Title: Dyeing of aromatic polyamide fiber
Inventor: KURITA MASAO
IPC: D06P3/24
Filed: 1989-02-22
Abstract: PURPOSE:To dye meta-based aromatic polyamide fiber in excellent fastness to light and in good dyeability by using vat dye or soluble vat dye and heat- treating the fiber at high temperature directly in a state of insoluble quinone derivative without exerting reducing action. CONSTITUTION:In dyeing meta-based aromatic polyamide fiber with vat dye or soluble vat dye, the fiber is dyed with the dye at high temperature of 110-170 deg.C directly in a state of insoluble quinone derivative without undergoing a state of hydroquinone derivative by reducing action and, in order to promote dyeing, by adding a compound and an inorganic salt which act as a carrier. By this method, dyed materials having excellent fastness to light are obtained in good dyeability.

Title: Plasma etching method and apparatus therefor
Inventor: KAMIMURA TAKASHI
IPC: H01L21/302
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent defects from occurring in an etching process by monitoring the in-plane distribution of the emission intensity in a treating chamber to detect the variation of etching characteristics. SOLUTION: A treating chamber 1 contains a lower and upper electrodes 2, 3. An etching gas is fed from a gas feed system 4, a vacuum exhaust system 5 is controlled for a specified pressure in the chamber 1, a high frequency power source 6 feeds a power to generate a plasma between the electrodes, thereby etching a wafer 8 on the lower electrode 2 with a plasma emission passed through a window glass 9, a cylindrical lens 10 compresses the quantity of the light in the height direction and guides it to a photo-detector 11 which uses a linear sensor to observe the plasma between the electrodes from one direction parallel to Y-Y', thereby detecting the emission intensity at each of points on the Y-Y' axis. Thus it is possible to detect the variation of the plasma 7 in the chamber 1 to prevent defects from occurring in an etching process.

Title: Correction method for density gradation of dot picture
Inventor: KIYONO TAKESHI
IPC: H04N1/405
Filed: 1986-02-27
Abstract: PURPOSE:To simplify a program or a circuit constitution and to shorten by setting a prescribed functional relation between a reference original density value and a dot area ratio according to the density characteristic of a successive gradation picture and rewriting a threshold every time of the setting. CONSTITUTION:A dot generator 2 has a comparator 9, a density corresponding value from an original reading part 1 and the threshold from a threshold output part 4 are inputted and the density corresponding value is binarized by the threshold. The CPU 12 of the threshold output part 4 reads the dot area ratio PX to the prescribed number of generating the dots from the storage table 14 of the number N of generating the dots - the dot area ratio P. Then, the reference original density value DX to the dot area ratio PX is read from the storage table 15 of the P - reference original density value D. Further, a reading density corresponding value VX to the density value DX is read from the storage table 13 of the D - reading density corresponding value V. Thereby, in the CPU 12, the reading density corresponding value VX corresponding to the prescribed number NX of generating the dots is obtained. The obtained reading density corresponding value VX is used as the threshold.

Title: Close-up photographing changeover device of zoom lens barrel
Inventor: TAKAMORI YASUMASA
IPC: G02B7/105
Filed: 1979-04-04
Abstract: PURPOSE: To ease the close-up photographing changeover operation by making possible the changingover to close-up photographing only when the focusing operation ring and variable power operation ring are put in the specific only one state and making only the variable power operation ring turnable after the changingover.  
     CONSTITUTION: When the variable power operation ring 8 is turned from the state of focusing position infinity at the variable power position minimum focus length, a cam ring 5 cooperatively thrns and the 1st moving ring 2 and the 2nd lens group L II, the 2nd moving ring 3 and the 1st, 3rd lens groups L I, L III and changeover ring 7, etc. move on the optical axis, thereby assuming the focusing position infinity, variable power position longest focus state. Thence, when the focusing ring 1 is turned to the focusing position shortest length, then the lens group L I moves left and the changeover groove 6a and protrusion 7a assume an opposing state so that the changing-over of close-up photographing becomes possible only in the focusing position shortest length, variable power position longest length state. When the changeover ring 7 is moved leftward, the turning of the guide ring 6 becomes infeasible to inhibit turning of the ring 1 and only the ring 8 becomes turnable, thus the close-up photographing changing-over operation becomes easy and sure.

Title: Load receiving stand device of vehicle for loading and unloading
Inventor: HAMAMOTO KAZUHIKO
IPC: B60P1/44
Filed: 1980-03-29
Abstract: PURPOSE: To prevent the load from falling by protruding a load receiving stand stopper except when a load receiving stand is grounded and to facilitate unloading by drawing in the stopper automatically when the stand is grounded or through the manual disengagement of a locking device as necessary.  
     CONSTITUTION: The stopper 8 is pivotally provided at the tip of the load receiving stand 4. Torsion springs 12 are inserted at both sides of the stopper 8.

When the load receiving stand 4 is grounded, the stopper 8 is automatically pivoted to keep itself in one plane with the load receiving stand 4. In case that the unloading location is higher than the ground, after the handle 24 of the locking device 14 is turned for 90° to shift a pin 20 from a notch 23" to a notch 23' and by artificially pivoting the stopper 8 downwards, an engaging pin 17 is inserted to lock the stopper 8 and the load receiving stand 4 in one plane so as to enable the load to smoothly unload from the car floor to the platform.

Title: Aseismatic structre of low-temperature tank
Inventor: HIRATA JIYUNICHI
IPC: F17C13/08
Filed: 1978-04-08
Abstract: PURPOSE:To prevent a tank proper from any horizontal movement at the time of earthquake by binding an end of the skid preventive anchor in an appropriate number to the periphery of the bottom plate of tank proper and penetrating the other end of this anchor through the side plate of tank shell. CONSTITUTION:As the bottom plate 13 of tank proper is penetrating the side plate 10 of tank shell and bound to the anchor wall 17 with the aid of skid preventive anchors 16 in an appropriate number, any horizontal force applied to the tank proper, at the time of earthquake for ex., is transmitted to the slab 8 through the anchor 16 and the wall 17. Therefore the tank proper will not move horizontally. In case any skid force 1F is applied to the tank proper at the time of earthquake, a tensile force is applied to the anchor 16 in the A part as it is fixed from its signel side by means of a bolt etc. On the other hand, no compressive force is applied to the opposite side, the B part, because the wall 17 and the fixing bolt become loose. Thus only tensile force is applied to the anchor 16, which gives a secure prevention against yielding as well as a favourable utilization of the anchor's section.

Filed: 1985-03-04
Abstract: PURPOSE:To improve precision of fuel injection control throughout the entire speed range from low speed to high speed by calculating the injection quantity on the basis of weighted average value of basic injection quantity changing along with lapse of time and setting the calculation cycle at a fixed time period. CONSTITUTION:Quantity of injection from a fuel injection equipment 6 is con trolled by a control unit 12 through computation based on intake air volume detected from an air flow meter 13a, engine rotation speed signals put out from a crank angle sensor 13b and signals from a device 13 for detecting other indexes of engine operation. The control unit 12 conducts such computation control as to reset the count and proceed to the next calculation routine when the time measured with a soft timer or a hard timer reaches a specified calcula tion time DELTAt. Since calculation cycle is thus set at a specified time DELTAt, it is possible to measure intake air volume accurately even at a transitional period and supply sufficiently matching volume of fuel for injection.
