Inventor: SEO NOBUHIDE
IPC: F02D41/04
Filed: 1991-01-14
Abstract: PURPOSE:To always properly control the actual air-fuel ratio regardless of fluctuation of fuel supply characteristic by setting a correction fuel supply amount in accordance with a difference between time for detected air-fuel ratio to reach the target air-fuel ratio and the reference time, when air-fuel ratio of a mixture is open loop-controlled. CONSTITUTION:Air-fuel ratio of a mixture in an engine is detected by a means A. An operative condition of the engine is detected by a means B. Further, a fuel supply amount to the engine is respectively feedback-controlled or open loop-controlled by a means C so that the detected air-fuel ratio of the mixture respectively agrees with the first or second target value in accordance with the detected operative condition of the engine. Here at the time of transfer from feedback control to open loop control, time for the air-fuel ratio of the mixture to reach the vicinity of a change limit level is measured by a means D. A correction fuel injection amount in accordance with a difference between the measured time and the reference time by a difference between the first and second target air-fuel ratios is set by a means E to correct the amount based on the open loop control.

Title: Holding method for expansion and contraction of hydraulic cylinder and its hydraulic circuit
Inventor: WADA SUSUMU
IPC: F15B11/08
Filed: 1982-01-11
Abstract: PURPOSE:To maintain the state of stoppage of the hydraulic cylinder positively by a method wherein the operation of expansion and contraction of the hydraulic cylinder is stopped, an oil chamber at the load holding side (the push side or the pull side) of the hydraulic cylinder is supplied with pressure oil from a pressure oil supply source different from a main pump, oil pressure in the oil chamber is maintained at predetermined pressure and oil pressure is maintained  at prescribed pressure. CONSTITUTION:When the temperature of pressure oil flowing into the oil chamber 43 at the push side drops, pressure oil in the oil chamber 43 at the push side is shrunk gradually with the temperature drop. In this case, pressure in the oil chamber 43 drops gradually because inner volume in the oil chamber 43 at the push side is determined. When a direction control valve 2 is returned to a neutral position, oil discharged from an auxiliary pump 6 is introduced in the direction of the arrow (e) when a changeover valve 7 is changed over previously just before a boom 5 drops at that time, and flows into the oil chamber 43 at the push side, thus preventing the shrinkage of an expansion cylinder 4 and the boom 5.

Abstract: PURPOSE:To contrive the decrease of a circuit scale by applying voice detection while using it as an ADPCM code without PCM-decoding an Adaptive Differential Pulse Code Modulation (ADPCM) voice signal and sharing a part of the ADPCM coder. CONSTITUTION:The output of a 1st integration circuit 3 and the output of a 2nd integration circuit 4 are given to a deciding circuit 5, where the difference of both is obtained, the difference and a threshold level given separately from a threshold input terminal 6 are compared, and when the former is larger than the latter, a signal indicating 'presence of voice signal' is outputted while indicating the variance of the input signal is large, and when the former is smaller than the latter, a signal indicating ' absence of voice signal' is outputted to the next stage of output holding circuit 7 respectively. In the output holding circuit 7, when the output of the deciding circuit 5 changes from the state of 'prsence of voice signal presence' into 'absence of voice signal', a predetermined time is added to the output of the deciding circuit 5 as the voice presence period and the result is outputted from an output terminal 8. Thus, the voice detection is applied with the ADPCM signal as it is without PCM- decoding.

Title: Sample and hold circuit
Inventor: FUEKI SHUNSUKE
IPC: G11C27/00
Filed: 1989-01-10
Abstract: PURPOSE:To reduce the cost and to make the circuit small in size by using one A/D converter so as to allow the circuit to cope with plural analog signals. CONSTITUTION:When analog switches S11, S12 are switched sequentially while being synchronously with each other, corresponding analog signals A11-A1n are sampled and held in plural sampling circuits B11-B1n. Then when the analog switch S13 is switched to connect the circuit B11 and a storage means 13, for example, then a sampling charge stored in the circuit B11 is stored in the storage means 13, the stored charge is converted into a digital value by the A/D converter 14 and outputted. That is, in the case of converting digitally plural charges stored in the sampling circuits B11-B1n, one A/D converter 14 is enough for the purpose. Thus, the cost is reduced and the circuit is made small in size.

Title: Communication state discriminating method for optical fiber communication line.
Inventor: WATANABE ICHIRO
IPC: H04B10/079
Filed: 1987-01-12
Abstract: PURPOSE:To discriminate a communication state at an optional part of an optical fiber communication line by extracting a part of an optical signal from an optical fiber cable and converting it into an electric signal and comparing the electric signal filtered by a band pass filter with a reference level. CONSTITUTION:A part of the optical signal propagated in the optical fiber 11 is led to a photodetector 12, converted into an electric signal and amplifier and filtered by band pass filters 14a, 14b having a different band pass characteristic. Then the result is averaged timewise by averaging device 15a, 15b and the level difference is detected by a comparator 16. Whether or not the output of the comparator is in the communication state or the non communication state is identified by comparing the output of the comparator with a reference level set to the intermediate level between the output of the averaging devices 51a, 51b at non communication and the output of the averaging devices 15a, 15b at communication by means of a threshold level discriminator 17. Thus, the information relating to the communication state is acquired at the optional position of the optical fiber line.

Abstract: PURPOSE:To optimize the increasing factor of fuel injection quantity in warming up an engine by defining the factor by use of a specified equation based on the increasing factor and correction factor according to water temperature and continuous time respectively and reducing the correction factor according to the continuous time corresponding to the continuous time required for a fixed number of engine revolution or more. CONSTITUTION:When in operating an engine, an increasing factor TLFWL based on the value of water temperature THW at that time is read out referring the specified map and memorized. In the next step, whether engine speed is in a predetermined level (2,000rpm) or more or not is judged, and if it is NOT, a correction factor TKWL determined according to continuous time is set to (1.0) on as initial value. Then, a continuous time counter is cleared. On the other hand, when it is YES, the continuous time after that is calculated to obtain the correction factor TKWL corresponding to the continuous time. In the next step, the increasing factor FWL of fuel injection quantity in warming up the engine is operated from the equation FWL=TLFWL*TKWL+1.
