Filed: 1991-09-04
Abstract: PURPOSE:To obtain a high toughness and high ductility TiAl intermetallic compd. by specifying the volume fraction of pro-eutectoid TiAl phase in the metal texture of a TiAl intermetallic compd. composed of heat-treated TiAl phase and the pro-eutectoid TiAl phase. CONSTITUTION:The metal texture of a TiAl intermetallic compd. is composed of matrix phase having heat-treated TiAl phase gamma and Ti3Al phase and pro- eutectoid TiAl phase gamma' dispersed in the matrix phase and the volume fraction of the pro-eutectoid TiAl phase gamma' is regulated to <=40%. Thus, the toughness and ductility of the TiAl intermetallic compd. can be enhanced. The pro- eutectoid TiAl phase gamma' deposits during cooling from a molten state, has a higher Al concn. than the heat-treated TiAl phase gamma, is brittle owing to the higher Al concn. and adversely affects the toughness and ductility of the TiAl intermetallic compd. When the volume fraction of the phase gamma' exceeds 40%, the toughness and ductility of the TiAl intermetallic compd. deteriorate.

Title: Stabilizing method of solar battery output and stabilized solar battery
Inventor: ASAOKA KEIZO
IPC: H01L31/04
Filed: 1991-09-02
Abstract: PURPOSE:To stabilize the output of an amorphous solar battery in a short time by decreasing the output current of a solar battery under a simulating sun to 95% and below of the former output in the forward direction of the solar battery. CONSTITUTION:The output of an amorphous solar battery 1 depends also upon its structure or conditions of manufacture but it us normally stabilized under the sun when about 10 to 50% of the initial output lowers. For the purpose of controlling the output variation of the solar battery 1 to 5% and below, it is sufficient to decrease about 5 to 45% of the initial value of the output beforehand by current injection. Therefore, it is sufficient to cause a current to flow in the forward direction until the output of the solar battery 1 lowers to a suitable value of 95% and below of the initial output which value is determined by the solar battery 1. Said value is 10OMEGA and below per unit area of the solar battery 1. Thus, it is possible to stabilize the output of the amorphous solar battery 1 in a short time.

Filed: 1984-11-29
Abstract: PURPOSE:To obtain a refractive index distribution-type lens having low aberration, by immersing a glass in a molten salt to effect the ion-exchange, and reheating the glass to cause the re-diffusion of the ion. CONSTITUTION:A distributed refractie index flat microlens 1 having a semicylindrical refractive index distribution zone 2 is produced as follows. A film impermeable to ion such as titanium film is applied to the surface of a glass plate 3 as a mask 4 having a slit opening 5, and the glass is dipped in a molten salt containing ions casing high refractive index such as silver, thalium, etc. The glass plate subjected to the ion exchange is heat-treated in an atmosphere (e.g. air) inert to the ion exchange between the glass and the atmosphere. The ions in the glass plate 3 are diffused by the heat-treatment in a manner to change the refractive index distribution of the glass to a distribution ideal as a lens. The surface mask 4 is removed from the glass plate 3 having the refractive index distribution zone, and the plate is polished t obtain a distributed refractive index flat microlens having low aberration.
