Filed: 1988-10-31
Abstract: PURPOSE:To obtain stable searching and playing operations by making a transfer frequency characteristic broader in a searching operation mode than in a playing operation mode for a feedback means. CONSTITUTION:When a searching command is received from a keyboard 9, a control part 5a drives a selective switch 41, connects the serial circuit between a resistance R43 and a capacitor C42 in parallel to a resistance R42, and executes the searching operation mode.

Filed: 1986-11-20
Abstract: PURPOSE:To enable a semiconductor single crystal film having any required impurity concentration to be grown under control of an order of monomolecular layers, by selecting a time for adding an impurity, keeping high quality of thin-film crystals and adding the impurity to provide a required concentration. CONSTITUTION:When AsH3 and TEG are used as N-type dopant adding source gas and Si2H6 is used as additive gas. Si substitutionally enters into the Ga site of III-family to provide an N-type dopant. The AsH3 and the TEG are introduced and discharged alternately so that a monomolecular layer is grown in each cycle. In this growth process, the impurity is added once per cycle, at the time (A) of discharging AsH3, the time (B) of introducing TEG, the time (C) of discharging TEG and the time (D) of introducing AsH3. In these modes (A)-(D), a film is deposited while keeping all other conditions fixed except that the time of adding Si2H6 is varied. Thereby, it is possible to confirm from electric measurement that approximately a monomolecular layer is grown per cycle at a predetermined temperature of the substrate.

Abstract: PURPOSE:To improve operating speed by making one number of times of the operation of a barrel shifter of large-scale hardware enough for one number of times of operation processing. CONSTITUTION:In the case where quantity by which the mantissa part of a not larger number between two numbers is shifted to the right in order to make the exponent parts of these two numbers coincide with each other is 2 or larger, this processing is executed by the barrel shifter 9, and in the case where this quantity is 0 or 1, the processing is executed by the right shifter 10 of one bit. A mantissa part ALU 13 executes the operation processing necessary to these two numbers processed by the processing, and a normalizing shift number detection circuit 12 detects leftward shift quantity necessary for normalizing the mantissa part of an operated result, and the mantissa part is normalized by the barrel shifter 9 or a one bit shifter 11. Besides, the correction of the exponent part is executed by an exponent part correcting subtracter 23 in accordance with it. Thus, since the barrel shifter 9 operates only one time for one number of times of the operation, the operating speed is improved.
