IPC: G06F3/06
Filed: 1980-08-28
Abstract: PURPOSE:To ensure the accurate decision for the presence or absence of a record even when plural types of control are switched irregularly, by performing the couting based on the storage value stored in a head code position register and presuming the retrieving position of the next head code. CONSTITUTION:A head code is stored in a head code position register 209 via a head code retrieving circuit 206 and a head position counter 203.

Filed: 1988-05-16
Abstract: PURPOSE:To eliminate a mechanical switch, to make inexpensive a device and to enhance operability by writing a key word for a control data area, and using a RAM area where the control data area exists as a ROM. CONSTITUTION:When a key word is set for the control data area of a RAM 104, said area is prohibited to be written by a control circuit 102. When a malfunction is generated, a pulse to be periodically outputted to a signal line 121 is eliminated, a CPU 101 is reset by a runaway detecting circuit 107, and control equipment is initialized. When the periodical pulse is not outputted to a line 121, the circuit 107 generates a reset signal 122 to the CPU 101. A control signal 123 controls the bus buffer 106. A signal 125 is an ERR signal, which detects that a write action is erroneously executed in a soft volume area when the soft volume area has been set at the ROM, and it is connected to the interrupting terminal of a CPU 104.

Abstract: PURPOSE:To reduce the number of information lines, by transmitting column information and row information of a key matrix from an attendant switchboard to a switch board in a time-division mode. CONSTITUTION:Scanning pulses of key matrix 1 are being sent out from scanning control circuit 6 via column counter 4 and row counter 5. An operator turning ON any key, the output signal of counter 4 is decoded 2, applied as a column selective pulse to multiplexer 3 via the cross point, and returned to circuit 6 as row information. When the row information pulse is received, circuit 6 actuates transmission control circuit 9 at the same time when setting the value of counter 5 to units-digit transmission circuit 7 and the value of counter 4 to tens- digit transmission circuit 8. Consequently, the key information of matrix 1 is transmitted to the switchboard as a two-digit dial number.

Abstract: PURPOSE:To improve the accuracy of a rotation synchronizing signal by providing a magnetic recording layer formed with magnetic recorders having different magnetizing directions in the concentrically annular regions of a rotor at a predetermined pitch and emitting a laser light to the layer to obtain the rotation synchronizing signal. CONSTITUTION:A laser light emitted from a semiconductor laser 18, i.e., an emitted light 34 has a polarizing surface 34a. The emitted light 34 is reflected on a magnetic recording layer to become a reflected light 35, and the polarizing surface 35a of the light 35 is rotated at a certain angle with respect to the polarizing surface 34a of the light 34 by means of magneto-optical effect. Thus, the light 35 varies at the angle of the polarizing surface 35a at the period of the frequency responsive to the rotating speed of a rotor yoke. When the light 35 passes a photodetector 22 by a beam splitter 20, the difference of the rotary angle of the polarizing surface 35a is converted to the intensity of the light. The intensity of the light is converted by a photodetector into an electric signal to obtain a frequency signal by a voltage output.

Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To automatically suppress vibration caused by an excavating part by providing a damping device, put in damping action by an antiphase signal, at an excavating part or a lower part of a bucket elevator. SOLUTION: During operation, vibration is detected by a vibration detecting device 1, and vibration waveform is passed through a filter 2 to take out vibration waveform of object frequency. The filter 2 can be so formed as to have several kinds of frequency pass bands, and the vibration waveform of its maximum level can be used. An antiphase signal generating part 3-1 has a predetermined reference level, starts action when the level of the vibration waveform from the filter 2 exceeds this reference level and outputs an antiphase signal with an antiphase to the vibration waveform. A phase fine adjustment part 3-3 monitors the vibration value from a vibration value detecting part 3-2 and outputs the antiphase signal. A damping device 4 is vibrated by this antiphase signal and acts in such a way as to nullify vibration caused by an excavating part.
