Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To make the creeping characteristic substantially zero by fixing a strain gauge obtained by patterning a metal foil formed of a base member formed of a synthetic resin having a small amount of a filler mixed thereto to the strain generating part of a strain generating body. SOLUTION: The creeping characteristic of this load cell, can be made substantially zero at a rated load of 6 kg or less by fixing a strain gauge 7 obtained by patterning a metal foil formed on a base material 8 formed of a synthetic resin having a small amount of a filler mixed thereto to the strain generating part of a strain generating body. As the synthetic resin used for the base member 7, a polyimide resin is particularly preferred. As the filler, alumina, silica, mica and the like are used. Further, the mixing of the synthetic resin with the filler is performed by mixing a prescribed quantity of the filler powder to a prepolymer solution of the resin followed by stirring and uniformly blending them together, and the base member 8 is obtained by heating and curing the resulting blend while molding into a sheet.

Title: Ic card
Inventor: YAZAWA YOSHIAKI
IPC: B42D15/10
Filed: 1989-09-20
Abstract: PURPOSE:To lengthen the life of a battery in an IC card, and to make the IC card convenient to use by assembling an element whose reflection factor of light is changed by an arithmetic circuit and a drive circuit in an internal part. CONSTITUTION:The element 7 to modulate the reflection factor, a transmission factor or a refraction factor is built in the IC card 1, and by irradiating the element 7 of the IC card to modulate the reflection factor, the transmission factor or the refraction factor by the light of a light emitting element 11 installed in an external input/output device and receiving reflected light, transmitted light or refracted light from it by a light receiving element 10 installed at the external input/output device, the IC card need not be provided with the light emitting element. Thus, since the light emitting element of large power consumption is removed from the IC card, the power consumption of the IC card can be reduced, and since the life of the battery built in the IC card is lengthened, the convenience to use of the IC card can be improved.

Filed: 1983-12-26
Abstract: PURPOSE:To decrease a noise upon switching of a phase current by providing means for smoothing the absolute values of ascent and descent gradients of a current of a coil substantially equally in balance. CONSTITUTION:When a coil driver input (e) is switched from a high voltage to a low voltage, a transistor 8 becomes OFF from an ON state, a capacitor 12 starts charging, and the base voltage of a transistor 9 rises. When the transistor 9 starts conducting, a coil current gradually rises. When the input (e) is switched from a low voltage to a high voltage, the transistor 8 becomes ON, and the capacitor 12 starts discharging. The base voltage of the transistor 9 drops, and the coil currents rises. The absolute values of the gradients of the coil currents between when the coil current turns ON and when the current turns OFF can be substantially balanced by suitably selecting the value of a resistor 11'.
