Title: Optical transmission system for irradiation environment
Inventor: ISHII KAZUHIKO
IPC: H04B10/00
Filed: 1982-02-12
Abstract: PURPOSE:To enable the monitoring of the partial irradiation of fibers by radiation and the monitoring of the abnormality in radiations to be generated by the rupture of process piping by combining all-quartz optical fibers and radiation resistant optical fibers in the same optical cable. CONSTITUTION:A laser diode 42 is subjected to pulse modulation directly by the pulse generator 43 of a fault point measuring device 4, and the light pulses which are made incident to an optical fiber 12a for monitoring through an optical fiber and an optical directional coupler 41 and propagate in the advance direction, cause Fresnel reflection at a fault point and return to the diode. The backward scattering light occurring in the Rayleigh scattering at each point returns also to the diode. When the optical fiber receives radiations, the backward scattering light decreases in proportion to the radiation dose. The reflected light is extracted with the coupler 41, and the relative output level of the backward scattering light with respect to distances is displayed as waveforms on a cathode ray tube 47 through a detector 44, an amplifier 45, and an averaging device 46, whereby the parts exposed to radiations as the composite optical cable including a radiation resistant optical fiber 11 and the dose thereof are monitored.

Title: Electric rotary machine
Inventor: ITOU MOTONARI
IPC: H02K3/493
Filed: 1978-02-24
Abstract: PURPOSE:To uniform the flux directing toward the supporting ring thus to prevent the deformation and the vibration due to the eddy current, by employing a wedge made of magnetic material in the stator slot at the portion facing with the supporting ring at the end of stator winding. CONSTITUTION:Stator slot wedge 9 at the portion facing with the supporting ring 14 for supporting the end of stator winding 12 where the length La of the stator core 11 is shorter than the length Lb of the stator core 3 is constructed such that the both ends are made of laminated iron plate 15 while the central section is made of an insulated member 16. With such structure a portion of the flux directing from the stator 1 toward the supporting ring 14 passes through the permeable section 15 in the slot wedge 9, to uniform the distribution of the flux thus to suppress the heat generation due to eddy current in the supporting ring 14 and to prevent the vibration caused by the thermal deformation.

Abstract: PROBLEM TO BE SOLVED: To exactly indicate complex motion of planet seen from the earth. SOLUTION: A dial 25 has a planet window 25a of nearly semicircle. A constellation plate 22 is a transparent disk rotating in accordance with the motion of stars. The ring shape planet plate 24 has pictures 24a and 24b of two planets 180 degrees apart. When the planets set in and is not seen in the sky, the pictures 24a and 24b of the planets can not be seen from the planet window 25a and the planet plate 24 does not rotate. From the time of planet 'rise', one of the pictures 24a or 24b of the planet is shown from the planet window 25 by rotating the planet plate 24 with the same speed as the planet plate 22 and the rotation of the planet plate 24 is stopped when the planets set in.  The complex motion of planets going back and forth in the constellation seen from the ground as the clay and hour goes on, is shown by the combination of rotation of the planet plate in one direction and stop.

Title: Power source amplifying circuit
Inventor: AOKI HIDEHIKO
IPC: H03F3/30
Filed: 1989-01-30
Abstract: PURPOSE:To prevent the generation of cross-over distortion and to suppress an idle current on an output stage by returning the output of an arithmetic circuit to a bias voltage stabilizing capacitor at the time of the forward/ backward feedback of the output. CONSTITUTION:Resistances R1 and R2, a diode Q1, and a capacitor CR constitute a bias voltage generating circuit, transistors(TR) Q2 and Q3 constitute a differen tial amplifying circuit on an input stage, TRs Q4 and Q6 constitute a driver stage, and TRs Q5 and Q7 constitute an SEPP output stage. A TR Q8, a resis tance R9, and TRs Q9 and Q10 constituting a current mirror circuit detect the current of the TR Q7, TRs Q11 to Q13 constitute the arithmetic circuit, which prepares a current IF in proportion to the square root of the product of currents I1 and I2 of the TRs Q7 and Q5, and the current corresponding to the output current IF of the arithmetic circuit is fed back to a capacitor CR so as to hold the current to an approximately constant value when the signals of the TRs Q5 and Q7 do not exist. Thus the idle current on the output stage can be suppressed to a small value without generating the cross-over distortion.

Abstract: PURPOSE:To attain high speed operation in the case of using an LSI with a small capacity and to reduce the power consumption of the LSI by varying a drive capability automatically depending on the size of load connected to the outside of the LSI. CONSTITUTION:With a voltage at an IN1 set to an L level, a transistor(TR) P12 is turned on and a TR N12 is turned off, an output of a gate G1 goes to an H level and an output of a gate G4 goes to an L level, then the TR N11 is turned off. When a load connecting to a terminal OT1 is heavy, since a sufficient H level is not outputted, an output of a gate G3 goes to an H level, an output of the gate G2 goes to an L level and the drive capability at the OT 1 to turn on a TR P11 is increased thereby increasing the level at the OT1 and outputting a sufficient H level.

Title: Facsimile equipment with electronic telephone directory
Inventor: SAKAMOTO TAKAHIRO
IPC: H04N1/00
Filed: 1990-01-31
Abstract: PURPOSE:To prevent malfunction due to simultaneous communication between plural cards and a main body by activating only a communication means of a loading section of a data memo card loaded at first when plural data memo cards are loaded sequentially to plural loading sections. CONSTITUTION:When a card 7 is loaded to a 2nd loading section 13, a detection switch 15 is closed, and since a card 7 is loaded already to a 1st loading section 8, a CPU 16 keeps an input to 3-input AND gates A1-A7 of the 2nd loading section 13 succeedingly to logical 0. Thus, a light emitting element of the card 7 of the 2nd loading section 13 is lighted and even when light is delivered to light receiving elements N1-N7, the information does not reach the CPU 16. Thus, only the loading section loaded with the card 7 at first is available for communication and the loading section loaded with the 2nd card 7 does not make communication. Thus, even when plural cards as electronic telephone directories are used, the loading space is available and malfunction is prevented.

The operating direction of moving contact points 84 is set to the direction (nearly horizontal direction) perpendicular to the vertical direction, while the first, second, and third relays 71-73 are installed on an outboard engine. When moving contact points 84 are applied with a shock in the vertical direction, a chattering action and a malfunction rarely occur. The performance can be stabilized, even when a hull hits water, after it has jumped by high waves.

Abstract: PROBLEM TO BE SOLVED: To make it easy to a use by warning a user of an error such as failure by making a detection means display an error condition until the error condition is corrected when the error condition is displayed on an image display unit on the basis of data outputted from an output means. SOLUTION: In the first step, a microcomputer 6 judges whether an error has occurred or not at various types of error sensors. If the answer is no, the process returns to the first step. If the answer is yes, in the second step, if there is no paper, for instance, 'No Paper' is displayed on a monitor television 3 in accordance with the error through a CRT control section 7, and in the third step, the microcomputer 6 judges whether various types of errors have been corrected or not. If the answer is no, the process returns to the third step. If the answer is yes, the process returns to the first step. Thus as any failure is known to the user immediately, the user can take an error correction measure immediately.
