IPC: G06K7/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To easily match scanning light with the barcode of a barcode sheet and also to unnecessitate a precise controller. SOLUTION: In laser light from a laser source 12, optical paths L1, Lb and Lc are directed to a first reading range R1 with multi-surface reflection mirrors 22 at the time of a reflection mirror where the plane tilt angle of a polygon mirror 14 is not so large but the optical path Ld of laser light L from the laser source 12, which is reflected by the reflection mirror where the plane tilt angle is specially large is directed to the second reading range R2 separated from a first reading area R1 direction. Since the line of sight of the second reading range R2 used in a barcode sheet reading mode is arranged so as to view the range R2 without the disturbance of a case 6, the second reading range R2 is easily discriminated by an operator, the range R2 is efficiently positioned and a reading mistake is more reduced.

Title: Storage device subsystem
Inventor: YAMAMOTO YASUTOMO
IPC: G06F13/12
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To improve throughput of an entire storage device subsystem due to the reduction of transfer bus reservation opportunity in read/write command processing that is queued to a disk drive, disk drive occupancy time reduction and overhead reduction on a host side. SOLUTION: Both a request command and write data are transferred in one transfer bus reservation when a write request is made queuing to a disk drive 105 and held by a buffer 109 in the drive 105. The request command that is made queuing is scheduled with head positioning time considered, and the write request is processed and executed without being reconnected to a host. Also, when a command queuing is performed in a disk drive that has plural interfaces, information that specifies a host is internally stored so that a completion report of request processing can be returned to the host that sends a request command and it is used at the time of the completion report.

Title: Control method of air-fuel ratio
Inventor: MIYANO TAKASHI
IPC: F02D41/14
Filed: 1983-11-15
Abstract: PURPOSE:To control air-fuel ratio to a constant value without reference to aged deterioration, by monitoring the aged deterioration of a throttle actuator through the output of an A/F sensor so as to correct the air-fuel ratio, in the case of an EAC system. CONSTITUTION:Air-fuel ratio is detected through an A/F sensor 2 provided in an exhaust pipe and monitored by an MPU3. The MPU3 stores a basic characteristic when an engine is in normal operation, and the output from a throttle actuator 4 corrects the basic characteristic by calculating a correction amount from a value stored in said MPU3 and a value detected from the A/F sensor 2. In this way, the air-fuel ratio can be controlled to a constant value without reference to aged deterioration.

Title: Information medium
Inventor: YUDA NAOKI
IPC: B42D15/10
Filed: 1991-08-26
Abstract: PURPOSE:To obtain an information medium provided with a metal ring, which protects the information medium from an impact from the external and never reduces an area of a transmission range, in an information medium for transmitting data and electric power to/from a reading and writing device of non-contact system using electromagnetic coupling. CONSTITUTION:A metal ring 9 with a cut part 9x mounted on the periphery of a transport body 2 protects an information medium 1 from an impact from the external. Furthermore, by decorating the metal ring 9 by plating or the like, the information medium 1 can have a good texture and a rich body. The forming of the cut part 9x in the metal ring 9 results in the metal ring 9 of a shape never forming a closed loop. Therefore, when a signal of a magnetic field is applied from the external, there is no possibility that a loop current may pass through the metal ring 9 to interrupt a magnetic flux crossing to a first coil 3. Thus, a wide transmission range can be ensured.
