Title: Thermoplastic resin bag
Inventor: ARAHA SATOSHI
IPC: C08L101/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent an incinerator from being damaged and suppress generation of poisonous gas by suppressing an abnormal rise in temperature of the incinerator at the time of incineration by mixing a specific amount of aluminum hydroxide into thermoplastic resin. SOLUTION: In manufacturing a garbage bag or a shopping bag, thermoplastic resin with 10 to 50wt.% of aluminum hydroxide mixed is formed as a material. The aluminum hydroxide emits water of crystallization under temperature conditions in an incinerator and also transits to active alumina. At this time attenuation effects of combustibles due to filling of inorganic substance and endothermic reaction associated with the emission of water of crystallization reduce a combustion temperature while active alumina adsorbs HCl or heavy metal ions included in ash at the time of landfill to prevent them from leaking. Other inorganic fillers can be also used together with aluminum hydroxide, wherein the inorganic fillers to be used may include calcium carbonate, talc, titanium oxide, aluminum oxide or the like.

Title: Pressure fixing device
Inventor: MORIKAWA TERUO
IPC: G03G15/20
Filed: 1979-10-23
Abstract: PURPOSE: To reduce torque fluctuation for entering and ejecting the toner image support material to and from a pair of rollers to prevent generation of picture blur, by inclining the compression line of a pair of rollers to the tip edge of the toner image support material entering a pair of rollers.  
     CONSTITUTION: Roller 1 is driven and rotated through the driving mechanism by the motor, and roller 2 is inverted and rotated due to frictional force. This motor rotates the photosensitive drum through the driving mechanism and moves the original stand to scan the original. if compression line 4 of a pair of rollers is inclined for the tip edge of toner image support material 3 coming to them, torque fluctuation for insertion and ejection of support material 4 into and from a pair of rollers is reduced. It is very effective if this inclination angle α is 25'W80' for the roller diameter of 20W60mm. Thus, torque fluctuation for entering and ejecting the toner support material to and from a pair of rollers is reduced, so that generation of picture blur can be prevented.

Filed: 1987-05-31
Abstract: PURPOSE:To cut the number of necessary photodetecting means down to one piece by using a control means which controls plural light sources independently of each other and using said means in common between the photodetecting means and an ON/OFF information collecting means. CONSTITUTION:A 1st light source LED1 is turned on in response to the application of a power supply. Then a feed means TF for punch tape T is actuated in response to an information request signal produced from a host computer. A data collecting signal is produced from an initial control means IC when the punched area of the tape T is coincident with the passing area of the optical signal received from the LED1 and a photodetecting means PD detects light. An information collection control means ICC turns on the light source LED 2-LEDn successively except the LED1 in response to said data collection signal and the means PD detects successively the beams of those LEDs. At the same time, the information obtained from detection of the LEDs via the means PD is stored in a memory means M. In such constitution, just a single piece of the means PD suffices and therefore an economical load can be reduced.

Abstract: PURPOSE:To eliminate an influence on the design of an object and to improve the degree of freedom of the design by providing a polarizing filter on the photodetection surface of a photodetecting means transmitting only linear polarized light which is not rotated. CONSTITUTION:Light, which is transmitted through a light reflecting layer 10, of laser light which is made incident on a discrimination seal 3 passes through a polarization plane rotating layer 12 and is reflected by the surface 1a of a card 1 and passes through the polarization plane rotating surface 12 again, so that its plane of polarization is rotated by 90 deg.. In the case where the card 1 is actually discriminated, the card 1 is conveyed and when the discrimination seal 3 is confronted with the light emitting element 6 of a light projection and photodetection unit 5, the light emitting element 6 irradiates the discrimination seal 3 with illumination light of 780nm consisting of linear polarized light in a specific direction. Then, the light which is diffracted and reflected by the discrimination seal 3 is transmitted through a polarizing filter 7 and photodetected by any of respective parts of the light receiving element 8 to discriminate whether the card 1 is a regular card or not according to the photodetection intensity.

Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To prevent unauthorized use by copying an output information matching with collated information by rewriting the collated information and output information when the result of collation at a collating part is true. SOLUTION: A collating part 104 of a function range setter 100 reads the output information sent out of a decoding part 103 and the collation information sent out of a collation information storage part 105 and collates that output information with the collation information. Then, a function range setting part 108 reads information showing the collated result from the collating part 104. When this information is true, the specified function range of a function range storage part 109 such as a function range for permitting the usage of all peripheral devices at the 2nd column, for example, is selected and in order to function all the peripheral devices of a computer 120, signal lines 122 and 123 are connected to a central processing unit(CPU) 121.  Besides, when the collated result from the collating part 104 is false, the function range setting part 108 selects any other function range in the function range storage part 109 and all the peripheral devices are disconnected from the CPU 121 by the signal lines 122 and 123.

Abstract: PURPOSE: To separation-recover high purity Co by selectively extracting Co from a Ni and Co-contg. soln. with an org. solvent and back-extracting the Co in the solvent with an aq. mineral acid soln. while controlling the pH value of the soln. to a certain range.  
     CONSTITUTION: Ni and Co-contg. raw material is treated with an acid soln. to extract the Ni and Co into the aq. soln. This Ni and Co-contg. soln. is contacted to an org. solvent prepared by diluting an alkylphosphonic acid monoalkyl ester of formula I (where R 1  and R 2  are same or different 8W10C alkyl) with kerosine or the like to preferentially extract the Co. At this time, metal ions such as Cu and Zn ions in the soln. are also extracted into the solvent phase. This phase is then treated with an aq. soln. of a mineral acid such as HCl or H 2 SO 4  to back-extract the Co. By adjusting the soln. to pH 1.5W3.5 Co alone is back-extracted as high purity Co. The residual solvent is washed with a mineral acid soln. of pH<1.0 to extraction-remove the Cu, Zn, etc., and the washed solvent is recycled as a selectively extracting soln. for a Ni and Co-contg. aq. soln.
