Title: Photographic device for photography with delicate color difference
Inventor: KASHIWAGI TOYOHIKO
IPC: H04N9/04
Filed: 1986-02-17
Abstract: PURPOSE:To photograph time variation with the spatial distribution of a specific material by splitting luminous flux from an object into two and inserting an optical filter which transmits only light with specific wavelength into the respective pieces of luminous flux. CONSTITUTION:A half-mirror or dichroic mirror is placed behind a photographic lens 1 to split the luminous flux into two. Relay lenses 4 and 5 are placed in the split pieces of luminous flux when necessary. Then, optical filters 6 and 7 which transmit only light within a specific wavelength range are interposed in front of image pickup tubes or image pickup elements 8 and 9. Then the optical filters 6 and 7 are so set as to transmit only light with 560nm and 577nm wavelength. An image pickup signal corresponding to the light with 560nm wavelength varies according to the oxygenation and deoxygenation of hemoglobin, but a signal corresponding to the light of 577nm is not affected. For the purpose, the signal of the image pickup tube corresponding to the 560nm wavelength is processed as a green signal and then variation of oxidized hemoglobin is projected as variation in green.

IPC: G03B21/14
Filed: 1987-02-16
Abstract: PURPOSE:To prevent a light emitting omission by detecting the light emission quantity of a xenon lamp, counting the number of times of non-light emission, when said quantity does not reach a prescribed value, and stopping the light emission, when its count value is larger than a prescribed value. CONSTITUTION:By controlling each of light emitting parts X1-X4 by a light emission control circuit 3, a light emission is executed in a short period. In this regard, filters F1-F3 are provided on the light emitting parts X1-X3 so as to obtain a specific coloring light. In such a state, the light emission quantity or the light emission intensity from the light emitting parts X1-X4 is detected by a photometric circuit 4, and subsequently, whether the detected light quantity is dropped from a prescribed value or not is decided by a deciding part 5. When said quantity is dropped, the number of times of detection of non-light emission is counted by counters C1-C4. Also, when it is decided by a deciding part 8 that a count value of non-light emission is larger than a prescribed value, the light emission is stopped. Accordingly, since a service life of a lamp is decided by comparing the light emission quantity of a xenon lamp with a prescribed value, a light emitting omission can be prevented.

Abstract: PURPOSE:To prevent fluctuation of output torque so as to prevent generation of vibration and noise by inputting an output signal of a control unit, based on each rotational speed, to each fuel injection valve and long/short adjusting a following fuel injection period by the fuel injection valve. CONSTITUTION:Each rotational speed of a crankshaft 57 at a crank angle almost equal to each other with the top dead center of each of cylinders 52 to 55 serving as a reference is detected by a control unit 61 and calculation- processed to output a signal. This output signal is input to a fuel injection valve 1 provided on each of cylinders 52 to 55, and each following fuel injection period is long/short adjusted. That is, the output signal of the control unit 61, when the rotational speed at a predetermined crank angle with the top dead center serving as the reference is slow, the following fuel injection period of the cylinder is lengthened so as to increase the rotational speed at the predetermined crank angle. On the other hand, the fuel injection period is shortened so as to reduce the rotational speed when it is fast. In this way, fluctuation of output is prevented by decreasing fluctuation of the rotational speed of the crankshaft 57.

IPC: G06F13/00
Filed: 1978-03-27
Abstract: PURPOSE: To carry out the data transfer of the different interfaces via the adaptor device performing the dialogue in duplication.  
     CONSTITUTION: The interruption given from interface 2 at the side of input/output device IO is decided at gate 91 and 92, and the transfer mode is memorized in FF93 and 94 each. The output of FF93 or 94 is delivered via gate 95 and then interrupted into interface 1 of the CPU side. While the END signal is delivered when the dialogue completes to be memorized in FF96 the data signal of interface 1 is lost. Then the data is held at the bus line via gate 97. When the END signal is received at FF98 and the dialogue comes to end also at interface 2, memory 96 is reset to complete the data transfer. Thus, the functions are shared for the firmware and the hardware, and the priority if given to the data transfer via the hardware to carry out the data transfer dialogue in duplication for the different interfaces. As a result, the IO of the different bus interface can be controlled.
