Patent JP-H0850853-A (JP)
Title: Manufacture of electron emission element
Inventor: TANTANI YASUSHI
IPC: H01J9/02
Filed: 1994-08-04
Abstract: PURPOSE:To form a homogeneous cold cathode on a substrate by etching. CONSTITUTION:A plurality of divided metallic layers 35 (aluminum) are made on a substrate. Each divided metallic layer 35 is isolated by a groove G. The groove G has a width enough for functioning as a passage for etchant. Resist layers 32 having circular patterns about 5mum in diameter are made at pitches of 10mum vertically and horizontally. The whole of the substrate is soaked in etchant to perform wet etching. The divided metallic layer 35 consisting of aluminum is removed by etching, but only the section right below each resist layer 32 remains as a conical cold cathode. Since the groove G is made, etchant convects all over the substrate, and roughly homogeneous etching is performed as a whole.

Title: Valve clearance adjusting device of internal-combustion engine having valve action changeover device
Inventor: KATOU MANABU
IPC: F01L13/00
Filed: 1983-10-31
Abstract: PURPOSE:To prevent the movement of the contact surface on the top side of the valve stem so as to reduce partial wear and to facilitate adjustment of the clearance. CONSTITUTION:A rocker arm 42 is constructed so that it is capable of movement along the axis of a rocker shaft 41. Since the rocker arm 42 is selectively brought in contact with one of the plural cams having different shapes, the valve action characteristics are changed. A cylindrical roller member 44 having a larger width than the axial moving distance is mounted at the end on the valve side of the rocker arm 42 eccentrically, so that the rotary position can be adjustd, and it is brought in contact with the valve stem 43a. Since the curvature of the contact surface of the roller member with the valve stem 43a can be made large, the movement of the contact surface on the top side of the valve stem due to the movement of the rocker arm 42 is restrained and partial wear of the surface is reduced. Also, the adjustment of the rotary position of the roller member 44 facilitates adjustment of the clearance.

Title: Production of optical fiber preform
Inventor: IKUMA TOSHIROU
IPC: C03B37/014
Filed: 1983-10-31
Abstract: PURPOSE:To prevent the damage of an optical fiber preform at the weld part between the starting material and the drawing substrate, by changing the composition of the optical fiber only at a definite region near the starting end, and varying the expansion coefficient of the preform gradually toward the end part. CONSTITUTION:At the initial stage of the deposition of the soot 6 on the starting substrate 1 in the production of an optical fiber preform, the soot 6 such as SiO2 is deposited without addition of a dopant. Thereafter, the addition of a dopant is started, and the rate of addition of the dopant is varied gradually to the ultimate target content to form the main part 8B of the preform. The buffering zone 9 having a thermal expansion coefficient varying continuously along the longitudinal direction and produced by the above process is not used as the optical fiber. On the other hand, a zone 8A having varying outer diameter is formed near the end of the preform 8, and the zone cannot be used as the optical fiber and is used as the thermal expansion coefficient buffering zone 9. The porous preform prepared by this process is sintered at a high temperature to collaspse the spaces between the soot particles and obtain a transparent preform.

The estimated disturbance torques at respective sampling ties are stored in a table TB as average values DB(0)-DB(j). A predetermined quantity is added to these average values to store the upper limit values DC(0)-DC(j) of a tolerance range in a table TC. In the mold protecting section at each mold closing time, an abnormal load signal is outputted when the estimated disturbance torque calculated at every sampling cycle exceeds the upper limit value of the tolerance range.  A set value for judging abnormal load is automatically set and a mold is accurately protected.
