IPC: H05B3/10
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a heating device which has uniform heating performance and durability and does not give undesirable influence to an object to be heated. SOLUTION: A heating device 10 includes a heat conductive block body 12 of oxygen free copper in which a heater 11 is built in, and a ceramic titan containing heat resistant hard layer 13 formed on an outer surface of the heat conductive block body 12.

Title: Hemoglobin adsorber
Inventor: SUGIYAMA MASAFUMI
IPC: B01D15/08
Filed: 1987-12-07
Abstract: PURPOSE:To remove free hemoglobin in blood efficiently and selectively by utilizing porous glass with mean pore diameter of specified value which is packed into a column and made into a sterilizable adsorber by bringing in contact with hemoglobin contained in blood. CONSTITUTION:Porous glass used herein is formed by melting an alkali- borosilicate glass, then by heat treating in the region of transition temperature to obtain microfine phase-separation glass wherein one phase is dissolved to form fine pores under acid treatment. The average diameter of the fine pores of the obtained porous glass is 120Angstrom  or more. When the pore-size becomes too large, more amount of total protein is absorbed while lowering the adsorbing capacity of hemoglobin, therefore, the pore-size is preferably 500Angstrom  or below. By packing this adsorbent into a column provided with access openings for blood and by flowing blood continuously, the selective adsorption of hemoglobin can be performed. Since this enables the sterilization of bacteria through high temperature steam or radiation, the obtained adsorbent is suitable for medical treatment.

IPC: G06F3/048
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To obtain an image-recording device which facilitates selection of paper size, when an image is recorded on a recording form sheet placed on a manual paper feed tray. SOLUTION: When a recording part 16 records an image by using recording form sheets placed on a manual paper tray 17, a user designates the size of the recording form sheets from an operating part 12. In this case, when the size of an image to be recorded is unclear, paper sizes other than the size of recording form sheets loaded in a paper cassette are preferentially shown on a display part 13. Also, when the size of the image to be recorded is detected, the size of the image is preferentially shown on the part 13 when it is unmagnified. When magnification is specified, a paper size obtained by converting a paper size based on the specified magnification is preferentially shown on the part 13. Every preferentially shown paper size is a size having high probability of being selected by the user, the operation of the user is reduced and operability can be improved.
