Inventor: HAYASHI KUNIO
IPC: H02K5/00
Filed: 1995-01-27
Abstract: PURPOSE: To obtain a scanner motor for driving a polygon mirror in which a stabilized rotation can be obtained constantly by reducing the gap between the fitting hole of polygon mirror and the part to be fitted of a mirror fixing member to the utmost. CONSTITUTION: A slot 49 is made in the upper surface at the fitting protrusion 44 of a mirror fixing member 41 being fitted in the fitting hole 46 of a polygon mirror 45 and a resiliently deformable part 50 is provided on the outside of the slot 49. When an enlarging screw 52, also serving as the fixing screw of a mirror stopper 51, is driven into a screw hole 48 made in the upper surface at the fitting protrusion 44, the resiliently deformable part 50 is pushed outward to be pressed against the fitting hole 46 of the polygon mirror 45. Consequently, the gap can be eliminated substantially at the part 47 where the fitting protrusion 44 is fitted in the fitting hole 46 of the polygon mirror 45.

Abstract: PURPOSE:To obtain the accurate output, by connecting a light quantity compensating circuit in parallel with a signal detecting circuit part, providing 4 pattern tracks in fixed disks, detecting 4 signals, performing differential amplification, and making the DC component of the output voltage zero. CONSTITUTION:Photodetecting elements 9a-9d receive the light beams, which have passed first - fourth pattern tracks of fixed disks, and generate outputs having phase difference of every 90 deg.. The outputs having the phase difference of 180 deg. to each other are imparted to differential amplifiers 12a and 12b, and the outputs, which do not include DC components, are obtained. A light quantity compensating photodetecting element 13 directly receives the light from a light source 3 and is connected to the photodetecting elements 9a-9d in parallel. A voltage from a power source is applied across the element 13, and a current corresponding to the quantity of the received light is made to flow. The current is converted into a voltage by a variable resistor 14. The voltage is applied to the base of a transistor 16, which is connected to the light source 3 through an operation amplifier 15 in series, as an output voltage of the light quantity compensating photodetecting element 13. Thus the quantity of light is compensated.

Title: Soft polyester fabric and its production
Inventor: HARA TOSHINORI
IPC: D06M101/16
Filed: 1995-01-27
Abstract: PURPOSE:To produce the subject fabric having soft feeling by allowing to remain a very small amount of a decomposition product of a sizing agent which is applied to a polyester fabric dyed with a disperse dye when the sizing agent is removed with an enzyme after a shapesetting process. CONSTITUTION:A sizing agent preferably having excellent biodegradability (e.g. starches, processed starches, proteins, etc.) is applied on a polyester fabric before shape-setting process. The fabric is subjected to the shape-setting process at 150-220 deg.C and subsequently the sizing agent is removed with an enzyme. The decomposition product is allowed to remain on the surface of the fabric in such a degree that the difference in brightness of color DELTAL before and after silver mirror reaction is >=0.1 and <=5.0. This method enables the formation of a polyester fabric having soft feeling and excellent in water absorption properties and the touch by increasing space between fibers in the same degree as that of an alkali thinning process, without using such a process as to make the fiber brittle.
