Abstract: PROBLEM TO BE SOLVED: To achieve a method of manufacturing an interlayer insulating layer which can prevent the continuous growth of pin holes, when preparing a multilayer insulating layer and hence prevent short-circuiting defects between upper and lower interconnection layers, and which can prevent damages such as sagging of layer patterns during sintering and hence prevent defective interconnections. SOLUTION: Element electrodes 1 and 2 are arrayed on a substrate 9 (a), and Y-direction interconnections 4 are formed, while being connected to the electrodes 1 (b). Interlayer insulating layers 51 are formed so as to cross the interconnections 4, and second and third insulating layers 52 and 53 are formed (c). Insulating materials forming the respective layers are such that an insulating material forming the intermediate layer has a lower softening point than those of the uppermost and lowermost layers. Sintering is performed at a temperature, which is higher than the softening point of the intermediate layer 52 and which is substantially equal to the softening point of an insulating material forming the layer immediately thereunder. X-direction interconnections 6 are formed on the uppermost layer 53 (d).  Then, interconnections 7 to be connected to the electrodes 2 are formed, and conductive thin films 3 are formed between the electrodes 1 and 2 (e). During the sintering of the layer 52, the layer 52 softens appropriately, while the layer 51 immediately thereunder is hardly softened.

Abstract: PROBLEM TO BE SOLVED: To make a fire so as not to happen even in such a work environment as deafening a warning by stopping a power supply to a magnetic contactor exciting circuit in the case where a detector has detected abnormality of the operation of a transistor. SOLUTION: A microcomputer 4 outputs an exciting transistor 1C by means of inputting a travel lever equipped in a driver's can of a car body, exciting a magnetic contactor exciting coil 1A.

Title: Alumina-based sagger
Inventor: KATO AKIO
IPC: C04B35/64
Filed: 1993-03-05
Abstract: PURPOSE:To obtain a sagger, excellent in resistances to reaction and spalling and capable of directly placing a material to be burned thereon and burning the material to be burned by adding and mixing andalusite powder having a specific particle diameter with Al2O3 powder, forming raw material powder and then burning the formed compact. CONSTITUTION:Raw material powder prepared by adding and mixing 5-40wt.% andalusite powder having <500mum average particle diameter with Al2O3 powder is used and formed into a desired shape. The resultant formed compact is then burned to produce an alumina-based sagger containing >=80wt.% Al2O3 as the chemical composition. Since this alumina-based sagger is excellent in resistance to reaction and spalling for a material to be burned in burning electronic parts such as a ferrite or a ceramic capacitor, the material to be burned can be placed on the sagger through no setter and burned. Thereby, automation and robotization of a burning line can be carried out without using the setter.

Title: Digital phase locked loop circuit
Inventor: ISHIZUKA KOUHEI
IPC: H03L7/06
Filed: 1984-03-12
Abstract: PURPOSE:To decrease jitters by using a circuit controlling a region (dead band) where an output state of a frequency divider is unchanged with respect to an input signal while phase lock state is attained. CONSTITUTION:It is supposed that a frequency of an input signal is near a frequency applied with 1/m frequency division of a signal from a reference oscillator 5. The phase difference between the input signal at a terminal 1 and the signal from a frequency divider 6 is detected by a phase comparator 3. A frequency dividing number control circuit 4 sets the frequency division numbers of m-1 or m+1 depending on the lead/lag of both and the frequency division number is fixed to only (m) by a dead band control signal obtained via a dead band control circuit 7 at the region of + or -T/2 before and after the divider output rising change point. The output of the oscillator 5 is frequency-divided into a frequency dividing number required for the frequency divider 6 by using the control signal. The output is inputted to the phase comparator 3 and also outputted from a terminal 2 at the same time. Thus, jitters are reduced by the introduction of the dead band in case of the assumption above.

Abstract: PURPOSE:To measure the distance to an accident point with high accuracy by applying a DC voltage to a cable where an accident occurs, finding the waveforms of a current and a voltage in accident phase at the moment of discharging at an accident point, and finding conductor resistance from their waveforms. CONSTITUTION:The cable 1 shown in a figure (a) is short-circuited at a remote terminal 11 in the accident phase 1A and health phase 1B and a DC power source 3 is connected to a measurement terminal 11 in accident phase 1A. Then a DC voltage is applied from the power source 3 and discharging occurs at the accident point when the DC voltage reaches a specific value. At this time, the waveforms of the current I and voltage V are measured and recorded by an A/D converter 4. Then the current I at the time of the discharging flows through only the conductor resistance r1 from the measurement terminal 11 to the accident point X, but does not flow from the accident point X to the remote terminal 10 and health phase 1B. For the purpose, the current I and voltage V are read out of the current and voltage waveforms at the time of the discharging to measure the conductor resistance r1 up to the accident point X. The while the core at the remote terminal 10 in the accident phase 1A is grounded and similar measurement is carried out to measure the resistance of the cable to its overall length, thereby locating the accident point.

Filed: 1995-03-06
Abstract: PURPOSE: To set a constant and accurate catch detection range at all times by measuring motor power voltage, upon arrival at a complete closing position, and making a correction for learning on the basis of a correlation between the value of the voltage and a dead zone. CONSTITUTION: A power window regulator circuit 30, upon judging that the upper end of window shield glass reaches a completely close position and a window shield glass elevator motor 26 is locked, measures the power voltage of a motor 26. A correction is, then, made for learning, on the basis of a correlation between a preliminarily stored power voltage value, and a dead zone from a reference position to a catch detection range, and a position for entering a dead zone corresponding to the measured voltage is thereby established. As a result, a constant and accurate catch detection range can always be determined.

Title: Furnace temperature control method of direct fire type vertical heating furnace
Inventor: NAKAOKA KAZUHIDE
IPC: C21D9/66
Filed: 1979-04-17
Abstract: PURPOSE:To prevent steel strip rupture due to oxidation of the surface by lowering the furnace temperature quickly when stopping the line without requiring special facility as in conventional method, by blowing petroleum and water into the furnace at a specified rate, in controlling the furnace temperature. CONSTITUTION:In controlling the furnace temperature of a direct fire type vertical heating furnace, by blowing petroleum and water at ratio of 1:1-1:5 range by weight, the furnace temperature is quickly lowered, and oxidation of the steel strip surface of carbon deposition scarcely occurs, and the output of flammable decomposition product is decreased. This method is especially effective for lowering the furnace temperature quickly when stopping the line to prevent oxidation of the steel strip which may cause rupture of the steel plate. At the same time, it is economical because only about 0.4-0.1 time of consumption of petroleum is needed as compared with the consumption of methanol to obtain the same cooling effect as in the case of the conventional cooling method with methanol. Besides, no particular care is needed for safe handling.
