Title: Deflection scanner
IPC: G02B26/10
Filed: 1992-03-18
Abstract: PURPOSE:To realize the deflection scanner provided with a rotary polygon mirror which can be rotated at a high speed by a small motor driving current, and also, whose rise time is short. CONSTITUTION:The deflection scanner A1 consists of a shaft 3 supported so as to be freely rotatable by a ball bearing 2 fixed to a housing 1, a flange 4 fixed to the shaft 3, a rotary polygon mirror 6 pressed against the flange 4 by holding spring 5, a rotor magnet 7 stuck to the lower face of the rotary polygon mirror 6, and a field coil 10 mounted on a motor substrate 9 fixed to the housing 1. Since the rotor magnet 7 is coupled directly to the rotary polygon mirror 6, a rotating body containing both of them is small in size and light in weight. Accordingly, it will surface that a motor driving current for driving a motor M1 consisting of the rotor magnet 7 and the field coil 10 is small. Also, since inertial force of the rotating body is small, a rise time is also short.

Title: D/a converter
Inventor: SHIMOBAYASHI MASARU
IPC: H02M7/25
Filed: 1987-04-14
Abstract: PURPOSE:To easily secure noise margin with respect to a power voltage by combining a D/A converter and a transformer so as to obtain a high voltage D/A circuit with high digital resolution. CONSTITUTION:The titled circuit consists of an AC power supply 11, (l)-set of transformers 121-123 whose winding ratio is respectively n1, n2,...n1, a rectifier/smoothing circuit 13, a D/A converter (l)14, a D/A converter (2)15 and a D/A converter (l)16. Since outputs of the D/A converters with a digital data set thereto are processed as AC by an AC power supply 11, the signal is transformed in response to the transformer winding ratio n1, n2,...nl at the transformers 121-123 and outputted as the summed AC power at the secondary winding of the transformers 121-123. The AC power outputted from the secondary winding of the transformers 121-123 is inputted to the rectifier/smoothing circuit 13, where the power is transformed into a DC power corresponding to the set digital data. Thus, noise margin with respect to the DC power voltage is ensured.

Title: Signaling detection circuit
Inventor: NOMACHI YOSHIO
IPC: H04W84/02
Filed: 1987-04-15
Abstract: PURPOSE:To prevent an exchange from terminating its call due to mis-information during communication by outputting an output signal of a detector or a waveform shaping circuit as a signaling signal only when the output signal is a signal allowed as the signaling signal. CONSTITUTION:When the signaling signal by the interruption of a prescribed frequency is inputted to a BPF 2 from an input terminal 1, the signal is converted into a DC pulse and inputted to a waveform shaping circuit 4, where the signal is waveform-shaped and inputted to a comparator 6. The comparator 6 compares the signal with a preset reference level and only when the level is larger than the reference level, the control signal being at a prescribed level is outputted. When the level is larger than the reference level, the gate circuit 7 sends the output signal of the waveform shaping circuit 4 to an output terminal 5 and when the level is smaller, the transmission to the output terminal 5 is blocked. Thus, the output signal of the waveform shaping circuit 4 becomes the signaling signal equal to the initial signaling signal and the result is outputted from the output terminal 5.

Title: Power supply circuit
Inventor: YAGI SOUICHI
IPC: G05F1/56
Filed: 1983-05-27
Abstract: PURPOSE:To reduce the mean value of an overcurrent and to reduce the heating value of a parts by switching the charge/discharge of a capacitor in response to the presence or absence of the output of an overcurrent detecting circuit, and turning on and off a switching circuit in accordance with the charge/discharge state. CONSTITUTION:An output 8a is given to a load which always needs electric power from an accumulator 4 via an overcurrent detecting circuit 1, stabilizing circuit 6 and a switching circuit 3. While an output 8b is fed to an intermittent load via a switching circuit 7 by turning on and off a switch SW5. When the overcurrent flows, a transistor TR12 is turned on to start charging a capacitor 21a. Then a TR23 is turned on when the capacitor 21a reaches a fixed level of voltage Vc, and therefore TR32a and TR32b are turned off. Thus an overcurrent state is released. The capacitor 21a discharges through the resistances 22a and 22b. Then the TR23 is turned off with the TR32a and TR32b turned on, respectively when the level of the Vc is lowered. However said break and restoration are repeated again in case the factor of the overcurrent is not eliminated. Therefore, the mean value of the overcurrent is lowered and the heating value of each part is reduced. Thus a power supply circuit can be protected.

CONSTITUTION:In order to prevent an ultrasonic wave from being diffused, a curved surface vibrator 1 provided with a curvature is fixed, and a wedge 8 made of plastic, for propagating a converging ultrasonic wave is attached to a columnar fixed member 3. A ring 9 made of plastic rotates round the outside periphery of the wedge 8, and also, attached to a rotating body 4 for rotating round the periphery of the fixed member 3.

Moreover, a rotary mechanism between the fixed member 3 and the rotating body 4, and a seal member 11 of a bearing type which serves as a seal of an ultrasonic propagation medium 2, as well are provided. Since the wedge 8 is made of plastic, the acoustic impedance is close to that of the soft rubber tire 10, and that of a degree of the same material as the wedge is used for the ring 9, by which the propagation efficiency of an ultrasonic wave becomes higher.

Abstract: PURPOSE:To perform information gathering of high precision and efficient operation by forcibly inhibiting the bus access from an input/output device simultaneously with the stop of the operation of a central processing unit and releasing inhibition of this bus access simultaneously with the restart of the operation. CONSTITUTION:When a central processing unit CC 10 is stopped to inhibit the change of the system state due to the bus access from an input/output device IO for the purpose of performing soft debugging or trouble searching, an operation stop signal 200 of an IO 50 is set to '1'.

Abstract: PURPOSE: To obtain high frequency oscillation having good response and high output by fitting a piston in the cylinder body provided with a supply port and an exhaust port for pressure fluid and applying the supply and exhaust of the pressure oil to two fluid chamber with different pressure-receiving areas using a rotary valve.  
     CONSTITUTION: The rotor's ports 55, 54 get pressure corresponding to the supply and return sides, respectively, when supply pressure oil is applied to No.2 fluid chamber 13 at the upper left of the piston 2, i.g. the smaller pressure-receiving area 23. When a valve rotor is turned, the open port 45 comes into communication with the rotor ports 54, 55 alternately and the supply fluid stops at the rotor port 55 while it is in communication with the rotor port 54. The exhaust port 32 is, on the contrary, put into communication with No.1 fluid chamber 12, when the piston 2 shifts to the right as the fluid pressure in No.2 fluid chamber is higher. When the open port 45 is in communication with the rotor port 55, pressure is applied to both No.1 and No.2 fluid chambers 12, 13 alike as the abovementioned state, and because the pressure receiving areas 22 is larger than the pressure receiving area 23, the piston 2 shifts to the left and the supply port 31 is put into communication with the exhaust port 32, actuating the piston 2 into vibratory operation.
