Title: Making of single mode optical fiber of fluoride glass
Inventor: MARUKO BURAGURIA
IPC: G02B6/00
Filed: 1995-03-14
Abstract: PURPOSE: To efficiently obtain single mode optical fibers by preparing a tube comprising an external layer for a clad and an internal layer for a core made of a fluoride glass, making the internal layer thin by executing chemical etching in a specific quantity and then line-drawing.  
     CONSTITUTION: Molten glass constituent having a composition suitable to form the clad of single mode optical fibers made of a fluoride glass is poured into a mold 1 and then the mold 1 is rapidly rotated to form the external layer 2. After the external layer 2 solidifys, a molten glass constituent having a composition suitable to form the core is poured into a hole 3 in the external layer 2 and then the mold 1 is rotated to form the internal layer 4. Then, the internal layer 4 is made thinner by executing chemical etching at an ambient temp. until ratio of volume of the internal layer 4 to volume of the external layer 2 becomes equivalent to ratio of a core diameter to a clad diameter which is necessary for the single mode optical fiber. Then the obtained tube is line- drawn to obtain the single mode optical fibers made of a fluoride glass.

Title: Hydraulic automatic sluice
Inventor: ASAKURA SENKICHI
IPC: E02B7/40
Filed: 1985-04-15
Abstract: PURPOSE:To automatically close a sluice when the amount of water is increased by supplying excess water to a bucket by a method in which a bucket having a small hole in its bottom, serving as a gate, is attached to a bar whose intermediate portion is rotatably supported, and a weight is provided to the other end of the bar. CONSTITUTION:When the water level of a river is raised due to an increase in the amount of water, water flows into a bucket 1 serving as a gate through a water supply tube 4 from a water inlet 3. Hereupon, the water coming through a small hole 2 provided in the bottom of the bucket 1 partly flows out and most part is trapped in the bucket 1. For this reason, when the weight of water in the bucket 1 becomes heavier than a balancer weight 7, a bar 5 is turned around a rotary shaft 6, and the bucket 1 goes down. The water channel is closed by the gate 8 and the condition is kept insofar as the increase in the amount of water continues. Afterwards, when the water level is lowered, the inflow of water from the water inlet 3 is stopped and water in the bucket 1 is discharged from the hole 2, and therefore, the bucket 1 goes up by the action of the weight 7 to open the water channel.

Title: High performance wide angle lens
Inventor: NOZAWA TOSHIHIDE
IPC: G02B13/18
Filed: 1994-03-29
Abstract: PURPOSE:To make optical performance up to the periphery of a picture excellent with a small number of lens configurations and the lens configuration length short by using an aspherical surface for a first lens group and making the curvature of the image side surface larger than that of an object side in the negative direction in a fourth lens group. CONSTITUTION:This high performance wide angle lens is composed of a positive first lens group having the aspherical surface, a negative second lens group, a positive third lens group and a negative fourth lens group whose surface on the image surface side is a concave of a curvature larger than that of the surface of the object side in order therefrom. When the curvature of the object side surface of the fourth lens group is set smaller and the curvature of the surface image side is set larger in the negative direction, the fourth lens group has a shape near an aplanatic lens, so that the occurrence of a spherical aberration is rare but the occurrence of astigmatism and a distortion aberration is frequent. Since the aspherical surface whose negative refractive power is larger toward the periphery of a lens is used for the first lens group, the aberration occurring in the first lens group is the same as that occurring in the negative lens group, to correct the astigmatism and distortion aberration occurring in the forth lens group by the first lens group having the aspherical surface.

Title: Continuous contact gear pump
Inventor: HOTSUTA KOUJI
IPC: F04C2/20
Filed: 1983-05-10
Abstract: PURPOSE:To prevent force from being applied to the contact part of a tooth profile in a gear pump without causing any change of its delivery amount and pressure, by constituting the gear pump so that theoretical torque of a driving gear of always almost fixed level further theoretical torque of a driven gear of almost zero may be generated by the delivery pressure of fluid. CONSTITUTION:If assuming the volume dQ is delivered when a pair of gears O1, O2 having a number of teeth Z1, Z2 are rotated by the angles dtheta1, dtheta2, required energy for rotating the pair of gears is the power consumed for applying a pressure P to liquid of the volume dQ. Here the relation, where T1=CONSt (T1: rotating torque of the gear O1), T2=O (T2: rotating torque of the gear O2), is a hydrodynamic ideal condition of the gear pump, satisfying a condition of no pulsation without causing any change of the delivery amount and pressure. By this reason, the helix angle of a tooth profile multiplies integrally as against a pitch mpi (m = module) in a tooth width, causing the above condition to be attained.

Filed: 1980-06-16
Abstract: PURPOSE:To realize an easy replacement with a new prescribed card, by protruding the card to be replaced out of the prescribed array when a coincidence is obtained between the contents of the punched cards read out continuously and the indicated contents. CONSTITUTION:Card sets 8 that are stacked from the lower part in the normal sequence in a card hopper 7 are sent by one sheet to a card reading part 10. Thus the individual data is read by a reader 12 and stored into a card storing part 13 in the normal sequence. When the data of each read-out card coincides with the conditions given by the data applied through a command input device, an electromagnetic mechanism 14 works instantaneously by the signal pulse that is transmitted to push up the corresponding card to give a comparison and display to the difference of other dissident cards. In this case, the protruded card can be kept as it is since the cards are pressed en bloc by an elastic pressing means 20.

Title: Proportional control valve
Inventor: TAMECHIKA AKITO
IPC: F16K31/68
Filed: 1981-05-25
Abstract: PURPOSE:To improve thermal efficiency by connecting a rocker rod capable of rocking around a fixed fulcrum to a valve body, and connecting a movable member pressing the valve body to an intermediate portion of the rocker rod through a spring. CONSTITUTION:When the temperature of hot water is lower than the set temperature, a material enclosed in a thermoelement 6 shrinks, and if the movable member 19 is at its elevated position, movable fulcrums 28a, 28b of a spring 28 are above the horizontal level of a fixed fulcrum 24. Thus, the spring 28 raises the rocker rod 25 and the valve body 15 is at its elevated open position. The raised position of the valve is limited by the position of connecting portion 21 making contact with contact portion 22. When the temperature of hot water  rises, a material enclosed in a thermoelement 6 expands and the movable member 19 downs gradually. Consequently, the valve body 15 is pressed down, reducing the opening of valve little by little. As a result, the opening of the valve  body, is narrowed as the temperature of water in a hot water supply apparatus  2 is raised, consequently the size of flame of a burner 3 is reduced.
