Title: Turbofan and air conditioner provided with the same
Inventor: YOSHIDA SHIGERU
IPC: F24F1/00
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To prevent generation of vibration at the time of revolution of a turbofan by interposing and sticking vibration-proof rubber between the inner peripheral surface of a boss of an impeller and the outer peripheral surface of a sleeve, screwing a nut into the tip of a rotary shaft passing through the sleeve and fastening the sleeve to the rotary shaft. SOLUTION: An outer peripheral surface of vibration-proof rubber 33 is bonded to the inner peripheral surface of a boss 31, the inner peripheral surface is bonded to the outer peripheral surface of a sleeve 32, and the boss 31, the vibration-proof rubber 33 and the sleeve 32 are integrated. After the sleeve 32 is fitted from the lower end into a semicircular part 37a in cross section on the lower part of a rotary shaft 37 of a motor and passes through a through-hole 36, a nut 39 is fastened to a screw thread part on the lower end part of the rotary shaft 37 and the sleeve 32 is mounted on the rotary shaft 37.  Because the nut 39 is abutted on the lower end face of the sleeve 32 and is not abutted on an impeller 30 and vibration proof rubber 33, the vibration proof rubber 33 does not deform and the impeller 30 does not lose its balance, even if the impeller 30 is assembled with the rotary shaft 37 if the impeller 30 is balanced by itself. Therefore, vibration is not generated at the time of revolution of a turbofan 6.

Title: Protection of catalyst by deposit of protective layer
Inventor: DARCISSAC JEAN
IPC: B01J37/02
Filed: 1998-08-11
Abstract: PROBLEM TO BE SOLVED: To materialize the passivation of solid particles by covering the sur face of non-uniform catalyst particles with at least one protective layer consisting of a coating substance. SOLUTION: An obtained oxidation catalyst is introduced into a steel barrel kept at 100 times/min revolution. The barrel is equipped with four units of suction devices which agitate a rotating catalyst surely and a compressed gas spraying nozzle. The whole is heated at 50 deg.C. A solution of 20 wt.% of an acrylic polymer in ethyl acetate is sprayed on the catalyst to deposit the polymer. The molecular size of the acrylic polymer is greater than the minute size of alumina. The control of the nozzle is done so that a medium solvent is vaporized substantially completely in a stroke in which the solvent moves toward the catalyst particles. In this way, the polymer is deposited randomly on the outer surface of the catalyst particles under continuous agitation to avoid any kinds of aggregation due to adhesion.  Thus, a protective layer is formed on all surfaces and on non-uniform places of each basic particle.

Title: Light emitting element driving circuit
Inventor: OGURA YOICHI
IPC: H03K17/78
Filed: 1987-09-10
Abstract: PURPOSE:To reduce the waste of power consumption by comparing a drive current subjected to negative feedback with a reference signal current and controlling the driving current generated from a transistor(TR) circuit is response to the difference signal, thereby improving the stability of the driving current against the temperature change. CONSTITUTION:A feedback circuit 100 for a driving current and a comparator 200 are provided. Then part of the driving current supplied from the TR circuit for drive current generation to the light emitting element is fed back negatively by the feedback circuit 100 and the driving current subjected to negative feedback is compared with the reference signal current by the compartor 200 to control the driving current generated from the TR circuit in response to the difference signal. Thus, even when the driving current generated from the TR circuit attended with a temperature change is varied, a stable driving current subjected to temperature compensation at all times is supplied to the light emitting element and since no large current flows to the circuit when the light emitting diode is not driven, waste of power consumption is reduced.

Filed: 1988-09-12
Abstract: PURPOSE:To simplify the structure and to improve the reliability by switching the rear wheels to the opposite phase or the same phase by action of fluid pressure of a metering cylinder of front wheels. CONSTITUTION:When a steering wheel 11 is turned to the left, for example, a rack shaft 15 and an operation rod 20 are largely moved to the right and a piston 22 is pressed by a stopper 27 to discharge a fluid from a metering cylinder C2. The discharged fluid is introduced into a pilot chamber 35 of a control valve for rear wheels to move a spool 36 to the left. By this operation, a discharged fluid of a pump P for rear wheels is supplied to a cylinder C3 for rear wheels to move a piston 46 to the left. Thus, the rear wheels 47 are steered in the opposite direction to the front wheels 46. When a steering angle is small, no fluid is discharged, and a controller 43 turns the rear wheels 47 in the same direction as the front wheels 14 according to the steering direction. By this arrangement, the structure can be simplified and the reliability can be improved.
