Title: Flow cell for biosensor
Inventor: ISOBE KENSUKE
IPC: G01N35/08
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To enable stable continuous measurement by preventing the propagation of various bacteria in a passage or the adhesion of slime to the inside of the passage by adding an antibacterial substance to the inner wall of the passage of a flow cell. SOLUTION: Antibacterial tubes 9 are arranged in the passages 6a, 6b of a flow cell 1 and an antibacterial sheet 10 is arranged in a liquid sump part 7 to suppress the propagation of various bacteria in the passages 6a, 6b or the adhesion of slime thereto caused by the operation of a biosensor. In the flow cell 1 using the tubes 9 and the sheet 10, an increase in the adhesion amt. of slime with the elapse of day is extremely reduced. Therefore, the replacement of the flow cell 1, the killing of various bacteria and the washing of the passages 6a, 6b become unnecessary and stable continuous measurement becomes possible over a long time.  By this constitution, since an antibacterial chemical substance, for example, silver or titanium oxide is used in the inner wall of passages, the propagation of various bacteria or the adhesion of slime is hard to generate and long-term continuous and stable measurement can be executed.

Title: Damper for rotor
Inventor: MOTOSAWA YASUKI
IPC: F16F9/346
Filed: 1984-05-04
Abstract: PURPOSE:To provide possibility of rotation at a substantially constant speed even when the rotor is positioned horizontally or vertically by damping the revolving speed of the rotating element of the rotor, rotating by its own weight, using a damper of piston type. CONSTITUTION:A damper of piston type 10 is installed between the stator and rotor so as to damp the revolving speed of rotor, such as a rotary roof box installed at the undersurface of the roof of a car. At the inner surface 11a of a cylinder 11 of said damper 10, an axially stretching groove-shaped flow path 18 is formed to enlarge the flow path when the damper 10 is elongated over a certain specific length. Accordingly the damping action of cylinder type damper 10 is great while the revolving moment by the own weight of the rotor is large, and the damping action is reduced by said groove-shaped flow path 18 from the specific elongational position where the revolving moment begins lessening. This can make the revolving speed of the rotor approx. constant.

Title: Opening part forming method
Inventor: YOTSUMOTO SHU
IPC: H05K3/46
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To provide an opening part forming method with which the opening property of a via is satisfactory and an insulating layer is rigidly cured. SOLUTION: A photomask 40 whose shielding area is 90 μm is used, an insulating layer 30 is exposed with the exposure quantity of 500 mJ/cm2, and an insulating layer 31 exposed by using the photomask 40 is exposed with an exposure quantity of 1,000 mJ/cm2 by using a photomask 50 of 200 μm shielding region. A bottom diameter becomes comparatively large, and the opening property of a via becomes satisfactory. The interlayer connection of a conductor pattern in the via becomes satisfactory. Since the curing of the insulating layer 32 is sufficient, the insulating layer 32 is made difficult to the peeled, the number of pin holes becomes smaller, and shorting of the insulating layer can be prevented.  Even if dust and the like are stuck to the photomask 40 and even when a non-exposure part exists, the probability of the photomask 50 being stuck with dust and the like to a part which is identical to the photomask 40 is low. Thus, occurrence of the holes in the insulating layer 32 can be prevented.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To apply an appropriate electrostatic charge quantity to toner without disturbing a toner layer on a developer carrier at the time of visualizing a latent image on an image carrier with a one-component developer. SOLUTION: A voltage where DC and AC components are superimposed is applied from a power source 6 to the gap between a layer forming member 3 and the developer carrier 2. This voltage satisfies a condition expressed by 3>|Vbias-(Vdc±Vpp÷2)|>0.5, when the DC component is defined as Vdc(kV), the peak-to-peak voltage of the AC component is defined as Vpp(kV) and the DC component of a developing bias voltage applied to the developer carrier is defined as Vbias(kV) and the frequency(f) of the AC component is set for >=3kHz. Thus, the toner is excellently electrified without causing attraction to the layer forming member 3 and reciprocation in the gap.
