Title: Diffraction grating and its production and wavelength conversion element
Inventor: MIZUUCHI KIMINORI
IPC: G02B5/18
Filed: 1993-06-21
Abstract: PURPOSE:To produce the diffraction grating with high efficiency at low loss by applying pulse voltages to a substrate having an electro-optical effect, thereby forming local electric field within this substrate. CONSTITUTION:Comb-shaped electrodes are formed on the front surface of the ferroelectric substrate 1 having the electro-optical effect and a plane electrode is formed on the rear surface and the pulse voltages of a high voltage are applied between both electrodes by a pulse power source 3, by which the impurity ions within the crystals are moved without generating dielectric destruction. The moved impurity ions form the local electric field within the crystals and formed local electric fields induce a change in the refractive index in the substrate 1 by the electro-optical effect. The change in the refractive index formed by the local electric fields is periodically formed if the electric fields are impressed by using the comb-shaped electrodes. The diffraction grating is formed by impressing 1kV to 100kV/mm electric fields between the comb- shaped electrodes and the plane electrode for 1musec to 1sec.

Title: Manufacture of hume concrete pipe
Inventor: WATANABE YOSHIHARU
IPC: B28B21/30
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To require no skill and shorten manufacturing time and further enable avoiding risks during an operation by charging concrete into a form which is rotated at a low velocity and cutting the concrete to he specified thickness and further, tightly solidifying the concrete by centrifugal molding, when a Hume concrete pipe is manufactured by reducing the generation of lime wash or preventing it from being generated. SOLUTION: Concrete is charged into a form to spread it over the entire length of a pipe while the form is rotated at such a low velocity that the concrete is allowed to stick flat to the inner wall of the form, and the excess thick concrete is removed at this point of time. For example, a steel bar of the same length as or longer than the length of the pipe or the like is pressed using the edge of both ends of the form, while the form is rotated at a low velocity and the excess concrete which is swollen to the side of the rotating direction is removed using a hooked bar or the like. Thus it is possible to manufacture a Hume concrete pipe of a specified thickness through molding at a single round of rapid rotation by cutting the excess concrete before initiating the centrifugal molding process.

Title: Constant delivery pressure pump
Inventor: KOBAYASHI KAZUNARI
IPC: F04D15/00
Filed: 1979-11-16
Abstract: PURPOSE: To keep a delivery pressure, which is set initially, in constant even if a flow quantity is changed from maximum to minimum by a method wherein a control system to change a characteristic of a pump by changing a clearance before vanes of an open impeller is utilized.  
     CONSTITUTION: If a clearance (a) of a vane 10 is relatively large during an operation of a pump, a performance of the pump is lowered as shown by a line S 4  in the characteristic chart and a delivery pressure becomes H 1  when a used quantity of water is Q 1  (operation point B). When the used quantity of water is increased into Q 2 , the pressure is reduced until a lower limit pressure H 2  (operation point C), pressure switches 56, 55 detect this pressure reduction and a valve 150 is opened while a valve 59 is closed. According to these operations, a pressure in a varied pressure chamber 39 is reduced and a piston 37 is moved forward to decrease the clearance (a). As a result, the performance is increased from S 4  to S 3  and the delivery pressure is increased (operation point D). Thus, according to this invention, a constant delivery pressure pump may be obtained simply and inexpensively only by a method wherein a structure of an ordinary single stage or two-stage centrifugal pump is changed slightly.
