A disk drive comprises a cartridge holding mechanism which has a small size and reduces a damper load. The disk drive comprises: a spindle motor 91 which mounts and rotates a disk; a traverse base 82 which holds the spindle motor 91; a rubber damper 71 which flexibly holds the traverse base 82; a mechanical chassis 60 which holds the traverse base 82 through the rubber damper 71; a tray 20 which mounts a cartridge 1 in which a disk is housed; and a loading motor 61 which moves the disk in the cartridge 1 close to the spindle motor 91 or away from the spindle motor 91. The cartridge 1 is supported by the mechanical chassis 60 through the tray 20.

In an attachment structure for attaching an attached-plate to a printed substrate which is installed in a mechanical chassis, the mechanical chassis includes a positioning pin for positioning the printed substrate; and the attached-plate includes a guide groove that engages with the positioning pin and is slidably guided in a predetermined path, a fixing portion to the printed substrate, and an engaging portion that engages with a side portion of the printed substrate. By causing the attached-plate to slide along a substrate side of the printed substrate with the guide groove being engaged with the positioning pin, the guide groove is guided by the positioning pin, whereby the engaging portion engages with the side portion of the printed substrate. In the engagement state, by fixing the fixing portion of the attached-plate to the printed substrate, the attached-plate is attached to the printed substrate.

A constant voltage circuit robust to the input voltage lowering is disclosed. The invention is applied to a constant voltage circuit fed with an input voltage through first and second power conductors for transferring the input voltage to a load as an output voltage through an output transistor. An inventive constant voltage circuit is provided with a substitute circuit, responsive to a detection of the lowing of the input voltage to a predetermined voltage, for providing a substitute output path that is connected in parallel with the output transistor. Doing this minimize the degree of lowering of the second voltage due to the lowering of said first voltage. The output transistor may be nay of NPN and PNP transistors and P-type and N-type MOS FETs.

In a driving apparatus for piezo-stacks, a controller repeats switching operation for turning switching elements on/off to thereby attain a determined piezo-actuator voltage. An abnormality detecting circuit determines abnormality of the piezo-stacks by comparing the number of times of charging and the number of times of discharging, or charging/discharging time periods at this occasion with those at normal time.

To prevent a great variation of a detected wheel velocity for a period of time after a front wheel sensor or a rear wheel sensor for detection of a wheel velocity actually fails until a microcomputer detects the failure, it is determined whether or not an output pulse period of a front wheel sensor is equal to or shorter than a predetermined period. When the output pulse period exceeds the predetermined period, it is determined that there is the possibility that the front wheel sensor may be in failure, thus a front wheel velocity for a predetermined number of control cycles before, or a front wheel velocity before the failure, is adopted as a front wheel velocity of the present control cycle. Also, a rear wheel velocity is calculated in a similar manner. For a time after a failure actually occurs until the failure is detected by a microcomputer, driving force control is not started even if other starting conditions for driving force control are satisfied.

The present invention provides a method for evaluating lithographic characteristics of a lithographic composition containing a copolymer for lithography without actually preparing the composition. The method comprises the steps of: dissolving the copolymer for lithography in a solvent to prepare a test solution; separating a gel-like substance from the test solution; determining a rate of change of a composition ratio, wherein the rate of change of the composition ratio rate refers to a ratio of a difference obtained by subtracting a composition ratio of constitutional units in the copolymer for lithography from a composition ratio of constitutional units in a gel-like substance to the composition ratio of the constitutional units in the copolymer for lithography.
