Title: Brake control method for inverter crane
Inventor: YAMAMOTO HARUMASA
IPC: H02P3/26
Filed: 1993-08-30
Abstract: PURPOSE:To improve operability of a crane by decreasing its speed by use of a mechanical brake and then again driving a crane by an inverter to enable holding of speed, acceleration or braking by regenerative braking or a mechanical brake. CONSTITUTION:A manually operated ceiling traveling crane includes a V/F control inverter for controlling its traveling speed, an induction motor driven by an inverter, and a mechanical brake arbitrarily operated by a driver. In the case of decreasing the speed by the mechanical brake, the output frequency of the inverter is synchronized with the traveling speed, and the interference of braking of the mechanical brake with the driving torque of an electric motor is eliminated so as to brake and stop the crane.

Title: Roll paper holder and image recording device provided with it
Inventor: TERAO KENJI
IPC: G03G15/00
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent jamming of a material to be recorded and to realize the simple and compact constitution. SOLUTION: When a recording paper discharged from a recording paper outlet 15 is cut off, a recording roller 17 is reversed and brings the tip end of the recording paper close to a thermal head 18. At this time, a roll paper holder 24 is oscillated around a fulcrum 26 due to a recovering force of a spring 28. At this time, a friction force between a loading table 25 and a roll paper 13 makes the roll paper holder 24 rotate the roll paper 13. As a result, the recording paper is wound around the roll paper 13.

Title: Cleaning device
Inventor: TAMURA YOSHIHISA
IPC: B08B3/02
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To efficiently clean a material to be cleaned in a cleaning vessel by forcibly supplying high pressure air to a cleaning liquid tank and jetting a cleaning liquid having bubbles in it into the cleaning vessel through a feeding/ discharging pipe to utilize the jetting flow of the cleaning liquid and the cavitation effect caused by the breaking of the bubbles incorporated therein. SOLUTION: When a blower 29 is operated by driving a blower motor 31, the pressurized air flows in to the cleaning liquid tank 4 through a high pressure air supply pipe 9 from a discharge port 35 to pressurize the cleaning liquid L and the cleaning liquid L flows in to the cleaning vessel 5 through the feeding/ discharging pipe 7. When the water level of the cleaning liquid L is lowered and reaches the same level as that of an lower end opening of the feeding/ discharging pipe 7, the pressurized air forms the bubbles and ascends with the cleaning liquid L in the feeding/discharging pipe 7.  The material O to be cleaned is efficiently cleaned by the multiplier action of the jetting action of the cleaning liquid L and the stirring action of the bubbles with the cavitation effect generated at the time of expanding and breaking the bubbles when the cleaning liquid L, in which the bubbles are incorporated, flows in to the cleaning vessel 5.

Abstract: PURPOSE:To directly measure the fluctuating soil pressure acting on the respective surfaces of the embedment part of a foundation part, the magnitude of the friction of the side surface or bottom surface of the foundation part with an underground surface and a horizontal force allotment ratio at the time of vibration. CONSTITUTION:An underground wall 20 is embedded in a model ground 12 at a predetermined depth of embedment. When this model ground 12 is vibrated, vibrating soil pressure, side surface friction force and bottom surface friction force act on the underground wall 20 crossing the vibration direction of the ground 12 at a right angle and the side surface and bottom plate 18 of the underground wall 12 positioned in parallel to the vibration direction. By the soil pressure and the friction forces, axial tension or shearing force acts on the acrylic rod materials 24, 52, 54 supporting the side surface and bottom plate of the wall 20 to generate distortion. By measuring this distortion by a load cell 30, the horizontal force acting on the respective surfaces of a foundation part can be calculated. When the horizontal force is divided by the inertial force generated in a structure model 12 and a foundation part model 14, the horizontal force allotment ratio of the embedded foundation part can be calculated.
