IPC: H04L7/00
Filed: 1991-02-22
Abstract: PURPOSE:To extract a correct timing by sampling a reception pulse at its peak, to prevent deterioration in an S/N and to extend the transmission distance inevitably. CONSTITUTION:A reception pulse sampled at a speed twice the transmission speed by an A/D converter 2 is delayed respectively at 1st and 2nd delay circuits 3, 4.

Title: Chair with rockable back
Inventor: GIANKARURO PIRETEI
IPC: A47C1/022
Filed: 1992-02-14
Abstract: PURPOSE: To prepare a simple compact chair with an up-to-date design by incorporating a mechanism to combine the weight of a seated person with a reaction force into a structure of a seat part. CONSTITUTION: The lower end of a frame 8 lifts the rear part of a seat part 6 because of the largest rear reclining of the back rest 4 of a chair, so that the seat part 6 swings about the front side axis 12. A thrust mechanism slides in a tubular element 10 by the swing of the frame 8 about the axis A to compress a coiled spring 40. The back rest 4 of the chair applies a force to the back of a seated person. This force depends on the load of the spring 40 and the weight of the seated person. Thus, the swinging rigidity of the back rest 4 is adapted automatically to the requirement of the seated person. The whole mechanism to connect the seat part 6 to the back rest 4 is put in the tubular element 10. Thus, the chair is very compact and overlaid on another chair of the same kind.

Title: Manufacture of semiconductor device
Inventor: FUKAMI AKIRA
IPC: H01L21/223
Filed: 1988-02-12
Abstract: PURPOSE:To reduce the amount of impurity to diffuse outwards and to prevent the impurity concentration in a polythetaSi layer from reducing by a method wherein an impurity is fed at the time of annealing of a structure made by forming a WSi2 layer on the polythetaSi layer, in which such an impurity as B, P or As is introduced. CONSTITUTION:An Si oxide film 2 is formed on an Si substrate 1 and a polythetaSi layer 3 doped with such impurity as B, P or As and a WSi2 layer 4 are formed thereon. In the case of annealing of this laminated structure, the outward diffusion of impurity is easy to occur in the annealing after the opening of a contact hole 6 for making a contact with an upper wiring layer, so the annealing after the opening of the hole 6 is performed in an impurity-containing atmosphere. Thereby, the impurity is fed in the layer 4 in the hole 6 as shown by an arrow 7, the impurity concentration in the layer 4 is increased and diffusion of the impurity from the layer 3 to the side of the layer 4 is inhibited. Moreover, the contact of a metallic silicide with Si, which is a semiconductor, can be turned into an ohmic contact and the resistance itself can be also reduced.

Abstract: PURPOSE:To reduce collisional noise so as to obtain a solenoid valve of excellent durability by causing an elastic protrusion to first abut against a stator core or plunger when the plunger is absorbed to the side of the stator core by means of transmission of electricity to the coil. CONSTITUTION:An elastic protrusion 10A is formed integrally with the outer peripheral then wall portion 10a of an elastic body 10 and is made to protrude in the direction where it abuts against the end face 8a of a stator core 8. The protrusion length of the elastic protrusion 10A is set such that when the elastic protrusion 10A is deformed by a predetermined amount the outer peripheral thin wall portion 10a is next made to abut against the end face 8a of the stator core 8. When the plunger 9 is absorbed the elastic protrusion 10A is therefore made to first abut against the end face 8a of the stator core 8 to absorb the energy of collision between both of them, thereby reducing collisional noise. The outer peripheral thin wall portion 10a of the elastic body 10 is next made to abut against the end face 8a of the stator core 8 to deal with the electromagnetic force increased, thus reducing the facial pressure of the valve and also making the valve one with excellent durability.
