Title: Metal halide lamp
Inventor: YONEZAWA AKIHIRO
IPC: H01J61/20
Filed: 1987-12-17
Abstract: PURPOSE:To suppress blackening of a tube wall so as to improve ultraviolet ray intensity maintenance factor by charging cadmium at the specified gram number ratio to iron in addition to the iron. CONSTITUTION:Electrodes 2, 2 provided in a light emitting tube 1 are each connected to lead wires 5, 5 through metal foils 4, 4 sealed inside a crushed sealing parts 3, 3 of the light emitting tube 1. And rare gas for starting, mercury, iron and halogen are charged into the light emitting tube 1 and further cadmium of 1/40-1/2 at the gram atom number ratio to the iron is charged. If cadmium is charged additionally into the light emitting tube in advance like this, this cadmium reacts to the charged halogen and forms cadmium halide and further reacts on the isolated iron and changes it into iron halide. Hereby, tube wall blackening due to adhesion of iron to the tube inside wall is suppressed and lowering of an ultraviolet ray intensity maintenance factor resulting from the decrease of ultraviolet ray transmissivity by blackening and the decrease of iron being a light emitting metal can be prevented.

Title: Efficient distribution method for objects
Inventor: WATANABE KENJI
IPC: G06F9/44
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To improve the reliability, reusability and maintainability of an object- oriented software. SOLUTION: A data management mechanism is added to an object to collectively store and manage the data in every attribute of the object, e.g. the data are collected in a table form of a memory in every attribute value of the object. Under such conditions, a data management device deals with the object the same as conventional one in terms of its procedure. When the data on the object are accessed in the procedure, an object management part takes the data out of the data storage area of the memory and sends them to a program. When the processing is carried out over many objects, the occurrence of paging, etc., can be suppressed since the data to be referred to are collected together. Thus, the processing efficiency is improved.
