Title: Clocked comparator
Inventor: KONNO YOSHIAKI
IPC: H03K5/08
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To obtain a clocked comparator which is capable of a high-speed operation and prevents a consumption current from depending on a power-supply voltage by adjusting the supply current of a variable current source. SOLUTION: A consumption current is decided by a supply current i0 of a variable current source 31 when a switch control signal ϕ1 is on a high level, that current becomes maximum when a switch control signal ϕ2 is on a high level is at the time when Vin=Vref, and the current is the same as a consumption current when the signal ϕ1 is on the high level. This is decided by the variable current source 31 and is not changed by the fluctuation of a power supply voltage. Further, it is possible to optimize power consumption when the current is set to a minimum value needed to achieve a requested operation speed by adjusting the supply current i0 of the variable current source 31. Further, an operation becomes fast because both a P type MOSFET 15 and an N type MOSFET 17 contribute to Vout fluctuations.

Title: Method and apparatus for inspection of airtightness defect of airtight container
Inventor: HAMADA RYOICHI
IPC: G01M3/26
Filed: 1998-10-22
Abstract: PROBLEM TO BE SOLVED: To detect an airtightness defect easily and in a short time with a simple and low-cost apparatus by a method, wherein the opening of a deformable enclosure is brought into close contact with a face to be detected, so as to be pressed and the collapse size of the face to inspected, which is collapsed due to air pressure in the inside of the enclosure, raised due to the deformation of the enclosure. SOLUTION: A bellows 5 is brought into close contact with the surface of a lid body 2 as a face to be inspected, and a chamber 6 is pressed downward. Then, the air pressure inside rizes, and the surface of the lid body 2 collapses. At this time, a magnetic body 10 at the upper end of a float 13 which comes into contact with the surface of the lid body 2 compresses a sponge member a little, so as to be brought close to a magnetic sensor 8. Then when the size between the sensor 8 and the magnetic body 10 is measured, the dimension to the sensor 8 from the surface of the lid body 2 becomes H1. When a difference (H1-H0) between a dimension H1 and the prescribed dimension H0 up to the surface of the lid body 2 from the sensor 8 when the lid body 2 is not pressed is within a prescribed value α, a container to be inspected is determined to be a nondefective.  When a container body 1 and the lid body 2 are not brought sufficiently into close contact, the measured dimension H1 becomes large. The difference (H1-H0) becomes larger than the prescribed value α, and airtightness defect is determined.

Patent JP-H10188668-A (JP)
Title: Conductive composition
Inventor: ISHIKAWA MITSUO
IPC: C08K9/02
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To provide stable high conductivity, improve a grounding function, a static electricity removing function, adhesiveness, and abrasive resistance, and reduce the cost by forming a conductive composition with a conductive filler constituted of a blended material of multiple carbon powders having different grain sizes and crystal structures and a composite blended material of silver-coated carbon powder and an aqueous binder. SOLUTION: A conductive filler is preferably constituted of a mixture of needle graphite made from petroleum coke as a raw material and acetylene carbon black and silver-coated graphite. The solid weight ratio between an aqueous resin emulsion used for an aqueous binder and the conductive filler is preferably set to 1:0.15-0.25, particularly 1:0.2. Since the binder is aqueous, the occurrence of a fire is suppressed at the time of coating, and the binder is stabilized via the electrostatic attracting force between its negative charges and the positive charges of the conductive filler. Since the carbon powder is silver-coated, conductivity is improved, the silver consumption quantity is small, and high conductivity is maintained by the composite carbon powder even if it is expanded at the time of a temperature rise.

Filed: 1989-12-27
Abstract: PURPOSE:To increase the purifying rate of HC, CO, and NOx by the Partabeit effect by periodically changing the air-fuel ratio of supply mixture from rich to lean, when an engine is in a low-temperature condition. CONSTITUTION:When it is detected that an engine 1 is in a low-temperature condition by means of a temperature sensor 12, an air-fuel ratio control means 8 controls an injector 3 to periodically change the air-fuel ratio of mixture from rich to lean.
