Abstract: PURPOSE:To make it manufactureble inexpensively besides less n the number of processes by installing a surface layer so as to cover the lower layer and setting the film thickness to more than ten times over the maximum value of a parting line uneven difference. CONSTITUTION:When a roller type contact charger member 5 is formed, there is a method that a thermosetting elastomer is pressed in a die and heated and bridged for forming a lower 5b being installed on an outer circumference of a core bar 5a, but in consideration of easiness or the like at time of separating a product from the die, a parting line 9 is made so as to go in the longitudinal direction in the case of a columnar form, for example, such a method as dividing the into two parts is adopted. A step difference produced in the result is solved by means of covering a surface layer 10. In addition, this surface layer 10 is covered so as to make the film thickness have thickness of more than ten times over the step difference (unevenness)6. With this constitution, its forming can be done so easily.

Title: Noise eliminating circuit
Inventor: YUZAWA HIROSHI
IPC: H03K5/01
Filed: 1987-12-02
Abstract: PURPOSE:To prevent malfunction of the device due to noise invaded in a reception signal by using an output of a frequency-division means frequency-dividing a reference clock to be inputted to generate clocks with different periods so as to sample the input signal invaded with noise and applying logic processing to reproduce the signal into a signal from which the noise is rejected. CONSTITUTION:With an input signal mixed with noise B at level 0 as shown in figure a-1 fed to a shift register(SR) 2, the signal is sampled by a clock CK-1 having a sufficiently smaller period than the period of the input signal in the shift register and fetched sequentially and shifted and outputted in parallel. Since the outputs are ORed by an OR gate 22, the noise of 0 level is rejected. On the other hand, with an input signal mixed with noise B' at level 1 as shown in figure b-1 given, an output shown in figures b-3, 5 is obtained from the SR 21 and a D-FF 23. The signal is sampled by a CK-3 shown in figure a-6 and fetched in an SR 24, shifted and fed to an AND gate 25. Since not all 3-inputs go to 1, the output goes to 0 and the noise of level 1 is eliminated.

IPC: G01N21/956
Filed: 1991-10-24
Abstract: PURPOSE:To obtain a method by which the degree of crystallization of a semiconductor can be evaluated under a non-contact and non destructive state with a small-sized device. CONSTITUTION:By irradiating a single-crystal silicon substrate and thin silicon film to be evaluated with light rays in an ultraviolet region, the wavelength dependency of the ratio K (lambda) of reflected rays of light (reflecting intensity ratio) from both samples is found. Then, after finding the line PL connecting points P1 and P2 indicating the reflecting intensities at a 235-nm and 320-nm wavelengths, an index DELTAK is obtained by finding the difference between a virtual reflecting intensity ratio Ki given by the line PL against a 270-nm wavelength and actual reflecting intensity ratio Kr. Similarly, another index DELTAKa is found on silicon composed only of real amorphous-phase silicon. Therefore, when the indexes DELTAK and DELTAKa are compared with each other, the degree of crystallization of the thin silicon film to be evaluated can be evaluated.

CONSTITUTION: Water is poured into a solvent tank 10 and a fresh liquid tank 16 and the boundary of CFC(chlorofluorocarbon)-113 is covered with a liquid film in order to drop the vapor pressure of the CFC-113. The water is lower in the specific gravity than the CFC-113 and does not mingle therewith and, therefore, the water floats on the CFC-113 and covers the boundary thereof. The vapor pressure may be easily dropped down to <=1/10 that of the case the CFC-113 is not covered with the water simply by pouring of the water. The volume of the water to be put into the tanks suffices if the film thickness of the water is about 20 mm, although the value varies with the sizes of the tanks. The solubility of the water in the CFC-113 is 0.011 wt.% at 25 deg.C or the solubility of the CFC-113 in the water is likewise 0.017 wt.%.  The drying property, recovering property, etc., of the CFC-113 do not substantially change.
