Title: Decoder circuit
Inventor: AIZAKI AKANE
IPC: G11C11/413
Filed: 1989-12-26
Abstract: PURPOSE:To decrease the number of elements and to reduce the mask area and load capacity by composing the decoder circuit of a specific two-input logic element. CONSTITUTION:When an address is inputted to a memory, an address buffer circuit and a decoded signal generating circuit generate decoded signals Ai and Bi. One signal Ai is at 'H' level and others are all at 'L' level. One signal Bi is at 'L' level and others are all at 'H' level. The P channel transistor Tr Q11 of the two-input logic element 11 is invariably in the ON state since the gate is grounded. Consequently, when Tr Q11 is less in ability than Q12, a node N11 is at 'L' level and WORDk is at 'H' level only when the Q12 is ON and the Bi is at 'L' level. Consequently, only one word line is at 'H' level and others are all at 'L' level, so one line is selected. Therefore, the mask area and load capacity are reduced as compared with the configuration of a two-input AND circuit and a NOR circuit.

Title: Discharge lamp device
Inventor: KATAOKA KENJI
IPC: F21S2/00
Filed: 1989-12-28
Abstract: PURPOSE:To increase the heat conduction between a lighting device part and an envelope by absorbing the generated heat of the lighting device part on one side of a heat pipe, and transporting this heat to the other side of the heat pipe to release it through the envelope. CONSTITUTION:A lighting device part 2 is heated by the lighting of a discharge lamp to heat one side 5a of a heat pipe 5. This heat quantity is lost as a vapor latent heat when a working fluid in the one side 5a of the heat pipe 5 is heated and evaporated, and the vapor of the evaporated working fluid moves to the other side 5b of the heat pipe 5 by utilizing the vapor pressure of itself. The vapor pressure of the working fluid moved to the other side 5b is cooled by an envelope 3. At that time, the vapor of the working fluid is condensed and returned to liquid, while the condensed latent heat is released to the envelope 3, and thus the heat of the lighting device part 2 is released to the envelope 3. The heat conducted to the envelope 3 is, in turn, released to the circumferential air.
