Title: Direct sequence digital diffusion spectrum modulator/demodulator
Inventor: FURANCHIESUKO MARUCHINIINO
IPC: H04L27/00
Filed: 1988-06-27
Abstract: PURPOSE: To realize the compact modulator-demodulator at a low cost with low power consumption using widely software algorithm by realizing a basic function with a microprocessor architecture through the digital technology. CONSTITUTION: A transmission section 1 is made up of modules 3-5. The module 3 (BB-TX) has a function of converting an input data string generated from an external signal source into a signal string to be sent and the module 4 applies digital BPSK modulation to the signal string generated by the BB-TX. The module 5 shifts a frequency of a signal from a carrier frequency into a standard intermediate frequency. A reception section 2 is made up of modules 8-6, and the module 8 (RX CONV) shifts a frequency of a standard intermediate frequency signal into a carrier frequency. The module 7 demodulates a signal received by the BPSK standard system and the carrier is extracted by using additional information obtained from a collector of the BB-RX module. Then the module 6 (BB-RX) extracts a data string generated in a transmission process from the demodulated signal string.  Thus, the flexible MODEM with low power consumption at a low cost is obtained.

At a curved portion C of the cover 1, which has a tight curvature, is formed a folding portion 6 where the layered plate is folded in two in the bending direction. The bend in the curved portion C, which has a tight curvature, is mainly formed by the drawing of the laminate formed flat plates in the forming of the folded portion 6. There is therefore little elongation of the laminate formed flat plates when the curved portion C is formed and the curved portion C is easily able to be formed in the desired shape.

Title: Projector device
Inventor: KIMURA SHUNSUKE
IPC: H04N5/74
Filed: 1991-06-28
Abstract: PURPOSE:To eliminate the image plane deviation of the whole projection lens by utilizing refractive index variations of a positive lens, composed of a uniform- thickness lens and liquid, and a field flattener lens, composed of a shell lens and cooling liquid, with temperature. CONSTITUTION:The temperature of the cooling liquid 2rises by the heat generation of the surface of a cathod tube a after a lapse of a sufficient time after projection is started, and the shell lens 3 rises in temperature by the excellent heat conduction of the cooling liquid 2. A radiator 7 rises in temperature since it radiates the heat of the cooling liquid 2 to the outside and the uniform- thickness lenses 4 and 6 and liquid 5 also rise in temperature. Consequently, the refractive indexes of the cooling liquid 2, shell lens 3, uniform-thickness lens 4, liquid 5, and uniform-thickness lens 6 decrease respectively. The negative power of the negative lens composed of the cooling liquid 2 and shell lens 3 decreases and the positive power of the positive lens composed of the uniform- thickness lens 4, liquid 5, and uniform-thickness lens 6 also decreases. Therefore, there is no variation in the focal length of the whole projection lens.
