Title: Axial fan
Inventor: KANEBAYASHI SHINJI
IPC: F04D29/54
Filed: 1987-10-21
Abstract: PURPOSE:To contrive in reduction of noise in an axial fan by forming a casing inlet part into a trumpet cylindrical shape to be concentrically divided into two or more layers. CONSTITUTION:An axial fan comprises a motor 3, moving blades 2 driven by this motor 3 and a casing 1 enveloping the motor and the moving blade further fixing these motor and moving blades. The casing 1 is constituted forming its inlet part into a cylindrical trumpet shape 5 further to be concentrically divided into two or more layers. When the casing is thus formed, a flow generates no turbulence, coming in very well straightened. Thus almost eliminating the turbulence of the flow before it reaches the moving blade 2, the reduction of noise is contrived.

Title: Liquid crystal element
Inventor: MIHARA TADASHI
IPC: G02F1/137
Filed: 1986-11-11
Abstract: PURPOSE:To improve the intensity of transmitting light by arranging a polarizer on the basis of the axes of transmission and absorption of the polarizer at specific time so that the axis of transmission of the polarizer is rotated by an angle theta to a direction where the other stable state is brighter. CONSTITUTION:The stable state of one of two cells is made darkest and the axis of transmission is rotated on the basis of the axis of transmission of the polarizer at this time to the direction where the stale state of the other is brighter while the crossed nicols relation is maintained. When the axis of transmission of the polarizer is P1 (or P2), the stable state wherein the polarizer is in the P1 (or P2) direction is darkest and the maximum contrast is obtained, but the intensity of transmitted light is small. When the axis is rotated clockwise from the P1 or counterclockwise from the P2 (by 45 deg.-12 deg.), the maximum transmitted light intensity is obtained and the contrast ratio decreases. Further, when the axis is rotated exceeding said range, the transmitted light intensity decreases and the contrast becomes small. Thus, the axis is rotated by an angle theta<=45-theta' to obtain large transmitting light intensity without increasing the contrast so much.

Title: Purifying treatment of pool water
Inventor: KONO TOSHIMICHI
IPC: C02F1/76
Filed: 1988-10-22
Abstract: PURPOSE:To make pool water sanitary by promoting purification by always holding the concn. of residual chlorine to a set range by setting the change amount of a chlorine agent to a function wherein a set constant is added only when the measured concn. value of residual chlorine is reduced. CONSTITUTION:In the purifying treatment of pool water, the concn. of residual chlorine in pool water is measured and, in order to hold this measured value to a set range, the change amount of a chlorine agent (y) is increased or decreased on the basis of y=f(x)+a (wherein y is a charge amount of chlorine agent, x is the deviation of the measured concn. value of residual chlorine from the set range and a is a constant). However, only during a time when the measured concn. value of residual chlorine is reduced, the change amount of the chlorine agent is increased by a set value (b), that is, y=f(x)+a+b is set. During the reduction of residual chlorine, the bacteria or nitrogen compounds in pool water are on the way of the reaction with chlorine and require a greater amount of chlorine. By this method, a chlorine amount is always held to the set range to purify and sanitize pool water.

Abstract: PURPOSE: To compensate the defect of picture element in the vertical direction by providing an optical refractive means shifting an image by a prescribed amount in the vertical direction to an optical system so as to improve the utilizing efficiency of horizontal valid picture elements thereby enhancing the horizontal resolution. CONSTITUTION: A television camera 7 picks up the output image of an X-ray image intensifier 3 via an optical system 13 and provides the output of a video signal to a receiver 8. The magnification of the optical system 13 is set so that a circular output image from the intensifier 3 is inscribed with the short side of the valid detection plane of an image pickup element of the camera 7. Thus, the output image of the intensifier 3 is displayed on the receiver 8 in a range that upper and lower parts of the circular output image are missing when a variable apex angle prism 11 is not in operation. In order to pick up the missing image, a drive actuator for the prism 11 drives the prism in the vertical direction to refract the ray so as to shift the missing image onto a valid detection plane of the image pickup element of the camera 7.  Furthermore, the prism 11 is shifted by a required amount by varying a drive voltage for the actuator.

Title: Charging circuit
Inventor: YAMANAKA SUSUMU
IPC: H02J7/10
Filed: 1993-10-26
Abstract: PURPOSE:To shorten charging time by supplying a voltage higher than a specified voltage to a recharging cell, from the charge start up to a time when the charged voltage of the rechargeable cell becomes a specified value. CONSTITUTION:The output voltage of a constant-voltage power circuit at the time of charge operation start is V2 higher than a specified voltage V1, and with that voltage V2 charge operation is performed. Since the current is suppressed to I2 by the function of a constant-current circuit, the charge current begins to decrease if a charged capacity increases up to a specified value. The charging time at this time is represented as T1 here. After T1 charging is also performed by the voltage V2. If the charge operation continuous as it is, the charge current lowers down to I1. Then switching operation is performed at a charging time T2 by a voltage switching circuit, and the supply voltage becomes the specified voltage V1. As a result of the voltage lowering to the specified voltage V1 at the time T2, the charge current lowers and the charging finishes. These charging characteristics are shown by a dotted line in Fig. 2. Accordingly, it becomes possible to shorten the charge time, since current supply time is lengthened by T1-T0 by making the charge voltage higher than the specified voltage.
