IPC: H01L27/00
Filed: 1987-03-17
Abstract: PURPOSE:To reduce soft error by parasitic capacitance and alpha-ray by forming a recessed element forming region through the etching of insulating film, making flat the surface after filling the element forming region with an epitaxial layer and making equal the level difference to thickness of source drain. CONSTITUTION:After forming SiO2 film 2 on a silicon substrate 1, the SiO2 film is etched to form a rectangular recessed element forming region 10 and a groove 3 is provided to expose the surface of silicon substrate 1. Next, Si is grown on the insulating film from the silicon surface of groove and Si is deposited until the stepped portion of SiO2 film 2 is covered. Next, the epitaxial layer 4 of the part which is thicker than the SiO2 is etched for the flattening. Next, a gate oxide film 5 is formed on the surface of epitaxial layer 4, a polycrystalline silicon film including phosphorus of high concentration is deposited and a gate electrode 6 is formed. Thereafter, a source drain region 7 is formed by implanting arsenic. Then, after forming an inter-layer insulating film 8, a contact hole is formed and then an aluminum wiring 9 is formed. Thereby, elements can be isolated easily and soft error by parasitic capacitance and-ray can be reduced.

IPC: H04N1/04
Filed: 1979-05-24
Abstract: PURPOSE:To eliminate the need for adjustment in terms of aging deterioration and that for every fluorescent lamp, by providing strips of shielding members between the fluorescent lamp and an original surface lenghtwise along the lamp. CONSTITUTION:Eight shielding members 6a-6d symmetric on surface H perpendicular to axial line X and penetrating axial center C of fluorescent lamp 1 are arranged. The arrangement pitch is smaller at the center part and larger at both ends. Center members 6a are arranged in parallel to original face 4 and members 6d at both ends are arranged spreading out and slanting so that the distances from members 6a increase toward face 4. Intermediate members 6b and 6c are slanted more than members 6a and less than 6d respectively. Then, angles of members 6b-6d are set with thetad>thetac>thetab and their values are adequately set; and the width of an opening between adjacent members is set with W0<W1<W2<W3 and light beam penetrating them increses the intensity of illumination on face 4 at both the ends, so that the shade of an image on photo detection surface 8a of photo detecting element 8 at the circumference of lens 7 can be corrected. Thus, no light at both the ends is used in this mechanism to eliminate the need for adjustment in terms of dispersion, etc., in lamp light.

Title: Detection for corroded part of pipeline
Inventor: HOSOE TOSHIAKI
IPC: G01N29/04
Filed: 1985-03-29
Abstract: PURPOSE:To enable highly accurate detection of a corroded part of a pipeline regardless of a deformation out of roundness of the pipeline body and the existence of vibration with the running of a pig, by using a spot focusing type probe as such. CONSTITUTION:Empirically, for example, in a pipeline of a pipe body 1 with the nominal diameter of 1,200A, the flatness (f) of the pipe body 1 is mostly below + or -30mm while the eccentricity (d) of a pig 3 is normally below + or -10mm. When the oblatness f=30mm, the incident angle theta is about 1 deg. at the point Q when the change in the incident angle due to the eccentricity of the pig 3 is large. Hence, the incident angle is about 1 deg. at a point even if the point P and the point Q coincide. Thus, the use of a spot focusing type probe enables highly accurate detection of a corroded part of a pipline of the pipe body of which is deformed by oblatness =+ or -30mm under the vibration in which the pig 3 is deformed by oblatness d=+ or -10mm.

