Title: Developing device
Inventor: TAKAMI NOBUO
IPC: G03G15/09
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent developer from sticking on a developer carrier and a photoreceptor due to excess developer at ends of the developer carrier, by providing second developer-restricting members, which restrict a developer layer thickness, onto both the ends that are upstream from a developer restricting member in a developer carrying direction. SOLUTION: Pre-doctors 7 are provided upstream from a doctor 6 in a developer carrying direction, that is, upstream in the direction of the rotation of a developing roller 1, and they are provided opposite both ends of the doctor 6 and with a developing area between them. Namely, the pre-doctors 7 are provided upstream from the doctor 6 in the direction of the rotation of a developing sleeve and opposite both the ends of the doctor 6. Accordingly, amounts of developer held on both the ends of the developing sleeve are double restricted by the pre-doctors 7 and doctor 6, carrying of excess developer is eliminated, and the developer is prevented from caking on the developing sleeve and a photoreceptor drum.  That is to say, a magnetic field is generated between the pre-doctors 7 and the developing sleeve, the developer is catenated between them, an amount of the passage of it is restricted.

Title: Air current floated type air plane model device
Inventor: HAN MASATERU
IPC: A63H27/133
Filed: 1988-02-09
Abstract: PURPOSE:To control an air current blowing angle on a control board so that an airplane model can be launched and landed, by disposing rails extending from the blow duct side to a launching and landing bed section and provided on the end with an engaging means removably attached thereto be connected to the airplane model. CONSTITUTION:Two rails 14 have on the ends an engaging line 15 orthogonally intersecting said rails. An airplane model 1 is connected to said rails by hooking on said line 15 removably a pair of left and right hooks 16, 16 provided on wings 2. A handle 9 is provided to change the direction of a duct vertically and adjust a blast angle. When a blast control machine 8 is operated and dynamic lift is generated on the wings 2 by air current blown from a duct 5, an airframe is gradually floated. When the direction of blast is shifted upward by the control of handle 9, the airplane model is completely kept away from a launching-landing bed 12 to take a flying pose. When the blast direction of air current is directed upward, the airplane model 1 increases its altitude and keeps similar flying pose even when the blast control machine 8 is pivoted left and right in a duct fixing section 11 or removed from a control bed 10. Also, when the airframe is lowered from the flying condition by the operation of handle, the landing operation is carried out.

Filed: 1995-02-17
Abstract: PURPOSE: To improve the electromigration resistance and stress migration resistance of Al wiring. CONSTITUTION: An Al film is grown after the sectional profile of a groove at the surface of a water W within a DC magnetron sputtering unit 100, and then this water W is carried in high vacuum to a heating unit 101, and is placed on a heating stage 12. While giving ultraoscillation to the water W with a quartz oscillator 16 built in the heating stage 12, the water W is heated in the temperature range of about 350-600 deg.C lower than the fusing point of a bulk solid Al so as to perform low-temperature reflow. The groove is stopped with an monocrystallized Al film. Accordingly, because minute oscillation is used jointly at the time reflow, equal stopping becomes possible regardless of the size or density of the groove, and a highly reliable single crystal wiring can be formed in a self alignment manner.
