Title: Pen point made of resin having ink outflow gap
Inventor: FURUSAWA MITSUHIKO
IPC: C09D11/16
Filed: 1989-07-03
Abstract: PURPOSE:To enhance abrasion resistance, a writing feeling, bending strength and the modulus in bending by preparing a pen point made of a resin by molding a composition prepared by adding fluoroplastic and a thermoplastic liquid crystal polymer having thermal deformation temp. of 100 deg.C (18.6kg/cm<2>) or lower to a polyacetal resin. CONSTITUTION:The abrasion resistance of a polyacetal resin is markedly enhanced by adding fluoroplastic to said resin but the bending strength or modulus in bending thereof is insufficient and, therefore, by further adding a thermoplastic liquid crystal polymer with thermal deformation temp. of 100 deg.C (18.6kg/cm<2>) or lower to said polyacetal resin, the bending strength or modulus in bending thereof is increased. Since the thermoplastic liquid crystal polymer whose thermal deformation temp. exceeds 100 deg.C has high melting temp. and the polyacetal resin is decomposed when molded at said temp., the thermoplastic liquid crystal polymer having an m.p. near to the molding temp. of the polyacetal resin is used in order to avoid said decomposition.

Title: Method and apparatus for soldering
Inventor: NAGATA SHIGENAGA
IPC: B23K3/06
Filed: 1992-06-08
Abstract: PURPOSE:To achieve that a solder, in a very small quantity, which has been heated to a proper temperature is dropped on a work and to perform a soldering operation whose reliability is high and which is homogeneous by a method wherein whether a solder piece has been melted or not is detected by means of a change in the intensity of reflected light by the surface of a molten solder and the molten solder is heated additionally for a definite time while the point of time when the molten solder is detected is used as a starting point. CONSTITUTION:When a solder piece is melted, a solder becomes a liquid and is changed to a ball shape. Its surface becomes a reflecting face; its reflection factor is increased rapidly, and intense reflected light is generated. When a photodetector 124 detects that the solder has been melted, a control device 67 starts a clocking operation by means of a dissolution timer. When a definite time for additional heating elapses, the control device actuates a motor 144, it turns a cam 148, and it pushes and opens both iron support plates and separates an iron element 156. As a result, the molten solder inside a solder melting part which is formed by a groove in an aggregate part is dropped on a work, and a soldering operation is performed. Thereby, the soldering operation which is homogeneous and whose reliability is high can be performed.

Title: Biochemical measuring instrument
Inventor: ARAI MASATO
IPC: G01N21/00
Filed: 1984-08-17
Abstract: PURPOSE:To improve the reliability of the result of a biochemical measurement utilizing color reaction by detecting the coloration degree of test paper before use and correcting a calibration curve. CONSTITUTION:The test paper 8b is inserted between a light emitting diode 10 and a photodiode 11 and the light transmitted therethrough is detected. The output current thereof is converted to a voltage value by an I/V converter and is inputted via an analog-to-digital converter 19 to a CPU20, by which the coloration degree is calculated. The calibration curve is corrected by a correcting means 5. The test paper 8b is then immersed in urine to induce the color reaction and is inserted between the photodiode 10 and the photodiode 11. The coloration degree is similarly detected and the wrine sugar content is calculated in accordance with the calibration curve and is displayed on a display system 4. Even if there is variance in the coloration degree of the test paper itself, the coloration degree after the reaction is exactly detected and therefore the reliability of the measurement result is improved.

Title: Spout
Inventor: KAMEDA KATSUMI
IPC: B65D35/38
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To smoothly turn off a cap by forming a projection on an inner wall of a spout which is a cylindrical opening part to prevent a content from being adhered to an inner surface of a cap of the spout. SOLUTION: A projection is provided on an inner wall of a spout T. The projection 5 is preferably of a shape to resist against the rotation of a cap C. Any moldable shape is acceptable so long as it provides the resistance so that the content is prevented from being rotated together with the cap C when the cap C is opened. When the cap C is rotated to open in order to take out the content from a container M, the content in the spout T is prevented from being rotated by the presence of the projection 5. Thus, the content which is temporarily adhered to a top plate 11 of the cap C is separated from the top plate 11 by the shearing force. As a result, the cap is not opened while the content is adhered or attached to the cap C side.

Abstract: PURPOSE:To obtain a smooth cut surface by reducing the resistance force for the development of crack in a cut part by superposing the shearing stress due to the supersonic wave vibration on the application of tensile strength and cutting a variety of brittle material with high precision. CONSTITUTION:When the repulsive elastic bodies 5 and 6 enveloping a workpiece A are pressurized and compressed by the divided shaping molds 1 and 2, the repulsive elastic bodies 5 and 6 are deformation-developed in the lateral direction with respect to the axis line direction of the workpiece A along the workpiece A, and the deformation strain on the compression surface of the workpiece acts onto the workpiece A by the friction with the surface of the workpiece A. In this moment, the supersonic wave vibration is superposition- applied onto the workpiece A through the vibrating bodies 7 and 8, and the tensile strength in the direction opposite to the axis line direction is increased on the both surfaces of the cut part B inside the workpiece A. Therefore, a locally large stress is concentrated even by a small applied stress, and the superior cut surface can be obtained with high precision.
