Patent JP-S6265247-A (JP)
Title: Optical pickup device
Inventor: TSUJI SHIGEKI
IPC: G11B7/135
Filed: 1985-09-13
Abstract: PURPOSE:To prevent a false signal and a false information siganl from being generated by forming a light reflecting surfaces which is a half-reflecting surface and reflects light in a direction different from that of the fitting surface of a beam splitter on the fitting surface and reduce extremely the quantity of part of a beam which is reflected by the fitting surface and strikes on a photodetecting element. CONSTITUTION:Part of a laser beam which is incident on the beam splitter 4 from a laser diode 1 and reflected by the half-reflecting surface 4a toward the fitting surface 21a is reflected by the light reflecting surfaces 22a of a concave part 22 to enter the beam splitter 4 again from a surface A and exit from a surface C as stray light. At this time, the beam is reflected by the tapered reflecting surface 22a in a different direction from the incidence direction and the beam is refracted when striking on the surface A of the splitter 4 and exiting from the surface C, so the light exits from the splitter as stray light in a direction different from the optical path of a siganl detection part 10. Consequently, the quantity of the stray light incident on the photodetecting element 9 of a detection part 10 is made small enough not to exert influence upon the servo system.

IPC: G06T11/20
Filed: 1983-10-31
Abstract: PURPOSE:To speed up vector writing operation by calculating previously the number of dots in a row (column) direction, and repeating bit access function in a column (row) direction and varying the number of bits by a specific value corresponding to each access operation in the row (column) direction at a time or continuously. CONSTITUTION:When a vector between a point r, e.g. (3, 3) and a point S, e.g. (6, 8) is re-stored in a memory, the X-directional difference DX between the coordinates and Y-directional difference DX are 3 and 5, and the number of times of loop operation in a flow chart is five. The number of a set of dots arrayed in the Y-direction is determined by DY-2DXi+2SYj shown by an equation A. A downward coordinate (i) and the value of A are varied and i+1 and A-2DX are substituted in (i) and A to move a pen by one dot slantingly to right unless the value is smaller or zero. A leftward coordinate j+1 is substituted in (j) and A+2DY is substituted to move the pen by a unit number in the Y-direction when the loop frequency is zero or plus.

Filed: 1990-07-31
Abstract: PURPOSE:To work a piping having a large-diameter part, small-diameter part and connecting hole with fewer man-hours by subjecting the piping connecting hole to burring with a projection for burring simultaneously with bulging of the large-diameter part by pressurization of a bar-shaped elastic member. CONSTITUTION:A pipe stock 4 is first mounted to a metallic mold 1 and the front end thereof is fitted to a projecting part 14 of a fixing base 12.

Title: Container lid and its preparation
Inventor: TERAJIMA KOKI
IPC: B65D17/40
Filed: 1987-08-18
Abstract: PURPOSE:To facilitate the starting of release, to open a can lid in an extremely easy manner and to secure sealability, by providing a part requiring no release to a release start part. CONSTITUTION:Since a non-adhesive part 6a has a shape depressed in an adhesive region 8 from the outside contour thereof, the possibility of opening at an unnecessary time is extremely reduced. Since the inner edge contour of the second intermediate material 6 is present inside the inside contour T of the adhesive region 8 by a distance (d), the second intermediate material 6 rises at the part of a range wherein the distance from the inner edge contour is (d) with the rising of a base material 4 due to the action of release force F and, as a result, the force F always acts on the boundary of the inner laminate material 7 and the flange 3 of a container main body 2, that is, the inside edge T of the adhesive edge 8 while the adhesive region 8 is not released because it has sufficient bonding strength due to heat-sealing. A container lid 1 can hold sufficient sealability to both of external force and internal pressure.

Title: Control of cell activity
Inventor: SATO SATOSHI
IPC: C12N5/02
Filed: 1994-08-30
Abstract: PURPOSE: To control cell activity for use in medical techniques and productions of useful materials by adding LiCl to a culture medium for eucaryotic cells, lowering the cell activity for incorporating extracellular materials into the cell and suppressing endocytosis without inhibiting cell proliferation. CONSTITUTION: This method for controlling cell activity is to cultivate eucaryotic cells such as human culture cells HT1080, etc., in a culture medium for eucaryotic cells mixed with 10-100mM lithium chloride and lower or stop the cell activity for incorporating extracellular materials (endocytosis) without inhibiting cell existence and cell proliferation. The lowering or stopping of the endocytosis is confirmed by adding horseradish peroxidase(HRP) into the culture medium after a certain time from the addition of lithium chloride and measuring the enzyme activity of the incorporated HRP into the cells after a certain time after the addition of the HRP. By this method, it is easy to selectively lower or stop the endocytosis. This method controls the cell activity and leads to open new applications in medical techniques for individual existence and the use of cells contributing to productions of useful materials, etc.
