Title: Graphic expressing method and graphic displaying method
Inventor: MATSUDA MASAYUKI
IPC: G06T1/00
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To execute graphic processing such as rotation and moving with high calculating precision with respect to an expressed and displayed graphic by always positioning the center of the graphic on a pixel in the case of expressing and displaying the graphic as the set of pixels. SOLUTION: The center point of a first square 10 whose length of one edge is odd times (three times) as long as a pixel is positioned on a pixel added with number 14. Consequently, since the center of the graphic is positioned on the pixel at the first square 10, it is never deviated by the portion of a single pixel as against a second square 12 in spite of executing graphic processing such as rotation by 180 deg.. As the result, it is possible to execute graphic processing of improved precision.

Filed: 1999-09-01
Abstract: PROBLEM TO BE SOLVED: To attain the correct offset cancelling adjustment. SOLUTION: A printed-circuit board 3 to be adjusted is arranged on a test bed 4, and probe pins 5 electrically connected to signal lines from photodetectors of a pickup module 10 are connected to signal lines of the printed-circuit board 3 to be adjusted.

Title: Device for recovering oil in catch basin
Inventor: KUBO TAKAAKI
IPC: C02F1/40
Filed: 1988-09-30
Abstract: PURPOSE:To continuously recover oil without attendance by constituting the device of a specific guide rail, float type skimming pipes, an oil storage pipe and a freely extendable/contractable oil suction pipe. CONSTITUTION:After the guide rail is assembled, ballast water is injected into the float pipes 2 and the skimming pipe 1 is held half submerged in water. The height of a suction port is then finely adjusted by an adjusting ring 44 and is so set that the oil 8 is efficiently sucked. An inside pipe 42 is pulled up form an outside pipe 41 in follow up to the rise of the float pipes 2 and the extension/contraction pipe 42 extends as well when the device is once set and when the float pipes 2 are risen by, for example, the rise of a water level. The skimming pipe 1 is thus positioned always at the specified height with the water surface and the operation of recovering the oil 8 is continuously executed without attendance. Since the skimming pipe 1 recovers oil by the slit opened over the entire length, the oil 8 on the water surface can be recovered linearly over a wide range. Further, the storage pipe 3 is freely extendably and contractably connected to the float parts and the recovered oil-contg. water is stored in the storage pipe 3 through the suction pipe 4.

IPC: C04B35/58
Filed: 1991-09-26
Abstract: PURPOSE:To obtain sintered zirconium boride having high density and excellent hardness and toughness by sintering anisotropic crystal particles of zirconium boride to raise the relative density above a specific level. CONSTITUTION:The objective sintered ZrB2 consists of sintered anisotropic crystal particles and has a relative density of >=90%.

The product is composed of >=70wt.% of ZrB2 consisting of sintered anisotropic crystal particles and <30wt.% of ZrC and has a relative density of >=90%. Since the sintered compact is free from metals such as Cr and Ni, it has high hardness and excellent high-temperature mechanical properties and is resistant to corrosion by seawater and molten metal such as Al. The propagation of crack is suppressed by the presence of the sintered anisotropic crystal particles to increase the toughness.

IPC: G03G15/00
Filed: 1986-10-17
Abstract: PURPOSE:To incorporate such a system that misaligned copying sheets are not taken into copy count by furnishing the copying machine with a sensor to sense copying sheet transported to a specific position. a timer, a timing judging means, and a count stop means. CONSTITUTION:Each copying sheet is as primary feed transported from a cassette 4 to a timing roller 5 to be further sent to a transcript part 7 in timing with rotation of a photo-sensitive drum 6. The copying sheet with toner image transcripted thereon at the transcript, part 7 is transported to a fixation part 9 via a transport part 8. A check switch 10 is furnished in a specific position of the transport part 8 to enable sensing whether the copying sheet has been transported till this position. Because the transport speed of the copying sheet is constant, the time from the roller 5 to reaching the specified point on the downstream side about transportation is constant. Accordingly comparison of the actually counted transport time with the transport time in normal case should provide sensing of the dislocation of copied image. In this case, no count-in is made into the copy count, so that the desired number of normal copies will be obtained.

Title: Abnormality sensor, and device and system for abnormality detection
Inventor: KAWAMATA MASAMI
IPC: G08B23/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality detection device which is easily installed, can detect the occurrence of abnormality without contact and also can be repetitively used, when a light emitter is replaced after the detection of abnormality by using a pawl member which is actuated by the state change of a detection object and the light emitter which emits the light when it is depressed by the pawl member. SOLUTION: A light emitter 1 is fixed to a casing 6 of a sensor main body via an upper cover 5, and a water-absorbing sheet 7 is used to prevent a water absorbing swelling member 3 from leaking to a water-absorbing port 4. A pawl member 2 can move upward by the swelling of the member 3. When an inundation phenomenon occurs, the water enters through the port 4 and reaches the member 3 through the sheet 7. The member 3 can swell only in the upper direction, and accordingly the member 3 swelled by the water pushes up the member 2 and bends the light emitter 1 to make it emit light and to detect the inundation phenomenon. Furthermore, this abnormality sensor itself can be used repetitively, when the member 3 and the light emitter 1 are replaced with new ones respectively, after the inundation phenomenon has been detected.
