Title: High hardness sintered material
Inventor: ISHIMATSU EIICHIROU
IPC: C22C29/14
Filed: 1981-07-23
Abstract: PURPOSE:To obtain a high hardness sintered body with enhanced strength by an ordinary sintering method by sintering a press-molded body of a powdered mixture of metallic oxide with boron and one of Zr, Hf, V, Nb, Ta, Cr, Mo and W. CONSTITUTION:This sintered material is a sintered body consisting of 10- 95vol% metallic oxide and the balance one or Zn, Hf, Nb, Ta, Cr, Mo and W each having a high m.p. and B with inevitable impurities. The B is contained in >=0.01 volume ratio to the metallic oxide and bound as the boride of the high m.p. metal. Sintering is facilitated by the reaction of the metallic oxide with the B or B in the B compound, and the rearrangement of the grains and an increase in the density are caused at a relatively low temp. As the sintering proceeds, the high m.p. metal and the B contributing toward facilitating the sintering combine with each other and exist as boride among the metallic oxide grains, inhibiting the growth of the metallic oxide grains. Thus, a high density sintered body can be manufactured at an ordinary sintering temp.

Filed: 1985-05-29
Abstract: PURPOSE:To facilitate the counting of particulates by using ordorless and harmless propylene glycol which is small in consumption as the solvent of a particle size increasing means. CONSTITUTION:Laser light oscillated by a laser diode 2 is collimated by a lens 3, converged by a cylindrical lens 4 only in an X-axial direction, and focused on right before the nozzle 28 in a measurement chamber 6. Clean air after dust is removed by a filter 22, on the other hand, passes through a high- temperature saturated vapor chamber 23 wherein propylene glycol is heated and enters a mixing chamber 26 through a duct 25 as high-temperature saturated vapor. Further, aerosol containing particulates to be measured in a clean room, etc., is supplied to the mixing chamber 26 through a duct 27. The room- temperature aerosol and high-temperature saturated vapor are mixed in the mixing chamber and the vapor is condensed around particulates of the aerosol as cores to increase in particle size. When condensed cores spouted out of the nozzle 28 pass through the focus of the laser beam, the laser light is scattered and its scattered light is converged by condenser lenses 8 and 9 and converted into an electric signal by a photoelectric converter 10.

Title: Hydraulic control device
Inventor: TSUKIMOTO TOSHIAKI
IPC: F15B11/00
Filed: 1982-07-05
Abstract: PURPOSE:To make the easy addition of an attachment valve possible by a method wherein a pump is controlled by a pilot pressure prevailing between a pressure generating mechanism installed in the center bypass passage of a changeover valve, which is arranged at the lowest course of the stream from the pump, and a logic valve arranged in the upstream of said pressure generating mechanism. CONSTITUTION:In case that an attachment valve 23 is added, the delivery rate of a pump 2 is decreased by the pilot pressure in the upstream of a pressure generating mechanism 17, because the port 27 of a logic valve 20 is communicated to a tank and the logic valve is open under the conditions that changeover valves 8-10 and the attachment valve 23 are in their neutral positions respectively, while the delivery rate of the pump 2 is increased by changing-over the attachment valve 23, because the logic valve 20 is closed by said changing-over, resulting in lowering the pilot pressure. On the other hand, in case that the attachment valve is unnecessary, a poppet valve 30 and the like are removed from the logic valve 20 in order to extinguish the function of the logic valve 20 and only the pressure generating mechanism 17 is left at the back of the selector valve 10. The easy utilization of the attachment valve 23 is realized, because the mounting and dismounting of the logic valve 20 is easy.

IPC: G06F9/38
Filed: 1994-05-30
Abstract: PURPOSE: To shorten the access time by holding only a target selective branching address in a branch prediction buffer to enable a small buffer size. CONSTITUTION: When generating a prefetch error, in roder to confirm whether an instruction corresponding to a target address 46 can be used or not, a branch prediction buffer (BAB) 10 is checked. When these instructions can be used, these instructions are copied into any suitable buffer. Namely, when branching is already analyzed, they are copied into a sequential buffer 24 but when branching is not analyzed yet, they are copied into a target buffer 26. When the instructions corresponding to the target address 46 can not be used, these instructions are fetched from an I-cache(instruction cache) 34, copied into the sequential buffer 24 or the target buffer 26 and selectively arranged in the BAB 10. Thus, small buffer sizing is enabled and access time can be shortened.

Abstract: PURPOSE:To manufacture an alkaline manganese battery with improved voltage characteristics, by pouring an alkaline electrolyte containing manganate ions into the positive part of the battery. CONSTITUTION:In the process of manufacturing a battery, a liquid prepared by adding MnO4<2-> ions to an aqueous KOH solution or an aqueous NaOH solution which is usually used as an electrolyte, is poured into a positive mixture 3 contained in a positive case 1. A negative-side electrolyte is poured into a negative electrode 4.
