Title: Error rate measuring system
Inventor: MANABE TSUTOMU
IPC: H04L1/00
Filed: 1984-06-01
Abstract: PURPOSE:To simplify the system constitution by extracting each synchronizing pulse of plural channels and allowing majority decision of frame synchronizing pulses extracted in this way to detect an error pulse thereby counting the error pulse and measure the error rate. CONSTITUTION:A demodulation circuit 1 of the system demodulates a reception modulation signal and a data of channels CH1-CHn corresponding to the modulation system is inputted to a sampling circuit 2. Moreover, a clock CK is frequency-divided by a frequency-division circuit 4, adds the result to the circuit 2 as the frame synchronizing sampling signal, the data of the channels CH1-CHn is sampled and its sampling output is fed to a correlation circuit 3 and an error extracting circuit 5. The correlation of the channels CH1-CHn is obtained to control the frequency dividing ratio of the circuit 4 thereby maximizing the correlation value at each frame period. Then the extraction circuit 5 uses the majority decision of frame synchronizing pulses so as to extract the error pulse, the error count circuit 6 obtains the error rate to simplify the system constitution.

Title: Throwaway end mill
Inventor: MATSUMOTO KEIICHI
IPC: B23C5/10
Filed: 1989-04-28
Abstract: PURPOSE:To allow rear face machining for a (T) groove, even if small in height, in a throwaway end mill which is composed of a throwaway chip and a shank for fixing the chip by forming the throwaway chip into isosceles right triangle to install a cutting edge on the slope of the isosceles right triangle. CONSTITUTION:A throwaway end mill is made up with an isosceles-right-triangle throwaway chip 1, a shank 2 and a set screw 3, and the throwaway chip 1 has a cutting edge 1a installed on the slope portion of a isosceles right triangle. In case that the throwaway end mill is used to perform rear chamfering for a (T) groove 5a, the throwaway end mill held by a collet holder 6 can have a small edge height h1 because the throwaway chip is formed into isosceles right triangle. It is thus possible to perform chamfering even if the groove 5a has a small bottom height (H).

Title: Resin composition containing organic peroxide in high concentration
Inventor: KONDOU MAMORU
IPC: C08L23/00
Filed: 1981-07-16
Abstract: PURPOSE:To provide the titled composition capable of dispersing the organic peroxide homogeneously in a resin when charged together with resin pellets in an extruder, and stabilizing the rate of extrusion in extrusion molding of the resin, by adding an organic peroxide in high concentration to a resin containing specific amount of vinyl acetate. CONSTITUTION:100pts.wt. of a resin containing >=15wt% vinyl acetate (preferably an ethylene-vinyl acetate copolymer resin) is compounded with 10pts.wt. of an organic peroxide (preferably dicumyl peroxide). When the content of vinyl acetate in the above resin is less than 15wt%, the organic peroxide becomes liable to bleed to the surface of the pellets of the composition during the storage of the composition, and the homogeneous dispersion of the organic peroxide by the simultaneous charging to an extruder becomes difficult. An advantage of the process is elimination of the kneading process at a temperature above the melting point of resin pellet which is essential to the conventional method using a resin pellet and an organic peroxide.

Title: Linear scanning method and system for energizing optical fiber bundle electrically
Inventor: KENESU PII GUREESU
IPC: G02B6/25
Filed: 1993-05-13
Abstract: PURPOSE: To decrease energy per pulse (or cw equivalent) sent to a patient, and to reduce the size of energy source. CONSTITUTION: In a method and equipment to relatively move energy across an optical-fiber array 20, energy from a laser-and optical-system aggregate 70 is scanned across the array 20. A dielectric mirror 13 installed on the scanner 12 of a galvanometer is moved so that the consecutive pulses may irradiate different segments of the array 20. As a result, each fiber is given such radiation which has sufficient influence and reduces energy per pulse (or cw equivalent). The array 20 itself is moved rather than that energy is moved across the array 20. A possible method of this movement is to use a piezo-electronic layered product.

Title: Magnetic clutch
Inventor: FUSHIKI MASAAKI
IPC: F16H48/30
Filed: 1989-04-05
Abstract: PURPOSE:To transmit a large clamping force to a multiple disk (friction) clutch speedily by installing an electromagnet supporting a yoke free of movement and a clamping member clamping the friction clutch as well as an adjusting means, moving the yoke, and adjusting an air gap between the clamping member and the electromagnet. CONSTITUTION:A differential case 17 is rotated by rotation and drive of an engine and a rear axle 11 is rotated through a pinion shaft 29, a pinion gear 33 and a side gear 37. A pair of clutch plate sets consisting of clutch plates 43, 45 are installed between this side gear 37 and the differential case 17, forming a multiple disk clutch 47. A yoke 59 of an electromagnet 57 is shiftably supported in the axial direction and rotated by a motor 47 via a worm 71 as in an arrow, forming an adjusting means. A clamping member 77 consists of a sleeve 79 and a flange 81. Since an air gap between an electromagnet and a clamping means is kept in an optimum value by this adjusting means, a large clamping force is speedily transmitted to a multiple disk (friction) clutch. Therefore the electromagnet is also enough to be small in size.

Filed: 1990-04-26
Abstract: PURPOSE:To prevent twining of mowed weeds in a mower by attaching supporting units vertically nipping a band cutter to a square part where the lower cutting side of the band cutter starts winding round a driving pulley. CONSTITUTION:A band cutter 14 is moved forwards while cutting weeds by the cutter edge on the front side following rotation. The mowed weeds are conveyed sideways by the band cutter 14 in accordance with the rotation and then discharged backwards through a gap between both the pulleys 11 and 13. During the operation, the mowed weeds placed on the upper surface of the band cutter 14 and conveyed to the direction of the driving pulley 11 are removed and discharged from the band cutter 14 backwards by supporting units 17 attached so as to sandwich both the upper and lower surfaces of the band cutter 14 at a point of time when the mowed weeds reach the neighborhood of the pulley 11. In this case, the mowed weeds on the upper surface can be prevented from forcibly pressing down the band cutter 14 and from entering into the gap between the band cutter and the upper supporting unit as the band cutter 14 is supported not only from the upper side but from the lower side in the neighborhood of the driving pulley 11.
