Title: Amorphous iron alloy with resistance to pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement
Inventor: MASUMOTO TAKESHI
IPC: C22C38/36
Filed: 1982-11-15
Abstract: PURPOSE:To obtain an amorphous Fe-Cr-P alloy with superior resistance to pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement by specifying the amounts of Cr, C or B, P, and C+P or B+P in an Fe-Cr-P alloy. CONSTITUTION:A molten alloy is sprayed on the inside of a drum rotating at a high speed in an inert atmosphere and cooled at a very high cooling rate to obtain an amorphous alloy. At this time, the alloy is composed of, by atom, 1- 40% Cr, 2-30% C or B, 5-33% P (C+B or B+P=7-35%) and the balance Fe. In case of less than the lower limit of Cr, the resistance to pitting corrosion, crevice corrosion, stress corrosion cracking and hydrogen embrittlement is deteriorated, and in case of more than the upper limit of Cr, it is difficult to manufacture the amorphous alloy. Only when the amounts of C or B, P, and C+ P or B+P are within said ranges, the amorphous alloy can be manufactured.

IPC: H04M1/60
Filed: 1990-07-27
Abstract: PURPOSE:To eliminate the strange feeling of a speaker by executing regulation that a trunk line speech level exceeds an extension speech level. CONSTITUTION:For a reception amplifier 70, the level of the output signal is automatically adjusted by adjusting the level of an input signal according to an output from a detection circuit 50. The reception amplifier 70 amplifies an inputted reception signal at a prescribed amplification factor and afterwards outputs the signal, and the detection circuit 50 regulates that the trunk line speech level exceeds the extension speech level by adjusting the level of the reception signal to be inputted to the reception amplifier 70 while receiving an output signal V1 from the reception amplifier 70 so that the level of the output signal can not exceed the previously set threshold level of the reception signal. Thus, any strange feeling is not applied to the speaker.

Title: Train ticket collection device
Inventor: KOMORI MIKI
IPC: G07B15/00
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To prevent a collected train ticket from being reused by providing an embossing mechanism which embosses a train ticket in a collection conveyance path through which a train ticket that need not be returned is collected. SOLUTION: When a controller decided that a train ticket is a train ticket to be collected, the train ticket is conveyed by the collection conveyance path and a couple of embossing belts 10 and 11. Consequently, the train ticket has the entire top and reverse surfaces embossed by the couple of embossing belts 10 and 11 while conveyed. Thus, the ticket which is collected in the collection box B is stored through the embossing mechanism E, so train tickets which are collected are all embossed. Therefore, the embossed train tickets are easily found as waste tickets and the train tickets which are collected in the collection box B are effectively prevented from being used again.
