Abstract: PURPOSE:To easily control lighting color, and enable a variable color illuminant and illumination device to be manufactured less expensively and easily by forming a layer having a photoelectric effect and an interference film comprising a dielectric multi-layer film on the surface of a base. CONSTITUTION:A photoelectric effect layer 4 comprising zinc oxide sandwiched with transparent electrodes 3 and 3', and an interference film 5 as the laminated multi-layer of titanium oxide and silicon oxide layers are formed on a glass tube 2 or a transparent resin plate 7 as a base. In addition, a transparent resin film 6 is laid as the uppermost layer for protection or electrical insulation. Also, a fluorescent bulb has a layer of a phosphor 1. Light incident on the interference film 5 changes the optical path thereof, due to the layer 4, and the interference wavelength thereof changes, thereby making possible illumination having a decorative effect. In this case, the variation of an optical path can be controlled with voltage applied to the electrodes 3 and 3', and variable color can be easily obtained. According to the aforesaid construction, a lamp and a lighting fixture of stable quality can be manufactured at low cost.

Title: Runaway prevention circuit of central processing unit
Inventor: KONISHI HITOSHI
IPC: G06F11/00
Filed: 1988-10-03
Abstract: PURPOSE:To prevent the increase of a circuit scale and to securely detect a runaway by outputting a runaway detection signal which is synchronized with synchronous communication to a signal line between central processing units and supervising the signal in a timer circuit for a prescribed period. CONSTITUTION:When synchronous communication is performed between the central processing units 1 and 2, the signal which has synchronized with the synchronous communication between respective central processing units 1 and 2, namely, the runaway detection signal, is generated, and the runaway detection signal from one central processing unit 1 is checked in the other central processing unit 2, whereby the runaway detection signal is outputted from the central processing unit 2. The signal is supervised in the timer circuit 3 for the prescribed period. When the central processing unit 1 has run away, the central processing unit 2 detects the runaway, and it prevents the occurrence of communication for the timer circuit 3. When the central processing unit 2 has run away, the timer circuit 3 counts up and resets a system since communication for the timer circuit 3 is prevented. Thus, circuit constitution can be miniaturized and the precision of runaway detection can be improved.

IPC: B01D59/34
Filed: 1988-10-03
Abstract: PURPOSE:To reduce the influence of Doppler effect on an isotope separating apparatus and to improve separating efficiency of the apparatus by providing a slit for passing vapor to above a raw material vessel, guiding the vapor stream to a direction perpendicular to an optical axis of laser beam and refluxing a metallic raw material vapor-deposited to the slit into the vessel. CONSTITUTION:In an apparatus for separating a specified isotope from the metallic raw material contg. plural kinds of isotopes, plural numbers of slits 7 for passing generated vapor stream 5 are provided to above a raw material vessel 1 so as to guide the vapor stream to the perpendicular direction against an optical axis of laser beam 6. At the same time, a refluxing device 8 where the metallic raw material vapor-deposited to the slit 7 is melted by heating, then refluxed to the raw material vessel, is provided integrally with the slit 7. By this constitution, generation of Doppler effect which changes the wavelength of highly precisely adjusted laser light is retarded since the laser beam contains no velocity component in the direction of optical axis, so shift of the wavelength of the laser beam is not caused. Thus, selective excitation of atom is proceeded effectively, and the isotope is separated.

The unstable surface 59 and operating surfaces 60, 61 jointed on a working surface 57 will make the installation of the working machine 1 unstable and its operation difficult, so that the surfaces other than the above surfaces are jointed unavoidably on the working surface 57. Consequently, the gas receiving port 26 is positioned on the top in the longitudinal or radial direction of the cylinder 23, thus preventing fluid 22a on the lower side of the cylinder 23 from going out of the cylinder 23 being left as it is.

Title: Color sensor circuit
Inventor: KOGURE YASUO
IPC: G01J3/51
Filed: 1988-09-30
Abstract: PURPOSE:To always keep constant resolution and to accomplish high speed decision by performing normalization for the change of the illuminance of a light source like analog. CONSTITUTION:The respective components of the output of resolved wavelength on a monitor side which is directly taken out from a light source 1 and the output of resolved wavelength on an object side taken out owing to the reflection, etc., on an object 9 are guided to logarithmic amplifiers LA1-LA6 and logarithmically converted to be outputted. The corresponding outputs of the components of resolved wavelength are respectively supplied to differential amplifiers DA1-DA3 so as to obtain the difference of logarithmic function. Since the difference is nothing but the logarithm of the ratio of the components of resolved wavelength, the normalization for the change of the illuminance of the light source can be performed. The normalization of the measured value for the change of the illuminance of the light source is all performed by an analog circuit, so that a deciding speed can be made remarkably high. The obtained value is logarithmically compressed, whereas the lowering of resolution can be prevented even if the illuminance of the light source decreases or the reflectance or the transmittivity of the object is low.
