A lens driving device includes a lens holder that holds a lens, a driving portion that drives the lens holder through a magnetic force produced using a coil and a magnet, and a guide shaft that supports the lens holder movably. When moving the lens holder to a target position, an AC voltage is applied to the coil over a specific interval from a beginning of movement of the lens holder. Further, an amplitude of the AC voltage is reduced stepwise with the passage of time.

Lens driving device and optical pickup

Agents for improving potency of the urinary bladder which comprise an amine compound of non-carbamate-type having an acetylcholinesterase-inhibiting action. Particularly, crystals of a tricyclic, condensed, heterocyclic derivative are provided, which possess an excellent action to inhibit acetylcholinesterase and an action to improve the excretory potency of the urinary bladder. As an example, crystals of 8-[3-[1-[(3-fluorophenyl)-methyl]-4-piperidinyl]-1-oxopropyl]-1,2,5,6-tetrahydro-4H-pyrrolo[3,2,1-ij]quinolin-4-one or a salt thereof and pharmaceutical compositions containing them are disclosed.

Agents and crystals for improving excretory potency of urinary bladder

An optical disc recorder that records information on an optical disc by means of a laser diode that forms pits in the optical disc through the application of a write pulse of a previously set type, the recorder having a reference power setter that sets a reference power that is the reference value of a drive power of the write pulse, a pulse type checker that checks whether the type of write pulse set consists of a plurality of pulses, which allows the drive power to be set for each pulse of a plurality of pulses, a power corrector for correcting the drive power of at least one pulse of the write pulse by adding a previously set correction power to the reference power, and a drive controller that applies the write pulse, which consists of the pulse with the reference power and the at least one pulse with the drive power corrected.

Optical disc recording apparatus

The present invention provides a compound represented by the formula or salts thereof, wherein, Ar, Ar, R, R, R, Ra, Ra, Ra, Raand Y have meanings described in the specification, having a melanin-concentrating hormone antagonistic, action and useful as an agent for the prophylaxis or treatment of obesity and the like.

Amine derivative

Preventives/remedies for voiding disturbance containing a compound having both of an acetylcholinesterase inhibitory action and an &#x3b1;1 antagonistic action which exhibits an excellent effect of improving the urinary function of the bladder (i.e., effects of improving urine flow rate and voiding efficiency) without affecting the urinary pressure or the blood pressure.

Preventives/remedies for urinary disturbance
