Filed: 2002-06-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide an apparatus which recovers (eliminates) a powder coating material from air mixed with the powder coating material so that air free from the powder coating material can be discharged into the atmosphere and environmental pollution is completely avoided.  <P>SOLUTION: The recovery apparatus for included powder is provided with filters 1 arranged to stand to block the passage of air having the included powder, with shower disposed above the filters 1 so as to allow water from the shower 5 to fall along the filters 1, and with a water tank 3 having a bag 7 for housing the powder coating material, the bag permeating only water. The shower 5 and the water tank 3 are connected with a pipe 6 and the water in the water tank 3 can be circulated and supplied by a pump p. Because the water falls in a complicated way along the inner and outer faces of the filters, the powder coating material is caught by (the water in) the filters with high probability and air containing no powder coating material can be discharged into the atmosphere. As the shower water can be circulated and used, this results in a large effect to save the cost.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To efficiently carry out the mounting and dismounting operation of a tool for a tool holder made of a non-magnetic material by the shrinkage fit utilizing the electromagnetic induction heating for a heating material made of a magnetic material.  <P>SOLUTION: A shank part 3 of the tool holder 2 is mounted on an apparatus body 1. A tool holding part 5, which has a tool inserting hole 4 and is made of a non-magnetic material, projects upward from the tool holder 2. A cylindrical heating ring 6 made of a magnetic material is fitted in an upper part of the tool holding part 5. When the electromagnetic heating is carried out for the heating ring 6 by supplying a high-frequency electric current to an electromagnetic coil 7 arranged outside the heating ring 6, the heating ring 6 is quickly and effectively heated, and the heat is conducted to the tool holding part 5. When the tool holding part 5 has been sufficiently heated and the diameter of the tool inserting hole 4 has been expanded, a tool T is inserted into the tool inserting hole 4. After that, the heating of the heating ring 6 is stopped, and the heating ring 6 is removed, and then the tool holding part 5 is cooled, and the diameter of the tool inserting hole 4 contracts. As a result, the tool T is tightly gripped by the tool inserting hole 4. Thus, the shrinkage fit of the tool T into the tool holder 2 is completed.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To improve stability of a tracking servo in a tracking error detecting device which can be applied to a recording and reproducing device for a disk recording medium having a meandered guide groove (wobbling groove), and a tracking error detecting method.  <P>SOLUTION: A tracking error signal by a push-pull signal is outputted as a PP system at the time of start of disk rotation. At the time, a meandering frequency is measured, a meandering component detecting means is optimized and set based on the detected result. As a WPP system becomes an accurate error signal in this state, switching is performed from the PP system to the WPP system. That is, it is switched to a state in which a push-pull signal in which an offset component obtained by subtracting a signal amplitude component by meandering from the push-pull signal is removed is outputted as a tracking error signal.  <P>COPYRIGHT: (C)2004,JPO

IPC: G06T3/40
Filed: 2002-08-07
Abstract: PROBLEM TO BE SOLVED: To convert a multi-level image data into an image data capable of printing it at a high speed with a high image quality. SOLUTION: In order to make possible a high-speed printing, a multi-level image data is converted into the image data having a low resolution. In the conversion, two dots adjacent to each other are so collected in a set as to select one dot of the two dots the representing density of which is larger than the one of the other dot. By the conversion into the selected one dot, the multi- level image data is converted into the image data having a low resolution. If doing so, even when the image depicted in an original image is a thin line on a white background, the image data capable of printing it with a high mage quality can be obtained without erasing the thin line.
