Patent JP-S62112922-A (JP)
Title: Safety device of burner
Inventor: OKURA MICHITAKA
IPC: F23D5/04
Filed: 1985-11-09
Abstract: PURPOSE:To make it possible to quickly sense the abnormal combustion of a burner so as to stop the combustion by a structure wherein the other end of an oxygen sensor is faced outside the combustion flame zone during normal combustion at the upper inner part of a skeleton. CONSTITUTION:A fuel in an oil tank 12 is drawn up with a solenoid pump 11, jetted from a nozzle 8, ignited by the electric discharge at an electrode 9 and burnt after being mixed with an air sent from a blower 13. The flame red-heats a skeleton 2. The radiant heat radiates outside through a perforated tube 3. The hot air passes through the perforated tube 3 and further ascends to a convection blower 7 so as to be dissipated to the surroundings. Onto a cover 5 sealed on a combustion cylinder 4, an oxygen sensor 6, the other end 6'' of which is faced outside the combustion flame zone A at the upper inner part of the skeleton 2 is mounted. Because the tip of combustion flame and the other end 6'' do not touch each other during normal combustion and oxygen exists in the surroundings of the end 6'', the voltage as low as only 1-2mmV develops in the sensor 6. However, if the flame extends due to abnormal combustion so as to envelope the tip of the sensor 6, almost no oxygen exists in the surrounds of the end 6'' and the voltage as high as about 50mmV develops in the sensor 6. Accordingly, the change of the voltage as mentioned just above is transmitted to a combustion control device 10 in order to stop the combustion.

Title: Control device for elevator
Inventor: WATANABE HIDENORI
IPC: B66B1/06
Filed: 1988-10-05
Abstract: PURPOSE:To minimize the ampere contract of distribution line in a home elevator and the like by providing a DC-DC converter for changing a storage battery with electric power generated from a solar battery when the elevator stops. CONSTITUTION:When an elevator stops, a control device does not control a converter by pulse width control, but switches a transistor on/off by extremely rapid repeating actions as a chopper. When the transistor is switched on, the current is flows through a solar battery 13 - a diode 12 - a normally closed contact 1c - a reactor 2a - a transistor 4c - a diode 5d - a reactor 2b - a solar battery 13 in the state of a closed loop, and electric energy is stored in the reactors 2a, 2b. When the transistor is switched off, the stored electric energy passes through the diodes 5a, 5d and is migrated to a storage battery 6. At this time, an inverter 7 in the closed state and the transistor 4c acts as a booster chopper so as to enable to take out the current from the solar batter 13 continuously.

Filed: 1991-09-30
Abstract: PURPOSE:To obtain large output and to reduce a non-linear error at the time of large input by constituting a bridge circuit by combining Ptype and N-type polycrystalline Si piezoelectric resistors formed in parallel to stress and arranging the longitudinal gauges of the piezoelectric resistors. CONSTITUTION:P-type polycrystalline Si piezoelectric resistors 4, 5 and N-type polycrystalline Si piezoelectric resistors 6, 7 are formed on a cantilevered beam part 2 in parallel to applied stress. When acceleration is applied to a substrate in the direction vertical to the main surface of the substrate, the stress in the longitudinal direction of the beam part is generated in the surface of the cantilevered beam part 2 as shown by an arrow 50 and, when the acceleration is applied downwardly, tensile stress is generated in the surface of the beam part. When this stress is applied, the resistance values of the P-type polycrystalline piezoelectric resistors 4, 5 increase and those of the N-type polycrystalline piezoelectric resistors 6, 7 decrease and a bridge circuit is constituted of those resistors to make it possible to obtain the large voltage output corresponding to the acceleration. By arranging the longitudinal gauge rates of the P-type and N-type piezoelectric resistors, a nonlinear error at the time of large input can be reduced.

Abstract: PURPOSE:To stop the working of numerical controller in a short time by using a specific calculation formula to the functional formula of the velocity value when the rotational speed of a servo motor is controlled based on the velocity value which is calculated as the function of the remaining count value after obtaining the remaining count value up to a stop point. CONSTITUTION:The formulas I and II are used to the functional formula of the velocity value when the rotational speed of a servo motor is controlled based on the velocity value obtained as the function of the remaining count value up to a stop point. In the formula I, the velocity value of an optional remaining count value set between points (a) and (b) is referred to as the velocitya-b, a constant 1 is set equal to the difference between the count value obtained between points (b) and (c) when the velocity changes from the point (b) in a curve b-c and the count value obtained between points (b) and (e) when the velocity changes from the point (b) in a straight line b-e, and a constant 2 is defined as a ratio between the velocity value and the calculation value. In the formula II, the velocity value of an optional count value obtained between points (b) and (c) is referred to as the velocityb-c together with n = 3/4 - 0.9 defined, and a constant 3 is equal to the value obtained by approximating the acceleration and the velocity obtained from formulas I and II at the point (b). Thus the stopping time can be shortened for a numerical controller.

As a result, the responsibility of a power piston lid of the brake fluid pressure generating device 10 is improved compared with conventional brake control devices using atmospheric pressure for negative pressure, because the fluid pressure is used instead of the atmospheric pressure. Since the fluid pressure generated in the brake fluid pressure generating device 10 can be linearly controlled in response to the travelling condition of the vehicle, the generated fluid pressure can be smoothly boosted up to a specified value.
