Title: Formation of contact hole of semiconductor device
Inventor: RI KAIO
IPC: H01L21/311
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a contact hole of semiconductor device that can improve the profile of the contact hole when a capping layer for prevention of moisture absorption is formed on an interlayer insulation film made of an SOG(spin on glass) layer. SOLUTION: A capping layer is formed on the upper part of an SOG layer 3. A photo resist pattern 5' is formed on the upper part of the capping layer. While the photo resist pattern 5' is used as a mask, the capping layer and SOG layer 3 thereunder are subject to wet etching and dry etching in order to form contact holes. Then the photo resist pattern 5' is removed. The part projecting from the edge of contact hole is removed through Ar-ion etching. Thereby a contact hole having smooth profile can be formed and no void is generated when the contact hole is filled with a metallic layer 6.

IPC: G06K9/38
Filed: 1985-10-23
Abstract: PURPOSE:To obtain the binary coded signal with no dependence on the input picture signal by detecting both the maximum and minimum values of the picture input signal to compare them with the present picture signal value and then with the upper and lower levels of the picture signal set previously to deliver the binary coded output. CONSTITUTION:A maximum point is detected when the present density is kept between the lower and upper limit levels YL and YU together with the present binary coded output Vout kept at 1. Thus the threshold level is set at the position where the reduction is given from the maximum point by the fixed value CDEC or less. Then the output Vout having the density lower than said threshold level is set at 0. A minimum point is detected when the present output Vout is kept at 0. Then a threshold level is set at the position where the increase is given from the minimum point by the fixed value CINC or more. The output Vout whose density higher than said threshold level is set at 1. If the present density is higher than the value YU, the output Vout is forcibly set at 1. While the output Vout is forcibly set at 0 when the present density is lower than the value YL respectively.

IPC: F02D41/16
Filed: 1987-09-24
Abstract: PURPOSE:To make it possible to surely turn off electricity and keep it turned off by, when an auxiliary air control device is detected to be abnormal, fusing a fuse connected in series to a valve driving part of an auxiliary air control valve. CONSTITUTION:A control device 6 judges an abnormality of a control system from a self-diagnostic result obtained through an abnormality detecting routine. When the abnormality has been judged, a transistor 15 for turning off electricity is turned on, and a relay coil 14b of a totaly enclosed relay 14 is thereby turned on to close a relay contact 14a. Thus a prospective current flows through a fuse 13 to fuse it. After fusing the fuse 13, solenoids 5a, 5b of an auxiliary air control valve 5 are turned off, and its turned off state is kept. A fail safe mechanism thereby functions surely at the time of runaway of the control device 6 on and after second time, and moreover its functioning state is kept. In addition to that, the fail safe mechanism can be surely kept in operative or inoperative state.

Filed: 1990-09-07
Abstract: PURPOSE:To eliminate disturbance of a picture in the vertical blanking period by supplying delay video data to a display panel except in the vertical blanking period of real-time video data. CONSTITUTION:Video data of lower 3 bits out of 4-bit video data inputted from an A/D converter 12 to a control circuit 14 is directly inputted to a segment side driving circuit 15 in real time, and the most significant bit is delayed by about 1/2 field and is inputted. That is, the common electrode of a liquid crystal display panel 17 is selected twice in one field, and a common electrode select signal Xn to select video data of lower 3 bits is applied to this common electrode at the first time, and a common electrode select signal Xm to select video data of the most significant bit is delayed by about 1/2 field and is applied to the common electrode at the second time. Since video data of the most significant bit is not selected in the vertical blanking period of real-time video data, when a basic clock is unstable, in this manner, disturbance of the picture in the vertical blanking period is eliminated.

Title: Checking circuit of residual capacity of battery
Inventor: TSUKUDA YOSHIHIRO
IPC: G01R31/36
Filed: 1987-09-25
Abstract: PURPOSE:To prevent a variation in a battery voltage from affecting a load even when the residual capacity of a battery is checked by a flow of a large current therethrough, by a method wherein the backflow of a voltage on the lead side onto the battery side is prevented by a backflow preventing means provided on a power line. CONSTITUTION:A current from a battery 1 is supplied to a load 2 through a diode (D) 6, and a voltage of the battery 1 is accumulated in a capacitor 3 through (D) 6. Since the load 2 designed to operate with a relatively low current, the voltage of the battery 1 drops little. When a transistor (T) 42 is turned ON momentarily by a control circuit of the load 2 so as to enlarge this little drop of the voltage for detection, a large current flows from the battery 1 through a resistor 41 and T 42. Consequently, the voltage of the battery 1 drops to a battery voltage caused by the large current. Accordingly, the residual capacity of the battery 1 can be checked by detecting the state of the drop of the voltage thereof by a voltage detector 5 in the above-stated condition. By connecting (D)6, a backflow preventing means, between the battery 1 and the load 2, a false operation of the load 2 due to the effect of the lowered voltage of the battery 1 can be prevented.
