IPC: G02B6/04
Filed: 1991-01-31
Abstract: PURPOSE: To reduce defects and to reduce the production cost by making adjacent fibers of a tile element have relations between a top and a bottom to form many fiber assemblies. CONSTITUTION: Three 3-fiber triangular primitive elements 20 are collected to form a multi-fiber element 60 of the second stage. Tangential lines of outside edges of outer fibers of this multi-fiber element 60 are set to a regular triangle. Three multi-fiber elements 60 are collected to form a multi-fiber element 64 having a large number of degrees of freedom, and three multi-fiber elements 64 are collected to obtain a multi-fiber element 66 having a larger number of degrees of freedom. Thus, a product having an area larger than conventional is obtained, and further, it has less optical (for example, on an optical fiber face plate) and electronical (for example, on a micro channel plate) picture distortion. Especially, an element free from the inter-fiber transverse change between picture input and output ends is obtained.

Abstract: PURPOSE:To obtain a coating film with a uniform thickness, by forming a liquid sump space having a hermetically closed structure between a support and a rotary bar and providing coating solution introducing and discharge ports at the specific position in said space. CONSTITUTION:A coating solution introducing port 24 is positioned below the lowermost surface 29 of a rotary bar 20 and a coating solution discharge port 26 is positioned above the lowermost surface 29 of said rotary bar 20 while the diameter of the introducing port 24 is formed so as to be made larger than that of the discharge port 26. Therefore, pressure is applied to the coating solution introduced into the space 3 formed into a hermetically structure by a support and the rotary bar 20 and the space 30 is sufficiently filled with the coating solution and, therefore, the coating solution is uniformly adhered to the rotary bar 20 and the thickness of a coating film also becomes uniform. Because the liquid sump space 23 has the hermetically closed structure, the evaporation of the coating solution is reduced and the change in the viscosity of the coating solution is reduced even if the coating solution is used while recirculated.

Title: Method and equipment for sputtering
Inventor: KAGEYAMA SATOSHI
IPC: C23C14/54
Filed: 1995-01-27
Abstract: PURPOSE: To provide a method and equipment for sputtering using a collimator by which a collimating effect is not lost and the appearance of particles can be prevented. CONSTITUTION: With application of voltage of 200V between a collimator 8 and a semiconductor wafer 2, an electric field appears between them in the direction from the collimator 8 to the semiconductor wafer 2. Sputtered particles M which have obliquely passed through the collimator 8 are deflected in the normal direction of the semiconductor wafer 2 and then are deposited on the wafer. By using a collimator and an electric field together, an aspect ratio of the collimator can be made small when an interconnect material-made film is formed in a contact hole of a high aspect ratio. Therefore, a quantity of sputtered particles attaching to the collimator can be lessened and thereby the decline in a film forming speed can be reduced.

Title: Automatic focus adjuster for camera
Inventor: SHIMADA MASAKI
IPC: G03B3/00
Filed: 1986-01-21
Abstract: PURPOSE:To follow a considerable change of the light receiving quantity of an optical position detector in a short time even when the change is large, by changing the number of light emitting pulses logarithmically or in integral values close to the logarithimic values. CONSTITUTION:Upon receiving the output of a comparator 22, a microcomputer 23 gives a control signal, with which (V1+aV2) can become equal to a reference light quantity V0, to a light emission controlling circuit 10. In this case, the microcomputer 23 controls either the light emitting quantity by the current variation from the light emission controlling circuit 10 or the light emitting quantity by the fluctuation of the number of light emitting pulses. The number of the pulses is changed in such a way that the increasing rate of the pulse number can become constant irrespectively of the number of pulses, such as 4  8  16, etc., namely, the number of pulses is changed logarithmically. When the number of pulses is changed in such way, useless overlapped parts of ranges can be eliminated and the responding time of light quantity control can be shortened by the reduction in the number of stages.
