Abstract: A microorganism of the genus Rhodococcus is provided which has a higher sensitivity to lysozyme at a low concentration than a wild-type strain, which can easily cause cell lysis, and from which a recombinant protein expressed therein is easily recovered. More specifically, a mutant microorganism of the genus Rhodococcus having a higher sensitivity to lysozyme than a wild-type microorganism of the genus Rhodococcus.

Abstract: A washable electric shaver apparatus an outer blade frame of which is mounted on the top of the shaver so as to be movable by a limited distance away in parallel from the top of an outer casing in response to the depression of a pair of releasable push buttons mounted on opposite sides of the outer casing. A gap is formed between the outer blade frame and the top of the outer casing as a result of such movement of the outer blade frame relative to the outer casing, so that shavings accumulated around an inner blade member can completely be removed away through the gap when washing the shaver in water.

Abstract: An electric shaver is described which comprises: a housing; a fixed cutter mounted to the housing; and a movable cutter arranged to slide along the fixed cutter. A driving motor is linked to the movable cutter for slidably moving the movable cutter along the fixed cutter. A power supply circuit is electrically connected to the driving motor for supplying a selectively controllable voltage to the driving motor. The power supply circuit comprises a charging circuit and a control circuit. The charging circuit includes a voltage reducing transformer, and a rectifying element and a rechargeable battery connected in series with the secondary coil of the voltage reducing transformer. The control circuit is connected to the driving motor in parallel to the rechargeable battery. The control circuit includes a starting switch and at least one voltage drop element having a substantially constant voltage characteristic. The starting switch and the voltage drop element are connected in series with the driving motor.
