Title: Guiding device for self-traveling work vehicle
Inventor: YOKOUCHI TAKESHI
IPC: G05D1/02
Filed: 1989-10-20
Abstract: PURPOSE:To attain the drive of a self-traveling work vehicle by burying intermittently many guide matters into the ground and providing the sensors at the front and back sides of the vehicle to detect the guide matters via at least one of both sensors. CONSTITUTION:Many magnets 6 serving as the guide matters are intermittently buried into the ground of a work area of a self-traveling mowing machine 1 along a traveling locus of the machine 1. A pair of magnetic sensors 7 and 8 are provided at the front side of the machine 1 with another pair of magnetic sensors 9 and 10 provided at the back side of the machine 1 respectively. These magnetic sensors detect the magnetism generated by those magnets 6. A guide controller 11 compares the results of detection with each other between the sensor 7 and 8 or 9 and 10 and at the same time outputs a control signal to a steering device 5. Then a control part 12 decides the signal of either one of those sensors 7 - 10 that actuates the controller 11. In such constitution, the machine 1 can be surely and automatically travel.

Title: Semiconductor device for incident position detection
Inventor: YAMAMOTO AKINAGA
IPC: H01L31/0248
Filed: 1987-10-29
Abstract: PURPOSE:To prevent a reduction in a detecting sensitivity by a method wherein a plurality of branch conducting layers formed in such a way that they are extended from a main conducting layer formed on a semiconductor substrate so as to connect a pair of position signal electrodes to the effective incident region only of the incident surface of the substrate are provided. CONSTITUTION:A pair of position signal electrodes 2a and 2b are provided on both end parts on the side of the shorter side of the incident surface of a semiconductor substrate 1 and a main conducting layer 3 is formed on the central part of the incident surface between these electrodes. Moreover, branch conducting layers 4 are formed on an effective incident region B only in such a way that they are extended from the layer 3 in the direction of the incident surface and these are formed into a plurality of layers at equal intervals to one another. Accordingly, as no branch conducting layer does not exist on a reactive incident region C, a probability that electron-hole pairs flow in the layer 3 is low even though the electron-hole pairs are generated here. Moreover, a P-N junction capacitance is also reduced by the amount of the branch conducting layers which are not provided. Thereby, a reduction in a detecting sensitivity can be prevented.

Title: Color picture reader
Inventor: MATSUOKA NOBUO
IPC: H04N1/40
Filed: 1990-10-12
Abstract: PURPOSE:To improve the S/N of picture signals by directly converting a color picture element amplitude output into digital data as a counter gate signal after the color picture element amplitude output is converted into a pulse width amplitude by means of linear lamp waves having a dynamic range corresponding to the color picture element amplitude. CONSTITUTION:When a white plate is read by means of a color linear image sensor 10, the color picture element amplitude output of the sensor 10 is supplied to an S/H circuit 42 through a buffer circuit 41 and converted into stable amplitude signals having different amplitude ranges at every color picture element. A linear lamp wave generating section makes the dynamic range of linear lamp waves which become a reference for comparison larger against the color picture element output having a large amplitude and smaller against the color picture output having a small amplitude. Therefore, the converted pulse width from a comparator 45 becomes uniform at the time of reading the white plate and the count value, namely, the digital data output becomes equivalent data having no color picture element amplitude difference.

Title: Optical fiber gyroscope
Inventor: TAKEUCHI YOSHINORI
IPC: G01C19/72
Filed: 1990-10-11
Abstract: PURPOSE:To make it possible to accomplish efficient mounting of a sensing coil and to make an optical-fiber gyroscope compact by forming the cross-sectional area of the sensing coil in a rectangular or square shape whose corners are rounded. CONSTITUTION:When a sensing coil 11 having the best possible sensitivity is to be mounted in a rectangular parallelopiped case 12, the largest cross-sectional area of the sensing coil is the one of a rectangular shape. When an optical fiber is curved in an extremely small radius, not only the transmission is strikingly increased, but also the fiber might be broken. To avoid this, it is recommendable that the cross-sectional shape of the sensing coil is made to be of rectangular or square shape whose corners are rounded. In this way, the sensing coil can be arranged along the inner surface of the rectangular parallelopiped case with the best possible uselessness.

Title: Fixing device
Inventor: OKABAYASHI EIJI
IPC: G03G15/20
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent oil from leaking outside of a fixing device, for preventing the oil from sneaking into an unintended mechanical part by providing, for instance, a releasing agent leakage preventing means for preventing leakage, that is, a releasing agent discharged from the respective discharge holes of a supplying nozzle from flowing down on the surface of the nozzle. SOLUTION: The supplying nozzle 43 is provided with a difference in bending step 70, in the base part on the side of a supplying port 66, of the nozzle 43, as the releasing agent leakage preventing means. Even if the whole of the fixing device is inclined to level or the nozzle 43 is inclined for some reason, in discharging the oil 44 from the discharge holes 68 provided in the surface of the nozzle 43, the oil 44 drops as a droplet. But, the oil remaining after the discharge flows downward on the surface of the nozzle 43, in comparison with the level case. The flowing down oil 44 reaches the part of the difference in bending level 70, but the oil 44 does not flow down more than that, so that the leakage of the oil to the outside of the fixing device never occurs.

Title: Speed controller for brushless motor
Inventor: OI SHINICHI
IPC: H02P6/12
Filed: 1991-09-26
Abstract: PURPOSE:To eliminate the occurrence of a surge caused by the abrupt fall of a square wave supplied to a rotary field coil when a brushless motor is rotated at an intermediate to low speed and, at the same time, to control the rotating speed of the motor by utilizing the abrupt attenuation of a square wave voltage by forming a triangular wave which gradually raises a voltage and attenuating the square wave voltage from a time when the voltage reaches a set voltage. CONSTITUTION:A triangular wave V2 is formed by inputting a square wave V1 outputted from a control circuit 9 to speed control circuits 8. When a speed setting voltage V3 is set at a low speed level A, a gate voltage V6 is gradually lowered by means of the time constant of the circuit 9 from a point of time T1, because the triangular wave V2 becomes larger from the voltage V3 at the point of time T1, and the effective value of the voltage V6 drops, resulting in the low rotating speed of a rotor 1. When the voltage setting voltage V3 is set to an intermediate speed level B, the gate voltage V6 gradually drops in a similar manner from a point of time T2 and the rotating speed of the rotor 1 becomes an intermediate speed. When the value V3 is set higher than the maximum voltage C of the triangular wave V2, the gate voltage V6 becomes a square wave and the rotor 1 is rotated at its maximum speed.
