Title: Method for molding corner part of glass run
Inventor: YAMAGUCHI TOSHIAKI
IPC: B29L31/10
Filed: 1986-08-20
Abstract: PURPOSE:To make it possible to mold a corner part, which follows up to the rectangular shape of a sash, by a method wherein acute projections, which form folding grooves by being penetrated in the inner periphery of the corner part of a glass run, are provided on the apex of a bottom force, which has a chevron-shaped cross section. CONSTITUTION:A groove 7 is formed over both slanting surfaces 17 and 18 on the top face of a bottom force 16. In addition, acute projections 22 and 23 are formed along the apex 19 of curved recessed 20 and 21, provided at both sides of the groove 7. Firstly, a notched part 6 is shaped by cutting off a slice 5 ranging over both the side walls 2 and 2 and the base wall 3 of a glass run 1 so as to engage a part left uncut 12 with the projected edges 10 and 10 of a core 11. The resultant core 11 is fitted to the groove 7 of the bottom force 16 and covered by a top force and finally thermoplastic resin is poured in the notched part 6 in order to be cooled an hardened. The projections 22 and 23 are penetrated by mold clamping pressure in the inner periphery 13a of a corner part 13 so as to form folding grooves 24 on the inner periphery. Accordingly, no restoration of the inner periphery 13a by elastic force develops and the inner periphery 13a, without restoring the original shape by resilience, keeps the shape, which is formed by being bent through the folding grooves 24 at almost right angles. Consequently, the obtained corner part can be accurately followed up to a sash 15, which is bent at almost right angles, with no gap left between the corner part and the sash.

Title: Inorganic nonaqueous electrolytic battery
Inventor: SHIMOMITSU TOMOYUKI
IPC: H01M6/14
Filed: 1991-07-08
Abstract: PURPOSE:To reduce voltage drop at an initial stage of discharging by using AlCl3 or LiCl and AlCl3 of higher concentration than LiCl are used for an electrolyte of an electrolytic solution, and by including sulfuryl chloride in the electrolytic solution. CONSTITUTION:AlCl3 or LiCl and AlCl3 of higher concentration than LiCl are used for an electrolyte of an electrolytic solution, and sulfuryl chloride is included in the electrolytic solution. Voltage drop at an initial stage of discharging is caused by the fact that a LiCl film on the Li surface of a negative electrode becomes resistant at the starting time of discharging, and that, as a result, discharging of no more than normal voltage continues until the LiCl film is dissipated. When the LiCl concentration in the electrolytic solution is lower than AlCl3 concentration, since the LiCl film on the Li surface of the negative electrode is dissolved into the electrolytic solution so as for LiCl and AlCl3 to form LiAlCl4 in the electrolytic solution, voltage drop at an initial stage of discharging is reduced.

Title: Tape running stabilizing mechanism
Inventor: TAKADA MASAHIKO
IPC: G11B15/29
Filed: 1983-10-17
Abstract: PURPOSE:To stabilize running of a tape by changing pressure contacting force of a pinch roller or changing pressure contacting angle of winding side of entrance of the tape according to normal or reverse driving of the tape. CONSTITUTION:At the time of normal reproduction, the pinch roller 9 is pushed by a pressure contacting lever 6 and turns around a support 10, and brought into pressure contact with a capstan 8 at a position shown by a solid line, and the tape is driven. At this time the pinch roller 9 is placed at a position where it cuts into the capstan 8. When the capstan 8 rotates in reverse direction under this condition, the pinch roller 9 is subjectes to force in the direction of escape and pressure contacting force becomes weak. To prevent decreasing of the pressure contacting force, a loading disk 5 is rotated in the direction of H, and the pinch roller 9 is shifted to a position shown by a dotted line to change pressure contacting angle, and the pinch roller 9 is made to cut into the capstan 8.

Filed: 1987-08-05
Abstract: PURPOSE: To ensure safe travel by checking the condition of a position switch, for starting forced deceleration at the terminal story, when the end point switch in the terminal floor is actuated; and limiting the maximum operational speed after abnormality is detected, and indicating warning. CONSTITUTION: The rationality of the action of a position detecting switch 9 is checked when a car 1 is stopped at the terminal floor and an end point switch S is actuated, by an elevator control device 11 having a terminal floor forced deceleration device. That is for example, in cases where the lower end point switch S is actuated, the down side of the switch 9 is operated and the up side is not operated, normality is judged, and abnormality is judged at the time of the inverse; in addition, the similar check is made when an upper end point switch is operated. When the abnormality of the switch 9 is detected, a rated speed is forcedly reduced by one stage to travel an elevator, and also the abnormality is indicated. Thus measures against failure can be taken early with service lowering suppressed to the minimum.

Title: Magnetic bubble transfer circuit
Inventor: HIROSHIMA MINORU
IPC: G11C19/08
Filed: 1982-11-10
Abstract: PURPOSE:To obtain practically sufficient bias margin even when a period lambda of a basic pattern is reduced in a magnetic bubble transfer circuit in which the direction Q of a gap (g) between basic patterns intersects the direction P of magnetic bubble transfer obliquely by specifying the ratio of height H of transfer pattern to period lambda. CONSTITUTION:When lambda represents the period of arrangement of the direction P of magnetic bubble transfer of a pattern 1b, and H represents the height of the pattern that intersects the direction of transfer at right angles, if ratio of the height H to the pattern period lambda R=H/lambda is changed from 0.5 to 1.0, a magnetic bubble transfer circuit is constituted to make the pattern 1b R>=0.7 as the bias magnetic field margin width DELTAHB becomes large. In this constitution, bias magnetic field margin DELTAHB twice as large as R=0.5 can be obtained by making R larger than 0.7. This is because bubble driving force when the bubble goes across the gap between patterns becomes strong by making R large.
