Title: Control device of variable valve-timing mechanism
Inventor: MIYAKOSHI TATSU
IPC: F01L1/34
Filed: 2002-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To prevent responsivity from changing due to dispersion of resistance in rotational-phase change in a variable valve-timing mechanism in which the rotational phase of a camshaft is displaced in the directions of the retard and advance angles by the braking power of electromagnetic brakes.  <P>SOLUTION: In the variable valve-timing mechanism, a response time actually taken by the rotational phase is measured in the convergence in following to a stepping change of a target rotational phase. If the measured response time is over a required time, a feedback gain (a differential gain) is renewedly learned. In the renewed learning of the gain, if an overshoot is caused within the response time, the gain is decreasingly corrected so as to shorten the response time by suppressing the overshoot. In the case of no generation of overshoot, the response time is reduced by incremental correction of the gain.  <P>COPYRIGHT: (C)2003,JPO

Title: Method for forming fine glass particle deposit
Inventor: YOSHIDA MOTOHIDE
IPC: C03B37/018
Filed: 2002-01-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for forming a fine glass particle deposit by adding a dopant (F) simultaneously; not by impregnating the dopant by heating the fine glass particle deposit formed already under the atmosphere of the dopant lowering the refractive index.  <P>SOLUTION: A fine glass particle deposit with a lower refractive index than that of the core base glass is formed by the OVD or VAD method around the periphery of the core base glass. The glass deposit added by the dopant is formed by passing the material gas (CF<SB>4</SB>) of the dopant lowering the refractive index together with the glass material through the port of the burner synthesizing the fine glass particle, where the glass material is also passed. This method reduces the production cost by cutting the process impregnating the dopant under its atmosphere into the fine glass particle deposit formed without the addition of the dopant.  <P>COPYRIGHT: (C)2003,JPO
