Title: Original position detector
Inventor: MURAI TOSHIHARU
IPC: G01B11/00
Filed: 1997-12-10
Abstract: PROBLEM TO BE SOLVED: To detect the size of an original and the original position on an original platen even in the case an original sheet is deep in color and a high-density image lies all over the original, besides, to detect the original end on the original platen even in the following cases; the original sheet is larger in size than the original platen, one end of the original lies away from an original placing reference end position and reflected light is not appropriately obtained, due to diffused external light. SOLUTION: The position of the original on the original platen and the size of the original are detected by receiving the reflected light of scanning light emitted from an irradiator 21 by a light receiving device 28, discriminating between the reflected light from an original pressure plate among the received reflected light and the reflected light from other originals by a light receiving circuit 43 in relation to the scanning light and the position on the original platen, and also, discriminating and detecting the received light from the diffused external light by a reflected light detection circuit 44.  Besides, in the case the original is larger in size than the original platen, and in the case one end of the original lies away from the original placing reference end position, the position of the original is detected based on the position of the scanning light and the diffused external light receiving position.

Title: Pressure fixing toner
Inventor: TSUJIHIRO MASAKI
IPC: G03G9/087
Filed: 1992-11-27
Abstract: PURPOSE:To prevent the contamination at the interior of a developing part, a photosensitive body, etc., and to attain a sharp distribution of the amt. of electric charges by using a resin matrix phase and a viscous solid domain phase having a lower glass transition temp. than the matrix phase and contained in the matrix phase. CONSTITUTION:This toner 1 consists of a resin matrix phase 3 and a viscous solid domain phase 2 having a lower glass transition temp. than the matrix phase 3. The matrix phase 3 is preferably made of a polymer obtd. by dispersion-polymerizing a first monomer and the domain phase 2 is preferably made of a polymer obtd. by polymerizing a second monomer mixed in the matrix phase 3. Since the domain phase 2 is a viscous solid having a glass transition temp. lower than the matrix phase 3, even when the matrix phase 3 cracks, the internal domain phase 2 does not contaminate the interior of a developing part or a photosensitive body. The viscous solid domain phase 2 can ensure the tight fixation on a base.

Title: Gas compressor
Inventor: KUMAKURA YASUHIDE
IPC: F04C18/344
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide a gas compressor superior in the low-noise characteristic and wear resistance, effectively preventing wear and noises at the vane tip due to increase in the contact surface pressure of the vane tip, and noise due to the direct impact of high-pressure refrigerant gas on the casing. SOLUTION: In order to avoid the contacting length between the vane tip and cylinder inner wall is reduced temporarily while the vane tip moves along the inner wall of a cylinder 1, a side discharge hole 31 is disposed in a side block 3 on the rear side. High-pressure refrigerant gas is thereby discharged from the compression chamber to a discharge chamber 14 through the side discharge hole 31. In this structure, a conventional cylinder discharge hole which is disposed open on the moving route of the vane tip on the inner wall of the cylinder 1 is thus abolished.

Title: Fine particle behavior pattern
Inventor: SASAKI TAKASHI
IPC: B01J19/12
Filed: 1990-12-13
Abstract: PURPOSE:To control the fine particle behavior in a specified pattern and to fixe, process and modify the fine particle by repeatedly scanning the focus position of a laser beam at a high rate and capturing the fine particles on the track to form a pattern. CONSTITUTION:A trapping laser beam is biaxially polarized with two galvanomirrors 2 and matched with the numerical aperture and focus position of a microscopic optical system with two lens systems 3. The beams are reflected by a dichroic mirror 4 in the microscope and condensed on a sample with an oil immersion lens 5. The laser beam is repeatedly scanned at a rate sufficiently higher than the mechanical speed of response determined by the diameter of the particle and the viscosity of the medium, hence each particle is trapped just the same as the particle being captured by stationary light, and many particles are captured on the track of the focus. Accordingly, the behavior of the particle is controlled in a specified pattern, and the particle is processed and modified.
