Abstract: PURPOSE:To form an Image pattern with, for example, ground pattern. etc., on the background of an original image transferred on a transfer-sheet with inexpensive and simple constitution. CONSTITUTION:Toner density attached on a photosensitive material 6 is varied based on the light quantity of an exposure lamp 3, electrification quantity on the photosensitive material 6 by an electrifier 7, and the developing bias of a developing roller 9.

Title: Injection apparatus of injection molding machine
Inventor: ENDO TAKANORI
IPC: B29C45/60
Filed: 1987-03-30
Abstract: PURPOSE:To make it possible to obtain stably a molded item having a good pattern such as a marble pattern and so on, by setting a hopper for a main raw material on the downstream side of a hopper for a auxiliary raw material, transferring the auxiliary raw material through the first screw channel, transferring the main raw material through the second screw channel and moreover setting a hole part for drop ping the main raw material eccentric from the center of a screw axis. CONSTITUTION:When a shutter 8 of a hopper B for a auxiliary raw material is opened and a shutter 10 of a hopper A for a main raw material is closed, rotation of a screw 5 is started. The auxiliary raw material enters into the first screw channel 6 and is transferred forward. When the auxiliary raw material reaches the downstream side of a shute 11 in a specified time, the shutter 10 is opened. At this time, the main raw material hardly enters into the first screw channel 6 due to the auxiliary raw material entering therein and naturally enters into the second screw channel 7 and is transferred forward. Moreover, the shute 11 is set eccentric from the center of a screw 5 axis. This process effectively prevents the auxiliary raw material from moving to the second screw channel 7 due to the swelling when it reaches below the shute 11 and it is possible to obtain a pattern.

Abstract: PURPOSE:To make the light amount of an exposure lamp obtain enough image reproducing ability when a chromatic color image is reproduced by using a color filter cutting the color component of yellow. CONSTITUTION:Two filters of the color filter Fc and a black filter Fbk are prepared as filter 38 and a specified filter out of them can be preceded into and receded from a light path. The color filter Fc is used when a chromatic color original is chromatically reproduced. For instance, when a hologram lamp is used as the exposure lamp 29 and when a photosensitive body having sensitivity to red color light is used the yellow component of an original is absorbed about 95% and a red component, about 30%. That is, when the color filter Fc is inserted into the light path, the reflection light amount of the chromatic color image irradiated by light is reduced to the same degree as the reflection light of light projected on a black color image. Thus, the light amount of the exposure lamp 29 can obtain enough image reproducing ability.
