Abstract: A pressing operation body includes an inversion spring having a dome shape; and a rubber stem configured to bend in response to pressing and press the inversion spring. The inversion spring includes a dome portion, and a plurality of leg portions that are extended outward from an outer peripheral edge of the dome portion. The rubber stem includes a base portion configured to support a lower edge of the rubber stem. The base portion includes a plurality of retaining portions configured to retain the plurality of leg portions of the inversion spring.

Abstract: A recording medium includes a sensor circuit unit generating a current in accordance with a blood glucose level in blood, and a control unit calculating blood glucose level data from the data obtained by digital conversion of the generated current at signal processing unit, writing the calculated data to an EEPROM as a memory unit, reading the blood glucose level data from EEPROM and transmitting the same to a portable terminal on which recording medium is mounted, through a communication control unit. The recording medium further includes a power supply control unit receiving power from the portable terminal on which the recording medium is mounted, and supplying power to various portions in the recording medium.

Abstract: The present invention provides a conductor composition that can form a conductor pattern having a good shape precision and a method for producing an electronic component using the composition. This conductor composition contains an organic vehicle, and a conductive powder (typically Ag powder) made of a noble metal or an alloy based on a noble metal, contained in a mass ratio of 80 mass % or more in the conductor composition, and having an average particle size of 0.8 ?m or less, and a ratio (D50/Dmin) of the medium value D50 of the particle sizes to the minimum value Dmin of the detectable particle sizes of 5 or less. This conductor composition has preferably a ratio (V1rpm/V10rpm) of the vicosity V1rpm 1 rpm and the viscosity V10rpm 10 rpm is in the range from 2 to 5.

Abstract: Personal injector for liquid medicine comprises a housing provided with needle-mounting part, medicine container holder and connecting port to a personal computer; plunger arranged in housing; electric motor for driving plunger; limit switch for limiting the forward movement of plunger; starting point sensor for detecting return of plunger to the starting point; and substrate having display and mode-select switch mounted thereon. The plunger is movable between the starting point and forward limit point. Limit switch is arranged at the forward limit point. When limit switch is turned on, motor drives plunger in reverse to move it to the starting point thereof.

Abstract: The present invention provides a conductor composition that is prepared in the form of an ink or a paste and is for forming conductor films having excellent heat resistance on a piezoelectric ceramic material. This composition comprises a platinum powder that is a principal conductor-forming component, and a rare earth oxide powder having a mean particle size in a range of approximately 10 to approximately 100 nm.
