Title: Automatic opening/closing mechanism of staircase cover
Inventor: SAKAMA SUSUMU
IPC: E04F11/00
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To make it possible to open and close the head of stairs by a staircase cover in automatic mode by interlocking the head is stairs with the up and down of a movable floor in a room provided with a movable floor. SOLUTION: A board-shaped staircase cover 51 is rockably supported on an axis A1 of a movable floor 17. The tip of the staircase cover 51 is connected to a fixed floor 19 with a connecting rod 52. When the movable floor 17 is adapted to fall down, a rotary motion will act on the staircase cover 51 in the direction marked with the arrow R51 by the connecting rod 52. When the movable floor 17 is laid out at the falling position below, the staircase cover 51 is horizontal, thereby closing the head 20e of a staircase 20b. When the movable floor 17 is located at a rising position, the staircase cover 51 takes up an erected posture and retreats from the upper space of the staircase 20b, which protects a resident from any possible disadvantage when moving upstairs or downstairs.

IPC: H03H3/02
Filed: 1977-12-07
Abstract: PURPOSE:To improve shock resistance of artificial crystal by continuously varying a growth speed at a constant period when growing the crystal. CONSTITUTION:With buffer (e) of artificial-crystal growing autoclave (c) taken as a boundary, the temperature of seed crystal (b) at the growth part and that of raw- material crystal (f) at the raw-material part can be varied independently; the growth part is held at a temperature of 350 to 400 deg.C, and the temperature of the raw-material part is varied periodically to change the growth speed periodically within the range of 1 to 5 microns. If the period of the temperature variation is too large, cutting the crystal into a vibrator causes dispersion, so that each vibrator can be uniform in terms of material by the method mentioned above. In addition, it is preferable to vary the temperature between 0 and 40 deg.C.

Title: Printed board of iron
Inventor: NAKAMURA MOTOHARU
IPC: H05K1/05
Filed: 1987-06-15
Abstract: PURPOSE:To improve adhesiveness between a resin layer and a steel plate by a method wherein a specific plating layer is applied to the surface of the steel plate and a chromate treatment is applied to the plating layer and a metal foil is laminated with the insulating layer between. CONSTITUTION:A plating layer 2 of one or two metals among Gr, Cu, Ni, Zn and Sn is formed on the surface of a steel plate 1 and a chromate layer 3 is formed on it and a metal foil 5 is laminated on the chromate layer 3 with an insulating layer 4 between to constitute an iron board. The steel plate with a thickness of 0.3-2.0mm is used. If the thickness is less than 0.3mm, heat radiation is not sufficient. If the thickness exceeds 2.0mm, satisfactory motor characteristics can not be obtained when the iron board is used as a magnetic path of a miniature motor. As for the composition of the steel plate, if only the heat radiation and the mechanical strength are to be considered, common steel is good enough. But, if the iron board is used as the magnetic path of the miniature motor, a silicon-steel plate containing 0.5-3. 5% of silicon is employed. One or two metals among Cr, Cu, Zn, Ni and Sn are applied to the surface of such steel plate with a thickness of 0.5g/m<2>-3.0g/m<2> by electrolytic plating and a chromate treatment is applied to the plating with a thickness of 10-100mg/m<2> in metal chrome conversion. With this constitution, adhesiveness between the resin layer and the steel plate 1 can be improved.

Abstract: PURPOSE:To obtain sufficient holding force and strong sealing performance by forming a fitting groove penetrating toward an outer diameter on the inner periphery of a side end part of an outer ring, providing a synthetic resin seal plate which fits the fitting groove to close an opening on a side part between the outer and inner rings of a bearing. CONSTITUTION:A seal plate 40 is made of wide-ranging material such as the synthetic resin of polyurethane and polyamide or the like according to the condition of use, and pressed against the side part of a bearing body 15 to abut an abutting face 43a on the inclined guide face 22 of the side end part 21 of an outer ring 20. When the seal plate 40 is further pressed in, a protruding part 43b is brought into sliding contact with the inclined guide face 22 to guide an abutted end 43, and an elastic fitting part 41 outward from a neck part 42 deforms to advance inward, and fits into the inner periphery of the outer ring 20. When the seal plate 40 is sufficiently pressed in, the elastic fitting part 41 fits in a fitting groove 23 of the outer ring 20, and the energized end 44 of the elastic fitting part 41 strikes against a side face 23b to bend and stops. When the seal plate 40 is released, the elastic fitting part 41 is abutted on inner and outer side faces in the fitting groove 23 by the elastic repulsing force of the energized end 44 to be brought into pressure contact with the fitting groove 23 of the outer ring 20 under proper elasticity.

Title: Dropout detection circuit
Inventor: SHIMAMOTO MASAMI
IPC: G11B7/00
Filed: 1987-06-11
Abstract: PURPOSE:To improve the error correction capability by using it as a dropout detection signal for a signal during a period of being still in a significant level even at the front edge of a 2nd detection signal being the result of a prescribed time of delay among the significant level period including the dropout period of a 1st detection signal. CONSTITUTION:A clamp circuit 21 and a comparator 22 constitute the 1st signal detection circuit 2 to obtain the 1st detection signal (c). Moreover, a one-shot circuit 31 forms the 2nd signal detection circuit to obtain the 2nd detection signal (d) and outputs a low level pulse at a prescribed time width T1 while using a leading edge of the 1st detection signal (c) to be inputted. That is, a reproducing signal read from a recording medium is clamped to obtain the 1st detection signal (c) binarized at a prescribed threshold value and the 2nd detection signal (d) is obtained by retarding the 1st detection signal (c) by a prescribed time width. While the 1st detection signal (c) is at a significant level, if the 2nd detection signal (d) is transferred to the significant level, the period from that point of time to the trailing edge of the next significant level of the 1st detection signal (c) is detected to obtain a dropout detection signal. Thus, the error correction capability is improved.
