IPC: B29C45/76
Filed: 1984-05-22
Abstract: PURPOSE:To prevent gas generating in melting of plastics and lubricant mist, etc. from diffusing into clean room provided with an injection molding machine by a method wherein a collecting hood provided near an injection nozzle is connected with an exhaust duct discharge exhaust. CONSTITUTION:When the plastics injection molding machine 14 is in motion, gas generating in melting of plastics leaks from the end of the injection nozzle 15.

IPC: B01D53/86
Filed: 1995-04-27
Abstract: PURPOSE: To improve the bonding strength of a bonding section between a flat sheet and a corrugate sheet and further improve the durability of a honeycomb body by winding up the flat sheet of low bending strength and the corrugated sheet of high bending strength concentrically and alternately to form a cylindrical honeycomb body, heating the honeycomb body and brazing contact sections of the flat sheet and the corrugated sheet. CONSTITUTION: The bending strength of a material for a flat sheet 2 is made lower than that of a corrugated sheet 3, and the flat sheet 2 and the corrugated sheet 3 are wound alternately to form a cylindrical honeycomb body 1, and a brazing material is fed to contact sections of the flat sheet 2 and the corrugated sheet 3. The honeycomb body 1 is exposed in the vacuum at high temperature of, e.g. approximately 1200 deg.C for, e.g. approximately 30 minutes to melt and spread the brazing material allover on the contact sections of the flat sheet 2 and the corrugated sheet 3, and then the honeycomb body 1 is cooled slowly. The bending strength of the flat sheet 2 and that of the corrugated sheet 3 are almost equal to each other, and large thermal stress is not generated concentratedly on either the flat sheet 2 or the corrugated sheet 3 after heating. Thereby the durability of the honeycomb body can be improved.

When the detected temperature rises above the specific value, an indication which allows the solenoid valve 6 to close the oil path 3 and open the oil path 3 is sent to an electromagnetic switch 9 and heted hydraulic oil is cooled by the exchanger 5. Thus, the oil temperature of the hydraulic oil is held static.

Title: Image recorder
Inventor: TAKADA AKIHIKO
IPC: G03G21/20
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain high image quality without density dispersion and fog, and also to obtain sufficient reliability and durability, in an image recorder for forming electrostatic latent image with a pyroelectric effect. SOLUTION: When the surface of the pyroelectric body layer 1 of a latent image charge holding medium 3 is selectively heated according to an image signal by a thermal head 4, a polarized charge inside disappears by heating and a negative charge stuck to the surface is made free and further, escapes to an earth potential, so that a charge is immediately neutralized to form the electrostatic latent image. At the time of attaining development with toner, generally the temp. of a developing part is made lower than that of a latent image forming part, the polarization of the charge by cooling becomes great and a stuck toner quantity is larger than a desired one, to cause the fog.  Thus, a developing part heating means 28 is controlled by referring to the temperature data of temperature sensing elements 25 and 26, by a temperature control circuit 27 and the difference between the temperatures of the developing part and the latent image forming part can be kept constant.
