Title: Voltage generating circuit for controlling oscillator
Inventor: SUGIYAMA KAZUO
IPC: H03B5/02
Filed: 1985-05-07
Abstract: PURPOSE:To obtain a control voltage having a characteristic in matching with the characteristic of an oscillator and to change the characteristic according to the oscillator by constituting a control voltage generating circuit with a series circuit of many voltage dividing resistors, variable resistors for slope change and upper/lower limit adjustment and changeover switches for said circuits. CONSTITUTION:A control voltage generating circuit 35 in a channel selection operating section 21 consists of voltage division resistors R1-R11, variable resistors 38,39 for upper/lower adjustment, a slope change variable resistor 40, and a changeover switch 44 for the voltage division resistors, and further provided with an odd number/even number switching circuit 46 and an adder circuit 51. Thus, in changing over the switch 44 and supplying a control voltage to an oscillator 26, even when the oscillator 26 has a characteristic of chevron shape with respect to an input voltage and the oscillation frequency, since a slope change resistor 40 is connected as shown in figure, the generating circuit 35 can give an oscillator control voltage changing in the relation of a reversed chevron shape to the oscillator 26 according to the switching state of the switch 44. Even when the same resistance is used for the voltage division resistors, a variable resistor is used for the slope change resistor 40 and the voltage of a folding point in the inverse chevron shape characteristic and its higher or lower slope are changed optionally using the variable resistors 38, 39.

The arm 58a is shrunk by an arm stretching motor and the tip of the arm 58a is caused to face a work base 11 by a rotary motor M1. When the top board T is taken out of the top board housing rack 12, the tip of the arm 58a and the top board housing rack 12 are placed opposite each other by the rotary motor M1 and the arm 58a is raised up to a height obtained by subtracting a work up/down amount from a highest stage by the up/down motor M2. At this time, a controller raises the arm 58a up to a specified height by the up/ down motor M2 and stretches the arm 58a by the arm stretching motor. Thus, the top board T is transferred to the work base.

Title: Method and device for arithmetic processing for floating point binary number
Inventor: URANO YOSHINORI
IPC: G06F7/76
Filed: 1993-04-23
Abstract: PURPOSE:To accelerate the denormalization of a floating point binary number. CONSTITUTION:Post-processing is performed to a mantissa M and an exponent E of the floating point binary numbers as the result of subtraction, for example, and a mantissa (m) and an exponent (e) are obtained as the result. Therefore, an output (E-1) of a decrementer 201 and an output (digit drop amount LSA of the mantissa) of a preceding '1' detection circuit 20 are inputted to a minimum value selection circuit 203. In the case of (E-1)<LSA (namely when denormalization is required,) the minimum value selection circuit 203 sets shift amount SH to the (E-1) and turns a level discrimination signal CR to '1.' In the case of (E-1)>=LSA (namely when normalization is required,) the SH is set to the LSA and the CR is turned to '0'. A left shirter 204 outputs a value performing the left shift processing of the shift amount SH to the mantissa M as the mantissa (m) of the result. A selection circuit 207 outputs '0' in the case of CR=1, and outputs the output (E-LSA) of a subtraction circuit 206 as the exponent (e) of the result in the case of CR=0.
