Title: Optical fiber multicore connecting method and connector
Inventor: SATAKE TOSHIAKI
IPC: G02B6/38
Filed: 1978-11-13
Abstract: PURPOSE:To reduce off-axial errors and enable connection of low losses to be readily accomplished by fixing the strands of optical fibers to multiple grooves and cutting the substrate with a cutting grindwheel parallel to the cutting grooves. CONSTITUTION:Marshalling grooves 15, axial aligning grooves 16, cutting grooves 17, protrusions 18 and adhesive agent extruding grooves 18 are worked on a silicon wafer, after which this is cut out to make a connecting substrate 14. While bare optical fibers 20 are being put into the grooves 15 from both ends in the axial direction of the substrate 14, they are butted to the protrusions 18, thence adhesive agents are filled in the spacings and are fixed by a retainer plate 22. The substrate 14 is then cut and ground with a cutting grindwheel 26 which has a width slightly wider than the spacing of the grooves 17 and being rotated by a shaft 17. The end face treatment by this cutting enables higher performance of the connecting work to be obtained.

Title: Defect inspection method and apparatus
Inventor: ROORENSU EICHI RIN
IPC: G01B11/24
Filed: 1988-06-08
Abstract: PURPOSE: To achieve a reliable defect inspection system that is used to manufacture a micro circuit by arranging a Fourier transform lens and an inverse Fourier transform lens along a light axis. CONSTITUTION: By positioning a wafer 12 within a front focal point surface 42 of a Fourier transform lens 34 and applying parallel laser beams 36 to the pattern surface, the surface Fourier conversion pattern is formed on a rear focal point surface 46 of the lens 34. A space filter 50 arranged on the surface 46 rejects light from the redundancy circuit pattern of a lit die 14 of the wafer 12 and at the same time passes light emitted from a defect. Light that is transmitted through the filter 50 or is reflected from it is subjected to inverse Fourier transformation by an inverse Fourier transform lens 54. Then, a filtered image is projected on a two-dimensional light inspection array 58, thus detecting the presence of light corresponding to a defect only in the die 14 on a light axis 48.  By mounting the wafer 12 on a two-dimensional parallel move 40 and moving the stage, all defects on the wafer surface with a number of redundancy circuit patterns can be inspected.

Title: Directional control valve
Inventor: SATO NOBUO
IPC: F16K11/04
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To keep a force constant at all times for pressing a valve to a valve seat, even upon the occurrence of a change in a plunger operating position and a plunger operation variable, by providing a compression spring between a plunger and the valve for pressing the valve to the valve seat with the action of the spring. SOLUTION: An operating compression spring 26 having a spring force larger than the force of a resetting compression spring 21 is laid between the end of the cylindrical part 22 of a plunger 4 and a valve 13b, thereby pressing a valve member C2 at constant spring pressure. Also, a cam surface has an operation cam surface for pressing the plunger 4 via a pressing lever mechanism 4 and actuating a directional control valve, as well as a resetting cam surface for releasing the plunger 4 from a pressed state and then keeping the plunger 4 in a reset state. The directional control valve is formed to cause the pressing force of the plunger 4 to act on the valve 13b via the compression spring 26.  According to this construction, the change of the operation variable of the plunger 4, if any, is absorbed by the compression spring 26, and the pressing force of the valve 13b to a valve seat 9b is thereby kept unchanged.

Title: Output amplifying circuit
Inventor: KANAI TAKASHI
IPC: H03F3/217
Filed: 1979-10-29
Abstract: PURPOSE:To improve the switching distortion, by setting an idling current so that an output transistor is not cut off. CONSTITUTION:If an output current (>0) is greater than an idling current, the voltage viewing a transistor 3a and a base from the output terminal is greater than the case when the output current is equal to zero. The potential at the middle of a resistance 13 follows the output voltage with the operation of a negative feedback circuit consisting of differential amplifiers 15, 20 Transistors 15a, 20a in the differential amplifier constitution are biased so that the current is less than that in the pair transistors in advance. When the current in the transistor 15a is increased and the gain is greater, the voltage across a resistor 12 is increased and the base potential of the transistor 3a is higher. Although the neutral potential of the resistance 13 is  not moved, the base potential of a transistor 5b is not almost changed, even if the current in a transistor 20a is decreased, to flow the idling current of a given value.
