Abstract: PURPOSE: To simplify adjustments of the position of a photo detector and magnification of a lens system, by using a line-scanning photo detecting element in addition to an adjusting pattern adaptable to this photo detector.  
     CONSTITUTION: Sheets of paper P with entry item 1 for a postal code, etc., are conveyed, on by one, by the conveyor mechanism and when a sheet of paper P reaches a fixed position, it is lightened by lamp 2 and its reflected light is led to solid-state scanner 4 via lens system 3 with fixed magnification, thereby forming the image. This scanner 4 is controlled by control circuit 6 to amplify sequentially video signals at fixed intervals and to send out them to the processing circuit at the next stage. For the constitution of this constitution, test form 7 with drawn adjusting pattern 8 of black and white squares continuing longitudinally is used and each image of this adjusting pattern 8 is sized large enough to coincide with one bit of scanner 4, so that the position of scanner 4 and magnification of lens system 3 will be adjusted correctly by using this adjusting pattern 8.

Title: Stereo amplifier circuit device
Inventor: OOSHIMA HIDEAKI
IPC: H03F3/68
Filed: 1984-04-20
Abstract: PURPOSE:To improve the transient characteristic by activating the 1st amplifier circuit and the 2nd amplifier circuit having a commond DC power supply circuit in opposite phase to each other so as to suppress remarkably an output current of both channels flowing at the same time thereby decreasing a peak value of the current applied to the amplifier circuits and decreasing a voltage drop due to a line impedance and an internal impedance of the power supply. CONSTITUTION:One input amplifier 6a of the 1st amplifier circuit 1a is constituted as an inverting amplifier with an operational amplifier A1 and resistors R7, R8 and other input amplifier 12 is constituted as a non-inverting amplifier. As a result, transistors (TR)8, 9 of the output stage of the 1st amplifier circuit 1a are driven in opposite phase to TRs 14, 15 of the output stage of the 2nd amplifier circuit 2. Then one speaker 3 is connected to an output terminal 10 in opposite polarity. Since the 1st and 2nd amplifier circuits 1, 2 are driven oppositely, the left channel current and the right channel current flow alternately. Thus, a current I of a single channel flows to each section.

Abstract: PURPOSE:To prevent the slacking of a tape unnecessarily when a tension controller is released and to smoothly change-over the tape to a reverse reproducing mode by providing separately a tension detecting means and a braking force variable means to make variable the pressuring force of a rotary member. CONSTITUTION:When a magnetic recording and reproducing device is changed over to a recording reproducing mode, a tape 1 is driven in the A direction of an arrow, then, the tape tension occurring at the 1 is detected by a tension post 2, the pressuring force to the reel base braking part 4 of a braking belt 5 is made variable by the balance of the force turning a tension arm 10 in the clockwise direction and a tension spring 9. The tape tension is made constant. Next, when the device is changed over to a reverse reproducing mode and a tension arm 11 is forcibly released from the external part, the pressuring force to the reel base braking part 4 of the braking belt 5 is made variable, and a large driving source is not necessary to rotate a supplying reel base. In such a case, the tension post 2 is abutted to the tape 1 by a subtension spring 12.

Title: Optical system driver
Inventor: TATSUNO TORU
IPC: G11B7/085
Filed: 1986-04-09
Abstract: PURPOSE:To correct the fall of the optical system of an optical system caused on a plane which is formed by the rotational center of an arm member and the optical axis of the optical system, by rotating the arm member at a proper angle to give displacement to the optical system. CONSTITUTION:It is assumed that an optical axis 115 of an objective lens 101 set in a lens holder 102 is fallen at an angle theta within a rotary plane of the lens 101 while no current flows to a focusing coil 109. An arm 103 is turned at an angle theta by the electromagnetic focus produced by supplying a fixed current for correction to the coil 109. Thus the lens 101 is displaced for correction of fall of the axis 115. Based on this state, the lens 101 is moved toward the axis 115 for focusing. In such a way, the fall of the axis 115 can be corrected within the rotary plane of the lens 101 by supplying a fixed current to the coil 109 in response to the fall angle.

IPC: E04H9/02
Filed: 1987-03-31
Abstract: PURPOSE:To prevent the manifestation of elasticity even when horizontal displacement increases by a method in which a structure is supported on a foundation through an earthquake isolator, and both ends of a lead bar of a set length are fixed to the structure and the foundation respectively. CONSTITUTION:A structure 1 is supported on the foundation 2 through an earthquake isolator 3 formed by alternately laminating thin elastic plates and rigid plates, and both ends of a lead bar 14 having a specific shape are fixed to the structure 1 and the foundation 2 to make up an earthquake isolating device 10.

When the structure 1 and the foundation 2 are in relative movement, the axial expansion or contraction of the bar 14 does not occur only when the straight-line distance of both ends of the bar 14 is within the whole length, and therefore, energy is absorbed dependently only upon bending and shearing deformation.

Abstract: PURPOSE:To prevent the malfunctions of a customer system owing to the wrong correction information by deciding the propriety for application of the correction information and copying the contents of a correction information reception file to a correction information operation file only when the correction information is applicable. CONSTITUTION:The correction information on a control program of a customer system 3 which is transferred from a maintenance center system 1 is stored in a correction information reception file 33A of the system 3 via a public circuit 15. A correction information application confirming means 322 decides whether the correction information stored in the file 33A is applicable to the control program of the system 3 or not.
