Title: Track control method for optical disk device
Inventor: SHIMABARA NORIO
IPC: G11B7/085
Filed: 1990-02-05
Abstract: PURPOSE:To exactly control tracks by moving an optical head to the outer side of a standard format region (SFP) part and moving the optical head to the target track on the basis of the position where the output of this optical head continues for a specified period of time. CONSTITUTION:The optical head is once positioned to the outer side of the SFP part and a processor 11 sends a command to a control section 10 to move the optical head by one track each to the inner side. Signals exist in the entire circumference of the SFP part. The processor 11 is interrupted and the optical head is put into a static state when a signal detecting circuit 12 detects the signal. The optical head is, therefore, positioned exactly to the outermost circumference of the SFP part. Since the number of the tracks between the SFP part and the track 0 is known, the optical head is moved by as much as the value obtd. by adding the number of these tracks to the target track. The optical head is exactly positioned to the target track in this way.

Title: Sheet paper or the like identifying device and sheet paper or the like identifying method
Inventor: HATANAKA HARUO
IPC: G07D7/20
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To quickly cope with an illegal ticket by comparing and discriminating the pattern data of a legal ticket and the pattern data of illegal tickets including the latest ones with inputted sheet paper or the like. SOLUTION: The latest illegal ticket data which is inputted and is sent from other computers or a bill identifying machine 2 is registered on a host computer 1. The latest illegal ticket data of the computer 1 is sent on an intranet 3 outside bill identification operation time. The machine 2 receives this data and writes it on internal memory. When a bill is inputted, it is undergone bill identification processing, and when it is decided that it is illegal, it is undergone return processing and returned from a bill inserting slot. When it is decided that it is close to a legal ticket, it is performed pattern matching with registered latest illegal ticket data to decide the truth of it. When the pattern coincides with it, it is decided as an illegal ticket and it is returned. When it does not coincide, it is finally decided as a legal ticket and performed acceptance processing.

Abstract: PURPOSE:To make a very low speed of a motor possible, by creating a voltage which is higher than a set speed control voltage by a bass to emitter voltage and feeding with it a transistor base whose motor driven coil is connected to an emitter. CONSTITUTION:A position detecting signal from an A phase Hall element 2 is converted into a switch signal by a differential amplifier 3, and supplied to a transistor  TrT32 through a series of transistor, and the TrT32 outputs a 180 deg. on-off signal of  the positive phase or the negative phase with a control by a positive-negative control circuit 4. TrT17, T18 are controlled by a signal a from the TrT32 and a reverser (a). A current IB supplied from a TrT19 flows to Darlington circuits T13, T14 and T15, T16 with the ''on'' state of TrT17, T18, so that voltage at the connecting point of transistors T1, T2 is controlled to be identical with a speed control voltage VS. In other words, a minimum neccessary current IB to make approximately nil the collector to emitter saturation voltage with the TrT1 in a saturated state can thus be formed.

The pump current is flowed through the oxygen pump element 7 in two directions so that the electromotive force has a specific voltage, namely, that the air fuel ratio in the diffusion chamber 15 is constant, and the air fuel ratio is detected from the current value. Thus, the oxygen pump current is con trolled in both directions to detect the air fuel ratio, which is therefore detected from rich to lean continuously.
