Title: Manufacture of display device
Inventor: MINO YOSHIKO
IPC: G02F1/136
Filed: 1997-10-03
Abstract: PROBLEM TO BE SOLVED: To surely fill a contact hole, planarize a substrate surface, and obtain superior coverage of a sputtering film by filling and forming contact metal through a plating method. SOLUTION: A substrate 1 for display is dipped in a plating solution, and first contact holes 21 are filled with a first contact metal 22. When a first etching mask 20 is stripped from the substrate 1, the first contact metal 22 which is superfluous is stripped together with the first etching mask. The first contact metal 22 is self-aligned highly precisely with the inside of the first contact hole 21 and formed with high flatness to a second interlayer insulating film 9. Hence alignment of high precision is performed by using again the first etching mask 20 formed, when the first contact holes 21 are formed. Thereby neither an exclusive mask is needed, nor the number of processes is increased.

Filed: 1985-12-04
Abstract: PURPOSE:To eliminate the possibility of generating trouble with simple construction by throwing an inoculant and ceasing the throwing by means such as triangular stopper according to the forward and backward rotation of a ladle handle. CONSTITUTION:Pouring is started when the titled handle 4 of the ladle is rotated forward. A disk 41 and a cam plate 51 grasped by a torque limiter of an inoculating device are then turned forward, by which the inoculant is supplied to molten metal flow.

Abstract: PURPOSE:Not to compulsorily disconnect the call of a doorphone even when a guest comes to a lobby by switching a speaking circuit from the doorphone to a lobby interphone with the AND between a call signal from the lobby interphone and a hook switch ON signal. CONSTITUTION:When the call signal is inputted from a lobby call terminal 5 in a control circuit 6, the circuit 6 outputs the signal to a ringing tone generation circuit 9 and makes a speaker 11 ring through an amplifier 10.

Title: Overexcitation detecting relay
Inventor: SATO CHIKAO
IPC: H02H7/06
Filed: 1993-10-29
Abstract: PURPOSE:To allow positive detection of an overexcited operating state of a generator, a transformer, etc., by resetting the amount operated at an overexcitation operating section when the decision output from an undervoltage detecting section sustains for a predetermined time or longer. CONSTITUTION:An overexcitation detecting/operating section 12 operates an amount corresponding to the area of AC voltage waveform using the value of AC voltage waveform sampled during the half wave interval thereof or an integer times thereof. An undervoltage detecting section 15 makes a decision whether the sampled value is lower than a preset second constant. When the decision output from the undervoltage detecting section 15 sustains for a predetermined time or longer, a time limit counter 16 resets the amount operated at the operating section 12. This constitution allows positive detection of the overexcited operating state of a generator, a transformer, etc., while preventing erroneous decision due to lowering of operational accuracy in low frequency region caused by the error at the input parts including the A/D converting part.

Title: Detecting system for special common-battery telephone
Inventor: IIJIMA FUMIO
IPC: H04M3/42
Filed: 1984-12-24
Abstract: PURPOSE:To omit a detecting circuit exclusive for common-battery button by using the current polarity inverting means of the line circuit of an automatic converter. CONSTITUTION:A push-button state detecting function is provided to a current polarity inverting means (relay RV, etc.) to inform the answer of a called subscriber within a line circuit 2 to a device at the calling subscriber side such as a facsimile terminal, etc. The relay RV works to invert the polarity when a common-battery telephone with buttons is hooked off if the telephone 1 is set previously so that a current flows to a point B from a point A as shown by a continuous line arrow head. Thus the current flows to the point B from the point A as shown by the broken line arrow head. Here if a push-button 10 is pushed, no current flows toward the broken line arrow head. While the current flows toward the broken line arrow head if the button 10 is not pushed. Thus a call detecting circuit 20 can discriminate the push of the button 10 according to the presence or absence of the current flowing toward the broken line arrow head.

Abstract: PURPOSE: To mount automatically solder chips on a circuit board and to obtain a solder chip mounting device, whose cost is low also from the viewpoint of cost, by a method wherein a robot is actuated in the two directions along the X-axis and Z-axis which is vertical. CONSTITUTION: In an alignment station 12 for aligning solder chips, an inspection station 32 for inspecting a state that the solder chips are suked by a robot 36 and a mounting station 42 for mounting the solder chips on a circuit board 40 are arranged in one row and by transferring the chips by the robot 36 movable in the X-axis direction along this row and the Z-axis direction which is vertical, the chips are automatically mounted. Moreover, as the robot 36 has only to be movable in two directions along the X- and Z-axises, a solder chip mounting device is simplified compared with devices where the robot 36, which is moved in three axial directions, is adopted, and the cost of the device can be lowered.
