IPC: H01C7/02
Filed: 1990-10-22
Abstract: PURPOSE:To prevent a second polymer from being bridged at a first mixing operation and to enhance the quality and the yield of a resistor by a method wherein moisture which has adhered to the surface of conductive powder is removed in a process to form a first mixture and, after that, the second polymer which is bridged by moisture is mixed with the first mixture. CONSTITUTION:In the manufacturing method of a resistor provided with a PTC characteristic, a first polymer which is not bridged by moisture is mixed with conductive powder and a first mixture is obtained. At this time, moisture which has adhered to the surface of the conductive powder is evaporated by heat and friction when the powder is mixed. Then, a second polymer which is bridged by moisture is mixed with said first mixture; a second mixture is obtained. Since moisture has not adhered to the surface of the conductive powder at this time, the second polymer is not bridged. The second polymer in the second mixture is bridged by moisture. As a result, the resistor can be formed without any trouble, the resistivity of the resistor can be formed according to a design value, and the quality and the yield of the resistor can be enhanced.

Filed: 1988-11-07
Abstract: PURPOSE:To detect an accurate steady-state phase abnormal error without the effect of the deviation in elements, the temperature and secular change by generating a threshold level for detecting a steady-state phase error and abnormality with use of digital components only. CONSTITUTION:A phase locked loop oscillation section 20 consists of a phase comparator 1, a voltage controlled oscillator 2, and a frequency divider 4, which form an oscillation loop. In order that the phase locked loop oscillation section 20 detects a steady-state phase abnormal error, a 1st phase clock signal is led for the phase by (t) with respect to a 2nd phase clock signal and the 3rd phase clock signal is retarded by only the phase (t). The phase difference (t) is a threshold level for the detection of a steady-state phase abnormal error and depends on the phase difference of a 3rd phase clock signal. Moreover, a 3-phase clock generating circuit is formed by a digital circuit only depending on the period of the clock signal only. Thus, the detection of the steady-state phase error is attained without the effect of the deviation in the capacitance of components, the temperature characteristic and secular change.

Title: High-breakdown volage semiconductor device
Inventor: KAWAGUCHI YUSUKE
IPC: H01L29/78
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain low ON resistance and to realize high breakdown voltage in both ON and OFF states of a gate at the same time. SOLUTION: This device has the following structure. When a gate is off, an n-type offset layer 14 acts as a reserve and realizes a high breakdown voltage. When the gate is off, even if the electric charge of the n-type first offset layer 14 is offset by the drain current (ID) flowing through an element by the low ON resistance, an n-type second offset layer 15 having a higher dosage n2 than the dosage n1 of the n-type first offset layer 1 acts as the reserve. In this case, letting the amount of the electric charge of electrons be represented by q [C] and the drift speed of carrier be υdrift [cm/sec], the relationship of n2 >=1D/(q.υdrift ) [cm<-2> ] is satisfied.
