Title: Orthogonal frequency division multiplex modulator-demodulator
Inventor: YAMADA SHINJI
IPC: H04J11/00
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To allow transmission and reception of an orthogonal frequency division multiplex(OFDM) modulation wave without provision of a special radio equipment by generating an OFDM modulation signal for a base band. SOLUTION: Transmission data fed to an input terminal 1 at a transmitter side are given to an S/P conversion circuit 26, where the data are S/P-converted and a conjugate complex data supply circuit 27 generates data of k=N/2, (N/2)+1,..., N-1. The data are fed to an IFFT(inverse fast Fourier transform) circuit 28, in which fast discrete Fourier inverse transform is conducted. As a result, since digital data of the orthogonal frequency division multiplex(OFDM) modulation wave are outputted to a real component modulation output of the IFFT circuit 28, the data are D/A-converted by a D/A converter circuit 29, after a harmonic component is eliminated by an LPF 30, an OFDM modulation wave for a base band is outputted from an output terminal 31.

Title: Open bus detection method for transmission system
Inventor: SUZUKI ATSUHIKO
IPC: H04B3/46
Filed: 1989-10-30
Abstract: PURPOSE:To detect a fault quickly and to attain proper countermeasure by supplying a same current to two transmission lines so as to be finally supplied to a secondary winding of each pulse transformer of each node and discriminating it in the event of disabled communication that either of the two transmission lines is broken. CONSTITUTION:A control circuit 33 of a fault diagnostic device 9 outputs a signal at the detection of a broken line to close switching circuits 30-32 to connect transmission lines 2, 3 to a power supply +Vcc and to connect a transmission line 4 to ground GND. Suppose that the transmission line 3 is broken at a point P, then a current 1 flows from the power supply +Vcc to the transmission line 2 but does not flow to the transmission line 3. Thus, the current I flows from one direction of terminal 12a to 12c to a secondary winding 12 of a pulse transformer 10 connecting to the transmission lines 2, 4 of a node 5 to unbalance the current in the secondary winding 12, resulting that the core of the pulse transformer 10 is saturated. As a result, no communication is enabled for the node 5.

CONSTITUTION:The conditions are set as follows: the depth of water is 10m, and W, F, P are the weight of a weight, a floating body, and a piston, respectively. In order that the weight and the floating body, and the internal piston are engaged with each other to lift the weight and lower the floating body and the internal piston, W must be smaller than the sum of P and F. In order to lift the floating body and the internal piston, and to lower the weight, the sum of P and F must be smaller than W. Under the condition where the floating body is lowered and water pressure is applied to its upper face, and the air F1 is not sucked into the inside, the sum of sh1 + sh2 is equal to sh3, if sh1, sh2, sh3 are the water pressure in a recessed part, the water pressure applied to the lower end of a diaphragm F11, respectively. Accordingly, the work required to lower the piston inside the floating body and to obtain the air sh will be : Wh + Q = sh. When P + F is lowered by reducing P + F below W, energy is given to W.

Title: Finned heat exchanger
Inventor: OBATA MAKOTO
IPC: F25B39/02
Filed: 1984-12-27
Abstract: PURPOSE:To uniform the layer of frost between fins by a method wherein the surface of respective fins is formed into the shape of waveform and the width of waveform is constituted so as to be increased stepwisely as the fin approaches the outflow direction of airflow. CONSTITUTION:In the inflow part of airflow of the corrugated fin 4, the height H of the waveform of the corrugated fin 4 is low and the air stream is not disturbed so easily, therefore, an absolute humidity difference between ambient air and saturated humid air becomes small. As a result, the thickness of the layer 3 of frost at the inflow part of air of the corrugated fin 4 becomes thin. Since the height H between the crest and trough of the corrugated fin 4 is increased as the position of the fin approaches to the outflow direction of air, the disturbance of air is generated gradually and heat exchange is effected between cooled and dehumidified air whereby the layer 3 of frost is formed. Accordingly, the frost 3 on the surface of the corrugated fin 4 becomes the layer of frost having an uniform thickness and air ventilating path may be secured widely, therefore, the deterioration of heat exchanging amount may be reduced.

Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To immediately stop the opening and closing operation even if a person is caught in the opening and closing door by causing the opening and closing door to discharge when a peson touches the opening and closing door, and stopping the operation of the opening and closing door by the discharge. SOLUTION: According to a command of a controller 6, a charging part 4 applies an electric charge to an opening and closing door 1, and when the charges of the opening and closing door 1 amount to a designated value, the supply of voltage to the opening and closing door 1 is stopped. In such a charging condition, normally, when an opening and closing sensor 2 functions every time a person goes in and out, the opening and closing door 1 is automatically opened and closed by a driving source 3. The moment a person touches an arbitrary place of the opening and closing door 1, a grounding circuit is formed among the opening and closing door 1, the person and the ground, whereby the opening and closing door 1 is discharged by the person's touch. When the discharge is detected through a discharge detecting part 5 by the controller 6, a signal for the stop control is sent to the driving source 3 of the opening and closing door 1 to immediately stop the driving source 3. Thus, the opening and closing door 1 stops its operation at that position.

IPC: H02N1/00
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic wobble motor having large rotational torque and holding torque by improving electrostatic attracting forces by increasing the effective areas of electrostatic coupling, by constituting a rotor electrode in such a way that the electrode can simultaneously come into contact with upper and lower stator electrodes. SOLUTION: Stator electrodes 15a and 15b are disposed to face oppositely each other on both sides of a rotor 23a. When the same potential as the ground potential is applied upon the upper and lower stator electrodes 15a and 15b which are positionally shifted from each other by 180 deg. under the condition, a rotor electrode 17 comes into contact with insulating layers 21a and 21b and electrostatic attracting forces are generated. Consequently, the rotor 23a makes precession synchronously to the drive of the electrodes 15a and 15b, because the rotor electrode 17 is sequentially attracted to the electrodes 15a and 15b.  Therefore, an electrostatic wobble motor having high durability and driving reliability can be obtained, because the effective areas of the electrostatic coupling between the rotor electrode 17 and stator electrodes 15a and 15b become larger and the generated electrostatic power is increased.
