Title: Formation of zinc film onto aluminum material
Inventor: IWAMA TETSUJI
IPC: C23C18/52
Filed: 1984-07-23
Abstract: PURPOSE:To form a thick Zn film having excellent adhesiveness by forming preliminarily the Zn film then activating the same and forming again the Zn film in the stage of forming the Zn film for corrosion prevention on the surface of an Al material for the tubes, fins, etc. of a heat exchanger. CONSTITUTION:ZnO is dissolved into an aq. NaOH soln. and the tubes and fins of the heat exchanger made of Al or Al alloy are dipped for 30-60sec into a basic Zn bath having 30-110g/l ZnO concn. and 300-500g/l NaOH concn. and kept at 20-50 deg.C to form the dense Zn film having the excellent adhesiveness on the surface of the Al material to 1-2g/m<2> thickness. The tubes or fins are then dipped for 10-30sec into an aq. NaOH soln. having 0.1-48wt% NaOH concn. and kept at 45-55 deg.C to activate the Zn plating surface. The tubes or fins are again dipped into the Zn-contg. NaOH liquid similar to the above-mentioned soln. by which the thick Zn film for corrosion prevention having the excellent adhesiveness is formed in a short period.

Title: Control circuit for laser frequency
Inventor: SUKEGAWA OSAMU
IPC: H01S3/139
Filed: 1983-08-19
Abstract: PURPOSE:To improve the accuracy of a control system and increase the speed of its operation by providing a fine displacement system in a laser mirror with a system having large positional displacement capability in a narrow zone and a system having small positional displacement capability in a wide zone. CONSTITUTION:A driving block is constituted by an amplifier 21 having a wide amplitude dynamic range in a narrow zone and an amplifier 22 having a low amplitude dynamic range in a wide zone, a false signal 23 is separated and amplified, ana a piezo-element 24 is driven. A low-frequency change due to a thermal factor is controlled through the amplifier 21 having the wide amplitude dynamic range, and noises can be lowered because the amplifier 21 may be used in the narrow zone. A high-frequency component by a vibration is controlled through the amplifier 22, which is operated at high speed and has the low amplitude dynamic range. Since the quantity of variation of the high-frequency component is smaller than that of a low-frequency component, an amplification degree and the amplitude dynamic range are sufficient even when they are smaller than those of the amplifier 21, thus allowing the increase of the speed of operation and the reduction of noises.

Title: Adaptive clamp circuit for ghost eliminating device
Inventor: KITAMURA KAZUHIRO
IPC: H04N5/16
Filed: 1990-06-08
Abstract: PURPOSE:To obtain a clamp circuit able to correctly recover a DC component of a video signal by providing a means discriminating whether the synchronization is stable or unstable and a means selecting a video signal subject to pedestal clamp with a vertical keyed pedestal clamp circuit when the stable synchronization is discriminated. CONSTITUTION:A video signal Sin given to an input terminal 1 is divided into two systems via a buffer 14 and an amplifier 17, the one is led to a SYNC tip clamp circuit 11 via a buffer 15 and the other is led to a V keyed pedestal clamp circuit 12 via a buffer 16. When a horizontal synchronizing signal and a vertical synchronizing signal included in a received television signal and a basic clock in a ghost eliminating device are in a prescribed relation the synchronization is discriminated to be stable. Based on the result of discrimination, the video signal pedestal-clamped by the V keyed pedestal clamp circuit 12 is selected and the result is outputted as a video signal after clamping. Thus, the DC component of the video signal is correctly recovered regardless of occurrence of a ghost fault.

Title: Buoyancy pump including lifting mechanism
Inventor: SHIMOJIYOU KENICHI
IPC: F03B17/00
Filed: 1980-10-30
Abstract: PURPOSE: To increase the water lifting height, by connecting a pipe having a small diameter to an upper portion of a float so that water above the float can be lifted to a higher level with lifting of the float.  
     CONSTITUTION: When a water inlet valve 6 is opened, a float 9 is raised while draing water in a water supply tank 3. At the same time, a gate valve 1 is moved upward, so that water above the float 9 is lifted into a water reserving tank 11 via a water lifting pipe 10. When the float 9 is stopped at least an upper portion in a water chamber 12, both of the gate valve 1 and inlet valve 6 are closed. Subsequently, when water in the chamber 12 is discharged into a discharge tank 8 by opening a discharge valve 7, float 9 falls to the bottom of chamber 12. Then, the discharge valve 7 is closed and inlet valve 6 is opened.  While the float 9 is being raised, vane wheels 5 are turned for preventing water  above the float from flowing downward. In the above arrangement, if the discharge tank 8 is divided vertically in a plurality of sections and the discharge  valve 7 is provided in each section, energy required for lifting water can be  saved by opening the discharge valves 7 from a higher one successively.
