In the editing mode where data is read out from a disk for a desired editing process and the thus-edited data is recorded back onto the disk, the data readout from and recording onto the disk are performed alternately. At storage locations of a memory previously occupied by data read out and supplied for reproduction, there are sequentially stored compressed data to be recorded that have been obtained from editing the read-out data. Data readout from the disk is performed until the data stored unread in the memory reaches a predetermined amount. When the data amount in the memory has reached the predetermined amount, the data are read out from the memory and recorded onto the disk by a predetermined unit amount.

In a process cartridge detachable from an image forming apparatus, presssure contact between a charging member, and an image bearing member for bearing an image can be released. Hence, it is possible to prevent the occurrence of traces caused by pressure, creep, and contamination in the image bearing member and the charging member. In addition, by arranging so that the process cartridge cannot be mounted in the image forming apparatus in a state in which the pressure contact between the charging member and the image bearing member is released, failure in charging on the image bearing member by the charging member can be prevented.

When the power source voltage is charged to a capacitor between the source side of a MOSFET and a saturation reactor at the time of starting, the gate voltage of the MOSFET is caused to rise. When this charging voltage or the gate voltage exceeds the threshold voltage, the MOSFET is energized. The energization of this MOSFET induces a voltage in the tertiary self-excited oscillation winding through the primary winding, and a part of the induced voltage is applied to the gate of the MOSFET while some other part is applied to the reactor. This causes the magnetic flux of the saturation reactor to be set to the direction opposite that which had been set before. When the product of the voltages applied to the saturation reactor has reached the level for the allowable saturation magnetic flux density the saturation reactor is saturated and the gate voltage is discharged to turn off the MOSFET. When the MOSFET is energized once, the setting and resetting of the saturation reactor is repeated alternately due to the actions of the primary winding and the tertiary self-excited winding to enter the state of stable operation.

Disclosed is a full-wave output type forward converter wherein a main transformer having a primary winding connected in series with a switching element includes two secondary windings as winding halves divided by a center tap and electromagnetically coupled. A leakage self inductance can be reduced to obtain a high-frequency, high-power arrangement.

[Problem] An object of the present invention is to provide a novel anticancer drug which is useful for treating prostate cancer accompanying androgen receptor mutation[Means for Solution] The present inventors conducted thorough research on mutant androgen-related diseases for which the traditional anti-androgen drugs become ineffective. As a result, they found that the compound, which is an active ingredient of the pharmaceutical composition of the present invention, exhibits an inhibitory action against transcriptional activation in a human mutant androgen receptor (AR), and has an excellent antitumor action in a human prostate cancer-bearing mouse, thereby completing the present invention. Accordingly, the compound, which is an active ingredient of the pharmaceutical composition of the present invention, is useful for a series of androgen receptor-related diseases including prostate cancer.
