Title: Sector buffer control system
Inventor: HATSUTORI NAOTATSU
IPC: G06F3/06
Filed: 1987-09-16
Abstract: PURPOSE:To shorten data transfer time without increasing the amount of circuits by simultaneously performing data transfer processing between a disk device and a sector buffer and that between the sector buffer and a system bus. CONSTITUTION:When a FF 7 is set to logical '1' to command transfer to and from a system buffer 12, data on a disk 10 is stored in a sector buffer 1 designated by a buffer switching circuit 8 and is counted. A flag 5 is set to logical '1' to interrupt transfer when the transfer of one-sector components of data is terminated, and the transfer is restarted when the buffer 1 is switched to the buffer 2 by the circuit 8. Simultaneously, data is transferred from the buffer 1 to the bus 12 by the FF 7 and the flag 5; and when the flag 5 is set to logical '0', data is transferred from the buffer 2 to the bus 12. Thus, the transfer between the disk and the buffer and that between the buffer and the system bus are simultaneously performed to shorten the processing time without increasing the quantity of circuits.

Title: Method for measuring cut-off wavelength of single mode optical fiber
Inventor: MIYAMOTO SUEHIRO
IPC: G01M11/02
Filed: 1988-09-19
Abstract: PURPOSE:To measure a cut-off wavelength by arranging a polarizer to at least one of the input and output terminals of a single mode optical fiber. CONSTITUTION:A polarizer 10 is provided between a monochrometer 3 and the input terminal of an optical fiber 1. A fundamental mode LP01 and a tertiary mode LP02 are linear polarization and, in a secondary mode LP11, degeneracy is released in the vicinity of a cut-off wavelength and said mode LP11 is not linear polarization. The excitation of the secondary mode is removed by inserting the plarizer 10 and the cut-off wavelength of the tertiary mode to the fundamental mode is measured. A wavelength of difference is drawn using a waveform (b) in a case inserting no polarizer 10 and a wavelength (a) in a case inserting the polarizer 10 to know the cut-off wavelength lambdac only of the secondary mode. By this constitution, the effect of other modes is removed to make it possible to perform measurement with high accuracy. When a detector is also provided on an emitting side in parallel to an incident side, the extinction ratio of the fundamental mode and the tertiary mode can be increased.

Title: Constant voltage source circuit
Inventor: KARAKI TOSHIRO
IPC: G05F3/24
Filed: 1992-08-08
Abstract: PURPOSE:To make a constant voltage source circuit in which temperature dependency is eliminated from output voltage. CONSTITUTION:A PMOS transistor 42 is provided between a constant current source 40 composed of a resistor 41 and a constant voltage source 43 composed by serially connecting plural NMOS transistors 44. The gate of the PMOS transistor is connected with an output VOUT. When the output voltage of the constant voltage source 43 rises due to temperature changes, the current flowing in the constant voltage source 43 decreases because the ON resistance of the PMOS transistor 42 rises with this. Thus, as the output voltage of the constant voltage source 43 is pressed in the lowering direction, the output of constant voltage to the VOUT is always held constant regardless of temperature changes.
