Title: Digital-analog converter
Inventor: KADAKA TAKAYUKI
IPC: H03M1/78
Filed: 1983-11-12
Abstract: PURPOSE:To minimize the harmonic distortion factor by giving a potential of a half of the sum of two reference potentials Vcc and Vss to a reference bias terminal and a midpoint bias terminal respectively so as to attain an ideal bias state. CONSTITUTION:A bias circuit 20 providing a potential of (Vcc+Vss)/2 to the reference bias terminal 14 and the midpoint bias terminal 16 respectively as bias potentials VT and VM is provided. An analog output VOUT changes around the (Vcc+Vss)/2 so as to prevent a shift of VLSB/2. Thus, the voltage biasing the LSB side termination part of a resistor ladder network LA is nearly (Vcc+ Vss)/2.

Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To recover the toughness of a dual phase stainless steel in an embrittled state by subjected the steel to holding at specific temp. for specific time and then to air cooling. SOLUTION: For example, the toughness of a 316 cast steel (dual phase stainless steel), reduced to about 5kgf.m by aging treatment at 400 deg.C for 3000hr, can be recovered by >=80% of the value at reception by means of heat treatment of heating at 500-600 deg.C for 1hr and air cooling. Moreover, the hardness of ferritic phases, hardened by aging, is reduced by means of heating at 500-600 deg.C. It is preferable to regulate the heating and holding time at 500-600 deg.C to 5min to 2hr. By this method, the deformation of the product to be heated can be prevented because heat treatment is performed at low temp., and further, heat treatment can be carried out leaving a margin for equipment.

Abstract: PROBLEM TO BE SOLVED: To enable a pressure distribution analyzer to automatically analyze the spatial and temporal distributions of a pressure when a moving object grounds. SOLUTION: A pressure sensor 101 measures the pressure distribution which is generated when an object lands and outputs the measured distribution to a bottom face area detecting section 102 and a part load detecting section 104.
