摘要： PURPOSE:To reduce a hard quantity in a master-slave type register, which can hold plural data by using a means to make a master part common to respective fields. CONSTITUTION:A continuous clock is supplied to phi, and the clocks which have the same period of H as phi, and have periods double as log as phi, are supplied to phi1, phi2, by dislocating their phases. Since as for data D1 just before time T1 fetched through a transfer gate TG1 both phi, phi1 go to H, and phi2 go to L at the time T1, the transfer gates TGs 2, 3, 6 become conductive, and the TGs 1, 4, 5 become non-conductive, and a data D1, fetched through a transfer gate TG1, is outputted to an output Q1 through inverters 9, 10. During the time T2, since all phi, phi1, phi2 are L, both a first and a second slave parts come to closed loops, and the values of Q1, Q2 are held. At the time T3, when phi goes to H, phi1 goes to L, and phi2 goes to H, the TGs 2, 4, 5 become conductive, and the TGs 1, 3, 6 become non-conductive. Accordingly, Q1 holds the data D1, and the last data D2 fetched during the T2 period is outputted to the output Q2. At the time T4, the data similar to the T2 is held and hereafter, as for T5-T8, it is a similar operation, excepting that the data are different.

摘要： PURPOSE:To make a circuit small-sized and economical by providing a means which suppresses the word length of an exponent part operating circuit to a required minimum bit width to prevent the malfunction even at the time of overflow and underflow of the exponent part. CONSTITUTION:Exponent parts EA and EB of a multiplier A and a multiplicand B are inputted to an exponent part adding circuit 31 to perform the addition processing. If underflow is detected in the addition result by a detecting circuit 32, the detection signal is outputted as a carry signal to a subtracting circuit 40. The subtracting circuit 40 adds +1 after adding -1 to input data and outputs data of the adding circuit 31 as the result as it is. Therefore, two inputs of a selecting circuit 53 are output data of the adding circuit 31 together and are equal to each other even if underflow occurs in the exponent part. Consequently, the malfunction does not occur though the normalization processing is performed in the mantissa part.

摘要： PURPOSE:To easily and exactly execute the inhibition of write to a memory by a program instruction, by inhibiting the write which is executed by one instruction together with read-out, when a offset value for a write is a specific value. CONSTITUTION:Offset data A0-A5 from an instruction register 1 and data for index from an index register 4 are processed by an adding circuit 5 and address for a built-in RAM access is formed. When the offset data from this register 1 becomes a specific value, and each bit A0-A5 of the offset data becomes '1', the output S of a NAND gate 3 becomes L, and becomes a write inhibiting signal. In this way, the inhibition of write can be executed easily and exactly by a program instruction without providing a hardware such as a write inhibiting circuit, etc.

摘要： PURPOSE:To reduce an operating time by applying updating operation sequentially by the number of times obtained by the 3rd step sequentially and using an updated dividend obtained finally as a quotient to reduce the number of arithmetic steps. CONSTITUTION:In the 3rd step, based on the data word length of a mantissa part of a divider (B0) or a dividend (A0), the number of times (m) of the updating operation executed in the next 4th step. In the 4th step, m-time of updating operation is applied sequentially to the dividend (A0'') revised by the 2nd step and the updated dividend (Am=Am-1.Sm-1+Am-1) obtained finally is used as a quotient. Among the m-time updating operation executed in the 4th step, the 1st updating operation a product (A0''S0) obtained by multiplying the (A0'') updated at the 2nd step by the initial value (S0) of the convergent coefficient, and the result is added with the dividend (A0''), then the sum (A0''S0+A0'') is obtained, then it is used as the 1st updated dividend. Thus, the division processing is quickened by the remarkable reduction in the number of arithmetic steps and the further reduction of the operating time.

摘要： PURPOSE:To improve the converting efficiency from pressure to electrical signal by providing a concavo-convex shaped soft part at the pressure receiving part. CONSTITUTION:Many light sources 2 are embedded and arranged in e.g. matrix state pattern to a light source base plate 1, and photodetectors 4 are provided with equal pitches as the sources 2 on or in a sensor base plate 3. The lights emitted from the sources 2 are passed through light passing parts 5 of the plate 3 and the soft part 6, reflected by a light reflecting film 8, made incident on the photodetectors 4, and converted to electrical signal by photoelectric conversion. When pressure is applied by a material 10 from an arrow A direction, protruded parts 7 in the range are compressed and deformed.

摘要： PURPOSE:To embed a photoconductor into a cylindrical rotary body so that the photoconductor itself can not be rocked, in the equipment for scanning a light path by means of rotation or reciprocal motion of the photoconductor arranged in one line. CONSTITUTION:When the pattern generator 7 inputs, for instance, code of the first line of an alphabetic character B to the selecting circuit 6, the selecting circuit selects the light sources 5a-5g, which are lighted. Light beams of the light sources are made incident onto the ends 4a-4g of the optical fibers 3 which are arranged in the circumferential direction on the external surface of the cylindrical rotary body 1, emerge out of the ends 3a-3g, and are displayed on the screen 12. Subsequently, when the cylindrical rotary body 1 is rated in the direction as indicated with an arrow 13, the photodetecting element 8 receives a light beam of the light emission element 9 by the passive reflector 11b, its waveform is shaped by the waveform shaper 10, and after that, a signal is sent out to the selecting circuit 6 and the pattern generator 7. When the rotary body 1 is rotated by a prescribed angle, the light sources 5b-5h correspond to the ends 4a-4g, the light sources 5b-5h to be lighted next are selected in the circuit 6, and a code of the second line is sent to the light sources 5b-5h.
