Title: Ultrasonic probe
Inventor: ITOU TOSHIO
IPC: A61B8/00
Filed: 1982-01-30
Abstract: PURPOSE:To obtain a superior diagnostic image independently of the depth of a part of a subject, by optionally selecting the number of transducers to transmit ultrasonic pulse beams by a switching circuit and controlling the resonance frequency of the transducers. CONSTITUTION:Plural electric signal to acoustic wave transducers 12, 14, 16 consisting of a piezo-electric material ae successively laminated on a backing layer 10. Since the resonance frequency of each transducer is in inverse proportion to the thickness of the transducer, the frequency of ultrasonic pulse beams transmitted from the transducers can be controlled by applying excitation voltage between some of lead wires 10a-16a and selecting the number of transducers to be excited through the switching circuit 20. If the excitation voltage is applied between the lead wires 10a-16a, the thickness of the transducers is the sum of the thickness of three transducers and the obtained frequency is low one proper to the diagnosis of a deep part of the subject. Thus a superior diagnostic image can be obtained by selecting the frequency in accordance with the depth.

Title: High pressure pump
Inventor: MINAMI YOSHIO
IPC: F04B53/00
Filed: 1990-01-24
Abstract: PURPOSE:To prevent wear dust from being mixed with discharge fluid from a pump by providing a spill back line through which a part of fluid is discharged out at the discharge stroke of the pump, and thereby discharging wear dust which is produced during the discharge stroke, out of the pump through the spill back line. CONSTITUTION:Since fluid sucked in a pump 20 stirs the inside of a pump chamber (C) while wear dust adhered onto the surface of a planger 2 and wear dust which comes into the pump chamber (c) from the back face of a seal, are brought into a condition where they float in the fluid within the pump chamber (c). In this case, fluid is supplied to the pump chamber (c) through an over-flow line 32 during a suction stroke and a standby stroke, surplus fluid is discharged out of the pump 20 so that wear dust will never be mixed with discharge fluid. Furthermore, a spill back line 38 through which a part of fluid to be discharged out is discharged out of the pump, is provided for the discharge stroke of the pump 20, and the port of the line 38 is formed at a place close to a high pressure seal so that wear dust thereby flows into the line 38 before it comes up to a discharge port.

Abstract: PROBLEM TO BE SOLVED: To stably keep an arc by focusing three or more pieces of wires at the arc generating position and supplying three phase AC to at least three pieces of wires so as to generate the arc between at least two pieces of wires. SOLUTION: Angle positions of electricity supplying tips 20, 21, 22 are set so as to focus/cross the wires 70, 71, 72 on the extending line of a spouting pipe 6, i.e., on the extending line of the center axis of a mount 11. In this constitution, the arcs among three wires 70, 71, 72 with the three phase AC from the electric source 9 are repeatedly extinguished and reignited in order, but in any point of time, two or more arcs exist and since the wires 70, 71, 72 are acted as the electrodes in all pieces, the necessary temp. to discharge heat electron is held. Since ionized gas is always supplied from the neighbor arc, reignition of the arc is extremely smoothly executed. Even the flow rate of compressed gas is increased, the stable thermal-spraying can be continued without interrupting the arc.

Abstract: PURPOSE:To improve the response speed of the picking of a cell array by plotting the external frame of the cell array and picking by the overlap of the display area of this external frame and an area set by the coordinate value of the picking. CONSTITUTION:When a controller 3 reads display data from a display device 1 in order to display information on a display screen, a decision means 31 decides whether this information is the cell array or not.
