Title: Photosensitive body for electrophotograpy
Inventor: HANATANI YASUYUKI
IPC: G03G5/05
Filed: 1992-11-17
Abstract: PURPOSE:To provide a photosensitive body for electrophotography which is excellent in the characteristics of repetition by providing a photosensitive layer containing a hydroxysteroid compound. CONSTITUTION:A photosensitive layer containing at least an electric charge generating material and an electric charge transporting material on a conductive base. The photosensitive layer contains a hydroxysteroid compound. In this case, the hydroxysteroid compound is small in interaction with other photosensitive materials such as electric charge generating material and electric charge transporting material and is a compound which does not affect bad influence upon the characteristics of electrophotography and has the function of deactivating a radical species produced in the photosensitive layer by external attacking materials such as light and ozone and excels in ability of preventing a trap from being generated. Thus, with the addition of a hydroxysteroid compound, the lowering quantity of surface potential after repetition of 10000 times is suppressed, and also the deterioration of sensitivity shown at the exposure quantity reduced by half is reduced, so that its durability can be improved.

Title: Fuel reforming apparatus for fuel cell
Inventor: YOKOYAMA NAONOBU
IPC: H01M8/04
Filed: 1993-12-08
Abstract: PURPOSE:To stabilize the desulfurization reaction and operation of a fuel reforming apparatus by providing a temperature stabilizing means which detects the temperature alteration following abrupt change of mixed gas quantity at the inlet of a desulfurization apparatus and controls the flow rate of a gas which passes a bypass adjusting valve of a heat exchanger. CONSTITUTION:When the supply amount of a reformed gas F2 is increased sharply due to the abrupt increase of load, the temperature of preheated gas GH1 in the outlet side of a first heat exchanger 3 lowers. That is detected by a temperature detector 13 of a stabilizing means 10 put in the inlet side of a desulfurization apparatus 2 and a temperature adjusting apparatus 14 generates an output signal 14A of the difference from the set temperature 17S and a first bypass adjusting valve 11 is throttled based on the flow rate controlling signal 15S, which is based on the output signal 14S, of a flow rate controlling apparatus 15. Consequently, the flow rate Q1 of a mixed gas GH at low temperature decreases and the exchange quantity of the heat exchanger 3 increases, and thus the temperature lowering of the gas GH1 can be prevented. On the contrary when the gas F2 decreases abruptly, the exchange quantity of the heat exchanger 3 is lowered in order to suppress the excessive temperature rise in the outlet side.

Filed: 1988-12-06
Abstract: PURPOSE:To improve both measuring accuracy of densities in a deposit layer and accuracy of diameter ratio of the core to the clad by measuring the densities of plural parts in the radial direction of a fine glass particulate deposit layer. CONSTITUTION:A dehydrated and vitrified optical fiber preform substrate 4 consisting of a core (4A) and a clad (4B) is reciprocated in the shaft center direction in a vessel 1 while being rotated. The resultant fine glass particulate deposit layer 6 is then exposed to radiation emitted from a radiation source 9 through windows 11 and 12 so as to cross the deposit layer 6 in the radial direction. The radiation penetrated the deposit layer 6 is then detected with a detector 11 to measure densities of the respective positions in the radial direction of the deposit layer 6. The whole volume of the deposit layer 6 is determined from the densities and dimensions in the radial direction. The fine glass particles are deposited until the above-mentioned values attain a prescribed value.

Title: Cartridge for fixing anchor bolt and manufacture thereof
Inventor: SAKAMOTO MASAHIRO
IPC: E21D20/00
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To lessen the driving resistance of an anchor bolt and reduce the driving work time by uniformly dispersing a hardening viscous liquid resin, hardener particles made of a mixture of a binder resin and a hardener, and aggregate, in a breakable glass container. SOLUTION: A hardening viscous liquid resin 1 is filled in a glass container 5 and a hardener 2 and aggregate 3 are uniformly dispersed in the hardening viscous liquid resin 1, and then, the upper end 6 of the glass container is heat- sealed. The hardener 2 has a structure that a hardener whose hardening component is diluted by an inorganic material is confined in a hardening viscous liquid resin 1-insoluble binder resin. Since the hardening reaction is promoted when the hardener 2 is ground and the hardening component is dispersed into the liquid resin 1, it is not necessary to isolate the hardener 2 from the liquid resin 1 in separate containers. In this way, the driving resistance can be lessened and the driving work time can be shortened and hence, load of workers is reduced and the workability is improved.

Abstract: PURPOSE:To prevent the delay in the operation of an air bag at the time of a high speed collision by operating the air bag when the deformation speed from a deformation speed sensor is above a defined value while operating same based on the acceleration from an acceleration sensor when below the defined value. CONSTITUTION:At the time of the collision of a vehicle, when a deformation speed from a deformation speed sensor 14 is above a defined value (a), an air bag 16 is operated. When the deformation speed from the speed sensor 14 is below the defined value (a) while an acceleration from an acceleration sensor 12 at this time being above a defined value (b), the air bag 16 is operated. Next, as the acceleration from the acceleration sensor 12 is below the defined value (b), this time, the air bag 16 is not operated. Thus, the time required for the air bag 16 to operate when the deformation speed from the speed sensor 14 is above (a) is, e.g., 0-5m/sec. and, thus by making the time, e.g., below 5m/sec., the delay in operation of the air bag 16 can be prevented even at the time of collision at a high speed.

Abstract: PURPOSE:To reduce the sticking of dust, to facilitate cleaning and to decrease the influence of grids on the surface potential of a photosensitive body adjacent to it by cylindrically forming the grids of a electrifying mechanism of a scorotoron system and rotating it. CONSTITUTION:When the photosensitive body 16 is driven, a voltage is impressed on the corona charger 44 of an electrifying mechanism 18 and a prescribed electric charge is applied to the surface of the photosensitive body 16 through a rotary grid 40 by corona discharge. At this time, the dust on the grid affecting adversely the surface potential of the photosensitive body is hardly stuck to the grids since the grids rotates, and it can be scraped off by an easily attachable cleaning roller 50. Moreover, since the grids rotate, the surface potential can be perfectly prevented from being affected by the grids even when the grids 40 are brought 1 - 3mm close to the photosensitive body 16. In addition, the photosensitive body 16 is prevented from being contaminated by ozone generated from the corona charger 44.
