IPC: H01L21/28
Filed: 1989-04-28
Abstract: PURPOSE:To avoid contamination due to dust particles and a complicated process by a method wherein, after a TiN diffusion-preventive layer has been formed, an Al electrode layer is formed on it in succession without taking out this assembly into the atmosphere. CONSTITUTION:During a sputtering process of a titanium target 6, argon gas is introduced into a vacuum tank 1, and the titanium target 6 is sputtered. Thereby, a Ti layer is deposited on a silicon substrate 7. Then, while the argon gas is maintained as it is, nitrogen gas is introduced. At the same time, oxygen gas is introduced; its flow rate is controlled in such a way that it is increased from zero with the passage of time. The target 6 is sputtered under this condition; a TiN layer is deposited on the silicon substrate 7. After that, the silicon substrate 7 is conveyed to a vacuum tank 2 through a load lock 40 and is placed on a heating stage 92. While the inside of the vacuum tank 2 is being evacuated, argon gas is introduced, and direct-current electric power is supplied to an aluminum target 8. Thereby, a plasma of argon gas is generated; the target 8 is sputtered; an Al layer is deposited on the silicon substrate 7.

IPC: F16F9/18
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To reduce processing cost and parts cost by making unnecessary to use a female screw to a male screw portion formed on a rotation shaft. SOLUTION: A hinge mechanism 1 has a construction which provides a delayed operation by converting the rotating operation of a rotating shaft 4 coupled to the second hinge 12 into the operation in a linear direction. A rear end cylindrical portion 5c formed cylindrically near the rear end of the piston 5 is provided. At the rear end cylindrical portion 5c, one or more through-holes 5e are made in the peripheral wall portion, and a spherical body 6 which is exposed to the inside of the rear end cylindrical portion 5c and is able to contact a valley portion of the male screw portion 4b of the rotation shaft 4 is arranged in each through-hole 5e.  Thus, the rotating motion of the rotation shaft 4 can be converted to the operation in a linear direction through the spherical body 6 without forming the female screw for the piston 5 arranged through a whirl-stop mechanism in the coupling cylindrical portion.

Filed: 1992-04-30
Abstract: PURPOSE:To eliminate the useless waiting time and to improve the performance by setting the monitoring time to an appropriate value in accordance with the kind of various I/Os connected onto a bus. CONSTITUTION:For instance, when an address outputted from a CPU is '10H', '10'H is outputted as data from a decoder 12. When the value is loaded to a counter 11 and counted by synchronizing with a clock, an INT signal is outputted after the lapse of 1.6ms from the counter 11. Subsequently, when the CPU makes an access to the I/O of an address '20H', data '20'H are outputted from the decoder 12. The '20'H are supplied and loaded to the counter 11 as load data, thereafter, its counting is started by synchronizing with a clock and the INT signal is outputted after the lapse of 3.2ms from the counter 11. By setting a value obtained by dividing its time with a counting clock to the decoder 12 in advance based on the response time of each I/O, the monitoring time can be optimized.

Title: Power consumption reducing system for computer
Inventor: OKADA KUNIHIRO
IPC: G06F1/32
Filed: 1988-05-11
Abstract: PURPOSE:To reduce the power consumption in an HALT mode (mode for reducing the power consumption in a holding state) without decreasing an operation processing speed by providing an interruption commanding circuit which is started by a start signal which has been outputted from a processor, outputs an interrupting signal to the processor after a prescribed time and releases a low power consumption mode of the processor. CONSTITUTION:When an operation processing is all ended, a processor 1 outputs a start signal 6 and starts an interruption commanding circuit 2, and thereafter, becomes an HALT mode. After a prescribed time, the interruption commanding circuit 2 outputs an interrupting signal 5, and release the HALT mode of the processor 1. In such a way, the interruption can be controlled so that it is generated only at the time releasing the HALT mode, and it is not generated in the course of the operation processing, therefore, it does not occur that an operation processing speed of the processor 1 is decreased. Also, since the interruption commanding circuit 2 is constituted of an integration circuit, a current which is consumed in the interruption commanding circuit 2 is only a current for charging and discharging a capacitor of the integration circuit, and it does not occur that the power consumption the HALT mode increases.

Title: Cathode-ray tube for color display
Inventor: KOBAYASHI HIROO
IPC: H01J29/18
Filed: 1981-07-17
Abstract: PURPOSE:To obtain a cathode-ray tube which is used for a easily seen color display with a bright picture surface, without sacrificing the contrast effect, by forming the fluorescent screen of each emission color by mixing phosphors with different emission colors. CONSTITUTION:When a green color is desired to have a tint of yellow, use of a yellowish green phosphor doesn't work since the yellow color is cut by the absorption band of glass. However, if a fluorescent screen is prepared by mixing a red emitting phosphor into a green emitting phosphor, the effect of a face plate containing Nd2O3 and the like and having a wavelength selectivity is fully exhibited, and a desired color tone is obtained without sacrificing the contrast. As for a blue color, since a highly pure blue used for a display indicating letters and figures is difficult to be seen and tires the people who are looking at the display, a blue emitting phosphor is mixed with appropriate amounts of a green and a red phosphor so as to enable the blue color to have a whitish color tone and to obtain a display which can be much more easily seen. In addition, if a small amount of a green emitting phosphor is mixed into a highly pure red emitting phosphor, the emission color can be made close to orange color while maintaining the improving effect of the contrast.
