Title: Detection system for failure of breaking
Inventor: TAGAMI YOSHIROU
IPC: H02H3/00
Filed: 1980-10-23
Abstract: PURPOSE:To detect the failure of breaking of a semiconductor breaking device in a high speed, by detecting that the circuit current is flowed when the interpole voltage of a main thyristor is absent. CONSTITUTION:The failure of commutation of a main thyristor 21, the failure of voltage stop or the failure of energy absorption of the main thyristor 21 or a surge absorber, a current circuit smaller than a commutating circuit current, etc. cause failures of breaking, and in any phenomenon of the failure of breaking, the circuit current is flowed under the state of no interpole voltage of the main thyristor 21. Consequently, the failure of breaking is detected in a high speed by AND among an output signal 32 (corresponding to breaking) due to a storage circuit 26 for a breaking command 31, an output signal 35 (corresponding to confirmation of the breaking operation time) due to a storage circuit 27 for the OR signal between a signal 33 of a detecting circuit 23 after the breaking command and a signal 34 of a reverse voltage detecting circuit 25 of an auxiliary thyristor 22, an inversion signal 36 (corresponding to no-voltage of the main thyristor) of the signal 33, and an output signal 37 (corresponding to presence of the circuit current).

Abstract: PURPOSE: To provide a device capable of recirculating a hydrogen gas directly from a cathode to an anode by providing a diaphragm of an ion penetration material, a cathode and anode means for vertically passing the hydrogen gas through therein, and a gas chamber. CONSTITUTION: A hydrogen gas generated in a cathode 18 passes through the cathode 18 in the vertical direction, and reaches an end portion 28 along a main longitudinal plane 26. Then the hydrogen gas passing through a gas chamber 32 is contacted with an end portion 22 of an anode 16 in the gas chamber 32, thus flowing through the anode 16 in the vertical direction along the main longitudinal plane 26 thereof. In this case, the hydrogen gas can be utilized for reaction in the anode 16, and therefore, the hydrogen gas from the cathode 18 is recirculated directly to the anode 16 for replenishing the hydrogen consumed during the electrochemical cell reaction.  With this constitution, a newly improved electrode device incorporated in an electrochemical system can be obtained, and consequently, this electrochemical system permits direct recirculation of the hydrogen gas from the cathode to the anode.

Title: Light guide
Inventor: YAMASHITA ZENJIRO
IPC: G09F13/04
Filed: 1986-06-25
Abstract: PURPOSE:To obtain illumination having no unevenness in intensity of illumination, by reflecting rays of light from light sources by means of a spherical reflecting surface and plane reflecting surface and leading the rays of light in a prescribed direction. CONSTITUTION:When rays of light from tubular light sources 4 and 5 are reflected in a wide angle by means of a spherical reflecting surface 2, the reflecting surface 2 receives the rays of light from the light sources 4 and 5 and rays of light which are totally reflected by a transparent plate 6. Therefore, it is considered that light source centers exist at the centers O1 and O2 of the light sources 4 and 5 and mirror images 4' and 5' and the rays of light which are regarded as those emitted from the center O1 in the directions A1 and A2 are reflected in the directions Am and An by the spherical reflecting surface 2. Moreover, rays of light which are directly projected on a plane reflecting surface 3 or those projected on the surface 3 after they are reflected by the surface 2 exist against the rays of light which are directly reflected toward the plate 6 from the surface 2, but those rays of light also advance toward the transparent plate 6 after they are reflected by the spherical reflecting surface 2 as shown by the light routes B1 Bm and B2 Bn. Therefore, illumination of uniform intensity of illumination can be obtained.
