Filed: 1989-12-05
Abstract: PURPOSE: To prevent deformation by providing the bottom of an injection port insert with a needle-like recess and directing the needle-like recess toward a moving valve portion, thereby forming a collecting chamber between the moving valve portion and the bottom. CONSTITUTION: The fuel injection valve has the moving valve portion 1. The valve portion is formed to a spherical shape and a conical stationary valve seat face 3 is formed at a nozzle body 2. The nozzle body is coupled to a valve casing 15. The moving valve portion 1 brings the valve seat of the valve seat face 3 into contact with 16 when the electromagnet of the fuel injection valve is not-energized. The valve portion is lifted from the valve seat 16 when the electromagnet is energized. Consequently, fuel flows between the moving valve portion 1 and the valve seat 16 and flows into the collecting chamber 13 having the min. volume. A receptive hole 4 is formed at the nozzle body 2 below a stopper surface 17 and the injection port insert 5 is press-fitted into the receptive hole 4.

In this case, the material first comes in contact with either blade part and then is sliced, or the material is sandwiched between the two blade parts 13 and 14, when the blade edge is blunt. A gap between the aforesaid blade parts 13 and 14 narrows as the rotary disc 11 rotates and, therefore, the material slides on a blade surface while strongly pressed to both blades parts 13 and 14. Namely, the aforesaid pressing force and slide effect are applied from the blade surface to the material, thereby enabling the maintenance of cutting quality of the blade parts 13 and 14.

Title: D/a conversion system
Inventor: HAYASHI SHIGEYOSHI
IPC: G11B20/10
Filed: 1988-12-14
Abstract: PURPOSE:To decrease the distortions of a small signal and to eliminate a trimming job by changing the distortion factor of the small signal into a lower factor in the direction of a large signal at D/A conversion and then magnifying the distortion factor of the small signal at magnification and at the side of a magnifier circuit in the direction of the small signal with a function adverse to that used for the compression of data. CONSTITUTION:A digital data compressing circuit 1 applies the uniform compression of data to the digital value before conversion into the audio signal at the directional digital stage of a large signal level and gives the D/A conversion to the A/D conversion via an n-bit D/A conversion circuit 2. At this A/D conversion the distortion factor of a small signal is changed into a lower in the level direction of the large signal. Thus the distortion factor of the small signal is reduced at the D/A conversion. Then the D/A-converted signal is amplified in the direction of the small signal at amplification with a function adverse to that used for the compression of data carried out at the side of an amplifier circuit 3. Thus the D/A-converted signal is reset to the level of the original audio signal. As a result, the original audio signal can be restored with substantially no distortion. Thus the distortion of the small signal is improved and no trimming job is required.

Abstract: PURPOSE:To increase the operation margin of a sense amplifier by connecting a constant current circuit in series with a start transistor (TR) so as to make the operation of the constant current circuit independent of a power voltage thereby limiting a current from a latch signal line at the starting to a prescribed value. CONSTITUTION:Plural signal generating circuits each consisting of TRs Q5, Q7 whose 1st input/output terminal are connected to a power supply line and whose control terminals are connected to clock signal lines P1, P2 and of the constant current circuits Q6, Q8 inserted between a 2nd input/output terminal and a latch signal line S are provided. Then different clock signals from each signal generating circuit are applied to the clock signal lines P1, P2. A depletion MOSFET Q6 is inserted between the source of an enhancement MOSFET Q5 and a ground power supply line to bring the potential of the gate the same as that of the source. Thus, the latch signal generating circuit is operated stably by a constant current absorbing capability without power supply voltage dependancy at the starting and then the current capability of the circuit is enhanced by using the MOSFETs Q7, Q8 to attain stable high speed operation.

Abstract: PROBLEM TO BE SOLVED: To reduce the required time to configure a field programmable gate array(FPGA) by providing an external interface including plural serial channels receiving simultaneously plural serial data streams. SOLUTION: A PLD(Programmable Logic Device) 100 includes a control logic circuit 101 and plural logic blocks 102 configure substantially identically to each other.

Furthermore, each of the logic blocks 102 is much smaller than the entire chip and identical but independent. Thus, each of the programmable logic blocks 102 is configured simultaneously by connecting to a single line among plural data buses 103a-103c. Thus, the time to configure the FPGA at an installation site is reduced and the physical space of the device is miniaturized.

Title: Dust boot mounting method
Inventor: TAKAHASHI NAOMI
IPC: F16J15/52
Filed: 1993-11-22
Abstract: PURPOSE:To improve durability and productivity of mounting by a method wherein a mounting jig having a disc-shaped roller locked rotatably radially of a shaft is caused to effect one or more full rotation in one-way around an axis, a dust boot is mounted in a peripheral groove part in a state that the small opening part of the dust boot is pressed by a roller. CONSTITUTION:When the large opening part 7 at the one end of a dust boot 4 is fixed pressed in the peripheral recessed part 22 of a housing 3, the outside diameter, extending to an end face 18, of a handle part 17 is covered with the inner peripheral end part of a small opening part 9 at the other end. The end part of a roller 14 is then brought into contact with the outer peripheral end part 24 of the opening part 9 and is caused to press to the outer position B of a peripheral groove part 5. The center of the base 10 of a mounting jig 1 is positioned coaxially with the axis of a shaft 2 and at least one or more full rotation is performed in a one-way. Since the roller 14 and the outer peripheral end part 24 are brought into contact with each other in one spot, the roller 14 is caused to effect follow rotation, and the opening part 9 is fitted in the peripheral groove 5. This constitution prevents the damage of the dust boot during mounting of the dust boot, improves durability, performs reliable mounting, and improves productivity of mounting.
