Title: Piston ring
Inventor: TSUCHIYA TAKESHI
IPC: C23C4/02
Filed: 1984-03-07
Abstract: PURPOSE:To prevent abnormal abrasion such as scuffing caused by sliding of a compound layer by removing a compound layer which is the upper layer portion of a nitriding layer and then plating or flame spraying a diffusion layer which is the lower layer portion thereof. CONSTITUTION:A nitriding layer 2 is disposed on the whole surface of a piston ring 1. As a compound layer 21 which is the upper layer portion of the nitriding layer 2 on the outer surface 11 of the piston ring 1 is not suitable for plating and flame spraying and not required, the compound layer is removed by polishing or the like, and then plating or flame spraying layer 3 is disposed on a diffusion layer 22 which is the lower layer portion of the compound layer 21.

Title: Semiconductor integrated circuit device
Inventor: TAKECHI MAKOTO
IPC: H03K19/0175
Filed: 1987-02-27
Abstract: PURPOSE:To increase an operating speed by adopting the hierarchy structure such that an internal bus line consists of plural sub bus lines connecting to output terminals of tri-state output buffers of a corresponding buffer group and of a main bus line connecting selectively to the sub bus lines. CONSTITUTION:The hierarchy structure is adopted for the internal bus line such that the bus line consists of plural sub bus lines SDB1-SDBm connecting to output terminals of tri-state output buffers of the corresponding buffer group and of a main bus line DB1 connecting selectively to the sub bus lines by dividing the plural tri-state output buffers BD1-BD6 are divided by a proper number as buffer groups. In connecting selectively a sub bus line to the main bus line, the load capacity of the main bus line is saved and the number of tri-state output buffers connected to the sub bus line is limited to limit the load capacity of each sub bus line, then the load to the tri-state output buffers is relieved so as to decrease the delay in the signal through the internal bus line thereby increasing the operating speed of the logic LSI.

Title: Manufacture of annealing separation agent for electromagnetic steel plate
Inventor: HIROMAE YOSHITAKA
IPC: C21D1/70
Filed: 1979-04-11
Abstract: PURPOSE:To produce an annealing separation agent which does not deteriorate the magnetic properties of an electromagnetic steel plate, by using a pulverizer comprising a pulverizing bowl made of porcelain and a rod to pulverize nonhydrated MgO into a prescribed grain diameter in a wet manner and then blending the pulverized MgO with limited quantities of Mg(OH)2 and an Al compound. CONSTITUTION:Unhydrated MgO is pulverized in a wet manner by a pulverizer, which comprises a pulverizing bowl made of porcelain and a rod, so that 70% or more of the grains of the pulverized MgO is 5mu or less in diameter. The pulverized substance is blended with 50% or less of Mg(OH)2 and 5% or less of an Al compound such as Al(OH)3 or Al(NO3)3. An annealing separation agent is thus produced. With this agent, the magnetic properties of an electromagnetic steel plate are not deteriorated in finish annealing. According to this method, iron which would deteriorate the magnetic properties does not mix into the agent as in the case that an iron-made bowl or rod is used, and the MgO can be pulverized in a short time as well as in dry pulverization.

Abstract: PURPOSE:To prepare a xonotlite-type calcium silicate having high crystallinity, by adding powdery lime material stepwise to a powder silicate material to effect the multi-stage batch-wise hydrothermal reaction, while specifying the ratio of CaO/SiO2 in the first-stage reaction. CONSTITUTION:A powdery silicate material is subjected to the hydrothermal reaction with a powdery lime material at a CaO/SiO2 molar ratio of 0.9-1.5.

Abstract: PROBLEM TO BE SOLVED: To reduce transmission torque so as to suppress increases in the amount of heat generation and a temperature by providing a relief valve opened when a hydraulic pressure generated by a hydraulic pump reaches a prescribed value for reducing a hydraulic pressure given to a clutch. SOLUTION: In a first valve element 91, since the slope of a first tapered surface 117 in a tapered surface 116 is small and the slope of a second tapered surface 118 is large, the discharge amount of hydraulic oil for the increase of a hydraulic pressure is set small in the case of the first tapered surface 117 and large in the case of the second tapered surface 118.

The tapered surface 116 is formed to be a multistage and thus more multistage characteristic is provided.
