Title: Optical spectrum analyzer
Inventor: SONOBE YOJI
IPC: G01J3/26
Filed: 1989-03-31
Abstract: PURPOSE:To improve measuring accuracy of the intensity of light to a large extent in addition to accuracy in wavelength by adjusting the gain so that the intensity of light from a measuring photodetector which is changed to reference light agrees with the intensity of light from a calibrating photodetector. CONSTITUTION:The intensity of reference light (d) having a reference wavelength is detected with a calibrating photodetector 16. Then an optical switch 11 is switched, and the reference light (d) is split into a Fabry-Perot type spectroscope 1. The intensity of the split light is detected with a measuring photodetector 2. A gain-adjustment control means 15a which is provided in a data processing part 15 is adjusted so that the intensity of the light from the calibrating photodetector 16 agrees with the intensity of the split reference light (d). Thereafter, the optical switch 11 is switched so as to select light to be measured (a). The light to be measured is split in the Fabry-Perot type spectroscope 1. The light is converted into the optical intensity in the measuring photodetector 2. The gain is adjusted, and the intensity is automatically corrected to the correct optical intensity.

Title: Incandescent lamp
Inventor: TANAKA SUMIKO
IPC: H01K1/14
Filed: 1990-03-30
Abstract: PURPOSE:To enhance efficiency of an incandescent lamp by making the cross section of a bulb roughly elliptical, and disposing the end portion of a filament near the first and second foci of the ellipse. CONSTITUTION:The cross section of a bulb 1 in the direction perpendicular to a bulb axis O-O is roughly elliptical and a filament 5 is provided along the major axis of the ellipse and the end portion of the filament 5 oriented in the direction of the major axis is disposed near the first and second foci F1, F2 of the ellipse. On the reflecting surface of the ellipse light from the first focus F1 is returned to the second focus F2 and light from the second focus F2 travels past the first focus F1 and so infrared radiation reflected by an infrared radiation reflecting film 7 is directly returned to the filament 5 and the reflected infrared radiation is effective in heating the filament 5. The infrared radiation reflected by the infrared radiation reflecting film 7 is dispersed between the two points F1, F2 and is dispersed through the filament 5 to heat the filament 5. Lamp efficiency is thus enhanced.

Title: Antiskid controller
Inventor: MATSUDA TOSHIROU
IPC: B60T8/72
Filed: 1980-06-23
Abstract: PURPOSE: To prevent hunting in the erroneous setting of braking target straight line in such a way that output can be held by shifting input from a comparison circuit to inhibit setting of braking target straight line.  
     CONSTITUTION: Signals of speed in wheels V w  are made into signals in deceleration by a deceleration detecting circuit 8, and when signals in deceleration become higher than the determined value α b , a comparator 9 gives braking target setting signals e b  as output. A circuit part 10 gives signals e o  as output whether or not setting of braking target straight line is allowed, and the signals are transmitted to a control part 11. Since the circuit part 10 has hysteresis characteristics, and input from the comparison circuit to inhibit setting of the target straight line is shifted, even if the signals of speed in wheels are inadvertently changed, output can be held. Since there is no case of setting the braking target straight line erroneously, brake oil pressure can be compatibly controlled.

Title: Printing apparatus and post-treatment apparatus for printed image
Inventor: HIGA RYUJI
IPC: B41F23/00
Filed: 1995-04-10
Abstract: PURPOSE: To remove an excessive ink properly from an image of a body to be printed irrespective of a printing rate of the body in an apparatus wherein the body P after printed is transferred by a touch roller and a confronting roller and the excessive ink is transferred to the touch roller. CONSTITUTION: A feed nozzle 47 supplies an excessive ink-removing liquid to a touch roller 37. The removing ink is not dissolved in a printing ink, having a surface tension smaller than a surface tension of the printing ink. The removing liquid of the touch roller 37 comes into touch with a printed image face of a body to be printed. An excessive amount (c) of the printing ink is transferred to the removing liquid of the touch roller 37 from the body P to be printed, and removed from the touch roller 37 by a blade 45 in accordance with the rotation of the touch roller 37. When a printing rate of the body P is high, a rotating speed of the touch roller is lowered to increase the transferring amount of the ink. If the printing rate is low, the rotating speed of the touch roller is increased thereby to reduce tone transferring amount of the ink.

Abstract: PURPOSE:To prevent substantially the occurrence of dielectric breakdown from feeding electrodes to other structures, by covering the outer portions of a discharge tube and the feeding electrodes with a high-insulative member. CONSTITUTION:The surfaces of feeding electrodes 21a and 22a and a discharge tube 1 except for the fitting portions of the feeding electrodes 21a and 22a and the discharge tube 1 are molded with a silicon adhesive 55.

Besides, the thermal conductivity of the silicon adhesive 55 is about 10<3>-10<4>cal/cm.sec<o>C, that is, considerably higher than that of air. Therefore the lateral side of the discharge tube 1 can be cooled down, and consequently the durability of the discharge tube 1 is improved.
