Title: Electric power device
Inventor: MOCHIZUKI SHOJI
IPC: H01R12/04
Filed: 1989-06-12
Abstract: PURPOSE:To improve the reliability of a base by making the form of terminals of a power module in tab terminals, inserting the tab terminals in penetration holes provided at the printed base, soldering some of the terminals to a copper pattern on the base, and generating the other terminals through the holes to connect directly to the opposite terminals. CONSTITUTION:Tab terminals 22 for base current of a power module 2 through which only a small current flows are connected to a base amplifier circuit (not shown in the figure) on a base 1 directly with a copper foil pattern on the base 1 through no lead wire, and tab terminals 21 for DC power source are also connected to a DC circuit (not shown in the figure) on the base 1 directly with the copper foil pattern on the base 1 in the same manner. Tab terminals 23 for three-phase current output of the module 2 through which a large current flows are connected directly to receptacles 3 for output installed to the lead wires of a load such as a motor, passing through terminal insertion holes 4 provided at the base 1 without passing through the copper foil pattern on the base 1. By such a constitution, a pattern and terminals for a large current are omitted on the base 1.

Title: Double-effect absorption type refrigerator
Inventor: KUROSAWA MOKICHI
IPC: F25B15/00
Filed: 1989-06-12
Abstract: PURPOSE:To prevent refrigerant steam from being absorbed to dilute liquid of a low tempera ture reproducer even when a flash is effected and to enable execution of stable operation by providing a pressure uniformizing pipe through which the gas phase part of a mixing tank is connected to a condenser. CONSTITUTION:Refrigerant steam from a high temperature reproducer 1 is separated by a dilute liquid separator 2, dense liquid is guided through a high temperature heat exchanger 4 to a mixing tank 6, and intermediate concentration liquid from a low temperature reproducer 3 is guided to the mixing tank 6. The dense liquid and the intermediate concentration liquid are mixed together in the mixing tank 6 to produce mixture dense liquid, which is sprayed over the heat transfer pipe of an absorber 10 after the flow of it through a low temperature heat exchanger 5 to form a refrigeration cycle. In this case, the temperature of dense liquid flowing out from a high temperature heat exchanger 4 is higher than the saturated temperature of a pressure in the low temperature reproducer 3. In which case, even when a flash is effected in the mixing tank 6, since a gas phase part 6a of the mixing tank 6 is connected to a con denser 8 through a pressure uniformizing pipe 9, refrigerant steam generated in the mixing tank 6 is condensed in the condenser 8 to produce condensate, which flows to an evaporator 12. This constitution prevents refrigerant steam from being absorbed in dilute liquid in the low temperature reproducer even when a flash is effected, and enables execution of stable operation.

Title: Exhaust emission control device for internal combustion engine
Inventor: TAKAHASHI TOSHIKATSU
IPC: F01N3/28
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To accurately detect the deterioration of a NOx controlling means independently of change of operating condition and degree of deterioration in the case where a three-dimensional catalyst is provided. SOLUTION: In an exhaust system of an internal combustion engine for combustion at a lean air-fuel ratio, a three-dimensional catalyst 1, a lean NOx catalyst 2, and a CO sensor 3 are arranged in this order from the upstream to the downstream of the exhaust system. The output from the CO sensor 3 is fed to an ECU. A deterioration detecting means for ECU determines the degree of deterioration of the lean NOx catalyst 2 on the basis of the CO concentration detected by the CO sensor 3. For example, in the case where the peak value of the CO concentration detected in the rich spike is higher than the predetermined critical CO concentration, since the degree of deterioration is large, the deterioration is determined.
