Title: Fault detection circuit for receiver
Inventor: YONEYAMA YUZO
IPC: H04B17/29
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To detect with a simple configuration faults, including deterioration in a noise figure of a receiver. SOLUTION: A fault detection section 4 controls a changeover circuit 5 to select a noise generator 6, and the noise signal is outputted to a reception electric field detection section 3 via a reception section 2, resulting in that a level given to the reception electric field detection section 3 is obtained from an electric field information voltage (b) outputted from the reception electric field detection section 3, to obtain a gain G of the reception section based on the level. The gain is compared with a gain in a normal state to detect a fault of a receiver. Then the fault detection section controls the changeover circuit to select a termination resistor 7 for allowing the resistor to receive only thermal noise. Simlarly, a level received by the reception electric field detection section 3 is obtained.  Since the gain G of the reception section is already known, it is possible to obtain a noise figure NF of the reception section from the gain G.

Title: Stereoscopic picture display system
Inventor: TANIGUCHI YUKIO
IPC: G02B27/22
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To miniaturize and simplify a device and to prolong the life of the device by temporally changing the deflection angle of luminous flux by a deflection means and spatially moving an observed virtual image back and forth. SOLUTION: When the frequency of a sound wave applied from a transducer 23 is changed, a phase diffraction interval generated in an acoustooptical medium is changed and the diffracted light is deflected to perform scanning in an acoustooptical element 22. A controller 30 controls the driving frequency of the transducer 23 and changes the displayed picture on the CRT 31 synchronizing with the control thereof. When the driving frequency of the transducer 23 is made high to make the frequency of the sound wave high, the phase diffraction grating interval (pitch) becomes small and a diffraction angle (deflection angle) becomes large. When the deflection angle becomes large, the luminous flux to eyeballs 32 and 33 comes near to the inside and the picture is viewed in the distance by convergence. Meanwhile, when the frequency of the sound wave is made low, the pitch becomes rough and the deflection angle becomes small, and the luminous flux to the eyeballs 32 and 33 comes near to the outside and the picture is viewed nearby on the contrary.

Inventor: HIRATA TOSHITAKA
IPC: G05D3/12
Filed: 1981-10-20
Abstract: PURPOSE:To allow the 2nd and succeeding printings to start accurately at the 1st printing start position, by providing a means of holding the energized phase of a pulse motor when the printing of the 1st line starts. CONSTITUTION:In print mode, a phase switching pulse CP is inputted to a pulse distributor 9 and every time one CP is inputted, outputs to a motor driver 10 are changed. For the printing of the 1st line, a sensor 4 generates an output signal START and a phase holder 12 holds the phase of a signal applied to a pulse motor. For the printing of the 2nd and succeeding lines, the held phase is compared with the phase of the output of pulse distributor 9 by a phase comparator 13, which when both of them are in phase with each other, generates a coincidence detecting signal, allowing an AND gate 14 to generate a printing start output signal. Therefore, printed lines start invariably at the same position.

Title: Disk receiving case
Inventor: SONE SHOHEI
IPC: G11B23/033
Filed: 1988-07-06
Abstract: PURPOSE:To prevent fiber from being loosened out by arranging a non-woven fabric liner, for which a surrounding part is fused by a heated edge and died out, in the internal surface of a case. CONSTITUTION:A disk 2 is housed in a cassette 1 and a non-woven fabric liner 3 is adhered to the internal surface of the cassette 1. For this non-woven fabric liner 3, a surrounding part 31 is fused by the heated edge and thus, the binder resin of the non-woven fabric is fused only in the part of a cutting section. For the dieing-out by the heated edge, it is suitable for the mixed non- woven fabric of plastic fiber (polyester and polypropylene, etc.,) and rayon fiber especially. Then, by suitably keeping the temperature of the heated edge, the dieing-out can be executed without generating the burning of the rayon resin. Thus, the loosening-out of the fiber can be eliminated.

Title: Pulse generating circuit
Inventor: MISAWA HIDEO
IPC: H03K3/53
Filed: 1981-10-22
Abstract: PURPOSE:To prevent arc-through, by avoiding charging to a pulse forming circuit until a switching element is completely turned off after it turns on. CONSTITUTION:When a control trigger signal 20 is inputted to a main trigger circuit 21 and a trigger delay circuit 22, a main trigger signal is outputted from the main trigger circuit 21 to trigger a main switching element 19. The trigger delay circuit 22 outputs a control trigger signal with a delay ad drives a control trigger circuit 23. Thus, a charging trigger signal is outputted from the control trigger circuit 23 to the main trigger signal after a specified delay time. A switching element 13 for charging turns on with the charging trigger signal. Since a stable inverse biase can be given to the main swithcing element 19 until turning-off, the arc-through of the main switching element can be suppressed.
