Abstract: This invention relates to methods and apparatus for extracting data of a channel from and for inserting low speed input data into a channel of time division bit multiplex. An optical data transmission system is used for distribution of video signals or information services. A variable frequency divider generates a timing signal by frequency dividing a clock signal by N. The resulting timing signal is phase shifted by M clock periods by inserting one cycle of 1/(N+M) frequency dividing in accordance with a synchronous command signal. With the timing signal, data of a channel is extracted from the time division multiplexed data of N channels by an extracting circuit, such as a D-type flip-flop. With a synchronous signal generated from the timing signal having the same pulse width of the multiplexed data, a low speed input data is inserted into a channel of the multiplexed data of N channels by a selector.

Abstract: A horizontal synchronizing signal Hs and a vertical synchronizing signal Vs are converted to digital data, respectively, by corresponding frequency-to-voltage conversion circuits 10 and 20 and AD conversion circuits 30 and 40. These digital data are compared with regulation values corresponding to the operation frequencies of a CRT display 2000 stored in the regulation value memory 90 by a frequency decision circuit 50 so that abnormality of frequency of the horizontal synchronizing signal and vertical synchronizing signal is decided. At an abnormal time, the state indication data corresponding to the abnormal state are read out from the state indication data memory 70. The display control circuit 60 constitutes a new video signal based on the state indication data and supplies the new signal to the CRT display in place of the video signal from the computer 1000 through the switch 80.

Abstract: A process for improving the solubility of hydrophobic amino acids in which hot saturated aqueous solutions of at least two different amino acids are first combined. A first step includes making a hot saturated aqueous solution of a first and hydrophobic amino acid having a low solubility in water. A second step includes making a hot saturated aqueous solution of a second and hydrophilic amino acid having a high solubility in water. Then the two hot saturated aqueous solutions are mixed to prepare a combined hot solution mixture, and dried. The resulting product is an amino acid food supplement which is blended into animal feed. The preferred amino acids are tryptophan and lysine, when the animal is a domestic farm animal. A preferred ratio is where the concentration of tryptophan is greater than 50 grams per liter and the concentration of lysine is greater than 300 grams per liter.

Abstract: A container including a base and an associated cover which form an enclosure for blister packs, pills, medication or other small articles. The container includes at least three latches located around the perimeter of the container to hold it closed. The latches can only be disengaged by applying pressure to all the latches simultaneously. In addition, the latches are spaced from each other so that two hands are required to simultaneously release all of the latches. Openings are advantageously placed near the latches to allow the user to exert inward pressure on the walls of the container, which pressure acts to disengage the latches.

Abstract: A universal radiographic/fluoroscopic "room" is constructed according to the present invention by combining a versatile group of X-ray examination system components, electrical and mechanical drive components, and sensing components, under the supervision of a flexible control system, to form a universal diagnostic medical imaging system capable of performing radiographic, fluoroscopic, tomographic, and stepped examinations in several different operator-selectable configurations. The operator selects any available operating mode, including auto-bucky, auto-wall, auto-table, auto-table/wall, servo-tomo, conventional stepping, stepped-digital, auto-step, and auto-step-center modes, using a a control panel. The control system automatically determines which system components are required to perform that type of examination, moves the components into operational or storage positions as required, and prepares each component for operation. The operator need not manually reconfigure the equipment.

Abstract: A telephone set is provided with a first microphone at the position close to a speaker and a signal including remaining noise is outputted from the first microphone. Background noise is outputted from a second microphone. A noise elimination circuit estimates background noise reaching the ear of a receiver based on the background noise signal, the signal including the remaining noise, and a received voice signal from a transmitter. Also, the noise elimination circuit subtracts the estimated background noise from the received voice signal to supply the resultant signal to the speaker.

Abstract: The invention provides an n-channel MOS field effect transistor with an anti-radioactivity. The transistor includes leak guard boron diffusion layers, each of which has a junction surface to an isolation oxide film. The junction surface exists up to a deeper level than a predetermined depth corresponding to a junction surface of n-type source and drain diffusion layers and a p-type silicon substrate. Such leak guard boron diffusion layer is formed by ion-implantation of boron through a gate oxide film, after a formation of the gate oxide film. Such leak guard boron diffusion layers have a higher impurity concentration. The existence of the leak guard boron diffusion layers suppresses a leak to be generated by radiation damages of silicon oxide film such as the gate oxide film and the isolation oxide film.

In the surface of the photodiode, a rectangular recess is selectively formed toward inside of the N-type epitaxial layer. On the side face of the recess, a silicon oxide layer is formed. In the region surrounded by the silicon oxide layer, a photo absorbing layer and so forth is formed. On the other hand, in an optical waveguide, a LOCOS oxide layer is formed toward inside from the surface of the N-type epitaxial layer. The N-type epitaxial layer is sandwiched between the LOCOS oxide layer and the N.sup.+ type buried layer. The refraction indexes of the LOCOS oxide layer and the N.sup.+ type buried layer are smaller than that of the N-type epitaxial layer.
