IPC: H01L33/00
Filed: 1985-11-06
Abstract: PURPOSE:To equalize the distribution of the amount of light by mounting a selecting circuit selecting compensating data memorized in a memory means and a compensating circuit controlling a drive circuit on the basis of the selected compensating data. CONSTITUTION:A memory means 3 is constituted of three ROMs 3a-3c, each ROM previously memorizes compensating data corresponding to the time characteristics of an LED array 5, and predetermined compensating data are used for compensating the amount of light. Signals are outputted by a conduction timer 7 every time the LED array 5 is conducted for a fixed time, and the ROMS 3a-3c are selected by changing over a selector 8. The selected compensating data are inputted to a compensating circuit 2, a picture signal is compensated on the basis of the compensating data, and a compensating signal is outputted to a drive circuit 4. Power inputted to the drive circuit 4 is controlled by the compensating signal, and fed to the LED array 5. Accordingly, even when the distribution of the amount of light of each element for the LED array changes, the dispersion of the amount of light corresponding to the change sections is compensated, thus keeping the distribution of the amount of light uniform at all times.

Title: Working method for ceramics by laser beam
Inventor: KUWABARA TAKASHI
IPC: B23K26/00
Filed: 1993-10-04
Abstract: PURPOSE:To reduce the sticking of debris, and keep a working surface smooth by selecting a laser energy density in a range where the laser energy density on the surface to be worked of a composite sintered body is an abrasion threshold value or more and the coarsening of grains after the melting and the solidification on the working surface, is few. CONSTITUTION:For instance, the energy density of a KvF laser beam 10 irradiating on the AlTiC plate 1, is selected to approximately 1J/cm<2>. This energy density is a little higher than a threshold value to the extent that the threshold value can be secured even in the case of a fluctuation. The smoothness of a worked bottom surface with subjected to an abrasion work, is satisfactorily kept by an energy density with a low value like this. Also, since a melted layer on the worked surface of the AlTiC plate, is thin and a cooling speed is fast, the coarsening of grains, is few by resolidification. Also, since the mass of splashed matters, is small, the generation and the attachment of debris in a working area, is few. Further, since the energy density is low, an increase in temperature of the AlTiC plate, is suppressed, thermal strain is lower, and the development of a cracking, is remarkably reduced.

Title: Address conversion method
Inventor: TAKAHASHI HIROMASA
IPC: G06F12/10
Filed: 1990-09-20
Abstract: PURPOSE:To improve the performance of the entire address conversion system by retrieving the conversion table of the first storage means to obtain an entry address, by using the entry address to retrieve the conversion table of the second storage means, and by converting a logical address into a physical address so as to carry out address conversion by means of relatively simple control at high speed. CONSTITUTION:Since processor 1 is provided with part of a multi-stage conversion table, if a conversion table entry corresponding to a logical address calculated in the processor 1 is not present in the address conversion system, address conversion as far as an intermediate stage can be done within the processor 1. Since the address conversion can be finally done only by retrieving the conversion table in the main memory 2, the number of times of accessing the main memory 2 can be considerably reduced. With this, address conversion can be carried out at high speed, thereby contributing to the improvement of the performance of the entire system.
