Title: Passive noise eliminating device
Inventor: KURISU KIYOHIRO
IPC: F01N1/00
Filed: 2001-04-16
Abstract: PROBLEM TO BE SOLVED: To allow a control system to securely return to its normal state when becoming abnormal. SOLUTION: Noise such as an exhaust sound propagated in an exhaust duct 1 is canceled by causing a control sound which is substantially as loud as the noise and opposite in phase to interfere with the noise. In this control system, a system control part 7 reads a previous filter coefficient before the error level E detected by an error level detection part 7 increases out of a storage part 8 and sets the coefficient to an adaptive filter 31 in an adaptive control part 3 a when the error level E tends to increase. If the error level E still increases even after the filter coefficient is thus replaced, the system control part 7 clears the filter coefficient of the adaptive filter 31 and also controls the adaptive control part 3 so that a secondary sound path C is identified again. Consequently, the control system securely returns to its normal state.

Title: Data gathering system for collecting load
Inventor: HATTA TAKUYA
IPC: G06Q30/04
Filed: 2001-04-24
Abstract: PROBLEM TO BE SOLVED: To solve the problem of missing the requested delivery date and time, which is caused by delayed turning over of collected loads to a home- delivery company by an agent who turns over the loads once in the evening, therefore, the collected loads must be separated to transport from the agent to the company several times in a day since the agent collects the goods in a small quantity by visiting a client location with a bicycle. SOLUTION: A data gathering system stimulates a collection of loads as early as possible by setting the most inexpensive rates for a time zone when a collection of loads is hardly asked for such as right after offices are opened in order to solve the above problem. The data system, then, enables an agent to effectively collect the goods by setting the most expensive rates for the time zone just before the office closing time, to avoid a concentration of the collection of the loads. Furthermore, the system enables the agent to schedule a patrol path and allocate a vehicle by asking user to input the user's address, a recipient address, a type of the load, and a quantity of the loads when the system receives the collection order of the loads.

Title: Ejector cycle
Inventor: TAKEUCHI HIROTSUGU
IPC: F25B1/00
Filed: 2001-04-25
Abstract: PROBLEM TO BE SOLVED: To improve the refrigeration capacity (endothermic capacity) at least in a vaporizer. SOLUTION: A mixed refrigerant is employed as a refrigerant in the ejector cycle. The change of refrigerant discharged from a nozzle 410 (ejector 400) takes place isentropically, so that dryness of the refrigerant immediately after the reduced pressure becomes small. Accordingly, a gas-liquid two-phase refrigerant of low dryness can be supplied to a gas-liquid separator 500.  Further, although when liquid phase refrigerant is supplied to the vaporizer by the gas- liquid separator, in this case gas-liquid two-phase refrigerant of a low dryness is supplied to the separator, so that the rate of the gas-phase refrigerant, contained in the refrigerant supplied from the separator to the vaporizer, becomes small; and as a result, the range of variation of a pressure loss generated in supply of the refrigerant from the separator to the vaporizer becomes small, and the change in the refrigerant temperature (vaporization temperature) in the vaporizer can be reduced.
