Title: Accumulator type fuel injection device
Inventor: OKAMOTO ATSUYA
IPC: F02M51/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To stabilize behavior of a 2-way valve while maintaining a constitution of top return by reducing a pressure of leak fuel. SOLUTION: In an armature upstream chamber 2 or in a leak passage 8 leading to an armature upstream chamber 2 from a control chamber 1, a rubber material 5 internally containing air serving as a pressure absorbing means is provided. When fuel coming out of the control chamber 1 reaches the lead passage 8 or the armature upstream chamber 2, by the rubber material 5 internally containing air serving as the pressure absorbing means, a pressure is reduced, a differential pressure between the armature upstream chamber 2 and armature downstream chamber 3 is decreased. Accordingly, force received by an armature 41 is reduced, behavior of a 2-way valve is stabilized, which effectively improve the accuracy of a fuel injection amount.

Title: Magnetic disc device and access control method thereof
Inventor: KATSUMATA MAKOTO
IPC: G11B19/02
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To restrict increase in access time by switching a head so as to read out a cylinder address from another second disc recording surface for minimizing the delay in the speed control when the cylinder address fails to be read out accurately. SOLUTION: When it is determined by a cylinder address judging section 81 that a cylinder address fails to be read out accurately, the cylinder address judging section 81 sends no data of the cylinder address to a head moving speed detecting section 82 and directs a head switching section 85 to switch a head. As a result, the switching section 85 outputs a head switching signal S to a head amplification circuit 6 to switch a disc recording surface desired to read out a servo data part over to another disc recording surface. In addition, a timing is generated to detect the servo data part from the disc recording surface after the switching and preparations are made for the subsequent detection of the servo data part.
