Title: Radiation detector
Inventor: NAKAMURA SHIGERU
IPC: G01T1/20
Filed: 1989-06-08
Abstract: PURPOSE:To prevent crosstalk as caused by leakage of light to a photo detector at an adjacent channel by providing a second reflecting member at least one end of scintillator elements in a direction orthogonal to the way of arranging the elements side by side along the collateral direction thereof. CONSTITUTION:Spacers 2 and scintillator elements 1 are arranged alternately side by side and a spacer 9 as second reflecting member is inserted into a groove 20 provided at an end thereof in a direction of slicing the elements to join using an adhesive. The scintillator elements 3 thus inserted and joined are bonded together with a transparent adhesive on a printed wiring board 7 on which a multi-channel type photo diode 5 is mounted in such a manner that channels match the elements 1. Then, incident X rays are inputted into the elements 1 through a collimator 11 in a range of an end face (b) from an end face (a) of a slit 10 for shielding scattered rays. As the spacer 9 is arranged on an outer surface from the extension of an X-ray incident surface of the slit 10, out of light emitted with the elements 1, light in a slicing direction is absorbed by the spacer 9. This eliminates leakage of light between the elements 1 thereby allowing the prevention of crosstalk.

Title: Pneumatic tire
Inventor: SHIYOUYAMA NORINOBU
IPC: B60C9/20
Filed: 1986-06-23
Abstract: PURPOSE:To improve the steering stability and durability of a pneumatic tire for car by specifying relational equations between the filament diameter of metal cords constituting a belt ply, the number of filaments, and the total number of buried metal cords. CONSTITUTION:Each of metal cords 17 constituting a belt ply 16 is made by twisting multiple filaments 19. In this case, the diameter Ri of the filament 19, the number (m) of filaments constituting one cord 17, and the total number (n) of cords 17 buried in a belt layer 14 are set so as to satisfy Equation I and Equation II. Acoording to this constitution, the metal cords are made easy to be bent, and even if the metal cords tend to fall due to drift, they are pulled back by the inter-layer rubber and deformed. Accordingly, the inter-layer shearing strain is mitigated and separation is suppressed, thus the steering stability and durability of a tire can be improved.

Title: Endless ink ribbon
Inventor: FUDATSUJI TOSHIHARU
IPC: B41J31/00
Filed: 1980-10-20
Abstract: PURPOSE: To improve the slidability of an endless ink ribbon and to broaden its surface area to be used, by forming an ink-unapplied zone at the side end, sliding on the lower surface of an ink-ribbon-receiving vessel of the widthwise side part of the ribbon.  
     CONSTITUTION: When an endless ink ribbon 1 is put into an ink ribbon-receiving vessel and received in a folded state, an ink-unapplied zone 16 having a width of 0.5W1.5mm or so is formed at the side end 15b, being in contact with the lower surface of the ink robbon-receiving vessel, of the ink ribbon 1. At ink-applied zone 17 is formed at the remainder part of the ink ribbon. As a result, the possibility that the lower surface of the ink ribbon-receiving vessel is wetted with ink is lowered. Consequently, the ink ribbon can be widened without reducing its slidability.

Title: Deceleration sensing type damping oil pressure control unit
Inventor: NOGAMI SATOYUKI
IPC: B60T11/34
Filed: 1978-11-28
Abstract: PURPOSE: To control adequately the motion of a differential piston with a spring to allow the distribution characteristic of a damping oil pressure applied to the front and the rear wheel cylinders to make close to an ideal characteristic.  
     CONSTITUTION: Working a pedal 19 allows the cylinders 13, 15 to apply an oil pressure for damping. In this case, a small diameter piston 30 and a large diameter piston 31 are respectively pushed by oil pressure, both pistons being compressed to the side of the first oil chamber R 1 , allowing not to displace owing to smaller than the preliminary load of the first coil spring 51. When the oil pressure PM reaches P 1  and the deceleration acting on the inertial ball 41 reaches a certain valve, the ball 41 is seated on the valve seat 42 to close the cut-off valve 40. In this case, the compressed force becomes equal to the preliminary load for balancing the compressed force. While the oil pressure PM is built-up to allow the oil pressure of the oil chamber R 1  to become P 3 , the oil pressure of the oil chamber R 2  may not be increased, permitting not to change the oil pressure of the cylinder 15. Additionally, when PM is built-up, the pistons 30, 31 are displaced to the oil chamber R 2  against the spring 52, allowing the oil pressure P w  of the cylinder 15 to increase until the  piston 31 to have in contact with the inner wall 23b.
