Title: Adjusting method for fuel injection device
Inventor: MATSUMURA TOSHIMI
IPC: F02D41/40
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To solve the problem of a long adjustment time and high cost caused in performing a conventional adjustment with special emphasis placed on accuracy, which is largely affected by adjusting procedures of correction values of the following three types: a pilot injection finish correction value (1), a main injection start correction value (2), and a main injection finish correction value (3), necessary for an adjustment of errors in pilot injection and main injection. SOLUTION: The respective pilot correction values (1), (2), and (3) are written in a pump ROM attached onto a fuel injection pump. The determination procedure of corrections determines the pilot injection finish correction value (1) for adjusting the pilot injection amount, the main injection start correction value (2) for adjusting a pilot interval, and the main injection finish correction value (3) for adjusting a total injection amount, so as to correct the pilot injection amount, the pilot interval, and the total injection amount. It is thus possible to attain high injection accuracy, a short adjusting time, and the cost reduction in adjustment because a single adjustment of the main injection amount is eliminated.

Title: Three-dimensional shape measuring instrument
Inventor: ISHIMARU ICHIRO
IPC: G01B9/02
Filed: 2001-02-19
Abstract: PROBLEM TO BE SOLVED: To measure the three-dimensional shape of a body to be measured over a relatively wide range in a short time without contacting. SOLUTION: The direct reflected light (0th-order light) of the reflected light generated when the body to be measured is irradiated with light is guided by a discriminating optical system to a variable-phase filter and the high-order diffracted light is guided to a fixed reflection part; and they are reflected respectively and converted by an interference optical system on nearly one point to interfere with each other. In this state, a movable reflection part of the variable-phase filter is moved within the range of the wavelength of light in use and then the phase of the 0th-order light which is reflected there gradually shifts from the phase of the high-order diffracted light which is reflected by the fixed reflection part, so that the interference light of both the lights at the image formation point of the interference optical system gradually varies in intensity.  The position of the movable reflection part of the variable-phase filter at the maximum intensity point of the interference light depends upon the distance between the starting point (reflection point) of the body to be measured and the movable reflection part, so the position of the starting point can be calculated from the position.
