Title: Electromagnetic flowmeter
Inventor: MOCHIZUKI TSUTOMU
IPC: G01F1/60
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To eliminate infulgences of the change if a direct current offset voltage gederated when a shortcircuiting switch is turned on-off, by turning the shortcircuiting switch on/off in an excitation state and a non-excitation state and subtracting an output in the non-excitation state from an output in the excitation state. SOLUTION: A shortcircuiting switch S1 is provided between electrodes 2a, 2b and an earth electrode 2c. Outputs when the switch S1 us turned on and off in an excitation state and in a non-excitation state are obtained. The output in the excitation state includes a current signal and influences by 'change of a direct current offset voltage'. On the other hand, the output in the non- excitation state does not include a current signal, but includes only infulgences by the 'change of the direct current offset voltage'. The influences by the 'change of the direct current offset voltage' generated in accordance with the turning-on/off of the switch S1 are eliminated by subtracting the output in the non-excitation state from the output in the excitation state.  Even when the direct current offset voltage changes like an exponential function, the influences by the voltage are eliminated, so that correct measurements are carried out.

Title: Turn signal canceling device
Inventor: KAMEI HIROYUKI
IPC: B60Q1/40
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To permit an operating lever to be revolved by a simple constitution with part items reduced in number even when a cancel cam is at a cancel dead angle. SOLUTION: When an operating lever 21 is actuated so as to be revolved from its neutral position, a ratchet is hit against a cam projected part 13a, and when revolving force acts on a cancel cam lower 13 from the ratchet, since the cancel cam lower 13 is revolved so as to escape out of the ratchet, the actuation of the operating lever 21 can thereby be permitted. Concurrently, the bottom face of a recessed 13c is pressed by the tip end face of a projected part 12a, and the cancel cam lower 13 is lowered down against the energizing force of a cam spring 14. After that, when the ratchet is parted from the cancel cam lower 13, the cancel cam lower 13 is raised by means of the resiliency of the cam spring 14.  At this time, the bottom face of the recessed part 13c is pressed by the tip end face of the projected part 12a, and the cancel cam lower 13 is returned to the neutral position while being revolved.

Filed: 1992-02-26
Abstract: PURPOSE:To unnecessitate setting the compensation value of a display position at each display indication operation by deciding the compensation value of the display position from a display position compensation value table and displaying it at an optimum display position. CONSTITUTION:The size of a window is determined from display object data by calculating/processing the size of the window of display object data through the use of a calculation means 12.

Title: Supercooling inhibitor and preparation thereof
Inventor: WADA TAKAHIRO
IPC: C09K5/06
Filed: 1981-03-17
Abstract: PURPOSE: To prepare a supercooling inhibitor enabling the control of a solidifying behavior of a heat accumulating material, by covering the surface of a matrix for inhibiting the supercooling with the heat accumulating material.  
     CONSTITUTION: A mixture of a heat accumulating material (e.g. NaCH 3 COO. 3H 2 O) and a matrix for inhibiting the supercooling (e.g. Na 4 P 2 O 7 .10H 2 O) is heated above the melting point of the heat accumulating material, and then the precipitated matrix for inhibiting the supercooling is taken out and cooled. Thus, the surface of the matrix is covered with the heat accumulating material.  
     EFFECT: The supercooling inhibitor prevents surely the supercooling in the first cooling run as well as the subsequent runs, hardly allows the supercooling to occur and does not allow the heat accumulating material to solidify. Single crystals that were formerly considered to have an inferior supercooling inhibiting function can impart a supercooling inhibiting function equal or superior to that of the pulverized powder to the supercooling inhibitor.

Title: Apparatus for producing ozone water
Inventor: SUDA YUKIO
IPC: B01J19/10
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To produce ozone water efficiently by changing to-be-treated water into fine droplets in a mixing tank by using an ultrasonic oscillator and mixing them with introduced ozone gas. SOLUTION: In a mixing tank 6, introduced raw water, while being kept at a water supply level which optimizes the production of fine droplets by an ultrasonic oscillator 8 by water control valves 1, 2, 3 and a float (control of supplied water), is changed into the fine droplets by the oscillator 8 and released continuously into the tank. Ozone gas which was pressurized slightly and supplied from the valve 1 flings up the droplets which passed chiefly through the lower part of an agitation plate 16 and were released into the tank 6 to be dissolved in the droplets. The droplets, after being grown through mutual collision and aggregation by an aggregation apparatus 7, drop to be ozone water which is stored in the lower part.  Moreover, since the surface areas of water is increased equivalently by atomizing the water and mixing it with ozone gas, and ozone is dissolved into the water efficiently, a whole ozone water producing apparatus can be made small in size and light in weight.

Title: Controller for synchronous motor
Inventor: UCHIDA RIYOUHEI
IPC: H02P6/28
Filed: 1979-03-30
Abstract: PURPOSE:To control the motor with an extremely limited torque ripple by producing a current pattern in multi-phases employing a magneto-sensitive element for detecting the density of the magnetic flux. CONSTITUTION:As the density of two field system fluxes interlinked with two armature windings changes roughly in a sine wave following the rotation of the rotor, the output presenting a wave proportional to the sin wave at the output terminal of two magneto-sensitive elements. After added at the input stage of the pattern formation circuit 100, the output is applied to an amplifier 101 to produce the output VR. The waveheight of the output is invariably constant regardless of the rotational speed and variation of the load and the maximum and the minimum level developing at a cycle of electrical angle pi/2 is always fixed, where the relation of about 2<1/2>:1 is established between the two values. In addition, the processing of the output VR with a diode 104 and an amplifier 102 produces a constant output V equivalent to (2<1/2>+1)X(the minimum value of the output VR). The passage thereof through a differential amplifier 103 with the output VR forms a current pattern with a limited ripple.
