Title: Brush device of dc motor
Inventor: MATSUYAMA TAIJI
IPC: H02K5/14
Filed: 1987-09-24
Abstract: PURPOSE:To reduce machine noises by forming a mounting base for a brush from as resin having Shore hardness D of 50-70 specified in ASTMD 2240. CONSTITUTION:A mounting base 13 is made of resin having a Shore hardness D of 50-70 specified in ASTMD 2240, a brush terminal 12 which is spot welded with a brush 11 is fitted forcingly to the mounting base 13, and the mounting base 13 is fixed to a brush holder 10 by a screw 14. The mounting base 13 made of elastomer resin is soft so that oscillation generating from the brush terminal 12 is absorbed, and the oscillation is not transferred to the brush holder 10. The more soft elastomer resin the mounting base uses, the more favorable to reduce the machine noises, but Shore hardness D more than 50 is required. Accordingly, the machine noises coming from sliding of the brush 11 with the rectifier is absorbed at the mounting base 13, and the machine noises transferred to the brush holder 10 can be greatly reduced.

Title: Automatic spectrum detecting and warning apparatus
Inventor: KATAYAMA TAKASHI
IPC: G01R23/16
Filed: 1988-09-28
Abstract: PURPOSE:To make it possible to detect spectrums automatically without using vision based on the result of frequency analysis of a time series signal (undersea acoustic signal and the like) by providing a smoothing part, a memory part, an adding part and a spectrum detecting part. CONSTITUTION:A time series signal undergoes analog/digital conversion. Thereafter, the signal is converted into the digital discrete line of the frequency spectrums in a high speed Fourier transformation part 1. A smoothing part 2 outputs the waveform of the signal into a memory part 3 by convolution operation or with a recursive digital filter and the like. The stored data are retrieved with a display part 4 and displayed on a CRT display device or a gram recorder. An adding part 5 retrieves only the data corresponding to a preset frequency band so as to add the data. A spectrum detecting part 6 judges whether the value is larger or smaller than a preset threshold value. A warning part 7 issues warning when the detecting part 6 detects the spectrum so as to call the attention of the operator of the apparatus.

Title: Vibration test machine
Inventor: KUSUSE TADASHI
IPC: G01M7/02
Filed: 1992-08-18
Abstract: PURPOSE:To impart a clean sinusoidal acceleration to a sample by performing feedback control through a hydraulic cylinder for absorbing impact interposed between a coupling of a driving hydraulic cylinder and a table thereby absorbing distortion of acceleration caused by frictional force of the cylinder, backlash of the coupling, or the like. CONSTITUTION:When a table 7 is vibrated through motion of a piston 3 in a driving cylinder 11, the driving force Fc functions on a filtering hydraulic cylinder 14 as an external force thus urging the cylinder 14 to shift from a neutral position. But since the opposite ports of the cylinder 14 are short- circuited through an orifice 18 to constitute a positional servo system, shift X from the neutral position decreases as the value Ka of gain 21 increases in the servo system. Consequently, spring constant Kf of the cylinder 14 can be controlled through control of the gain Ka. Distortion in the acceleration of the table 7 caused by backlash of the coupling or the like may exceeds three times of shaking frequency, but it causes no distortion in the acceleration of the table 7 so long as the distortion occurs in the lowering region of gain.

Title: Carriage assembling body
Inventor: OKADA SADAO
IPC: G11B7/085
Filed: 1986-10-13
Abstract: PURPOSE:To improve the adhesive strength of a drive coil to a coil bobbin and to prevent the drive coil from peeling off from the coil bobbin by forming the longer side part of the coil bobbin, to which a carriage is firmly stuck, in a large shape with the rectangular part oriented outside. CONSTITUTION:The cross section of the longer side part 21 of the coil bobbin 20 firmly fixing to the carriage 1 is trapezoidal, and the overall cross section of the coil bobbin 20 is octagonal. Hence the vector of the tension of the drive coil 10 is applied to the side of the coil bobbin 20, and therefore the drive coil 10 is firmly wound on the coil bobbin 20 even if the tension of the drive coil in the middle of winding is small. If force to separate the drive coil from the coil bobbin 20 is applied to the drive coil 10, the drive coil 10 is hardly isolated from the coil bobbin 20 because of the long straight line of the longer side part 21.

Abstract: PURPOSE: To correct the azimuth error of a terrestrial magnetism sensor mounted on a car, being run, without turning the car once by suspensing its running operation regarding a method and an apparatus which are used to correct the azimuth error of the terrestrial magnetism sensor used in a self-contained navigation system. CONSTITUTION: Outputs of a terrestrial magnetism sensor are stored sequentially in a RAM (Step 1001). When a distance R' from a criterion point on a two-dimensional plane differs from a criterion distance R (Step 1004), it is judged that a magnetization state has been changed, data on three points is taken out from data stored in the RAM (Step 1008), and coordinates of one point which is situated in the distance R are taken out from it so as to be used as a correction value (Step 1010).

IPC: H04N5/225
Filed: 1985-10-30
Abstract: PURPOSE:To easily obtain the best focusing state by forming an edge signal as a flicker signal visually emphasized and displaying the signal on a view finder or the like while the profile in a finder image is flickered. CONSTITUTION:An original video signal is led to a profile or high frequency component extraction circuit 1, where a so-called edge component is extracted in a form of a profile signal or a high frequency component. The extracted edge signal is added intermittently timewise only at the focus adjusting in the frequency of 10-50Hz by an intermittent processing circuit 2. The intermittent edge signal subjected to an intermitting processing is fed to a synthesizing circuit 3, where the signal is synthesized into an original video signal and fed to a view finder 4, from which the finder video with emphasized profile is displayed. Thus, the excellent focusing is attained by matching the focus to the profile of the video image displayed most remarkably by the flicker intermittent edge signal.

Title: Speed change method used in coasting of vehicle
Inventor: SUMIYA KOJI
IPC: F16H63/40
Filed: 1985-10-29
Abstract: PURPOSE:To prevent waste in fuel consumption by automatically performing the idle running of an engine under its coasting condition where dry engine braking is unnecessary. CONSTITUTION:The requirements for using no engine braking is preset. A controller determines whether or not the current running of a vehicle satisfies said preset requirements. If the requirements are satisfied, a 3-4 shift solenoid 8 and B-O control solenoid 6 are turned on to cut off a power transmission line so that an engine is kept in the idling state regardless of vehicle speed. Hence the engine braking may not be employed more than needed so that wasteful fuel consumption can be prevented.

Title: Antivibration support
Inventor: TAKEHARA SHIN
IPC: F16F13/00
Filed: 1984-11-16
Abstract: PURPOSE:To reduce a vibration transmitting force by forming both wall portions of a fluid chamber of a vibration system constituted from an elastic body provided with a mass member to set a resonance point at will. CONSTITUTION:Pulsating pressure having phase opposite to that of pulsating pressure applied to a fluid chamber 29 in a support elastic body 21 is applied to a fluid chamber 29 by a vibration system 24 at the car body side to lower the spring constant and reduce the vibration transmitting force. Further, in frequency range higher than resonance point f2, as the frequency exceeds the resonance point f2, the direction of displacement of a mass body 26 is deflected from the exciting direction so that the mass body 26 moves to increase liquid pressure in the liquid chamber 29. Thus, when the resonance point of the vibration system 24 at the car body side is set to low frequency range in which engine shake takes place, the transmitted vibration can be reduced in said range.
