IPC: H01L21/027
Filed: 1992-12-16
Abstract: PURPOSE:To propose a method for excluding influences of a proximity effect in electron beam exposure by means of combined use of photoexposure and to improve the precision of measuring a misalignment of a pattern formed in different layers. CONSTITUTION:After electron beam exposure in the step of lithography by electron beam exposure 4, a part where a proximity effect develops in the step of corrected exposure of proximity effect 5 is subjected to photoexposure before at least development.

Title: Alc circuit
Inventor: TANABE TAKESHI
IPC: H03G3/30
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce influence from a load and to enlarge a frequency band by providing a power divider for branching output into two, an amplifier for the amplification of one of output signals and the amplifier for feeding back and outputting the other output signal. SOLUTION: To the conventional constitution of a variable attenuator 20, a detector 50 and an integrator 60, the power divider 30 and the amplifiers 41 and 42 are added. The power divider 30 divides signal power by providing the impedance matching of input and output. For instance, in the case of using the three resistors of 16.6 Ω, the power divider of impedance 50 Ω and an attenuation amount 6dB is attained. The amplifiers 41 and 42 are provided with isolation characteristics for amplifying signals in a forward direction and attenuating the signals in an opposite direction. Since the isolation of feedback signals and reflection signals is enlarged, the influence from the load is reduced. Also, in the case of using the power divider for the branching of the signals, the frequency band is widened as well.

Abstract: PURPOSE:To make it possible to take out a sample without re-mixing it even under conditions of nongravitation to enable a continuous separation of sample by providing a sample container, a means for rotating the container, and a means for taking out a sample in the container during the rotation thereof. CONSTITUTION:At first, sample to be separated is fed from a feed container 25 to a sample chamber 6 of each sample container 2 through a pump 24, changeover valve 23, three-way valve 21, and connector 10. Feeding the sample can be performed during the rotation of each sample container 2, while the air in each air chamber 7 is exhausted through a changeover valve 31.

At this time, the valve 21 is changed over, while a pipe 20 is connected to a sampling container 22. As a result, a piston 5 moves to the side of a center of rotation C1 and the air in the container 2 is first exhausted and thereafter the sample separated is forced toward the center of rotation C1 so that the sample is taken into the container 22 through the valve 21.

IPC: H04N1/405
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To suppress an useless pulse from being mixed by applying the same bias to the plural reference pattern signals and applying bias calculation to digital image data in accordance with the level of the reference pattern signal thereby approximately equalizing voltage levels of respective reference pattern signals to each other. SOLUTION: In order to approximately equalize the levels of reference waves generated by reference wave generating circuit 28A-28C, a DC component generator 30 applies the same DC voltage to the reference waves and a bias from a controller 100 to a digital bias circuit 12 is previously finely adjusted. Besides, video data V2 obtained by applying the bias to video data V is converted into an analog signal by a digital/analog converter 14 and inputted to one of respective comparators 34A-34C. The three reference waves to be a reference pattern are generated by a video clock generated by an oscillator 18 and a clock by a flip-flop 22 with the doubled cycle. Thus, triangular waves having different cycle and nearly the same voltage 1 V are obtained.

Title: Tipped circular saw
Inventor: OSHIMA YOSHINOBU
IPC: B26D1/00
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive tipped circular saw which prevents its cutting edge tips from falling off from its tip seats for ensuring desired chip falling performance. SOLUTION: A tipped circular saw holds the circumferential length (b) of its tip seats 14 longer than the circumferential width (t) of its cutting edge tips 15 by 0.5 to 3mm. In cutting a hard plate member with the circular saw, that setting prevents the reaction of collision of larger chips of the hard plate member that have entered edge spaces 13 and moved to the cutting position with the hard plate member from acting on the cutting edge tips 15. The fixed cutting edge tips 15 is thus prevented from falling off from the tip seats 14 and breaking among other troubles. The bottoms 13a of the edge spaces 13 are situated below the lower ends of the cutting edge tips 15 to ensure a sufficient depth from the cutting edges to the edge space bottoms 13a, which never lowers the chip falling property of the circular saw.  The depth of the tip seats 14 are made shallower than that of the edge spaces 13 to shorten the cutting edge tips 15, which reduces the costs of the cutting edge tips 15 made of an expensive diamond-sintered body.
