Title: Method of bending plastic cylinder
Inventor: MATSUMURA KEIZO
IPC: B29C53/08
Filed: 1984-08-03
Abstract: PURPOSE:To make round the cross section of each part of a bent plastic cylinder, by softening a plastic cylinder, sandwiching the cylinder between two planar plates with the space between them being equal to the outer diameter of the plastic cylinder, and bending the cylinder. CONSTITUTION:A plastic cylinder is heated to or over its softening point and while it is still soft, it is placed between planar parallel plates 10, and the plates 10 are pressed so that the distance between the plates 10 reaches the outer diameter 30 of the cylinder while it is bent to a desired degree. Thereafter, the temperature of the cylinder is allowed to lower below the softening point so that it is set. A bending mold 11 has a thickness 31 equal to the outer diameter of the plastic cylinder 30 and a radius equal to the desired radius of the arcuate of the intended bent cylinder. The softened plastic cylinder is bent along the beind mold 11. The cross section of every part of the bent plastic cylinder becombes round.

Title: Demodulation synchronization deciding circuit
Inventor: IWASAKI GENYA
IPC: H04L27/18
Filed: 1989-06-28
Abstract: PURPOSE:To execute the decision of synchronization only by a demodulated signal by calculating the phase angle of the demodulated signal from a signal for which a PSK input signal is orthogonally demodulated, counting the phase angle to the first counter when the phase angle is in a prescribed range, counting it to the second counter when it is out of the prescribed range and comparing the count values of the first and second counters. CONSTITUTION:An angle theta=tan<-1>(Q/P) on the phase surfaces of input orthogonal demodulated signals P and Q is calculated by a phase angle measuring circuit 101 and the value of the angle theta is compared with a prescribed value by a comparator circuit 102. When the value of the angle theta is in the determined range, a pulse is outputted to a counter 103 and when the value is out of the range, the pulse is outputted to a counter 104. The count values of the counters 103 and 104 are compared by a deciding circuit 105 and when significant difference is recognized between the both counters, it is decided that the demodulated signals are synchronous. Then, a decided result is outputted to an external part. When the significant difference is not recognized, it is decided that the signals are asynchronous. Then, the decided result is outputted to the external part.

Title: Braking device for hydraulic motor
Inventor: YASUI MASARU
IPC: F16D55/40
Filed: 1984-08-03
Abstract: PURPOSE:To keep off a shock due to too much effectiveness in a brake, by making an extent of braking force commensurate to a speed variation so as to act on in time of deceleration in a running motor. CONSTITUTION:When a feeding quantity from a hydraulic pump P to a running motor M is throttled by a directional control valve V, additional rotational frequency of the running motor M drops to some extent. At this time, with inertial force acting on the running motor M, pressure in a feed-discharge circuit 1a drops whereby pressure in both feed-discharge circuits 1a and 1b becomes identical with each other so that a selector valve K is selected to a neutral position, thus pressure oil in a pressure oil chamber UA is discharged to a tank T and braking force gets operating. On the other hand, after rotational frequency of the running motor M has dropped, drive of the running motor M by pressure oil out of the pump P is reopened, and the selector valve K is selected to a selecting position K3 so that braking force of braking devices B and B is released.

Filed: 1981-10-16
Abstract: PURPOSE:A preservative to added water, raising storing effect on flowers arranged in a vase, comprising a main agent obtained by blending aluminum hydroxide, alumium oxide or its mixture with a water-insoluble salt of calcium in a specific ratio or by calcining them. CONSTITUTION:A preservative for cut flowers comprising a main agent obtained by blending aluminum hydroxide, aluminum oxide or its mixture with a water- insoluble salt of calcium (e.g., calcium sulfate, calcium phosphate, etc.) in a molar ratio of (3:1)-(1:3), especially 1:1, or by calcining them at 70-500 deg.C. The use of another antiseptic[e.g., salicylic acid or an aninonic surface active agent (e.g., higher alcohol, etc.) together with the preservative improves further the storing effect. The addition of the preservative to water can store flowers for 15 days, which will wither in 2-3 days in water only. In the case of large- sized chrysanthemum, although flowers withered, roots were produced from stalks, leaves did not withered, side buds were out, and they were not dead after 90 days were over.
