Title: Faraday rotator
Inventor: ISHIKURA KENJI
IPC: H01F1/34
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a method for reducing magnetic hysteresis and identifying easily and magnitude of the magnetic hysteresis in a bismuth-substituted rare- earth iron garnet single-crystal film having very low saturation magnetic field but hardly used as a photoswitch or a Faraday rotator for a magnetic field sensor because of its higher magnetic hysteresis. SOLUTION: A bismuth-substituted rare-earth garnet single crystal is grown in such a state that five or more pits remain in a Faraday rotator when the Faraday rotator is formed by cutting the bismuth-substituted rare-earth garnet single crystal. Then, the magnetic hysteresis is reduced in the bismuth-substituted rare-earth garnet single crystal that has been hardly used as an optical switch or a Faraday rotator for a field sensor, and at the same time a Faraday rotator with large magnetic hystreresis can be identified easily. Then, the bismuth- substituted rare-earth garnet single crystal with low saturation magnetization can be utilized as a Faraday rotator for an optical field sensor.

Title: Solid-state image sensing device
Inventor: HAMAZAKI MASAHARU
IPC: H04N5/335
Filed: 1988-09-20
Abstract: PURPOSE:To dimensionally reduce protective circuit itself by protecting an internal circuit from an over-input by forward currents when a junction between semiconductor regions is forwardly biased and by using punch-through when the junction is reversely biased. CONSTITUTION:A p-type well region 2 as a second conductivity type semiconductor region is shaped to an n-type silicon substrate 1 as a first conductivity type semiconductor base body. An n<+> type semiconductor region 3, a first conductivity type semiconductor region, is formed in the well region 2, facing the main surface of the well region 2. When over-input voltage at low potential is applied to the P terminal 4 side between a P terminal 4 and an L terminal 6, a p-n junction between the region 3 and the region 2 is forwardly biased, and forward currents are made to flow by the junction and an internal circuit can be protected. When over-input voltage at a high potential is applied to the P terminal 4 side, the p-n junction between the region 3 and the region 2 is reversely biased. Accordingly, punch-through is generated between the substrate 1 and the semiconductor region 3, thus protecting the internal circuit from an over-input.

Abstract: PURPOSE:To prevent generation of soil of a recording material or the like by changing a peak position of the distribution of abutment pressure of a cleaning web or abutment position of the cleaning web against the surface of a fixing means to the moving direction of the surface before starting the fixing operation. CONSTITUTION:Peak position of the distribution of abutment pressure of a cleaning web 7 or abutment position of the cleaning web 7 against the surface of a fixing means (fixing roller) 1 is changed to the moving direction of the surface by moving a presser means (presser roller) 8 before starting the fixing operation. In the case that residual toner exists at the peak position or the abutment position, pressure of the cleaning web 7 to the toner is cancelled once to move the toner smoothly. When the fixing means 1 is driven under this condition, the residual toner is moved on the surface of the fixing means 1, and is moved securely. Even in the case that the residual toner exists with a large quantity of offset, the residual toner is eliminated to prevent generation of soil of the recording material and a pressurizing roller 4.

Title: Optical refraction device
Inventor: IDE YUJI
IPC: H04N5/349
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To attain high resolution by using attracting and repulsion force of a ring magnet so as to position an optical refraction section so as to differentiating counter optical axis angles with the repulsion force thereby moving minutely a formed image and reading an image signal at each position. SOLUTION: The optical refraction section 2 is formed by arranging an optical refraction mechanism between a lens and an image pickup element and forming a coil around an optical refraction member such as glass. The optical refraction section 2 is moved in an optical axis direction in a housing 5 of a ring magnet 6 and attracted or repulsed to/with the magnet 6 depending on the direction of a current to the coil and in contact with a face of the housing 5. The glass of the optical refraction section 2 has an angular difference with the optical axis between two positions, a length depending on the thickness of glass, refraction and angular difference is an image forming moving distance on the image pickup element and the moving direction is a direction causing the angular difference. Thus, the accuracy of moving distance and direction is easily taken. Furthermore, the position of the optical refraction section 2 depends on the direction of a current supplied to the coil, and is formed by inexpensive components such as glass, magnet and housing and then the cost is reduced.
