Title: Bit synchronization circuit
Inventor: YASUKAWA MASANAGA
IPC: H04L7/02
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a bit synchronization circuit without needing a large and complicated control circuit, an analog device, etc., by setting the clock that has its changing point at a time having a phase different by about 180 degrees from the time of the changing point of the data on an input terminal as its own device clock that is supplied to a decision circuit. SOLUTION: The data inputted to a data waveform shaping circuit 1 are shaped into the data and the inverted data, and the shaped input data are branched out into two data. One of both branched data is inputted to a data conversion point detection circuit 2. The circuit 2 produces a pulse having the delay value width at a position that is coincident with a data conversion point in order to secure an exclusive OR (EXOR) between the data and the data delay component. At the same time, the clock that is inputted to a system is branched out into two clocks. One of both clocks is converted into an anti- phase component via an inverted buffer 74, and this converted component is transmitted through the delay buffers 70 and 71 to secure a phase difference. Then every anti-phase component is inputted to a clock rise detection circuit 3.

Title: Magnetic tape storage device
Inventor: WADA TOSHIYUKI
IPC: G11B5/187
Filed: 1988-08-04
Abstract: PURPOSE:To suppress the surface oscillation of a tape and to attain the informa tion storage of high density by arranging a dynamic pressure pad formed a dynamic pressure generating groove to a magnetic head and the surface, on which a magnetic tape is traveled, of the magnetic head with facing to the magnetic head. CONSTITUTION:A magnetic tape 2 passes a gap between a magnetic head 1 and a dynamic pressure pad 3 through guide rollers 5a and 5b and travels like an arrow in the direction of a capstan 4b. By dynamic pressure which is generated between the head 1 and tape 2 with the traveling of the tape, the gap of sub-micron is formed on the land surface of the head 1. A dynamic pressure generating groove 10 is formed in the tape 2 side on the dynamic pressure pad. Thus, the dynamic pressure, for which pressure goes to be a maximum near the center of the tape 2 in a width-wise direction by the travel ing of the tape 2, is generated between the tape 2 and pad 3. By the force of this dynamic pressure, the surface oscillation is suppressed for the tape 2 and the recording of the high density can be executed.

IPC: F23D11/08
Filed: 1981-12-06
Abstract: PURPOSE:To enable a sufficient evaporizing combustion even if the height of an entire  burner unit is made thin by a method wherein the combustion oil is atomized into a  combustion cylinder through each of the splashing parts arranged at a plate-like evaporizing inner cylinder and an injection gas branch cylinder which is integrally rotated  at an outer circumference of the inner cylinder. CONSTITUTION:Upon combustion, at first, a plate-like evaporizing inner cylinder 5 and  a humidifying outer cylinder 6 are rotated at a high speed through a rotary shaft 4,  and at the same time, the combustion air is blown from the air passage 3 to mixture  gas passage 11 and injection passage 10, and then oil is sent from an oil feeding pipe  22 to an oil defuser 20.

The oil is injected into a combustion cylinder 1 through  a splashing part 15 and ignited through a spark plug 23. When a temperature in the  humidifying gas passage 11 rises due to combustion flame, the combustion oil in the  plate-like evaporizing inner cylinder 5 is evaporated and gasified during its flow, and  then the gasified oil is mixed with the combustion air and injected from main injection  flame passage 17, and finally injected from sub-injection flame passage 18.
