Title: Photosensitive material drying device
Inventor: KATSUMATA MITSURU
IPC: G03D15/02
Filed: 1992-11-27
Abstract: PURPOSE:To rapidly dry a photosensitive material by heat rollers with good dimensional stability. CONSTITUTION:A squeeze roller 48, the heat rollers 50, 51 and a discharge roller 52 are provided within a drying chamber 45A of a drying section 45, by which a transporting path to transport a film 14 by bringing this film into contact with the heat rollers 50, 51 is formed. The heat rollers 50, 51 are heated by halogen lamps 56 in their axial central parts, by which the heat roller 50 is kept at, for example, about 80 deg.C and the heat roller 51 at, for example, 40 deg.C. The heat roller 51 is formed larger in thickness t2 and outside dimension D2 than the heat roller 50 and is thereby increased in heat capacity. The film is subjected to rapid constant rate drying at a high temp. by the heat roller 50 then to reduced rate drying at a low temp. by the heat roller 51. The film is thus uniformly dried without the rapid increase of its surface temp. to a high temp.

Filed: 1987-12-16
Abstract: PURPOSE:To improve printing quality by making the interval between a plurality of discrete groups of thermal elements almost 1/2 to at most 1/2 of the interval between the thermal elements in a group. CONSTITUTION:Each end of a plurality of thermal elements 1 provided in parallel are connected to a common electrode 2, while the other end of discrete groups G-1-G-4 of thermal elements 1 are connected to each group electrode. In a thermal head 11 with the above-mentioned thermal element structure, the interval d-2 of thermal elements of groups G-1-G-4 is set to the value equal to almost 1/2 to at most 1/2 of the interval d-1 between thermal elements of the groups G-1-G-4. Under this constitution, the printing dots become continuous even by a slight blotting phenomenon, if some adjoining thermal elements become heated behind the other between the groups. As a result, the inter-group printing dots become continuous when the intra-group printing dots are continuous, and the quality of low-speed printing with low power is improved.

Title: Chemical filter for purifying gas and its manufacture
Inventor: FUJIWARA GORO
IPC: B01D39/14
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a chemical filter for purifying gas in which performance is high and pressure drop is small and contaminant scarecely generates from the chemical filter itself. SOLUTION: The chemical filter for purifying gas is manufactured by a sheet-manufacturing method by using ion exchange fiber and fibrous active carbon together with glass fiber it necessary. The chemical filter may be manufactured by mixing these fibers and manufacturing sheets from the mixture or by individually manufacturing sheets and thereafter laminating the sheets. Pure water in which specific resistance exceeds 1MΩcm is desirably used for manufacturing sheets. A special limit is eliminated in a method for manufacturing sheets. Substance generating dust is less in comparison with a nonwoven fabric filter produced in a dry method. Since the manufacture is completed with a small amount of binder, the rate of used available ingredients is high. The chemical filter is durable for use of a long period or pressure drop is made small.  The chemical filter is safely used for the circulation system of a clean room.

Filed: 1993-11-26
Abstract: PURPOSE:To develop a conductive structure keeping almost permanently suitable conductive performance, which is equipped with an electric conductivity on a surface and free from generation of fuzz of conductive fiber or its omission therefrom. CONSTITUTION:A composition for curing [principal component: polyester acrylate prepolymer containing 50wt.% of zinc oxide powder] is applied to a PP film, and cured by irradiating it with electron beams to make a thermoplastic film C with a crosslinked cured film (c1) on one side surface. Separately, a conductive unwoven fabric (B; weight per unit area 50g/m<2>) is prepared of 30wt.% of pitch based carbon fiber and 70wt.% of PP based composite fiber. Then, the B is superimposed on one side surface of a base material PP sheet A (1mm thickness). Further, the C is superimposed so that its resin side comes in contact with the B. A laminated material of the A, B, and C is integrated by fusion weld by passing it through a heating roll and a cooling roll to obtain a conductive structure. In that case the (c1) comes in contact with the heating roll. Thereby, injury-receiving resistance becomes about three times, and ommission of the conductive fiber comes to be all gone.

Title: Diagnostic system
Inventor: BABA YOSHINORI
IPC: G01R31/317
Filed: 1987-12-21
Abstract: PURPOSE:To conduct a test at high speed without considering the tester skew between both electrode inputs by using a test pattern which sets one side input of a differential amplifier as an intermediate level. CONSTITUTION:When the test is conducted while an input pin B is held at the intermediate level, the test pattern applied to an input pin A can ignore the influence of the tester skew because a test pattern applied to the pin B has a fixed value. Levels outputted to output pins C and D have normal waveforms even if timing is deviated owing to the tester skew of the pin A. Then observation timing is adjusted to conduct the test.
