Title: Substrate treatment
Inventor: IZEKI IZURU
IPC: H01L21/31
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To apply a treatment solution uniformly by controlling a driving means so as to slow the moving speed of a treatment solution supplying means, as it is moved from the center side of a board toward the end brim side. SOLUTION: Operating a motor 2 at a constant speed, an application head 10 is moved toward the end brim side of a substrate W along its radial direction, and is stopped when it has moved up to a position exceeding the end brim part of the substrate W. At this point, the moving speed of the application head 10 is not constant, and it is made slower according to an application site being along the radial direction of the substrate W. By making the moving speed of the application head 10 slower in this way, it becomes possible to make the quantity of a photo resist solution to be supplied approximately constant, regardless of the site of application. Besides, it becomes possible to make it difficult for the spiral locus of the photoresist solution to produce intervals, and to suppress unevenness.

IPC: G01V3/08
Filed: 1981-10-01
Abstract: PURPOSE:To make the detector high-sensitivity by installing a detecting capacitor at adetection point and connecting this capacitor to a separately provided detecting part main body through a coaxial cable and connecting the reactor of a prescribed inductance value in parallel. CONSTITUTION:Only a detecting capacitor C2 as an element constituting a detecting part 10 is installed at a moving object detection point and is connected to prescribed points A and B of the detecting part through a coaxial cable l1. A reactor L is connected between points A and B; and when the electrostatic capacity C2 of the detecting capacitor C2 and the capacity of the coaxial cable l1 are denoted as C2 and CC respectively, the value of the inductance L is so selected that expression is true. Thus, the apparent electrostatic capacity at the view from points A and B of the detecting part 10 corresponds to the capacity variation due to approach of a human body approximately, and the influence of the stray capacity of the coaxial cable l1 is reduced considerably, and a high-sensitive detection is possible. Consequently, the sensitivity is enhanced.

Filed: 1984-07-30
Abstract: PURPOSE:To perform contactless polishing of wafer uniformly by magnetically supporting a reference plate adhered with wafer while controlling the gap between the wafer and the polishing machine to be constant at any time. CONSTITUTION:Upon power supply from float control section 5 to an electromagnet 17, the outercircumferential sections of first and second discs 15, 16 are magnetized in opposite polarity against the magnet of said magnet 17. Since the facing sections of the discs 15, 16 will have same polarities, repelling force is produced to float the disc 15, supporting shaft 13 and reference plate 2 adhered with Si wafer thus to produce a gap between the wafer 12 and the polishing cloth 11. Here, a signal indicating the distance between a contactless sensor 19 and the disc 15 is provided from the sensor 19 to the float control section 5 thus to maintain the gap between the wafer 12 and the polishing cloth 11 constant. Under this state, polishing board 8 is rotated to flow the polishing liquid on the upper face of the polishing board 8 toward the outercircumferential section through centrifugal force thus to work the wafer 12 uniformly.

Filed: 1988-06-24
Abstract: PURPOSE:To reduce the number of manhour of software and to speed up processing by generating a vector interruption signal by a coincidence signal based upon hardware comparing operation between data values inputted from plural ports and a previously set data value. CONSTITUTION:A sampling circuit 1 samples data inputted from the ports for a fixed time, an input data storing register 2 is an 8-bit register to which sampled data are transferred and a data setting register 3 is a programmable 8-bit register. A comparator 4 compares the contents of the register 2 with that of the register 3, and when both the data coincide with each other, outputs a coincidence signal 5 and generates a vector interruption request signal 6. Consequently, the branch of program processing based upon the input data values from the ports can be executed without using software, so that the man hour of the software can be reduced and rapid processing can be attained.

Title: Audio digital signal processing unit
Inventor: KITAGAWA SHIGERU
IPC: H03H17/02
Filed: 1990-06-18
Abstract: PURPOSE:To eliminate click noise at the time of updating the characteristic of 2nd and succeeding stages of a digital signal processing section by processing a first stage of the digital signal processing section through the provision of a high pass filter whose cut-off frequency is sufficiently low so as not to give adverse effect on the signal processing of the post stages. CONSTITUTION:An analog signal fed to an input terminal is outputted to a DSP 2 while being superimposed on a DC offset voltage, and since 1st stage digital signal processing of the DSP 2 acts like an HPF processing stage whose cut-off frequency is nearly 3Hz, the frequency component of 3Hz or below is not inputted to a bass processing stage and a treble processing stage being 2nd and succeeding digital signal processing sections. Thus, since the DC component included in an A/D conversion data is eliminated at the first stage of the signal processing, DC gain is independent of the post-stage processing.
