Title: File management system
Inventor: AOKI RYUICHI
IPC: G06F12/00
Filed: 1992-02-12
Abstract: PURPOSE:To access data without paying attention to inhibit control by reading out the latest information to output it to a display means at the time when information referred to at present is not the latest information. CONSTITUTION:A signal is outputted from a timer at intervals of a prescribed time to interrupt a file 10 by an interrupt handling part, and only data other than the latest data are read out from a log table 13, thereby requesting the switching for reference to the latest data. The length of the log table at the time of preceding reference and the present length of the log table are compared with each other to discriminate whether the state referred to at present is the latest state or not, and it is judged that it is not the latest state because of update if the present length is longer. When it is judged that it is not the latest state, only updated data other than the latest data are read out from the file 10 and are displayed through the interrupt handling part. Consequently, the latest data in the range of the set interval is automatically displayed.

Filed: 1983-02-17
Abstract: PURPOSE:To give high-speed response property as well as low dark currents and a high multiplication factor by introducing an InGaAsP buffer layer between an InGaAs optical absorption layer and an InP multiplication layer. CONSTITUTION:An N type In0.53Ga0.47As optical absorption layer 22, an InGaAsP buffer layer 23, an InGaAsP buffer layer 24 and an N type InP multiplication layer 25 are grown on an N<+> type InP substrate 21, thus forming an avalanche- photodiode. In the photodiode, incident beams are absorbed by the layer 22, and electron-hole pairs are generated, but holes in the pairs are injected to the layer 25 through hetero interfaces 29, 28, 27. When the forbidden band width Eg of the layers 23, 24 is each made to be 0.85eV and 1.0eV, Eg of InP and In0.23Ga0.47As is each 1.35eV and 0.75eV. Consequently, the magnitude of barriers in the interfaces 27-29 is each 0.1eV, 0.15eV and 0.35eV, and the probability of which holes are accumulated in each barrier is reduced. Accordingly, the titled photodiode can display practically sufficient high-speed response property.

Title: Magnetic recording and reproducing device
Inventor: YAMASHITA TAKEO
IPC: G11B5/03
Filed: 1985-02-15
Abstract: PURPOSE:To improve the frequency characteristic of an output signal reproduced from a high density recording medium without being affected adversely by spacing by impressing a bias magnetic field on the recording medium so as to invert magnetization and reproducing recording information. CONSTITUTION:When information is reproduced from the recording medium 1, a bias current is flowed in a magnetic head 2 from a bias generating part 6 so as to apply a bias magnetic field to the medium after recording and reproducing switching part 3 is set to the side of reproduction. When the medium 1 receives the bias magnetic field and the magnetized state is at a +Br0 point, a voltage (reproduction signal) is not induced on the head 2. Meanwhile the voltage is induced in the head 2 when said state is at a -Br1 point, and the voltage is amplified 5 and becomes reproduction information. Thus the titled device will not be affected adversely by spacing, and accordingly the frequency characteristic of the output signal reproduced from the high density recording medium can be improved.
