Inventor: MATSUDA MASAO
IPC: G01R31/00
Filed: 1984-04-17
Abstract: PURPOSE:To obtain a linearity error measuring circuit eliminating noise caused by changeover of an input code to a D-A converter by applying an output of a differential amplifier of a D-A converter to be measured and a D-A converter functioning as a reference to a sample-and-hold circuit. CONSTITUTION:An identical code in synchronization with a clock input 7 is fed to the D-A converter 2 to be measured and the D-A converter 3 being a reference from a binary counter 1 to change the D-A converters sequentially. Then outputs of the said two D-A converters are fed to a differential amplifier 4, the output of the differential amplifier is fed to the sample-and-hold circuit 5, and when both the D-A converters are made stable to be in a steady-state, the output is sampled and held, then the result is measured by an oscilloscope 6. Through the constitution above, the noise caused by the changeover of the input code to the D-A converters is eliminated to measure accurately the linearity error of the D-A converters.

Title: Joint for connecting false tooth with bed and tooth
Inventor: HANSU DARA BONA
IPC: A61C13/265
Filed: 1980-06-11
Abstract: A joint for connecting a partial dental prosthesis to remaining natural teeth has a compression spring (10) acting on joint portions (1, 7) displaceable in a sagital direction, which spring relieves the prosthesis (13) connected to one of the joint portions (7) in the unstressed state.
