Title: Information storage circuit
Inventor: TANIMOTO KAZUNUSHI
IPC: G11C29/00
Filed: 1989-03-10
Abstract: PURPOSE:To prevent a fuse element which is not expected to blow from misblowing by setting the potential at an output node lower than the breakdown strength of a transistor(TR) connected thereto in parallel when the TR of a fuse circuit is on. CONSTITUTION:A disconnection control circuit 1 supplies an H-level signal to the gate of a TR for fuse blowing, e.g. TR Q11 corresponding to an element to be fused in response to a program signal the inverse of P and an address signal ADD and supplies a large current from a current line Vcc to a power line Vss through the TR Q11 to fuse the fuse element F1. A misdisconnection prevention control circuit 2, on the other hand, responds to the signal ADD to supply a control voltage VC to all fuse circuits except the element F1, e.g. the gate of a TR Q22 for fuse prevention. In this case, when TRs Q12 and Q22 for fuse protection are on, potentials developed at nodes N1 and N2 are set lower than the breakdown strength of fuse disconnecting TRs Q11 and Q21. Then when the element F1 is fused, a voltage CV is applied to the TR Q22.

Abstract: PURPOSE:To make an interlaced scanning easy by generating a driving clock signal with signal-processing a horizontal synchronizing signal and using a shift register that progresses a two-stage scanning with one period of this clock signal as a vertical scanning circuit. CONSTITUTION:At a vertical scanning circuit driving circuit 5, a horizontal synchronizing signal PH that is included in a composite video signal PS is separated by a synchronizing separation circuit 8 and one is inputted to a scanning start up signal generating circuit 9 and the other is inputted to a modulator 10. The modulator 10 generates clock signals phi1 and phi2 having polarities which are inverted alternately at every odd and even fields and supplies these signals to a vertical scanning circuit 4 where the shift register that consists of a flip flop 6 and an OR circuit 7 is provided. This shift register operates so that the two-stage scanning is progressed with the one period of the driving clock signals phi1 and phi2 and the interlaced scanning is executed.

Title: Electronic clinical thermometer
Inventor: KITAMURA KENZOU
IPC: G01K7/42
Filed: 1980-04-28
Abstract: PURPOSE: To ensure a quick measurement of the body heat with a small amount of power consumption, by applying the voltage to a heat-sensitive resistance element only when the temperature of heat-sensitive resistance element is lower than a prescribed level and the rate of increase of the output temperature signal is higher than a certain level.  
     CONSTITUTION: The differentiating circuit 3 and voltage comparator 4 detect that the rate of increase is higher than a certain level for the output temperature signal of a bridge circuit consisting of the thermister 1 and converting circuit 2. At the same time, the voltage comparator 5 detects based on the temperature signal that the temperature of thermistor 1 is higher than the level equal to the body heat. Based on the both detection results, the voltage is applied to the bridge circuit from the voltage controlling circuit so that the thermistor 1 is set under a self-heating mode and only when the temperature of thermistor 1 is almost equal to the body heat and the rate of increase of temperature signal is higher than a certain level. As a result, an accurate body heat can be measured in a short time and with a small amount of power consumption.

Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a short circuit between wirings, to improve the reliability, to be made fine by a dry etching, and also to suppress the wiring capacity in a wiring overlap part, by adding a slope wall onto the side surface of a wiring layer of a lower layer of a wiring layer laminated on a substrate through an insulation layer. SOLUTION: Leader lines 27'... are formed on a glass substrate 12 as lower layer wiring, and video lines... are formed on them through an insulation film 26. The slope walls 23 are added to both side surfaces of the leader lines 27' and a dummy pattern D. The slope wall 23 is preferred to be stuck to the side surface of the lower layer wiring, and to be provided with a sectional shape so as to form a slop. Its material quality is preferred to be an insulation body, and by adding such a slope wall 23, the shape of the side surface of the lower layer wiring so as to be sheered to a rectangular shape is mitigated remarkably, and the matter that the film thickness of the insulation film 26 coating this part becomes locally thin is prevented. Thus, it is prevented that the lower layer wiring 27' and the D are short-circuited with upper wiring 62.
