Title: Continuous plating device
Inventor: KAWAGUCHI HIROYOSHI
IPC: C25D7/06
Filed: 1992-11-30
Abstract: PURPOSE:To prevent the flow of a plating liquid to the contact parts of conductor rolls and a metallic strip and to prevent the overcoating of both end edges of this metallic strip with plating. CONSTITUTION:The metallic strip 1 with its transverse direction positioned perpendicularly is passed in a horizontal direction and is subjected to plating by running the plating liquid between the metallic strip 1 and anode 3a from above. The plating liquid passed between the metallic strip 1 and the anode 3a is flown out of the end in the transverse direction of the metallic strip 1, by which the remaining of the plating liquid on the front surface of the passing metallic strip 1 is prevented and an effect of liquid draining is enhanced. A jet header 4 for supplying the plating liquid is lifted according to the width of the metallic strip 1 to prevent the concentration of current to both end edges of the metallic strip 1.

Title: Laser
Inventor: ASAMURA FUMIO
IPC: H01S3/086
Filed: 1990-11-30
Abstract: PURPOSE:To perform temperature compensation of thermal expansion strain of a rod frame for holding a resonance mirror by so outputting a control signal as to compensator the strain of the frame based on the detected temperature of a temperature sensor connected to a controller, and driving a piezoelectric actuator. CONSTITUTION:Temperature sensors Ta1-Ta3, Tb1-Tb3, Tc1-Tc3 are set at substantially the same positions on rod frames 3a-3c, and piezoelectric actuators 4a, 4b are respectively set to one ends of control rod frames 3b, 3c. Elongated strains of thermal expansion occur at the frames 3b, 3c with respect to a reference rod frame 3a, since the strain is an amount depending only upon the temperature, if the actuators 3b, 3c are so controlled to be driven reversely in a direction for contracting them based on detected temperature difference therebetween, a temperature is compensated so that the strain becomes zero. Thus, an unparallel strain between resonance mirrors can be compensated.

Abstract: PURPOSE:To prevent a slip on a snow road or the like by switching an auxiliary transmission to the high side when a main transmission is set to the reverse side and the winter mode is set, and switching it to the low side when the winter mode is not selected. CONSTITUTION:An electronic control device (e) for a main transmission forming multiple forward shift stages and one reverse shift stage with solenoid valves S1, S2 and an auxiliary transmission allowing high/low switching with a shift solenoid S3 allows a start at stages other than the lowest stage of the main transmission when a vehicle is started in the winter mode detected by a detecting switch (d). If a switch (c) detects that the main transmission is set to the reverse side when the winter mode is selected, the auxiliary transmission is switched to the high side. When the winter mode is not selected, the auxiliary transmission is switched to the low side. The high reverse gear is operated when a vehicle is reversed on a low-mu road such as a snow road or a frozen road, and reverse running can be surely performed with no slip.

The circuit 40 receives two signals having the same amplitude and the same phase, adds these two signals by a combiner 68 consisting of a resistor circuit network and obtains a differential output signal proportional to a difference between the 1st and 2nd electric signals. When the photodiodes having terminal resistors 45, 64 are adopted, the photodiodes and amplifier circuits can be mutually connected through coaxial cables. Since respective amplifier circuits can be formed as current sink or source types, amplifier circuits of high speed operation can be adopted.

Title: Coating method of metal member
Inventor: KUROKI RYOICHI
IPC: F16L58/10
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To suppress boiling of a cooling water and to maintain smoothness of a coating film in the process to cool and solidify a melted layer of a thermoplastic resin coating material formed on the surface of a metal member, by bringing a cooling water containing a specified amt. of a water-soluble low mol.wt. polyol into contact with the melted layer. SOLUTION: When a metal member such as a steel pipe for piping is coated with a thermoplastic material essentially comprising polyethylene, polyvinyl chloride, polyamide, satd. polyester, etc., by hot-melt coating, a melted layer of the thermoplastic resin coating material is formed on the surface of the metal member and then the layer is solidified by cooling to form a coating film. In this process of cooling and solidifying, a cooling water into which a water-soluble low mol.wt. polyol is compounded by 5-25% is used and is directly brought into contact with the melted layer. The cooling and solidifying rate of the melted layer can be controlled by heating the cooling water.  Thereby the wettability of the melted layer surface with the cooling water can be improved to minimize production of air bubbles during boiling, and the smoothness of the coating film can be maintained in a good state.
