Abstract: PURPOSE:To prevent a wafer face or production facilities from being contaminated with a residue of a first metal wiring film by a method wherein, in a scribing line part, the first metal wiring film is etched in such a way that the residue of the first metal wiring film is left so as to cover a stepped part of a first interlayer insulating film along the stepped part. CONSTITUTION:A patterning operation of a first metal wiring film 13 is executed in such a way that, in a scribing part 3, a residue 14 of the first metal wiring film is left so as to cover a stepped part 12 of a first interlayer insulating film 10 along the stepped part 12 of the first interlayer insulating film. When the residue 14 of the first metal wiring film is left to be thick and long along the stepped part 12 of the first interlayer insulating film, a close contact property between a semiconductor substrate 6 and the residue 14 of the first metal wiring film is made strong. By this setup, it is possible to avoid a situation that the residue of the metal wiring film is stripped off from the stepped part of the interlayer insulating film and that a wafer face and production facilitied are contaminated with the residue.

Title: Lead acid battery
Inventor: OKADA YUICHI
IPC: H01M10/06
Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To improve both low temperature high efficiency discharge characteristics and service life performance by including a specific amount of lignin and Ni in a negative pole active material. SOLUTION: In the lead acid battery, lignin of 0.5 to 1.0wt.% and Ni of 0.001 to 0.005wt.% are included in the negative pole active material. To the extent of a drop of charging current reception due to the addition of a lot of quantity of lignin, Ni is added to compensate for charging current receivability. Therefore, the effect of an expander can be maintained for a long period without dropping its charging current receivability. By setting the quantities of lignin and Ni within the range, synergistic effect of both of them can be exhibited to the maximum extent. As an example of additive Ni, nickel sulfate, nickel metal powder or particles may be employed. As an additive agent other than lignin and nickel, barium sulfate and carbon may be added.

Title: Input/output device control system
Inventor: ARIYASU MASAHIKO
IPC: G06F13/14
Filed: 1992-11-24
Abstract: PURPOSE:To provide an input/output(I/O) device which is never hung up by the wait for a ready signal in response to this ready signal even when an access is given to an unmounted I/O device by providing an I/O control part which transmits the ready signal and an unmounted I/O device detecting signal to a microprocessor. CONSTITUTION:When a CPU 4 has an access to an unmounted I/O device 3, a transmitted address is decoded by an I/O control part 5 and a selection signal 14 is transmitted for an I/O device 3. However, the access processing of the CPU 4 is not carried out since the device 3 is not mounted yet. Under such conditions, the part 5 decides an access given to the unmounted device 3 based on a detection signal 18 for the device 3. Then the part 5 produces a ready signal 15 to answer the CPU 4. At the same time, an NMI signal 19 is sent to the CPU 4 so that a fact that an access has just been given to the unmounted device 3 is informed. Thus, the CPU 4 completes the access to the device 3 and is never hung up by the wait for the signal 15.

Title: Color information operating processor
Inventor: TSUDA MITSUHIRO
IPC: G06T1/00
Filed: 1988-12-12
Abstract: PURPOSE:To reduce the memory capacity of a reference table to be required for the execution of arithmetic processing by constituting the reference table so that the arithmetic processing is executed based upon rough gradations in a signal level area in which extremely fine gradations is not required. CONSTITUTION:When a signal value to be converted is inputted, its corresponding operation signal value is found out by retrieving a separation table means 10 and a partial space label name including the signal value is found out by retrieving a label table means 20. Then, the corresponding converting signal value can be found out by retrieving an operation table means 30 in accordance with the found operation signal value and partial space label name. When the converted signal value of a Di signal in color information is a large value, the converted signal value is compressed to a signal value with a rough gradation to execute arithmetic processing, and when the converted signal value is a small value, the converted signal value with a fine gradation is directly used to execute the arithmetic processing. Consequently, the memory capacity of the reference table is sharply reduced.

Abstract: PURPOSE:To omit an external pin that sets only an internal mode by providing the internal mode setting storage circuits on the data and address pins in a normal operation mode, latching the signals inputted from those external pins in the storage circuits, and using the output signals received from these storage circuits as the internal mode setting signals. CONSTITUTION:In a normal mode the data inputted via a data pin 19a are latched synchronously with a clock signal and fetched by a microprocessor via a data input line 21b. Then the processed data are outputted via a data output line 21a and taken out via the pin 19a. In a test mode an internal mode setting signal is inputted via the pin 19a synchronously with a resetting signal 20 and then latched by a storage circuit 25 added to the pin 19a. The output signal 24 of the circuit 25 is used as a scan path selecting signal. Thus it is possible to omit an exclusive external pin that sets an internal mode.

IPC: H04N21/4405
Filed: 1991-11-28
Abstract: PURPOSE:To ensure the ciphering service with respect to a specific contractor by allowing the position of a horizontal descramble window to follow a timing deviation and implementing a stable descramble operation even when the horizontal synchronization period of a scramble signal is deviated from a regular timing. CONSTITUTION:A reset switching control circuit 9 is started by a detection section of a scramble identification detection circuit 1, the clock of a crystal oscillator circuit 7 is counted till a descramble operation is made stable and a reset switching command signal is outputted to an external internal reset changeover circuit 8. The circuit 8 changes over a reset signal by a horizontal synchronization timing signal into an external reset signal to a horizontal synchronization counter 4 according to the reset switching command signal. Thus, since the horizontal synchronization timing by the counter 4 and a horizontal synchronization timing generating circuit 5 follow to the horizontal synchronizing signal of the scramble signal, the timing deviation of the horizontal descramble window signal with respect to the scramble signal is avoided.

Filed: 1993-11-19
Abstract: PURPOSE:To enhance fluidity at the time of injection molding and to prevent the lowering of mechanical strength by heating and melting a molding resin under specific conditions at the time of the injection molding of polycarbonate with a specific mol.wt. containing a carbon filler. CONSTITUTION:Polycarbonate(PC) with a mol.wt. of 16,000-35,000 containing 5-40vol.% of a carbon filler is heated and melted in an atmosphere containing 90vol.% or more of inert gas and the temp. of polycarbonate is set to 320-380 deg.C to perform injection molding. When the carbon filler is added to PC medium or low in fluidity, the fluidity of PC becomes bad. When the temp. of the molten resin is raised, the effect of thermal oxidative deterioration of this PC is increased as compared with glass filler-containing PC and the mechanical strength thereof is lowered. However, when this PC is heated and melted under the above mentioned conditions to be subjected to injection molding, the fluidity thereof is enhanced and a molded product having a thin-walled part can be molded without lowering mechanical strength, especially, the flexural modulus and bending strength.
