Title: Bonding method for components of thermal ink jet printing head
Inventor: PIITAA JIEI JIYON
IPC: B41J2/16
Filed: 1993-03-31
Abstract: PURPOSE: To seal hermetically an air gap between a manifold and a print head and thereby to enhance a state of structural combination of the manifold with structural elements of the print head. CONSTITUTION: A through hole 54 is formed in a radiating base plate 40 and this through hole 54 is made to communicate with a cavity 56 demarcated by a manifold 26. In assembling, this manifold 26 is set on the upper part of the base plate 40 including a print head die 38 and a connecting board 28, and held by pins. An encapsulation fluid is injected into the cavity 56 from the lower part of the base plate 40 through the through hole 54. When this fluid flows in the vicinity of the front of the print head 38, the injection is stopped. Thereby encapsulation of a wire bond is conducted and an air gap between the manifold 26 and the print head 38 is closed up along the front.

Title: Liquid crystal projector
Inventor: OGAWA MASAHIRO
IPC: G02F1/13357
Filed: 1990-03-26
Abstract: PURPOSE:To prevent display contrast from decreasing and liquid crystal from breaking thermally by providing a heat insulation wall which is equipped with a light transmission window between a light source part and a liquid crystal panel. CONSTITUTION:The heat insulation wall 19 equipped with the light transmission window 19a is provided between the light source part 14 and liquid crystal panel 13. The light transmission window 19a is provided with an infrared-ray removing filter (infrared-ray reflecting filter or infrared-ray absorbing filter) 18 and the illumination light from the light source part 14 is made incident on the liquid crystal display panel 13 after the infrared-ray removing filter 18 removes its infrared-ray components. Therefore, the heat radiated by the light source part 14 is cut off by the heat insulation wall 19, so the liquid crystal display panel 13 is never exposed to the radiant heat from the light source part 14. Consequently, a rise in the temperature of the liquid crystal display panel is suppressed low to prevent the display contrast from decreasing and the liquid crystal from breaking thermally.
