Abstract: PROBLEM TO BE SOLVED: To reduce the size of various patterns or of various pattern intervals for semiconductor integrated circuit device. SOLUTION: An inter-layer insulation film 3d for covering a plurality of wirings 2a is formed on an inter-layer insulation film 1 by the bias sputtering method. A projecting part 3d is left directly the wirings 2a in the inter-layer insulation film 3d. Then a covering insulation film 4 made of silicon nitride is formed on the inter-layer insulation film 3d. Further, after an inter-layer insulation film 5 is formed on the covering insulation film 4, it is etched by using a photoresist pattern 6a formed thereon as a mask. In this case, since the projecting part of the covering insulation film 4 exposed on a connecting hole 7a is friable to etching, it is removed and then the inter-layer insulation film 3d thereunder is removed self-alignedly to make a connecting hole in a manner such that the upper surface of the wiring 2a is exposed.

Filed: 1992-08-19
Abstract: PURPOSE:To determine the scanning angle of an optical scanner highly accurately, to achieve the high accuracy of the optical scanner, and to make it possible to discriminate the signs of + or - of the scanning angle. CONSTITUTION:A resonance frequency signal Va (t) generated in a frequency generating device 5 is amplified with a piezoelectric driver 6, and the result is applied on an optical scanner 3. The phases of the deflection angle of the optical scanner 3 and the scanning angle theta (t) of a light beam are delayed by 90 deg. from the resonance frequency signal Va (t). Meanwhile, the resonance frequency signal Va (t) is differentiated with a phase adjuster 7, and the result is outputted as the scanning angle information Vc (t). The phase of the differentiated scanning angle information Vc (t) is delayed by 90 deg. from the phase of the resonance frequency signal Va (t). Thus, the scanning angle information Vc (t) is proportional to the scanning angle theta (t). Therefore, the scanning angle theta(t) can be readily found based on the scanning angle information Vc (t), and + or -of the scanning angle theta (t) can be discriminated at the same time.

Title: Method and device for adaptive synchronization for reproduction of digital video and audio data in multimedia reproduction system
Inventor: HUANG YAN
IPC: H04N21/43
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To reduce a backlog of video data by throwing away all other video information that is not required to reproduce a newest video image. SOLUTION: When a buffer 310 includes a video key frame being a backlog, a processor 330 allows a video decoder 314 to decode a newest key frame in a sequence of the backlog and to decode a key frame of other frames at the back of the sequence in the buffer 310. Then the processor 330 commands the video decoder 314 to decode only frames with highest sequence number in a video reproduction buffer 318. Finally the processor 330 commands a video player 820 to reproduce the frames decoded newest, resulting that only the frame being a backlog required for decoding the frames newest is decoded and only the frames decoded newest are reproduced and frames of other backlogs are effectively thrown away.

Title: Image formation type encoder using lens
Inventor: ITO YOSHINORI
IPC: G01D5/36
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To simply realize high resolution by executing electric division of a detection signal. SOLUTION: Slits 5 having a fixed width are formed at a fixed pitch on an scale plate 4 of this encoder, and each slit 5 is extended in the direction perpendicular to the moving direction of the scale plate 4. A slit transmitted light image (striped pattern of light and shade) obtained through the scale plate 4 is projected on four photodiode light-receiving face 11a-14a through a lens 6. The image forming position of the projected image can be set so as not to be positioned on the light-receiving face 11a-14a by adjusting distances (a), (b). As a result, a Lissajous's waveform of the projected image on the light- receiving face 11a-14a is brought close to a true circle, and detection signals A, B become a sine-wave shape. Therefore, the resolution of the encoder 1 can be heightened simply by executing electric division of the detection signals like these.

Abstract: PURPOSE:To correctly perform reverse compression connection by fixing a magnetic substance to the tip of a steel core exposed by stripping the end of a cable in step, fastening the steel core to an aluminum clamp, and detecting the distance to the steel clamp of an anchor metal with a magnetic sensor. CONSTITUTION:A magnetic substance 20 is fixed to the tip of the steel core of an aluminum cable steel reinforced(ACSR) which is stripped in step. The ACSR is inserted into an aluminum clamp 1, which is fastened by compression. A steel clamp 3 at the tip of an anchor metal 4 having a taper 5 is inserted into the aluminum clamp 1 through a jumper terminal 2. In this time, distance G1 and delta1 are determined based on the compression elongation of the aluminum clamp 1 and that of an aluminum strand layer 11 when the aluminum clamp 1 is reverse compressed. The aluminum clamp 1 is counter-compressed in this state to shorten the gaps to G2 and delta2. The gap delta2 is measured with a magnetic sensor 21 and a recorder 22. Thereby abnormal compression elongation of the aluminum strand layer 11 is detected and the reverse compression connection reliability improves.

Title: Analysis of thiamine and thiamine phosphates
Inventor: YASUI YOSHIHIDE
IPC: B01J20/281
Filed: 1988-09-29
Abstract: PURPOSE:To analyze thiamines with high sensitivity by using a column into which a packing material formed by bonding a hydrocarbon to a synthetic resin packing material or synthetic resin carrier is packed as the column of liquid chromatograph and adding EDTA to the mobile phase. CONSTITUTION:The column into which the packing material formed by bonding the hydrocarbon to the synthetic resin packing material or synthetic resin carrier is packed is used as the column of the liquid chromatograph and the EDTA is added to the mobile phase. Namely, the packing material formed by bonding the hydrocarbon to the synthetic resin packing material or synthetic resin carrier has less limitations on the pH of the mobile phase observed with the packing material formed of a silica gel as its carrier. The alkaline moving phase is usable for this packing material. The disturbance in the peak shape of the phosphates of thiochrome is improved by adding the EDTA (ethylenediaminetetraacetic acid) into the mobile phase and chelating the trace metal elements contained in the mobile phase passing the column. The thiamines are detected with the high sensitivity in this way.
