Title: Optical demultiplexer
Inventor: FUJII YOJI
IPC: G02B27/28
Filed: 1988-02-12
Abstract: PURPOSE:To obtain a multi-wavelength optical demultiplexer which is small in size and less in loss without using any precise working parts by turning the polarizing direction of linearly polarized light to a prescribed direction in accordance with the wavelength of wavelength-multiplexed light and demultiplexing the linearly polarized light by using a biaxial optical crystal. CONSTITUTION:Wavelength-multiplexed light becomes linearly polarized light having the same polarizing direction after passing through a polarizer 5. When each of the linearly-polarized constituent light is passed through an optical rotator 6, the polarizing direction of each constituent light is turned by an angle corresponding to the wavelength. When each constituent light which is turned by the angle corresponding to the wavelength is passed through a biaxial optical crystal 7, each light is emitted from a different position depending upon the polarizing direction, and thus, the wavelength-multiplexed light is separated into each constituent light. Therefore, a multi-wavelength optical demultiplexer which is small in size and less in loss can be obtained without using any precise working parts.

Title: Picture transmission equipment
Inventor: SATO KOJI
IPC: H04N19/46
Filed: 1992-01-20
Abstract: PURPOSE:To reduce the data volume of a transmission picture to shorten the transmission time and to economize the file capacity by using a Huffman code encoding table most suitable for the brightness of a picture to be compressed and using plural inverse Huffman code encoding tables in the case of expansion. CONSTITUTION:When an input picture is transmitted, the picture is converted into digital data by an A/D converter 1, and this data is temporarily stored in a first memory part 2. Data in the memory part 2 is subjected to DCT operation and the processing of run length or the like by a compressing part 3, and compressed data is encoded to a Huffman code. At this time, converted digital data is inputted to a detecting part 9, and its average value is compared with a prescribed reference value. Since the reference value is so set that the degree of brightness or darkness of the input picture can be detected, a corresponding detection signal is outputted from the detecting part 9. Thus, one of Huffman code encoding tables 10, 11, and 12 is selected by a control part 13 to obtain the minimum data volume.

Title: Dust precipitating electrode
Inventor: NAKAJIMA HIRAYUKI
IPC: B03C3/45
Filed: 1990-02-08
Abstract: PURPOSE:To decrease the frequencies of washing and exchanging of dust precipitating electrodes for the user of an electrostatic precipitator by forming the inter-electrode distance between the dust precipitating electrode plates and counter electrode plates larger on the suction side where air flows in than on the side where the air is discharged. CONSTITUTION:The inter-electrode distance between the dust precipitating electrode plates 2 and the counter electrode plates 1 is formed larger on the suction side where the air flows in than on the side where the air is discharged. Namely, the dust precipitating efficiency on the suction side part where the air contg. electrified dust flows in is lowered and the dust precipitating efficiency of the discharge side part is enhanced and, therefore, the concentrated precipitation of the dust in the suction side part is relieved and the dust is dispersed to the dust precipitating electrode plates. The dust is thus eventually adsorbed. The shorting between the electrodes by the local dust sticking is prevented in this way and the period of using the dust precipitating electrodes is prolonged and the laboriousness of the operations to wash and exchange the dust precipitating electrodes on the user side is lessened.
