Title: Optical axis display device
Inventor: AIUCHI SUSUMU
IPC: G02B21/06
Filed: 1977-12-23
Abstract: PURPOSE: To facilitate and ensure the optical axis adjustment of an illuminating light by measuring the light quantity distribution of a focused image of a cross pattern groove by a microscope thereby to display te center coordinates of the image intensity distribution.  
     CONSTITUTION: The focused light of such a cross pattern by a mocroscope as is irradiated from a light source 1 having its brightness uniformly distributed by a light quide has its displacement detected by a displacement meter 18 so that it is received by a photoelectric element 17 through a slit 15 which is synchronously reciprocated to a preset extent. Likewise, if the slit 15 is turned by 90 degrees about an optical axis, the image light of the pattern 12 in the two perpendicular directions is scanned. The detected signals corresponding to the irregularity in the brightness of the element 17 are subjected to A/D conversion and stored in a memory 26 so that the are processed by a calculation control circuit 25, which has its plural threshold values preset, in accordance with the detected values of the element 17 upon the illumination of a mirror surface with an identical light source. Then, the coordinates of the center locus MN of an intensity distribution of the image of the pattern 12 are displyed in a monitor 28. As a result, if the monitor 28 is observed to position the locus MN upright, the axis of the illuminating light can be adusted easily and reliably. Like results can be obtained if the slit is replaced by an image sensor.

Title: Organic electrolyte battery using highly concentrated mixed solute
Inventor: YADA SHIZUKUNI
IPC: H01M10/0569
Filed: 1987-06-23
Abstract: PURPOSE:To make a battery compact by using a highly concentrated mixed solute electrolyte obtained by dissolving two or more lithium salts in an aprotic solvent. CONSTITUTION:A solution obtained by dissolving two or more lithium salts in an aprotic solvent so as to have a concentration of 1.5-4M.

Title: Spring-up device for outboard motor
Inventor: INOUE SEIJI
IPC: B63H20/08
Filed: 1982-09-07
Abstract: PURPOSE:To obtain a smooth tilt-up by providing a means to detect a helm angle of a propelling unit so that tilt-up operation by a tilt-up device can be performed only when the helm angle indicates an almost neutral position. CONSTITUTION:When a tilt switch 48 is closed toward a up-relay 46 side, a tilt motor 45 makes tilt-up operation via a relay in order to tilt-up a propelling unit. On the other hand, when the switch 48 is closed toward a down-relay 47 side, the motor 45 tilts down the propelling unit via the relay 47. At that time, since a detector 35 turns ON only when the helm angles of the propelling unit and a steering lever indicate an almost neutral position, tilt-up or tilt-down operation is not allowed when helm angle indication is not almost neutral. With this contrivance such accident as the propelling unit and a crank bracket interfere to damage each other, which occurs during tilt-up operation with the large helm angle, can be prevented.

Title: Low nox burner for heating furnace
Inventor: SHIRAISHI NORIHISA
IPC: F23C99/00
Filed: 1985-07-16
Abstract: PURPOSE:To enable ensurance of a low NOX level, by a method wherein a part of combustion gas is recirculated through absorption action of a primary air to produce slow low combustion and flame characteristics are regulated by a primary air ratio. CONSTITUTION:Fuel gas is discharged in an annular shape of a thin film manner through an annular nozzle 10, with air regulating valves 5 and 12 opened, when a primary air flowing from a swirl blade 6 is collided with the inner surface of a fuel gas flow for ignition to yield combustion. Meanwhile, a secondary air is injected from a secondary air chamber 15 through secondary air nozzles 19 and 20 and collided with the outer surface of a combustion gas flow to yield combustion. A part of combustion gas enters the interior of a mixing chamber 16 through a return hole 21, and is mixed with fuel gas through a recirculating port 23 for injection to the outer surface to yield recirculation. Thus, slow low-temperature combustion is created, and the generation of NOX is prevented along with an increase in the outer surface area of a combustion flame. Control of air regulating valves 4 and 12 causes a change in a primary air ratio and regulation of flame characteristics, and this enables effective maintenance of NOX level.

