Title: Optical signal selecting circuit
Inventor: TOGASHI MINORU
IPC: H04B10/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption by connecting the electric control input terminal of a j-th optical gate element to the connector of a j-th transistor and also connecting each emitter of plural transistors to a single power supply. SOLUTION: If a high level electric control input current is inputted to any one of electric control input terminal ICs and low level electric currents are inputted to other input terminals, optical signals are passed only through the gate circuit LGj into which a high level electric control input current is inputted. In the emitter coupled transistors Q1 to Qn, if a high level signal is supplied to the base of a transistor Qj and low level signals are supplied to the bases of the rest of transistors, only the transistor, to which a high level signal is supplied, is made conductive and other transistors are put into their shutting off conditions. Thus, by switching electric control input currents, optical signals are switched and electric control input currents are collectively adjusted.

Abstract: PURPOSE:To properly control exposure by computing detection signals from plural detecting means with weight corresponding to a weighting means and outputting the mean value or total value of arithmetic result as a density signal. CONSTITUTION:The weighting arithmetic circuit 51 executes an arithmetic operation to the density signals from respective sensors 16a... with the corresponding weight stored in a memory and outputs the means value or the total value of the arithmetic result to an automatic exposure circuit 40 as the density signal.

The reference voltage and an output voltage from a feedback transformer 34 are compared in a differential amplifier 37 and the voltage in accordance with the difference between both voltages is supplied to a trigger pulse generation circuit 44. The trigger pulse generation circuit 44 generates the trigger pulse synchronizing with the frequency of a power source 31 according to the output voltage inputted from the differential amplifier 37. The conduction angle of a thyristor 32 is controlled with the trigger pulse so as to control the effective value of the voltage impressed on both ends of an exposure lamp 8.

Title: Rotor for super conductive generator
Inventor: IWAMOTO MASATAMI
IPC: H02K55/04
Filed: 1978-12-29
Abstract: PURPOSE: To reduce vibration during the rotation with a less thermal contraction by integrating the normal temperature damper and the torque tube while specifying the ratio of the thickness between the two parts at a fixed value.  
     CONSTITUTION: The normal temperature damper 2 and the torque tube 1 are firmly integrated by welding or the like, while the thickness of the damper is set at more than twice as large as that of the tube 1. Generally, the yield strength of the metal material at a cryogenic level more than doubles that at the normal temperature. This case, it can be considered that the yield strength of the tube approximately under the cryogenic level with doubles that at the normal temperature. On the other hand, as the yield strength under the normal temperature is considered to remain unchanged, if it requirement as mentioned above is met, the proportion of the thermal stress becomes roughly constant with respect to the yield strength of the parts and therefore, both parts are almost equal in the tolerance in regard to the thermal stress design. The thermal stress works in such a manner as to contract the damper and tension the tube 1. Thermal constraction can be lessend with a construction easy to build, thereby reducing the vibration during the rotation.

Abstract: PURPOSE: To simplify the construction by connecting an arm to a slot of a connecting plate mounted to an eccentric shaft in such a manner as to be linked to a winding drum through a one-way cluctch while pulled in one direction with a spring.  
     CONSTITUTION: A connecting plate 3 is mounted to an eccentric shaft 2 which is rotated with a driving motor 1 and an arm 4 is connected to a slot 21 of the connecting plate 3 through a pin 22 in such a manner as to be connected to a winding drum 7 through one-way clutches 5 and 6 while pulled in one direction with a spring 9. As the driving motor 1 is driven, the winding drum 7 turns through the connecting plate 3 and the arm 4 to wind paper or the like. When the tension of the spring 9 equals that on the unwound side, the winding stops. This eliminates the need for engaging an detection arm or the like with material to be wound such as paper thereby simplifying the construction.

Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To simply and easily confirm the performance of a broadcasting device and the presence/absence of a fault in a crew cabin by receiving reference signal sound by the microphone of an emergency reporting device, returning it, confirming the broadcasting state of respective vehicles by a loud speaker and individually switching and further connecting the emergency reporting devices of the respective vehicles. SOLUTION: While an address SW is being pressed, address signals are inputted from an address circuit (A) through the contact point R34 of a relay R3 and transformers T3 and T4 to a passenger side address circuit (B). In the case that the sent-out address signals match with its own address of the passenger side, by operating a relay Rb, connecting a contact point Rb1 and operating a microphone amplifier A2, sound from the passenger side is outputted to the speaker on a crew side. Thus, since the emergency reporting device is accessed from the crew side, when reference signals are broadcasted in a broadcasting state and the prescribed emergency reporting device is accessed form the crew cabin, the broadcasting reference signals of an access destination can be listened to.
