IPC: C08G63/80
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To obtain a polyester resin suffering little bleeding of a plasticizer, having flexibility and suitable as, e.g. a packaging material by melting and reacting an aromatic polyester and an aliphatic polyester of a specified number- average molecular weight. SOLUTION: An aromatic polyester is produced by using an acid component, such as terephthalic, isophthalic or 2,6-naphthalenedicarboxylic acid, and a glycol component, such as ethylene glycol or propylene glycol. Separately, an aliphatic polyester with a number-average molecular weight of 10,000 to 100,000 is produced by, for example, the polycondensation of a polybasic acid, such as succinic or adipic acid, and a glycol component, or the ring-opening polymerization of a cyclic acid anhydride composed mainly of succinic anhydride and a cyclic ether composed mainly of ethylene oxide. The aromatic polyester and the aliphatic polyester are then melted and reacted to produce a flexibilized polyester resin. This resin is free from the deterioration of physical properties due to the randomization reaction caused by heating when molded.

Title: Radiation image detector
Inventor: TAKAHASHI TETSUHIKO
IPC: H01L31/09
Filed: 1987-04-17
Abstract: PURPOSE:To obtain a high quality of X-ray image even in a low-dose photography, by amplifying a weak signal attributed to X rays before being mixed with a noise to obtain an electric signal with a high S/N ratio. CONSTITUTION:First, a switch 11 is turned to the position of a power source 9 and light is radiated with a voltage applied between transparent electrodes 2 and 2 to induce electrons and positive holes in the surface of an insulation layer 8. Then, the switch 11 is turned to the position of a power source 10, a voltage between the electrodes 2 and 2 is maintained at a high potential and under such a condition, X rays are radiated. The X rays are converted into light with a phosphor 1 and then absorbed by a photoconductor layer 3 to form an electron-hole pair. The electrons and holes multiply being swept in the opposite direction to one another by a strong electric field produced with the electrode 2. Finally, the holes reach the surface of the insulation layer 8 and an electric charge induced with the power source 9 decreases by recoupling. Then, image information is formed as charge pattern multiplied on the surface of the insulation layer 8. This enables the increasing of image information accumulated on the photoconductor layer 3 before being mixed with a noise, thereby producing an image with a higher S/N ratio.

When the end 7a of the arm 7 makes contact with the pin 3 press-fitted to the hole 2 of the shaft 1, it prevents the shaft 1 from rotating. When the shaft 1 rotates counterclockwise, the clutch 4 is wound on the shaft 1 to rotate together to energize the arm 5 so that the arm 7 approaches the shaft 1. As a result, the end 7a of the arm 7 makes contact with the pin 3 to restrict the rotation of the shaft 1.

Abstract: PURPOSE:To make display extremely easy to grasp by superimposing a characters for showing a reception channel and a character for showing a reception broadcasting mode on a picture on a picture display element as pictures. CONSTITUTION:A display switching circuit 25 selects a character to be displayed in a display period on the basis of outputs F and H of timers 26 and 27 and an output I from a recall switch 34.

The readout timing of a readout timing pulse generating circuit 33 for a character generator 23 and the kind of a character to be read are changed to control the character generator 23. The display signal P of a character generated by this character generator 23 is applied to the video output circuit 7 of a television receiver 1 through a color switching circuit 30 to display the character on the screen of the cathode ray tube 10.

IPC: H04M3/02
Filed: 1982-06-01
Abstract: PURPOSE:To reduce the relay contact capacity at the interface of an independent telephone set, and to perform size reduction, and to reduce noise, by performing switching between a current supplying circuit for an independent telephone set channel and a ringing generator during the period in which a ringing is retaining zero-potential. CONSTITUTION:When the independent telephone set connected to a chip T and a ring R receives a ring-on signal from a telephone switchboard body at an RING input 114 in an on-hook state, a relay control circuit 102 detects the moment when a ring voltage falls to zero, and then turns on a relay 106(t) seconds later to place a relay contact 105 at a side (b). When a ring call is turned off, the switching is performed similarly (t) seconds after the ring voltage falls to zero. A constant voltage diode 108 prevents a high voltage from being developed between the T-R and a diode 109 stops the application of the ring voltage in off period. If a high voltage is generated at the side R, it is clamped by a diode 110.

Title: Hydraulic shock absorber for motorcycle
Inventor: HANAWA NOBUMICHI
IPC: B62K25/08
Filed: 1986-04-23
Abstract: PURPOSE:To prevent cylinder bottom hitting of a piston by clamping a damping valve of a working fluid passage between a spring having a small spring constant, which is supported by a piston member and a spring having a large spring constant, which is supported by a cylinder member. CONSTITUTION:When a piston 3 is slid to pressure side, working fluid in an oil chamber 5 of an outer tube 1 flows into an oil chamber 6, and oil which can not be accommodated therein passes a damping valve 9 disposed in an oil passage 7 to flow into an oil sump chamber 8 while it generates damping force. Simultaneously suspension springs A, B clamping the damping valve 9 are sagged. At this time, the spring A having a small spring constant is sagged largely, so that the damping valve 9 is deflected to the oil sump chamber 8 side to decrease damping force. When the contraction of the spring A reaches its limit, the relative deflection of the damping valve 9 is stopped, and only the spring B having a large spring constant is sagged and displaced with the piston 3 to the pressure side to largely increase damping force. Thus, of the piston can be prevented to attain good grounding ability and operability.
