Title: Automatic system switching system
Inventor: YAMAMOTO YOSHIMASA
IPC: G06F11/30
Filed: 1986-01-07
Abstract: PURPOSE:To switch the system of a wide-range network at a high speed and with high reliability by transmitting signals periodically to a computer set at the side of a waiting host center from a supervisory unit set at the side of a working host center. CONSTITUTION:A CPU 2 serves as a working system which offers services to a network NW1 via a node processor NPC8. While a CPU 6 serves as a waiting system which offers services to the NW1 via a node processor NPC9 in place of the CPU 2 when a disaster occurs in an area A. Furthermore both CPU 5 and 3 serve as waiting systems which offers the services different from the CPU 2 to the NW1 and the services to the NW1 in place of the CPU 5 when a disaster occurs in an area B respectively. A supervisory unit 4 sends signals periodically to the CPU 6 and the CPU 6 offers services continuously to the NW1 in place of the CPU 2 in case the signals sent from the unit 4 are interrupted. In the same way, the signals are sent periodically to the CPU 3 from a supervisory unit 7 and the CPU 3 continues the services to the NW1 in place of the CPU 5 in case the signals sent to the CPU 3 are interrupted.

Abstract: PURPOSE:To reduce power consumption while maintaining the number of gradations by reducing a frequency of light emission of a line in the upper end and/or the lower end of a picture of every sub-field than the line in the center of a screen. CONSTITUTION:The display of 256 gradation is performed by dividing one frame into eight sub-fields and selecting light emission in the sub-field for pixels on every scanning line. Then, a position (timing when an erasure pulse is applied) of erasure is controlled so that the frequency of light emission (light emission time) is reduced for the scanning line (row) of the center of the screen as approaching the upper end (1 row) or the lower end (K row) of the screen. That is, respective scanning lines in the vicinity of the center of the screen of respective sub-fields are written by the application of a data pulse and a scanning pulse, and discharge light emission is started, and the discharge light emission is repeated by a maintaining pulse by the frequency of light emission according to the weighting, and the light emission is stopped by the application of the erasure pulse.

Abstract: PURPOSE:To obtain a resolving power having the given number of bits or over by moving an image pickup means converting an optical image to an electric signal to the optical image so as to use an inexpensive image pickup element with the less number of bits. CONSTITUTION:When an original 7 is lighted by a lighting light source 8 such as a fluorescent lamp, a picture recorded on the original 7 is formed on an image pickup element 5 by a lens system 9.

Filed: 1982-01-08
Abstract: PURPOSE:To judge the possiblity of continuous photographing, by detecting a value of a fixed physical quantity at the time of actual light emission as a variable related to the amount of light emission and comparing the maximum value of the fixed physical quantity to the maximum amount of light emission at which the charging of the main capacitor can follow continuous photographing. CONSTITUTION:At the time when the charge voltage of a main capacitor 7 becomes so high as to let a flash discharge tube 10 emit the light, a neon tube for displaying the completion of charging lights, a thyristor 9 is turned on, a discharge current flows to the primary side winding of a transformer 20, and the flash dischage tube 10 starts the light emission at the high voltage induced at the secondary side. When reflected lights from an object come into a photoreceptor element 38, a capacitor 39 is charged with a photocurrent corresponding to the reflected light, and this charging voltage reaches the voltage at a point P6 which is obtained by dividing the constant voltage of a diode 30, the output of a comparator 37 is inverted into a high level and a thyristor is turned off, and then, the light emission of the discharge tube 10 is stopped. When the time at which the output of the comparator 36 is at a high level is represented as TM (maximum flashing time) and the flashing time is represented as T, continuous photographing  is possible when TM>T.

Title: Camshaft arrangement and manufacture thereof
Inventor: PANAJIOTEISU ADAMISU
IPC: B23P15/00
Filed: 1991-01-11
Abstract: PURPOSE: To simply manufacture a camshaft while securing characteristics favorable to the effects of a valve head curve by providing the other component of swivel joints to the outside of a hollow cylinder and providing a ring which connects the both and partitions a recess in the end side in a range between a cam and the end side of the hollow cylinder. CONSTITUTION: The connection permitting the relative turning in such an angled range as being formed by extending a recess 7 in the circumferential direction is present between a cam 3 and a hollow cylinder 2. If an arrow is supposed in the rotation direction of a shaft 1, swivel joins 7, 8 entrain the cam 3 in their rotation so that an affixed upper valve is deviated to an opening position by the cam 4 via tappet. As soon as the head of the cam 4 leaves from the tappet, the force of a valve closing spring allows the cam 4 to turn freely from an entrainment member 2 so that the both side edges of the recess 7 and the entrainment part 8 including the interval between them are in contact together. The relative turning of the cam 3 is attenuated by a throttle hole 9.
