Abstract: PROBLEM TO BE SOLVED: To provide the MH data expansion method with a fast expansion speed for MH data. SOLUTION: Eight-bit data read from MH data are converted simultaneously into number of consecutive 0-dots by using a zerorun number detection table a 1st 8-bit read start position detection table is in use to detect a start position of reading 8-bit data next from the MH data and and then the MH data are read by 8-bit from the read start position. The read 8-bit data are converted simultaneously into number of consecutive 1-dots by using a 1-run number detection table. A 2nd 8-bit read start position detection table is used to detect a read start position again for the 8-bit data from the MH data and the MH data are read by 8 bits from the read start position and then a series of operations above is repeated.

Filed: 1982-03-17
Abstract: PURPOSE:To prevent an overcurrent drive of a photocoupler light emitting part, by driving a photocoupler with a constant current to detect the ON/OFF of the phase-controlled AC voltage. CONSTITUTION:The AC voltage of a phase-controlled OFF period is applied across a phase control element 2 in a pause period of a pause period detecting circuit 6. The AC voltage is rectified by a full-wave rectifying circuit 14 and applied to a constant current circuit 31. The circuit 31 consists of a TR32, a constant voltage diode 33 and resistances 34 and 35. The driving currents of photocupler light emitting elements 11a and 12a connected to the collector of the TR32 are decided by the values of the component elements of the circuit 31. Then the current flows to the photocoupler elements to detect a pause period of the element 2. In such a way, an overcurrent drive is prevented for a photocoupler light emitting part. This can prevent the breakdown of the element 2.

Further, their dentinal maturation is promoted after eruption and low concentration of F is fed to the dentine for a long period of time, as Ca and P concentrations in the packed fissure is kept high. Thus, the agent has effect of not only the dentinal maturation, but also recalcification of initial tooth decay and the dentinal strengthening.

Filed: 1990-02-22
Abstract: PURPOSE:To obtain a voice band dividing decoder reducing the quality degradation of a voice signal even for reproducing a signal with low reliability by providing a range information memory and a two-dimensional range information interpolation part. CONSTITUTION:A range information memory 16 stores range information and the error flag from a range information error detection and correction part 13, and a two dimensional interpolater 17 reads out the range information and the error flag from the range information memory 16. In the block of a partial band generating error, while using the range information of the adjacent partial band and the range information before and behind the block generating the error, the range information of the block generating the error is interpolated and outputted with high accuracy in a frequency base and a time base. Therefore, by synthesizing signals in the respective blocks of the respective partial bands, the frequency spectrum of the reproduced voice signal can be smoothly linked even on the frequency base or the time base. Thus, when generating the error, the quality degradation of the voice signal can be suppressed.

Filed: 1989-02-21
Abstract: PURPOSE:To realize an etching operation as a unit of an atomic layer of a semiconductor crystal by a method wherein it is controlled by a difference in an equilibrium vapor-pressure temperature whether a reaction product is evaporated or remains. CONSTITUTION:In a first process in which a reactive gas 16 is reacted with a constituent element of a compound semiconductor 11, a gas with which a gas 17 whose composition is identical to that of a reaction product 18 produced when the reactive gas 16 has been reacted with the constituent element of the compound semiconductor 11 has been mixed only in a saturated vapor-pressure amount is used as an etchant gas. As a result, an etching operation is stopped in a state that the surface of the compound semiconductor is covered with the reaction product 18. Then, in a second process, a temperature of the compound semiconductor is raised to a sufficiently high temperature; thereby, the reaction product 18 on the surface of the compound semiconductor formed in the first process is disconnected. Only one layer of an atomic layer or a molecular layer of the compound semiconductor is etched by using the first process and the second process as one cycle. Thereby, when a changeover operation of a substrate temperature is repeated, the atomic layer as a unit can be etched.
