Title: Motor rotation pulse generation circuit for dc motor and sandwiching detection device using the circuit
Inventor: OKA TOSHIMITSU
IPC: B60J1/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To generate a precise pulse and to detect precise sandwiching with simple constitution by deciding an interruption frequency by clock input, removing the noise of an input signal from a DC motor, shaping a waveform, generating a ripple pulse showing the rotary state of the DC motor and strongly giving a pulse making the frequency of the ripple pulse to be an interruption frequency to a clock. SOLUTION: PLL: 3c outputs the frequency of a ripple pulse inputted to PLL: 3c, which is based on the constant of the relation expression of the interruption frequency of the output of a switched capacitor filter 3a. The output of PLL: 3c is frequency-divided into 50 by a frequency dividing circuit 3d against the input frequency and the frequency dividing circuit 3d outputs the frequency to PLL: 3c. Transmission is controlled so that it is matched with the frequency of the ripple pulse inputted to PLL: 3c and the phase of the output signal of the frequency dividing circuit 3d is controlled. Thus, the interruption frequency linearly changes by the state of pulse output.

IPC: H01L51/40
Filed: 1990-10-17
Abstract: PURPOSE:To form a domain structure of amphiphilic molecules in a monomolecular film by forming a monomolecular film comprising amphiphilic molecule and another amphiphilic molecule having lower crumbling pressure than the first amphiphilic molecule on a hydrophilic liquid surface and compressing the film at higher pressure than the crumbling pressure of the second amphiphilic molecule. CONSTITUTION:An amphiphilic molecule (I) (having both of hydrophilic group and hydrophobia group) which can form by itself a stable monomolecular film is mixed with another amphiphilic molecule (D) having lower crumbling pressure than the amphiphilic molecule (I) and dissolved in a volatile org. solvent such as chloroform. This soln. is developed on a hydrophilic liquid such as pure water to form a monomolecular film. Then a partition board provided on the liquid surface is moved to compress the film at a pressure higher than the crumbling pressure of the amphiphilic molecule (D), and then the pressure is released. By repeating this procedure for proper times, a monomolecular film having a domain structure comprising the molecule (D) separated by molecule (I) can be obtained.

Abstract: PURPOSE:To execute a double speed conversion processing in a digital TV device without causing a disturbance on a screen with regard to a non-standard signal as well by controlling a double speed converting circuit by a timing signal generated by a horizontal period detecting circuit and also delaying an output of the double speed converting circuit in accordance with a variation of a double speed timing signal. CONSTITUTION:A horizontal period detecting circuit 9 detects a period of a horizontal synchronizing signal of an inputted TV signal, varies a double speed timing signal for determining a timing for bringing a present signal and an interpolating signal in a double speed converting circuit 3, to time base compression and multiplexing by a unit of a reference clock in accordance with a periodical variation of the input signal, and executes a control so that a pulse of the double speed timing signal always comes to a horizontal retrace line period. In this case, a double speed signal which is brought to a double speed conversion in the double speed converting circuit 3 is outputted with a time base variation of a clock unit by a periodical variation of the double speed timing signal. As for a variable delay line 5, in accordance with a period variation quantity of the double speed timing signal detected by a variation quantity detecting circuit 11, its delay quantity is varied, and this time base variation portion is compensated. In such a way, the timing of time base compression and multiplexing of a double speed conversion can always be held in a horizontal retrace line period.

Abstract: PURPOSE:To measure the width or the like of a pattern with a high precision even at the time of sticking of dust by discriminating whether a detected pattern width is in an allowable value range or not and supplying the detection signal to an addition unit based on the discrimination result. CONSTITUTION:A scan signal is outputted from a deflector control unit 4 to a deflector 3 by the command from a computer 5, and the scan position of an electron beam EB is moved many times across a pattern P on a sample 2 to perform linear scanning. Reflected electrons from the sample 2 are detected by a detector 6 and are not only stored in a buffer memory 9 but also supplied to a pattern width detecting unit 10.

IPC: G06F12/16
Filed: 1998-10-01
Abstract: PROBLEM TO BE SOLVED: To enhance the transfer rate of a relief result and to shorten the test time in a memory testing apparatus which tests a plurality of memories at one time, by which their test result is stored in a defect analysis memory and which analyzes whether the memories can be relieved or not. SOLUTION: Sorage devices 119F are installed at relief analyzers 119B. Data transfer passages 119G are installed across computing units 119C and the relief analyzers 119B and a main controller 111. Relief results which are computed by the computing units 119C so as to be found are stored temporarily in the storage devices which are installed at the relief analyzers 119B. The stored relief results are read out, directly through the data transfer passages which are installed especially. As a result, the relief results can be sent to the main controller 111 in a short time. Thereby, since the relief results are sent to the main controller 111 in a short time, the time required for advancing to a next test becomes short, and an advantage that the time required for a test can be shortened is obtained.
