Title: Measuring method for lattice constant of piezoelectric crystal
Inventor: TOMINAGA HIDEKI
IPC: G01N23/20
Filed: 1992-02-24
Abstract: PURPOSE:To prevent the accurate measurement of lattice constants from being hindered by coating the whole surface of a piezoelectric crystal, whose lattice constants are to be measured, with a conductive thin film. CONSTITUTION:A wafer 1 is made from electro-optical material used for optical devices, and the thickness thereof is d. A conductive thin film 2 is made from conductive material, whose surface, back face and whole side face are coated so as to form the thin film being t in thickness. Since lattice constants are obtained through the thin film 2 by means of X-radiation analysis, the thickness is not allowed to be so thick as to produce the crystal of the thin film. The material is to absorb little X-radiation as its characteristic. From the viewpoint of optical devices manufacturing, the material is required to disappear by oxidation, or to be removed by acid or alkali. Carbon is most suitable as the thin film, and gold, silver, or organic substance having conductivity are also available as the thin film. The thin film thickness stays normally in a range from several tens to several hundreds angstroms. The purpose of the thin film is to let charge escape, and the thin film is allowed to be studded as islets-like on the surface thereof.

Title: Plastering trowel
Inventor: NONAKA TAKEYOSHI
IPC: E04F21/16
Filed: 1990-02-16
Abstract: PURPOSE:To prevent peeling off of tiles from a concrete wall by mounting a vibration generating body on the upper surface of a plastering trowel plate in a removable state and making the joining force of a base mortar layer to the concrete wall stronger by vibrating the trowel plate. CONSTITUTION:A vibration generating body V is mounted on the upper surface of the plastering trowel 2 together with a permanent magnet 1. The body contains a vibrating motor 6, dry cells 7, and a switch 8 and the rotary shaft 6a of the motor 6 is eccentrically fitted with a weight 9. In order to make the surface of a base mortar layer applied to a concrete wall smooth, the trowel is used while the motor 6 is actuated. Because of the vibration of the trowel plate, the water contained in the mortar comes out and the affinity of the mortar layer to the surface layer section of the concrete wall is enhanced, resulting in an increase in the joining force of the mortar to the concrete wall. Therefore, peeling off of tiles from the concrete wall can be prevented.

Filed: 1992-01-29
Abstract: PURPOSE:To obtain a small-sized high efficiency encoder by weighting a bit distribution depending on the size of the signal of each block corresponding to the band to which the block is corresponded. CONSTITUTION:Adaptive bit assignment encoding means 16 to 18 perform bit assignment as a division ratio between the pattern part of fixed bit assignment preliminarily set for each subblock subdivided for time and frequency and the pattern part of bit assignment depending upon the size of the signal in each subblock, for the entire bits usable for the bit assignment. The adaptive bit assignment encoding means 16 and 18 perform the bit assignment for the bit depending upon the size of the signal in each subblock which is made based on the weighting corresponding to a frequency band to which the subblock is corresponded, by means of a weighting coefficient which is changed with the input signal. Thus, for the signal having plural solitary spectrum, the efficient bit assignment adaptive to a auditory sense can be easily realized.

IPC: H01L21/205
Filed: 1985-02-26
Abstract: PURPOSE:To enable to epitaxial-grow a silicon layer with high quality causing no slipping at all by a method wherein a silicon hydride gas is fed to a chamber to irradiate part of wafer with ultraviolet rays. CONSTITUTION:A wafer 41 is heated up to 850 deg.C and then while irradiating the overall surface of wafer 41 with laser beams (ultraviolet rays with wavelength shorter than 4,500Kt), H2 gas is fed to a chamber to etch the surface of wafer 41. Firstly SiH4 gas is fed to the chamber and then the laser beams are scanned on the specified region only of water 41 to epitaxial-grow a silicon layer 43 selectively. Secondly lowering the temperature down to 700 deg.C, O2 gas is fed to the chamber 11 and then silicon wafer 41 whereon the silicon layer 43 is not yet epitaxial-grown is irradiated with the laser beams to form oxide films 44. Through these procedures, any autodoping from the wafer 41 may be avoided since the silicon layer 43 may be epitaxial-grown selectively at the temperature lower than 900 deg.C on the silicon wafer 41.

Abstract: PURPOSE:To automatically measure dynamic distribution data on a gap with high accuracy by storing a frame memory with a brightness signal obtained by scanning interference fringes between two members in relative motion detected by a photoelectric converter, and performing arithmetic processing by a computer. CONSTITUTION:A recording medium 7 held on the rotary shaft of a driving motor 10 by a clamp 11 is driven by the driving motor 10 and put in relative motion with a simulation head 6.

This light is reflected by the reverse surface of the head 6 and the top surface of the medium 7 to become interference light because of the optical path difference, thereby forming an image on the photoelectric converter 9 through the mirror 4. Then the brightness signal on at least one line of interference fringes scanned by this converter 9 is stored in the frame memory 16 in time series and in picture element units. Then the computer 17 processes the distribution data on the gap according to the brightness signal which is read out of the memory 16.
