Abstract: PURPOSE:To save the electric power in a DC drive mode and to increase the useful life of a device main body by performing a switching action to supply selectively the electric power to a part or the whole of a load as interlocked to a loading action of a case to the device main body. CONSTITUTION:A case contact 7 is moved to a position shown by a dotted line from a position shown by a solid line and connected to a contact 10 of a device main body. When a slide switch 3 is turned on, the power is supplied to all of loads 11, 12 and 14 from an AC converter 23 consisting of an AC power supply and a rectifier. Therefore the power is supplied to all loads in case an AC drive is carried out with an AC adaptor incorporating the converter 23 loaded to the main body 2 of a video tape recorded. When a battery case 1 is fitted, the switch 3 is turned off to supply the power to a load 14 excluding an RF output circuit 11 and a heater energizing circuit 12. As a result, the power consumption is reduced to increase the useful life of a battery.

Title: Window opening/closing device
Inventor: OHIRO NORITAKA
IPC: E05F15/10
Filed: 1996-06-07
Abstract: PROBLEM TO BE SOLVED: To provide such a window opening/closing device which judges foreign matters to be held in and interrupts the opening/closing operation of a window glass as being capable of causing no hold-in misjudgement resulting from a door with time window glass to be opened/closed. SOLUTION: A rotating number sensor 29 generates pulses at cycles corresponding to the speed of a motor and a pulse cycle calculating part 32 calculates the pulse cycles. A hold-in estimating part 36 calculates the load of the motor in accordance with the pulse cycles and estimates foreign matters to be held in when the load exceeds a preset threshold value. If the foreign matters are estimated to be held in, a drive control part 40 stops the drive of the motor and then controls reverse run to release the foreign matters held in. On the other hand, a door opened/closed detecting part 34 detects the door to be opened/closed operation and a prohibiting control part 38 prohibits hold-in estimation for a preset time after the door is opened/closed. In this way, misjudgement resulting from the door to be opened/closed is prevented.

Title: Brazing method of aluminum and aluminum alloy
Inventor: MIYAMA KATSUMI
IPC: B23K1/19
Filed: 1994-06-03
Abstract: PURPOSE:To obtain high joining strength by executing further diffusion/annealing treatment after joined with using the brazing filler metal of specific composition to braze between one member made of aluminum or aluminum alloy and other member made of aluminum alloy or ceramic. CONSTITUTION:In the brazing method, in which a brazing filler metal having a principal component of Al, Si, Cu is sandwiched between one member made of aluminum or aluminum alloy and the other member made of aluminum alloy or ceramic, a brazing filler metal has a composition consisting, by atomic % substantially, of 4-6.5% Si, 12-16% Cu and the balance Al. Also, after this brazing filler metal is sandwiched and then joined, it is subjected to diffusion/ annealing at a temp. lower than a solidus of the brazing filler metal. By this method, because a joined body, which suppresses presence of brittle intermetallic compound, is obtained by using Al-Si-Cu alloy having low melting point for brazing filler metal, Al-Si casting alloy, for which brazing is impossible, can be brazed.
