Title: Liquid kind detecting device
Inventor: OGATA KAZUO
IPC: G01N25/20
Filed: 1990-03-13
Abstract: PURPOSE:To detect the kind of liquid with fast response by providing a liquid kind sensor which detects the quantity of heat radiation by ambient liquid while specific temperature is reached by electric heat self-generation and a temperature sensor which detects variance in the temperature of the circumferential liquid. CONSTITUTION:The temperature detection sensor 3 which has an about 500OMEGA resistance value and the liquid kind sensor 4 which has an about 20OMEGA resistance value are held by a holder 10 in a shield wall 1. Further, a Wheatsone bridge is composed of the sensors 3 and 4 and bridge resistances 5 - 7 and its output is led out by a comparator element 8. The sensor 4 is fed with electricity for 10 seconds to generate heat by itself and stop generating heat after reaching temperature which is 10 - 20 deg.C higher than the temperature of the liquid. Then the sensor 4 varies in resistance value by heat radiation to the liquid and the bridge becomes unbalanced to cause voltage variation. This voltage variation has a constant value determined by the heat capacity of the liquid.

IPC: H03K6/00
Filed: 1986-03-19
Abstract: PURPOSE:To avoid saturation of output despite the large input and to increase a dynamic range by connecting a diode in parallel to a voltage amplifyier circuit and a part of the feedback resistance of a peak holding circuit. CONSTITUTION:The current corresponding to the light quantity detected by a photodetecting element 1 is converted into the voltage by a current/voltage conversion circuit 30 and supplied to a voltage amplifier circuit 41. The negative feedback is applied to the input of the circuit 41 from a peak holding circuit 8 and the output of its own circuit 41. A combination circuit of a diode and a resistance is inserted to the negative feedback path in addition to the feedback resistances 19 and 12. Thus the nonlinear feedback value is secured. Therefore the feedback value is increased with application of an excessive input. Then the gain is reduced to compress the amplitude and therefore the output satura tion is avoided.

IPC: H05K3/46
Filed: 1990-03-13
Abstract: PURPOSE:To make a fine continuity hole quickly with high accuracy and stably by a method wherein, in making the continuity hole in an upper-side conductor layer and a lower-side conductor layer, an opening part is formed in advance in a continuity-hole formation part of the upper-side conductor layer. CONSTITUTION:While a working protruding part 20 is being oscillated at a high frequency, polishing abrasive grains 31 together with water are poured into a part between the working protruding part 20 and a part to be worked of a multilayer electronic-circuit board and the working protruding part 20 is pressed. When the lower end of the working protruding part 20 has reached a conductor layer 6 as a lower-side conductor layer, the high frequency is absorbed because the conductor layer 6 is formed of a soft metal of copper or gold. A hole working operation is finished. The diameter B of an opening part 41 at a conductor layer 4 as an upper-side conductor layer is set to a size between -0.1 to +0.2mm with reference to the diameter A in the working protruding part 20. Since the opening part is formed in advance in the upper-side conductor layer, the hole working operation in the upper-side conductor layer can smoothly be executed.

Title: Liquid crystal display device and its production
IPC: G02F1/1368
Filed: 1992-03-18
Abstract: PURPOSE:To absorb the thickness of a gate line formed by plating by a trench provided in a glass substrate and to drastically decrease the line resistance of the gate line by embedding the gate line into the trench. CONSTITUTION:The trench 4 is provided in the glass substrate 1 and the gate line 12 formed by the non-electric field and electric field plating is embedded into this trench 4. Then, the level difference of the gate line 12 can be absorbed by the recess of the trench 4 even if the gate line is formed thick. As a result, the thick formation of the gate line 12 is possible and its sectional area can be increased and, therefore, the resistance of the gate line 12 is easily decreased. The line resistance can be lowered even in spite of use of metals, such as Cr and Ni, which are high in specific resistance but are inexpensive as the material for the gate line 12. The resist layer for forming the trench 4 is used as a common mask up to the non-electric field and electric field plating of the gate line 12 and, therefore, the production by simple self-alignment is possible.
