Title: Brushless motor driver
Inventor: NAKAMURA MASATO
IPC: H02P6/06
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To avoid the deterioration of the performance of a motor by a method wherein an offset signal which cancels a phase shift is generated in accordance with a rotor position detection signal and supplied to a position signal generating means. SOLUTION: Differential amplifiers 81a and 81b amplify position detection signals (e1 and e2 ) and (e3 and e4 ) which correspond to the rotation positions of a rotor 2 and whose phases are opposite to each other and, further, correct position detection signals which are distorted by the influences of magnetic fields generated by an armature coil 6 in accordance with offset signals (nf and ng) supplied from a timing correcting means 82. That is, rotor position signals (E12 and E21 ) and (E34 and E43 ) which have phases same as the position detection signals (e1 and e2 ) and (e3 and e4 ) and have a phase difference in an electrical angle of (π/2) corresponding to correct detected positions between each other are generated.  The offset values of input offsets are so predetermined as to cancel error voltages which are generated in Hall devices HG1 and HG2 by disturbance magnetic fields (f and g).

Title: Parking lot management device
Inventor: KAWAHARA TOSHIYUKI
IPC: E04H6/00
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To automatically retrieve the parking spaces in the parking and leaving modes of vehicles and to simplify the management of a parking lot. SOLUTION: The number of a vehicle 3 is read by a number reader 5 and at the same time the operation of a remote operation device 6 is detected by a receiver 7. Thus a controller 20 retrieves a parking space A2, for example, for the vehicle 3 as long as it is registered. Then the controller 20 turns on the guide lamps 10 and L2 for the space A2 and then opens a gate 8. If plural parking spaces are registered in a parking office, etc., an idle space is retrieved and displayed. Furthermore, a ticket issuing machine 11 issues a parking lot to a visitor vehicle. When a parking lot is filled with vehicles, a full-parking state display 12 is turned on. Then the lamps 10 and L2 are turned on again when a vehicle leaves the parking lot. When the visitor vehicle leaves the parking lot, the parking fare adjustment is carried out by a fare adjustment machine 13.

Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To simplify an operation in a simulation mode by storing information regarding an order of a plurality of types of regulating operations for regulating respective type regulating items in the mode and conducting a plurality of types of the operations in the order along the information. SOLUTION: Information regarding an order of a plurality of types of regulating operations for regulating respective regulating items are previously stored in a memory of a copier.

Thus, the operation in the simulation mode can be simplified.

Title: Power supply circuit for tape recorder with radio set
Inventor: KOBAYASHI TOSHIHIKO
IPC: G11B31/00
Filed: 1986-12-19
Abstract: PURPOSE:To obtain a stable DC power supply by providing a sound recording/ reproducing switch at the output side of a bias oscillator. CONSTITUTION:A sound record bias oscillation circuit is started regardless of the recording/reproducing state since the bias oscillation force is needed even when the radio is received. Therefore the recording/reproducing switches S1-1 and S1-2 are set at the output side of a bias oscillator for supply of the bias or the erasion current in a normal recording state. At the same time, an impedance element equivalent to an erasion head is earthed at the reproduction side of a recording/reproducing switch S1-3 so that the oscillation force has no fluctuation against the changeover of those recording/reproducing switches. As a result, the DC output obtained at an output terminal 24 is stable and equal to the Zener voltage level of a Zener diode D2. This stable voltage is applied to the DC input terminal of an low pass filler (LPF) to secure an actuation equivalent to a DC/DC converter.
