Title: Radio communication system and method, radio base station and radio terminal station
Inventor: TOSHIMITSU KIYOSHI
IPC: H04W84/12
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a multicast transmission system which can attain highly effective and reliable multicast transmission. SOLUTION: In this multicast transmission system, where a base station performs the broadcast transmission to plural terminal stations, a terminal station where an error is detected generates a NAK signal and transmits it to the base station by means of some of sub-carriers which form an OFDM symbol. A level-deciding part 25 of the base station retransmits a packet to every terminal station, only when a receiving signal level exceeds its threshold. The number M of sub-carriers which are available for generating the NAK signal and the number L of sub-carriers, which are necessary for generating the NAK signal are decided from the number of terminal stations, the communication quality, etc. For this purpose, both wrong detection probability and detection overlook probability of the NAK signal can be reduced.

Title: Destination story display device for elevator
Inventor: MIYAGI AKIRA
IPC: B66B1/14
Filed: 1990-10-15
Abstract: PURPOSE:To prevent confusion in a riding spot by collectively display controlling a story, where each elevator is determined to serve by a call assigning device, corresponding to a position of each elevator on a collective destination story display device. CONSTITUTION:When a 9-story destination button 7h is operated, for instance, in a 3-story riding spot, a condition of elevators No.1 machine 1 to No.6 machine 6 is input to a cage call assigning device 9. As a result, when the No.1 machine 1 is judged optimum assigned relating to a call by the destination story button 7h, a No.1 machine assigning call 11 is output. In a display control device 10, the 9-story destination call outputs information of an effect with the No.1 machine serving to a collective destination story display device 8 with information for displaying the No.1 machine 1 to No.6 machine 6 elevators like a map. Accordingly, the elevator to serve for the own desired destination story can be easily found out by the collective destination story display device 8. In this way, confusion in a riding spot can be prevented.

Title: Accumulator
Inventor: SEKIGAMI KAZUO
IPC: F25B43/00
Filed: 1988-11-02
Abstract: PURPOSE:To prevent liquid from being sucked by a compressor and foam from being sucked when foaming occurs even if a tubular accumulator is horizontally placed, by a method wherein a portion of a compressor side pipe is arranged at a piston lower than that of an evaporation side pipe in the accumulator, and small holes leading from inside to outside are provided on the compressor side pipe. CONSTITUTION:A tubular accumulator is nearly horizontally installed. A compressor side pipe 10 is inserted into the accumulator through one end and arranged so that portion of the pipe is located at a position lower than that of an opening of an evaporation side pipe 9 that is connected to the other end. One or more small holes 11 leading from inside to outside are provided on the lower portion of the pipe 10 so that a horizontal type tubular accumulator can be in practical use. The pipe 9 from an evaporator and the pipe 10 from a compressor are respectively connected to the outer shell 8 of the accumulator. When liquid is returned from the evaporator, the liquid is retained in the lower portion of the accumulator, and gas is sucked into the opening of the pipe 10 connecting to the compressor, thus gas-liquid separating takes place. The liquid 12 retained in the lower portion is sucked through the small holes 11 and turned into fine liquid particles 14 that are sucked by the compressor, so that direct compression of liquid is prevented.

Title: Data transmission apparatus
Inventor: FISHER DAVID ANTHONEY
IPC: H04L7/04
Filed: 1986-11-19
Abstract: In a data transmission system data is sent, after suitable conversion, as a ternary analogue type signal. Using two-wire twisted pairs and hybrids, echo cancellation and feedback equalization are needed. Synchronization between the two ends, e.g. of a 144 Kb/sec. subscriber's loop, is maintained by a low amplitude pilot tone sent with the data, which is detected at the same time as the data is detected. Detection and elimination of this pilot tone use coefficient generation circuitry similar to those used in the equalizer and echo canceller. To reduce the effect of time phase steps on the system performance, in addition to the transmission of a specific zero valued frame synchronization word which immediately precedes the phase step, the incoming synchronization word is also aligned to this time so that the value of a symbol as received can be predicted, as for a synchronization word, the predicted value is given preference if there is a difference between that symbol's value as received and its predicted value. In addition, the location of the high-pass filters used in the system are specified, alternative methods of bit timing control are specified and advantageous realizations of the canceller and equalizer using tap interpolation are disclosed.
