A defect inspection apparatus enable to efficiently perform a temperature control without involving an enlarged size can be achieved. Using the method, catalog information including a still picture and additional information together with audio data are recorded on a storage medium such as a digital versatile disk, which is an optical record storage medium, and the catalog information is played back during playback of the audio data, to thereby provide various information on the audio data. Further disclosed are novel methods of introducing phosphorus-containing moieties such as phosphate moieties to compounds having glycerolic backbone and intermediates formed thereby. The most commonly used inhibitors of the mineralocorticoid receptor are precursors of canrenone. In addition, the unit can dampen the movement of the drive shaft.
