Filed: 1990-05-16
Abstract: PURPOSE:To adjust a level of a voice line automatically accurately by converting an output of a 2/4-wire changeover means connecting to an analog exchange and an output of an amplifier means into a digital signal, comparing a transmission and a reception level at 1st and 2nd pattern comparator means respectively, controlling an attenuation means and setting the voice level to a designated value. CONSTITUTION:An input signal from an analog converter is inputted to a 2/4W changeover means 10, its output level and an output level of a 1st amplifier means 31 are compared with a 1st pattern comparator means 51 and the difference is sent to an attenuation setting code conversion means 70.

Inventor: HOSHINO MASAMITSU
IPC: B65D33/38
Filed: 1994-04-28
Abstract: PURPOSE:To solve difficulties due to heat in opening a container without allowing food inside to stick to hand, make the container convenient in pouring out the contents with cleanliness being kept, and make the container disposable by a method wherein the inside of the container is formed with its upper part reduced gently while the contour is kept in conventional style and the front is also kept in conventional shape as occasion demands for design's sake. CONSTITUTION:The inside of the container is formed with its upper part reduced gently while the contour is kept in conventional style. If the design of the front is impaired because of the property of the contents, the front is kept in conventional shape. The size of an opening to be made on the reduced upper part must be such that allows the largest soild matter in food inside the container to pass smoothly therethrough. As for incisions, the depth can be made deeper than conventional one. As both ends on the upper part of the container can be held firm, food inside the container does not stick to hands when the upper part of the container is torne off from the incisions. Difficulties in opening due to heat can also be solved. Furthermore, the contents can be easily poured out, and the content do not stick to hands or other parts when the container is crushed up for throwing away.

Abstract: PURPOSE: To prevent expandable and contractible oscillation by having pressure receiving areas of a head side and a rod side or an area corresponding to the relative ratio of both areas, and making approach a difference between the product of head side pressure and a rod side area, and the product of rod side pressure and the head side area. CONSTITUTION: Respective pressure receiving areas of the end surface 31 and 32 of a shuttle spool 19 is set proportionally to the head side pressure receiving area and a rod side pressure receiving area of a hydraulic cylinder 14. When few expandable and contractible oscillation just after operating stop of the hydraulic cylinder 14 is converged, force of product of non load side oil chamber pressure acted on the end surface 31 and the pressure receiving area of the end surface 32 is nearly equalized with force of the product of load side oil chamber pressure acted on the end surface 32 and the pressure receiving area of the end surface 31. The balance of pressure acted on the end surface 31 and the end surface 32 is broken, force difference is generated.  Force is alternately on the end surface of an opposite side so as to offset against the force difference, and force approaches per alternate movement of the shuttle spool 19.

Title: Shaft sealing device for rotary machine
Inventor: ISHIKAWA KAZUHIRO
IPC: F16J15/40
Filed: 1980-09-16
Abstract: PURPOSE: To reduce consumption of shaft sealing liquid an the internal gas in a rotary machine by permitting the width of internal circumferential surface of the seal ring to change according to the pressure of the film of shaft sealing liquid and retaining a proper gap between the journal and seal ring.  
     CONSTITUTION: In the internal circumferential surface of a seal ring 6, an escape groove is excavated in such a way that its width reduces gradually from the upper flow side of rotation to the downflow side. According to this arrangement, the area to receive the pressure is narrow even though the liquid film pressure at the upper side of rotation is high, so that the force applied can be balanced with that at the downflow side. Accordingly, the balance of the liquid film pressure with the pressure of the spring 7 which presses the external circumference of the seal ring 6 toward the center of journal, is held on the condition that the displacement of the upper  flow side of rotation is identical to that of the downflow side, so that uniformity of  the gap between the journal 9 and seal ring 6 can be further enhanced.

Abstract: PURPOSE:To make the width in which noise is generated small, and also, to reduce the deterioration of a waveform by providing a first and a second delaying circuits, an adder, an attenuator, and a first subtractor, and obtaining a signal corresponding to second derivative. CONSTITUTION:A first delaying circuit 6 delays a signal containing noise by a prescribed time and outputs it, and a second delaying circuit 7 further delays the output of a first delaying circuit 6 by a prescribed time and outputs it. An adder 8 adds the signal containing noise and the output of a second delaying circuit 7 and outputs it, and an attenuator 9 attenuates the output of the adder 8 to 1/2 and outputs it. Subsequently, a first subtracter 10 subtracts the output of the attenuator 9 from the output of a first delaying circuit 6, outputs a signal corresponding to second derivative, and a limiter circuit 3 brings the output of the attenuator 9 to amplitude limit by a prescribed level. In such a way, width of a cut part brought to amplitude limit becomes smaller than the time when a first derivative signal is brought to amplitude limit by the limiter circuit, and the deterioration of a waveform is reduced.
