Title: Inverter apparatus
Inventor: HIRANO YOSHIO
IPC: G09F9/30
Filed: 1995-07-06
Abstract: PROBLEM TO BE SOLVED: To easily check the rotating diection of a motor by using a 7-segment LED to display the normal/inverse rotating direction of an induction motor in an inverter apparatus. SOLUTION: A display section 1 is formed using four 7-segment LEDs. When a motor is rotating in the inverse direction, numeral 2 of the uppermost digit of the display section 1 blinks with the period of 0.5sec and this numeral 2 extinguishes when the motor is rotating in the inverse direction. In this case, the part of numeral 1 of the 7-segment LED of the most significant digit and the part of 1, 2 of the LED of the other digits is used for display not related to the rotating direction such as output frequency and internal parameters. With display of LED, the rotating direction of motor can easily be detected and it is no longer necessary to add other parts for display of the rotating direction.

Abstract: PURPOSE:To effectively reduce and eliminate a measuring error by subjecting the sensor signal corresponding to the current value of a pump to A/D conversion to calculate an air/fuel ratio signal and setting the input signal range of an A/D converter. CONSTITUTION:An air/fuel ratio sensor 10 is a double-cell type oxygen sensor consisting of a sensor cell 12 and a pump cell 14 and detects the concn. of oxygen in the combustion exhaust gas of an internal combustion engine to measure the air/fuel ratio of the combustion gaseous mixture. The cell 12 outputs the electromotive force Vs corresponding to the concn. of oxygen in the internal space to which the combustion exhaust gas is guided with predetermined diffusion resistance. An IP controller 18 controls the pump current Ip supplied to the cell 14 so that the electromotive force Vs becomes the reference value SV preset by a setting device 16. The output YA of the sensor 10 corresponding to the current Ip is converted to a digital value by an A/D converter 22 and an objective air/fuel ratio signal is calculated from the digital value by an air/fuel ratio operational processing system 24 to be displayed on an external output apparatus 25. At the same time the input signal range FSR of the A/D converter 22 is set by a first concn. correction means 36 and the error due to the irregularity of an oxygen concn. current sensitivity coefficient is corrected.

Title: Manufacture of semiconductor device
Inventor: MORIMOTO NOBORU
IPC: H01L23/522
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To prevent disconnection at a connection hole even if the connection hole deviates from an upper-layer wiring layer by allowing a resist to remain on the surface of the upper-layer wiring layer with a specific thickness when performing ashing elimination of the resist. SOLUTION: In the case of ashing elimination of a resist 17, the resist 17 is allowed to remain on the surface of an upper-layer wiring layer 16 by a specific thickness. Therefore, the surface of the upper-layer wiring layer 16 cannot be exposed to the oxygen plasma directly, thus preventing an oxide layer from being formed on the surface of the upper-layer wiring layer 16. Therefore, when performing a wet treatment by eliminating the resist 17 or the like, an electric charge accumulated on the upper-layer wiring layer 16 is discharged into an amine family organic release liquid without being suppressed by the oxide layer and hence reducing the potential of tungsten 15.  Therefore, even if the upper-layer wiring layer 16 deviates and the tungsten 15 in a connection hole 13 is partially exposed due to miniaturization, the tungsten 15 cannot elute while being accelerated due to the electrochemical reaction, thus preventing disconnection at the connection hole 13 and reducing wiring resistance.

Abstract: PURPOSE: To enable a parasol and a golf club to be held at the same time in one hand by preliminarily forming a fitting part in a grip of the parasol body to locate the grip of the club in the upper part of the parasol. CONSTITUTION: A grip 6a of a club 6 is pushed from the outside into a fitting part 7 formed in a grip 5 so that the grip 6a is positioned in the upper part of an opened umbrella 2 body in a state where a shaft 6b of the club is almost parallel to a shank 3 of the parasol body.

IPC: B23K9/095
Filed: 1980-12-05
Abstract: PURPOSE: To perform adequate welding conforming to the position of the welding to be resumed by selecting the welding condition groups at the start of welding arbitrarily among preset welding condition groups.  
     CONSTITUTION: The welding condition groups set respectively in correspondence to welding regions 1, 2, 3, 4, are stored in a storage device. When a welding stop switch is pushed in the course of welding at condition number 4, the data 4 of a condition number register is transferred to a start condition number register and is stored. Hence, if the welding is resumed by pushing a welding start switch in this state, the data 4 of the start condition number register is transferred to the condition number register and controlling is started by this; therefore, the welding is resumed with the welding condition group at the stopping automatically.  In this way, the arbitrary welding condition groups are selected from the storage device at the start of welding; hence, the welding condition groups at the stopping are selected.
