Title: Closed speaker system
Inventor: SASAKI MASAAKI
IPC: H04R1/06
Filed: 1987-02-23
Abstract: PURPOSE:To effectively use the capacity of a speaker cabinet by connecting a speaker unit for tweeter to a speaker unit for woofer through the space between a closed projecting bank, which is pressed against a closed bush provided on the outside surface of a front plate of the speaker cabinet, and the closed bush. CONSTITUTION:A projecting bank 6 is provided on the inside face of a front panel 2 to cover the attaching position of a speaker unit 4 for woofer. The front end of the projecting bank 6 is pressed a closed bush 7, which is provided on the front of against a speaker cabinet 1 and consists of an elastic body, to attach the speaker unit 4 for woofer into the speaker cabinet 1 in a closed structure. In this case, the front panel 2 is attached to the front of the speaker cabinet 1 with wood screws 3 to press the front end of the projecting bank 6 against the closed bush 7. Consequently, the extent of projection of the speaker unit for woofer into the cabinet is very small and the capacity of the speaker cabinet is effectively used.

Title: Control method for tracking error detecting optical system of optical head
Inventor: MATSUI TSUTOMU
IPC: G11B7/09
Filed: 1987-02-23
Abstract: PURPOSE:To reduce the influence of the stray light for a recording/reproducing type optical head by obtaining the ground level of a tracking error detecting optical sensor in a state where the stray light exists. CONSTITUTION:The position of a tracking error detecting optical sensor 5 is controlled in a state where only the stray light caused by the going light produced by a beam splitter 2 is made incident on the sensor 5. Then, the optical axis of an objective lens 3 is controlled through the control of the entire shift of an objective lens actuator 10 in a state where the light returned from a disk is made incident on the sensor 5. As a result, the offset of the tracking error signal is reduced against to the stray light produced by the splitter 2. Thus, it is possible to ensure the tracking control with higher sureness even in a recording state of a recording/reproducing type optical disk device.

Title: Smut recovering facility in stack
Inventor: SHIMADA ISAMU
IPC: F23J3/02
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To easily recover smut by preventing scattering public nuisance of the smut in the case of internally cleaning a stack. SOLUTION: A blower 5 is driven to suck the smut together with the air from the stack 1 and to inject it from an exhaust hole 8 into water tank 10. Thus, the smut is deposited at a bottom of the tank 10, and further recovered via a recovery tube 15. The water contaminated with the smut is fed from the tank 10 into a sub-water tank 17. In the tank 17, the smut is precipitated to purify the water in the tank 17. The purified water is returned from the tank 17 into the tank 10, and hence contaminating degree of the water in the tank 10 can be reduced.

Title: Manufacture of precision casting
Inventor: SAKURABAYASHI NORIO
IPC: B22D29/00
Filed: 1985-02-28
Abstract: PURPOSE:To obtain a casting of complex shape hard to work and having high accuracy and favorable surface properties by breaking a casting mold to take out a casting, treating the casting with a molten alkali and finish-washing it with a washing soln. contg. a specified surfactant. CONSTITUTION:Molten metal is charged into a casting mold and solidified, and the mold is broken to take out a casting. This casting is treated with a molten alkali and finish-washed with a washing soln. prepd. by adding a fixed amount of a fluorine-contg. surfactant having perfluoroalkyl groups to water or an acidic soln. such as hydrochloric acid. Since the surfactant is com patible with the water or acid base and reduces the surface tension of the acid, it improves the wettability and can perfectly treat the remaining alkali hydroxide. Accordingly, precision castings having extremely superior surface properties can be manufactured in large quantities.

Title: Dimension measuring and apparatus therefor
Inventor: MIYAGI KOICHIRO
IPC: G01B11/02
Filed: 1986-02-25
Abstract: PURPOSE:To enable optical dimension measurement available for polarization of a high-speed beam of light, by applying liquid transmitting medium to a supersonic wave light modulator and making a supersonic wave signal transmitted through the modulator a sine-wave signal amplitude-modulated by rectangular pulses of fine widths. CONSTITUTION:A beam of light emitted from a laser light source 1is enlarged by beam enlarging lenses 2, 3, and the beam enters into a light admitting window 6 of a supersonic wave light modulator 5. Then, when a light flux incident on a soupersonic wave transmitting medium 8 in the modulator 5, a supersonic wave 14 is irradiated from the direction perpendicular to the direction of light propagation, a phase difference is created on the wave surface of the light flux. Further, a sine-wave amplitude-modulated signal by rectangular pulses is added to the modulator 5 from a burst generating apparatus 19. When the light flux thus phase-modulated is converged by a convergent lens 11, a diffraction image is obtained corresponding to a condition of the phase modulation. After installing a specified filter 12 in the focal plane, the beam of light passed through this is converted photoelectrically 13. A specimen 15 can be located anywhere in the hatched are and width of the beam of light can be reduced to a fine dimension and thus, resolving capacity at the time of measurement can be improved.

Title: Electrifying transfer system
Inventor: AKUTSU HIDEKAZU
IPC: B41J2/325
Filed: 1982-03-15
Abstract: PURPOSE:To effectively perform the transfer of clear-cut pictures by a method in which a recording electrode is pressingly contacted with an ink supporting layer, and a signal corresponding to recording information is applied to the electrode. CONSTITUTION:When applying recording signals of pulse form to a solenoid 5, a recording head 4 is pushed down and electrodes 4a and 4b are pressingly contacted with the back of an ink supporter 2. At the same time, a voltage is applied between a recording needle electrode 4a selected according to recording information and a return electrode 4b, but since the pressed portion of the ink supporter 2 is more greatly reduced in electric resistance than in the other portion, electric current from the electrode 4a is concentrated right below the electrode 4a where the electric resistance becomes lowest toward the conductive ink layer 3, and the current is diffused in every direction from there and returns to the return electrode 4b. Thus, right below the electrode 4a, Joule heat proportional to two power of the electric resistance and density of the ink supporter 2 is generated to melt the ink in the portion, and the melted ink is impregnated into a recording paper P.

IPC: G01L27/00
Filed: 1990-02-21
Abstract: PURPOSE:To output an air pressure signal with high accuracy by inputting the output of a 1st pressure sensor and the output of a 2nd pressure sensor to a maximum value selector and inputting the output which is larger between the outputs of the 1st and 2nd pressure sensors to a comparison part. CONSTITUTION:Set air pressure is set by a setting commanding and control part 9 and a voltage corresponding to the set value is generated by a set voltage generation part 1 and applied to the + input terminal of the voltage comparison part 2. The output of the comparison part 2 is applied to an electricity-air transducer 3, which outputs air pressure corresponding to the set value. This output air pressure is inputted to a pressure display part 4 and inputted to a low pressure sensor 10 and high pressure sensor 11 through a solenoid valve 5. The outputs of the sensors 10 and 11 are supplied to a signal selector 12, which selects and applies one of them to the - input terminal of the comparison part 2. The selector 12 selects and outputs the maximum value of the input signal value. Thus, the sensors 10 and 11 are used to generate a little variation in the set voltage even when the low pressure sensor is switched to the high pressure sensor, thereby obtaining the high accuracy.
