Title: Semiconductor device
Inventor: HAMADA HITOMI
IPC: H01L21/60
Filed: 1988-12-28
Abstract: PURPOSE:To prevent moisture from reaching the electrode pad and avoid the corrosion of the electrode pad by a method wherein unevenness is provided on a metal wire connecting the electrode pad of a semiconductor element to an extraction terminal and the length of the moisture penetration path between the electrode pad of the semiconductor element and the extraction terminal is prolonged. CONSTITUTION:Unevenness is provided on a metal wire connecting the electrode pad of a semiconductor element to an extraction terminal. For instance, the part 11a and the part 11b of the metal wire have different diameters to provide unevenness on the surface of the metal wire. By providing the unevenness like this, the distance from the extraction terminal to the electrode pad of the semiconductor element is prolonged compared with the distance of a conventional constitution, so that moisture can hardly penetrate and the corrosion of the electrode can be avoided.

A comparator 6 outputs a difference between the monitor voltage and a reference voltage Vref. A switching element 81 in a sample and hold circuit 8 is turned ON by a controller 7 only during the period in which the light is output from the element 3. Accordingly, the difference between the monitor voltage and the voltage Vref during the period in which the light is emitted from the element 3 is stored in a capacitor 82 in the circuit 8. The voltage stored in the capacitor 82 is fed back to the circuit 2 as the control voltage.

Title: Filter regenerator of internal combustion engine
Inventor: NITTA MASAHIRO
IPC: F01N3/028
Filed: 1990-11-29
Abstract: PURPOSE:To improve regeneration efficiency of a filter regenerator by collecting particulates in exhaust gas by means of a filter, dielectrically heating them by means of a micro wave oscillator, oxidation burning them by an air supplying means, and controlling the micro wave oscillator and the air supply means in such a manner to get rid of overlapping of the operation time band of the oscillator to that of the air supply means. CONSTITUTION:When an engine 11 is driven, a filter 13 begins to collect particulates. When an exhaust gas temperature is increased to a predetermined value or more, a control valve 16 causes the exhaust gas to flow in a by-pass pipe 18, and a magnetron 21 dielectrically heats the particulates in the filter 13 by a micro wave. When the temperature reaches a self combustion temperature of the particulates or more, the magnetron 21 is stopped, an air pump 19 supplies air for combustion from the micro wave supply direction to the filter 13 to burn the particulates by oxidation. The position of a control valve 20 is changed to supply air from the opposite direction to the filter 13 and restrict the combustion when the temperature exceeds a predetermined temperature range, so as to prevent damage of the filter 13 by heat. When a temperature increasing value is decreased at the final stage of the combustion, the magnetron 21 is stopped to end a regeneration operation.

Filed: 1994-12-16
Abstract: PURPOSE: To enhance accuracy of judgement of a normal traveling state and pneumatic pressure by correcting a detected wheel speed through a correction coefficient obtained therefrom for a tire movement radius, judging the normal traveling state based on the correction value, and collecting data used for pneumatic pressure judgement from the detected car speed at the time of normal traveling state. CONSTITUTION: A control unit 50 receives signals of wheel speed sensors 51-54, an initial setting switch 55 of pneumatic pressure judging variable or the like, and performs calculation to drive-control a warning lamp 56. Namely, wheel speeds obtained from the wheel speed sensors 51-54 are corrected by a correction factor of tire movement radius dispersion calculated based thereon. A normal traveling state is judged by using this corrected wheel speed, and at the time of the normal traveling state, wheel speed data to be used for tire pneumatic pressure judgement are collected from the signals of the wheel speed sensors 51-54.  Consequently, the normal traveling state can be judged accurately and quickly without being influenced by dispersion of the tire movement radius, collection of the wheel speed data used for pneumatic pressure correction can be promoted and accuracy of pneumatic pressure judgement can be enhanced.

Title: Direct current restoration circuit
Inventor: KAWABATA ETSUO
IPC: H04N5/16
Filed: 1988-12-30
Abstract: PURPOSE:To prevent an uncomfortable feeling from being given to a viewer even at an abnormal time or transient time, in which a horizontal pulse is not outputted, by impressing a direct current level when there is no horizontal pulse. CONSTITUTION:When a horizontal pulse (a) is stopped being inputted to an A point and the potential of the A point is made 'L', an electric charge is not charged to a capacitor C1 and the base voltage of a transistor Tr1 is made 'L'. Then, the transistor Tr1 is turned to an OFF state. Thus, a partial voltage to be determined by a power source voltage B1, resistance R2, the regular direction voltage of a diode D3 and resistance R3, namely, the 'H' level higher than the threshold level of an RGB circuit 30 appears at a B point. Thus, a diode D2 is reversely biased and turned to the OFF state. Thus, when there is no horizontal pulse, the reference level is not held constant. However, since the charge voltage charged to the coupling capacitor of a color difference signal output circuit is not discharged and the level is lowered only for the charged voltage, the picture of a receiver is changed in a direction where the picture is made dark.

Abstract: PURPOSE:To obtain such a door stop having a buffer efficiency, a low collision sound with a door, excellent in airtightness and sound insulating efficiency, easily detached and not easily influenced by a size error of fitting channels in a door frame. CONSTITUTION:A door stop 1 is constituted of a longer bar-shaped body 2, a plurality of buffering elastic tongue pieces 3 projected from one side of the body and a plurality of force-fit legs 4 projected from the sides of a door frame of the body 2. The whole door stop is a monolithic moulding of foamable vinyl chloride resin.

Title: Attraction and repulsion type generator
Inventor: KAMIMURA ICHIRO
IPC: H02K23/66
Filed: 1990-11-29
Abstract: PURPOSE:To reduce cost and miniaturize its size by giving a positive, zero, or negative AC current to a coil magnet, which has an optional phase, so as to make it an optional or neutral polarity, and thereby moving a rotor or a mover. CONSTITUTION:When drive power is led from an input brush 2 to a positive electrode slip ring 3, a brush 4 for output becomes an anode, and a coil 5 is excited. For example, if one pole piece 6 becomes an N pole, the magnetic pole piece 7 of the opposite polarity becomes an S pole, and the current flows through the other output brush 8 into negative slip ring 9 by irregularity, and returns to the driving power source 1 passing through the other input brush 10. When this is repeatedly rectified, the rotor 11 is attracted and repelled by the stator, and rotates continuously. Accordingly, by optionally setting, for example, magnetic pole pieces to six sheets, the permanent magnets of a rotor to four poles, or magnetic pole pieces to twelve poles vs. permanent magnets eight poles, it becomes a single-phase or three-phase synchronous motor.

Abstract: PURPOSE:To form an org. dye layer and a polymer layer at the same time and to enable wide selection of materials by coating a substrate with a coating material prepared by dissolving the org. dye and the polymer which are insoluble to each other into one solvent. CONSTITUTION:On a transparent substrate 1 in which guide grooves are formed as required, the org. dye layer 2 which absorbs semiconductor laser light to effect photothermal conversion, the polymer layer 3 to protect the dye layer 2 are successively laminated. The org. solvent used for preparation of the coating material is properly selected from org. solvents used in the field of optical recording and from those compounds that have enough solubility to both of the org. dye and the polymer and give no damage on the substrate. As for the org. dye, those used in the filed of optical recording can be used, but it is required that the dye is insoluble with the polymer. Thereby, the uniform org. dye layer is formed without damaging the substrate, which improves the reliability of the medium.
