Title: Dust detection method for wafer
Inventor: MORISHIGE YOSHIO
IPC: G01N21/94
Filed: 1995-04-17
Abstract: PURPOSE: To obtain a filter system detection method for detecting a dust on a wafer by shielding the reflected light from a wiring pattern of an IC chip formed on the wafer. CONSTITUTION: A laser spot SP is projected previously to a dust-free test wafer 1' and a CCD image sensor 61 is inserted between the test wafer 1' and a condenser lens 33 in order to pick up the image of wiring pattern. The image signal is processed at an image processing circuit 62 to produce a pattern data which is stored in a memory 52. When a dust is inspected, a liquid crystal filter is inserted in place of the CCD image sensor 61 and the voltage of each pattern data is applied in order to shield the reflected light from the wiring pattern thus detecting only the light scattered on the dust through a light receiving unit 34.

Abstract: PROBLEM TO BE SOLVED: To provide a timepiece which enables the learning of time being watched from all directions. SOLUTION: A timepiece is so arranged to display time information along an axis marked at 13 points. Thirteen markers divide the axis preferably into 12 parts with the same length and an end part of the axis is marked. Time information is displayed by one or a plurality of indicators moving along the axis at a controlled speed. To display the time information, an indicator surrounding the axis moves along the axis at such a speed that it takes 12 hour to cover the entire length of the axis. To display minuet and second information, two more indicators are added on use.

Title: Error detection system
Inventor: HANABATAKE TOSHIO
IPC: H03M5/14
Filed: 1982-07-01
Abstract: PURPOSE:To prevent an error occurring to some word from exerting influence upon the error detection of a next word, by increasing or decreasing the word digital sum value (WDS) of the next word when the error occurring to the precedent word is detected. CONSTITUTION:Transmitted data is inputted to an nB/mB code converter 1 and a WDS detector 2 to be outputted as (m)-bit data to an output terminal B, and the WDS of the (n)-bit data is found and sent to an adder 3. If RDS(output of flip-flop 4) is caused by a noise to deviates from a value (g) within a specific range + or -N to +N+alpha(h), comparing circuits 5 and 6 output ''1'' and ''0'' respectively and a selector 7 selects +N (information E) and outputs it to the Y terminal of the adder 3.

Title: Integration type analog-to-digital converter
Inventor: KOMATSU KENICHI
IPC: H03M1/58
Filed: 1981-07-24
Abstract: PURPOSE:To obtain a large dynamic range, through the use of a counter with small capacity, by obtaining a digital output proportional to logarithm of an analog input quantity, through discharging the charge in an integrator exponentially. CONSTITUTION:When an analog voltage V is applied to an input terminal A, the voltage V is integrated with a resistor 8 and a capacitor 3 only while an integration time setting switch is closed and a voltage at point B linearly increases. When a switch 1 is opened and a pulse signal is applied to a point D, a discharge switch 4 is closed and the charge in the capacitor 3 starts discharge, while a counter 7 starts counting. Since a discharge voltage generator 11 has a discharge characteristic of exponential function, a voltage waveform at point F changes wavenumber functionally, and then a voltage waveform at a point B changes exponentially. When the voltage at the point B reaches a reference voltage Vref, a voltage at a point C goes to low level, the switch 4 is opened and the counter 7 stops counting and a digital output signal proportional to the logarithm of the voltage V.

IPC: G11B21/21
Filed: 1985-05-28
Abstract: PURPOSE:To obtain a magnetic head support mechanism which stabilizes the floating state of a magnetic head slider by providing a fixture with a load spring for resonance attenuation which extends in the lengthwise direction of a load arm and has a friction projection part which is in contact with the top surface of the arm atop. CONSTITUTION:The load spring 21 for resonance attenuation which is provided with at least one hemispherical friction projection part 22 contacting the maximum amplitude position of resonance mode of the arm surface at the atop and bent in a specific curved shape so as to place a constant load on the friction projection part 22 is provided in the lengthwise direction on the load arm 1. Therefore, if the load arm 1 resonates owing to the oscillation of a driving actuator or external oscillation, disturbance during the rotation of a disk medium, etc., the resonance energy is absorbed by the frictional operation of the friction projection part 22 of the load spring 21 for resonance attenuation which is in contact with the maximum amplitude position of resonance mode on the surface of the load arm 1 with the constant load, thereby attenuating the resonance effectively. Consequently, the floating state of the magnetic slider over the surface of the magnetic disk medium is stabilized.

The length of the tube is extended by a specified length, toward the downstream of laser medium gas flow in the discharge tube from the end portion of the resonator, which specified length is determined by the pumping life tau of medium gas and the average gas flow velocity (upsilon). Hence, in the cavity resonator 1, adequate discharge suitable for laser oscillation is obtained, and the laser medium gas 6 contained in the cavity resonator 1 is utilized for laser oscillation. The laser medium gas contained in the discharge tube extention part 11 outside the cavity resonator is not heated by microwave because said gas exists outside the resonator. Said gas is in the pumping state, and therefore can be effectively used for laser oscillation.
