Title: Production of ball-point pen tip
Inventor: NAGASHIMA ISANORI
IPC: B43K1/08
Filed: 1994-09-09
Abstract: PURPOSE: To adjust the shape of the tip of a ball-point pen without distorting the same by holding the pipe made of a synthetic resin of an ink tank and applying grinding processing to the tip part of the ball-point pen while bending the pipe. CONSTITUTION: A pipe 2 made of a synthetic resin fitted with a ball-point pen tip 1 is held between a rubber roll 3a and a receiving roller 3b and rotated by a rotary machine. The grinding surface 4c of a grinder 4 is brought into contact with the ball-point pen tip 1 at the position bending the pipe 2 while the pipe 2 is rotated to apply grinding processing thereto. Even when the contact force of a grinding material is slightly excessive, it can be absorbed by the bending force of the pipe. Further, the contact force is regulated by the holding force of the pipe and the distance with the grinding material.

Title: Test carrier and method for measuring component of liquid reagent
Inventor: HERUMUUTO FURAITAAKU
IPC: G01N33/52
Filed: 1988-09-29
Abstract: PURPOSE: To reduce the required amount of a sample, to control the concentration of a reagent in the sample, and to adjust it accurately by connecting a layer that is bound to a liquid absorption layer impregnated with the reagent to the liquid absorption layer so that the layer does not overlap with a sample application band. CONSTITUTION: Blood is applied to a covering net 5 and a plasma separation layer. Then, a sample is leaked through a plasma net and a plasma separation layer and, in that case, red cell in the blood is separated. Then, the plasma is carried to an evaluation range 3c in the longitudinal direction of a test carrier 1 from the layer in a liquid absorption layer 3. Then, after the absorption layer 3 is rapidly filled with the plasma, the sample enters a reagent layer 7 due to diffusion while changing the liquid carrying direction and the sample reacts with the reagent being impregnated on the layer. Then, when a specific time passes after adding the sample, a pressure plate 9 is pushed down onto the absorption layer 3.  As a result, a reagent support 10 is bound to the plasma that reacted with the reagent impregnated in the reagent layer 7 and the reagent is absorbed in the support 10 by changing the liquid carrying direction, finally generating a detachable signal.

Title: Parallel type analog-to-digital converter
Inventor: YOSHIZAWA HIROSHI
IPC: H03M1/36
Filed: 1984-11-16
Abstract: PURPOSE:To prevent the malfunctions of an A/D converter due to the ON/OFF actions of a switch by setting plural gate means which limit the maximum displacement of the potential of the capacitor of an AC-coupled type comparator between a combined switch and a capacitor. CONSTITUTION:For a parallel type 3-bit A/D converter, the resistances 3-10 produce a reference potential which increase gradually. The reference potential is compared with the input signal given from a terminal 18 by inverters 60-66, capacitors C43-49 and combined switches SW 67-87 through an AC-coupled comparator. MOSFET 33-42 form gate means which limit the maximum displacement of the potential of each capacitors C43-49. The voltage applied to gate terminals 50-54 is increased gradually to a terminal 50 from a terminal 53 after setting the potential of the terminal 54 at OV. While the potentials given to terminals 50-59 are reduced gradually with the potential of the terminal 55 set at the power supply voltage level. Thus it is possible to reduce the level of the spike noise produced at the input of an encoder 19 when switches SW67-87 are turned on and off. This prevents the malfunctions of the parallel type 3-bit A/D converter.
