Title: Low thermal shrinkage polyester support and thermal development photographic photosensitive material
Inventor: HASHIMOTO NARIKAZU
IPC: B29C55/14
Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To prevent the distortion and color dislocation of the image of a thermal development photographic photosensitive material by arranging the dimensional change with the passage of time of a polyester support after heating corresponding to thermal development, in both the machine direction and the transverse direction, within a specified range. SOLUTION: In this low thermal shrinkage polyester support, the dimensional change with the passage of time after being heated corresponding to the thermal development, in both the machine direction(MD) and the transverse direction(TD), is arranged within -0.03-0.05%. The dimensional change with the passage of time after heating corresponding to thermal development means the ratio between the dimensional measured after a process in which a specimen is heated at 115 deg.C for 30 sec and allowed to stand for 5 hr and the difference between the above dimension and the dimension measured after a process in which the specimen is further allowed to stand at 55 deg.C for 72 hr in order to give a change forcibly corresponding to treatment in which the specimen is allowed to stand at 25 deg.C for at least three years.  Moreover, when the dimensional change with the passage of time after heating corresponding to the thermal development is measured over the transverse direction of the support, the absolute value of the difference between the maximum and time minimum, in both MD and TD, is preferably 0-0.04%.

Title: Gold recovering method
Inventor: TOGAWA EIJI
IPC: C22B11/08
Filed: 1979-11-06
Abstract: PURPOSE: To recover gold efficiently and inexpensively by blowing air or O 2  into a plating bath contg. gold cyanide ions and stannous ions, then by treating by an electrolytric method or with an ion exchange resin.  
     CONSTITUTION: Air or O 2  is blown into a plating bath or the like contg. gold cyanide ions and stannous ions to convert divalent Sn ions into stable tetravalent ones, and gold is deposited on a stainless steel cathode by an electrolytic method and recovered. At this time, tetravalent Sn ions are not deposited at all. Gold or gold cyanide ions may be recovered with an ion exchange resin. By this treatment no tetravalent Sn ion is trapped in the resin. Thus, gold can be recovered inexpensively and easily without requiring troublesome purification unlike a conventional method.

Filed: 1993-06-15
Abstract: PURPOSE:To reduce the generation of high-concentration ozone by constituting an organic photoreceptive drum, a corona electrostatic charge means and fixing means in a vertical direction in turn from a lower part. CONSTITUTION:Since the fixing device 18 is positioned at the upper part of an image forming device, the temperature of air near the fixing device 18 arrives at about 80 deg. and the specific gravity thereof becomes light, the air near the fixing device 18 in a duct 17 flows to the outside of the image forming device. On the other hand, the high-concentration ozone is included in the air near the corona electrostatic charger 6 and the air near the charger 6 flows in the direction of the fixing device 18 from the neighborhood of the charger 6 together with a paper carried inside the provided duct 17 according as the air near the fixing device 18 is moved. Therefore, the air including the high- concentration ozone generated by the charger 6 is passed through the fixing device 18 and the ozone is thermally decomposed at this time. Then, the thermal decomposition of the ozone is promoted by the high temperature of the heat source of the fixing device 18 and the high-concentration ozone is reduced.

Abstract: PURPOSE:To ensure the steady generation of the saw-tooth waves by detecting the fixed voltage is secured in the fixed time after the rise of the saw-tooth wave via the saw-tooth wave generator circuit which can vary the inclination of the saw- tooth wave and then feeding the detection output back to the generator circuit as the control signal. CONSTITUTION:Output voltage V1 of reference voltage generator circuit 1 is applied to one input of voltage comparator circuit 2, and output V3 of the saw-tooth wave sent from saw-tooth wave generator circuit 3 which rises up in synchronization with reference voltage V2 is applied to the other input of circuit 2. And pulse V4 is delivered when the coincidence is obtained between voltage V1 and output V3 of the saw-tooth wave sent from circuit 2.

Abstract: PROBLEM TO BE SOLVED: To prevent a reception signal with deteriorated transmission quality from being selected. SOLUTION: Reception signals R1, R2 received from the air via antennas 1, 2 are given respectively to receivers 3, 4 from which reception data D1, D2 are reproduced.
