IPC: B41J2/18
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus capable of certainly performing cleaning operation for sucking and discharging ink from the nozzle orifices of a recording head. SOLUTION: In a capping means having a function sealing the nozzle forming surface of a recording head to apply negative pressure, a cap holder 9 and a cap member 7 are formed, for example, by a two-color molding method. The seal part 7b coming into contact with the nozzle forming surface is formed so as to cover the reinforcing rib 9e formed to the cap holder 9 and constituted so that a part thereof fills the engaging hole 9f having the anchor part 9j formed to the cap holder 9. By this constitution, the seal part 7b of the cap member 7 can be effectively prevented from falling inwardly, for example, by negative pressure at a time of cleaning operation and the cap member 7 receives negative pressure to be effectively prevented from the peeling from the cap holder 9.

Title: Piston prober
Inventor: SAITO MASAHARU
IPC: G01F25/00
Filed: 1987-11-17
Abstract: PURPOSE:To simplify the piping of the piston and to measure and test the error of a flowmeter efficiently in a short time by providing a supply path connected to a supply pipe and a receiving pipe in a piston which moves reciprocally in a cylinder. CONSTITUTION:When the piston 5 moves from the left side to the right side in a figure, a space F is put under high pressure, a space E is put under negative pressure, and the check valve 12 (or 13) of an opening part D (or B) is opened (or closed) on the side of a supply path 5a. On one discharge path 5b, on the other hand, a slide type check valve 14 closes (or opens) an opening part A (or C). Water which is sucked from a suction hose 34 through the supply pipe 15, therefore, fills the space E through the supply path 5a and an opening part D. Then when the piston 5 moves in the cylinder 4 from the right side to the left side, said various valves, etc., operate reversely to send to water in the space E to a space F. Then when the piston 5 moves to the right, a specific amount of the water in the space F is sent out of the opening part C to the sending pipe 16 through the sending path 5b. Consequently, water is supplied into the cylinder 4 and the water supplied to the cylinder 4 is discharged from the cylinder 4 at the same time as the piston 5 moves in one direction.

Title: Lining
Inventor: KURAUSU BUIIRANTO
IPC: C03B5/42
Filed: 1991-08-16
Abstract: PURPOSE: To increase the quantity of heat supplied to a material to be heated by reducing the direct reflection of radiant heat by forming the wall surfaces of a depression, in such a way that the radiant heat from one wall surface comes into collision with the other wall surface and, in addition, is absorbed into a lining brick. CONSTITUTION: Each lining brick 1 has a plurality of notches 2 open onto the internal space 4 of a furnace. The bricks 1 are assembled in such a way that the adjacent two notches 3 of each adjacent bricks 1 form a depression 5 which opens onto the internal space 4 of the furnace in an opened cross section A. The depression 5 has side walls 7 continuously formed from a bottom 6 which is formed in such a way that the radiant heat which comes into collision with the bottom 6 from the internal space 4 is reflected to the side walls 7 and absorbed into the side walls 7. Since most of the heat is reflected by the lining bricks 1 in the depression 1 in such a way, the direct reflection of the radiant heat to the internal space 4 of the furnace is reduced.  Therefore, the heat absorbed into the lining bricks 1 is discharged into the internal space 4 and effectively supplied to a material to be heated.
