Title: Turning attitude control method for hanging load of crane
Inventor: YAMAMOTO HARUMASA
IPC: B66C1/28
Filed: 1995-05-23
Abstract: PURPOSE: To attenuate twisting motion developed when a hanging load is in turning motion. CONSTITUTION: A hosting accessory section of a crane A is provided with a hoisting accessory equipped with a turning mechanism driven by a motor, which is located between a hook sheave section and an arresting section fixing a hanging load, an inverter driving a turning motor 6, and with a mechanism issuing a turning speed command to be given to the inverter against a turning angle command. Against the turning angle command, a turning speed pattern producing no twisting when turning is terminated, is formed in advance, the electric motor is driven by the inverter, and development of a twisting angle is thereby suppressed to a minimum extent.  Therefore, based on the turning angle command, since a turning speed pattern producing no twisting when turning is terminated, is formed in advance by combining acceleration/ deceleration with uniform motion based on a characteristic period of twisting, and also since turning is so designed as to be made along the aforesaid pattern, the development of a twisting angle can thereby be suppressed to a minimum extent.

IPC: H01L41/08
Filed: 1978-12-08
Abstract: PURPOSE: To facilitate the formation of a large-diameter output conductor portion in a hermetically sealed container by providing the hermetically sealed container enclosing a piezoelectric element, wherein the pressure apllied to the piezoelectric element is not transfered to the hermetically sealed container.  
     CONSTITUTION: An element stack 4, which is constituted by connecting a plurality of disk-shaped piezoelectric elements 5, is compressed by a compressor 6. An end- plate base 14 and a top plate 15 comprise a rigid structure, and a rigid frame 16 comprises a plurality of rods and are arranged so as to avoid the portions where an output conductor 11 and a voltage divider 12 are provided. When a hydraulic pump 38 is actuated, a ram 36 is pushed up, and a compressing force is applied to the element stack 4 by way of a piston 35. Since the pressure applied to the element stack is not transfered to a hermetically sealed container 8, the structure of the hermetically sealed container can be arbitrarily selected, thereby a large-diameter output-conductor take-out portion 23 for high voltages can be readily constituted.

Title: Thin type battery and pack battery incorporating thin type battery
Inventor: ITO TSUKANE
IPC: H01M2/10
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To surely detect the increase in the internal pressure and prevent the increase in the internal pressure by attaching a strain sensor on the surface of a film external packaging body storing a power generating element having a positive electrode and a negative electrode in an inner hermatically closed chamber. SOLUTION: A strain sensor 8 is extended vertically and adhered and fixed to the surface of a film external packaging body 5. The film external body 5 is vertically extended and easily deformed so that the strain sensor 8 can detect the deformation of the film external body 5 at high sensitivity. When the film external body 5 is deformed to change the resistance value of a strain gage, a wheel stone bridge becomes unbalanced to increase the output voltage. A detecting circuit amplifies the output voltage and inputs it into a control circuit, while the control circuit controls a cut-off switch to cut off the current. It is mainly during charging when the internal pressure of the battery is increased to deform the film external body 5, so that the battery has FET connected in the direction of cutting off the charging current.  This constitution can prevent the battery from being in a dangerous state and improve the safety.
