IPC: G09F9/00
Filed: 1987-08-04
Abstract: PURPOSE: To enable a viewer to see reflected light from a screen as a picture by arranging a transmission type liquid crystal element like a character pattern or a matrix according to the purpose and throwing light from an light source system placed in the rear and placing an optical system using a leans in the front. CONSTITUTION: This video machine forms an image on a screen (d) by using the structure where a transmission type liquid crystal element (a) is arranged like a character pattern or a matrix according to a purpose and is irradiated with light from a light source system (b) placed in the rear and an optical system (c) like a lens is placed in the front. When a cooler of the light source, a controller for the stop and the focus, a zoom mechanism consisting of an optical system having a variable focal length, a filter acting upon light from the light source, or the like is added to the machine, the function is stabilized to improve the usefulness. The size of the liquid crystal element is arbitrary in principle, but it is preferable in consideration of the resolution or the like that the size is about 0.1 to 100cm<2> .  The size of the screen is dependent upon the size of the liquid crystal element and the performance like the resolution, but the screen of several cm<2> to several m<2> is easily realized.

Title: Radio communication system
Inventor: TAKI KAZUYA
IPC: H04W72/04
Filed: 1996-07-24
Abstract: PROBLEM TO BE SOLVED: To permit a master set to connect respective slave sets to respective external lines so that they can make communicate with simple control without switching transmission/reception by making communication between the transmis sion parts of the respective master sets and the reception parts of the respective slave sets and communication between the transmission parts of the slave sets and the reception parts of the respective master sets with different frequencies. SOLUTION: The second slave set 135 receives information which the master set 10 transmits by a transmission slot Tb after hop time passes in a reception slot Rb. At that time, the master set 10 transmits a frame constituted of hop time and the transmission slot Tb to the second slave set 135 as one unit and the second slave set 135 receives the frame constituted of hop times and the reception slot Rb from the master set 10 as one unit. The master set 10 synthesizes the transmission signal of the transmission slots Ta and Tb in a synthesizer and transmits it from an antenna through a transmission/reception separation unit. At that time, the transmission signal of the transmission slot Ta is a frequency band A and the transmission signal of the transmission slot Tb is a frequency band B.  Then, they are not overlapped and therefore the transmission signal is prevented from being damaged in the synthesizer.

Abstract: PURPOSE:To hold generation of step differences on the surface of a substrate and crystal defects at the minimum limit by a method wherein poly-Si surrounded with a thin SiO2 film is buried in an element isolation region. CONSTITUTION:Ion etching is performed to the N type Si substrate 4 to provide a perpendicular groove, and the thin SiO2 film 5 is formed. Generation of the crystal defects is held at the minimum limit because thickness of the film is not necessitated. Then the extremely narrow groove is filled up with poly-Si 6 according to the CVD method, and poly-Si 6 on the surface is etched to be removed to leave poly-Si 6 in the groove. N ions are implanted in high concentration in poly-Si 6 in succession using an Si3N4 mask, and the mask is removed to complete. By this constitution, the step differences on the surface of the substrate and the crystal defects can be held at the minimum limit.
