Title: Pipe coupling
Inventor: KOSHIJIMA JIRO
IPC: F16L37/12
Filed: 1992-04-23
Abstract: PURPOSE:To reduce the generation of water leak by installing a sealing member made of the material which possesses the water absorbing swelling performance, as for a one-touch type pipe coupling. CONSTITUTION:When a pipe 1 is inserted into a pipe coupling 2, the pipe 1 is inserted, spreading an O ring 10, and passes through a washer 11 and contacts the inner periphery of an O ring 12. In this state, the O ring 12 as sealing member 3 which is made of the material having the water absorbing swelling performance contacts the outer peripheral surface of a pipe and the inner peripheral surface of a pipe coupling body 6, and contacts water, and then absorbs water and is swollen, and the gap is perfectly filled, and 4 the contact area between the outer peripheral surface of the pipe 1 and the inner peripheral surface of the pipe coupling body 1 is increased, and also the contact pressure is increased by the swelling force, and the sealing performance is improved. When the pipe 1 is to be pulled out in this state or pulled out by the water pressure in the pipe, the O ring 12 forms a resistance for pulling-out, and the O ring 10 contacts an inclined surface 9 on the inner periphery of a bag shaped nut 8, and the inside diameter is reduced, and the ring 10 bites on the outer periphery of the pipe 1, which is prevented from being pulled out.

Title: Correlation flowmeter
Inventor: MISUMI KATSUO
IPC: G01F1/712
Filed: 1987-04-27
Abstract: PURPOSE:To enable the implementation of stable measurement, by calculating particles in a fluid as three-dimensional turbulence signals and by determining the mass flow rate of a powder substance based on the result of calculation. CONSTITUTION:A light-emitting element 41 and a photosensing element 51 are disposed in a pair as an optical sensor on the Y axis, and a plurality of particles are sensed as analog signals corresponding to the plurality. Multipliers 11 and 12 are provided for determining turbulence signals of a powder substance as three-dimensional ones from two-dimensional ones. Since the results of these multiplications are proportional to the density of the powder substance within a prescribed range, the average of the results of the multipliers in the upstream and the downstream is determined by an average computing unit 30, so as to obtain an exact density rho. A computing unit 20 determines cross-correlation on the basis of the result of the above computation, so as to obtain the velocity V of the powder fluid. Then, a mass flow rate rhoVA can be determined by conducting the multiplication of the density rho, the velocity V and the cross-sectional area of a flow tube by means of a computing circuit 40.

Abstract: PURPOSE:To keep a fuel injection velocity at the time of valve opening constant and make favorable fuel spray performable, by making an armature and a needle valve movable separately as well as making the needle valve possible to be opened with the fuel pressure that is given uniform pressure energy. CONSTITUTION:When a conductive coil 3 is excited, a grooved retainer 17 moves to the side of an opening part 21 against a spring 16 together with an armature 10, whereby a needle valve 12 comes off a valve seat against a spring 21 and comes into a state of being opened. In proportion as valve opening X of this needle valve 12 increases, force (f) of a balance spring 21 grows larger, and when its relation with fluid force F comes to F=f, movements of the neelde valve 12 are stopped. And, fuel is sprayed out of an opening part 8 passing through an annular clearance 25 and a grooved guide part 13 via an inlet 19 and a port 18. This spray velocity is not varied by the opening X of the needle valve 12 because pressure P1 inside a valve casing 1 is constant, thus such spray as being excellent in atomozation is securable.

Title: Pulse waveform conversion circuit
Inventor: TAKAYAMA TAKEYUKI
IPC: H03M1/82
Filed: 1989-04-25
Abstract: PURPOSE:To operate a circuit with a clock of 1/2 the one of an on-going PWM circuit in spite of forming an individual pulse wave-form symmetrically from side to side against a center by changing the number or width of the pulse corresponding to the value of an input digital signal. CONSTITUTION:The number of pulses in a pulse waveform conversion circuit is changed corresponding to the value of the input digital signal 1. Furthermore, no individual pulse width is set at a constant level, and it is changed corresponding to the value of the input digital signal 1. Therefore, at least one or more pairs of pulse waveforms having the same number of pulses surely exists. The number of pulses when the value of the input digital signal 1 is even-numbered differs from that when it is odd-numbered, and the interval of each pulse when the number of pulses exceeds two coincides with the cycle of a clock signal. By using such pulse waveform conversion circuit and pulse waveform output 11, it is possible to operate the circuit with the clock signal of 1/2 the one in the on-going PWM circuit in spite of forming the individual pulse waveform symmetrically from side to side against the center.

Filed: 1987-04-27
Abstract: PURPOSE:To prevent crack and deterioration of dampproofness of a package by installing more than one ring-shaped groove whose center is situated in the central part on the rear of the package. CONSTITUTION:A semiconductor chip 2 is installed on lead frames 3 which are connected by using bonding wires 4; this assembly is covered with a package resin 1 and a ring-shaped groove 5 is formed on the rear of the package resin 1. This groove 5 functions to easily discharge the moisture existing inside a package, especially near an interface between the lead frames 3 and the resin 1 to the outside as the water vapor during a heating operation of the package. For a large-sized package, a double ring-shaped groove 5 is formed. The ring- shaped groove 5 enables the inner moisture to be easily vaporized by the heat generated when especially a large-sized and large-volume package is mounted by a reflow method. It is possible to relax stress inside the package, to suppress a deformation of the rear of the package and to prevent deterioration of dampproofness.

Title: Data prepearing method for rough working
Inventor: SEKI MAKI
IPC: G05B19/4097
Filed: 1988-04-27
Abstract: PURPOSE:To prevent a boundary after worked from being disturbed in comparison with the boundary in a digitizing range by necessarily outputting the start point and end point of the point train paths of a going path and a returning path at the time of outputting NC data. CONSTITUTION:At the time of digitizing, identification codes are added to start points and end points (P1, P3, P11, P16, P18 and P23) of point train paths PLi(i=1, 2...) for respective going paths and/or returning paths. At the time of preparing the NC data for a rough working, when the fact that points for each m-number are outputted as NC data output points is designated, m-number of points are pre-read from the newest NC data output points, they are outputted without being thinned out when the points, to which the identification codes are added, exist, the m-th point is outputted as the NC data output point when the code does not exist, and thereafter, the same processing is repeated. Thus, the NC data can be prepared in which the boundary after worked cannot be disturbed in comparison with the boundary in the digitizing range.
