Title: Connecting hardware for joint
Inventor: NAKANO EIKICHI
IPC: E04B1/58
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To provide a simple and sturdy lengthwise connection by applying the constitution that a metallic plate having an inverted trapezoidal form with a tubular part wound around both side pieces is fitted into a slantwise hole formed on a wooden material end. SOLUTION: Tubular parts 4 and 4' are wound around both lateral sides of a metallic plate 3 having an inverted trapezoidal form, thereby forming jointing hardware. Thereafter, notches 6 and 6' slantwise holes 7 and 7' and a through-hole 8 are formed on the ends of square timbers A and B. At the time of connecting the square timbers A and B to each other, the plate 3 and the tubular part 4 are driven into the notch 6 and the slantwise hole 7 of the square timber A. Then, a fixing pin or the like is inserted in the through-hole 8 and passed through a corresponding fixing hole 5, thereby fixing timbers A and B to each other. Also, the notch 6' and the slantwise hole 7' on the lower surface of the square timer B are aligned with the upper side 1 of the plate 3 projected from the joint edge of the square timber A, and the upper surface of the tubular part 4'.  Then, the upper surface of the square timber B is hammered and the square timber B is pulled toward the square timer A via the wedge action of the tubular part 4'. The square timbers A and B are thereby jointed to each other in a pressed contact state and fixed with a fixing pin. According to this construction, a jointing work can be easily and quickly executed, and the hardware is not conspicuous, thereby preventing a lowering in good appearance.

Title: Rotary compressor
Inventor: FUJITA SHIGERU
IPC: F04C29/12
Filed: 1994-06-01
Abstract: PURPOSE:To improve compression efficiency by forcing the cross-sectional form of a suction hole, provided at the cylinder of a compression device provided in a closed casing, into elliptic shape with two circles connected by tangential lines. CONSTITUTION:A suction hole 100 provided at the cylinder 7 of a compression device is formed into elliptic cross-sectional form with two circles 101 of the same diameter connected by tangential lines 102, 103, and positioned in such a way as to be extended in the axial direction of the cylinder 7. This suction hole 100 can narrow the rotating direction width of the cylinder internal wall by making the sectional-area height high, and also can make a compression stroke angle theta2 larger than a conventional compression stroke angle while being set to the same sectional area as a suction hole bored in a conventional cylinder. Displacement capacity can be thereby increased even with the same compression chamber height, diameter and eccentric quantity as the conventional one, and the adoption of HFC 134a as compression refrigerant enables an approach to refrigerating 1 capacity equal to that of an existing compressor adopting R12 1 refrigerant.

Patent JP-H09306674-A (JP)
Title: Lighting system
Inventor: ITO FUMIAKI
IPC: H05B37/02
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To make approximately constant the illuminance of an illuminated surface irrespective of the reflectance of the illumination area by correcting a dimming control signal in accordance with the output signal from a reflectance sensing part. SOLUTION: When the output signal from an illumination sensor 8 becomes equal to the reference data, the illuminance of the illuminated surface is measured by a reflectance sensor 9, and the emitted result is compared by a judging part 10 with the set illuminance set by an illuminance setting part 7. If the two are different, the output signal from the illuminance sensor 8 is corrected by a signal correction part 11, sent to a comparison part 5, and fed to a lighting circuit 2 so that the photo-output of a light source 3 is regulated. If the two values are equal, the output signal from the illuminance sensor 8 is not corrected by the correction part 11, but sent directly to the comparison part 5. The part 5 compares the output signal from the correction part 11 with the reference data, and the light source 3 is left in dimmer control until the two become equal.  Thus the influence of the reflectance of the illumination area upon the dimming control can be suppressed easily.

Therefore, even if a high voltage is applied across the winding 14 at the time of conducting withstand voltage tests, the electric field from the winding 14 is evenly distributed toward the embedded members 15 in the molded resin 18.

IPC: B01D53/62
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To treat dust being a solid in exhaust gas or carbon monoxide or carbon dioxide being a gaseous component therein. SOLUTION: Aluminum A is introduced into a reaction container 1 and heated by an electric heater 8 to be melted. Next, exhaust gas is blown into the container 1 in a fine bubble form from a plurality of blowoff ports 3. Since the substance reduced in molten aluminum A and aluminum oxidized therein are gathered to the upper surface and bottom of molten aluminum A by the specific gravity difference from molten aluminum A, they are appropriately taken out of lower and upper taking-out ports 4, 5 to be recycled. The reduced substance and aluminum vapor contained in the exhaust gas passed through molten aluminum A are cooled by a cooler 11 to be removed. The exhaust gas from which dust is removed is discharged to the atmosphere from an upper gas exhaust pipe 10.
