Title: Frequency tuning device
Inventor: KOIZUMI TAICHI
IPC: H04B1/26
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce phase noise and to widen a dynamic range by alternately shifting the frequency of second local oscillation signals by the width of the 1/2 of a prescribed step in the frequency tuning device of a double superheterodyne system for varying and tuning the frequency of first local oscillation signals outputted from a first local oscillator by the prescribed step. SOLUTION: This frequency tuning device for which the first local oscillator 12 is constituted of a PLL synthesizer varies the frequency of the first local oscillation signals outputted from the first local oscillator 12 by the step of 200 kHz. Since the reception of the step of 100 kHz cannot be performed as it is, the frequency of the second local oscillation signals outputted from a second local oscillator 15 is alternately shifted by the width of 100 kHz, the multiplication number of a reference clock performed in the PLL synthesizer for constituting the first local oscillator 12 is reduced and the phase noise is reduced though it is the frequency tuning device of a wide dynamic range.

Title: Sealed battery
Inventor: NAITO MASAHIKO
IPC: H01M2/02
Filed: 1989-09-05
Abstract: PURPOSE:To restrain the generation of cracks caused by strain in welding and to prevent electrolyte leakage without increase in production cost by making the content of nickel in a laser welding part in a specified value or less. CONSTITUTION:A battery container 2 and sealing cover 3 fitted to the opening of the battery container 2 are made of nickel-containing iron, and the battery container 2 and the sealing cover 3 are sealed by laser welding. The content of nickel in the welded part is controlled to 8% or less. Since strain caused by melting in laser welding is decreased and no bumping is generated, alloy is smoothly formed in the melted part. Composition and crystal form in the melted part are made uniform and the strain of nickel and iron is restrained after cooled. Generation of pinholes and cracks in the welded part can be decreased.

Under a normal operating state, the refrigerant compressed by the compressor 1 is flowed from a condenser 3 to an evaporator 7 through the expansion valve 5, the first fluid is heated 1 under utilization of heat generated at the condensor 3, and the second fluid is cooled under utilization of cold heat generated at the evaporator 7. When there are a large amount of demands for hot heat and there is less amount of demand for cold heat, the refrigerant is not passed through the evaporator 7, but flowed through the low temperature passage 13 so as to heat the refrigerant within the second heat exchanger 14. In turn, when there are a large amount of demands for cold heat and there is less amount of demands for hot heat, the refrigerant is not passed through the condenser 3, but passes through the high temperature passage 10 and then the refrigerant is cooled within the first heat exchanger 11.

Inventor: AKIYAMA DAISAKU
IPC: C23F1/44
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To suppress the degradation in a solder peeling speed by limiting the compsn. of a peeling liquid. SOLUTION: This peeling liquid is used to peel tin and tin alloy from a copper base material and is an aq. soln. contg. 150 to 300g/l nitric acid, 5 to 25g/l iron ions, 2 to 20g/l chlorine ions and 10 to 500ppm iodine compd. as an iodine concn. If the nitric acid, iron ions and chlorine ions are respectively below the concn. ranges described above, the solubility power to the tin and tin alloy is too small. If the ranges are exceeded, the dissolution effect is so intensive that the smooth copper surfaces are not obtainable. The iodine compd. which liberates iodine or iodine ion in the peeling liquid suffices and includes sodium iodide, etc. The iodine in the concn. range described above is effectual in suppressing the degradation in the solder peeling speed and in suppressing the erosion of the copper base material.

Title: Gas-circuit breaker
Inventor: ASAKURA TAKAO
IPC: H01H33/91
Filed: 1989-09-06
Abstract: PURPOSE:To facilitate rise in pressure in a buffer cylinder, accelerate displacement of gas in the vicinity of an arc and improve breaking performance by generating a high temperature gas flow from the arc side into the buffer cylinder. CONSTITUTION:When an arc A between contacts 21 and 13 comes into contact with a runner 26, the coil 25 is excited, and due to interlinkage of its magnetic flux and the arc A, the arc A rotates at high speed so that SF6 gas is blown to have the arc cooled. Until the contacts 21, 13 separate from each other by a specific distance, high temperature gas flows from the arc A side into a buffer cylinder 18 resulting in a rise of pressure in the cylinder 18 so that the cylinder 18 is displaced with respect to a piston 19 along with displacement of the contact 21 to have a volume of the cylinder reduced. Therefore the pressure in the cylinder rapidly rises. When a throat part 22b1 of a nozzle 22 comes off the contact 13, closure of a space surrounding the arc A is released and the space in the cylinder is opened so that gas in the cylinder is blown against the arc A at high speed and the arc is cooled.
