Title: Rotor for motor
Inventor: FUTAMI TOSHIHIKO
IPC: H02K1/27
Filed: 1998-09-09
Abstract: PROBLEM TO BE SOLVED: To prevent damage due to the melting and deterioration of plastics constituting a bonded magnet even when a shaft is shrinkage-fitted under the state, in which the bonded magnet is formed beforehand on the outer circumference of a core. SOLUTION: The rotor for the motor has a columnar core 1 having a central hole 2, into which a shaft is fitted, and a cylindrical plastic bonded magnet 3 integrally formed on the outer circumference of the core 1. The core 1 has structure, in which a section between an internal layer section 7 on the central hole 2 and an external layer section 8 on the bonded magnet 3 is connected by a plurality of bridging sections 9 arranged at intervals in the circumferential direction. When the core 1 is heated from the central hole 2 for shrinkage-fitting the shaft, heat transfer from the internal layer section 7 of the core 1 to the external layer section 8 is decreased because thermal resistance is increased by the reduction of sectional areas in the bridging sections 9 in the core and the temperature rise of the bonded magnet 3 is inhibited.

Title: Photomask
Inventor: KOSHIDA HARUTAKA
IPC: G03F1/70
Filed: 1991-10-03
Abstract: PURPOSE:To prevent the ends of chromium patterns from picking up thin dust at the time of substrate washing by eliminating the level difference of the patterns stuck onto a glass substrate. CONSTITUTION:The chromium pattern 2 is embedded into the glass substrate 1 in such a manner that the respective front surfaces thereof are flush with each other. Since the chromium pattern 2 is embedded in the glass substrate 1 flush with each other at the front surfaces, there are no level differences on the pattern surface of the mask. The pickup of the thin dust at the end of the chromium pattern 2 and the consequent wear and peel of the chromium pattern 2 are prevented in this way at the time of washing the photomask. The chromium pattern 2 is completely taken into the glass substrate 1 and the coating of the front surface fully with glass is possible as well. The material quality of the pattern surface is uniformized in such a manner and since the state of the substrate surface is uniformized, the surface tension of a washing liquid is constant and the wettability of the substrate surface with the liquid is constant. The pickup of the dust does not arise.

Title: Image forming device
Inventor: NISHIKINO SACHIKO
IPC: G03G15/02
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To obtain a satisfactory image until the prescribed time of maintenance and to prevent a condition allowing image formation from being brought into a standby condition due to the cleaning of a corona discharger. SOLUTION: The device is equipped with a controller 50 for actuating, right before a preheat mode, a cleaning means which cleans a discharge wire 25 by moving a cleaner hold plate 45 along the discharge wire 25 by the rotation of a motor 41. Because the discharge wire 25 is cleaned by the cleaning means right before the preheat mode irrespective of the number of times that images are formed, an image forming operation is prevented from being suspended as a result that the condition allowing image formation has been brought into a suspended condition. Therefore, efficient image formation can be carried out. Further, it is preferable that the cleaning means be actuated when the temperature of a fixing part is below a specific temperature, and after 24 or more hours have elapsed after the previous cleaning operation by the cleaning means.

Title: Tool failure detector
Inventor: TAKINAMI KOJI
IPC: G01N29/14
Filed: 1984-12-05
Abstract: PURPOSE:To detect the wear of a tool by applying once the signal obtd. from an AE sensor to a signal pre-processing part, determining the probability density function of the output of the AE sensor and transmitting a signal when the max. density thereof exceeds a prescribed level. CONSTITUTION:The AE signal is converted to digital data at a prescribed sampling period via a BPF21 and an A/D conversion circuit 23 and is once stored successively into a memory. The probability density function is calculated in accordance with the data and the max. value thereof is determined. The tool is not so much worn when the max. value does not exceed the threshold level Th. The similar processing is therefore repeated and a gate open signal is applied to a gate circuit 25 to end the processing when the max. value exceeds the value Th. The signal of the AE sensor is transmitted to the signal processing part only when the wear of the tool exceeds the prescribed extent and therefore the processing in the signal processing part is made easy. The load is thus decreased and the reliability of the failure detection is improved.
