The depsipeptides have an activity of promoting the production of apolipoprotein E and are useful as a therapeutic agent for neurologic damages, especially for dementia, and further as a therapeutic agent for hyperlipemia.
摘要:
An image processing method and apparatus which makes possible image processing based on attribute specification contents specified by an attribute specification image by reading an original including an original image and the attribute specification image which specifies the contents of processings to be performed on the original image.A scanner reads a format original containing bar codes indicating data attribute specifications such as character limit range, character color, etc. The read bar code patterns are analyzed and the attribute specification data such as character limit range, character color, etc. is stored in RAM once. Then, the original to be output is read and stored in RAM as image data. Processings (such as color conversion, etc.) corresponding to the aforementioned attribute specification data are performed in relation to this image data. After all of the processings specified by the attribute specification data has been carried out in relation to this image data, the resulting data is printed onto a printer.

A swash plate tiltably supported on a drive shaft is controlled by adjusting the pressure in a crank chamber. When an electromagnetic valve is de-excited, the high-pressure refrigerant gas in a discharge chamber is supplied to the crank chamber so that the inclination angle of the swash plate is shifted to its minimum inclination from its maximum inclination. An open/close mechanism located in a suction passage gradually opens or closes the suction passage in accordance with the differential pressure between the pressure in the external refrigeration circuit located upstream the open/close mechanism and the pressure in a suction chamber. When the inclination angle of the swash plate is minimized, the open/close mechanism closes the suction passage. It is therefore possible to prevent frosting while also suppressing rapid changes in load torque.

An image forming apparatus for forming a color image on a recording material includes mounting means for detachably mounting a plurality of process cartridges each including a photosensitive drum and a developing roller. Movable members are provided that are actable on first and second clutches for switching between an operation state for transmitting the driving force to the developing rollers and a non-operation state not transmitting the driving force thereto. Also provided is a switching member for switching among a first mode for transmitting the driving force to the developing rollers of all of the process cartridges, a second mode for not transmitting the driving force to any one of the developing rollers, and a third mode for transmitting the driving force only to the developing roller of a black process cartridge.
