Title: Optical reception circuit
Inventor: MINAE YASUO
IPC: H04B10/60
Filed: 1985-08-12
Abstract: PURPOSE:To eliminate only a relaxation oscillation while keeping a rapid leading waveform by inserting a relaxation oscillation frequency removing filter to an optical reception circuit receiving an optical signal converting the signal into an electric signal. CONSTITUTION:An inputted electric signal 2 is converted into an optical signal and sent in an optical fiber 4. The optical signal sent through the optical fiber 4 is subjected to photoelectric conversion by a photodetector 5 and amplified by a preamplifier 6 and an amplifier 7. Since the waveform deterioration due to the relaxation oscillation of a semiconductor laser is remarkable while keeping the electric signal, the relaxation oscillation frequency removing filter 8 is inserted to reject only the relaxation oscillation. Further, the signal is amplified by an amplifier 9 to a prescribed level to obtain an output electric signal 10 with excellent waveform. A coaxial cable 12 is branched on the way of a coaxial cable 11 connecting the amplifiers 7, 9 a termination 13 is opened to set the length of the cable 12 to 1/4 of the guide wavelength of the relaxation oscillation frequency fro thereby realizing a steep band stop filter.

IPC: G11B33/00
Filed: 1985-08-12
Abstract: PURPOSE:To simplify the function of a magnetic recording/reproducing device and to prevent the reservation of a timer with an unpresent channel, by securing a unified mechanism with a remote control transmitter for mutual use of a common function and providing a remote control receiving function to the main body receiving side. CONSTITUTION:A remote control unit contains a display means for timer reservation data, an input means, a storage means, a means to convert the data into the infrared-ray remote control signals and a means to control a normal operating function and operations for timer reservation. While the main body side includes a means to receive and decode the timer reservation data, a means to set the limitation of time to receive the first data through the final data, a means to check the error of the received data and a means to display the result of said check. Then the reservation data are transmitted all at one by means of a remote control transmission function after the reservation is set. While the propriety of the received data and the transfer errors are checked at the main body side. Here a function is added to display those errors if detected. It is possible for a transmission unit to transmit the same data again since the data remain at this unit even after transfer of data.

Title: Light emitting display device
Inventor: TAKEUCHI MASAHIRO
IPC: G09F9/33
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a light emitting display device and to make images distinctly visible even when these images are viewed diagonally. SOLUTION: A display 1 is formed by laminating a circuit board 21 regularly arranged with plural light emitting diodes 23, a first light shielding body 25, a bead plate 27, a second light shielding body 29 and a lens plate 31.

Title: Sampling device
Inventor: HAYASHI TAKUMI
IPC: B01D61/22
Filed: 1989-07-07
Abstract: PURPOSE:To enable appropriate adjustment and maintenance of a sample water pressure by making the upstream and downstream sides of a V-shaped flexible pipe face each other and by pressing the two sides by an engaging means having elasticity or by varying the degree of tension or bending. CONSTITUTION:A flexible pipe 10 of a pressure controller 7 is bent in the shape of V and the upstream and downstream sides of the bent part thereof are made to face each other and they are made to engage with each other by a means having elasticity, so that a distance of separation between them can be varied. Moreover, the degree of bending of the bent part is adjusted by an adjusting screw 11 of an adjuster 7, so that a sample water pressure on the primary side of a UF film filter can be adjusted to be a desired value. When dirt such as solid particles is accumulated in the bent part of the pipe 10, the pressure on the upstream side of the adjuster 7 rises, the bent part turns to straighten and the distance of separation of the pipe 10 increases. Then the solid particles and the like that are accumulated flow away and the pressure lowers. Consequently, the bending is restored to the original degree and the sample water pressure on the primary side of the UF film filter returns to an initial set value. In this way, the sample water pressure on the primary side can be adjusted and maintained properly.

IPC: H03M1/18
Filed: 1982-10-08
Abstract: PURPOSE:To make compact the dynamic range of an analog signal by controlling the amplitude of the analog signal in response to the level of a sample value of a digital signal formed by quantizing the analog signal. CONSTITUTION:The inputted analog signal X is led to a gain control circuit 11, where the signal is amplified by a gain G set in response to a gain control signal Y2 and outputted. This outputted analog signal GX is inputted to a coder (A/D converter) 12 and outputted after quantized. This quantized signal, i.e., a digital signal X0 is recorded and reproduced in a digital signal or processed for signal. Further, the said signal X0 is led to an amplitude detecting circuit 13, where the said signal Y2 is produced. The circuit 13 receives the gain control signal Y2 in response to the amplitude of Y1 so as to provide a small gain when the amplitude of the value Y1 of the signal X0 is large and to provide a large gain when the amplitude of the value Y1 is small. Thus, the dynamic range of the analog signal is made compact between the input and output of the circuit 11.
