Title: Noise eliminator for booster
Inventor: IKEDA MASAHIRO
IPC: B60T13/52
Filed: 1994-03-31
Abstract: PURPOSE:To reduce an intake air sound without sacrificing responsiveness of a booster by forming a recesss-projection surface on an inside surface of a cylindrical part of a shell, and reducing a collision sound generated when pressure fluid flowing in a voltage transforming chamber collides with the inside surface of the cylindrical part. CONSTITUTION:A synthetic resin annular member 35 is pressed in and fixed to an inside surface of a cylindrical part 2a formed on a rear shell 2. Plural annular grooves 35a extending in the circumferential direction are formed on an inner peripheral surface of the annular member 35, and a recess-projection surface is formed. The annular grooves 35a may be formed in the parallel direction or even in the oblique direction, or may be formed even in a grid shape. When a brake pedal is stepped down and pressure fluid is introduced to a voltage transforming chamber D through a voltage transforming passage 21, since it collides with the recess-projection surface in the cylindrical part 2a of the rear shell 2, a collision sound is reduced, and an intake air sound is reduced. Since flowing resistance of the pressure fluid becomes smaller than when a sound absorbing material is arranged in a pressure passage, a sacrifice of responsiveness is also reduced.

Abstract: PURPOSE:To enhance a productivity by a method wherein a film or a layer composed of a low-melting metal (low-melting alloy) is melted on the side of a high-temperature part and is cooled on the side of a low-temperature part of a high-boiling liquid in a container. CONSTITUTION:When a high-boiling liquid in an inner-tube upper part 25 is heated by using a heater 20, a specific gravity of the high-boiling liquid 8 in the upper part 25 inside a heated tube 19 is made small and is not circulated by convection together with the high-boiling liquid 8 of a low temperature whose specific gravity is large in the lower part and is circulated by convection only in the upper part. As a result, a part in the inner-tube upper part 25 on the inside of the tube 19 is set to a high temperature and a part in an inner-tube lower part 26 is set to room temperature; and a temperature gradient is formed. Accordingly, chip components 7 which have been thrown into by using a supply apparatus 9 fall in an individually separated state; their plated films of electrodes are melted in the heated inner-tube upper part 25; they fall to a low-temperature part; their melted parts are solidified; treated chip components 17 having electrodes whose surface is smooth fall to the bottom of the tube 19 and are collected inside a conveyance container 23. Thereby, a large-quantity and high-speed treatment can be executed; and a productivity can be enhanced.

Filed: 1989-04-05
Abstract: PURPOSE:To effectively extinguish an arc by installing a fixed contact and forming a gas room in a bottomed-cylindrical shielding equipped with an insertion hole, as an opening, to airtightly insert a movable contact. CONSTITUTION:A gas room 17 is formed in the inside of a first shielding 1 such that a cylindrical partition 16 surrounding a fixed contact 5 is fixed with one end of the cylindrical partition 16 on the bottom of the first shielding 1. A piston 14 is installed in such a state that the external boundary of the piston 14 is made to movably come into contact with the internal boundary of the partition 16. Therefore, when an insulated gas heated and pressure-elevated by arcing which occurs between the fixed contact 5 and a movable contact 15 at the initial time of disconnection pushes the piston 14, a pressure hole 22 is opened by movement of the piston 14 with the result that the insulated gas moves from the pressure hole 22 to the gas room 17 and the pressure of the gas room 17 increases. When the movable contact 15 comes out of an insertion hole 4a of an insulation nozzle at the latter time of disconnection, the piston 14 is pushed back by the tensile force of a spring 20 to close the pressure hole 22 and concurrently, the insulated gas of the gas room 17 is discharged to the outside of the shielding from the insertion hole 4a, and blown against the arc. Thereby, the arc can be effectively extiguished.
