Publication number: 20040125220Abstract: A digital camera has a display such as an LCD. A viewfinder image obtained by a CCD before photographing is displayed on the display, and a pointer which can be moved up, down, right and left by operation of the user is displayed so as to be superimposed on the viewfinder image. A histogram indicative of a luminance distribution of the whole viewfinder image and a marker indicative of luminance of a pixel of a portion designated by the pointer are displayed so as to be superimposed on the viewfinder image. By displaying the marker, the user can grasp luminance information of a part of the viewfinder image.Type: ApplicationFiled: April 24, 2003Publication date: July 1, 2004Applicant: MINOLTA CO., LTD.Inventors: Akira Fukuda, Toshio Nagai, Tsutomu Honda

Publication number: 20020093582Abstract: A digital camera functioning as a data communication terminal generates a “new file for transmission” which is a new file by copying data contents of an “original file for transmission” which is a file to be sent to a server, and transmits the new file for transmission to the server after giving a file name which is different from a file name of the original file for transmission to the new file for transmission. The file name after changing has a variable part having a number which increases in accordance with a number of times of send. For example, as for an original file for transmission “PIC00001.JPG”, the file name is changed to “00100001.JPG” in the first transmission and “00200001.JPG” in the second transmission. Therefore, the server recognizes these files as different files, so that it is possible to prevent the file from being overwritten by mistake.Type: ApplicationFiled: January 7, 2002Publication date: July 18, 2002Inventors: Taizou Aoki, Akira Fukuda, Masahito Niikawa

Patent number: 6100599Abstract: A portable generator includes a metal shroud surrounding at least a crankcase and a cylinder block of an engine. The engine is directly mounted to the shroud. The shroud forms an effective radiating element and gives an additional heat-radiating surface to the engine, thereby increasing the heat radiation capacity of the engine. Heat generated from the engine while running can, therefore, be radiated efficiently. The shroud is mounted within a sound insulating case, so that the portable generator has a double sound-insulating structure. The noise-proofing property of the portable generator is, therefore, very high.Type: GrantFiled: January 15, 1999Date of Patent: August 8, 2000Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshifumi Kouchi, Akira Fukuda

Patent number: 6091160Abstract: A portable generator comprises a shroud for covering at least a crankcase and a cylinder block of an engine thereof. The shroud is formed of split halves. The engine is fixed to the shroud having its upper part connected to a carrying handle of a sound insulating case. As a result, the load of the engine is applied to the carrying handle through the shroud when the portable generator is lifted up with a hand. It is thus not necessary to increase rigidity of the case, thereby enabling lightening of the case. The generator arrangement also provides an improved soundproof effect since the engine, a source of noise, is covered with the shroud and the sound insulating case.Type: GrantFiled: January 15, 1999Date of Patent: July 18, 2000Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toshifumi Kouchi, Akira Fukuda

Patent number: 6067945Abstract: An engine generator includes an engine having an intake device and an exhaust device which are connected to an engine body, a generator connected to the engine, and a fuel tank for supplying fuel to the engine. The engine, the generator and the fuel tank are mounted on a frame. In this engine generator, the intake device and the exhaust device are connected to an upper portion of the engine body having a cylinder axis extending vertically to protrude to opposite sides from the engine body, and the fuel tank is disposed sideways of the engine body and the generator below the intake device or the exhaust device. Thus, when a vertical engine is used, the fuel tank can be effectively disposed to avoid the production of a wasteful space, thereby providing reductions in size, weight and cost.Type: GrantFiled: September 1, 1998Date of Patent: May 30, 2000Assignees: Sawafuji Electric Co., Ltd, Honda Giken Kogyo Kabushiki KaishaInventors: Masahiro Fukuda, Toru Nishikura, Masaru Sakamoto, Akira Fukuda, Takao Tamechika, Tsutomu Hatsugai

Patent number: 4993256Abstract: In order to accurately conduct a leakage test in a short time, an initial pressure higher than a test pressure is first supplied into a hollow object to be tested. Then, part of the pressure within the object is relieved to decrease the temperature within the object to the ambient temperature so that the pressure within the object can be stabilized at the test pressure. Then, a variation in the pressure within the object is detected to determine whether there is any leakage in the object. In the case where a negative pressure is utilized, an initial pressure lower than the test pressure is first supplied into the object, and then part of the pressure within the object is relieved by introducing the ambient air into the object, to increase the temperature within the object to the ambient temperature so that the pressure within the object can be stabilized at the test pressure. Then, a variation in the pressure within the object is detected to determine whether there is any leakage in the object.Type: GrantFiled: April 19, 1989Date of Patent: February 19, 1991Assignee: Kabushiki Kaisha FukudaInventor: Akira Fukuda

Patent number: 4802632Abstract: A device and method for treating the end portion of a paper from a paper roll mounted on a paper feed unit of a paper processer. The device arranged adjacent the paper roll is moved toward the paper roll until a presser roller mounted on the device is pressed against it. A cutter assembly facing the paper roll is pushed out so that its cutter will come into contact with the periphery of the paper roll. The cutter is then slid transversely from one end of the paper roll to the other to cut several turns of paper from the paper roll as broke. The broke is rolled out to be fed downwardly over a suction body through a pair of nip rollers and taken up by a take-up mechanism. Another cutter assembly is pushed forward into contact with the central part of the paper end rolled out together with the broke and moved widthwise to make a center cut in the paper end. A cavity forming device is then pressed against the paper end right under the center cut to form a square cavity there.Type: GrantFiled: March 2, 1988Date of Patent: February 7, 1989Assignee: Hamada Printing Press Mfg. Co., Ltd.Inventors: Akira Fukuda, Itsuro Masuda
