Title: Disk device
Inventor: OGASAWARA FUMIO
IPC: G11B7/09
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To enable a light spot to accurately follow the center of a track, i.e., its target despite a fast relative speed that is set when the light spot crosses the track and also to shorten the wait time that is required for a tracking servo lead-in operation. SOLUTION: This disk device includes a tracking error detection circuit 4 which generates a tracking error signal TE of a sine wave form corresponding to a moving direction that is orthogonal to the center line of a track formed on an optical disk 1, a sum signal detection circuit 5 which generates a sum signal QS having its phase different from the signal TE by 90 degrees and an arithmetic processor 8 which generates the approximately linear position error value having the prescribed inclination from both signals TE and QS which are digitized by the A/D converters 6 and 7 and also generates a scan controlled variable signal CNT for the light spot formed by an optical pickup 3 to trace its target track according to the position error value.

Title: Contact hole
Inventor: YAZAKI MASATOSHI
IPC: H01L21/768
Filed: 1987-12-21
Abstract: PURPOSE:To form a good junction and to prevent a defect of a junction by a method wherein two layers, i.e. a doped silicon layer and a tungsten layer on the layer, are formed inside a contact hole and a wiring substance is joined to the tungsten layer inside the contact hole so that silicon of an impurity diffusion layer on the side of a substrate cannot be consumed during a formation operation of the tungsten layer. CONSTITUTION:Doped silicon 4 by selective deposition of a first layer and tungsten 2 by selective deposition of a second layer on the first-layer doped silicon 4 are formed inside a contact hole; the contact hole is filled. Because the first-layer doped silicon 4 exists, the first-layer doped silicon 4 is consumed without shaving off silicon of an impurity diffusion silicon layer 6 on the side of a substrate when the second-layer tungsten 2 is deposited selectively. The first-layer doped silicon 4 contains an impurity of high concentration; its resistance value is low; accordingly, it is possible to join the second-layer tungsten 2 to the impurity diffusion silicon layer 6 on the side of the substrate.

Title: Automatic analyzing device
Inventor: SANO KAZUTAKA
IPC: G01N35/02
Filed: 1989-12-13
Abstract: PURPOSE:To reduce a waste of a sample and a reagent by dispersing the reagent and a sample in a reaction container, and continuing to measure a sample which is already stirred even if a dispensation part or stirring part becomes abnormal and obtaining measurement data. CONSTITUTION:A sample cup 1 is installed on an inspected body rack 2, mounted on a rack conveyance device 3, and conveyed to the sample dispensa tion, and the sample is dispensed in the reaction container 6 from a sample dispensing probe 4 by a specific amount. Then the reagent is added from the reagent dispensation part and stirred by a stirring device 14 and when the they passes in the luminous flux emitted by a light source 15 at a light measure ment part, a multiwavelength photometer 16 detects the absorbance; and its luminous intensity signal is processed by a computer 19 and the concentration is measured. At this time, if the dispensation part or stirring part becomes abnormal, a reaction table 7 is so controlled that devices parts regarding rotat ing operation, measuring operation, and measurement data processing continue to operate. Thus, a sample having advanced to a light measurement point is measured without being discarded, and thus utilized effectively.

Title: Waterproof structure
Inventor: TABATA MASAAKI
IPC: H01R13/52
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To improve the waterproof performance by preventing the uneven distortion of a rubber plug. SOLUTION: A tubular rubber tube 50 penetrable by a wire 20 forms a waterproof part 51 which can be contacted closely on the inner peripheral surface of a terminal metal fitting housing 11 to be a wire leading-in hole, at one end side divided in the axial direction, and an engaging part 52 forming a first flange 52a and a second flange 52b is provided at the other end side. By pinching with clamping pieces 61 and 61 forming semicircular holding grooves 62 and 62 corresponding to the engaging part 52, the first flange 52a is entered into the engaging grooves 62a in the holding grooves 62 and pinchedly held by covering the whole periphery by engaging the projections and the recesses impossible to displace in the axial direction.  As a result, the rubber tube 50 can be held solidly without generating an uneven distortion to the engaging part 52 itself, so as to generate no uneven distortion as in case of pressure contacting by the barrel of a terminal metal fitting. Consequently, it is unnecessary to exercise the waterproof property more than necessary by assuming such a distortion.

Title: Synthetic resin molding die
Inventor: TANAKA JUNJI
IPC: C23C14/34
Filed: 1987-12-24
Abstract: PURPOSE:To facilitate the releasing of a synthetic resin molded item from a molding die and obtain the synthetic resin molded item, which is excellent in mirror-smoothness without clouding or the like by a method wherein a fluorine-containing metallic film is formed on the molding surface of the molding die by sputtering in fluorine-containing gas atmosphere. CONSTITUTION:A fluorine-containing metallic film is formed on the molding surface of a molding die by sputtering in the atmosphere of fluorine-containing gas such as fluorine gas, carbon tetrafluoride, tetrafluoroethylene and the like. In case of the surface of glass, which is normally used as mold material, since etching or cleaning by the order of several Angstrom  - several ten Angstrom  is developed by means of ionized fluorine, the improvement of the adhesion of the film to the mold material results. Further, the deficiency of fluorine, which occurs during the formation of the film is replenished. Or, since fluorine-containing polymerized film is present in the film, low stress composite is produced, resulting in allowing to form fluorine-containing metal excellent in releasability.

Title: Control method for voltage type vvvf inverter
Inventor: NUMANO TOSHIO
IPC: B60L3/00
Filed: 1990-11-29
Abstract: PURPOSE:To suppress ripple voltage of an input capacitor and to reduce the capacity and the size of the input capacitor by performing phase difference operation between inverters connected in series. CONSTITUTION:A phase difference of 30 deg., for example, is set between the control signals for unit inverters 411 and 421. Consequently, the voltage ripples have phase difference of 180 deg. between both inverters and thereby they are canceled each other thus producing no ripple voltage in a combined input voltage. The ripple voltage is suppressed most at a phase difference of 30 deg. and it can be suppressed according to an appropriately selected phase difference. Since the voltage ripple is suppressed, inductance of an input filter reactor can be decreased.
