Title: Device for positioning printed board
Inventor: FUJISHIRO KEISUKE
IPC: H05K13/04
Filed: 1989-01-30
Abstract: PURPOSE:To adjust intervals between guide members as well as positioning pins by performing adjustment corresponding to boards having different sizes through utilization of drive means of an XY-table. CONSTITUTION:When adjustment is performed by reducing intervals between guide members 7 and 8, a stopper 22 to the guide member 8 is moved to hold a position shown with the solid line in a figure by lowering an upper plate 5 and moving an XY-table as the occasion demands, thereby lowering the stopper 22. Then clamping is released by operating an air cylinder 16. In such a state, a drive motor 6 in a Y-direction moves a Y-table 3, that is, the upper plate 5 in the direction of a solid line with arrow in the figure until the intervals between the guide members 7 and 8 reaches a prescribed distance. Adjustment of the intervals both between the guide members as well as positioning pins is thus performed exceedingly easily.

Title: Independent type rear suspension
Inventor: MITOBE KEIICHI
IPC: B60G7/02
Filed: 1985-02-06
Abstract: PURPOSE:To enhance the flexibility and rigidity of a suspension, by providing such an arrangement that the inner end of second arm section of a lower control arm is journalled to a subframe which extends widthwise of a vehicle and which is attached to a vehicle body through the intermediary of a resilient member at the position that is different from the journalled position of the second arm section in the vertical direction. CONSTITUTION:When rearward force acts on a subframe 10 from a lower control arm 4 in the longitudinal direction during braking, the subframe 10 swings rearward while it deforms a resilient member 11 since the fulcrum of the subframe 10 on a vehicle body 10 is higher than the fulcrum of second arm 6 of the lower control arm 4 on the subframe 10, and therefore, the lower control arm 4 may be displaced rearward to ensure compliance. With this arrangement, it is possible to enhance the flexibility and rigidity of the suspension.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical disk in which information can be recorded and reproduced with reference to two or more recording layers by only one optical head device by installing a hub mechanism by which a first substrate and a second substrate bonded via an adhesive layer are supported so as to be rotatable by a shaft-shaped rotation means. SOLUTION: An optical disk device is formed in such a way that incident light 22 can be condensed independently both with reference to a track 34 on a substrate 10a and with reference to a track 34 on a substrate 10b. That is to say, the incident light 22 which is passed through objective lenses 21 is condensed on either the track 34 on the substrate 10a or the track 34 on the substrate 10b according to recording signals 28, 19 to be utilized. In addition, when information is recorded on the recording layer 29 or information is reproduced from the recording layer 29, the incident light 22 becomes transmitted light which is transmitted through the recording layer 28.  Consequently, when the information is reproduced from the recording layer 29, the incident light 22 takes a route in such a way that it is transmitted through the recording layer 29 so as to reach the recording layer 29 and that it is by the recording layer 29 so as to be transmitted through the recording layer 28.

Abstract: PROBLEM TO BE SOLVED: To prevent lowering of fixing force of a fitting fixing part due to change eclipse, the change of temperature or the like by providing a shape holding means for constantly holding the inside diameter of the fitting fixing part of a cylindrical member on the inner circumference of the cylinder member positioned in the inside. SOLUTION: When the diameter of a cylindrical member 5 for minute pointer output is reduced and deformed, fixing force of the fitting fixing part of the inner circumference of a cylindrical member 4 for a minute pointer and the outer circumference of the cylindrical member 5 is lowered, and proper rotation of the minute pointer can be performed. However, even if the diameter of the member 5 is reduced by fitting and inserting a column-like pin 21 on the inner circumference of the member 5, which is deformed, the column-like pin 21 constrains the inner circumferential face of the member 5, and a constant diameter is held. Accordingly, the diameter of the member 5 is not reduced and deformed. As the result, lowering of the fixing force of the fitting fixing part of the inner circumference of the member 4 and the outer circumference of the member 5 can be prevented.
