Abstract: PURPOSE:To obtain a normal freeze picture independently of the movement of a picture by providing a means for storing the storage of a field memory for interpolation between fields and outputting continuously the information in the field memory to prevent resolution from deteriorating. CONSTITUTION:When the 3rd switch circuit 31 is connected, an output of the 3rd field memory 34 is fed back to the input of the field memory 24 and the information in the field memory 24 is held.

Thus, the same information as the existing field information and the information before one field is led to the interpolation filter 25. An inter-field interpolation cut off signal deciding whether or not the inter-field interpolation is applied in the interpolation filter 25 is used to stop the inter-field interpolation or apply the interpolation in field and the stop the inter-filed interpolation or apply the interpolation in field and the said signal is outputted repetitively.

Abstract: PURPOSE:To detect only abnormal blood flow noise, by mounting a means judging that respiratory sound data and the vibration data of a throat are respectively predetermined values or less, a means of storing the blood flow sound waveform data of one heartbeat and a means of analyzing the blood flow sound waveform data on the basis of a judge signal. CONSTITUTION:Blood flow sound having a plurality of analogue waveforms is detected from the blood flow noise detection means 6 mounted to the head of an examinee 7 and amplified by a blood flow noise amplifying means 9 to be inputted to an A/D converter 12. At the same time, the respiratory sound and throat vabration sound to the blood flow sound are also inputted to a noise mixing judge means 17 from a respiratory sound detection means 16 and a throat vibration sound detection means 18. Only when the inputted respiratory sound and throat vibration sound are sufficiently smaller than preset threshold values, the judge means 17 sends a data effective signal to a buffer memory 14. Since the digital data (blood flow sound waveform data) of one heartbeat is stored in the memory 14, said data is sent to a waveform data analyzing means 15 only when effective to analyze the blood flow sound.

Title: Compound semiconductor electrode
Inventor: YASUDA NOBUROU
IPC: H01L29/43
Filed: 1982-11-01
Abstract: PURPOSE:To obtain an electrode with excellent property of bonding and ohmic contact, by providing an electrode constituted of an Au alloy layer, a Ti layer and an Au layer or an Al layer or the alloy layer on a P type compound semiconductor layer. CONSTITUTION:An N type GaP layer 21b and a P type GaP layer 22 are formed on an N type GaP substrate 21a resulting in the formation of a P-N junction 23. The Au-Be alloy layer 24, the Ti layer 25 and the Au layer 26 are formed on the layer 22, then three layers are applied to patterning, and accordingly the ohmic electrode of the layer 22 is obtained. Thus, by constituting an electrode, the Ti layer 25 becomes a stopper layer of Ga, P or Be, and therefore a good ohmic is obtained. Since an alloying is performed, the migration of atoms of Ga, P or Be is prevented during a heat treatment, and accordingly those atoms do not reach the surface of the Au layer 26. Thereby, a bonding can be easily performed.

Title: Group ii-vi semiconductor laser and its formation
Inventor: MATSUOKA TAKASHI
IPC: H01S5/24
Filed: 1993-08-02
Abstract: PURPOSE:To enable current constriction/transverse mode control by providing a specified slant groove to a semiconductor, by arranging laser structure comprised of a lower clad, an active layer and an upper clad of a group II-VI semiconductor and by arranging a lower clad or an upper clad in a groove surface. CONSTITUTION:Semiconductor laser structure having II-VI compound semiconductor in an active layer 104 is arranged on a semiconductor substrate 101 with a reverse trapezoid-shaped groove to attain both transverse mode control and current constriction at the same time. Since a group II-VI semiconductor formed on a (111) surface which is a slant of a groove becomes high resistance, current constriction can be attained. Furthermore, since a bottom surface is parallel to a substrate surface and there are a carrier containment layer 103 and a light confinement layer 102 whose refraction factor is lower than that of the active layer 104 formed in a groove bottom part whose side surface has a (111) surface or a slant slightly tilting from the (111) surface, transverse light confinement can be carried out.

Abstract: PURPOSE:To obtain a recording device which can erase at the same inclination as that of recording locus and gives the same effect as a flying erasing head does with a simple structure, by installing an erasing head which erases obliquely recorded loci to the surface of a guide body containing a rotary recording head. CONSTITUTION:When a tape 1 is fed in the direction shown by an arrow A and a central drum 7 is rotated in the direction shown by the other arrow B, each erasing head 11 starts the erasing at the same inclination as the direction of length of an obliquely recorded locus 15 using a video head 9, because each erasing head 11 is arranged on a plane which is parallel to the rotating plane of the video head 9. By overlapping the gap of each erasing head 11 by the width (d) of erased loci 13 as shown by broken lines 14, unerased parts can be eliminated.

Title: Solid-state image sensing element
Inventor: NAKA SHUNICHI
IPC: H04N5/335
Filed: 1990-07-17
Abstract: PURPOSE:To decrease smear defects by forming a filling layer having the refractive index which is larger than the refractive index of an insulating layer directly or through an intermediate layer having the approximately same refractive index as the index of the insulating layer on the insulating layer. CONSTITUTION:A CCD solid-state image sensing element has the constitution wherein a conventional part is covered with an intermediate layer 8 and a filling layer 9 is provided on the intermediate layer 8. An insulating layer 6 is an SiO2 film, BPSG or the like, and its refractive index is 1.4-1.5. The intermediate layer 8 is formed of an acryl-based resin having the similar refractive index as that of the insulating layer 6. The filling layer 9 is formed of a material having the refractive index of 1.6-1.7 or more. The filling layer 9 is formed so as to fill the concave recessed part at the upper part of a photodiode 2. Since the refractive index of the layer 9 is larger than those of the intermediate film 8 and the insulating film 6, the action of a convex lens is performed at the upper part of the photodiode 2. Therefore, oblique incident light is refracted to the side of the photodiode 2. As a result, the amount of light reaching the deeper part than the charge transfer region in the substrate becomes less, and the smear defects can be decreased.
