Title: Magnetic guidance system for vehicle
Inventor: SATO SHUN
IPC: G05D1/02
Filed: 1989-03-16
Abstract: PURPOSE:To improve stability for the automatic travel of a vehicle by providing a single positional shift detecting coil, part of whose winding is interlinked with the spatial magnetic flux of a magnetism generating means and provided with three or more terminals at a magnetic sensor which detects the positional shift of the vehicle. CONSTITUTION:When the vehicle comes off a travel path and the magnetic sensor is deviated from the center of a magnetic marker 2, the distribution of the spatial magnetic flux from an excitation coil 4 becomes asymmetric in right and left directions, and the spatial magnetic flux phi from one end of the excitation coil 4 is interlinked to the windings L1 and L2 of the positional shift detecting coil 5, then, is collected to the magnetic marker 2. Meanwhile, the spatial magnetic flux phi' from the other end of the excitation coil 4 is collected to the magnetic marker 2 without being interlinked with the winding L2, and remaining spatial magnetic flux phi'' is also interlinked with the winding L1. As a result, the windings L1 and L2 induce an electromotive force corresponding to the change of the magnetic flux density of each of the spatial magnetic flux phi, phi', and phi'' to which each of the windings is interlinked, thereby, the aberration detecting signals can be generated between the terminals 52 and 54, and between 53 and 54. Thereby, the aberration detecting accuracy of the vehicle can be improved, and travel control for the vehicle can be performed with high accuracy.

Title: Centrifugal drier
Inventor: KOMAZAKI TAKU
IPC: H01L21/304
Filed: 1979-05-23
Abstract: PURPOSE:To automatically set up a carrier in centrifugal drying, by arranging a sample container on a rotary cage so that the container can be moved from a horizontal to a vertical postures by external manipulation. CONSTITUTION:An arm 6 is separated from a rotary cage 3. A container 4 is set in a vertical posture. A necessary dummy load 16 is put in the container. The cage 3 is rotated by a motor 2. Since substrates 9 are set in a horizontal posture, they are efficiently dried. Inertial rotation after the drying is detected by a photoelectric switch 12 and a light interception plate 11 attached to the shaft of the motor. When the rotational frequency of the cage falls enough and is index-detected, a control circuit 13 performs regulation 14 to stop the rotation. According to this method, the rotation is stopped into a fixed position without causing an impact. After that, the arm 6 is driven by another motor 8 through a gear 7 to thrust up the bottom of the container 4 into a horizontal posture. As a result, a carrier 10 is made horizontally portable. The apprehensions of contamination are thus decreased in the centrifugal drying.

Title: Probe for collecting molten steel fine particle for analysis
Inventor: ONO AKIHIRO
IPC: G01N33/20
Filed: 1989-03-15
Abstract: PURPOSE:To continuously supply a large amount of fine particles for a long period of time by a method wherein a terminal having unevenness and a large contact area is repeatedly immersed in and drawn up from molten steel and the molten steel adhered to the terminal is finely pulverized by an ultrasonic wave to be sent to an analyzer by argon gas. CONSTITUTION:A support cylindrical body 8 is driven downwardly by a lift apparatus and the lower opening part of a refractory cylindrical body 1 is immersed in molten steel to be analyzed and, subsequently, the downward driving of the cylindrical body 1 is stopped at a position where the uneven part 6a of a refractory terminal 6 is immersed in molten steel. Next, the terminal 6 is repeatedly immersed in and drawn up from the molten steel by the slight up-and-down movement of the cylindrical body 1 due to the lift apparatus and the rise and drop in the pressure of the argon gas supplied from a pipe 5. During this time, the ultrasonic wave from the ultrasonic vibrator in a case 2 is emitted from the port of the terminal and the molten steel adhered to the terminal 6 is finely pulverized to be guided to an analyzer by the flow of the argon gas to a pipe 7. By this method, a collecting probe generating fine particles of molten steel continuously for a long period of time is obtained.

Title: Driving circuit of planar display device
Inventor: WADA AKIHISA
IPC: H01J11/26
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To decrease a loss caused by a peaked current and to improve a recovery by a power recovery circuit in efficiency by changing over or varying coil inductance quantity while keeping electric charge and discharge quantity at a constant value. SOLUTION: When FET 1 is turned on, a voltage twice as high as a voltage of a condenser 8 can be induced on an inter-electrode capacity CP, and FET 5 is turned off and a current is made to flow only through a coil 9. When the FET 5 is turned on, a coil 11 comes in parallel with the coil 9; a total inductance is decreased; and a charging voltage rises steeply and approaches to a power source voltage VS. An inter-electrode capacity CP voltage is maintained at the power source voltage VS only for a holding pulse width and then, the pulse voltage is made to 0 V. The electric charges charged in the inter-electrode capacity are stored in a condenser 8 through the coil 9. When FET 5 is turned on, the inductance value is decreased and the voltage approaches to 0 V steeply, and all the charges are stored in the condenser 8.  Thus, electric power loss by charging and discharging the inter-electrode capacity CP is decreased.

Title: Storage controller and printer having the same
Inventor: SHIMA TOSHIHIRO
IPC: B41J29/38
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To improve a data transfer speed of an auxiliary storage device. SOLUTION: In writing data in an auxiliary storage device, this storage controller reads out the data from a first buffer memory (S101) after it opens a file (S100), and writes data of a specified block size in a metafile 110 on the auxiliary storage device (S102 to S105). The metafile is edited sequentially. Even when writing of the data is completed, the file is not closed. When the data are read from the auxiliary storage device, the file is opened (S111) and the data are read from the metafile (S112 to S114). Even after reading of the data is completed, the file is not closed. Thus, it is possible to sequentially perform write and read and to improve a transfer speed by using the auxiliary storage device as a so-called ring buffer.

Abstract: PURPOSE:To set the ranking of voltage, by comparing each output signal voltage given from a sensor array with the reference voltage which varies in a simple way and then counting the changing frequencies of the level compared with the reference voltage. CONSTITUTION:The output voltages V1...Vn of photosensors 1...n are connected sequentially to inrersion detecting circuits 41...4n via transfer gates 11...1n and a shift register 20. At the same time, a comparator 30 compares the output voltage Vi (i=1...n) with the reference voltage and delivers ''1'' and ''0'' to the circuit 41 in the case of Vi>V and Vi<V respectively. The voltage V is simply increases or decreased, and the circuit 41 delivers a pulse only when the output of the comparator 30 is inverted. This pulse is counted up or down from an FF100 by an n-bit counter 120, and the final count value is fed to shift registers 141...14m. In such a way, the ranking can be set to the output voltage of each sensor of a sensor array by the count value.

IPC: G07B1/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To solve the danger that a password number is discriminated by adjacent persons by sequentially changing the key array of a ten key shown on a liquid crystal display part each time a commutation ticket is issued. SOLUTION: When a displaying part shows a throwing image of a password number, a main CPU gets a value that is generated from a random value generating part (ST1). Next, the main CPU selects and reads one of screen display formats from a password image display file, selects and reads one array of ten keys from a password key file and edits them to a password number input image (ST2). Thus, the main CPU shows the edited password number input image by a displaying part (ST3). And when a password number of four digits is inputted (ST4), the processing is finished. Then, it is impossible for adjacent persons to estimate which key is inputted from finger movements when the password number is inputted.
