Abstract: PURPOSE:To produce a cast iron alloy member having stable resistance to formic acid corrosion inexpensively by ironing the surface of a cast iron base material to form a surface coating layer consisting of an Fe-Ni solid soln. contg. an adequate concn. of Ni thereon. CONSTITUTION:The surface of the cast iron base material is coated with Ni by a method such as thermal spraying method, PVD or coating of Ni powder mixed with a binder such as PVA and thereafter high-density energy such as laser or TIG are is irradiated onto the coating from above the same to melt the above-mentioned coating layer and the surface layer of the base material under the same, thereby alloying Ni to the base material metal. the surface coating layer consisting of the Fe-Ni solid soln. is thus formed on the surface of the above-mentioned base material. The conditions thereof are adjusted in the stage of the above-mentioned alloying so that the average concn. of Ni in the surface coating layer is made 1-80wt%. The cast iron alloy member which has the resistance to formic acid corrosion and is obtd. in the above-mentioned manner prevents extremely effectively the formic acid corrosion when used for the inside surface of the cylinder bore of an engine for pure methanol, etc.

Title: Laminated type inductance element
Inventor: SATO HITOSHI
IPC: H01F27/28
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To enable easy adjustment of an inductance value by providing a plurality of inside conductor coils connected in series which do not completely share magnetic flux and have proper magnetic path. SOLUTION: An inductance L of a laminated type inductance element 1 can be expressed as L=μ0μ'.(Ae/l).N2 where μ0: vacuum permeability, μ': real part of relative permeability, Ae: magnetic path sectional area, l: magnetic path length and N: number of turns. If the number of turns of an element increases, inductance increases as a quadratic function. Therefore, with high number of turns, fine adjustment of an inductance is difficult. However, since the inductances of coils 2, 3 connected in series are expressed by the sum of each thereof, fine adjustment of inductance is possible in a region of high inductance by combining a coil of a small number of turns and a small inductance with a coil of large inductance and large number of turns. Thereby, inductance standard can be set finely.

Title: Method and device for scratching off stuck object to heat transfer plate of heat exchanger
Inventor: FURUHATA HIROYUKI
IPC: F28G1/08
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To scratch off stuck objects on the surface of a heat transfer plate efficiently by moving a chain interposed between a plurality of heat transfer plates horizontally while moving vertically between the heat transfer plates thereby sliding it between heat transfer plates facing each other. SOLUTION: A plurality of chains 3 having upper end side secured above a plurality of heat transfer plates 2 and the lower end side secured or subjected to downward tensile force are interposed across the vertical direction of the heat transfer plates 2. The chain 3 is retained sliding, at the upper and lower parts thereof, by upper and lower supports 7, 10. Since the lower supports 10 moves horizontally in synchronism with horizontal movement of the upper support 7, the chain 3 can move in the vertical direction simultaneously with horizontal movement. Consequently, the chain 3 moves vertically, horizontally and obliquely with respect to stuck objects on the heat transfer plate 2 thus scratching off the adhering matter efficiently.

Title: U-link and anchor connector connecting structure
IPC: H01R13/187
Filed: 1992-03-11
Abstract: PURPOSE:To provide a connecting structure of U-link with anchor connector which can generate fitting and separation safely and quickly. CONSTITUTION:The outer and inner members 3, 6 of an anchor connector 2 are fitted removably in/on an outer conductor 22 and inner conductor 23 of a U-link 1 without committing elastical deformation. The outer connector member 3 is in contaction with the outer conductor 22 through a contact piece 4, while the inner connector member 6 is in contact with a recess 25 formed in the inner conductor 23 with a coil spring 7 interposed. According to this arrangement, the contacting can be done with a much weaker force than conventional. Connecting and fixation and the release therefrom are generated by turning a fixing lever 10 and by detaining and separating the other end of a detent piece 11 with a lever receptacle metal piece 12. Thus fitting and removal of the U-link can be made with no use of any special tool. As a result, it can be accomplished safely and quickly, which enables high-speed response even in the event of emergency replacement.

Filed: 1979-07-12
Abstract: PURPOSE:To contrive the improvement of the edge drop, the improvement of the sheet shape, and the improvement of the roll life, by installing the upper and lower backup rolls and the axially movable upper and lower intermediate rolls, and by employing the planetary gear unit for driving the upper and lower work rolls at different circumferential speeds. CONSTITUTION:At hot rolling the steel strip S, the left end of the upper intermediate roll 3 is made to coincide with the left end of breadth of the steel strip S, and the right end of the lower intermediate roll 4 is made to coincide with the right end of breadth of the steel strip S. Next, the motors 7, 8, are driven; the lower work roll 2 is rotated by only the motor 8; since the output shaft of the motor 7 of the upper work roll 1 is connected to the planetary gear unit comprising the sun gear 9, the star gear 10, the ring gear 11, etc., and the gear 11 engaging with the gear 12 is fixed to the output shaft of the motor 8, the power of motor 7 together with the power of motor 8 are transmitted to the roll 1 which is accordingly rotated at rotational frequency different from that of the roll 2. Hereby, the rolling work is performed by rolls of different circumferential speeds; as a result, even if the load per unit length of the contact arc between rolls 1, 2, and the strip S is small, the required draft percentage can be obtained.
