  • Device for clamping a workpiece
    Patent number: 5330168
    Abstract: A clamping device which holds a workpiece at a predetermined position during a machining operation of the workpiece comprises a clamper for clamping a workpiece, a feed device for moving the clamper in the axial direction, a load sensor which is fixed to the clamper and detects a clamping force acting on the workpiece, and a memory in which a target clamping force corresponding to the shape of the workpiece and a method of machining operation is stored. The control device compares the clamping force detected by the load sensor with the target clamping force stored in the memory and controls the clamper in response to the deviation between the detected clamping force and the target clamping force. The clamping device also has a position detecting means for detecting the axial position of the clamper.

  • Active suspension with variable roll rigidity distribution ratio
    Patent number: 5253174
    Abstract: In order to improve both the stability of the vehicle during a normal turning such as a lane change and the manoeuvrability of the vehicle during a high transverse acceleration turning, in an active suspension having an actuator adapted to increase or decrease vehicle height at the corresponding portion so that the rolling of the vehicle body is suppressed by a control of the actuator carried out in response to transverse acceleration of the vehicle body, the roll rigidity distribution ratio is shifted toward rear vehicle wheels according to increase of the loads on the vehicle wheels at the outside of the turning.

  • Photosensitive thermosetting resin composition and method of forming solder resist pattern by use thereof
    Patent number: 4943516
    Abstract: A photosensitive thermosetting resin composition, comprising (A) a photosensitive prepolymer containing at least two ethylenically unsaturated bonds in the molecular unit thereof, (B) a photoinitiator, (C) a photopolymerizable vinyl monomer and/or an organic solvent as a diluent, (D) a finely powdered epoxy compound containing at least two epoxy groups in the molecular unit thereof and exhibiting sparing solubility in the diluent to be used, and optionally (E) a curing agent for epoxy resin, excels in developing property and sensitivity and enjoys a long shelf life.By subjecting this photosensitive thermosetting resin composition to coating, exposure, development, and postcuring, there can be formed a solder resist pattern which excels in adhesion, insulation resistance, resistance to electrolytic corrosion, resistance to soldering temperature, resistance to chemicals, and resistance to plating.
