Abstract: PURPOSE:To improve the starting characteristics by executing the pilot injection at a timing selected to have fuel collide against the wall of a cylinder only and the main injection at a timing selected to have fuel carried into a cavity when an engine is cranked. CONSTITUTION:In a multi-cylinder diesel engine 1 a nozzle 11 faces to the cavity 3a of a piston 3 for each cylinder 2. The nozzles 11 is connected to a fuel injection pump 20 via a high pressure pipe. In this case a control unit 30 controls the fuel injection pump 20 according to the detected signal of a starter sensor 52 as a means for detecting the time at which the engine 1 is cranked. At the time of the cranking, the pilot injection from the nozzle 11 is executed at the timing when fuel collides against the wall of the cylinder 2 and not against the top face of the piston 3. The main injection from the nozzle 11 is executed at the timing when fuel is carried into the cavity 3a.

Title: Measuring method of lifetime of carrier
Inventor: KOYAMA MASATO
IPC: H01L21/66
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To measure the lifetime, having high spacial resolution, of the microscopic region of a semiconductor film.

Title: Information presenter and navigation system
Inventor: MATSUDA NORIO
IPC: G08G1/0969
Filed: 1995-03-16
Abstract: PURPOSE: To make information presentable in resorting to a feeling other than both visual and hearing senses by installing a movable part, capable of coming into contact from the outside, and a means controlling a driving means according to the presenting information, respectively. CONSTITUTION: In a car navigation system, turning information is presented by an audio-visual sense information presenting means (a speaker, a monitor or the like) while attention awakening information is also presented in an audio- visual sensing manner. A driver recognized with this attention-awakening information audio-visually comes into contact with a movable part at once, whereby he is able to secure route guide information tactually. In brief, a stick 710 as the movable part is installed in a stick driver 700 so as to be projected to the outside, therefore this stick 710 can be touched from the outside.  For example, in the case where information to be turned to the right at an intersection is presented, the stick 710 is vibrated as long as about one second, then the stick 710 is rocked to clarify the bending direction and this state is maintained as long as about 0.5 second or so. In consequence, any burden and restrictions on the driver necessary for securing the route guide information are lightened.
