The gelled matrix prepared in this way is dried. A material based on Al 2 O 3 , Si 3 N 4 , BN, AlN, SiC, SiO 2 , etc., is used as the whisker. Then a dried matter is calcined at a sufficient temp. and for a sufficient time to transform the Al 2 O 3  to an α phase and the ZrO 2  to a tetragonal phase respectively. In this way, a composite powder consisting of the α-Al 2 O 3  and containing 2-30wt.%, preferably 4-16wt.%, tetragonal form finely dispersed ZrO 2  and 0-30wt.%, preferably 5-20wt.%, uniformly dispersed whisker, etc., is obtained.

Abstract: PURPOSE:To reduce vibration caused, for instance, at the time of starting compressors, by disposing two compressors such that the axes of rotation of the two compressors are aligned or in parallel with each other. CONSTITUTION:Two compressors 11a, 11b are of the same type and the same capacity, and they are stacked on each other on a base plate 12. Here, arrangement is such that the axes of rotation of the two compressors 11a, 11b are aligned with each other but the direction of rotation is opposite to each other. Further, the casings 13a, 13b of the compressors are coupled together rigidly at a coupling part 15. Since the direction of rotation of the two compessors 11a, 11b is opposite to each other and they are of the same type, the sum of torsional moments M1, M2 acted to a temporary casing 31 by the compressors 11a, 11b is reduced to zero. Therefore, the torsional moments acted to the temporary casing 31 are cancelled with each other.

A spool valve 6 is displaced leftward according to increase of the car speed to spread an opening area of the first variable throttle 30 and, on the other hand, to contract an opening area of the second variable throttle 32. Consequently, ratio of a pressure of oil, guided to a hydraulic reaction force chamber 28, is increased according to increase of the car speed. Further, the spool valve 6 receives a pressure of a peripheral groove 14c in a valve hole 4 as an area difference between large and small diameter land parts 6d, 6b thus moves rightward against an elastic member 8 to throttle the first variable throttle 30 and, on the other hand, to spread the second variable throttle 32, and the pressure in the peripheral groove 4c is suppressed. That is, pressure increase of the hydraulic reaction force chamber 28 is suppressed.

IPC: G21D3/04
Filed: 1983-03-07
Abstract: PURPOSE:To give an operator a positive operation guidance by employing hierarchical constitution which performs the function of a subsystem selection part again when an operation effect confirmation part corrects an operation effect evaluation model. CONSTITUTION:An operation selection part 6 fetches variation sign of a variable and a constant regarding the safety of a plant and the function state of a subsystem to determine a basic operation guide for securing the safety of the plant. The subsystem selection part 7 decides on the manipulated variable of the subsystem regarding the basic operation guide and its order on the basis of the extent of variation sign of the safety variable and constant. When a subsystem operation starts, the operation effect confirmation part 8 compares the measured value of response variation in safety variable and constant with the estimated value of response variation as to an operation effect evaluated model; when a correction of the evaluated model is requird, the response variation estimated value of the evaluated model is corrected by the measured value of the safety variable and constant. Then, the hierarchical constitution wherein the function of the selection part 7 is carried out in the correction is employed.

Title: Reciprocation device
Inventor: YOSHIDA HISASHI
IPC: F16H25/20
Filed: 1983-03-07
Abstract: PURPOSE:To make the stroke end of a reciprocation member adjustable at will, by screwing a pair of first engaging members into the reciprocation member, while setting up a second engaging member to be engaged with both the paired first engaging members to a frame. CONSTITUTION:When a solenoid 3 is excited, a plunger 4, a rod 5 and a shutter member 23 are all reciprocated toward the right. With this reciprocating motion, a stopper 15 for reciprocation use being locked to the specified position of the rod 5 comes into contact with the left end surface of a stopper 13 at the fixed side whereby the rod 5, the plunger 4 and the shutter member 23 stop their reciprocation. Under this stoppage, a dropping hole 24 of the shutter member 23 is well matched to the outlet of a second chute 22, and a particle 22a of the second chute 22 drops down to a particle receiver 26 by way of the dropping hole 24. Since the outlet of other side first chute 21 is closed by the shutter member 23, a particle 21a of the first chute 21 is not fed to the particle receiver 25 any longer. When the solenoid 3 is demagnetized, these plunger 4, rod 5 and shutter member 23 are all reciprocated toward the left by the energizing force of a return spring 17.

Filed: 1982-03-08
Abstract: PURPOSE:To suppress the generation of variation in the performance of a dry cell by securing an excellently close contact between a carbon bar and a positive mixture by melting a wax into the positive mixture, and carrying out a compulsory cooling after that. CONSTITUTION:A wax layer is formed on at least a surface of a carbon bar 5 which faces a positive mixture 3. After the carbon bar 5 is pressed and fitted into the positive mixture 3, the carbon bar 5 is heated so as to melt the wax into the positive mixture 3. After that, in a compulsory cooling process, the wax melted in the positive mixture 3 is completely solidified, and the carbon bar 5 and the positive mixture 3 are firmly fixed together by the solidified wax so that any looseness is prevented from developing due to mechaical shocks given to the carbon bar 5 in the following process. In thus manufactured dry cell, even when a contact shift is caused between the carbon bar 5 and the positive mixture 3 during the time when a sealing plate and a positive terminal plate 8 are attached to the carbon bar 5, the close contact between the carbon bar 5 and the positive mixture 3 is not deteriorated.
