Title: Priority detecting circuit
Inventor: FUJIYAMA TOMOAKI
IPC: G06F9/46
Filed: 1990-03-08
Abstract: PURPOSE:To enable a high-speed processing by dividing input data into an (n) (n>1) pieces of partial data, independently exerting priority detection onto the respective partial data and totally controlling outputs according to the high-order or low-order information of the partial data. CONSTITUTION:The input data is divided into the (n) (n>1) pieces of partial data and priority detecting circuits 23-26 independently exert the priority detec tion onto the respective partial data. Then, circuits 19-22 are provided to detect whether priority exists in a certain digit more or less than the partial data or not. When the priority exists, in respect to the partial data at the digit larger or smaller than the digit, the result of priority detection is made ineffec tive and when the priority does not exists, in respective to the partial data at the digit smaller or larger than the partial data, the result of priority detec tion is made effective. Thus, the number of steps in the most adverse delay digit can be reduced and the high-speed processing is enabled.

Title: Vertical magnetic head
Inventor: SHIKAMA SHIGERU
IPC: G11B5/02
Filed: 1982-04-07
Abstract: PURPOSE:To eliminate a dip and prevent a waveform from getting out of shape, by putting an nonparallel tip part on the outside of a track at a reproducing time. CONSTITUTION:Since demerits of an unparallel head is due to a nonparallel tip part F, the tip part F is put on the outside of the track at a reproducing time. When the tip part F is put on the outside of the track, an output voltage 3'' outputted from the tip part F is flat and low, and therefore, the dip is eliminated almost. Further, the space loss is recovered. Th reason why the space loss is recovered is because an output voltage 3' outputted from a nonparallel part middle M is lower than said output voltage 3''.

Title: Hydrogen storage alloy electrode for alkaline storage battery
Inventor: KAMEOKA SEIJI
IPC: H01M4/24
Filed: 1989-03-10
Abstract: PURPOSE:To provide an alkaline storage battery having good cycle characteristics with less deterioration of characteristics in spite of achieving rapid charge/discharge cycles by using a mixture of metal oxide or metal hydroxide which exists as a metal at an electric potential where the hydrogen storage alloy absorbs and emits hydrogen electrochemically, in alkaline electrolyte with a hydrogen storage alloy for a main body. CONSTITUTION:Metal oxide or metal hydroxide to be mixed with hydrogen storage alloy is reduced in an electrode, and the hydrogen storage alloy absorbs and emits hydrogen electrochemically in alkaline electrolyte, so it exits as conductive material of a good conductivity in the electrode when a battery is operated. As a result, a contact resistance between grains of hydrogen absorption alloy becomes small, and the conductivity of the electrode of hydrogen storage alloy is increased, and a charge/discharge efficiency becomes high. For the metal oxide or metal hydroxide, CuO, Cu2O, Cu(OH)2, Ag2O, Ag2O2, PbO, Tl2O3, Tl(OH)3, AuO2, Au2O3,or Au(OH)3 can be used.

IPC: G03G5/06
Filed: 1983-04-06
Abstract: PURPOSE:To obtain a good toner image by incorporating a specified hydrazone type compd. CONSTITUTION:A photosensitive body contains a compd. represented by formula I in which R1, R2 are each optionally substd. alkyl, aralkyl, or aryl, but both are not alkyl at the same time, and R3, R4 are each H, halogen, alkyl, or alkoxy. Said compd. can be applied to all the types of photosensitive bodies using org. photoconductive compds., and above all, preferably used for the electrostatic charge transfer layer of the photosensitive layer functionally divided into the charge generating layer and the transfer layer, and the transfer layer is preferably formed on the generating layer. Said compd. itself has no film forming ability, so it is mixed with a binder resin to form the transfer layer. Such a hydrazone type compd. transfers positive holes to inject the holes produced from the generating layer to the transfer layer, then they reach the surface to neutralize negative charge and form an electrostatic charged image, and a good toner image is formed on the surface of the photosensitive body with a positively charged developer. Such a photosensitive body is good in sensitivity, low in residual potential, small in its change even after repeated uses, and it can be used for not only copying machines but widely for laser printers, etc.

Title: Incinerator and method of igniting radioactive waste material
Inventor: KANDA MASANORI
IPC: G21F9/32
Filed: 1990-03-09
Abstract: PURPOSE:To provide a superior igniting characteristic capable of increasing a mixed combustion ratio with substances hardly ignited and reduce a capacity of an incinerator and a discharged gas processing facility by a method wherein a main body of an incinerator for igniting waste material is provided with an oxygen rich air supplying facility for supplying air having a specified oxygen concentration as combustion air and remained combustion air and with a steam injection facility for injecting or atomizing water against a combustion part. CONSTITUTION:In this type of incinerator, air having an oxygen concentration of 25 to 40% is supplied as combustion air to a main body 1 of an incinerator by a rich oxygen supplying facility 2. Combustion speed of decomposed gas and soot in their gaseous phases generated when an easy-to-burn substance and a hard-to-burn substance in the radioactive waste material are ignited together is increased in proportion to oxygen concentration and then an igniting characteristic can be improved. In addition, it is possible to decrease the amount of waste gas. Water is atomized by a steam injection facility 5 against an igniting part, thereby a reduction in concentration of waste gas and adhesion of ignited and melted substance against the wall of an incinerator are prevented. Average supplying amount may be set at about 1/10 of the amount of combustion air. In this way, the combustion is carried out while a temperature of waste gas is being controlled to a value less than 1,000 deg.C.
