Title: Spacing mechanism for printing
Inventor: FURUKAWA HIDEYUKI
IPC: B41J19/30
Filed: 1990-11-29
Abstract: PURPOSE:To make regulation possible to dampen vibrations occurring to a printing section by a method wherein two stepping motors are made to start on driving at different accelerations with a time lag given to the starting of a second stepping motor, or the two motors are made to start on driving at the same acceleration with the time lag kept as in the former case. CONSTITUTION:A first stepping motor 1 is made to start on driving at an acceleration in either directions marked with an arrow A or an arrow B, and a second stepping motor 2 is made to start on driving, with a time lag t1 given, at an acceleration 7, bigger than the acceleration alpha, in the same direction as the rotation of the first stepping motor 1. In another case, the second stepping motor 2 is made to start on driving with the same time lag t1 given at the acceleration alpha, and the time lag t1 is maintained for the rest of the operating time. By making both the stepping motors operated by the method as mentioned above, vibration occurring at the starting can be reduced and, at the same time, the vibration occurred can be damped quickly.

Title: Manufacture of printed wiring board
Inventor: TANIGAMI SHUNZO
IPC: G03F7/38
Filed: 1990-11-29
Abstract: PURPOSE:To prevent the imperfect development of an exposed dry film by a method wherein a copper clad laminated board where the dry film has been laminated is stored at a dark chamber kept at a temperature of 15 deg.C or below. CONSTITUTION:A copper clad laminated board where a photosensitive resin film has been laminated is stored in a dark chamber kept at a temperature of 15 deg.C or below. A dry film photosensitive resin film is laminated on a usual copper plated laminated board used for the formation of a printed wiring board through such a manner that the photosensitive resin film is made to overlap the copper clad laminated board as a polyethylene film is separated off from the photosensitive resin film, and the copper plated laminated board on which the resin film has been laminated is made to pass between heating rollers as compressed. The film concerned is stored in a dark chamber for 20 days and then exposed to light for the formation of a wiring pattern, which is developed with a 1% Na2CO3 solution at a temperature of 30 deg.C. At this point, if a specimen film is stored at a temperature of 15 deg.C or below, the film is fully protected against reddening when it is developed. Moreover, when the copper plated laminated board is etched with a copper chloride etching solution, imperfect etching hardly occurs. By this setup, the imperfect development of a photosensitive film can be prevented.

Abstract: PURPOSE:To obtain an agricultural chemical composition good in diffusivity in water when thrown in paddy field without any practical problems by blending an active ingredient of an agricultural chemical with a water-immiscible organic solvent, a surfactant, a carbonate and a solid acid in a specific composition. CONSTITUTION:The objective composition is a solid agricultural chemical composition for paddy field composed of an active ingredient of an agricultural chemical such as a herbicide, a germicide, an insecticide or a plant growth regulator, a water-immiscible organic solvent such as xylene, ethylbenzene or chlorobenzene, a surfactant (e.g. an anionic or a nonionic surfactant), a carbonate such as sodium carbonate and a solid acid such as citric acid or succinic acid. The composition is applied in an amount of 200-1500g for 10 ares and 5-50 pieces of application for 10 ares. The composition has good diffusivity in water when thrown in the paddy field regardless of the kind or content of the active ingredient. Treatment marks of soil surface with the chemical around the point where it is thrown in can be more reduced. If the treatment marks are formed, they diffuse in a short time without remaining thereafter. There is hardly any difference in pharmacodynamic effects between the point where the composition is thrown in and distant points.

Title: Connecting method of twist pair wire
Inventor: SUZUKI MASAHISA
IPC: H01B13/012
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To twist a paired wire up to a neighbouring area of the connector. SOLUTION: A pair of twisted wires made by twisting two wires together are pulled apart so that they become distant from each other at a side where a terminal for connector is connected, and two wires at the side of connector are released from twist by compressing the twisted part adjacent to the terminal for connector toward the other side where the pitch of twist becomes dense. In this released condition, the terminals of each wire are inserted and fixed to the connector, and the original pitch of twist is restored up to the neighbouring area of the terminal for connector, by squeezing the part where the pitch of twist is condensed, toward connector connecting side.

Abstract: PURPOSE:To make exact simulation in a short period of time by forming the vessel of a test liquid to a specific shape and evaporating a part or the whole of the test liquid at least once. CONSTITUTION:The vessel of the test liquid 3 is formed to the shapes expressed by equations I, II and a part or the whole of the test liquid is evaporated at least once. While the falling speed of the liquid surface of the test liquid 3 is constant regardless of the sectional area of the vessel 1, the thickening of the soln. in the part where a sample 2 is held immersed increases. The need for processing the sample is then eliminated and the problem of deterioration by surface flaws is eliminated so that the corrosion resistance is exactly evaluated. Accurate simulation is made in a short period of time. In the formulas I, II, Hs is the height from the bottom end of the vessel up to the top end of the sample, He is the height after Hs is subtracted from the liquid surface height before the liquid is evaporated. Vs is the volume of the test liquid up to the height Hs and Ve is the volume after Vs is subtracted from the volume of the test liquid before the liquid is evaporated.
