Title: Disk store case
Inventor: OOHASHI SHINICHI
IPC: B65D85/57
Filed: 1983-09-05
Abstract: PURPOSE:To avoid the soil and wear of the information recording surface of a hard disk by forming a spindle inserting hole to a disk store case and at the same time a supporting part for an area of the disk excepting the information recording surface. CONSTITUTION:The inside space between a case main body 4 and a cover 6 is narrowed at the outer circumference part of a disk 2, and this outer circumferential part is held lightly at the inner side of the case. The space between the disk 2 and the inner side of the case increases at the inner circumferential part of the disk 2. Therefore the information recording surface of the disk 2 has no contact with the main body 4 nor the cover 6. A spindle 5 which is positioned vertically on the basis of a reference surface 7 is loaded to a disk 2 through a spindle inserting hole 8. Under such conditions, the spindle 5 is rotated to give rotation to the disk 2 without having a contact between the informaton recording surface of the disk 2 and both main body 4 and cover 6 respectively.

Abstract: PROBLEM TO BE SOLVED: To align the incoming/outgoing direction of light accurately with the in-plane direction, the thickness direction and the warping direction of a substrate when an optical element is fixed onto the substrate. SOLUTION: Metal layers 13a, 13b, 23a, 23b are formed on the bottom face of an optical element 1 and a substrate 2 and then the optical element 1 is mounted on the substrate 2. Subsequently, the metal layers 13a, 13b, 23a, 23b are fused thermally and cooled thus bonding the optical element 1 onto the substrate 2. When the metal layers 13a, 13b, 23a, 23b are divided in the direction traversing the optical axis 12 of the optical element 1, the metal layers 13a, 13b, 23a, 23b are prevented from inclining at the time fusing. This arrangement prevents the optical element 1 from being warped.

Inventor: IIDA YUKIO
IPC: H01M50/541
Filed: 1988-06-29
Abstract: PURPOSE:To make it possible to weld the lugs of electrode plates in a good condition by feeding a molten lead A more than the amount necessary to form straps in the pattern holes for strap formation. CONSTITUTION:To pattern holes for strap formation, a molten lead A1 more than the amount necessary to form straps is fed, the calorie of the molten lead A1 is utilized to weld the lugs 6 of electrode plates while heating the lugs 6, and excessive molten lead A1 is collected from the strap formation pattern holes 1. After the straps are formed by solidifying the molten lead which has welded the electrode plate lugs 6 in the strap formation pattern holes 1, the straps are removed from the strap formation pattern holes 1. As a result, the molten lead A comes to have a sufficient calorie to heat the electrode plate lugs 6 up to a specific temperature. Consequently, the welding of the electrode plate lugs 6 can be carried out in a good condition by the heating with the molten lead A which has a large thermal capacity.

Filed: 1978-12-26
Abstract: PURPOSE: To enhance production efficiency of coils by using a winding frame that is assembled so that materials having different heat conductivity are contacted depending on the wire-distribution density of coils.  
     CONSTITUTION: The winding frame for coils is prepared in conformity with the design of a coil shape in such a way that a material having a large heat conductivity is contacted with the portion where the coil shape is thick and the wire-distribution density is high, and a material having a small heat conductivity is contacted with the portion where the coil shape is thin and the wire-distribution density is low. As for a method of assembling to the winding frame, it is recomended that ceramics, heat-resistant synthetic resin, and the like are embeded, applied or coated on the portion where the wire distribution density of the coil is low, with an iron-chromium plating material as a base material, from the view point of durability.

Filed: 1995-06-05
Abstract: PURPOSE: To prevent any partial wear of an abrasive wheel from occurring to make improvements in device operation rate by dispensing with any contact adjustment to a work at the time of this abrasive wheel being worn out by pressing a wheel surface of this abrasive wheel elastically to a ridge angular part at a fixed force. CONSTITUTION: An abrasive wheel 12 and a liquid crystal panel 25 are positioned, then this abrasive wheel 12 is driven at the specified revolution by a motor 13, and the wheel surface 17A is brought into slide-contact with a ridge angular part of the liquid crystal panel 25. In addition, this panel 25 is shifted along an arrow X direction. In consequence, the specified chamfering is applied to the ridge angular part of the panel 25. In this chamfering, the abrasive wheel 12 is always energized at the specified power by a spring 22 in the axial direction of a turning shaft 15. Accordingly, supposing that there is a manufacturing error in an external form of the panel 25, a fixed quantity of chamfering can be done at all times.  Thus chamfering is applied to this wheel surface 17A, and this surface 17A is brought into slide-contact with a top face of the liquid crystal panel 25 at an angle of 45 deg., whereby the chamfering to a terminal part (level difference part) of this panel 25 also can be done easily.

Title: Steering device for magnetic induction type unmanned carrier
Inventor: MUKOGASA YUKIO
IPC: G05D1/02
Filed: 1988-06-30
Abstract: PURPOSE:To enable a carrier to smoothly pass a branching point by adding a signal delay element to a shift signal generating circuit to give a delay characteristic to the shift signal which is obtained by detecting a shift mark at the branch point of a running route. CONSTITUTION:When the carrier detects the shift mark on the running route to turn on a shift switch 5R, the operation signal of the shift switch 5R has the polarity inverted by an inverting amplifier 10 and is inputted to an amplifier 8 through resistors R3 and R7 as a negative shift signal (-) controlled by a variable resistor VR2. In this case, the shift signal has a delay characteristic by a capable C2 as the delay element and slowly rises. Simultaneously, the operation signal of the shift switch 5R is inputted to an OR circuit 16 to turn on a contactless switch 15. Consequently, the output of the magnetic sensor is approximately cancelled by the shift signal, and the steering signal is about zero in the pass area of the branch point. Thus, the carrier is run along a guide magnetic tape 2a of the branch at a stable attitude without meandering.
