Inventor: WATANABE YOICHIRO
IPC: G03G15/05
Filed: 1986-02-25
Abstract: PURPOSE:To optically memorize an original image on the surface of a photosensitive body within a short time by electrostatically charging the memory photosensitive body in which the original image is memorized to form an electrostatic latent image, developing the latent image with toner, uniformly exposing the photosensitive body, and then transferring the toner image to recording paper. CONSTITUTION:A uniform exposure means 15 is arranged between a developing means 4 and a transfer means 6 independently of a memory exposing means 5. The memory photosensitive body 10 is uniformly charged by a charging means 2 and an original image is exposed by an exposing means 3 to form an electrostatic latent image. Then, the electrostatic latent image is developed with toner by a developing means 4 and then ligth is projected to the photosensitive body 10 by the memory exposing means 5, so that the electrostatic latent image on the photosensitive body 10 is optically memorized. The toner image on the photosensitive body 10 is transferred to the carried recording paper by a transfer means 6 and the recording paper is separated from the photosensitive body 10 by a separating means 7 and carried to a fixing means to fix the toner image on the recording paper. Consequently, the original image can be memorized on the photosensitive body within a short time.

Filed: 1992-01-31
Abstract: PURPOSE:To prevent occurrence of deterioration in a leap-up shape in the leakage characteristic around a voice carrier by providing an impedance matching device to an absorbing resistance terminal of a 3dB coupler. CONSTITUTION:A stub tuner 5 is connected to a terminal of an absorption resistor 4. Thus, a signal appearing at the terminal of the resistor 4 is reflected partly by the stub tuner 5.

Through the constitution above, the stub tuner 5 is made variable to change a level of a reflection signal, and when the reflection signal reaches a same level as that of a leakage signal in opposite phase, the leakage signal is cancelled and minimized. Thus, the deterioration in the leakage characteristic is easily adjusted.

Abstract: PROBLEM TO BE SOLVED: To obtain a single crystal at a good yield without widening the part of the straight cylindrical part of the single crystal having dislocation by pulling up the straight cylindrical part, then increasing the heating output of a heater to form a tail part at the time of growing the single crystal by a CZ method. SOLUTION: A crucible 1 is arranged in a chamber 7 and the raw material in the crucible 1 is heated by the heater 2 and is melted to form a molten liquid 3. The seed crystal 5 disposed at the bottom end of a wire 4 is then brought into contact with the surface of the molten liquid 3 and is pulled up to grow the single crystal 6. After the straight cylindrical part 6c of the single crystal is pulled up, the heating output of the heater 2 is increased to form the tail part 6d of the single crystal 6. As a result, the heating output of the heater 2 is increased to increase the temp. of the surface of the molten liquid 3 even in the case the pulling up speed of the single crystal 6 is kept constant, by which the speed for growing the single crystal 6 is lowered and the diameter of the straight cylindrical part 6c is gradually reduced. The adequate tail part 6d is thus formed.
