摘要： PROBLEM TO BE SOLVED: To provide a load sensor with a structure utilizing a magnetostrictive effect, used for measuring high sensitivity and high accuracy in a region with relatively small loads, and to provide its manufacturing method. SOLUTION: An element of this load sensor is obtained, by forming a layer of a material having a magnetostrictive effect on a surface of a base material made by shaping a nonmagnetic elastic body into a form of a compression coil spring, a tensile coil spring, a torsion coil spring, a leaf spring, a spring washer, a wave washer, a conical spring washer, or the like. When applying load on the element, changes in magnetization due to a deformation thereof is detected, as a change in the inductance by a coil attached to the element. Since the base material has a form causing even a small load to bring about large deformations, a relatively small load can be detected with high sensitivity and high accuracy.

摘要： PROBLEM TO BE SOLVED: To increase a capacitance of an electric double layer capacitor.
SOLUTION: This electric double layer capacitor uses a mixture of different sizes of conductive carbonaceous powder for polarized electrodes. The average size of the power is made 2 to 200 times the other smaller powder and the larger diameter powder is mixed 50 to 95% in weight. This means that a larger amount of the conductive carbonaceous powder can be filled, which increases the powder surface areas resulting in an increased static capacity of the capacitor. The conductive carbonaceous powder can be activated carbon, acetylen black or Ketjen black.