Title: Measuring method for thickness
Inventor: KOUNO AKIO
IPC: G01B15/02
Filed: 1978-12-15
Abstract: PURPOSE: To measure the thickness without contacting with the measured object, by measuring the extent of movement detected with the scattered beams through the movement of the detector in the direction of the thickness in which the scattered  beams from the measured object are received through the emission of radiant rays  from the beam source.  
     CONSTITUTION: The radiant ray source 2 is located on the measured object 1, and radiant rays A are emitted to the measured object 1 from the opening 4 of the shielded object 3. The radiant ray detector 5 is enclosed with the shield material 6 so that the scattered beams B can be incident from one direction only, the detection  of scattered beams is made while moving the detector 5 in parallel with the direction of the thickness to measure the extent of movement P in which the scattered beams can be detected. Since the extent of movement P which can detect the scattered beams B and the thickness x are in geometrical relation according to the Compton effect, the thickness x can directly be known from the extent P. With this thickness measuring method, simple measurement is enabled without contacting the measuring unit on the measured object.

IPC: H02K35/02
Filed: 1985-07-15
Abstract: PURPOSE:To absorb the oscillation of an oscillating unit with the oscillation of a magnet and to effectively obtain the reciprocating motion of the magnet for electrical energy, by arranging a magnet supported in spring system, in coils fixed on the oscillating unit. CONSTITUTION:A bobbin 4 fixed on an oscillating unit 1 is arranged to be positioned on the periphery of a magnet 3, and coils 5 are arranged on the periphery of the bobbin 4. The system organized with a spring 2 and the magnet 3 is previously contrived to have the natural oscillation frequency almost equal to the oscillation frequency of the oscillating unit 1. When the oscillating unit 1 oscillates, the oscillation of the oscillating unit 1 is absorbed by the spring 2 and the magnet 3.

Title: Heat exchanger and production of high purity powder and grain
Inventor: KUNII DAIZO
IPC: F28D11/04
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To perform heat exchange of high purity material to be processed efficiently by passing fluid through the air gap between an outer tube and a tubular pipe and exchanging with the material to be processed. SOLUTION: A material being subjected to heat exchange is fed from one end of a tubular pipe 1. The material rolls through rotation of the tubular pipe 1 to move easily in the direction of the other end from the supply end. The tubular pipe 1 is secured at two or a plurality of supporting parts 2. An outer tube 3 is arranged to surround the tubular pipe 1 and cooling gas flows through a gap defined by the outer circumference of the tubular pipe 1 and the outer tube 3 made of a heat resistant heat insulating material. The outer tube 3 is constructed independently from the tubular pipe 1. Since a driving force for turning the tubular pipe 1 is not transmitted externally through the outer tube 3 surrounding the tubular pipe 1 through a gap passing a fluid for heat exchange, interlocked rotation of the outer tube 3 and the tubular pipe 1 is not required.

Filed: 1995-06-22
Abstract: PURPOSE: To improve the physical S/N of an input signal and to improve the clarity of the signal considering a human sensation by using a frequency analysis method the more lowered in frequency resolution for higher frequency band. CONSTITUTION: An input voice is inputted to a frequency analysis part 1, and frequency analysis are performed at both of the time when a voice is included and the time when the voice rests (when only a noise). As the frequency analysis method, e.g. a wavelet conversion is adopted. A voice emphasis is performed based on the analysis result obtained by the frequency analysis part 1. Since the frequency resolution is more lowered in the high frequency band so as to match with the human sensation by the wavelet conversion method and a geometric frequency analysis method, etc., and on the other hand, the analysis method more improved in space resolution or time resolution in the high frequency band is used, not only the physical S/N, but also the clarity in the human sensation such as monosyllabic clarity in the case of the voice emphasis is improved.
