Title: Device for preventing moving body from floating up
Inventor: TAKAGI JIYUN
IPC: F16C29/02
Filed: 1981-04-15
Abstract: PURPOSE:To simplify the structure of an optical carriage or the like, facilitate its assembly, reduce the friction on its sliding parts and facilitate its adjustment, by providing a magnet pad as a part of the body of the optical carriage or the like, which slides on an iron rail. CONSTITUTION:Magnet pads B are provided on both the ends of the carriage body 1 of a moving unit A so that attractive force is caused between each pad and a rail 6. For that reason, the magnets B are attracted on the rails 6 when the moving unit A moves on the rails. Therefore, the moving unit A is kept from floating up. Since the sliding surfaces of the unit A are in contact with only the tops of the rails 6, the friction is reduced. Since conventional leaf springs or the like are not needed, the constitution is simplified and the assembly and adjustment are facilitated.

IPC: H04L1/16
Filed: 1986-03-12
Abstract: PURPOSE:To reduce a system overhead, and to increase a line activity efficiency, by overlapping a reception confirming number to an information transfer frame judged as the one having a normal transmission order number, on a transmitting information transfer frame from its own station. CONSTITUTION:It is assumed that a transmission order number is set as S1, a reception state variable as R, a reception window value as W, and the modulo of the transmission order number as M. An affirmative response sending managing means 3 stores the value of the present reception state variable R + reception window value W. When an affirmative response frame sending request means 4 is in a state that it is registered in a timer queuing, and additionally, a new normal information transfer frame is received, it is decided whether the present reception state variable R is equal to the R+W stored previously. And when they are equal, an affirmative response sending request indicator is turned on, and after that, a control is handed to a transmission frame managing and forming means 7. The transmission frame managing and forming means 7 forms an actual frame according to a bit of indicated frame forming information.

Title: Gas type angular velocity detector
Inventor: IKEGAMI MASAYUKI
IPC: G01C21/28
Filed: 1990-03-07
Abstract: PURPOSE:To accurately detect an angular velocity by setting plural tables which differ in characteristics according to the initial temperature at the rising of internal temperature, selecting the table whose characteristics are closest to the detected temperature of a temperature sensor, and performing offset correction. CONSTITUTION:When a temperature detection signal is sent from the temperature sensor, the initial temperature is held in a latch 1 and a table selecting circuit 2 outputs a table selection command to switch circuits 31 and 32 according to the held initial temperature. Then the circuits 31 and 32 switches properly according to the table selection command and circuit connections are so made as to select specific tables 4x (x=1, 2...). Then a specific offset value is read out of the selected table 4x according to the temperature detection signal and an offset correcting circuit 5 correct the offset of an angular velocity signal by using the read offset value. Thus, the angular velocity operating on a detector main body can accurately be detected from right after the rising of the internal temperature.

Title: Carrier bed moving mechanism in electric machining device
Inventor: YOSHIOKA SUMIO
IPC: B23Q1/01
Filed: 1984-03-26
Abstract: PURPOSE:To prevent a stationary bed from deforming due to a shift of a loading point due to movement of a carrier base, to aim at enhancing the manufacturing accuracy, by arranging three rolls on the stationary bed in a zig-zagging pattern, and as well by arranging, on a movable saddle, three guide rails corresponding to the rolls. CONSTITUTION:Three saddle guide rails 3 for guiding the movement of a saddle 4 which is a carrier base, are secured to the lower section of the saddle 4 in a zig-zagging pattern, and as well three rolls 9 for allowing the saddle 4 to be movable are secured in a bed 1 beneath the three rails 3, respectively. Accordingly, the load of the saddle 4 is supported at three points by the rolls so that the burden is made uniform on the bed 1, and therefore, deformation of the bed 1 by means of the three rolls 9 may be made uniform. Further, since the rolls 9 are secured to the bed 1, the centralized load against the bed 1 is never varied by the movement of the saddle 4 so that the deformation of the bed may be always maintained constant. Therefore, a bed deformation due to the shift of the loading point caused by the movement of the saddle 4, etc. may be neglected for the relative displacement between a machining head 8 and a workpiece 7, thereby the accuracy of machining may be maintained.

Filed: 1982-04-05
Abstract: PURPOSE:To improve the characteristics of combustion in the case that fuel having a high ignition temeperature and a low burning rate is burnt in the condition of existence of a large amount of residual gas, by increasing the concentration of oxygen in intake air. CONSTITUTION:In a two-cycle engine in which combustion is difficult due to the condition of exsistence of a large amount of residual gas and fuel, e.g. natrual gas having methane as a main component is used, the characteristic of combustion is improved by increasing the concentration of oxygen in intake air to a value than that of normal air. That is, the component ratio of inert gas (nitrogen) which participates in combustion is reduced by increasing the concentration of oxygen in intake air so that the temperature of combustion is raised for promoting the reaction of burning. In order to increase the concentration of oxygen in intake air an oxygen having a high concentration is added from an oxygen adding port 6 into the intermediate section of an intake air system 2 through 5 in an engine body.
