Title: Digital data modulator/demodulator
Inventor: OTANI MASAHITO
IPC: G11B20/10
Filed: 1988-06-22
Abstract: PURPOSE:To reduce a data error rate at the time of reproducing without adding hardware by recording a reference signal preceding an input data, and correcting demodulating data in accordance with the peak value of the reference signal. CONSTITUTION:When a start/stop detecting part 5 detects the start of recording, a control part 6 sends a reference signal to a digital modulating part 2, activates a D/A-converting part 3, etc., records the reference signal and therefore, the input data are converted and recorded. At the time of reproducing, the control part 6 reads the peak vale of the reference signal read first with an A/D converter 8 and sets the table data in which the value equivalent to the level of the center value of the reference value. Since demodulating and outputting are executed by the table data in accordance with the reading value, the data at the time of reproducing are corrected and thus, correct digital data can be obtained.

Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To improve a reliability of a pump function by providing a plurality of guide rib-like pieces on a discharge passage inner wall face of an injection head so that a ball valve forming a discharge valve moves vertically along a center of the discharge passage. SOLUTION: When an injection head 8 is vertically moved by pushingly operating it in the case of using a fluid hollow container, since an inside of a cylinder 5 becomes negative in pressure, a valve plate 4c rises and a suction valve opens, a liquid in the container is introduced into the cylinder 5. When successively an injection head 8 is pushed down, since the inside of the cylinder 5 becomes high in pressure, and the valve plate 4c descends to close the sunction valve, the solution in the cylinder 5 pushes up a ball valve 6b to open a discharge valve, and is injected from an injection nozzle 7 through a discharge passage of a stem 6 and the injection head 8.  In this case, since a rib 8b is provided to a discharge passage inner wall of the injection head 8 so that the ball valve 6b moves vertically in a central part of the discharge passage, even for a highly viscous liquid or the like the ball valve 6b is prevented from sticking to the discharge passage wall face.
