Title: Air/fuel ratio sensor
Inventor: MURASE TAKAO
IPC: G01N27/419
Filed: 1989-11-28
Abstract: PURPOSE:To reduce the temp. dependence of the measuring accuracy of a sensor by controlling the electrical leak quantity between an electrochemical oxygen pump cell and an electrochemical oxygen sensor cell. CONSTITUTION:Since the potential of the outside electrode 18 of an oxygen pump cell 12 becomes higher than the reference potential set to the inside electrode 20 thereof when the air/fuel ratio of combustion gas is within a lean region, a leakage current flows to the measuring electrode 28 of an oxygen sensor cell 14 from the electrode 18 and the electrode 28 is held at a potential higher than the reference potential by a predetermined level by an electric resistor 56. The ratio of the quantity of the leakage current and that of a pump. current can be controlled by controlling the resistance value of the resistor 56. When the air/fuel ratio is within a rich region, the electrode 18 becomes negative but, in this case, the potential of the electrode 28 is also held so as to be lower than that of the resistor 56 by predetermined level in the same way and the quantity of the leakage current is controlled. By this constitution, a problem such as the lowering of the measuring accuracy of a sensor or the change of characteristics thereof with the elapse of time can be reduced ore eliminated.

Title: Semiconductor integrated circuit and its manufacture
Inventor: TANAKA HIROSHI
IPC: H01L21/82
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To enable cells of different power supply voltages to be optionally arranged in the same cell row so as to effectively use cell rows by a method wherein the well of a cell row is divided into sub-wells, and the sub-wells are electrically isolated from each other. SOLUTION: Inner cell rows 12 each composed of a row of cells arranged in a line are formed in parallel with each other in a center region on a chip 10. In one out of the cell rows 12, a certain conductivity-type well included in an inner cell row forming region is divided into several sections, and the sections are electrically isolated from each other. In this case, cells 21 which operate on a low power supply voltage and cells 22 which operate on a high power supply voltage are alternately formed in the direction of a cell row. Therefore, power supply wirings of two kinds and a ground wiring are selectively connected to the cells, whereby cells of two kinds which operate on different power supply voltages can be mixedly arranged in the direction of an inner cell row. By this setup, cell rows can be effectively utilized.

Title: Production of superconducting material
Inventor: YAMADA MANABU
IPC: C01G1/00
Filed: 1987-12-04
Abstract: PURPOSE:To obtain a dense superconducting material having stable characteristics and consisting of a single phase by mixing a mixed soln. contg. a rare earth element, Ba, and Cu with a precipitant consisting of an amine which forms no complex ion with Cu ion, in a solvent, and calcining a coprecipitate after drying, precalcination, and molding. CONSTITUTION:A mixed soln. contg. at least a king of rare earth element (e.g., Y), Ba, and Cu is prepd. The mixed soln. is mixed with a precipitant (e.g., diethylamine) consisting of an amine which does not form a complex ion with Cu ion while adding the mixture to a solvent (e.g., ethanol), to form thus coprecipitate. After drying the coprecipitate, oxide powder is produced by precalcining the dried coprecipitate at 700-950 deg.C. The oxide powder is molded and then calcined at 900-1000 deg.C to obtain thus a superconducting material. By this method, each raw material can be mixed uniformly, so a dense superconducting material consisting of a single phase is produced.

Title: Automatic nail driver
Inventor: TERAYAMA TSUNEHISA
IPC: B25C1/04
Filed: 1987-12-04
Abstract: PURPOSE: To prevent that a nail head is detached from the nail head pressing part of a nail feed apparatus by the counteraction of a blow by providing a gap between the nail feed apparatus and the guide truck of a magazine and inclining the nail feed apparatus to allow the same to follow the loading angle of a connected nail. CONSTITUTION: The guide surface 8 of a nail feed apparatus is loosely fitted to the guide track 7 of a magazine and the nail feed apparatus is pushed toward an ejection port by a pivotally supported spring 6 to be pressed so as to follow the loading angle of a connected nail and the rear part thereof is inclined upwardly to generate an in clined nail feed angle 14. The collision part 11 of the nail feed apparatus collides with the magazine attaching surface 10 on the side of the ejection port 12 in such a state that the final nail of the connected nail is driven in and, since rotatory power generating a nail holding inclined angle 13 acts by the pulling force of the spring 6, the peeping quantity of a nail pushing part 12 into the ejection port becomes large.  Since a nail head pressing part 15 retreats at this time, the protruding quantity of the nail head pressing part 15 can increase by this retreat quantity and a nail head is not detached by reaction force at a time of driving-in.

Title: Outsole for footwear
Inventor: UMEZAWA IKUKO
IPC: A43B13/22
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To obtain a high antislip property and high strength on a wet foothold by compounding a silylating agent which bonds to silica but does not bond to a polymer and a silane coupling agent which bonds to both. SOLUTION: The silylating agent which has bondability to the silica but does not have bondability to the polymer is compounded with a rubber compsn., by which the water repellency of the silylating agent acts effectively on the compd. and an water repellent property is imparted to the compsn. The silane coupling agent having the bondability to both of the silica and the polymer together with the silica is compounded with the rubber compsn., by which the silica and polymer i.e., fillers for reinforcement, are connected via the silane coupling agent and the strength of the rubber compsn. is effectively enhanced. When a user moves on the wet foothold, the outsoles enhanced in the strength come into contact with an adequate contact pressure without the significant deformation in the state of loading the outside with the human body weight.  Simultaneously the outsoles allow the water of the foothold to escape outside and is capable of creating large friction resistance with the foothold. The extremely good antislip property is achieved by the friction resistance coupled with the water repellent property by the silylating agent.
