IPC: G01F17/00
Filed: 1984-08-24
Abstract: PURPOSE:To know the amount of one drop of oil of an oil disperser easily and speedily by comparing the diameter of dripped oil with a circular scale on a transparent plate. CONSTITUTION:A gauge plate 2 has four circles 3A, 3B, 5A, and 5B shown as a scale successively in a diameter direction, and the circuits 3A-5B have diameters corresponding to the amounts of oil to be measured, i.e. 0.01 and 0.005cc. Plural drops of oil are dripped on the transparent plate 1 at different places with, for example, the oil disperser. The oil 7 and transparent glass plate 1 are left as they are at room temperature for a time long enough to make the angle of wetting constant and then the gauge plate 2 is applied from below the transparent glass plate 1 to find the circle having the same diamter with the oil 7, reading the amount of oil. When there is not any circle having the same diameter with the oil 7, it indicates that the amount of one drop of the oil dispenser is neither 0.01 nor 0.005cc, and the oil disperser is adjusted to take a measurement again as mentioned above.

Title: Manufacture of semiconductor device
Inventor: OKUBO AKIRA
IPC: H01L29/732
Filed: 1989-07-07
Abstract: PURPOSE:To form a polysilicon film having excellent film quality without decreasing the growing speed of the polysilicon film by directly depositing a polycrystalline silicon film as a lower layer on a single crystal silicon substrate at a temperature lower than a specified temperature, and depositing a polycrystalline silicon film as an upper layer on the polycrystalline silicon film as the lower layer at a temperature higher than the specified temperature continuously. CONSTITUTION:A polysilicon film which is in direct contact with single crystal silicon is grown at a low temperature lower than 580 deg.C. The abnormal growth of the polysilicon film is prevented. Therefore, even if a polysilicon film is grown on said polysilicon film continuously at a high temperature, said polysilicon film is not in direct contact with the single crystal silicon. Therefore, abnormal growth does not occur in said polysilicon film any more. For example, a wafer 13 is put into a chamber 28. Thereafter, the inside of the chamber 28 is kept at the temperature of 560 deg.C. SiH4 gas as a reaction gas ia introduced, and a polysilicon film 17a is deposited. At this time, a part of the polysilicon film 17a is directly in contact with an Si epitaxial layer 15. Since the growing temperature is as low as 560 deg.C, abnormal growth does not occur. Then, N2 gas is introduced. Thereafter, the temperature is increased to 580 deg.C or higher, e.g. to 620 deg.C. Then, the N2 gas is switched to the SiH4 gas, and the growth of the polysilicon film is started.

Filed: 1988-07-18
Abstract: PURPOSE:To eliminate the need for any preamble bit by discriminating a reception signal by an oscillator output with a specific frequency, separating a data at an interval of n-bit from the discriminated pulse signal and extracting in total n-set of data series. CONSTITUTION:An output of a demodulator 10 is given to a sign discriminator 12, which discriminates the sign of the data signal by using the output of a clock oscillator 14 oscillated at a frequency nearly equal to the frequency being n-times the clock frequency of the received data signal as the clock pulse. Pulses are produced from pulse distribution circuits 18-1-18-n at an interval of n-bit from the output pulse train of the clock oscillator 14 respectively and the signal subject to sign discrimination by the sign discriminator 12 is subject to n-branching and its output is given to a memory 24-i and an error detection circuit 22-i. Since it is not required to generate a clock pulse synchronously with the reception signal, the preamble bit required for clock synchronization is eliminated.

Title: Focus control device
Inventor: KIME KENJIROU
IPC: G02B7/28
Filed: 1982-10-07
Abstract: PURPOSE:To obtain a titled device which scarcely causes a variation in characteristic due to surface swing and can execute easily an initial leading-in operation by coupling a fixed side and a moving side by a torsion bar which supports a slide bearing and also has a spring effect. CONSTITUTION:A coil holder 7 and a yoke 9a are connected by a torsion bar 11, and a spring constant term is added to a transfer characteristic. The transfer characteristic becomes a characteristic as shown in the figure, and has a resonance point f0=(K/M)1/2/2pi determined by a spring constant K and a moving part mass M. This spring constant term is a term of displacement and governs a characteristic in low frequency of vibration. Therefore, unless there is a spring term, surface swing dependability by which a term of friction depending greatly on a surface swing governs a characteristic of a low band is scarcely eliminated. Fron a surface swing value (scores of -seveval hundred microns) which is considered to be weight of a general objective lens 4, and a coefficient of friction (about 0.1-0.3) of a sliding part, a value of f0 can be selected within a range of several Hz-scores of Hz. As for the spring constant, it is desirable to make it small from the viewpoint of widening a linearity range and preventing high band resonance.
