Title: Multidirection multiplex radio communication system
Inventor: FUJIOKA SHIGERU
IPC: H04B1/68
Filed: 1980-11-26
Abstract: PURPOSE:To transmit audio and information signals at a station or between two stations at the same time, by transmitting an audio signal through eliminating the center band flat in phase characteristic in the transmission band and transmitting the information signal at the center band. CONSTITUTION:An audio signal from a telephone set 1 is applied to a hybrid circuit 3 via a band block filter 2 in voice of e.g., 300-1,000Hz and 2.5- 3.4kHz. On the other hand, the information signal having the frequency component of 1.1-2.3kHz reaches the circuit 3 via a BPF8 from a transmission section of an information signal transmission/reception device 7, synthesized with the audio signal, branched at the hybrid circuit 4 and transmitted from a terminal 5. When the synthesis signal between the audio and information signals is received from a terminal 6, it reaches the circuits 4, 3 and branched, and the audio signal is applied to a telephone set 1 via the filter 2. The information signal is applied to the reception section of the device 7 via the BPF8. Thus, while keeping the naturality of audio signal, articulation and quality of information, the simultaneous transmission of voice and information can be made with less occupied band of electromagnetic waves.

Title: Thin form light box
Inventor: MOROHASHI HISAO
IPC: F21V9/40
Filed: 1990-06-26
Abstract: PURPOSE:To provide a light surface illuminated and construction in light weight, prevent cost-up even with a minor lot, facilitate assembly, and eliminate obstruction for the producibility by introducing a specific relationship between the width of the illuminated surface and the number of light sources, and arranging the distance from the edge of the illuminated surface to the light sources so as to be no more than a specified value. CONSTITUTION:Each light source 5 is so arranged as within 20mm of the edge of the surface to be illuminated 3, even in the condition that L/2N>20, where L is the width of the illuminated surface 3 in millimeters and N is the number of light sources 5, i.e., even though the width of illuminated surface 3 per light source is larger than 40mm. Accordingly, even when ununiform reflex pattern positions on a lighting curtain 9 are out of matching with the light sources 5, unevenness in the brightness is not perceived as light unevenness due to optical illusion because the unevenness in brightness appearing on the illuminated surface in the neighborhood of the light sources 5 will also lie within 20mm of the edge of the illuminated surface 3. This arrangement, where no light guide member is used, permits lightweight construction and light surface illuminated, and also allows preventing cost-up even with a minor lot. Further because no light unevenness is perceived, no particular accuracy is required for assembly, and the producibility will not be obstructed when assembly is carried out.

IPC: H01L21/76
Filed: 1983-09-13
Abstract: PURPOSE:To obtain a semiconductor device which has a thick silicon oxidized film for isolating between elements to be flattened on the surface and stabilized in the element characteristics without producing crystal defect in the primary metal nor causing the contamination of heavy metal by enabling to employ plasma etching capable of increasing the selecting ratio of etching. CONSTITUTION:A thin silicon oxidized film 2, the first silicon nitrided film 3, a thin silicon oxidized film 2' and the second silicon nitrided film 5 are formed on a silicon substrate 1. Then, a positive type photoresist film 7 is covered on the overall surface and exposed. At this time, the quantity of light becomes very small as compared with other photoresist portion at the photoresist portion under an overhung, and the film 7 remains only under the overhung in the next step of developing. Then, when the film 5 is removwd by plasma etching with CF4 as main content, the photoresist 7 becomes a mask, and the film 5 on the side wall is not removed. Further, since the plasma etching can increase the etching selecting ratio larger than an RIE, the primary silicon substrate 1 is not exposed, and the damage can be minimized. Since an external electrode system can be employed in the plasma etching, the contamination of the heavy metal can be prevented.
