Title: Static pressure supercharged diesel engine
Inventor: MAEBATAKE SHIGERU
IPC: F02B37/00
Filed: 1983-02-17
Abstract: PURPOSE:To improve a performance of an engine without deteriorating an efficiency of a blower by a method wherein a supercharger to be operated under a low load has a surplus value with a suitable surge in a low load, and a supercharger not to be operated in a low load operation has a surplus value with a suitable surge in a full load operation. CONSTITUTION:In a low load operation, one supercharger is in its non-operated condition. A broken line C indicates a surge line of one supercharger having all same specifications and a solid line C2 indicates a surge line of diffuser having different passage areas. In both superchargers, one supercharger having the surge line C2 and operating line b2 closely related to each other can improve a performance of a blower. When two superchargers are operated, a solid line bi indicates a non-operated supercharger under a low locad and a solid line b2 indicates an operating line for a supercharger to be operated under a low load. Marginal values can be attained substantially equally up to each of the surge lines c1 and c2.

Abstract: PROBLEM TO BE SOLVED: To provide a reversible boding system in which an audio signal is compression-coded with high efficiency and the coded signal is completely decoded. SOLUTION: A frequency are information generating section A applies band split to a digital audio signal and encodes the resulting signal by using the quantized sample value though bit distribution depending on an information amount based on the energy obtained from each band for information of a frequency region, a time region information generating section B applies inverse quantization to the sampled value after quantization fed from the frequency are information generating section A and encodes the received signal by using a residual signal between the original signal and the signal after band synthesis for re-conversion to the time region signal for the time region information.  In this case, in order to limit the amplitude of the residual signal to be a prescribed amplitude or below, a pulse generated by a pulse generator 12 is added to the input signal by an input signal synthesis section 13 to apply compression- coding to the residual signal. Then reversible compression enable coding is conducted by using a multiplexer section 9 to multiplex the signal from the frequency area information generating section A.

Filed: 1989-02-06
Abstract: PURPOSE:To adjust the focus accurately following up a subject in quick motion by deciding whether a correction is made with a found correction quantity or not by using not only the variation quantity of the moving speed of a subject image, but also its variation rate. CONSTITUTION:The automatic focus adjusting device consists of, for example, an in-camera control circuit PRS, a line sensor device SNS, a motor LMTR, an encoder circuit ENCF, a lens communication buffer circuit LCM, etc. Then the variation rate and variation quantity of the moving speed of the subject image plane position are used by a decision means to decide whether the correction value found by a correcting means is added to the quantity of defocusing detected by a focus detecting means or not. When this decision is made, the variation rate of the moving speed of the subject image plane is used first and when it is judged that the correction value is improper, the variation quantity of the speed of the subject image is used for the decision making. Consequently, the focus can be adjusted accurately following up even the subject in quick motion.

If the raw materials are not in stock at the stockpile place, a failure of the cycle is reported to a control process 8. The control process 8 suspends the child processes 9 to 11 at the end of each cycle of the cycle event process S2 (S7) and decides whether or not a recursive process is needed (S8). When the recursive process is needed, the recursive process is indicated to necessary child processes.  The child processes to which the recursive process is indicated reexecutes the cycle to reallocate raw materials between the factories.
