Title: Switch circuit
Inventor: MURAI KAZUHIRO
IPC: H03K17/30
Filed: 1979-09-22
Abstract: PURPOSE:To enable to detect two or more switches depressed at one time, by connecting a resistance between the base of the transistor and the power supply and connecting a plurality of series circuits of a resistance and a switch SW in parallel with the base and ground. CONSTITUTION:The collector of a pnp transistor TRQ is grounded via a resistor RL and also connected to the output terminal T0. The emitter of TRQ is connected to the power supply E via the Zener diode DZ, and the emitter is grounded via the bias resistance RE of the diode DZ. The base of TRQ is connected to the power supply E via the resistance R1, and further resistances R21... R2n are connected in parallel, which are respectively grounded via SW1... SWN. When all the SW1... SWN are on or an arbitrary switch is on, TRQ is off and the terminal T0 is at ground level and a given level can always be given to the terminals t1... tn corresponding to the SWs. If two or more switches SW1... SWN are simultaneously on, TRQ is ON, resulting that the voltage at the terminal T0 fluctuates, allowing to detect the depression of the SWs in error.

Title: Smoke removing apparatus
Inventor: OONO GENJI
IPC: B03C3/09
Filed: 1979-09-25
Abstract: PURPOSE: To prevent the smoke protecting effect from being lowered by providing a smoke inlet port in a smoke removing apparatus according to an electric dust collecting system so as to flow the polluted air stream in a condition avoiding said smoke discharge port to prevent a corona discharge electrode discharging only to one direction in a cylindrical flow passage from being polluted.  
     CONSTITUTION: Corona discharge is generated between a discharge electrode 4 and an opposed electrode 1 to rush said corona discharge to a direction of a corona ion electrode 1 and the corona wind generated from a protruded end 12 therewith is flowed to a direction except the vicinity of a side surface of the discharge electrode 4. The air containing smoke particles sent into from an open end 5 of a flow passage 2 is moved to the vicinity of the surface of the opposed electrode 1 to a direction as shown by an arrow 18 and receives the radiation of corona shower. The smoke particles are charged in a place extremely near to the electrode 1 and receives only one-sided corona wind from the protruded end and, because there is no air stream directing the protruded end 12 from the side of polluted air against the corona wind, said smoke particles are caught by the electrode 1 and not contained in the air in the vicinity of a side surface of the electrode 4. Therefore, the electrode is not polluted and, because charged smoke particles do not shield a discharge electric field, the smoke removing effect is high.

Title: Endoscope
Inventor: SHIBUYA SHOZO
IPC: A61B1/00
Filed: 1986-05-28
Abstract: PURPOSE:To prevent an optical system from being clouded by forming a rough surface for condensing vapor in an internal space into drops of dew on the wall surface in a main body at a part which does not contacts the optical path of the optical system. CONSTITUTION:The rough surface is formed of screw parts on the wall surface facing the internal space 25 at the part which does not contacts the optical axis of the observation optical system. Namely, screw parts 9d, 10b, and 15a are formed on the wall surface facing the internal space 25. Vapor is cooled by contacting the wall surface to become drops of dew, but the screw parts 9d, 10b, and 15a are large in surface area as compared with a plane and also contact the vapor widely, so the vapor is easy to stick and the majority of the vapor entering the internal space 25, therefore, become drops of dew at the screw parts 9d, 10b, and 15a, so that the temperature in the internal space 25 drops. Consequently, the vapor hardly becomes drops of vapor on the rear end surface of an ocular 14 and the front end surface of ocular cover glass 11 to prevent the optical system from being clouded, thereby securing an excellent visual field of observation.
