Patent JP-H07318576-A (JP)
Title: Fluid sensing device
Inventor: TOOMASU EI HENDAASON
IPC: G01F1/075
Filed: 1995-05-02
Abstract: PURPOSE: To provide an equipment having reliability and durability capable of correctly monitoring modes necessary for a fluid moving under various environments, by providing a rotary member for transmitting light beams from an emitter to a detector via the fluid. CONSTITUTION: An emitter 14 serving as a single light source irradiates two light values 10, 12 arranged so as to allow the light to propagate along two different distance of the fluid. A single light detector 16 supplies signals that are relatively less afected by light source intensity, accumulation of substance on an optical surface and other factors. In order to change gaps in the fluid, the emitter 14 or the detector 16 includes a movable block 6 which requires no outside electric or other hookup (connection). Since a flow tube 3 requires neither O-ring nor such kind of seal so as to include the fluid perfectly, no mechanical liquid seal is required. In addition to measurement of light absorption of particles in the fluid and/or measurement of concentration of dispersed particles, flow measurement is carried out in compliance of intermittent period of light to the detector 16 from the emitter 14.

Title: Tape tension controller
Inventor: IMAI TOSHIO
IPC: G11B15/43
Filed: 1983-06-15
Abstract: PURPOSE:To eliminate the change in tape tension due to inclination of a base by providing an arm position correcting means for correcting the change in the relative position of a tension arm to the base because of the self-weight of the arm when the base is tilted from the horizontal state. CONSTITUTION:In the tape tension controller where a spring latch is provided at one end of a pendulum 22, when the base 1 is tilted, the pendulum 22 is rotated clockwise and the spring latch 6 is moved upward. As a result, a spring 5 is stretched and the tension of the spring 5 is increased. In setting the deflection of the pendulum 22 so that the moment with respect to a fulcrum pin 2 due to the increment of the tension is balanced with the moment of the fulcrum pin 2 by the self-weight W of the tension arm 3, the change in the tape tension due to the inclination of the base 1 is cancelled. In tilting the base 1 in the opposite direction, the pendulum 22 is turned rotated counter clockwise as shown in an altrernate long and short dash line, the length of the spring 5 is shrunk and the tension of the spring 5 is decreased. As a result, the tape tension change due to the inclination of the base 1 is cancelled.

Title: Lighting apparatus
Inventor: MARUYAMA TATSUO
IPC: G02B5/08
Filed: 1989-04-27
Abstract: PURPOSE:To obtain reflected light that provides prescribed light distribution and increase the luminosity of an apparatus through the use of diffused light with the resulting increased design quality by providing a reflecting surface formed by a visual field selection material which normally emits light rays incident at a set angle and diffuses light rays incident at any other angle. CONSTITUTION:A reflecting body 2, which is a solid of revolution, surrounds a light source 1, such as a high-brightness discharge lamp, and its opening portion is provided with a light control member, such as a baffle 3, which is a solid of revolution. The baffle 3 is formed by evaporation-coating Al, etc. on the rear surface of a non-light transmitting material, such as a metacrylic resin sheet, on which an additional protective layer is formed. Since the light from the light source 1, when reflected by the baffle 3, has an angle of incidence which is within an angle range over which the visual field selection material normally-reflects light, the light is reflected in a prescribed direction, making it possible to obtain prescribed light distribution. The reflected light from an object to be irradiated is diffusion-reflected by the baffle 3, causing it to shine in white, thus giving added brightness. Luminosity can be adjusted by changing the angle range over which the baffle 3 reflects light in diffusion.

Abstract: PURPOSE: To simplify the control and improve the stability at the time of change- over by stopping the closed loop control and performing open loop control when the minimum value of the output voltage of an exhaust sensor is more than the first predetermined value.  
     CONSTITUTION: The temperature characteristic of the output voltage VO of the exhaust sensor 7, is as shown in Figs. (a), (b) and (c) in correspondence to three states, that is, (a) a case where no blow-in of a current is performed, (b) a case where a low voltage is applied to perform the flow-in of a small current, and (c) a case where the flow-in of a high voltage is performed. In these figures, VR represents the value of the output voltage VO when the mixed air is excessively concentrated (rich), and VL represents the value of the output voltage VO when the mixed air is dilute (lean). With the lowering of the temperature, the value VL once rises up. Accordingly, a value VSL which is correspondent to the lower limit value T of the normal operating temperature, is determined, and when the minimum value of the output voltage VO, that is, VL, becomes more than VSL, the closed loop control is stopped, and changed over to the open loop control.
