Filed: 1982-12-13
Abstract: PURPOSE:To absorb the vibration from a floor efficiently, without yielding deflection when a measuring machine is operated, by setting the center of gravity of an entire supporting frame including the measuring machine at the attaching position of an elastic member by a means for adjusting the center of gravity. CONSTITUTION:A mounting table 1 is set on a floor, and legs 35 of a measuring machine 34 are mounted on three leg receiving members 36 of a supporting frame 3. The weight of a weight 40 is adjusted by a center of gravity adjusting means 39. The center of gravity of the entire body of the supporting frame 3 including the weight of a measuring machine 34 is set at the height level of vibration preventing tools 2. When the measuring machine 34 is operated, a force in the compressing direction is applied to vibration preventing rubber 21.

When the foregoing double face pressure-sensitive adhesive tape bonded through the water-soluble pressure- sensitive adhesive layer thereof to an adherend is peeled from the adherend, the base material excellent in water resistance is not broken because the water- soluble pressure-sensitive adhesive is dissolved in water upon contact with water to make the tape easy of peeling. Even when the tape is wound around a paper tube, no piping creases are formed. Further, since the water-soluble pressure- sensitive adhesive is used, heating is unnecessary during peeling of the tape. Accordingly, no heat distortion is caused in a molded item.

Title: Current amplification ratio compensation circuit
Inventor: CHIGIRA HIROKAZU
IPC: H03F3/343
Filed: 1992-08-18
Abstract: PURPOSE:To automatically compensate output current even if a current amplification ratio fluctuates by setting the gain of an amplifier whose gain is decided in accordance with current flowing in the collector/emitter path of a transistor to be constant. CONSTITUTION:When the current amplification ratios of the transistors 6 and 11 deteriorate, base current increases by the reduced quantity of the collector current of the transistor 11, and the voltage of an output terminal 17 rises by the quantity. Then, the base current of the transistor 6 increases. The base current is generated in accordance with the fluctuation of the current amplification ratio. When it is generated by same IC, the fluctuation quantity of the current amplification ratios of the transistors 6 and 11 are almost equal and therefore base current becomes compensation current against the transistor 6. Namely, the current amplification ratios of the transistors 3 and 4 are similarly deteriorated when the current amplification ratios of the transistors 6 and 11 are deteriorated. Thus, the gain of the differential amplification circuit 2 can be set constant when the collector compensation current of the transistor 6 is largely set by previously expecting the deterioration.
