IPC: G03B21/22
Filed: 2002-03-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide a rear projector which can display large-screen video with rich presence without causing a projection image on a screen to flicker even when large-volume sound is outputted from a woofer for low-tone output.  <P>SOLUTION: The rear projector 1 is equipped with a lower cabinet 13 which stores an image forming part and an upper cabinet 12 where a screen body 51 is provided. In the front of the lower cabinet 13, two woofer boxes 60 for low-tone output are provided and on each of the right and left flanks of the upper cabinet 12, a speaker box 70 for high-tone output is provided. The woofer boxes 60 are stored in the lower cabinet 13, so vibration is hardly transmitted to the screen body 51 on the side of the upper cabinet 12 and a reflecting mirror in the upper cabinet 12 and then even when large-volume sound is outputted from the woofer boxes 60, an image on the screen body 51 never flickers.  <P>COPYRIGHT: (C)2003,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To switch a compressor 2 between a case where it is driven by an engine and a case where it is driven by a motor.  <P>SOLUTION: A helical spline 3b is formed in a shaft 3a of a motor 3 to connect a second gear 6 with the shaft 3a. Thereby, when the shaft 3a of the motor 3 rotates, the second gear 6 moves to the first gear 5 side to mesh with the first gear 5. Since the second gear 6 is moved by a coil spring 7 when the motor 3 stops, engagement of the first gear 5 and the second gear 6 is released.  <P>COPYRIGHT: (C)2003,JPO

Title: Method for charging coal
Inventor: NUMAZAWA MAKOTO
IPC: C10B31/02
Filed: 2002-03-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for charging coal which can prevent or control channeling of gas in a pressure-feeding tank at the terminal stage of conveyance.  <P>SOLUTION: The method comprises charging coal 1 into a carbonizing room 14 of a coke oven by air conveyance. When residual coal weight (kg) within pressure-sending tank 2 has become weight calculated from the product multiplied a conveying mass flow rate (kg/sec) of the coal 1 by a stopping time (sec) of an exit valve 2c in the pressure-sending tank 2, stopping of the exit valve 2c in the pressure-sending tank 2 is started, and the exit valve 2c in the pressure-sending tank 2 is stopped prior to total discharge of the coal 1 within the pressure-sending tank 2. The effect of this method is to be able to control or prevent a channeling phenomenon at the terminal stage of conveyance without adding an excessive residual coal amount for determination of a volume of the pressure-sending tank, and to control carry-over of coal powder from the carbonizing room as well as to reduce a capacity of a dust collection facility for treatment of exhaust gas after separation of solidified gas.  <P>COPYRIGHT: (C)2003,JPO

IPC: B65D65/40
Filed: 2002-03-19
Abstract: PROBLEM TO BE SOLVED: To provide, in a field of containers wherein a heat seal of a hermetic container is peeled for unsealing, a packaging material and a container which has an appropriate peeling strength, does not cause paper of-the container to peel even when the material is used as a lid of a paper container with a polyethylene coated on an innermost layer, and exhibits easiness in unsealing. SOLUTION: The packaging material comprises at least a base and a heat seal layer which has a lamination structure comprising, in the sequence from a side closer to the base, a resin layer (B) made of a low density polyethylene, and a resin layer (A) containing 55 to 75 pts.wt. of the low density polyethylene and 45 to 25 pts.wt. of a polybutene-1. The resin layer (A) and the resin layer (B) are adjacently laminated by a co-extrusion method. If the packaging material is heat-sealed as a lid of a paper cup container having a polyethylene with a melting point of 105 to 115 deg.C coated on the innermost layer, the resin layer (A) causes a cohesive failure when the container is unsealed.

Title: Flush valve
Inventor: MATSUMOTO OSAMU
IPC: E03D3/06
Filed: 2002-03-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a flush valve which is excellent in operation stability and durability.  <P>SOLUTION: A driver part 14 is mounted at an upper end of a valve stem 1, and an upper area of the driver part 14 serves as a water chamber 20. The valve stem 12 is ascendably/descendably held by a stem guiding part 13a of a valve holding member 13. When a drainage line 30 is opened by operating an opening/closing operating valve 31, stored water in the water chamber 20 is discharged to a secondary side 3 of a channel, and concurrently with that, a valve element 11 ascends with the driver part 14, so that water supply can be started. When the drainage line 30 is closed by the valve 31, water flows into the water chamber 20 through a water passing hole 13b and a communication hole 14a along with the descent of the valve element 11, the valve shaft 12 and the driver part 14 by self-weight; and the valve element 11 seats itself so as to stop the water supply. The stability of the ascent/decent of the driver part 14 is enhanced because the valve stem 12 is slid in the guiding part 13a which is fixed to a housing 1. Sliding resistance can be made smaller because an outside diameter of the valve stem 12 does not have to be enlarged; frequency of failures is decreased; and an influence exerted by corrosion and garbage can be reduced.  <P>COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To realize effective encoding of interlaced scanning video sequence. SOLUTION: An input image (1) is divided into small blocks of image data (2), and two fields in each of the blocks are inspected concerning correlation (3).
