IPC: F02D41/22
Filed: 1982-06-07
Abstract: PURPOSE:To prevent strong shock by stopping the fuel supply after elapsing predetermined time when the engine rotation has reached to the level for preventing the over rotation prevention. CONSTITUTION:It is decided whether the engine rotation NE is higher than the over rotation preventing rotation NC at the step 102. Under over rotation, the count TD is up counted at the step 105. It is decided whether the count TD (delay time) has exceeded over predetermined level A at the step 106. If the response is YES, the valve open time signal provided to an injector is brought to zero at the step 107 to perform the fuel cut. Consequently strong shock will never be produced when the over rotation preventing function works.

Title: Controller for automatic transmission
Inventor: KOMODA TAKAO
IPC: F16H61/28
Filed: 1986-04-26
Abstract: PURPOSE:To reduce the shock on start and improve responsiveness by carrying out the switching to the largest speed change ratio on the basis of the engine load, when a shift lever is operated to an advance range from neutral. CONSTITUTION:A selected position instruction means F calculates the speed change stage which is temporarily achieved on the basis of the detection value of an engine load sensor E and instructs a switching means D to change speed. The switching means D for which the speed change stage is indicated temporarily instructs a speed change means B to switch the speed change when a shift lever operation detecting means C detects the operation from neutral range to advance range, and then instructs to switch the speed change to the min. speed stage, and the speed change means B performs the speed change switching. Therefore, when the engine load is small, speed change switching to the min. speed stage is performed temporarily through a low speed stage, while through a high speed stage when the engine load is large. In other words, when the engine load is small, switching is performed without interposing the high speed stage having a long speed change switching time.

Title: Gps receiver
Inventor: YAMASHITA YUZO
IPC: H04L7/08
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a GPS receiver which can shorten the time required until positioning is started by enabling the receiver to quickly establish synchronization with satellite data. SOLUTION: At the time of performing an in-satellite frame synchronization establishing process (a), it is required to acquire a plurality of pieces of synchronization establishing data existing in subframes appearing at six-second time intervals. At the time of performing an inter-satellite frame synchronization establishing process (b), on the other hand, the time intervals corresponding to the conventional six-second intervals become the differential time between the transmitting timing of the plurality of satellite data so as to discriminate the coincidence among the synchronization establishing data in the satellite data transmitted from a plurality of satellites. The differential time is about 20 milliseconds even when the altitude deviations of the satellites are taken into consideration.  Therefore, the frame synchronization can be realized earlier than the in-satellite frame synchronization by at least a minimum time (between six seconds and 20 milliseconds).

The ruggedness on the surface is thereby smoothed and the surface film is removed, by which the impurities in the film are removed and the factors to prohibit the migration of the atoms or molecules in the recording film are decreased. As a result, the speed of recording (erasure) is improved.
