Title: Method of removing resin in emergency
Inventor: YASUHARA SHIGEKI
IPC: C08G81/02
Filed: 1987-12-15
Abstract: PURPOSE:To carry out removal of a resin in an emergency without causing gelation using a simple inexpensive apparatus, by casting a liquid resin into a frame for the resin situated on a cooling belt when the liquid resin produced in a reactor is to be removed in an emergency. CONSTITUTION:A reaction is carried out in a reactor to produce a liquid resin. In case of emergency such as power failure, a discharge valve 4 of the reactor is opened, and the liquid resin 3 is discharged at a stretch and is cast into a resin holding frame 2 situated on a cooling belt 1, where it is cooled by the cooling belt. Since the discharged liquid resin 3 is enclosed in the resin holding frame 2, there is no possibility that the liquid resin flows down from the cooling belt 1, and thus the liquid resin is cooled and solidified slowly by the cooling belt 1.

IPC: B60H1/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce an air blowing noise by uniformizing the flow of air running toward a suction port of an air blowing casing by a guide part. SOLUTION: An air flow guide part 13d projecting to the rotary shaft 13c side is formed on an inside surface of a circumferential wall 13a of a rotary door 13. This air flow guide part 13d guides the flow of air running toward a suction port 21 after being introduced from an inside air introducing port 11 or an outside air introducing port so as to be uniformized, and is composed of plural projecting parts 13e and 13f formed in a waveform and a recess- projection shape on an inside surface of the circumferential wall 13a. When introducing air tries to flow along the inside surface of the circumferential wall 13a, the flow of introducing air can be forcedly deflected to the lateral side from the central side of an air fliter 30 and the suction port 21 by the air flow guide part 13d.  As a result, air is distributed at almost uniform wind speed over the whole surface of the air filter 30, and the upstream side air flow of the air filter 30 is straightened, and since turbulence of the air flow is minimized, a noise by the turbulence of the air flow can be reduced.

Title: Ink jet record head
Inventor: FUJII MASAHIRO
IPC: B41J2/045
Filed: 1990-11-21
Abstract: PURPOSE:To improve frequency response characteristic, make driving voltage low, and reduce dispersion of head property by making the shape of a piezoelectric device curved before adhesion and making it smooth by adhering to the surface of a pressure chamber of a substrate. CONSTITUTION:A second substrate 2 is welded to a substrate 1 integrally and shuts off a passage 10 and a reservoir 14 so as to seal ink. A piezoelectric device 16 is previously formed in a curved shape and adhered to an upper position of a pressure chamber of the substrate 1 on the surface of the second substrate 2. As the piezoelectric device 16 has the curved shape, it is restrained to be flat due to the adhesion to the second substrate 2. At this adhesion, the piezoelectric device 16 generates an internal stress caused by the restraint and generates an electric charge on the surface at the same time. However, this electric charge is discharged freely soon and dissipated, so that the piezoelectric device 16 will have only the internal stress. A conductive member 3 adhered or evaporated on the surface of the second substrate will be a common electrode of the piezoelectric device 16. Thus, frequency response characteristic will be improved, driving voltage will be low, dispersion of head property will be reduced, and print quality will be improved.
