Disclosed is the invention in connection with an electric sewing machine comprising a machine body 1 and a controller 2, wherein the controller 2 is responsive to a first press to produce a signal for starting the machine body 1 and is responsive to further press to produce a signal for driving the machine body 1 at a stitching speed (drive speed) in accordance with the pressing amount. The machine body 1 is provided with a control device 11 which is connected to a changing device 30 which is operated to change the control content of the control device 11. The changing device 30 may be operated to switch the control device 11 between being operative and being inoperative. In case the control device 11 is switched to being inoperative, the control device 11 neglects the instruction signal from the controller 2, for example, produces a stop signal to a motor drive device 12 in response to a machine drive signal from the controller 2, thereby to maintain the machine motor as stopped. Therefore, if the changing device 30 is selectively operated beforehand to switch the controller 11 to being inoperative, the machine body 1 will not driven in response to the instruction signal from the controller 11 which may be wrong operated. Thus the safety may be secured.

A ship has a main propeller 2 which can move the ship forward and reverse by normal rotation, reverse rotation or by changing the pitch angle. A drive unit drives the main propeller 2. A rudder 3 changes the course of the ship. At least one pod propulsion unit 10A, 10B is provided. As a result, the support mechanism and the turning mechanism of the pod propulsion unit, arranged separate from the main propeller, can be simplified and cost can be reduced.

The toner supply roller 31 includes a roller shaft 31A made of metal, an inner spongy member 31B formed around the roller shaft 31A, and an outer spongy member 31C formed around the inner spongy member 31B. The inner spongy member 31B is formed of a closed cell foam material having electrically conductive properties. On the other hand, the outer spongy member 31C is formed of an open cell foam material having electrically conductive properties. Therefore, toner particles will not enter the cells formed in the inner spongy member 31B even after the toner supply roller 31 has been used for a long time.
摘要:
A process for preparing an optically active mercapto compound having asymmetrical centers having the formula: ##STR1## in which R.sub.1 represents an alkyl group, R represents a hydrogen atom or an alkyl group, C* represents an asymmetric carbon, n represents the value of 1 or 2, is disclosed. The process involves the reaction of a cultured microorganism having the ability of asymmetrically hydrolyzing ester bonds of the raw material, thus eliminating the need for protecting free mercapto groups which are unstable in the reaction conditions. The optically active mercapto compound is useful as a raw material for producing a compound having medicinal effects such as antihypertensive activity.

To facilitate replacing photosensitive drums and/or developing devices in an image forming apparatus, a photosensitive member unit including a plurality of photosensitive members is loaded in a main casing. A developing device unit including a plurality of developing devices is also loaded in the main casing. Both an intermediate transfer belt and the photosensitive member unit are configured to be movable toward and away from the developing device unit. Further, when the photosensitive member unit is separated from the developing device unit, the intermediate transfer belt and the plurality of photosensitive members are also separated from each other.

A cartridge includes an engagement gear which includes a first engaging portion and is configured to selectively rotate. The cartridge also includes a rotational body which includes a second engaging portion, and a center axis of the rotational body is aligned with a center axis of the engagement gear. Moreover, the cartridge includes an extension portion which is positioned offset from a center of rotation of the rotational body. The engagement gear and the rotational body are configured to selectively be positioned in one of a first state in which the second engaging portion and the first engaging portion are separated from each other, and a second state in which the second engaging portion engages the first engaging portion. The rotational body is configured to rotate with the engagement gear when the engagement gear rotates and the engagement gear and the rotational body are in the second state.

An image forming device according to an aspect includes: a main body; and a first cartridge configured to accommodate a developer and detachably attached to the main body. The first cartridge includes: a rotation body rotatably provided in the first cartridge; a memory device configured to store information concerning the first cartridge; and a first terminal electrically connected to the memory device. The main body includes: a driver configured to rotate the rotation body; and a second terminal electrically connected to the first terminal. The first terminal is provided at a position where a torque produced by rotation of the rotation body acts in the first cartridge.
