Title: Internal bus test easing circuit and method for controlling bus constitution circuit
Inventor: HIKIMA HITOSHI
IPC: G06F11/22
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect a failure in a bus constitution circuit by an automatic test pattern generator(ATPG). SOLUTION: A judging circuit 50 judges whether there is the fear of generation of a bus fight in the bus constitution circuit or not, and when there is the fear of a bus fight, generates a 1st detection signal. A bus fight preventing circuit 30 suppresses data input signals DT1 to DTN in response to the 1st detection signal and supplies a 1st fixed value to the input terminals 11a to 1Na of three-state elements 11 to 1N instead of these signals DT1 to DTN. The circuit 50 judges also whether a bus float occurs in the bus constitution circuit or not, and when the bus float occurs, generates a 2nd detection signal. A bus float preventing circuit 40 gives a 2nd fixed value to a bus line 20 in response to the 2nd detection signal.

Filed: 1977-12-02
Abstract: PURPOSE: To reduce over-shoot and temp. ripple, by means of using thermosensing elements different in two temp. characteristics which control the positve side and the negative side of AC respectively.  
     CONSTITUTION: When AC source is impressed on the terminal of AC source, and a temperature T of a heat load 1 is first T<T2<T1, thyristors 3, 13 become to ON, because thermosensing thyristors 2, 12 are OFF. When the temp. T of the heat load 1 becomes to T2<T<T1, only the thyristor 12 becomes to ON, and current is flowed only during positive half cycle via the thermistor 3 in the heat load 1. And when the tmep. is raised, and the temp. becomes to T2<T1<T, the thermosensing thyristor 2 becomes also to ON and the thyristor 3, 13 become equaally to OFF, and current shall not be supplied to the heat load 1. The temp. of the heat load 1 generates overshoot owing to the thermal inertia, but the quantity is a little, because the supplied power becomes to half.
