Title: Accumulator type fuel injection valve
Inventor: KATOU MASAAKI
IPC: F02M47/02
Filed: 1984-03-15
Abstract: PURPOSE:To increase the pressure at the injection end than that at the injection start, decrease noises, and reduce the smoke occurrence by restricting the shift quantity of a needly valve via the pressure of a damper chamber. CONSTITUTION:When a needle valve 18 and a damper plunger 25 continue their lift in one body and the spindle 33 of the damper plunger 25 opens a spill port 34, the fuel in an accumulator chamber 13 flows into a damper chamber 24. Thereby, the fuel pressure in the accumulator chamber 13 is decreased and the pressure in the damper chamber 24 is increased. As a result, the pressure in a nozzle chamber 16 and the pressure in the damper chamber 24 arr balanced, and the needle valve 18 is abruptly pushed down by the force of a spring 23 to close an injection nozzle 17. Accordingly, such characteristics can be obtained that decrease the injection rate at the injection start and increase the injection rate gradually toward the injection end.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To improve constructing performance by inserting an RC slab with a water expansive sealant stuck thereto, into H-steel erected in an inclined state, then providing a form at the front face, and filling grout therein. SOLUTION: An RC slab 5 is inserted in an insert part 6 of an H-shape steel 1 erected in an inclined state. The RC slab 5 is provided with a water expansive sealant previously stuck to a contact place with a flange part of the H-shape steel 1. A form is disposed over the adjacent RC slabs 5 while covering the front faces thereof with the H-shape steel 1 held in between, fastening bolts inserted through bolt holes of the form are thread-fastened to internal threads, previously provided at the flange of the H-shape steel 1, to fix the form. Grout material is then filled in the form, and after solidification, the form is removed. In this case, an elastically deformable form is used as the form so that the form can be easily detached by the elastic spring action of the form when the fastening bolts are detached.  The RC slab can therefore be fitted to a steel structure positively and easily without looseness, and anticorrosion work taking plenty of time can be dispensed with.

Abstract: PURPOSE:To obtain a triple diffusion-type pnp-trsnsistor which has a large gain- bandwidth product fr and a small collector saturation voltage by a method wherein a current path region which has low resistance is formed in a collector region and if necessary a high concentrated connection region is provided also in a base region. CONSTITUTION:A high concentrated collector wall 10 is formed in a collector region 3 to extend to a p<+>-buried layer 4. The collector wall 10 is formed at the same time when diffusion of a p-type insulating isolation layer 5 is performed. Next thereto for a ohmic connection of a pnp-transistor's base an n<+>-layer 9 is formed at the same time when formation of an emitter region 1 of an npn-transistor is done, since wiring is performed with Al and Al is p-type dopant and ohmic contact can be hardly attained in an n-type impurity layer 2. By this construction a collector series resistance is surely reduced, and furthermore an ohmic contact of a base region is made to be perfect, the triple diffusion-type transistor which has large ft is obtained.
