An apparatus for providing assessment indices related to bone strength which are useful in predicting the risk of bone fracture. The apparatus measures the mineral density of bone (BMD) by means of X-rays, while the propagation speed of sound V in the bone and bone thickness d are measured by means of ultrasonic waves. The bone mineral content per unit volume, i.e. the bone volume density .rho., is computed from the bone mineral density (BMD) and the thickness of the bone. An assessment value E is then computed based on V and .rho..

An electric melting furnace is provided with an exit comprising an overflow dam and a downwardly extending unmolten-substances blocking plate placed inwardly of the overflow dam. The exit is positioned on or near an extension of a line connecting the center O of a furnace body and one of the furnace electrodes, the distance L in centimeters between the electrode and the overflow dam being determined by the equation: ##EQU1## where P is the electric furnace load (w) and K is a constant in the range of 16 to 25. Lighter molten substances are continuously discharged over the dam under the weight of the combustion residue. Heavier molten metals accumulate on the furnace floor and are discharged over dam by tilting the furnace body in the direction of the exit. The furnace has a measuring means placed at an upper interior portion of the furnace for measuring the temperature of the furnace gases and another measuring means placed on the discharge passage for measuring the quantity of the luminous energy radiated by the molten substances. The values obtained by the temperature measuring means and the luminous energy measuring means are compared with respective standard values as set in advance to determine the feeding of the combustion residue. When one or both of the feeding conditions is/are met, a fixed amount of the combustion residue is fed into the furnace by opening a feeding gate.

摘要:
The present invention concerns controlling a potential used to form an electrostatic image for image formation. According to the invention, an electrostatic latent image is formed on an image bearing member using, for example, a potential stored in a memory. The potential of the latent image is detected, and if the potential is not within a specified range, the potential is controlled (i.e., changed) to form another latent image with the changed potential. The latent image is then developed and the density of the developed image detected. In one embodiment, the amount of developer to be replenished is then controlled based upon the detected density and a target potential value, where the target potential value is determined and set based on the detected density and the potential used in the potential controlling step. In a related embodiment, when a result of the potential obtained after termination of a normal image formation process is out of a designated range, potential control is performed after termination of a next normal image formation process.

Electrodes 25 and 26 are formed on the surface of the substrate 21 in each of the element mounting sections 50. A fine metal wire 27 is connected between the electrodes 25 and 26 to form a fuse element. A framework portion 41 surrounds each element mounting section 50, forming a depression 24. The depression 24 houses the fine metal wire 27. A cover member 31 is placed over the top of the framework 41, hermetically sealing the depressions 24. Subsequently, the cover member 31 and substrate 21 are cut together, separating each of the element mounting sections 50 to obtain individual electronic devices.
