Title: Variable valve system
Inventor: FUJIMOTO MASAHIRO
IPC: F01L13/00
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve drivability of an internal combustion engine in an intermediate and low speed region mainly by changing an opening period of an intake valve or an exhaust valve in an initial time of changing process when an operating condition of the internal combustion engine is changed from a low speed operation to a high speed operation. SOLUTION: When a phase angle of a control disk 14 is regulated from 360 deg. (low speed downward eccentricity) to 180 deg. (high speed upward eccentricity) in the case where an engine operating condition is changed from a low speed side to a high speed side, opening periods of an intake valve and an exhaust valve are increased effectively. Especially, a control disk 14 is rotatively driven, the opening timing of the exhaust valve is advanced as well as the closing timing of the intake valve is delayed, and then, the closing timing of the exhaust valve is delayed as well as the opening timing of the intake valve is advanced. The phase regulating direction of the control disk 14 is set, and thereby, it is possible to provide a smooth torque curve so as to sharply improve a drivability in a low and intermediate speed rotating region mainly.

Title: Cylindric magnetic domain element
Inventor: HIDAKA YASUHARU
IPC: G11C11/14
Filed: 1977-10-14
Abstract: PURPOSE: To improve the bubble cut-off capacity for the hook-shaped pattern by setting the vertical angle of the first chevron column in the first branched transfer path smaller than the veritical angle of the first chevron column in the second branched transfer path.  
     CONSTITUTION: The bubble is transferred from the right side of the diagram along the transfer path is changed to magnetic domain 6 in an extended form at chevron column 1 and then divided into two parts right after reaching over chevron column 7 and 8. In this case, a difference is given as shown in the diagram for the vertical angles between the first chevron column 7 and 8 in branched transfer path 3 and 4. As a result, the phase range is narrowed for the rotary magnetic field where the bubble is trapped into bar-shaped pattern 5 via column 8, and is then widened by column 7 so that the bubble is trapped near the right edge of column 7. Therefore, one end of the bubble is at near the center of column 8 as for the rotary magnetic field phase, and the other end is at the right edge of column 7 respectively. Thus, the bubble cut-off capacity can be enhanced for the hook-shaped pattern

IPC: B24B37/005
Filed: 1987-05-22
Abstract: PURPOSE:To prevent lowering of grinding, by providing a means to detect a force exerted on a workpiece during machining to separate it into a first force exerted in the direction of a normal and a second force exerted within a main surface as resistance, and a control means to control the first force to a desired value based on the detected two forces. CONSTITUTION:A load is detected from a resilient ring 8 by a dynamic strain gauge by means of component force in a horizontal direction (a tangential resistance force Ft) and a component force in a vertical direction (Fn in the direction of a normal). The load enters a microcomputer 11 from an amplifier 9 by means of an A/D converter 10, and an amount instructed through a mechanism drive device 12 is fed as a feed in a vertical direction to a moving table 16 through a column 14 and a ball screw by means of a stepping motor 13. When, for example, choking occurs to a grinding stone 1 during machining, a grinding force is lowered, and a force in the direction of a normal is rendered ineffective, by perceiving a change in the force, a vertical load is increased to specify a grinding speed (rate). When an unreasonable force is exerted on a workpiece, a load is decreased, where an occasion demands.

CONSTITUTION:A phase shifter 4 generates signals Vl, V2 whose phase difference is 90 deg. from an input signal Vi. The signals V1, V2 are given to the double balanced differential amplifiers 5, 6. A control voltage Vx is converted into a difference current Ix by a voltage/current converter 8. The current Ix is formed into a control voltage DELTAV1 by a logarithmic conversion means 9 to control the gain of the amplifier 5. Further, the current Ix is given in the circular function conversion means 10, where the current is converted into a current Iz having a relation of Ix<2>+Iz<2>= constant, the current Iz is formed into a control voltage DELTAV2 by the logarithmic conversion means 11 to control the gain of the amplifier 6. Since the gain of the amplifiers 5, 6 is controlled in this way and subject to vector addition at an adder 7, then an output signal Vo of a constant amplitude within the phase change of + or -90 deg. is outputted at an output terminal 2.
