A copy machine having a plane stationary platen for holding an original and having also capability in facsimile transmitter and receiver is disclosed. A first scanning mirror is driven in parallel with the platen surface at the same speed as a photosensitive medium. A second scanning mirror is driven synchronously at half the speed of the first scanning mirror and in the same direction. An in-mirror lens comprises a reflex mirror and a spherical lens system and a fourth fixed reflex mirror is lo...

A device for correcting the time displayed on an electronic timepiece having a standard oscillator, a frequency divider bank, a time display unit, a reversible driver and an external actuating member for correcting the time display from the exterior of the timepiece. In the device, means, including an on-off switch, for applying a correcting signal at a variable frequency is connected to the driver through a normal-reverse switch, and these means are arranged for interlocking operation with the ...

A color image reproduction apparatus capable of producing a polychromatic reproduction of a color original is disclosed. The apparatus includes a light scanner for scanning the color original to be reproduced to thereby form a light image. A prism or a plurality of color filters are arranged for color-separating the light image into red, green and blue light images and a memory is provided for memorizing those color-separated light images. A plurality of marking units are arranged around a trans...

Novel 16.beta.-hydrocarbon substituted estrane compounds are provided represented by the formula: Wherein A is hydrogen or an acyl radical and R is a hydrocarbon radical having at least 2 carbon atoms. These novel compounds are characterized by a highly effective anti-androgenic activity.

Novel steroid compounds are provided represented by the formula: ##SPC1## Wherein each of R.sup.1 and R.sup.2 represents hydrogen or methyl group or R.sup.1 and R.sup.2 may be combined with each other to represent methylene group, n is 2 or 3 and the dotted line means a double bond at 6-exo-position when n is 2 or between 6- and 7-position when n is 3. These novel compounds show a strong anti-androgenic activity, especially by oral administration, and can be used as a remedy for the prostatomega...
