Title: Constant velocity universal ball joint
IPC: F16D3/223
Filed: 1993-01-12
Abstract: PURPOSE: To improve abrasion resistance of a universal ball joint and make polishing and classification of parts unnecessary by subjecting the surface regions of track faces of outer and inner joint parts receiving loads by balls and surface regions of guiding faces for a retainer adjoining through ball tracks, and providing unhardened zones between each two ball tracks between the guiding faces. CONSTITUTION: Ball tracks 9 of the outer joint part 1 and the inner surface 13 between ball tracks are subjected to hardening operation along the marginal regions of the ball tracks as shown by the dotted lines. The same regions constitute the guiding faces 16 running in the axial direction along the marginal regions 15. Hardening embraces the running track faces into the surface zones of the ball tracks 9. Ball tracks 10 of the inner joint part 4 and the regions of the outer surface 14 between each tracks shown by the dotted lines are subjected to hardening operation. The regions constitute the guiding faces 18 running in the axial direction along the marginal regions 17 of the tracks 10. Hardening embraces the running track faces into the surface zones of the ball tracks 10.  Thus, hardening of the retainer 6 and the guiding track faces between the inner and outer joint parts 4, 1 with respect to improving abrasion resistance can eliminate polishing and classification which could give an adverse effect after hardening operation.

Title: Virtual memory control system
Inventor: SHIMIZU OSAMU
IPC: G06F12/12
Filed: 1978-02-21
Abstract: PURPOSE: To omit the operation, by which the information collection to which the declaration of access completion is given is stored in a main memory again, by installing the information management unit which manages concentratedly the information collection accessed by a CPU.  
     CONSTITUTION: When CPU 1 starts access, information management processor (DSCP) 21 in information management unit 26 searches information management register (DSR) 17 and loads assigned information collection (DS) 4 from external  memory 9 to main memory 2 and auxiliary 3 if this collection has never been loaded, thereby completing access. Simultaneously, DSCP 21 makes main memory block  24, which is occupied by DS 4, into a semi- available state. After that, when CPU 1  has access to the same DS 4, DSCP 21 finds that DS 4 has ever been loaded and is  left in the semi-available state by DSR 17, etc., and completes the load processing  without storing DS 4 again from external memory 9 and auxiliary memory 3 and informs CPU 1 of the load completion.

Title: Reversible recording medium and image erasing method
Inventor: KOSHIMIZU MINORU
IPC: B41M5/26
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a reversible record indicating medium applicable to a transparent type onto which a user can write a character at an arbitrary writing speed or writing pressure, i.e., can indicate an image, and a convenient image erasing method applicable thereto. SOLUTION: The reversible recording medium comprises a fluid substance 14 wetted in the air gap of a porous layer 12 laminated, on the back thereof, with a transparent support 14. When printing is performed according to image information using a printer having a pressure serial head 20, the fluid substance 14 held in the air gap of the porous layer 12 migrates from the part applied with the printing pressure to the periphery. Consequently, an unfilled air gap 12A appears in the porous layer 12 to bring about a light scattering state and an image is displayed.

Title: D-type flip flop
Inventor: SUZUKI RYOICHI
IPC: H03K3/3562
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To eliminate insufficient charging of a D-type flip flop, even when the speed of the frequency is significantly increased by securing a longer effective charging period, including the charging period by charging the flip flop by driving an independent charging system in a stage before shifting to the charging period, immediately after different states of potentials (low potential- and high potential-side power supply potentials) are decided with respect to the two input terminals of an RS latch in an evaluating period. SOLUTION: A set input terminal S of an RS latch 2 is charged through a Pch transistor TP1 and also via a transistor TP3 and a Pch transistor TP50 by setting the transistors TP50 and TP51 in conducting states and, in addition, an NCh transistor TN300 in nonconducting state, by outputting a VSS potential from a two-input EXNOR circuit XNOR, at the same time as from the time when the set input terminal S of the latch 2 becomes a VDD potential and the reset input terminal R of the latch 2 becomes a VDD potential in an evaluating period, not after starting a charging period, but starting already in the evaluating period.  Even when the evaluating period starts from a state where the set input terminal S is in a VDD-potential state and the reset input terminal R of the latch 2 is in a VSS-potential state, the charging is also started similarly not after the charging period starts, but in the evaluating period.

Filed: 1993-02-08
Abstract: PURPOSE:To uniformly ground a transparent substrate, to obviate the intrusion of bubbles in a molding stage, to uniformly spread a resin and to stabilize performance by supplying the resin with nozzles at >=2 points. CONSTITUTION:The 2P resin is applied by one piece of the nozzle onto a metallic mold 3a and the transparent substrate is placed on the 2P resin. The 2P resin is forcibly spread by applying a pressure thereto via the metallic mold 3a and the transparent substrate. The 2P resin, however, is not spread uniformly on the concentrical circle and cannot be transferred similarly to the metallic mold 3a. One piece of the nozzle is thereupon added to the part where the 2P resin is not spread and the 2P resin is applied by two pieces of the nozzles 1a, 1b. The transparent substrate is thereafter placed on the resin and the pressure is applied thereto via the metallic mold 3a and the transparent substrate to forcibly spread the 2P resin. The resin is spreaded and the transference is executed in the same manner as for the metallic mold 3a in such a manner. As a result, the transparent substrate is uniformly grounded and the 2P substrate for the optical disk having the stable performance is obtd.
