Title: Bleach-fix solution
Inventor: KOBOSHI SHIGEHARU
IPC: G03C5/38
Filed: 1983-02-17
Abstract: PURPOSE:To speed up silver bleaching by incorporating diethylenetriaminepentaacetic acid ferric complex salt and regulating pH to a specified value. CONSTITUTION:Diethylenetriaminepentaacetic acid ferric complex salt is contained and pH is regulated to >=5.0. In a bleach fixing soln. using an ordinary aminopolycarboxylic acid ferric complex salt, oxidation reduction potential rises with rise of pH, but in the bleach fixing soln. using this diethylenetriaminepentaacetic acid ferric complex salt, the rise of reduction potential is very small. On the other hand, the bleaching speed of image silver almost coincides with the result of oxidation reduction potential, and in a bleach fixing soln. composed of usual aminocarboxylic acid ferric complex salt, the bleach fixing force drops abruptly at >=6.8, especially, >=7.5 in pH, but on the contrary, in the bleach fixing soln. made of diethylenetriaminepentaacetic acid ferric complex salt, desilvering speed does not drop at all even if pH is raised, and higher bleaching force can be retained.

Abstract: PURPOSE:To collect a supplied absorbing liquid by an absorbing part without downwardly flowing the same to a dust removal part, by providing trough shaped containers arranged in a state mutually staggered in an up-and-down direction and a means for collecting the absorbing solution flowing down along the side wall of the absorbing part to the lower part of the absorbing part. CONSTITUTION:In a wet waste gas desulfurization apparatus, collectors 29 arranged to the lower part of an absorbing part 20 for absorbing and removing SOx in two alternately stages and a ring shaped trough 33 having an upwardly opened part is arranged to the inner periphery of the inner wall of the absorbing part 20. Exhaust gas having received dust removal treatment under cooling in a dust removal part is flowed though collectors 29A, 29B and receives the spraying of an absorbing solution in the absorbing part 20 to absorb and remove SOx in the exhaust gas. The absorbing solution flowing down along the side wall among liquid droplets having absorbed SOx is collected by the ring shaped trough 33 and the other liquid droplets falling through the central part of the absorbing part 20 are collected by the collectors 29A, 29B and the collected absorbing solution is returned to the recirculation tank of the absorbing part 20. By this method, the recirculated slurry of the absorbing tower is not downwardly flowed to the dust removal part and the amount of unreacted limestone in the recirculated slurry of the dust removal part is reduced without adding sulfuric acid to make it possible to enhance the purity of the byproduct gypsum.

Title: Multilayer wiring structure
Inventor: YAMAZAKI TORU
IPC: H01L21/3205
Filed: 1985-02-12
Abstract: PURPOSE:To prevent the occurrence of wiring breakdown, by specifying a ratio between the thickness of an interlayer insulating film and an interval between the first layer metal wirings. CONSTITUTION:When the thickness of an interlayer insulating film 4 becomes 1/2 or more of an interval between first layer aluminum wirings 3, a recess part 7 becomes almost invisible. With the interval between the first layer alumi num wirings being constant, the thicker the interlayer film 4 becomes, the smaller the recess part 7 tends to become. When the interlayer insulating film 4 becomes too thick and becomes larger than the interval between the first aluminum wirings 3, however, film stress becomes large, and cracks are yielded in the interlayer film. The depth of through-hole contact connecting the second layer aluminum wirings and the first layer aluminum wirings becomes deep, and wiring breakdown occurs in the second layer aluminum wirings at the contact part. Therefore, it is suitable that the thickness of the interlayer insulat ing film 4 is 1/2-1 times the interval between the first aluminum wirings.

Abstract: PROBLEM TO BE SOLVED: To produce a tubular container having a liner layer without reinforcement, which does not include any foil layer, by applying an aqueous adhesive on a body layer made of cardboard and heating it to evaporate a part thereof and sticking a polymer liner layer on the cardboard body and winding up it around a forming mandrel. SOLUTION: The edge of a body layer material 13 made of cardboard is formed diagonally through a pair of oppositely arranged cutters 31 diagonally cutting an edge. And an aqueous adhesive is applied on the upper face of the body layer 13 through an adhesive-applicator 34. And at least a part of the water content is evaporated out of the adhesive by a heater 35 to make it adhesive. Subsequently, the body layer 13 is forced to pass a holding and pressing roller 36 to laminate the liner layer 14 supplied from a reel 40 and the adhesive is applied on the diagonally cut face of the edge of the body layer 13 through the adhesive-applicator 34 for the diagonally cut face. Then, the laminated layer of the body layer 13 and the liner layer 14 is led to pass through an infrared ray heater 45 and wound up on a forming mandrel 47 to form a spirally wound tube having a hermetically sealed linear joint.

Title: Lens barrel
Inventor: HASHIMOTO SHIGERU
IPC: G02B7/04
Filed: 1979-03-02
Abstract: PURPOSE: To prevent the movement of the lens owing to the own weight of the lens and prevent focus deviation even for the photographing of both horizontal and vertical directions by changing the load upon the lens movement according to the horizontal and vertical posture photographing of the camera.  
     CONSTITUTION: In the photographing close to a horizontal posture, an operating ring 1 is put in the first click position and a click spring 3 is fitted in the first click groove 2a. In this state, a spring piece 12a is riding on the protruding part 4b' of an outer barrel 4b, so spring action does not act. Hence, the turning of the ring 1 may be done smoothly. Next, in the photographing close to a vertical posture, the operating ring 1 is fitted into the second click groove 2b, which the spring piece 12a is held between the protruding part 4b' of the helicoid barrel and a stationary barrel 18. Hence, the spring acts to make the turning of the operating ring heavy, whereby the movement of the lens owing to its own weight is prevented.

Abstract: PURPOSE:To make thin a motor unit and to increase freedom in the utilization of installation space by constituting the motor unit, to be employed in a door power window regulator for automobile or the like, of a flat motor and forming a gear for transmitting driving force to the armature of the flat motor. CONSTITUTION:Upon application of a voltage onto the armature 81 of a flat motor 8 having outer periphery formed with a spur wheel, the armature 81 starts to rotate. The rotary force is transmitted to a reduction gear 9 thence to a pinion 2 secured to the rotary shaft 91 thereof under decelerated state. Rotation of the pinion 2 causes to drive a fan gear 3 which then moves a main arm 4 and an auxiliary arm 5 thus moving a window glass 7 supported on a glass holder 6. The motor unit 8 is made thin because it is coreless and the weight thereof is reduced because no worm is required while furthermore freedom is increased in the utilization of door space because the profile thereof is made simple.
