Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To enhance carrier mobility and lessen reverse short channel effects, by oxidizing a part of a semiconductor body in oxidation sequence, consisting of at least one time of dry oxidation step and one time of wet oxidation step. SOLUTION: A transistor, which has a gate dielectric 16 made in the oxidation sequence where wet oxidation follows dry oxidation and dry oxidation follows this, is made at the semiconductor body 10. A drain region 12 and a source region 14 are separated from each other by a part of the semiconductor body 10. The main body 10 is one conductivity type, for example, a p-type, and the drain region 12 and the source region 14 are opposite conductivity type, for example, an n-type. The region where a source and a drain are made is demarcated by various known mask techniques. A gate dielectric 16 is made on the region between the source region and the drain region 12.

IPC: C08G73/00
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To provide an electrically conductive resin composition which cures at a low temperature. SOLUTION: An electrically conductive resin composition contains a water-soluble electrically conductive polymer (a), which is doped with an external dopant, and a modified hydrophilic group-containing polyester resin (b) which is modified by a polymer of an unsaturated bond-containing compound. The proportion of the polymer of the unsaturated bond-containing compound in the hydrophilic group-containing polyester resin modified product (b) is from 0.1 to 500 wt.%. The water-soluble electrically conductive polymer (a), which is doped with an external dopant, is at a state wherein the electrical conductance is 10-6 S/cm or larger and the water solubility (25 deg.C) is 0.5 wt.% or larger. Since this electrically conductive resin composition cures at a low temperature, it may be used as base materials softened at a low temperature.

Title: Fixed lead frame and its manufacture
Inventor: UEDA JUN
IPC: H01L23/14
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To relieve thermal stress applied to a bonding surface between a lead frame and bumps where thermal stress is caused by difference of thermal expansion coefficients, by burying resin having thermal expansion coefficient approximate to that of a semiconductor chip in the peripheral parts of protrusions of a lead frame having the protrusions, and flattening the surface. SOLUTION: Leads 3b are formed by cutting specified parts of a lead frame for semiconductor formed of copper alloy, iron alloy, etc., and have protrusions 3a at the tip parts. In chip mounting areas of the leads 3b, recessed parts around the protrusions 3a and aperture parts are filled with resin 4 up to the height of the protrusions 3a, and the surfaces of the leads are flattened. A structure where only the surfaces of the protrusions 3a are exposed is obtained. Since stress applied to a bonding surface between the lead frame and the bumps can be reduced when both a semiconductor chip 1 and the resin 4 expand and contract in almost the same degree in a heating process or a cooling process, resin having thermal expansion coefficient approximate to that of the semiconductor chip 1 is suitable for resin used in the above case.

Title: Exhaust gas sensor and exhaust gas sensor system using it
Inventor: INOUE TAKAHARU
IPC: G01N27/419
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To provide an exhaust gas sensor for freely measuring a plurality of exhaust gas component concentrations by one sensor and hence having many general purposes. SOLUTION: In the exhaust gas sensor 1, an oxygen concentration in an exhaust gas introduced into a first treating chamber 9 is reduced in a range that a decomposing reaction of an oxygen-containing gas component does not substantially occur, and then introduced into a second treating chamber 10. The gas pumped at the oxygen by a second pumping element 5 for operating by a constant voltage so that the oxygen- containing gas component is decomposed. In this case, the more a content of the oxygen-containing gas component in the gas is, the greater the oxygen content generated by the decomposition is increased. Since a current value of a second pump element 6 is increased, a concentration of the oxygen-containing gas component can be known by reading the current value.  The oxygen-containing gas component has a different decomposing oxygen partial pressure level according to its type, and hence the oxygen- containing gas component corresponding to the operating voltage can be selectively detected by altering the voltage of the element 6 in response to the type of the oxygen- containing gas component to be detected.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of address bus lines and to enhance degree of integration by buffering a first address signal, delaying the buffered address signal for a prescribed time, buffering the buffered address signal and the delayed address signal and generating a second address signal. SOLUTION: When a read-out command is outputted, and an external address buffer 41 receives the address signal, a read-out control signal CASATV6-RD becomes high, and an NMOS transistor G18 is turned on. A write-in control signal CASATV6-WT and a burst control signal ICASATV6 become low, and the NMOS transistors G50, G19 are turned off. When a delay element 43 causes the buffered address signal to delay by two clocks by through a write-in command, the write-in control signal CASATV6-WT becomes high, and the NMOS transistor G50 is turned on.

Title: Ventilator for inverter air conditioner
Inventor: MAEDA SHIRO
IPC: B01D46/00
Filed: 1997-12-27
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous operation at the inverter control section and corrosion of a printed board due to intrusion of sea salt particles by providing means for blocking counter flow of sea salt particles from an outdoor fan at the suction port. SOLUTION: During operation of an air conditioner, the air from an outdoor fan 3 flows through an air supplying opening 4 into the inverter side control section 1 and passes through a filter 6 before being discharged from an exhaust opening 5. The opening 4 has a minimum necessary area for cooling the inverter control section 1 in order to avoid intrusion of detrimental substance from the outside as much as possible and since the distance from the opening 4 to the electric parts on a printed board 1a is long, intrusion of sea salt particles can be neglected. When the air conditioner is stopped, detrimental substances, e.g. sea salt particles, contained in the outer wind being supplied from the fan 3 arrives at the opening 5 but they are blocked by the filter 6 and prevented from intruding into the control section 1.  Consequently, erroneous operation at the inverter control section and corrosion of the printed board can be prevented.

IPC: G01N27/409
Filed: 1998-12-28
Abstract: PROBLEM TO BE SOLVED: To provide an oxygen sensor in which the position of a ceramic heater in the inner space of a detection element is hardly shifted. SOLUTION: A recess part 17a, engageable with a heater gripper 9a, is formed on the circumferential face of a ceramic heater 17 for heating and activating a detection element of an oxygen sensor.
