Title: Main shaft rotation speed check system
Inventor: NOZAWA RIYOUICHIROU
IPC: G05B19/4062
Filed: 1981-05-14
Abstract: PURPOSE: To improve machining accuracy by installing captioned system to the NC machine tool which outputs an alarm signal when the rate of change in the main shaft rotation speed exceeds the range determined by the designated permissible percentage speed variation.  
     CONSTITUTION: When the command rotation speed is changed, a new rotation speed NC is set to the registor 105, a new speed command signal NVC becomes 1, the flip-flop 109 is reset, and the timer 107 simultaneously begins to count time. On the other hand, the arithmetic unit 106 performs computation to determine the percentage speed variation 7, and the comparator 108 compares this with the designated percentage speed variation q to determine which is larger. If η≤q is met after a certain period of time with the motor in normal operation, the comparator 108 outputs a signal of command speed attainment CVR and sets the FF109. Thereafter, the percentage speed variation η is compared with the maximum permissible percentage speed variation r by the comparator 110, and when η exceeds r, and alarm signal AL is outputted through the "and" gate 113.

Filed: 1987-03-27
Abstract: PURPOSE:To obtain an apparatus, by which the film growing rate is increased, on a wafer, by providing a heating part, which heats reacting gas that is blown through a dispersion head. CONSTITUTION:Reacting gas is blown on a wafer 3 through a dispersion head 1, and a film is formed on a wafer 3 in a normal pressure CVD apparatus.

Title: Satellite communication device
Inventor: ISHII KATSUYUKI
IPC: H04B7/005
Filed: 1982-04-27
Abstract: PURPOSE:To cancel the directional loss of a satellite antenna and to decrease the input variation level of a satellite repeater, by receiving its transmitted signal by the satellite repeater, and feeding part of the signal back to a transmitter through an additional device and controlling transmission electric power. CONSTITUTION:A feedback signal transmitted from its station and repeated by a satellite is divided into two by a distributor 11 and they are inputted to a level variation detecting circuit 12 and a variation component detecting circuit 13. The amount of variation detected by the circuit 12 is the total of the losses of an up and a down circuits due to the satellite antenna directional loss, so a reference voltage generating circuit 14 outputs a voltage corresponding to the amount of variation due to only the down circuit loss and a comparing circuit 16 outputs the amount of variation due to only the up circuit loss as an error voltage to perform reduction. Then, the circuit 13 detects the variation component of the satellite antenna directional loss and it is inputted to a variable delay circuit 17 through an inverting circuit 18. Then, a level adjusting device 19 is adjusted so the variation of the amount of attenuation of a variable attenuator is equal to the up circuit loss due to the satellite antenna directional loss.

Filed: 1982-04-29
Abstract: PURPOSE:To exchange Ca and Mg ions in hard water with ions in an additive to make soft water, while pasteurizing and decoloring said water at the same time, by charging the mixture of allophane extracted from volcanic eruptions or the like and humic acid in the hard water. CONSTITUTION:By charging the mixture of allophane extracted from volcanic eruptions or the like and humic acid in hard water, Ca<2+> and Mg<2+> in the hard water are exchanged with ions in said mixture so that allophane and the acid are changed into negative and positive ions, respectively in the water. As a result, the hard water is softened, pasteurized and decolored. For instance, by adding 0.3g of the mixture of allophane from volcanic eruptions or the like and humic acid to 1,000ml hard water of 400ppm and mixing it in the water, hard components in the water after the laps of 3min are made above 1ppm. Thus, soft water of good quality can be obtained.

Abstract: PURPOSE:To enable ICs to be mounted on both surfaces of a substrate by a method wherein an IC with a bump at high melting point is bonded onto the surface of both surface substrate while another IC with another bump at low melting point is bonded onto the rear surface of the substrate. CONSTITUTION:An IC 1 with a solder bump at the melting point exceeding 250 deg.C is reflow-bonded in N2 gas atmosphere. Successively, the upper substrate and the lower substrate are replaced with each other and then another IC 2 with another solder bump at the melting point not exceeding 200 deg.C is aligned. Then, the IC 2 is reflow-bonded in the atmosphere not exceeding 200 deg.C during the final process. At this time, in order to specifically control the atmospheric temperature, it is recommended to adopt VPS system as the reflow system. Through these procedures, the ICs 1, 2 can be mounted on both surfaces of the substrate by successively bonding the ICs 1, 2 from the IC 1 with the bump at higher melting point enabling the high density mounting to be attained.
