IPC: G11C5/00
Filed: 1990-02-23
Abstract: PURPOSE:To prevent the careless consumption of a battery by connecting a discharge limiting analog switch between a battery voltage detecting terminal and a back-up battery. CONSTITUTION:The voltage of a back-up battery 11 is applied to an analog switch 9 via a resistance 10 and a diode 13. When a card is put into a device and a connector 7 is connected to the device, the power is supplied to a power detecting IC 8 and the switch 9 is turned on via a power detection signal line 17. Thus the voltage of the battery 11 is outputted to the connector 7 and read via a voltage detection signal line 16. If the power supply is cut off with the card kept in the device, the switch 9 is turned off by the IC 8 and the voltage of the battery 11 is not outputted to the connector 7 any more. Thus it is possible to prevent the careless consumption of the battery 11.

Abstract: PURPOSE:To slow down and stabilize the drying, heat cracking and combustion of a substance to be incinerated and permit the place of sedimentation of unburnt substance or the like to be limited to a specified place on the bed of the title furnace, by a method wherein a plurality of air dispersion tubes is arranged radially in the fluidized bed furnace so that the height of the positions of the tubes is different respectively. CONSTITUTION:A substance to be incinerated is thrown into a furnace through the supplying port 3 of the substance and fluidizing air (primary air) is supplied by injecting it from air dispersing tubes 6 into reserved sand to burn the substance while fluidizing it together with fluidizing medium. In this case, a height H2 from a central air dispersion tube group 7, provided radially in the furnace and consisting of a plurality of air dispersion tubes 6, to a bed is higher than the height H1 from the air dispersion tube group 8 at both ends of the furnace to the bed by a difference Hd, therefore, the circulating behavior of the fluidizing medium becomes strong at the center of the furnace. In this central part, contact and mixing between the fluidizing medium and the substance to be incinerated are improved, and drying, heat cracking and combustion of the mixture are quickened. The circulating behavior of the fluidizing medium show difference between at the central part and at the peripheral part of the furnace in such a manner; therefore, the drying, heat cracking and combustion of the substance to be incinerated may be slowed down and stabilized as a whole while unburnt substances, such as iron pieces, glass, stones or the like, may be collected to a place whereat the circulating behavior of the fluidizing medium is strong.

IPC: G05D1/02
Filed: 1990-02-22
Abstract: PURPOSE:To identify a scheduled light reflecting means without using a distance sensor by identifying the reflected light received from a scheduled reference point via the light received from another light source and based on the receiving time of a photodetecting signal when plural photodetecting signals are detected in the direction where the scheduled reference point should be detected in the next scan. CONSTITUTION:A means 241 is provided to detect the receiving time of a photodetecting signal together with the means 244 and 27 which estimate the receiving time and the azimuth of the reflected light received from a scheduled light reflecting means 6 in the next scan. A reference point identifying means 24 judges the photodetecting signal detected at the time closest to the estimated light receiving time as the reflected light received from the means 6. Then the receiving time of the reflected light detected in the next scan is previously obtained, and the reflected light received from the means 6 set at a reference point is discriminated from the light received from a light source except the means 6. Thus it is possible to eliminate the adverse influences given to the position detecting control of a self-traveling vehicle from a light reflecting object and a light source set in a work area or its periphery.

Title: Automatic leveling instrument
Inventor: FUKAMACHI YOSHIO
IPC: G01C5/02
Filed: 1981-03-23
Abstract: PURPOSE:To obtain an automatic leveling instrument of simple constitution free of an error in correction due to fluctuations of temperature by suspending a correcting reflective member, equipped with a reflective surface for upside-down inversion, on some point on an optical axis as a fulcrum in one body, and setting this fulcrum at a position a half as far as the focal length of an objective lens. CONSTITUTION:For example, an interval between a correction system 9 and an objective lens 4 is l1, an interval between the correction system 9 and a center point 2 of rotation for inclination is l2, and an interval between the correction system 9 and an index 7 is l3; and a main body slants around the point 2 by a fine angle alpha. In this case, the objective lens 4' is displaced downward by (l1-l2)alpha on the basis of an optical axis 1, and the correction system 9 is also displaced upward by l2alpha. Then, luminous flux which travels horizontally from the body to be collimated and strikes the objective lens 4' travels l1alpha lower than the optical axis 1 in parallel to the optical axis 1 to illuminate the correction system 9. Therefore, the luminous flux of collimation displaced downward by (l1+l2)alpha is incident to the correction system 9. On the other hand, the index 7 is displaced upward by (l2+l3)alpha on the basis of the optical axis 1, so correction meeting a requirement (l1+l2)alpha=(l2+l3)alpha, i.e. l1=l3 is achieved.

Filed: 1993-03-03
Abstract: PURPOSE:To allow driving of an induction motor at a highest efficiency point at all times by controlling the slip frequency for correcting the torque of the induction motor depending on a voltage command to be applied to the induction, motor. CONSTITUTION:A slip frequency signal 10 is initially set at a constant f0. The slip frequency 10 is shifted by a slight amount fX to a frequency f1 during an interval when a speed command signal 13 is shifted to a predetermined value which is sustained until the rotational speed of an induction motor 1 is sufficiently settled. Although r.p.m. of the induction motor 1 is varied to cause variation of a speed feedback signal 9, the speed feedback signal 9 is controlled to be identical with the speed command signal 13 so that the induction motor 1 has r.p.m. corresponding to the speed command signal 13. This constitution allows the induction motor to be driven at a highest efficiency point at all times.
