Inventor: TERAJIMA ATSURO
IPC: C07H15/252
Filed: 1985-12-13
Abstract: NEW MATERIAL:The 13-methyl-13-dihydro-4-demethoxydaunomycin derivative of formula I (R is H or trialkylsilyl). EXAMPLE:13-Methyl-13-dihydro-7-O-t-butyldimethylsilyl-4-demethoxydauno mycin.

Title: Read-out data resynchronizing device
Inventor: HASEGAWA SEIJI
IPC: G11B20/14
Filed: 1989-10-26
Abstract: PURPOSE:To constitute the device so that data can be read even in the case the synchronization is lost by storing successively a prescribed bit, selecting a prescribed bit of a part thereof, and changing a selected bit so that an error is not generated at the time of processing the selected bit. CONSTITUTION:In the case the synchronization is lost, sometimes data of a group in which at least one of 5 bits of an address 5 to 9 is different is placed. In such a case, a 5-4 converting circuit 3 cannot be converted by a correct delimiter, therefore, a 5-4 error is generated. When the 5-4 error is inputted from the circuit 3, an address controller 4 outputs a control signal of 4 bits to a data selector 2, and change a selected bit address of the selector 2 to the upper rank or the lower rank. When the synchronization is taken, data of a new address becomes data of the upper 5 bits or the lower 5 bits in one byte of a prescribed group, and the 5-4 error is not outputted. In such a way, in the case the synchronization is lost, the synchronization is restored before the next synchronizing signal is generated, and data can be read.

Title: Axial blower
Inventor: TAKEUCHI KAZUHIRO
IPC: F04D29/38
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent the cascade interference caused by the extreme inequality of blade intervals. SOLUTION: Inter-blade pitch angles P1 , P2 of fan blades 9a-9c differ, and the inter-blade pitch angle P1 is made larger than the inter-blade pitch angle P2 . As the inter-blade pitch angle is made smaller, the backwash by the fan blade located at the front in the rotating direction easily collides with the fan blade located at the rear in the rotating direction. The interval in the drive shaft direction between the fan blade 9a having the smaller inter-blade pitch angle and the fan blade 9b is increased, and the interval in the drive shaft direction between the fan blade 9b having the larger inter-blade pitch angle and the fan blade 9c is decreased.

Title: Polarized light converter and illuminator using it
Inventor: IMAOKA HIROFUMI
IPC: H04N5/74
Filed: 1997-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a constitution by which a uniform illuminance distribution can be obtained with a high optical efficiency in a polarized light illuminator applied to a projection type display device. SOLUTION: A polarized light converter is arranged between a 1st lens board 11 and a 2nd lens board 15 corresponding to integrator. The polarized light converter separates each focused light flux of light of a light source obtained from each lens segment 11a of the 1st lens board 11 into different linearly polarized light through a polarized light separation prism board 12, and converts one of the linearly polarized light into the same polarized light as the other one through a λ/2-wave plate 13 for letting the two systems emit, however, a glass block 14 for correction is provided in a longer optical path.  Since the glass block 14 for correction corrects an image formation position of the focused light flux and the focusing condition, and makes the focused light fluxes of the two systems incident on each lens segment 16a of the 2nd lens board 15 under the same condition, it is possible to accurately superpose each secondary light source image on an illumination area for forming an image.

Title: Magnetic circuit for magnetic levitation using permanent magnet
Inventor: OHASHI TAKESHI
IPC: H01F7/02
Filed: 1990-10-19
Abstract: PURPOSE:To increase an attraction force of a permanent magnet by multipolarizing the magnet and by making the magnetized areas of the N pole and S pole on the surface of the magnet nearly the same. CONSTITUTION:A permanent magnet attached firmly to a movable body is multipolarized to lower the average demagnetizing field while making a working point high. By multipolarization of the magnet, the demagnetizing field of each magnetic pole is reduced. However, if the number of poles is increased more than necessary, a magnetic transition region between the poles expands, causing a decline of an attraction force of the magnet since the magnetic transition region between the poles does not exert attraction. The required number of poles is not less than two but not more than 20. Preferablly, not less than three but not more than 10. In order to obtain the maximum attraction force of the magnet, it is important that the magnetized areas of the N pole and S pole on the surface of the permanent magnet are nearly the same.
