IPC: H02J9/06
Filed: 1985-08-30
Abstract: PURPOSE:To adjust the test of the titled control of parallel operation by connecting a predetermined impedance element between an output terminal for an inverter pole having phase representing the internally generated voltage of an inverter and a commercial power supply. CONSTITUTION:When the corresponding current value of a reactor 121 is 1A to the rated current of an inverter 1, the impedance 2 of the reactor 121 is set so that the current of the reactor 121 reaches 1A when the inverter 1 is brought to the state of the operation of a rated output. The impedance of the synthetic impedance of a transformer 120 and the reactor 121 is approximated to the synthetic impedance of an output transformer 101 and a reactor 102 for a filter. A capacitor 126, an impedance ratio thereof is reduced in response to a capacitor 103 for a filter, is mounted. A signal imitating output currents from the inverter 1 is obtained by closing a switch 122 under the state in which an output switch 104 is opened.

Title: Pilot signal automatic monitoring/control system
Inventor: SHIGETA KOJI
IPC: H04B7/15
Filed: 1988-07-29
Abstract: PURPOSE:To reduce the number of the stations necessary for the network of a pilot signal automatic monitoring/control system by sending a reference pilot signal alternately with the same frequency with two stations. CONSTITUTION:A reference station intermittently sends a reference pilot signal 6 with a timing of the self-station to a free-run. Next, a back-up station receives the pilot signal 6 from the reference station, sets a self-station pilot sending timing from the timing and sends intermittently a pilot signal 7 to the middle of the pilot signal 6 from a reference station. At the monitoring station, the time when the pilot signal of two stations is intermittently inputted to a receiver at the level in the standard always is normal and it is judged that when only one wave out of two stations is inputted, an abnormality occurs at the pilot transmitting station not inputted and the transmitting system to the satellite.

Filed: 1988-07-29
Abstract: PURPOSE:To improve the speed control characteristics for a head by providing a filter for smoothing an output of a target speed generator between the target speed generator and a subtractor. CONSTITUTION:The filter 13 for smoothing the output of the target speed generator 9 is additionally provided between the target speed generator 9 and the subtractor 10.

Then, an actuator 11 is driven by a drive current outputted from this drive circuit 12, and this drive current is suppressed enough in its ripple part. By this method, the speed suppression characteristics and accuracy of the magnetic head are improved.

Filed: 1991-07-31
Abstract: PURPOSE:To record a visible image newly on a recorded visible image by imparting recording energy or erasing energy selectively on an energy imparting means at every recording dot or erasing dot. CONSTITUTION:The recording layer 28 of a card 10 looks cloudy and opaque under the room temperature, and it is changed to a transparent one when temperature rises to prescribed temperature, and it keeps transparency even when the temperature returns to the room temperature. Also, it is a recording material provided with a feature capable of keeping the state opposite to the above state. The erasure of the visible image on the recording layer 28 of the card 10 by a heating resistor string 31 is performed by increasing the temperature of the heating resistor in accordance with a space dot 35 to be erased to a temperature area to make the recording layer 28 into transparency irrespective of the recorded image. Therefore, the heating resistor is heated as carrying the card 10 underneath the fixed heating resistor string 31 in the arrow head direction. As a result, it is possible to easily and stably perform, for example, overwrite recording to write an image L newly on an old image I.

Title: Frequency division circuit
Inventor: SUZUKI MITSUO
IPC: H03K23/00
Filed: 1987-07-31
Abstract: PURPOSE:To make the duty nearly 50% by providing an n-stage of D type FF, a logic circuit, and a D type FF circuit using an output of the logic circuit as the clock input, using the inverted output as the data input and using the output signal for plural D type FF input data. CONSTITUTION:The output signal S10 of the D type FF5 goes to H at time t1 when the clock signal S2 rises at first from a time t0 when a reset signal S1 goes to H. Since the D type FF3 uses the clock signal inverted by the inverter 7 to latch the signal S10 at a time t2, the signal S6 goes to H. The said D type FF5 inverts the output synchronously with the time t3 when the clock signal S2 descends next and the output signal S10 goes to L. Since the D type FF3 latches the signal S10 at a time t4, the signal S6 goes to L. In checking the output signal S10 of the D type FF5, the duty is brought into 50%.

Title: Check method for data transmission
Inventor: AIZAWA HIROSHI
IPC: H04L1/00
Filed: 1987-07-31
Abstract: PURPOSE:To improve the reliability of data transmission by adding a parity bit formed by exclusive OR of adjacent data among data of plural bits being source data and coding the result so as to apply error detection based on the value obtained through the combination of different parity bits and data at the reception side. CONSTITUTION:Data D1-D3 are source data and each consists of 8-bit. The parity bits P1-P3 in 8-bit formed by the exclusive OR of adjacent data are added among the data D1-D3. They are arranged as P1, D1, P2, D2, P3, D3 as shown in figure and they are coded and sent to the reception side. The reception side applies the decoding to them and checks the parity bit to discriminate the presence of an error. That is, when only one parity bit is correct and others are not correct, and when the value obtained from the different combination of the data and parity bit is equal, it is regarded as a correct data, which is used for the correction. Thus, after code correction is applied by BCH or Hargelburger, the code correction is applied newly among the parities and data.

Title: Damping device for parallel suspension strip body
Inventor: KAGAMI MASAAKI
IPC: F16F15/02
Filed: 1988-08-02
Abstract: PURPOSE:To make improvements in the effect of a vibration absorbing means by installing a deflection arresting string in and around the vibration absorbing means of a suspension strip body so as to form it into a radial form on a projected surface orthogonal with the strip body between the strip body and the end's relative static member, and preventing any vibration at the same phase of plural pieces of the suspension strip body by a dragging effect. CONSTITUTION:When a building with an elevator is shaked by an earthquake or the like, plural pieces of main ropes 3 and weight compensating ropes 8 rock as elastically engaging sponge mats 10, 12 individually at each rope. Therefore rocking energy of these ropes 3 and 8 is absorbed by these mats 10, 12. Here ropes 3-1 - 3-5 receive such a restraint that tries to elongage each arresting string as long as more than the specified length in the horizontal projected direction of the arresting string by arresting strings 11-a - 11-d and ropes 8-1 - 8-5 in the rope 8 by arresting strings 13-a - 13-d, respectively. Consequently, the rope under restraint by the arresting string performs such a rocking motion as different from the rope that is unrestrained or restrained by an arresting string of another radial angle at the engagement position between both these mats 10 and 12, so that a damping effect is improved.

Filed: 1990-07-19
Abstract: PURPOSE:To reduce variation of tension without receiving the mechanical effect of a looper by controlling the speed of a motor for a looper by using the speed corrected with the signal for the difference between a reference value of speed and a measured value of speed and the deviation between a reference value of tension and a measured value of tension. CONSTITUTION:In a looper central device which is provided for absorbing a difference of the passing which tension is beld in constant when the passing speeds are different between two sections, sped detectors 10, 11 detect the passing speed. The speld reference signal is corrected by speed correction devices 14,15 through a signal for the difference between the detected value and the speed reference value preset in each section. The speed reference for the looper is made by using the corrected speed value and the deviation between the tension value detected by a tension detector 12 provided in the looper and the tension reference value to control the speed of a looper motor 5. Consequently, the variation of tension can be reduced without receiving the effect of the mechanical friction of the looper.
