Title: Phase detecting method and phase tracking loop circuit for digital vestigal sideband modulating communication equipment
Inventor: RI MEIKAN
IPC: H04L27/06
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a phase detection method capable of simplifying a hardware without being sensitive to a Q channel value by obtaining a difference between phase corrected I channel data and an estimated I channel level value, multiplying the code of Q channel data with the difference and turning the operated value to a phase error value. SOLUTION: A digital filter(DF) 310 restores signals Q' by performing Hilbert transformation filtering to the I channel data(chD). In the meantime, a delay device 320 delays the IchD for the filtering time of the DF 310 and obtains the signals I. A complex multiplier 330 phase corrects I and Q' and turns them to the signals I' and Q" and an I channel estimation level is obtained by an estimation device 350. A residual phase detector 360 multiplies the code of Q" to the difference between the signals I" corrected by a cumulative limit value outputted from the estimation device 350 and the I channel estimation level and performs output as a residual phase value. Thus, this phase detection method insensitive to the Q channel for which the DF 310 is not required to be exquisite is obtained.

Title: Power source circuit
Inventor: ISHIGAMI YOSHIHISA
IPC: H02M3/10
Filed: 1983-05-31
Abstract: PURPOSE:To enhance the efficiency of a power source circuit by pulsating an AC power, and applying the pulsating current through a chopping constant-voltage circuit and another constant-voltage circuit to a load, thereby accelerating the responding speed after the power source is energized. CONSTITUTION:An AC power source AC is rectified by diodes D1-D4. The rectified pulsating current is flowed from the collector of a transistor D5 to the emitter, and converted into a DC voltage by a capacitor C1 at a line l2. This DC voltage is applied through a transistor Tr1 of another constant-voltage circuit to a load L as the constant voltage. Since a controller F of the chopping constant-voltage circuit controls the base current of the transistor Tr1 to suppress the variation in the voltage of the load L due to the variation in the load current, it controls the base current of the transistor Tr1. Accordingly, the constant voltage is applied to the load L.

Title: Rotation stop detector
Inventor: WAKIZAKA TAIRIYOU
IPC: G01P13/00
Filed: 1978-08-10
Abstract: PURPOSE: To make it possible to reliably detect the stop of a rotational shaft of low torque with the use of a simple construction in accordance with a fine load torque by using the viscous characteristics of a viscous substance in an effective manner.  
     CONSTITUTION: If a tape recorder is driven, a shaft 25 is turned through a belt 28. By this rotations, a rotating force is applied to a viscous substance in a driven shaft 32 so that this shaft 32 is also turned. By the rotations of this shaft 32, an elastic force is stored in a spring 34, and the rotations of the shaft 32 are stopped at a position where the elastic force is balanced by the rotational viscous force of the substance 33 so that the shaft 25 subsequently rotates by itself. If the shaft 32 is turned a preset angle, a rotor 36 is turned together so that a contact 37 under its connected condition and a brush 38 are rendered inconductive to turn off a switch 40. When the shaft 25 is stopped, the rotating force generated in the substance 33 is eliminated so that the shaft 32 is turned in the opposite direction by the elastic force of the spring 34 thereby to turn on the switch 40.

IPC: H03H9/25
Filed: 1982-06-09
Abstract: PURPOSE:To attenuate spurious surface waves sufficiently, by forming a sound absorbing coating film on a surface acoustic wave filter element with spraying for coating the sound absorbing film on a piezoelectric substrate without unevenness of coating film. CONSTITUTION:A metallic film for electrode is coated on one major plane of wafer 1 made of the piezoelectric substrate with vapor deposition and a resist is coated on the entire surface of the film. A pattern consisting of an input IDT2, an output IDT3 and a shield electrode 4 is exposed on the resist in the lump by using a mask. In melting the exposed section of the resist with development, the pattern comprising the input IDT2, the output IDT3 and the shield electrode 4 to be resisted is formed on the wafer 1. Further, the sound absorbing resin paste having about 500-800CPS of viscosity obtained by solving, e.g., a phenol resin in a solvent having a low melting point, e.g., thinner, is sprayed pressingly on an opening metal mask having a prescribed shape placed closely on a prescribed position on the wafer 1 from a spray gun and coated on the opening metal mask with spraying. After the spray coating, the opening metal mask is exfoliated to form an end surface sound absorbing coating film 5. Since the thinner of a low melting point is used for the paste liquid, the liquid is dried considerably until the particles of the paste liquid is adhered and grown on the wafer 1, and no spread of coating film takes place for the end surface sound absorbing coating film 5 when the opening metal mask is exfoliated.

Title: Acquisition system for priority right of interruption
Inventor: NAGASE HIROSHI
IPC: G06F13/24
Filed: 1980-07-18
Abstract: PURPOSE:To prevent erroneous reception due to a conflict by permitting the processing of one of interruptions requested at the same time on preferential basis and by holding other interruption requests. CONSTITUTION:All circuits are assumed to be cleared. In this case, when an interruption request pulse is generated at the terminal of the (i)-th interruption requesting circuit, a flip-flop (FF) 5 is set via an interruption request line 12. When an interruption priority acquisition bus 4 is not making an interruption request display ''1'', a signal line 11 is at a ''0'' and the output of the FF5 sets a flip-flop 2 via an inhibition gate 1. Further, the output of the FF2 drives a bus driver 3 to make the interruption priority acquisition bus 4 make an interruption display. Once a terminal Si acquires the priority right of interruption, other interruption requesting terminals are inhibited from making interruptions, so a processor processes the interruption of the terminal Si.

Title: Emitter coupling logic circuit
Inventor: TAGO SHIYUUSEI
IPC: H03K19/086
Filed: 1990-04-13
Abstract: PURPOSE:To apply rapid charge/discharge to a load capacitor present on an output terminal with low power consumption and to attain fast switching by increasing a current flowing to an output emitter follower at the fall of an output level and decreasing the current flowing to the output emitter follower at the rise of the output level. CONSTITUTION:Since the current flowing to the collector of a transistor(TR) Q6 is changed quickly with a change in the collector level of a TR Q2 since the wiring capacitance or the like present on the basis of TRs Q5, Q6 is very small, a current IOH1 at the rise of the level at the output terminal and a current IOL1 at the fall of the level at the output terminal flow, respectively to the collector of the TR Q6. Thus, large current flows to the collector of the TR Q6 at the fall of the level of the output terminal to discharge a load capacitor C1, thereby falling the level rapidly, and the current flowing to the collector of the TR Q6 at the rise of the level of the output terminal is decreased to charge the load capacitor C1 according to the driving capability of the TR Q5, thereby raising the level rapidly.

Title: Thermal printing system

Filed: 1978-08-15
Abstract: PURPOSE:To provide a thermal printing system which can type in desired density by controlling the heat generating amounts of respective heat generating elements provided correspondingly to the respective picture elements using high speed trigger control elements. CONSTITUTION:To a terminal 2 is applied a voltage capable of sufficiently supplying energy necessary for a generating element P1 as required to flow a current sufficient to hold the conductive state of a high speed trigger control element 3 such as a thyristor for time required to type. Then, a heat generating element selection signal is applied to one input terminal C1 of two-input AND gate 4, and synchronous signal is applied as a trigger pulse to the other input terminal T1 to allow the AND gate 4 to produce a logic product output, which is applied to the control terminal of the thyristor 3 to thereby conduct the thyristor 3. As a result, a current I1 will flow through the element P1. After predetermined current is thus flown through the element P1, the voltage applied to the terminal 2 is decreased to zero to thereby again shut off the thyristor 3. Thus, predetermined picture element can be typed.
