Title: Image forming device
Inventor: MIYAKE HIROYUKI
IPC: G03G15/043
Filed: 1983-06-13
Abstract: PURPOSE:To form the forward blank part of an image sharply by providing an LED array other than an image exposing optical system near an image exposing area, and turning on the LED array so as to illuminate the forward area of an image just at an accurate timing of image exposure. CONSTITUTION:When an image head signal is produced and a drum moves by the peripheral drum distance (d) from an image exposing position A to an LED array 22 fixed position, the head of a latent image on the photosensitive drum 1' corresponding to an original comes to said position of the array 22. Therefore, a number of clock pulses t1 corresponding to the distance (d) is counted from the production of the image signal with a drum motor clock or the like, and after the lapse of predetermined clock number t2 corresponding to the forward blank part, the array 22 is turned off. When an optical system begins to return, the array is turned on to erase electrostatic charge on the drum 1', and attachment of a developer to the drum 1' is prevented during nonoriginal scanning, and the array 22 is turned off after the forward blank has been formed at the next copying, thus permitting formation of the forward blank sharply.

Title: Counter
Inventor: SERA KATSUMI
IPC: H03K21/02
Filed: 1982-06-21
Abstract: PURPOSE:To attain measurement with good accuracy even for a short measuring period, by changing the polarity of a clock inputted to a counter depending on the polarity of a reference clock at the start of count. CONSTITUTION:A count starting signal is inputted to a terminal 7 to reset T FFs 14, 15 constituting the counter, and inputted to a T input of a D FF9 to latch the state of a reference clock input terminal 8 in this state. As a result, either of NAND gates 11, 12 is activated. For example, when the state of the terminal 8 is ''H'', the NAND gate 11 is activated. Thus, the reference clock is inverted finally via an inverter 10, the NAND gate 11 and an NAND gate 13 from the input terminal 8 and inputted to the counter. Inversely, when the input terminal 8 is ''L'' at the start of count, the clock is inputted finally to the counter with the original polarity via the NAND gates 12 and 13. Thus, the error of measuring period is suppressed within a half period of the reference clock.

Abstract: PROBLEM TO BE SOLVED: To obtain a light amplifier whose gain is enhanced in stability in a wide range of temperature without controlling it with a complicated electronic circuit, by a method wherein exciting light emitted from an exciting light source is made to impinge on an optical fiber through the intermediary of a temperature compensator. SOLUTION: A temperature compensator 11 is disposed between an optical multiplexing/branching device 2 and an exciting light source 3. Exciting light emitted from the exciting light source 3 is made to excite a doped fiber 1 through the intermediary of the temperature compensator 11 and the optical multiplexing/branching device 2 shown by a broken line. On the other hand, signal light inputted through an input terminal 9 shown by a solid line is inputted into the doped fiber 1 through a first optical isolator 4, amplified by the doped fiber 1 optically excited, and taken out through an output terminal 10 through the intermediary of the optical multiplexing/branching device 2.  When an ambient temperature varies, the temperature compensator 11 is so changed in insertion loss as to cancel a gain change in the doped fiber 1 to keep an optical amplifier of this constitution constant in gain.

IPC: C04B35/04
Filed: 1990-04-20
Abstract: PURPOSE:To improve spalling resistance by adding alumina-zirconia type starting material to magnesia-based starting material for refractories in a prescribed ratio. CONSTITUTION:Alumina-zirconia type starting material is added to magnesia- based starting material for refractories by 1-10 pts. wt. per 100 pts. wt. of the magnesia-based starting material and they are fired to form a magnesia-based fired firebrick.
