Filed: 1996-10-18
Abstract: PROBLEM TO BE SOLVED: To improve the secrecy function by selectively applying the inversion and non-inversion to the band signals which are separated into high and low frequency bands and then putting again these band signals together to transmit them. SOLUTION: The output signals of an LPF 10 are inputted to an LPF 11 and HPF 13 having the same cut-off frequency as the LPF 10. The low and high frequency band signals are inverted by the modulators 17 and 18 which are connected to one of both next stages of the LPF 11 and HPF 13 and sent to the switches S1 and S2. Thus the non-inverted low or high frequency band signals of the LPF 11 and HPF 13 and the inverted low or high frequency band signals of modulators 17 and 18 are selected and sent to the LPF 12 and 14. The low and high frequency band signals are acquired as outputs and added together by an adder 20. These signals are inverted by an LPF 15 and a modulator 19 and sent to an LPF 16. Then the signals which undergone the inversion or non-inversion by a switch S3 are sent to the receiving side as the secrecy circuit output signals OUT via a transmission channel.

CONSTITUTION:When a door start, opening, for example, a lock member 18 is retracted by a solenoid 19 whereby the lock of a moving body 10 is released. Simultaneously with this motion, operation of an actuating mechanism is transmitted to a driving member 12 against a return spring 15 by way of a flexible cable 6, and furthermore it is transmitted to the moving body 10 of an opening/ closing mechanism via an expansion elastic body 13. In consequence, since the moving body 10 shifts along a moving route 9, an open/close link 7 rises and rotates whereby a movable roof 3 is opened upward. At this time, an open/ close motion of the movable roof 3 operates as being delayed to an open/close motion of the door by means of expansion of contraction of the elastic body 13. Therefore, such trouble where the movable roof is opened or closed too early and comes into contact with people boarding or alighting eliminable.

Title: Multiplexing controller
Inventor: SHIRASAKA ICHIROU
IPC: G06F3/06
Filed: 1990-10-16
Abstract: PURPOSE:To use a waiting time until a head is positioned at an objective record for the control of an another magnetic disk by reading both a record number on a track and a head position corresponding to it at the time of transmitting a search command from a central processing unit, and calculating the head position at which the objective record is presumed to be positioned. CONSTITUTION:When the first record number is read by a record reading part 6, the number is compared with the objective record number stored in a record storage part 2 by a search comraring part 4. As the result of this comparison, when the numbers disagree, the objective head position at which the objective record is positioned is calculated from the head position from a head position reading part 5 and the record number at which the head is positioned at present while supposing that the record is prepared at equal intervals This objective head position is stored in a reconnect part 8, and used for deciding the period of the reconnection. Thus, a time until the head approaches the objective record (rotation waiting time) is used for operating the control of an another magnetic diSk.
