Title: Fuel injection valve
Inventor: MIZUNO YOSHINORI
IPC: F02M61/18
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection valve to prevent failure of a fuel spray state by restraining deflection of a bottom part of a bottomed cylindrical part at the time of fuel injection. SOLUTION: A nozzle plate 61 is press fit and fixed in a sleeve 71 so that an out side end surface 61d of a bottom part 61a and an end surface 26a of a valve body 26 make contact with each other face to face by forming the bottom part 61a of the nozzle plate 61 formed in a cup shape so as to project outside by specified quantity and reducing the projection quantity by elastic deformation. Consequently, it is possible to restrain deflection of the bottom part 61a due to fuel injection pressure by reaction force working in the cup outside direction generated as the bottom part 61a of the nozzle plate 61 is pressurized in the cup inside direction. Accordingly, it is possible to restrain formation of a clearance between the valve body 26 and the nozzle plate 61 due to deflection of the bottom part 61a at the time of fuel injection and to prevent failure of a fuel spray state due to this clearance.

Title: Control system for head position of magnetic reproducing device
Inventor: SATOU MASAHIRO
IPC: G11B5/55
Filed: 1982-02-26
Abstract: PURPOSE:To shorten the positioning time of a head and to improve operability, by driving a motor at a high voltage up to right before a target position of the head and driving the motor at a low voltage thereafter, and thus braking the motor excellently. CONSTITUTION:The output of an output line 27 is at L and a transistor (TR)26 is off, so the motor 1 rotates a fast at a 11.3V high voltage. The output of a photoreflector 18 is applied to a control circuit 12 through a Schmitt circuit 15 and counted. Consequently, the control circuit 12 detects the head arriving at a pause position PAUSE and holds the output of the output line 27 at H. Consequently, the TR26 turns on, the output of a constant voltage circuit 24 drops to 7V, and the motor 7 rotates while having inertia reduced by low-voltage drive. The moment the head passes by the position PAUSE, the output of the photoreflector 18 is at H and when it arrives at a play position PLAY, the output goes down to L. At this time, the output of output lines 21 and 22 are both at H, so the feeding to the motor 1 is stopped through a driving circuit 20.

Title: Rolling method with controlled draft percentage
Inventor: TSUBOTA KAZUYA
IPC: B21B1/38
Filed: 1980-03-11
Abstract: PURPOSE:To manufacture a rolled product in nearly exact rectangular shape even from a defectively shaped feed stock, by so adjusting the roll gap that the longitudinal distribution of sectional area can be obtained correspondingly to the shape of the rolled product running out of the rolling pass accomplished with a controlled draft percentage. CONSTITUTION:The breadth of a slab as a feed stock is actually measured or is obtained by the on-line computation. If the slab is a partly shapecorrected one, the equivalent breadth of slab is actually measured. Next, the sectional area of intermediately rolled product, corresponding to the aimed plane shape of the final rolled product, is obtained by applying the correction for the equivalent salb breadth to the sectional area of the rolled product, operated from the formula for forecasting the sectional area of the rolled product from the actually measured breadth and shape. From thus obtained longitudinal distribution of sectional area of an intermediately rolled product, the longitudinal distribution on necessary sheet thickness is obtained. Then, the screw position (roll gap), corresponding to thus obtained necessary thickness, is obtained. Thereby, even in the case of using such a defectively shaped slab as a partly shape-corrected slab, a breadth-tapered slab, etc., the rolled product in the exact rectangular shape can be manufactured.

The small piece 5 is pressed back by a spring located inside a lower die. In the state that the small piece 5 and the tips of the inner leads 3 are retained mutually, the lead frame is welded to a ceramic substrate 15 coated with glass 14. When the small piece 5 positioned at the center is pulled upward under the condition by using a small hole 8, each divided piece of the small piece 5 is welded to the substrate without affecting each other and with the positional dimensions of the tip of each inner lead remaining to be the dimensions of punching by a press, and, in this way, the small piece can be removed. By this constitution, imperfections due to the positional slippage are not caused at the time of automatic connection.

CONSTITUTION:A storage rack position span is divided into a zone L and a zone R in advance. When a transfer command 1 from an address P to an address Q is emitted out of an upper device 17, a storage rack address detecting circuit 20 of an accesser controller 18 detects the specified storage rack address, inputting it into an address comparator 22. This comparator 22 reads a boundary address 21 as well and also judges that the storage rack belongs to either of these storage zones L and R from a comparison between the storage rack address and the boundary address. And, an accesser driving circuit 26 or 27 at the specified side is driven whereby an accesser 3 or 3' is transferred. With this constitution, handling capacity and reliability both are improvable.

Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To conduct a following operation, which follows a seek operation, using a less amount of power consumption for a driving system of a head carriage device. SOLUTION: A head carriage has a magnetic head slider 42 in the tip end of the carriage. The carriage has a main magnetic driving device 51 having a large torque constant and a submagnetic driving device 60 having a small torque constant. During a following operation following a seek operation, a first controller 81 generates an eccentric component compensating current 'a' to compensate for an eccentric component of a magnetic disk 45. The device 51 is driven by the current 'a', the head carriage is operated and the slider 42 follows up the eccentric component of the disk 45. A second controller 82 generates a compensating current 'b' to compensate for a residual positional error which is left after the compensation of the eccentric component of the disk 45. The submagnetic driving device 60 is driven by the current 'b' and the slider 42 follows up a track.  Thus, the power consumption is made less compared to the case in which a following operation is conducted by the device 60 alone.

Abstract: PURPOSE: To obtain a high-frequency surface acoustic wave(SAW) by using a substrate at a high acoustic velocity by utilizing the SAW in the manner of leaked wave, for which the acoustic velocity is turned to be specified-fold in comparison with a Rayleigh wave, as resonance frequency or a filter frequency among SAW excited by an electrode. CONSTITUTION: Concerning the SAW element for which a comb-shaped electrode is formed on the substrate in the X direction propagation of a rotary quartz board Y, the SAW in the manner of leaked wave, for which the acoustic velocity is turned to be 1.6-fold or 1.8-fold in comparison with the Rayleigh wave, among the SAW excited by the electrode is defined as the resonance frequency or filter frequency. Namely, sprious is generated near the 1.6-fold and 1.8-fold Rayleigh wave at all the elements. Afterwards, these waves are called 1.6-fold wave and 1.8-fold wave. These 1.6-fold wave and 1.8-fold wave are close to the high velocity of lateral and longitudinal waves and when a surface is damped, both the waves are attenuated down to a noise level. In this case, when designing the element at the same frequency, a large electrode pitch can be secured.
