Title: Ion detector for mass analyzer
Inventor: MIMURA TADAO
IPC: H01J49/06
Filed: 1977-11-09
Abstract: PURPOSE: To remarkably reduce the production of the output signals, even if an ion detector is vibrated, by making an ion collector and a shield case at the same potential.  
     CONSTITUTION: An electrically insulating member 15 mechanically fixes a sheild case 2 to the end case of an analyzing tube 1, while electrically insulating the shield case 2, and a shiled case electrode 16 for guiding the potential of the case 2 to the outside extends through a portion of the insulating member 15. An ion collector electrode 11 is connected with the irreversible input terminal of an operational amplifier 14, the shieled case electrode 16 is connected with the output terminal of the amplifier 14, and the output terminal of the amplifier 14 is connected with the reversible input terminal and further with the input side of an amplifier 12. If the amplification of the amplifier 14 is infinite, it is considered that the output of an ion collector 3, i.e., the potential of an ion collector electrode 11 is equal to that of the electrode 16. Thus, the output of the ion collector 3 is neutralized with the floating capacity which is varied by the vibrations with the shield case 2.

Filed: 1987-05-30
Abstract: PURPOSE:To prevent overcharging and reduce the load of an engine by furnishing a light reduction sensor consisting of a photo-sensor which senses the light emitted from a optical fiber, and breaking the circuit of a power generator when the light reduction sensor has sensed completion of battery charge. CONSTITUTION:Existing invention includes a optical fiber 9 equipped with a sensing part 11, which is immersed in battery liquid 4 in a battery 1 and provided partially with a rough surface 10, and a light reduction sensor 8 which consists of a light source 15 for incidence of the light to the optical fiber 9 and a photo-sensor 16 to sense the beam of light emitted by the optical fiber 9. A switching element 20 to break the circuit of a power generator 6 when this light reduction sensor 8 has sensed completion of battery charge, is connected between the battery 1 and power generator 6. The light incident to the optical fiber 9 in conformity to the specific gravity of the battery liquid 4 leaks to inside the battery liquid 4 from the sensing part 11 of the optical fiber 9 to cause change of the amount of light, and the switching element 20 is turned off when the photo-sensor 16 senses this change in the amount of the light, to disconnect the power generator 6. This prevents overcharging to reduce the load on the engine, that should lead to improvement of the rate of fuel consumption.

Title: Sound insulating panel
Inventor: UMEOKA KAZUAKI
IPC: G10K11/16
Filed: 1989-05-26
Abstract: PURPOSE:To obtain the high-performance sound insulating panel of a light weight and thin type by connecting tubular bodies formed of a material having viscoelasticity approximately perpendicularly between surface plates in such a manner that the respective axial directions are approximately parallel with each other. CONSTITUTION:The tubular bodies formed of the material having the viscoelasticity are used as control elements 1 to control the phase speeds of sound waves and the plural control elements 1 are disposed in such a manner that the respective axial directions are approximately paralleled. The control elements 1 are so provided that the axis thereof and the planes of front and rear plates 2, 3 are approximately perpendicular to each other. The tube walls of the control elements 1 resonate and the phase speeds change largely when the sound waves pass the inside of the control elements 1; therefore, a difference is generated in the phase speed between the inside and outside of the panel. The sound waves are theoretically totally reflected when the difference increases to a certain incident angle or above and, therefore, the transmission energy is diminished and the sound insulating performance is obtd. over the entire part of frequencies. The high performance is obtd. with the light weight and the small thickness in this way.

Title: Fixing device cleaner for image forming device
Inventor: KUBOTA ISAO
IPC: G03G15/20
Filed: 1994-06-16
Abstract: PURPOSE:To effectively remove toner stuck to a roller. CONSTITUTION:When a medium 7 caring unfixed toner 8 is supplied to the fixing device, the medium 7 passes through the nip between a heating roller 4 and a pressure roller 5 following the rotation of the heating roller 4. At this time, the toner 8 is fixed on the medium 7 by heating with the heating roller 4 and pressurization with the rollers 4 and 5. After that, the offset toner stuck to the heating roller 4 is wiped off by a felt 2. Since a groove 3 is formed on a frame body 1, the pressurizing force of the felt 2 has strength and weakness in the rotational direction of the roller 4 and the reservoir of the toner is formed on the press-contact surface of the felt 2. Therefore, the toner stuck to the heating roller 4 is effectively removed without slipping from the felt 2.
