Abstract: PURPOSE:To produce a grain-oriented silicon steel sheet having a good insulated film and high magnetic flux density properties by incorporating Bi into a steel slab having a specified componental compsn. and executing decarburizing annealing under specified conditions. CONSTITUTION:A slab contg., by weight, 2.5 to 4.5% Si, S+0.405Se<=0.014% or the like, and the balance Fe is heated to <=1280 deg.C and is thereafter subjected to hot rolling. Cold rolling for >= two times in which the draft of final cold rolling is regulated to >=50% and process annealing is included is executed. Furthermore, the steel sheet is subjected to nitriding treatment in the process from decarburizing annealing to the start of secondary recrystallization in final finish annealing. Then the slab stock is incorporated with 0.002 to 0.05% Bi. The temp. in the front area in the decarburizing annealing is regulated to 800 to 880 deg.C, that of the rear area is regulated to 850 to 930 deg.C for 10 to 300sec, and the pH2O/pH2 of its atmosphere is regulated to <=0.15. The steel is moreover incorporated with Sn, Sb and Cu. In this way, stably good tertiary recrystallization can be obtd. in the wide range of decarburizing annealing temp.

Title: Oscillation circuit
Inventor: MURAYAMA AKIHIRO
IPC: H03B5/00
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To add a function for tracking an injected signal, when an self- oscillation frequency fluctuates and to provide oscillation signals of sine/cosine, which have a precise phase relation against an input signal, by injecting the input signal to the amplifier of the feedback path of an oscillator using a transconductance (gm) variable filter circuit and a node in a gm filter. SOLUTION: An injected signal Vin from a signal source, which is injected into an input terminal 4 of an oscillator 1, and the output of a gm filter 3 are inputted to an amplifier 2. The amplifier 2 amplifies a difference between the output of the gm filter 3 and the injected signal Vin or the sum of them. The output of the amplifier 3 is fed back to the input of the gm filter, and an oscillation loop is constituted. The autonomous oscillation frequency of the gm filter is decided by a control signal inputted to a frequency control terminal 5. Thus, a phase is locked, so that the signal phase of the output of the gm filter 3 becomes zero degree, namely, in-phase with respect to the injected signal Vin. Then, the oscillation output of a sine wave can be obtained from an output terminal 6.
