Abstract: A data transmission among the exchange modules in the building block type exchanger with improved efficiency, reliability and simplicity of implementation. An ATM connector is connected to the STM exchange module connector through at least one STM transmission line containing logical transmission paths provided in correspondence to the logical STM transmission path for transmission of specific data connected from each exchange module to the STM exchange module connector and fixedly switched by the STM exchange module connector to the logical transmission paths of the STM transmission line connected to the ATM connector. The specific data to be transmitted from each exchange module are transmitted in a form of ATM cells to the ATM connector, while all the specific data to be transmitted to each exchange module are multiplexed in a form of multiplexed ATM cells at the ATM connector and the multiplexed ATM cells are transmitted from the ATM connector to each exchange module.

Abstract: A radial tire for motorcycles which comprises: at least one carcass ply of organic fiber cords arranged radially at an angle of 85 to 90 degrees to the tire equator and turned up around the bead cores to form two turned up portions and a main portion therebetween; a tread disposed radially outside the carcass and curved so that the maximum cross section width of the tire lies between the tread edges; a belt disposed radially outside the carcass and inside the tread and having at least one spirally wound cord; and a bead apex disposed between the carcass main portion and each carcass turned up portion, wherein the belt is composed of at least one spirally wound cord having an elastic modulus of not less than 600 kgf/sq.

Abstract: A radial tire for motorcycles which comprises: at least one ply of radially arranged organic fiber cords turned up around the bead cores to form two turned up portions and a main portion therebetween; a tread disposed radially outside the carcass to define the tread portion; sidewalls disposed axially outside the carcass to define the sidewall portions; a belt disposed radially outside the carcass and inside the tread; a bead apex disposed between the carcass main portion and each carcass turned up portion and extending radially outwardly and taperingly from the bead core; the radial height of the radially outer edge of each carcass turned up portion being 0.3 to 0.5 times the radial height of the tread edge, both from the bead base; the radial height of the radially outer edge of each bead apex from the bead base being 0.3 to 0.5 times the radial height of the tread edge; the belt composed of at least one spirally wound cord having an elastic modulus of not less than 600 kgf/sq.

Abstract: Apparatus for monitoring the cage of an elevator for crime prevention including a connection establishing two-way voice communication between a telephone/television within the elevator cage and a similar device at a remote monitoring point. Communication is automatically established in response to a signal, such as generated by elevator call buttons, utilized in operation of the cage.

Abstract: A motorcycle tire improved in running stability under low pressure service conditions characterized in that:when the tire is mounted on a regular rim and inflated to 15% of the maximum pressure, the ratio (A/B) of the tire section width (A) measured at the same radial height as the carcass maximum section width point (p) at which the section width of the carcass is maximum to the bead width (B) is not less than 1.90 and not more than 2.20;a middle portion (C) of the carcass profile defined between a point (W1) and a point (W2) is formed by an arc (Sc) having a curvature of a single radius (Rc) and having a center (o1) inside the tire; anda radially inner portion (U) of the carcass profile defined as extending from the radially inner point (W2) to the bead base region is formed by an arc (Su) having a center (o2) outside the tire and having a curvature of a single radius (Ru) smoothly connected to the above-mentioned arc (Sc) at the point (W2) as a point of inflection therebetween.

Abstract: A process for preparing a crack-free, dried collagen sponge having a shrinkage factor of up to 14%, including the steps of impregnating crosslinked collagen sponge with an aqueous solution of a hydrophilic organic solvent, freezing the sponge at a temperature of -80.degree. C. or lower, and vacuum-drying the sponge.

Abstract: A rescue operating apparatus for an elevator has a device for transmitting a cage door open/close command from an elevator supervising section which receives notice regarding the trouble of the elevator and the stopping of the cage between floors, and an operation control device for controlling a door driver on the basis of a door open/close command from the command transmitting means to open/close the cage door thereby to confirm the full closure of the door and then control the elevator driver, thereby performing the rescue operation of the cage.

Abstract: An elevator remote-control method according to this invention consists in that, when a maintenance command has been received, a call-back program is executed which comprises a ring-off processing step of once disconnecting a telephone circuit, and a reconnection step of dialing a remote monitoring center to reconnect the telephone circuit, whereupon a program which conforms to the maintenance command is executed.

Abstract: A method of and apparatus for controlling operation of an elevator at the occurrence of an earthquake. Estimated seismic intensity data is collected from a plurality of sources at different locations within a geographic region and transferred to an administration section; the geographic region is divided into zones of different seismic intensity based upon the transferred data; seismic intensity at the location of the elevator is assumed upon the occurrence of an earthquake on the basis of location of the elevator in the zones; whether the operation of the elevator is to be permitted is judged according to the assumed seismic intensity; and a trial run is commanded upon a judgement that operation is permitted, whereupon normal elevator operation is restored when the absence of any abnormality has been acknowledged upon travel during the trial run.

Abstract: A control apparatus for an elevator comprises a position detector responsive to cage movement, a non-volatile semiconductor memory for storing representation of cage position, and a microcomputer operated under program control for controlling the position detector to produce signals representing instantaneous cage positions and for continuously erasing and rewriting the contents of the non-volatile semiconductor memory based on the position detector signals. Thus, the stored contents can be reliably held even at the time of power failure, so that an expensive backup power source can be dispensed with.
