CONSTITUTION: In this external storage device to which the compressed data expansion mechanism (LSI) is mounted, a ROM data output mechanism 5 which is the internal mechanism of the data expansion LSI 3 is a mechanism for reading the non-compressed data at random and an expansion/transfer part 4 for the compressed data is the mechanism for expanding the compressed data and transferring them to a CPU 7 after expansion. By making the compressed data expansion part and expanded data transfer part of the expansion/ transfer part 4 for the compressed data parallelly perform processings, continuous expansion/transfer are made possible and a continuous read rate is made equal to the read rate of the non-compressed data. Even when the data are stored in a ROM 2 in the form of a small data amount, that is a compressed data form, no hindrance by the read rate is present. Thus, the ROM 2 is effectively utilized and the ROM 2 is not excessively increased.

Filed: 1981-10-27
Abstract: PURPOSE:To control an EGR amount properly by controlling a negative pressure actuator by feedback in accordance with the output signal from an oxygen density detector provided in an exhaust passage for performing combustion during operation near the optimum air-fuel ratio. CONSTITUTION:An output signal of an oxygen density sensor 10 provided in an exhaust pipe 4 is transmitted to a control circuit 14. When the value of this output current is higher than the value of the current at a previously set air- fuel ratio, ports 15a and 15b of a three-way valve 15 are connected through, and a high negative pressure from a vacuum pump 13 is directly introduced into a pressure chamber 9b for increasing the EGR amount.

Consequently, the actuator 9 receives a negative pressure given by a negative pressure control valve 11, and opens or closes an EGR valve 7 in accordance with the opening of a regulation lever 5a of a fuel injection pump.

Abstract: PURPOSE:To obtain the stable lateral mode in the light emitting device wherein a light confining layer is embeded in a clad layer which holds an active layer in- between with a stripe region being remained, by controlling the diffusion of lateral carriers by the P-N junctions formed in an active layer. CONSTITUTION:On an N type InP substrate 1, are layered an N type InP clad 2, a nonadded InGaAsP active layer 3, a P type InP clad 4, an N type InGaAsP light confining layer 5. Then, by using an SiO2 mask, the layer 5 is etched 5A in a stripe shape with a blended liquid of H2O2-H2SO4-H2O. Thereafter, P type InP clad layer 6 and P type InGaAsP 7 are layered. As impurities, Te is used for the layers 2 and 4, Cd for the layer 5, and a large amount of Zn for the layers 6 and 7. Therefore, only the part 3A of the active layer is transformed into P type by Zn and the P-N junction is formed between the part 3B and said part 3A. An electrode 8 is made of Au-Zn and an electrode 9 is made of Au-Ge-Ni.

Abstract: PURPOSE:To attain a circuit with high general-purpose application by providing a frame length setting means jumping optionally a change timing of a load address corresponding to a frame length of an input data string, and applying address control to its output. CONSTITUTION:A frame length counter 7 counts a bit number of a frame length based on a frame identification pulse 13, outputs a frame length designation signal 23 and inputs it to an address control circuit 8.

Filed: 1993-07-12
Abstract: PURPOSE:To measure concentration of a fluid without being influenced by the adhesion of a suspended material or bubbles in the fluid by operating the concentration of the fluid by use of a true phase delay obtained by an operating means. CONSTITUTION:A true phase delay theta2 is corrected through a predetermined process with software at a phase difference correcting circuit 41 to obtain a phase difference DELTAtheta. The phase difference is sent to a signal converting circuit 37. When a time differential value of theta2, i.e., dtheta2/dt is positive and the phase difference becomes not smaller than that at the first rotation and the apparent phase difference is theta'2 (0 deg.<=theta'2<=360 deg.) when it exceeds 360 deg., the predetermined process by software is conducted according to theta2=theta'2+nX360 deg. (n: 0 or 1 or larger integer). When a time differential value of the apparent phase difference theta'2 at the (n)th rotation, that is, dtheta'2/dt is negative and it is not larger than 0 deg., the process according to theta2=theta'2+(n-1)X360 deg. is carried out to obtain the true phase delay theta2. The circuit 37 when receiving the phase difference signal DELTAthetaobtains the concentration of a to-be-measured fluid based on a calibration curve which preliminarily determines the relationship between the phase difference and concentration.
