Title: Rotary engine
Inventor: JIYONASAN MAAKU ROOTAA
IPC: F01C19/04
Filed: 1990-02-13
Abstract: PURPOSE: To enable an apex seal to continuously maintain its enhanced sealability during operation of an internal combustion engine comprising a housing and a rotor which is movable in the housing and which is exposed to pressure of combustion gas. CONSTITUTION: An apex seal member 28 has a plurality of spaced openings 30 which extend through a member in a direction perpendicular to side walls 20, 22. Further, the openings 30 reduce the side area of the member 28 exposed to differential gas pressure, communicating a gas pressure on the one side of the member 28 with a gas pressure on the other side thereof so as to rapidly make the gas pressure uniform therebetween, and the frictional engagement between the member 28, and the side walls 20, 22 of a slot 18 is lowered. Then, each of the openings 30 accommodates a loose insert 32 which substantially fills in the volume of the opening 30 so as to reduce the volume upon which the gas pressure underneath the seal acts is reduced while the differential pressure causes the insert 32 to frictionally engage with the side wall 20 or 22.  However, even with the frictional engagement, since a clearance is present between the insert 32 and the opening 30, the member 28 can be radially moved with no hindrance.

Abstract: PURPOSE:To prevent a bulb base from being stained by adhesion of dust by mixing a certain amount of an electrification preventive agent made of one kind of an ester system substance, polyether system substance and an amide system substance into a polybutylene telephthalate/resin. CONSTITUTION:A bulb base is molded by using a thermoplastic resin, in which a very small amount of an electrification preventive agent made of an ester system, polyether system or amide system nonionic substance is mixed into a polybutylene telephtalate(PBT) resin. The amount of said mixture of not exceeding 0.5wt% shows no electrification preventive effect and even the adding not less than 6.0wt% does not change the preventive effect while when reaching 10wt%, molding properties of the PBT resin, for instance, fluidity grows and the molding mechanical properties change so that the mixing amount is limited to 0.5- 6.0wt%.

IPC: H04L27/18
Filed: 1984-02-24
Abstract: PURPOSE:To digitize all types of processing in a digital device together with miniaturization and cost reduction for said digital device connected to a digital network which performs communication with an analog device connected to an analog network, by omitting a process converting into the analog information. CONSTITUTION:An MODEM1 changes the phase of a fixed frequency such as 1,200Hz, 1,800Hz, 2,400Hz, etc. by an integer multiple as much as pi/4 to perform transmission/reception of data. While a digital network performs the sound communication with an analog network by a system where the coding is carried out with 8 bits over a communication circuit having a speed of 64kbit/sec. In such a case, the sampling speed of each frequency is set at 8,000Hz. Therefore, the sampling angle speed of the sine wave of each frequency is obtained by an equation I . Here the angles of sine waves having phases advanced every pi/4 are defined as theta0, theta1-. Then the sampling unit angle alpha is set at 2pi/40 to satisfy an equation II. Thus an equation III is obtained. Thus it is possible to obtain the digital signal value in response to the signal change of data as long as the digital values corresponding to sine waves of angles theta0(0), theta0(1), theta0(2)-theta0(39) are known.
