Title: Circuit board with capacitive device
Inventor: OYAMADA TAKESHI
IPC: H01L27/04
Filed: 1997-07-10
Abstract: PROBLEM TO BE SOLVED: To precisely control an electrostatic capacitance value of a thin-film capacitive device to a desired value, by attaining a specific roughness in the surface of an insulating substrate where at least the thin-film capacitive device is formed. SOLUTION: Two thin-film capacitive devices 3a and 3b are formed on the upper surface of an insulating substrate 1. The thin-film capacitive devices 3a and 3b respectively comprise a thin-film lower electrode layer 5, a dielectric layer 6 on the layer 5, and a thin-film upper electrode layer 7 on the layer 6. The insulating substrate 1 has a flat surface where the surface roughness in regions of the thin-film capacitive devices 3a and 3b is Ra<=0.1 μm (Ra: the center-line average roughness). In this structure, in a case where the thin-film lower electrode layer 5 is formed by adopting a thin-film formation technique on the insulating substrate 1, the thin-film lower electrode layer 5 has a uniform thickness all over the layer.  Further, the thickness of the dielectric layer 6 and that of the thin-film upper electrode layer 7 formed on the thin-film lower electrode layer 5 are uniform.

Title: Semiconductor integrated circuit
Inventor: TANAKA KOUICHI
IPC: H01L21/60
Filed: 1983-10-04
Abstract: PURPOSE:To obtain an IC having mutual interference between circuit blocks by connecting pads of monolithic semiconductor chips at the same potential via metallic wirings, and connecting the islands to one or more leads via other metallic wirings. CONSTITUTION:Independent ground potential pads 50-53 of amplifiers A1-A4 are connected to an island 21 via metallic wirings 40-43. Since the common impedance of the island 21 is 10mOMEGA or less, it can be ignored, a common impedance is the sum of the resistances of metallic wirings 44 and leads 34, and can be readily reduced to 0.3OMEGA or less. When the wirings 44 are connected in parallel, crosstalk property can be further improved. According to this construction, the crosstalk can be reduced without increasing the chip size, and it is very effective for an IC having multiple functions.

Title: Installation control method for printer information
Inventor: IWASA KEI
IPC: B41J29/38
Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To save an operator from the work of installing printer information from a floppy diskette by communicating with a printer and taking in printer information from the printer only at the time of discriminating it as the result that printer information is not stored in the storage device of the host. SOLUTION: A PPD file is preliminarily stored in the memory of the printer. When the power source of the printer is turned on, the printer transmits a signal to a host computer. The host computer confirms whether it already has the PPD file of the printer or not; and if it has not the PPD file of the printer, it transmits a signal. After receiving this signal, the printer transmits the PPD file. The PPD file transmitted from the printer is taken into the memory in a PC and is stored. If the host computer already has the PPD file, the host computer doesn't return the signal to the printer. In this case, the printer doesn't transmit the PPD file.

Title: Dither read circuit
Inventor: KUROSAKI TOMOYUKI
IPC: H04N1/40
Filed: 1988-07-27
Abstract: PURPOSE:To set an optimum dither slice level in response to the state of an original picture or the like by providing an adjustment means varying an offset voltage of an output to an I/V conversion circuit. CONSTITUTION:The adjustment means provided to the I/V conversion circuit 5a acts like varying an offset voltage of an output of the I/V conversion circuit 5a. An input terminal of a reference potential of the adjustment means uses two resistors R5, Rv to divide the voltage when the I/V conversion circuit consists of an operational amplifier 51 and at least one of them employs a variable resistor Rv. Thus, the offset voltage is fixed as 0V in a conventional circuit, but the adjustment means can vary the said offset voltage to set an optimum dither slice level VSL. Thus, the optimum dither slice level is set optionally.

Title: Program circuit
Inventor: TANIZAKI HIROAKI
IPC: G11C29/00
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To prevent a sub threshold current from flowing between two nodes by setting a transistor between the judgment node and the grounding node which is turned on in a standby state and turned off in an active state. SOLUTION: An N-channel MOS transistor QNL is connected between a judgment node N and a grounding node Vss and is turned on/off in response to a bank activation signal RASX. When the bank activation signal RASX from a bank decoder is an H level, the program circuit is in a standby state. At this time, a voltage of the judgment node becomes a ground voltage Vss and a P-channel MOS transistor QPH2 receiving an inverting voltage of the judgment node N is turned off. As a result, a source voltage and a drain voltage of an N-channel MOS transistor QN0a-QNna, QN0b-QNnb become equal to each other, so that a sub threshold current dose not flow between the judgment node N and the grounding node Vss.

Abstract: PURPOSE:To sense a precise focusing condition without being influenced by the directionality or periodicity of patterns, which are projected on an object to be measured, by determining the contrast on the basis of the difference in the brightness between adjoining picture elements of an image concerned. CONSTITUTION:Image signals from a video camera 12 are A/D converted and stored in an image memory 24 picture by picture. Among the data stored in the memory 24, the image data in the local region where focusing takes place is extracted by a local region extracting circuit 26. A contrast calculating circuit 28 calculates the contrast as n'th power sum of the difference in the brightness between adjoining picture elements in the focusing region, where (n) is integer 2 or more. A memory 30 stores Z-position signals of the video camera 12 given by a position sensor 16, while a peak determination circuit 32 determines the peak of the contrast calculated position by position by means of the minimum square method while the Z-position of camera 12 is changed. A position determination circuit 34 determines the position of the surface of a work 10 from the focal distance of a lens 13 and the Z-position of the camera 12 corresponding to the peak of the contrast.

Filed: 1989-07-18
Abstract: PURPOSE:To improve the sensitivity of a measurement of a deflection angle by calculating the deflection angle according to the distance between the fixed end of a conductive thin wire and a conductive ring and the diameter or the conductive ring. CONSTITUTION:A power supply part 23 is controlled under the command of a CPU 20 to apply a constant voltage between the conductive thin wire 15 and conductive ring 18. Then when the ring 18 is moved down to contact the thin wire 15, the ring 18 is stopped and a process which calculates the deflection angle according to the distance between the fixed end 15a of the thin wire 15 and the ring 18 and the diameter of the ring 18 is performed automatically. Thus, an operator need not view the thin wire 15, so the thin wire 15 can be made sufficiently thin and lightweight. Therefore, even if a lateral flow rate is small, the thin wire 15 is slanted large to improve the measurement sensitivity as to the deflection angle.
