Title: Transmission/reception system for satellite broadcast
Inventor: TAKIMOTO YUKIO
IPC: H04H20/00
Filed: 1987-01-28
Abstract: PURPOSE:To adjust the phase of a TV signal at a ground station, by detecting a phase difference between a reference frame synchronizing signal in a satellite and the frame synchronizing signal of a television video signal sent from a ground transmission station, and sending it to the ground transmission station. CONSTITUTION:A broadcasting satellite 100 detects the phase difference between an i-th number of TV signal and a reference frame signal at a switch matrix 4, and sends it to an i-th number of zone via an antenna 8i. The ground transmission station 90 of the i-th number of zone, after receiving it with a reception antenna 91, demodulates a phase difference detecting signal with a receiver 92, and impresses it on the transmitter 93 of the TV signal. Thus, the TV signal outputted from the transmitter 93 is delayed by a delay time designated by the phase difference signal and is outputted. In such a way, in a stationary state, the phases of all of the TV signals are synchronized with the reference frame synchronizing signal, and the phase of the TV signal can be kept as it is even when it is switched by the switch matrix 4.

Title: Variable displacement swash plate type hydraulic machine, and static hydraulic pressure transmission device
Inventor: AKASAKA YOSHIMICHI
IPC: F04B53/18
Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To reduce a pv-value at a slide part under high pressure and high rotation, and achieve high power density by disposing a piston to be conically inclined to a cylinder block in such a way that an axial center of a cylinder bore crosses with an axial center of a rotation shaft on the side of a swash plate. SOLUTION: A piston 7 is disposed to be conically inclined to a cylinder block 5 in such a way that an axial center of a cylinder bore 6 crosses with an axial center of a rotation shaft 2 on the side of a swash plate 11, so a pv-value (p: surface pressure, v: slide speed) between the cylinder block 5 and the piston 7, and between the swash plate 11 and a slipper 8 is reduced. In this constitution, force applied to a starting end part of the cylinder bore 6 by lateral partial force of the piston 7 can be reduced in accordance with an inclination angle of the piston 7. A piston stroke is thus increased to provide reduction effect of resultant force of the piston lateral partial force more clearly in accordance with inclination of the swash plate 11. Surface pressure at a slide part between the cylinder block 5 and the piston 7 can therefore be reduced.

Abstract: PURPOSE:To prolong the service life of a tool in performing ultra precision cutting on an electroless Ni-P plated layer particularly by reducing the radius of a cutting edge to the extent that the tipping resistance ability may not be spoiled by increasing the front top rake and side rake angles to the minus side by use of a natural or artificial diamond. CONSTITUTION:A natural or artificial diamond tool is made in such a way that the cutting edge radius R of which shall be 0.1 through 1mm in the vicinity of a rake face 110, and the side rake angle alpha and front top rake beta shall be -2 deg. through -15 deg. in relation to the plane to which a tool holder is attached respectively, and the back clearance angle gamma1 and side clearance angle gamma2 shall be -2 deg. to -15 deg. to the plane perpendicular to the plane to which the tool holder is attached. When the side rake angle alpha and front top rake beta is decreased gradually to the minus side in order to prevent the decline of the tipping resistance ability of the tool along with the decrease of the radius R of the cutting edge, the generation of tipping is decreased resulting in giving affection to tool life and the roughness of a finished surface opposite to each other. An electroless Ni-P plated layer has the longest life, if it is the one of which the component P is 8 through 15 weight %, and is applied with heat treatment at a temperature of 50 through 400 degree for 30 minutes through 3 hours, and the roughness of the finished surface Rmax can also be enhanced to the extent of Rmax <50nm that is the accuracy of the ultra precision finished surface.
