Title: Analysis of gaseous ammonia
Inventor: TAKADA NORIO
IPC: G01N31/00
Filed: 1984-07-05
Abstract: PURPOSE:To improve analysis accuracy and to measure exactly the gaseous ammonia in which sulfur dioxide coexists by distilling once a gas absorbing liquid as it is without analyzing the same and removing SO3<2-> in the liquid. CONSTITUTION:20% Sodium hydroxide is dropped through a glass tube from a funnel 2 to, for example, an Erlenmeyer flask 1 contg. the gas absorbing liquid A to make the liquid A alkaline. An Erlenmeyer flask 5 contg. 50-70%ml, 0.5% boric acid is put into a cooling vessel 6 and the flasks 1 and 5 are connected by a connecting tube 4. The flask 1 is placed on a heater 3 and the liquid A is boiled to absorb the ammonia in the liquid to the absorbent liquid B in the flask 5 together with water vapor. The liquid B contg. the distillate thereof is subjected to ammonia analysis by an indophenol method. The analysis accuracy is thus improved and the exact measurement of the gaseous ammonia is made possible.

Title: Detector for power, acceleration, magnetism relating to three-dimensional direction
Inventor: OKADA KAZUHIRO
IPC: G01P15/18
Filed: 1991-05-14
Abstract: PURPOSE:To equalize detection sensitivity of X, Y, Z-axes directional components in an acceleration detector relating to three-dimensional direction, using a capacity device. CONSTITUTION:A fixed substrate 10 is fixed to a device box 40, and the periphery of a flexible substrate 20 is fixed to the device box 40. When acceleration works on a work 30, deformation is generated on the flexible substrate. Displacement is generated on a displacement substrate 81 as a result through a connection member 70. Capacity devices C1, C3, C5 are formed by fixed electrodes 11, 13, 15 formed on the under surface of the fixed substrate 10, as well as displacement electrodes 21, 23, 25 formed on the upper surface of the displacement substrate 81 in an opposed manner to the fixed electrodes. The acceleration in X-axis direction is detected by variation in the capacity values of the capacity devices C1, C3, while the acceleration in Z-axis direction is detected by the variation in the capacity value of the capacity device C5. The periphery of the displacement substrate 81 is tilted, while inter-electrode distance of C1 and C3, and inter-electrode distance of C5 are changed, and the detection sensitivity in each axial direction is thus adjusted.

Title: Detecting method of temperature
Inventor: MATSUDA YOSHIKAZU
IPC: G01J5/60
Filed: 1983-07-28
Abstract: PURPOSE:To detect a temperature even if an emissivity of an object is unknown by installing a reference radiator to an incident end of an optical fiber. CONSTITUTION:A reference radiator 3 is made to approach a temperature measuring object 10, a radiated heat energy is received by the reference radiator 3, and the reference radiator 3 which has received it radiates a heat energy of a temperature corresponding to the received energy. This energy is transmitted from an incident end 2 of an optical fiber 1 to an emitting end 4 and emitted from the emitting end 4. Subsequently, this energy is devided into an energy which is made incident on a filter 6 of a center wavelength lambda1 and an energy which is made incident on a filter 7 of a center wavelength lambda2 by a half mirror 5, and signals which have transmitted through the respective filters 6, 7 are inputted separately to optical-electric transducers 8, 9, and converted to electric signals V1, V2. Both of these signals are operated by a two color operating device, a ratio of both signals is derived, and from this ratio, a temperature of the measuring object is derived.

Title: Optical head
Inventor: ARAI RYUICHIRO
IPC: G11B7/09
Filed: 1986-06-16
Abstract: PURPOSE:To decrease parts of an optical head, to reduce an adjusting part, to make the optical head inexpensive, and to improve its reliability by placing a photodetector part in both ends of a prism and obtaining a tracking servo- signal, and obtaining a focusing servo-signal by a single photodetector for photodetecting a light beam which has passed through the prism. CONSTITUTION:A luminous flux which has been emitted by a semiconductor laser 1 is condensed to a recording disk 4, reflected thereby and follows the direction opposite to going, but when it comes to a part of a half mirror 2, it is deflected vertically against the direction of the semiconductor 1, and reaches a prism 7. By a shift of a spot 12 from an objective lens 3 and a track groove 13 on the recording disk 4, intensity of a light spot 12 on a photodetector part 8 is varied, therefore, by catching this variation, a tracking servo-signal is obtained. On the other hand, each half of a 0th-order diffracted light 11 of the remaining luminous flux reaches a photodetector 9. In this case, a light spot on the photodetector 9 is varied in accordance with whether the objective lens 3 and the recording disk 4 are far or near, therefore, by catching this variation, a focusing servo-signal is obtained.

Title: Circuit for driving switched reluctance motor
Inventor: ASHIKAGA TADASHI
IPC: H02P25/08
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To remove the switching loss and also, reduce the anti-drive torque. SOLUTION: The rotor of a switched reluctance motor rotates by circulation currents in order to windings 2a-2c by turning on main switching elements Ta-Tc in order. The charge property of a capacitor CR for resonance is made into reverse property by turning on the switching element Tr for resonance prior to opening the switching element bodies Ta-Tc, and then, the switching element Tr for resonance is opened to regenerate the current by the accumulative energy in the reactor Lr for resonance in a DC power source E. By doing it that way, the voltage to be applied to the main switching elements Ta-Tc becomes zero, and at this time it opens the main switching elements Ta-Tc.  Moreover, the current by the energy of the winding decreases quickly by the resonance action of the resonance circuit by the winding and the capacitor Cr for resonance after opening of the main switching elements Ta-Tc, so the anti-drive torque becomes extremely small.

Abstract: PURPOSE: To improve driving sensation, by a method wherein a joint body is pivotably secured to a car body side so that it can freely rock vertically, and a cushioning motion of rear wheels is conducted like a swing arm on the whole in a manner to perform a rolling motion.  
     CONSTITUTION: Rear wheels 21 rock vertically centering around a whole point 8 functioning as a swing arm and a pin 12 acting as a fulcrum. The rocking is absorbed, damped, and cushioned by an axial rocking of a rear cushioning unit 13 placed between a joint body 9 and a rear frame part 2d. Rolling motion and a cushioning motion, produced by a vertical rocking, are conducted in combination. A relation of the joint body 9 to an intersection point P of an axis line N of a shaft 10 and a center  A of an axle 20 is set into a fixing state because the joint itself rocks vertically togetherwith the axle and the distance between the joint and the axle does not changes. As a result, the two rear wheels contact a ground in a stable manner, and the cushioning motion and the rolling motion are performed in a state that the two rear wheels contact a ground surface in a better manner.
