Title: Fuel injection device of internal combustion engine
Inventor: IWANAGA TAKASHI
IPC: F02M47/00
Filed: 1992-11-18
Abstract: PURPOSE:To prevent the change of the fuel injection for the exciting current of a solenoid valve according to the interval of a plurality of fuel injections in a fuel injection device of an internal combustion engine where the fuel required for each combustion of the internal combustion engine is injected by being divided into a plurality of parts. CONSTITUTION:The exciting pulse P1 for pilot injection is outputted by TP1, the magnetic force of a solenoid valve exceeds H0 a little later. The pressure in the operation chamber is reduced, and when this pressure drops below Pr1, the pilot injection is started. When the exciting pulse P3 is outputted by TD1, the pressure in the operation chamber is also reduced, but the pressure in the operation chamber is changed to be increased before reaching Pr1 as the pulse width is small in P3. Thus, the fuel injection is not executed, and only the magnetic force remains. When the exciting pulse for the main injection is outputted in TM1, the magnetic force imediately reaches H0 and the main injection is executed with the lag time of T0. That means, the same lag time is obtaines as that when the interval between the pilot injection and the main injection is small.

Title: Fine cap measuring apparatus
Inventor: KOSHIMOTO YASUHIRO
IPC: G11B21/21
Filed: 1988-12-08
Abstract: PURPOSE:To enable measurement of an absolute distance of a fine gap at a high accuracy continuously in a wide range by emitting at least two lights with different wavelength to one optical system for detecting interfering light repeatedly in sequence. CONSTITUTION:Laser diodes 4A and 4B oscillate in emit light at different wavelengths. The lights pass through a beam synthesizer 7 and a beam splitter 8 and are focused at one point of a head 2 arranged under a glass disc 1 from an objective lens 12. Light reflected on the surfaces of the disc 1 and the head 2 are changed in optical path with a polarization prism 9 through the lens 12 and a collimator lens 11 to be detected with a photo detector 6. Then, a fine gap formed on the surface of the head 2 and the surface of the disc 1 can be measured from an intensity detected with the photo detector 6, a reflection factor of the surface of the glass disc 1, that of the surface of the head 2 and a wavelength of light by a specified expression. Thus, a simultaneous measurement accomplished by the same optical system depending on at least two wavelengths thereby enabling continuous measurement at a high accuracy in a wide range.

Filed: 1988-12-08
Abstract: PURPOSE:To reduce a contact movable resistance at the time of arming and to execute smooth arming which does not obstruct a musical performance property by constituting a turning supporting point of a pin-like member and a recessed member. CONSTITUTION:In the case of executing the arming, a tremolo arm 8 is brought to up-and-down motion operation arbitrarily. By this operation, tension of a string 6 and a spring 10 is not balanced, that is, the tension of the string 6 becomes strong and weak and a musical interval goes up and down. This arming operation is executed by turning a tail piece 3 by using a turning supporting point 11 as a turning point, and this turning supporting point 11 is constituted of a pin-like member 12 in which a curved part 15 is formed in the tip, and a recessed member 13 having a recessed part 16 whose diameter is larger than the diameter of the curved part 15. In such a way, the contact movable resistance in this supporting point is small, and accordingly, arming is executed smoothly.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a scratch by a claw part of a glove ring by fitting a flange into an annular recessed section with a clearance and constituting a front end of a cylindrical pipe cover into an inclined part directed toward an inner side of a socket to cover the claw part of the glove ring. SOLUTION: When a resin pipe 30 is inserted into a socket 10, a tip of the resin pipe 30 presses an inclined part 22 of a cylindrical pipe cover 20, and the cylindrical pipe cover 20 moves by a length of a clearance between an annular recessed section 140 and a flange 21 together with the resin pipe 30 in this condition to cover a claw part 130 of a glove ring 13. Consequently, when the resin pipe 30 is inserted toward a deep section, it does not come in contact with the claw part 130 of the glove ring 13 directly, and is further inserted while the cylindrical pipe cover 20 comes in contact with the claw part 130 . In this way, an outer surface of the resin pipe 30 is not scratched by the claw 130 of the glove ring 13.

Title: Display device driving circuit
Inventor: SATO TOSHIMI
IPC: G09G3/296
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To provide a technology capable of reducing the chip size in a scanning driver of PDP(plasma display panel). SOLUTION: This display device driving circuit 1 has a buffer circuit 12, an nMOS14 and a reverse blocking diode 51 and is constituted so that electric charges in a PDP can be discharged by allowing the nMOS14 to be turned on/off by the output of the circuit 12. Even when a large current is made to flow through the nMOS14 and a parasitic diode 41 in the circuit 12 is forward- biased, since the diode 51 is made to be reverse-biased and a current is not allowed to flow through the diode 41, the potential of the gate terminal of the nMOS14 is not clamped and the gate terminal and the drain terminal of the MOS14 become the same potential. As a result, even when a small nMOS15 is used in this circuit, since sufficient current driving capability can be obtained, the chip size can be reduced.
