Patent JP-H0798132-A (JP)
Title: Ice heat accumulator
Inventor: HIDA YOSHINORI
IPC: F24F5/00
Filed: 1993-09-30
Abstract: PURPOSE:To form such a state that return water flows strongly in an ice heat- accumulating tank for a long time without flowing quickly to the side of expelling, by providing the jet of a cold-water return pipe at an upper underwater part in the ice heat-accumulating tank, pointing to horizontal direction. CONSTITUTION:The jet of a cold-water return pipe 5a is located at the upper part under a waterlevel 2, pointing to almost horizontal direction at one of the walls of an ice heat-accumulating tank 1. In this way, the cold-water return pipe 5a horizontally injects a jet stream 6 consisting of return water, pointing to ice lumps 3 in the ice heat-accumulating tank 1. The heat of the jet stream 6 is exchanged in the ice lumps 3 and melts the ice lumps 3. At the same time, the jet stream 6 peels the ice lumps 3 from the walls and takes the ice lumps 3 to pieces in the limits where the jet stream 6 diffuses. Since the jet stream with a higher temperature is in direct contact with the ice lumps, at the part with max. temperature difference, the jet stream effectively receives the latent heat of ice. Furthermore, since the jet injects the jet stream horizontally, an area where the jet stream is in contact with the ice lumps lengthens and since the jet stream takes the ice lumps in pieces, the contact area of the ice to water increases. In this way, the efficiency of heat accumulation is sharply improved.

Title: Confirmation system of opposite communication party
Inventor: HAGIWARA TAKASHI
IPC: H04M1/665
Filed: 1989-09-20
Abstract: PURPOSE:To eliminate the need for the registration and to simplify the registration when a memory capacity is exceeded by providing a means writing a transmission destination ID to a memory automatically at transmission and a comparison means or the like and registering automatically the memory content taking the coincidence at the reception. CONSTITUTION:A memory 3 is provided, which stores a opposite communication party destination terminal equipment identification code(ID) and stores the ID sent from a transmission destination to the memory 3 automatically by using a write means 11 at the transmission. Then the ID is compared with an ID read from a comparison means 2 and sent from the transmission destination at the reception and the result is informed in a CPU in the communication control section 1. The control section 1 receives a data when the opposite ID is registered already in the memory 3 based on the result of comparison and stops the reception when the ID is not registered. Moreover, as the result of new ID registration, when the memory capacity is exceeded, the CPU registers a new ID to a storage area of the ID with least frequency of use. Thus, the content of the memory taking coincidence at the reception is registered automatically to eliminate the need for the registration and the registration in excess of the memory capacity is simplified.

Title: Type ground speed meter for vehicle ultrasonic doppler
Inventor: NEGISHI MASAMI
IPC: G01S15/52
Filed: 1989-09-22
Abstract: PURPOSE:To obtain an excellent measuring precision for an entire speed range by using an ultrasonic reception signal containing a Doppler shift component and a reference signal for inputs of a phase comparing means, by making a voltage control oscillation means deliver an output on the basis of an output of the comparing means and by driving an ultrasonic transmission means thereby. CONSTITUTION:In a PLL circuit constituted of phase comparing and voltage control oscillation means, an output frequency of a voltage control oscillator 11 is controlled so that both input signal frequencies of a phase comparator 8 be the same. The frequency fr of an output signal of the oscillator 11 is controlled so that a frequency fR of a reception signal containing a Doppler shift component be in accord with a frequency fREF of a reference signal. When an ultrasonic wave is emitted in the direction of advance of a vehicle, fR becomes larger than fr by a rate corresponding to the speed of the vehicle, while fR is so controlled as to be equal to the prescribed fREF, and therefore fr becomes small by the Doppler shift component corresponding to the speed of the vehicle. When the Doppler shift component is denoted by fD, fREF = fR = fr + fD, and the speed of the vehicle is determined therefrom. According to this constitution, an excellent measuring precision can be obtained for an entire speed range.
