Abstract: PURPOSE:To facilitate adjustment through simple constitution, and to reduce the cost by providing a cylindrical lens closely to a photosensitive drum, and adjusting the position of an imaging lens with the screw of a lens barrel in combination with a general spherical lens. CONSTITUTION:A cylindrical lens 15 is arranged right in front of a photosensitive drum 14, and a focusing convergent lens 12 is stored in the same lens barrel in combination with a general spherical lens to adjust its position with a screw at the external circumference. The cylindrical lens 15 correct the inclination of reflective surfaces of a rotary polygon mirror 13, allows a laser beam to reach a certain line on the recording surface of the drum 14, and also converts the shape 16 of the spot into a shape 17. On the other hand, when the screw of the lens 12 is turned, the relative interval between the lens 12 and a semi-conductor laser 1 is adjusted to image a spot at a prescribed position of the drum 14. Thus, the constitution and adjustment are simplified and the cost is reduced.

Title: Vehicle speed controller for working vehicle
Inventor: MINAMI TERUO
IPC: A01D69/00
Filed: 1990-05-09
Abstract: PURPOSE:To carry out the proper deceleration by operating an actuator with a previously set operation quantity when the detected car speed is the speed for the operation of an elastic versatility part, while obtaining the operation quantity from the difference between the detected car speed and the target car speed when the detected car speed is not sufficient for the operation of the elastic versatility part. CONSTITUTION:It can be judged from the value of the detected car speed if a speed change device 3 reaches the limit on the high speed side of the speed change range or not. Accordingly, it can be judged from the detected car speed if the speed change range reaches the limit on the high speed range, and an elastic versatility part 11 is in operation or not. Accordingly, when the elastic versatility part 11 is in operation, a speed change actuator 8 is operated with the previously set operation quantity, and the actual deceleration quantity is not proportional to the operation quantity, and deceleration is carried out surely, and the load can be lightened. When the detected car speed is the speed which does not operate the elastic versatility part 11, the operation quantity of the actuator 8 is obtained according to the difference between the detected car speed and the target car speed for deceleration, similarly as conventional.

Title: Ink jet recorder
Inventor: SUGIYAMA KATSUYASU
IPC: B41J2/18
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent color mixing of image on a recording sheet surely without requiring useless ink ejection and to finish ink suction therefor in a short time. SOLUTION: In the ink jet recorder, the majority of ink being sucked from each ink ejection opening C1-Cn, M1-Mn, Y1-Yn flows from one of two ink discharge openings 102, 103 closer to the ink ejection opening C1-Cn, M1-Mn, Y1-Yn and about one half of total quantity of discharged ink is distributed to each ink discharge opening. Since the ink stands lower when in suction as compared with a conventional recorder, ink of different color is prevented from adhering to the ink ejection opening C1-Cn, M1-Mn, Y1-Yn and color mixing during recording can be prevented.

Title: Image forming device
Inventor: TAKAHASHI TSUNESHI
IPC: G03G21/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To maintain an initial image state of a product. SOLUTION: In this device, specified fixing test images TA to TC are formed on a recording medium S in the initial state (S1, S2). Then, initial glossiness of each of the fixing test images TA to TC are separately calculated and stored by a central control part based on the strength of reflected light, etc., obtained at an image information detection part (S3). Then, the fixing test images TA to TC are formed again periodically at a specified timing (S5 to S7). Next, the glossiness of each of the fixing test images TA to TC are calculated, compared with the initial glossiness and electrifying voltage value of a 1st to 3rd electrifying chargers are compensated based on the detected result (S8 to S14). Thus, if a condition for fixing is constant, since the toner attachment quantity is varied, the glossiness is also varied to be equivalent to the initial glossiness.  Therefore, the state of image at the initial state is maintained.
