Title: Optical transmitter
Inventor: HARIGUCHI MASAO
IPC: H04B10/80
Filed: 1983-04-26
Abstract: PURPOSE:To prevent unnecessary power consumption of a reception side device by controlling the on-off operation of a receiving power source by using a light signal transmitted from a transmission side device. CONSTITUTION:A light signal (a) after pulse-width modulation is inputted to a phototransistor PTR7, which turns on or off according to the light signal; a transistor TR8 is turned on while said PTR7 is on to charge a capacitor C14 from a power source terminal B2. The C14 is discharged while the PTR7 is off, but the discharge time constant is larger than the charge time constant, so the voltage of the C14 rises to turn on TRs 9 and 11; and a current is supplied from a power source B2 to a power source circuit 6 for reception and a voltage stabilized by the circuit 6 is supplied to a reception signal circuit 4. When the signal (a) is ceased, the PTR7 and TR8 turn off, the C14 is discharged to drop in voltage, and the TR9 and 11 turn off, so that no current is supplied from the power source B2 to the circuit. Therefore, no reception electric power is consumed while no light signal is transmitted.

Title: Alloy material
Inventor: ISOTANI TAKESHI
IPC: C23C8/26
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy material free from the generation of pitting and having a long service life by diffusing nitrogen having a specified conc. over the surface of an alloy material. SOLUTION: Over the surface of an alloy material such as a low alloy steel, nitrogen is diffused to so as to regulate the concn. of nitrogen to 0.1 to 1.0%. The depth of the diffusion of nitrogen from the surface of the alloy material is made deeper than a surface abnormal layer formed on the alloy material. In this way, its hardenability improves to suppress the formation of the surface abnormal layer and also to form carbon nitrides in the alloy material by which the bearing strength of the material can be improved. The alloy material preferably contains, by compositional ratio, <=0.15wt.% Si, <=0.55wt.% Mn, <=0.70wt.% Cr, >=0.50wt.% Ni and >=0.40wt.% Mo. By reducing the alloy components oxidized in the process of carburizing treatment, intergranular oxidation causing fracture cracking can be suppressed.  The reduction of this hardenability caused by the reduction of the alloy components can be suppressed by the addition of Mo and Ni.
