating the sum total value, and collating the sum total value with a previously found inverted sum total value. CONSTITUTION: A CPU 3 reads data as the storage contents of a ROM 1, byte by byte, and inverts and ORs them in order to calculate the sum total value. This value is compared and collated with the inverted sum total value 4 of the storage contents of the ROM 1 which is previously found to check whether they match each other, and it is confirmed that the storage contents of the ROM 1 are wrong when they do not match each other and correct when they match each other. Therefore, a data processor with high reliability can be actualized. At this time, the logic of bits in the ROM unwritten part is inverted irrelevantly to whether or not the range of the storage contents read out of the ROM 1 includes the ROM unwritten area to eliminate the need for the sum total value.

Title: Optical microphone
Inventor: TANIGUCHI YOSHIHARU
IPC: H04R23/00
Filed: 1998-05-11
Abstract: PROBLEM TO BE SOLVED: To produce linear output and to attain reception with high sensitivity by setting the total area of an radiating outlet window and a photodetecting inlet window at a specific rate against a membrane area and also including the concave multi-dimensional function curves more than a specific dimension in a vertical section shape of an electromagnetic wave light guiding part. SOLUTION: The total area of an outlet window 8 and an inlet window 7 is set at 5% or less of a membrane area. The wide spaces are secured at the places near a membrane 5 and both windows 8 and 7 to reduce the harmful effects of the negative pressure against the vibrations of the membrane 5 if a light guiding part 9 includes the concave curve parts of 1.2 dimensions or more. As the outside of the part 9 consists of a continuous curve, the gas existing near the part 9 smoothly moves and functions to improve the linearity of the signal output. When the angle is set as α between the curve tangent and a substrate, the light emitted vertically from a light emitting element 1 is reflected by the curve and reaches the window 8 at an incident angle of (180-2d).  Thus, the light is emitted to the outside through the window 8 as long as the said incident angle is set smaller than the critical angle of a light shielding material.