Abstract: PURPOSE:To attain a work feeder with a buffer function which provides a large amount of work storage and carries and feeds even a work of unstable center of gravity with high stability. CONSTITUTION:This work feeder is provided with an outside guide 24 for works fixedly-arranged along the outsides of the first conveyer 2 and the second conveyer 2, and an inside guide 24'' for works which guides a work W by expanding or contracting with the movement of a semi-circular guide for works, ranging from a semi-circular guide 24' for works to the receiving part 3' of the discharge port 1' of a single discharging machine 1 or the receiving port 3' of a one-row discharging machine 3 along the insides of the first conveyer and the second conveyer 1'. Since the works do not incline to the outside of the conveyer, and support each other and do not incline in the carrying direction of the conveyer, even works of unstable center of gravity are delivered with high stability. Besides, the semi-circular guide 24' for works, a rotating plate 21 and a body 6 are moved continuously, so that it is possible to increase the storage amount (buffer function) of the works W within one cycle operation period of the one- row discharging machine 3.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To improve compatibility by changing and controlling frequency characteristics and linearity accuracy in accordance with the various modes of tracking in the tracking servo signal processing of an optical disk device. SOLUTION: Input parts 20A and 20B logarithmically compress input current signals IsA and IsB, convert these signals to voltage signals VsA and VsB and output them. An AGC arithmetic part 28 receives the voltage signals VsA and VsB and outputs an AGC output. In this case, a variable constant current source 27 changes the values of variable constant currents IdA and IdB corresponding to a control signal CL and according to this change, the values of constant currents IbA and IbB are changed. In the modes of on-track and high- speed search, the values of the constant currents IbA and IbB are reduced, the frequency bands of the input parts 20A and 20B are narrowed and in place of that, the linearity accuracy of the AGC output is improved. At the time of envelope servo, the values of the constant currents IbA and IbB are increased, the frequency bands are widened and the linearity accuracy is lowered.

CONSTITUTION:A digital data for L channel is fetched to a counter 101 at first in the timing of a shift clock 103 from a control circuit 102 and set to the counter. The control circuit 102 starts counting-down by a load signal 104 and closes a current source switch 105. In this case, the L/R changeover switch 106 or the like is thrown respectively to a prescribed circuit and a current from a constant current source 110 flows to a capacitor 112 of the integration circuit 111, to cause the capacitor to be charged. While a capacitor 118 is charged succeedingly, the electric charge stored in the capacitor 112 is discharged through the L/R changeover switch 106. When the count-down at the counter 101 is finished, a carry signal 113 is outputted and a current source switch 105 is opened by the signal. Then the control circuit 102 outputs an R-channel deglitch signal 119.

Abstract: PURPOSE:To prevent separation from occurring an reduce parasitic capacitances of bit lines by inserting a buffer insulation film E of SiO2 between the bit lines whose surface is made of WSi2 and an etching protection film of Si3N4. CONSTITUTION:A buffer insulation film 22 made of SiO2 and an etching protection film 13 made of Si3N4 are formed by applying the CVD method.

Also, SiO2 and WSi2 are wettable with each other and can be well adhered to each other and then adhesion strength between SiO2 and Si3N4 is far greater than that between WSi2 and Si3N4. Also, dielectric constant of SiO2 is approximately 4, which is smaller as compared with that of approximately 7 of Si3N4.

Abstract: PURPOSE:To offset a synchronizing noise and to prevent a noise from appearing in an image when the synchronizing noise is mixed by giving a proper delay to the synchronizing noise for each false signal even in the direction just under an oscillator. CONSTITUTION:When the synchronizing noise is mixed in a signal line, the synchronizing noises are mixed in signals S1, S2, S3,...Sn corresponding to a beam in the just-under direction of an ultrasonic oscillator in the same phase, and as signals SD1, SD2, SD3,...SDm of the signal lines to be connected to a delay line 10, the signals different in phases delayed in a prescribed quantity, respectively, are outputted. Consequently, when the signals S1, S2, S3,...Sn and the signals SD1, SD2, SD3,...SDm of the dummy signal lines are synthesized by an adding circuit 6, the synchronizing noise is offset, and an output signal SS, in which the synchronizing noise is not mixed, is obtained from the adding circuit 6. Namely, since the addition is executed in the different phases even when the synchronizing noise is mixed, the noise is offset even in the just-under direction vicinity of the oscillator, and the noise cannot appear in the image as the noise.
