Title: Method for driving pile to hard sandy ground
Inventor: HAYASHI KATSUAKI
IPC: E02D5/46
Filed: 1989-01-10
Abstract: PURPOSE:To increase resistivity against drawing-out with increased thrusting force by uniting a pile, driven in to a prescribed depth by a combined method using a vibro pile driver and jetting water ejected from a water-convying pipe, with the ground around the driven-in pile. CONSTITUTION:A batter pile 2 is driven into a hard sandy ground 1 up to a prescribed depth by a combined method using a vibro pile driver equipped with a vibro hammer 3 that is installed to a batter-pile-driving leader 12 and jetting water ejected from a nozzle at the tip of a water-conveying pipe 5. When the jetting water from the water-conveying pipe 5 is replaced with high- pressure cement milk M and only the water conveying pipe 5 is drawn out while the cement milk is injected. Then the cement milk M is mixed with sandy soil that is disarranged by injection of the jetting water around the batter pile 2, and soil cement body 13 is formed thereby around the batter pile 2. Thereby the batter pile 2 and the soil cement 13 are united together, increasing resistivity against drawing-out.

IPC: H04N19/00
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain the image coding method in which a code quantity of a stereo image signal is reduced.

Title: Magnetostriction type torque sensor
Inventor: MURAKAMI TAKU
IPC: G01L3/10
Filed: 1988-01-08
Abstract: PURPOSE:To easily detect torque without requiring a large mount space, by detecting the torque acting on a transmission shaft by a detector for detecting the magnetic flux generated by the strain of a magnetostriction material caused by the torque acting on the transmission shaft. CONSTITUTION:A magnetostriction material 2 is bonded to the entire peripheral surface of a transmission shaft 1 by an adhesive so that the crystal direction thereof is matched with a main stress direction. When strain is generated in the material 2 corresponding to the torque applied to the shaft 1, the magnetic flux corresponding to strain is generated by Pyrheli's effect. Since the magnetic flux in a coil 3 changes by the rotation of the shaft 1, when a switch 5 is closed, the voltage corresponding to the torque acting on the shaft 1 is generated in a voltmeter 4. Since the torque applied to the shaft 1 is proportional to the voltage generated in the coil 3, when the voltage generated in the voltmeter 4 is measured, the torque acting on the shaft 1 is detected. By this method, torque is easily detected without requiring a large amount space.

Title: Control unit of direct-injection internal combustion engine
Inventor: MITSUMOTO HISASHI
IPC: F02D41/02
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To solve such a problem as worsening those of drivability and exhaust composition, especially hydrocarbon discharge by installing a compensation means compensating a span of ignition timing in the timing delay direction in time of misfire detection at the stratified combustion, in a device which makes an engine perform the stratified combustion by mainly spraying fuel at the latter half of a compression stroke at the specified driving area. SOLUTION: A control unit 11 is equipped with an air flow meter 12, a crank angle sensor 13, a water temperature sensor 14 or the like, and it controls those of fuel injection quantity, injection timing and fuel pressure on the basis of a signal out of a driving state detecting means. At a low speed, low load area, a stratified combustion is carried out by mainly spraying fuel at the latter half of a compression stroke, and at the driving area other than that, the fuel is mainly sprayed to a suction stroke, through which a harogeneous combustion is carried out. At this time, after those of fuel injection timing and ignition timing at a stratified driving state are determined, a fact of whether there is a complete misfire or not is judged. If the misfire has occurred in this time, the ignition timing is compensated in the timing delay direction.  With this, a span of carburetion time for fuel injection is prolonged and an air-fuel ratio of mixture in and around a spark plug is leaned, and thus a problem on any possible misfire is solved in this way.
