Title: Finned tube type heat exchanger
Inventor: KAMISAKA MITSUO
IPC: F28F1/32
Filed: 1978-10-17
Abstract: PURPOSE: To increase heat exchanging area of a finned tube type heat exchanger without decreasing the spacing between plate-like fins, by providing cylindrical projections on the surface of said plate-like fins.  
     CONSTITUTION: In a finned tube type heat exchanger consisting of heat transmitting tubes 201, ascending collars 202, plate-like fins 203 and cylindrical projections 204; said cylindrical projections 204 are formed on the plate-like fins 203 by way of press or other suitable method to extend perpendicularly to the surface of plate- like fin 203, i.e., in parallel with the heat transmitting tube 201, and height H of said cylindrical projections 204 is selected to be larger than the outer diameter D of the projection 204. With such an arrangement, gas flowing along the surface of fins 203 exchanges heat with liquid flowing in tube 201 by the aid of fins 203, projections 204 and ascending collars 202. Here, if the height H is selected to be larger than d 2 /4D where d is the inner diameter of projection 204, heat exchanging area is increased by providing such cylindrical projections 204, comparing with the arrangement in which no such projections 204 are not provided.

IPC: F16K3/28
Filed: 1994-05-02
Abstract: PURPOSE:To provide miniaturization further with a simple constitution, in a rotary type fluid opening/closing valve whose rotary torque is decreased and flow amount can be also adjusted. CONSTITUTION:An elastic material seal ring 5 is fitted to be inserted to an eccentric core part 4a of a rotary shaft 4 and brought into press contact with an internal side surface of a cylinder 2. A cylindrical body 1 is a cylindrical shape sealing both ends of the cylinder 2 with covers 3a, 3b, and by removing the upper cover 3a of the cylindrical body 1, inserting both ends of the rotary shaft 4 fitted to center holes 3a1, 3b1 of the upper/lower covers and by fixing the cover to the cylinder 2, a rotary type fluid opening/closing valve V is formed. Fluid circulating ports 2a, 2b are provided in a side wall of the cylinder 2. When the elastic material seal ring 5 is turned to press close one of the fluid circulating ports, a flow of fluid is closed. When the elastic material seal ring 5 is turned to perform no press closing, the fluid is allowed to flow. By turning a little the elastic material seal ring 5 from a completely closed condition, a flow amount of fluid can be controlled.

Title: Silicone oscillating pressure transmitter
Inventor: YOSHIOKA KENICHI
IPC: G01L9/00
Filed: 1990-05-17
Abstract: PURPOSE:To suppress the increment of the amount of sealing liquid and to improve temperature characteristic by housing a permanent magnet which generates a magnetic field in the inside of a body. CONSTITUTION:A semi-circular arc permanent magnet 40 is arranged by forming a groove part 39 in a nonmagnetic and cylindrical body 36, and the magnet 40 applies magnetic flux to an oscillator 31, and the oscillator 31 is coupled with an external self-oscillator via lead wire 25A, 25B, then, oscillates with proper number of oscillation. When standard pressure is applied to one side of a diaphragm 29 via a connecting hole 26 and a through hole 33, and measuring pressure P is applied to a wetted diaphragm 42, the pressure P is applied to the other side of the diaphragm 29 via the sealing liquid 46, which changes the proper number of oscillation of the oscillator 31. Thereby, the pressure P can be measured by measuring the change of the frequency of the oscillation, and since the permanent magnet 40 is located outside internal space 45, it is not required to provide a gap to absorb expansion due to the difference of temperature expansion coefficient between the body 36 and the permanent magnet 40 in the sealing liquid 46, which reduces the amount of sealing liquid and improves temperature stability.

Filed: 1977-10-28
Abstract: PURPOSE: To obtain an excellent picture by removing the unbalance of the luminous spectrum intensity of a fluorescent substance in each color, by adequately coloring the panel of a picture tube for filter effects.  
     CONSTITUTION: A substance obtained by adding Mn, Fe, Cr, etc., to a raw glass material by approximate 5% is colored in purplish red in comparison with normal glass, and the panel (face plate) is given chromaticity values x=0.291±0.04 and y=0.312±0.004; and at the spectral transmission rate in the visual-ray range, curve A shows the spectral transmission rate of normal panel glass, and curve B shows the spectral transmission rate of green in luminous wavelength range between 400 to 700nm adjusted in each wavelength. Therefore, this glass allows purplish-red light to pass through selectively, and covers that a normal red fluorescent substance is inferior in terms of luminous spectrum intensity to either green or blue bluorescent substance, thereby obtaining a color picture with hues which are extremely hard to appear.
