Filed: 1990-05-29
Abstract: PURPOSE:To provide the operation of a burner employing catalyst in a short time with an excellent exhaust gas characteristics by igniting an auxiliary burner port section with flame and burning there as the temperature of an auxiliary catalyst layer that is provided in an exhaust gas channel on the downstream side of a main catalyst layer is raised to temperature which is sufficiently active by using a sheath heater, etc. CONSTITUTION:Fuel (kerosene) is vaporized in a mixing chamber 4 and at the same time it is sent to an auxiliary burner port section 6 at the upper section after its premixing with sufficient air. At this time the flame is ignited by an ignition electrodes 7 and flame combustion is started there. At this time high temperature exhaust has flows to the upper section, and flows to the downstream side (rear face) via a communicating hole 8a and reaches an auxiliary catalyst layer 10 in the exhaust gas channel, raising the temperature of a main catalyst layer 8. At this time since the temperature of the auxiliary catalyst layer 10 is already sufficiently raised by a sheath heater B11, the gases CO, HC in the exhaust gas are purified as they pass through the communicating hole 10a and discharged from an exhaust gas hole 12. And at the auxiliary burner port section 6 flame is burned for a certain time, and when the temperature of the main catalyst layer 8 is raised to sufficiently active temperature (temperature over about 300 deg.C required) the supply of the fuel is once stopped so that the flame goes out and then the supply of the fuel is started again.

Title: Method for regenerating cold trap
Inventor: INOUE MASAAKI
IPC: B01D8/00
Filed: 1986-06-19
Abstract: PURPOSE:To regenerate a cold trap by forming a gas space in the cold trap, then heating liq. metallic sodium to dissolve a hydrogen compd. collecting in the cold trap, and reducing the pressure to remove the compd. CONSTITUTION:A liq. sodium surface 27 and the gas space 29 are formed in the cold trap 21. The liq, sodium is then heated to dissolve the hydrogen-sodium compd. (NaH) collected at the collecting part 43 of the cold trap 21. The pressure in the gas space 29 is subsequently reduced to a pressure lower than the hydrogen partial pressure in sodium, the hydrogen contained in sodium is separated from sodium by the difference in partial pressure from the hydrogen in sodium, and transferred into the gas space 29. The transferred hydrogen is removed from a pipeline 25 by operating a vacuum pump. Since the gas space 29 is formed in the cold trap 21, a liq. surface forming vessel is not required.

IPC: G08G1/0969
Filed: 1995-06-08
Abstract: PURPOSE: To provide a present location calculating system which can accurately discriminate that the vehicle having the system travels along a road connected to an expressing or an ordinary road. CONSTITUTION: A controller 18 calculates a virtual present location which is presumed to be the present location of the vehicle, based on the traveling azimuth and traveling direction of the vehicle, calculates candidate points which indicate whether or not the vehicle travels along a road by comparing the virtual present location with road data, and calculates the reliability indicating the certainty of the candidate points.  In addition, the controller 18 adds a prescribed numerical value to a discriminating value whenever the vehicle passes through a junction at a speed equal to or higher than a prescribed speed when the candidate point having the highest reliability exists on an expressway road while the vehicle travels by a prescribed distance after the vehicle passes through a junction of an expressway and when the candidate point corresponding to the candidate point having the highest reliability also exists along the expressing and, when the discriminating value becomes equal to or larger than a prescribed value, recognizes the position of the candidate point along the expressway as the present location of the vehicle.

Title: Ink cartridge
Inventor: SASAKI TOYOKI
IPC: B41J2/175
Filed: 1996-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent the remainder of ink on the outlet end surface of an ink supply port after the dispensation of ink and to eliminate the leak of the ink from the ink supply port at a time of the start of use by forming a taper to the inner peripheral inlet of the ink supply port of an ink cartridge housing the ink supplied to an ink jet printer. SOLUTION: A circular ink supply port 12a is formed in an ink cartridge having a box shape so as to piece the front wall thereof and a taper part 20 is formed at the inner peripheral inlet of the ink supply port 12a. The length (h) and angle θ of the taper part 20 and the length H of the ink supply port 12a are optimized on the basis of the viscosity of ink or the pull-out speed of seal rubber. By forming the taper part 20 to the inner peripheral inlet of the ink supply port 12a, the seal rubber 31 is separated from a taper top part 21 when pulled out of the ink supply port 12a and, therefore, the excessive ink going along the inner wall surface of the ink supply port 12a can be left on the taper top part 21 by viscosity and no ink remains on the outlet end surface 15 of the ink supply port 12a.

Title: Refrigeration cycle
Inventor: MOROHOSHI TSUNEJI
IPC: F25B1/00
Filed: 1988-06-10
Abstract: PURPOSE:To prolong a life time of an electric motor and make a small-sized motor through a reduction of energizing load when a compressor is energized by a method wherein a high pressure cushion tank is arranged in the midway of a bypassing pipe, a solenoid valve is arranged in a pipe before and after the tank, and a control over ON-OFF of the solenoid valve is carried out at the time of energization and during operation. CONSTITUTION:Solenoid valves 9 and 10 are closed during a stoppage of a compressor. The solenoid valve 9 is opened simultaneously with an energization and the solenoid valve 10 keeps its closed state. With this arrangement, discharged gas is flowed such that a part of gas flowing from the compressor 1 into an oil separator 2 is flowed into a high pressure tank 7, resulting in that an expansion of the discharging volume can be realized and then a reduction in load in case of energization can be accomplished. Since the solenoid valve 10 is kept closed, gas within the tank 7 may not be flowed to the low pressure side. After a specified period of time elapses after the compressor is energized, the solenoid valve 9 is closed (for 2 to 5 seconds until the compressor shows a rated number of rotation), and then a circulating amount of coolant in a main system of the coolant is prevented from being decreased. Operation for changing the solenoid valve 10 from its closed state to its opened state is carried out after a specified period of time upon executing a cooling operation under operation of a time limited relay or under a manual operation.
