Title: Production of porous titanium-nickel alloy
Inventor: SUZUKI YOSHIKAZU
IPC: C22C1/08
Filed: 1989-05-08
Abstract: PURPOSE:To form an alloy into a suitable porous state by heating a green compact consisting of Ni powder and Ti powder up to a temp. right under the temp. at which self-exothermic melting is started, heating and melting the above green compact under reduced pressure, and then carrying out solidification by means of rapid cooling. CONSTITUTION:A green compact consisting of a mixture of Ni powder and Ti powder is heated up to a temp. right under the temp. at which its self- exothermic melting is started. The resulting heat-treated product is subjected, in the above state or, preferably, after previously cooled, to heating up to the temp. of the self-exothermic heating-initiating temp. or above. Reaction pressure is maintained under reduced pressure or, usually, at a value in the range of 10<-1>-10<-3>kg/cm<2>. By the above heating, a part of oxygen and also a part of hydrogen contained in the green compact are dissociated, and both mentioned above cause exothermic reaction, by which the melting and alloying of the green compact can be attained and also a large amount of gas is generated. After the melting and alloying are finished, rapid cooling is carried out to solidify the resulting molten matter, by which a porous Ti-Ni alloy can be produced.

Title: Image processor
Inventor: SASANUMA NOBUATSU
IPC: G03G15/00
Filed: 1991-05-21
Abstract: PURPOSE:To improve the accuracy of detecting density by switching a density conversion method for a feed-back system in accordance with the method in the case that a tone reproduction method is different at every color. CONSTITUTION:A specified tone pattern is successively formed on a drum in the circumferential direction before performing a copying operation, and then, by measuring with an LED 8 and a sensor 9 at an optimum timing, the tone characteristic is obtained by a series of density value groups without transferring and fixing an image to a copying sheet. In order to compensate the printer characteristic, an LUT 25 is obtained by a printer characteristic which is obtained by measuring. That means, the LUT 25 is obtained by reversing the input/output relation of the printer characteristic. Thus, by periodically performing this operation before performing the copying operation, and successively forming the LUT 25, the tone reproduction characteristic is obtained. By forming a reference image at the time of constituting the feed-back system on a medium by use of the tone reproduction method same as the tone reproduction method for the inputted image data in such a way, the tone control can be accurately performed in accordance with the tone reproduction method.
