Abstract: A noncontact type tonometer projects a fluid toward an eye-to-be-tested and obtains a measured value of eye pressure from a relation between transfigurations of the eye due to the fluid projection and the pressure projecting of the fluid. A detecting circuit senses a pulse wave of the person-to-be-tested and a calculating circuit determines at least one of the maximum eye pressure value, minimum eye pressure value and average pressure value of the eye dependent on the maximum fluctuation width of the detected pulse wave, a fluctuating quantity of the detected pulse wave, and the measured eye pressure value. The calculation circuit determines the pulse wave fluctuating quantity at the time point when the eye pressure is measured. The pulse wave of the person may be measured at a position remote from the eye. The tonometer may also include a display for displaying the pulse wave and a display controller for displaying the time point when the eye pressure is measured.

Abstract: A barcode printer is provided constructed out of rectangular, extruded aluminum stock. The mechanical components are mounted directly to the stock frame of a main housing section which eliminates the need for a separate internal mechanism housing and an external cosmetic housing. The motor is mounted approximately in the center of the unit and along with a plastic enclosure assembly, acts as a spindle for a roll of printing media. This orientation of the motor maximizes its utility and contributes to the compactness of the unit. A full roll of printing media is loaded into the unit by removing a cap which covers the side of the roll of paper and provides see-through availability for determining the amount of stock remaining. The printhead is lifted off the platen (drive) roller and the paper will then slide on and off the spindle. The printhead lifting mechanism includes a printhead dial rotatably mounted on the frame and secured with a retaining ring.

One of the dynamic dampers are provided with elastic members disposed at both ends thereof, only one of the elastic members has an engaging groove going round the outer surface thereof, and the inner diameter of one of the elastic members is made larger than that of the other elastic member.

Abstract: Conductive metal powders having high conductivity with minimized silver migration are characterized in that an average composition is represented by Ag.sub.x M.sub.1-x (wherein M is at least one metal selected from Ni, Co, Cu and Fe; 0.01.ltoreq.x.ltoreq.0.4) and has a region wherein a silver concentration progressively increases on moving from the inner part toward the surface. The conductive metal powders, which are useful as leads, electrodes and shielding from electromagnetic interference are prepared by solidifying rapidly a molten metal having the specific composition.

Abstract: In an internal combustion engine with a supercharger, a timing or timings for varying characteristics of kinetic supercharging effects of intake air are synchronized with a timing or timings for varying supercharging pressures by the supercharger. Reduction in engine torque at the time when the supercharging pressure is shifted, can be compensated for by enhancement in the engine torque generated at the time when the characteristics of the kinetic effect are varied.
