Title: Signal processing circuit
Inventor: TAKAZAWA ATSUYUKI
IPC: H03M1/18
Filed: 1994-06-02
Abstract: PURPOSE:To easily process an analog signal over widespread amplitude without switching an attenuater by respectively amplifying and attenuating the inputted analog signal and synthesizing the signals, which are respectively A/D converted, with each other. CONSTITUTION:One side of the input analog signal is amplified 12 and its amplitude is clipped 14. On the other hand, the other side is attenuated 13 and its phase is adjusted 15. Then both sides are simultaneously A/D converted by an A/D converter 16 and inputted to a digital arithmetic circuit 17. A circuit 17 is composed of an output synthesizing circuit and an effective value arithmetic circuit so that a digital value from the first converting circuit of the converter 16 is inputted to the output synthesizing circuit first to be converted by a rate corresponding to the amplifying rate amplified before. On the other hand, a digital value from the second converting circuit of the converter 16 is converted by a rate corresponding to the attenuating rate attenuated before. A value obtained by synthesizing these converted value is inputted to the effective value arithmetic circuit so as to calculate an effective value to be outputted as a digital signal. Thus, without switching the attenuater, the analog signal can be processed over widespread amplitude.

Title: Shovel system construction machine
Inventor: NAKAJIMA MASATO
IPC: B60K28/14
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To decrease the possibility of turning-over and lying on its side, by providing an automatically slewing control means stewing the working part to the opposite direction against the turning-over direction expected by a turning-over estimate means. SOLUTION: An inclination sensor 12 detecting the lateral inclination of the upper slewing body of a construction machine is arranged at the nearly central part of the right and left sides of the upper slewing body to lessen the detection error as much as possible. The control part 13 is provided with a control program of the slewing control of the boom or the like by which an electromagnetic changeover valve 16 or the like for a slewing cylinder is controlled on the basis of the detected signals of the sensor 12. When an inclined angle of the upper slewing body is larger than an estimation base value of turning-over, the inclination direction of the body is judged in the slewing control part of the boom. And when the judged inclination direction is the right side, the valve 16 is changed over to the left slewing side.  And the gravitational position of the machine body deviated to the inclined side is displaced to the reverse side to automatically slue the boom to the reverse direction against the inclination direction. And as a result, the possibility of laterally turning-over and lying on its side is lessened.

IPC: G11B11/10
Filed: 1984-06-15
Abstract: PURPOSE:To separate completely an optical head from a recording area where prescribed information is recorded, by continuing driving the optical head for a certain period after a prescribed volume of information is reproduced from a recording medium having no tracking tracks. CONSTITUTION:When an instruction signal of reproducing of information recorded on a photomagnetic disc 2 is sent, a sequence control circuit 17 moves an optical head 3 to the start of an area A, where desired information is recorded, through a head driving circuit 19. When terminating the head access processing, the circuit 17 presets the number of horizontal synchronizing signals HS, which corresponds to one page, to a page end counter 16. The head 3 is driven in a certain speed thereafter, and counting of the signal HS obtained from the reproduced signal is started in the counter 16, and a reproducing end signal is outputted when the counter value reaches the preset value. The circuit 17 sets a timer circuit 20 and stops the head 3 after counting a certain period. Thus, the head 3 is separated from the area A to reproduce always stably information.

Abstract: PURPOSE:To erase the drifting voltage of a photodetecting circuit without deteriorating the noise and band characteristics of the photodetecting circuit, by constituting the titled circuit by the photodetecting circuit in which a photodetector and a preamplifier is directly coupled, an LPF to input the output voltage of the photodetecting circuit and differential amplifier circuit to input both the outputs of the photodetecting circuit and the LPF. CONSTITUTION:Drifting voltage generated by the photodetector 1 or the preamplifier 2 due to the temperature change of the photodetecting circuit 9 is applied both the input terminals 13, 14 of the differential amplifier 12 as it is. Although a high-frequency signal component is inputted to the input terminal 13 of the differential amplifier 12, the component is not inputted to the input terminal 14 because the component is removed by the LPF 11. In the differential amplifier 12, the high-frequency signal component is amplified and outputted from an output terminal 15, but a low-frequency component, i.e. a drifting voltage component generated in the photodetecting circuit 9 is offset and is not outputted from the output terminal 15. The LPF 11 is formed by a capacitor 21 with large capacity and the input impedance of the input terminal 14 of the differential amplifier 12.

Filed: 1988-05-20
Abstract: PURPOSE:To automatically supervise the abnormality of an input speed for a low order group signal at a low cost by providing a speed deviation detecting circuit to detect the input speed deviation of the low order group signal. CONSTITUTION:A stuff multiple converting device is composed of a bipolar  unipolar converting circuit 1, a transmitting memory 2, a monitor terminal 7-1 and a speed deviation detecting circuit 21. The speed deviation detecting circuit 21 for the input speed of a low order group signal S1 decides the presence and absence of abnormality generation in the input speed deviation of the low order group signal S1 by deciding whether the generating period of a stuff control signal S7, which is generated by a stuff control circuit, is in a period range to correspond to the allowed speed deviation or not, for example. Then, when the abnormality is generated, a warning signal is generated. Thus, the abnormality of the input speed for the low order group signal can be automatically supervised at a low cost by the addition of the simple circuit.

Filed: 1998-05-01
Abstract: PROBLEM TO BE SOLVED: To provide a ceiling wall forming method using a membrane body allowing a ceiling wall to be formed in desired shape even in the case of a huge ceiling wall. SOLUTION: An outer peripheral edge of a membrane body 20 is airtightly fitted to a concrete bottom plate 1. Compressed air is supplied into airtight space inside the membrane body 20 to expand the membrane body 20, and the pressure of the airtight space is kept to the first value. Concrete is sprayed onto the membrane body 20 up to the height of about 4/10 of the height of the membrane body 20 to form a first layer of a first concrete wall 1402. While the concrete forming the first concrete wall 1402 has fluidity, the pressure of the airtight space is raised to the second value higher than the first value to lift the first layer of the sunk first concrete wall 1402 up to the initial position to adjust the shape of the first concrete wall 1402. The first layer concrete wall is thus formed upward every area while heightening the pressure of the airtight space.

Filed: 1983-07-06
Abstract: PURPOSE:To more exhibit the cancelling effect even in case of a stereo signal by constituting a cancelling system divisionally with a system for main signal and a system for subsignal. CONSTITUTION:The cancelling system for main signal consists of a differentiator 10, a multiplier 11, and an adder 12 to perform multipath cancel. The cancelling system for subsignal consists of a differentiator 13, a multiplier 15, and a subdetector 16, and cancel in the subsignal region is possible if the phase, the gain, and the characteristic of the differentiator 13 are matched to a subsignal.
