Title: Liquid crystal video projector device
Inventor: KANETANI MIDORI
IPC: G09G3/36
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To eliminate adverse effect that is caused by the dust attached to an optical system to an image projected on a screen by adhering airtightly a glass plate of the prescribed thickness on the end face of a glass rod integrator set at its outputted and preventing the dust attached on the said end face from being projected on the screen. SOLUTION: The light sent from a light source H01 travels straight on a center line and goes toward a glass rod integrator H04, and the light radiated in the side direction is reflected on a reflecting surface of an elliptic reflector H02 and goes toward the integrator H04. An ultraviolet/infrared cut filter H03 is placed between the light source H01 and the integrator H04 to eliminate the harmful components such as the ultraviolet and infrared rays which are contained in the light sent from the light source H01. The light incident on the integrator H04 is transmitted through a glass plate H05 and goes into a relay lens H06. Then the plate H05 is adhered to the lens H06 to form no air gap on the light emitting surface of the integrator H04.

Abstract: PURPOSE:To shorten molding cycle, while the occurrence of the sink mark in the blank hole or the surface of a boss part is prevented by a method in which the gaps communicating with the gap for feeding cooling blast are provided in between a core pin and a sleeve pin, and the core pin inserted into the blank hole of the boss part is cooled by the cooling blast blowing through these gaps. CONSTITUTION:A molded object 13 and a less part 16 are molded by a cavity 11, a core 12, a sleeve pin 14 and a core pin 15, and the cooling blast flowing through gaps 18, 19 is applied to the core pin 15 in contact with the blank hole of the boss 16. The heat is transmitted to the core pin 15 from the blank hole of the boss part 16, but the core pin 15 is cooled by the cooling blast applied to the core pin 15, hence the boss part 16 is cooled from the bottom hole, whereby the occurrence of the sink mark in the bottom hole or on the surface of the boss part 16 may be prevented, and simultaneously its molding cycle may be shortened. The boss part 16 shrinks by the cooling blast for cooling, and a gap is generated is between th boss part and one end of the sleeve pin 14. According by, the cooling blast whose temperature has been elevated, is discharged to atmosphere through the gap between the boss 16 and the sleeve pin 14 and the gap 20 between the sleeve pin 14 and the core 12.

Abstract: PURPOSE:To decrease the fluctuation in shape, film thickness and film quality of a spacer and thus control the occurrence of crystal defects in edge portions by forming an oxide film by LOCOS using a silicon nitride as a mask that serves again later for formation of a spacer. CONSTITUTION:A silicon nitride film 4 of a predetermined pattern is formed on a silicon oxide film 2 by CVD. A field oxide film 3 and a transistor spacer oxide 3' are formed by an improved LOCOS technique. With the field oxide film masked by a photoresist film, the oxide film 3' is masked by the silicon nitride film 4 for both isotropic and anisotropic etching. The remaining part after the etching forms a spacer 6. The width of the spacer is constant because it is determined by the silicon nitride pattern 4. The spacer has a uniform quality owing to the LOCOS technique. The transistor is protected from the damage due to the injection into the source and drain because of the small contact angle between the substrate 1 and the spacer 6.
