Title: Filter material for purifying water
Inventor: IMADA NORIYUKI
IPC: B01D39/06
Filed: 1983-06-22
Abstract: PURPOSE:To provide a filter material for purifying water for efficiently and economically removing components such as a Mn-component, an iron component or coloring matter in water of a lake or river, constituted of macroporous lumpy MnO2 having surface activity comprising beta-type MnO2 or a mixture of beta-type and gamma-type MnO2. CONSTITUTION:A gamma-type MnO2 powder is used as a stock material and immersed in an acidic solution such as sulfuric acid containing a divalent Mn-ion or a Mg-ion in addition to said Mn-ion. By this method, macroporous lumpy MnO2 having surface activity comprising beta-type MnO2 alone or a mixture of beta- type MnO2 and gamma-type MnO2 is obtained. In this case, the aforementioned immersion time, the temp. of the solution and the compositional concns of the Mn- ion, the mg-ion and the acid are important factors. Thus obtained lumpy MnO2 is coarsely crushed and screened to obtain MnO2 particles with a proper particle size which is then neutralized with NaOH to obtain an objective high performance filter material for purifying water.

Title: Bullet advancing device of toy gun
Inventor: KO SEITAKU
IPC: F41B11/721
Filed: 1995-04-13
Abstract: PURPOSE: To simplify the bullet advancing structure and to conveniently conduct machining and assembling operations by retreating a bullet advancing cylinder together with a slider, then exhausting the air out of a third air passage, returning forward together with the slider, and feeding next bullet to a bullet chamber. CONSTITUTION: If there is a first bullet 18a in a bullet chamber 42, when a trigger 6 is pulled, an air valve 11 is opened, the air is passed from a first air passage 15 to a second air passage 28, and fed to a first air chamber 40 via a fourth air passage. Thus, the bullet 18A is pressed into a gun tube 4 to be injected. In this manner, a bullet advancing cylinder 22 is pressed by a spring 23, advanced, the airs in the passages 15, 28 are introduced into the first air chamber 33, and the bullet advancing unit and the slider 3 including an annular tube 25 are returned together to the original position. At this time, the push rod 17 of the cylinder 22 thrusts second bullet 18B to introduce it into a bullet chamber 42 for waiting the injection for next pulling the trigger.

Title: Woven cloth winding method around cloth roll and weaving machine
Inventor: SUWA MITSURU
IPC: B65H19/28
Filed: 1993-04-15
Abstract: PURPOSE:To prevent generation of winding creases by guiding the end part of woven cloth extended in the rotating direction of a cloth roll between a press roll and the cloth roll and oscillating the press roller for clamping the end part of the woven cloth toward the cloth roll. CONSTITUTION:A motor is operated to oscillate a press roller 24 clockwise to be brought into contact with a cloth roller 90. As the press roller 24 is oscillated clockwise, a part 12c of a woven cloth 2 which goes round the press roller 24 and reaches the lower peripheral surface of the cloth roll 90 is slackened to come down. Thus, the frictional force between the press roller 24 and the woven cloth 12 is suddenly lowered so that the press roller 24 is driven by the cloth roll 90 and the end part 12b of the woven cloth 12 clamped between the press roller 24 and the cloth roll 90 is subjected to feeding force. When the operation of the motor is stopped, the press roller 24 is oscillated by its dead load so that the woven cloth 12 wound round the cloth roll 90 is pressed by the force corresponding to the tension of the woven cloth 12 so as to prevent generation of winding creases.

Title: Obtaining method for hardness-change curve of high performance in nitriding of alloy tool steel
Inventor: TAKASE TAKAO
IPC: C23C8/80
Filed: 1978-09-08
Abstract: PURPOSE:To extend the life-time of alloy tool steel, by forming iron nitride on the surface of the alloy tool steel to a degree which can be detected by X ray diffraction test, then by reheating it so as to decrease hardness gradient from the surface inward. CONSTITUTION:A material to be treated, e.g., molybdenum base high speed tool steel, is nitrided on the surface thereof until iron nitride is detected by X ray diffraction test. The material is then heated to a tempering temp. range to diffuse the nitride. As the result, the hardness gradient is decreased because of the decrease in the hardness of the surface portion and increase in the hardness of the internal portion, so that a hardness change curve which shows good performance of the material is obtained. The change in the reheat treatment time permits the regulation of the hardness gradient. When the nitride is not detected by X ray diffraction test, the gradient is steep because of no increase in the internal hardness. This method allows to extend remarkably the lifetime of the tool steel compared with conventional method.
