Title: High-hardness electroless nickel-boron plating liquid and plating method using this liquid
Inventor: MURAI TOSHIAKI
IPC: C23C18/34
Filed: 1992-05-28
Abstract: PURPOSE:To obtain a high-hardness plating film without subjecting the film to a high-temp. treatment by allowing borate ions and ammonium ions to exist into an electroless nickel-boron plating liquid. CONSTITUTION:This electroless Ni-B plating liquid is prepd. by incorporating nickel ions, boric acid-based reducing agent, borate ions and ammonium ions into the liquid. The high-hardness film is obtd. by using this plating liquid without subjecting the film to the high-temp. treatment and, therefore, the deformation of a blank material having low heat resistance is prevented. Plating is executable with precise dimensional accuracy even with the blank material with which the deformation, etc., do not arise. In addition, the film is made smooth and is improved in the appearance by adding amines, such as alkanol amine, to the above-mentioned plating liquid.

IPC: B60L3/00
Filed: 1990-05-29
Abstract: PURPOSE:To broadcast arrival at appropriate time coping with open timing of the door of a train by performing a necessary arrival broadcast when an on-track signal indicating a train on the track of a platform and an open signal indicating the open door of a train are input. CONSTITUTION:When a train 1 is entered into the track circuit 3 of a previously decided platform 2, it is detected with an on-track detecting pat 4 and an on- track signal is output to a broadcasting control part 15.

Title: Printing head for thermal printer
Inventor: KADOUCHI ATSUSHI
IPC: B41J2/345
Filed: 1987-05-30
Abstract: PURPOSE:To contrive higher printing quality, by inclining insulators provided between heat generating elements relative to a printing direction, in a thermal head comprising a plurality of heat generating elements arranged in a line orthogonal to the printing direction. CONSTITUTION:A printing head comprises a plurality of heat generating elements 11 arranged in a line in a paper-feeding direction Y, with insulators 12 between the heat generating elements 11 being inclined relative to a printing direction X, resulting in that the heat generating elements 11 are also inclined relative to the printing direction X. As for the distribution of the quantity of heat being supplied to each point on a straight line l in the paper-feeding direction when the heat generating elements 11 are passed through a position A on a recording paper while generating heat, there is a small heat quantity difference between a part Pa through which the center of the insulator 12 is passed and a part Pb through which the center of the heat generating element 11 is passed, because the insulators 12 are inclined relative to the printing direction. Therefore, even when the width of the heat generating element can not be reduced to a large extent reduced, a gap between dots or a part with a lower printed density will not be generated, and printing quality can be thereby enhanced.

Title: Bearing device for vertical shaft type rotary machine
Inventor: KITORA YOSHIHISA
IPC: F16N7/36
Filed: 1983-07-25
Abstract: PURPOSE:To suppress splashing of oil, by providing a baffle plate having an opening through which oil passes in such a manner that the baffle plate is located below an oil level in operation, and mounting a baffle cylinder to the baffle plate in such a manner that the baffle cylinder is upwardly projected from the oil level in operation. CONSTITUTION:When an outer cylinder 2 is rotated, oil in an area (a) interposed between a baffle cylinder 11 and the outer cylinder 2 is rotated to form a parabolic oil surface. An oil level on an inner circumferential surface of the outer cylinder 2 is substantially proportional to a difference in radius of the outer cylinder 2 and an inside cylindrical member 3c, and a critical rotational speed at which a flow starts being unstable is substantially reversely proportional to the abovementioned difference in radius. Accordingly, the provision of the baffle cylinder 11 reduces the difference in radius to suppress an elevation of the oil level and stabilize the oil level with a laminar flow maintained. Further, although a vertical vibration is applied to the oil in the area (a), such a vertical vibration of the oil level may be suppressed by an orifice damper effect of a baffle plate 9 and an opening 10 mounted to the plate 9.

Abstract: PURPOSE:To prevent surely hard soil and soft soil from occurring, by keeping the temp. of the cooling water fed in cooling water paths formed on the side wall of a vacuum chamber, in a specific temp. range being lower than the temp. in the vacuum chamber. CONSTITUTION:A number of cooling water paths 5 are formed on the side wall of a vacuum chamber 2 and cooling water is fed from a tube path 9 to the cooling water path 5 through a pump 7, a check valve 8 and so on from a heat exchanging tank 6 and is returned again in the heat exchanging tank 6 from a tube path 10 of the return side. Temp. of the cooling water and temp. in the vacuum chamber 2 detected by means of a cooling water temp. sensor 16 and a temp. sensor 17 are input in a temp. difference meter built in a controller 14, which controls the flow volume of the cooling liquid and the output of a heater 12 in such a manner that the temp. of the cooling water is always 2-6 deg.C lower than the temp. in the vacuum chamber 2. It is thereby prevented that the soil adhered on the side wall of the vacuum chamber 2 becomes hard soil and that dew is produced by cooling excessively the side wall of the vacuum chamber 2.

Title: Three phase transformer with stabilizing winding
Inventor: ONO MASARU
IPC: H01F30/12
Filed: 1979-10-24
Abstract: PURPOSE:To reduce the length of connecting leads and to facilitate the assembling by performing the reverse winding only in a phase II, and providing the insulation reinforcing part only on the phase II without extending the insulation distance. CONSTITUTION:Only the phase II of the core-type three-pase transformer is reversely wound, and the position of a terminal T3 and that of T1 are exchanged. The connecting leads of a bottom terminal T3 of the phase II is connected to a bottom terminal T3 of a phase III. An upper terminal T1 of a phase I and an upper terminal T1 of the phase III are connected and grounded. The insulation reinforcing part 9 is attached to only the top of the stabilizing winding of the phase II. In this constitution, since the upper terminal T1 of the phase II is connected to the grounding lead 5 and the large voltage is not generated in the phase II, the insulation reinforcing part is not required. Therefore, the phases I and III are not changed, and the insulation reinforcing part 9 is attached only to the phase II. In this method, the length of the lead can be remarkably reduced, the assemblying work is easy, and the inexpensive transformer can be obtained.

IPC: D05B47/06
Filed: 1993-06-10
Abstract: PURPOSE:To provide a thread tension detector for a sewing machine, capable of stably detecting the tension of the thread regardless of temperature variation. CONSTITUTION:A composite piezoelectric device 22 is formed by putting together two piezoelectric elements 20 and 21 having polarizing characteristics reverse to each other respectively When an upward force is applied to the composite piezoelectric device 22, a compressive force acts on a section of the piezoelectric element 20 between a yarn guide 23 and a holder 24, and a tensile force acts on a section of the piezoelectric element 21 between the yarn guide 23 and the holder 24. Since the polarizing characteristics of the piezoelectric elements 20 and 21 are reverse to each other, the quantity of charges on the electrodes 25 and 26 of the composite piezoelectric device 22 are twice the quantity of charge produced by the piezoelectric element 20 or 21. Thus, charges proportional to temperature cancel each other, and the charge produced by force corresponding to the tension of the thread is enhanced.
