Title: Forced cooling device for internal combustion engine
Inventor: YUKIYOSHI TOORU
IPC: F01P5/04
Filed: 1980-04-08
Abstract: PURPOSE:To eliminate the necessity of an additional power transmission element other than a fly-wheel secured to a crankshaft and a fan provided with an outer peripheral ring to provide a cooling device at a reduced cost by resiliently contacting the fan against the outer periphery of the fly-wheel in order to allow the fan to be rotated directly by rotation of the fly-wheel. CONSTITUTION:A crankcase 1 has a hub 2 formed on one side thereof. An end of an arm 3 is mounted at 4 for pivotal motion on the hub 2. An axial-flow type fan 5 which has a ring 6 integrally provided on an outer periphery thereof and is molded with a synthetic resin or the like is rotatably supported at 7 on an end of the arm 3. A spring 8 is extended between the crankcase 1 and the arm 3 to resiliently urge the arm 3 towards one side of the crankcase in order to resiliently contact the ring 6 of the fan 5 against the outer periphery of a fly-wheel 10 secured to a crankshaft 9. By this construction, the ring 6 is followingly rotated by rotation of the fly-wheel 10 so that winds produced by the fan 5 are blown against a cooling fan 13 to thereby cool a cylinder 11 and so on.

Title: Control system for direct-injection spark-ignition internal combustion engine
Inventor: TOMITA MASAYUKI
IPC: F01N3/20
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To promote early activation of an exhaust emission control catalyst for a direct-injection spark-ignition internal combustion engine to the utmost while minimizing the emission of HC into the atmosphere between an engine start and that catalyst activation. SOLUTION: For such combustion as using an engine intake mixture of a stoichiometrically controlled air-fuel ratio between an engine start and activation of an exhaust emission control catalyst, a fuel injection in a suction stroke forms a relatively lean homogeneous mixture rather than a stoichiometric one within a combustion chamber and a fuel injection in a compression stroke forms a relatively rich stratified mixture rather than a stoichiometric one about the spark plug to thereby offer stoichiometric stratified combustion. This constitution raises the ratio of CO easy to oxidize and lowers that of HC to oxidative materials included in burned gas, to thus promote oxidation by the exhaust emission control catalyst and further early activation thereof while minimizing the emission of HC into the atmosphere between an engine start and that catalyst activation at the same time.

Title: Printing data generating apparatus
Inventor: GOTO JUNICHI
IPC: B41J5/30
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent the abnormality of printing output caused by the data insufficiency in an FIFO memory provided to the output stage of a general purpose personal computer even when the general-purpose personal computer is utilized as a printing data producing apparatus for a laser printer. SOLUTION: When the accumulated data quantity of an FIFO memory 7a is reduced to fall below a scheduled threshold value and this state is detected by a monitor means 80, a data processing restriction means 90 issues an operation interrupting command to the lower decoding part 50n of a decoding means 50. As a result, the reading of the lower n-bit compression data 31n from a memory means 40 by the lower decoding part 50n is interrupted and a surplus is generated in a bus 10 by the quantity corresponding to interruption. Therefore, the reading of the upper n-bit compression data 31m from the memory means 40 by one upper decoding part 50m is substantially performed at a high speed.

Title: Automatic steering device
Inventor: HIROSE TOSHIROU
IPC: G05D1/02
Filed: 1980-04-09
Abstract: PURPOSE:To improve the performance of an automatic steering device by using the specific magnetism sensor consisting of magneto-sensitive elements and a DC power source. CONSTITUTION:A magnetism sensor 2 is formed into a bridge circuit by ferromagnetic magneto-sensitive thin-film elements, 6A, 6A, 6B, 6B and the respective elements are made on the same plane, for example, a printed substrate. This bridge circuit is fixed to a coordinate axis 5, that is, a hull 4. If a DC power source 1 is applied to one of the bridge circuit, the voltage Etheta which is the function of the angle theta of the coordinate axis 5 with respect to a magnetic needle 3 is obtained from the other. A driving circuit 8 is operated by this signal, whereby automatic steering is accomplished. If the DC power source 1 normally installed to a small- sized hull is connected to such sensor 2, the angle information Etheta which is a full direction signal is obtained. In this way, the circuits are made simple and trouble- free and since no rolling of the hull is detected, the performance is improved.

Title: Optical pickup device
Inventor: TAKAHASHI YOSHITAKA
IPC: G11B7/13
Filed: 1990-02-28
Abstract: PURPOSE:To detect relative inclination between an optical information recording medium and an optical pickup part without receiving an effect caused by the deviation of the optical axis of an objective lens by providing a photodetector for detecting inclination on the condensing point of light reflected from the optical information recording medium. CONSTITUTION:When coma aberration occurs to a spot on a magneto-optical disk 5 as the result that the relative inclination occurs between the disk 5 and the optical pickup part, the effect of the coma aberration A appears also on the quadripartite photodetector 10. Due to that, the inclination in a tracking direction T and a jitter direction J can be detected. Besides, even when the optical axis of the objective lens 4 is deviated, the condensing position on the photodetector 10 is not changed and hardly affected by the coma aberration. As the result, a relative inclination detection signal can be detected without receiving the effect by the coma aberration at all even when the optical axis of the objective lens 4 is deviated.
