Title: Semiconductor wafer washing method
Inventor: AKAISHI YOSHIO
IPC: C11D7/06
Filed: 1995-06-21
Abstract: PURPOSE: To wash off metal ions deposited to a Si oxide film of a semiconductor wafer to thereby prevent the metal ions from being readsorbed to the wafer after washing by using a washing liq. contg. a chelating agent and neutral ligand added to a water soln. contg. ammonium hydroxide and hydrogen peroxide. CONSTITUTION: To wash before oxidation, a semiconductor wafer to be washed is set in a washer and washing of the wafer is started. A washing liq. in a washing vessel uses a water soln. of ammonium hydroxide and hydrogen peroxide plus a chelating agent and neutral ligand added thereto. Thereby metal ions such as Mg ions can be surely removed and readsorption can be avoided to prevent the reduction of the reliability of an oxide film and the occurrence of defects such as increase of the leakage due to the degradation of the junction withstanding voltage and the metal ions deposited to the Si oxide film can be washed off.

Title: Pid controller
Inventor: NAGAO TOSHIAKI
IPC: G05B13/00
Filed: 1985-07-12
Abstract: PURPOSE:To shorten the tuning time by performing the turning actions at a time for plural control loops in a tuning mode of the PID constant of a controlled system. CONSTITUTION:Plural loops receive the operations based on the control inputs obtained from plural detecting points and the tuning actions are carried out at a time for these loops. Thus the PID constants of each loop are calculated at a time. Then the loops with which the tuning actions is through performs the control based on the obtained PID constants before the PID constants of all loops are calculated. In such a way, the optimum tuning is possible with each PID constant when the controlled system is controlled at operating points 5a-5c having the mutual interference.

Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To improve abrasion resistance and steering stability by making the contour line of a tread surface in a tire meridian cross section into a tread curve in which a radius of curvature is continuously reduced from a tire equatorial point toward a tread edge and the center of the radius of curvature forms into the orbit of an ellipse. SOLUTION: In a contour line L on a tread surface in no-load tire meridian cross section which is rim-assembled and is filled with using internal pressure in this tire, a radius R of curvature is continuously reduced from a tire equatorial point Pc to a tread edge (e). The contour line is constituted of a tread curve Tc in which the center of the radius R of curvature forms into an orbit D of an ellipse.

Title: Optical information eraser
Inventor: TAKEGAWA HIROZO
IPC: G11B7/00
Filed: 1986-07-02
Abstract: PURPOSE:To surely completely erase information with less thermal damage by a low power, by approximately simultaneously projecting a circular spot light having a lower power density and an elliptic spot light having a higher power density. CONSTITUTION:A circular spot a1 and an elliptic spot b1 are approximately simultaneously projected to the same recording track. A beam diameter b1x in the recording track direction of the elliptic spot is set to a relatively large value for the purpose of gradually cooling a fused recording material film, and the beam diameter b1y in the direction orthogonal to the recording track is set to a value larger than the track width. The peripheral edge part of the elliptic spot b1 having a relatively low power density covers a spot 2 to gradually raise the temperature of the spot 2, and the recording material film is fused with an about track width by the center part of the elliptic spot b1 having a higher power density and the circular spot a1 having a lower power density and is gradually cooled by the elliptic spot b1 having a relatively low power density and is crystallized to erase information. Thus, an eraser is obtained where the required laser power is low and thermal damage is small and information is not left unerased.

Abstract: PURPOSE:To enable accurate detection of a bearing of a vehicle, by determining the bearing of the vehicle based on the preceding value of output data of an earth magnetism sensor when output data of the earth magnetism sensor is not within an allowable range continuously for a specified time. CONSTITUTION:When output data of an earth magnetism sensor 1 is not within an allowable range set based on rule, the count N of an allowable-range-of-error counter is incremented by one and subsequently, output data currently taken in from the sensor 1 are regarded as errors until the value N reaches a maximum Nmax to determine the bearing of a vehicle by utilizing the bearing obtained based on the preceding value of output data of the sensor 1. When the value N reaches the maximum Nmax, the count E of a center-value deviation counter is incremented by one and subsequently, a timer is set for a certain time until the value E reaches a maximum Emax to calculate the bearing by taking in output data of the sensor 1 until the set time of the timer expires. Thus, proper action can be taken even when irregular data are taken in owing to a sudden turning of a steering wheel or the like.

Abstract: PURPOSE:To surely avoid the collision of data by sending a pattern specific to a node to a transmission line from a transmission request node and starting the data transmission when the specific pattern of its own node is detected on the transmission line. CONSTITUTION:When a carrier detection section 3 of a transmission request node detects the absence of a carrier on the transmission line 2, a pattern specific to the node is sent from a specific pattern transmission section 4 to the transmission line 2 and a specific pattern detection section 5 detects whether or not the pattern specific to its own node. If collision of a specific patterns is detected, the transmission is stopped, the carrier is detected again and the specific pattern is sent in case of the absence of the carrier. Furthermore, after the transmission of the specific pattern, when the specific pattern detection section 5 detects the specific pattern of its own node, it is discriminated as the absence of occurrence of collision, and a data is sent to the transmission line 2 from a data transmission processing section 6. Thus, the data collision is surely avoided.
