Title: Device and method for charged particle beam exposure
Inventor: YAMADA AKIO
IPC: H01J37/304
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To surely detect local recessing and projecting sections formed on the surface of a sample to be exposed and, in its turn, to correct the surface of the sample with accuracy, by measuring the height distribution on the surface of the sample in a prescribed extent at a prescribed density or higher while the sample is loaded in a device. SOLUTION: The surface of a wafer W in a fixed small extent is irradiated with the light M from a light beam emitter 61 while the wafer W is set up on a stage 33, and the height variation of the surface of the wafer W in the small extent is measured by detecting reflected Light rays from the extent by means of a two-dimensional photodetector 62. When local recessing and projecting sections, etc., are generated on the surface of the wafer W, the detected pattern of the photodetector 2 is deviated from the position of a proper regular pattern. A height measuring and processing section 63 identifies the irradiating position of each light beam by processing the output signal of the photodetector 6, and calculates the height distribution on the surface of the wafer W from the amount of the positional deviation.

Title: Tape running control unit
Inventor: WADA TADAHIRO
IPC: G11B15/46
Filed: 1978-12-23
Abstract: PURPOSE: To ensure the high-accuracy control for the tape running by providing the means which generates the signals for the tape speed and the arm angle to a pair of tension arms, fixing one of the tension arms and then varying the velocity of the reel at the sending side via the velocity signal of the fixed arm.  
     CONSTITUTION: In case tape 10 is shifted toward the arrow mark, brake B is driven always to fix tension arm 3B. Then motors 2A and 2B are driven to turn reels 1A and 1B toward the arrow in the fixed speed. Thus roller 4B provided to arm 3B is turned to deliver the pulse corresponding to the speed from tachometer 5B. At the same time, the tensile force is applied to arm 3A in the direction of arrow B, and thus arm 3A is shifted to the fixed position in accordance with the tension of the tape. The voltage according to the rocking angle is delivered to potentiometer 7A from potentiometers 8A and 8B installed to arms 3A and 3B. Thus tape 10 is taken up to reel 1A, accordingly lowering the sending speed through reel 1B. In such way, the tape running can be controlled in a high accuracy without using the capstan roller.

Title: Method and device for aeration of sewage having open channel surface
Inventor: KUDOU SHINYA
IPC: C02F7/00
Filed: 1981-10-09
Abstract: PURPOSE:To utilize the energy for introduction of air as buoyancy and to improve the efficiency of aeration in a sewage treating tank or the like by introducing a prescribed quantity of air into water at a right angle to the water surface and releasing and floating the same at one time when the air arrives at a desired depth. CONSTITUTION:If the depth of water is assumed to be 5m, air begins to come out in the position (a) and the ejection ends in the position (b). In actuality, a group of the air ascends and enters the inside of a guiding funnel 13 where the air is finely segmented by a screen plate 14 and ascends in the form of fine foam. Since the ascending air group and the foam carry the water round the same upward as well, the water ascends like an arrow 15. On the other hand, the water in the water bottom intrudes into the basket 8 from which the air is discharged. As said water ascends like an arrow 16, the water in the bottom is pulled up and during the time when it moves from the position (c) to the position (d), the water is released into the air. Thus not only the water near the same is agitated effectively but also the effect of aeration is improved.

Title: Controller for constant current power source
Inventor: ISHIDA KOICHI
IPC: G05F1/10
Filed: 1990-06-20
Abstract: PURPOSE:To prevent resonance without requiring a damping resistance by multiplying an estimated value of a deviation signal and its linear and quadratic differential estimated values by different coefficients and adding multiplication results to obtain a compensation signal and setting three coefficients to optimum values led by automatic control logic. CONSTITUTION:A dynamic compensator 8 which outputs the compensation signal to compensate a control signal as the output signal of a current controller 70 is provided in parallel with this controller 70, and the compensation signal is fed back as the input signal. This compensator 8 consists of a state observer 81 which estimates an estimated value eA of a differential signal (e) as the input signal of the controller 70 and a computing element 82 which multiplies the value eA estimated by this observer 81 and its linear and quadratic differential estimated values by different coefficients and adds results to output the result as the compensation signal. Consequently, respective coefficients are set to proper values to cancel a quadratic formula related to S included in the denominator of the transfer function of a principal circuit. Thus, a no- damping control system free from resonance is obtained without providing the damping resistance in series to a capacitor.

Filed: 1982-09-17
Abstract: PURPOSE:To improve the coloration sensitivity and coloration safety more than the case of using carbazide alone and to determine free aliphatic acid, by using a mixture of diphenylcarbazone derivative corresponding to diphenylcarbazide derivative and diphenylcarbazide for a color former. CONSTITUTION:A solution mixed <=10% diphenylcarbazone derivative corresponding to diphenylcarbazide derivative with the diphenylcarbazide derivative, is used for the determination of free aliphatic acid in a living body sample (blood etc.). For example, di-p-methylphenylcarbazone is used for di-p-methyl- phenylcarbazide or diphenylthiocarbazone is used for diphenylthiocarbazide. In case of substituting benzene nucleous of the carbazide by halogen, the same halogen substituted carbazone is used. In this manner, sensitivity is higher than the case using the carbazide alone and the determination can be performed with good coloration stability.

Abstract: PURPOSE:To grow silicon epitaxially without using chlorine gas, by supplying Si2H6 and H2 to a reaction furnace while evacuating it so as to establish predetermined conditions within the reaction furnace. CONSTITUTION:A silicon substrate 12 is disposed in a reaction furnace 11. Si2H3 + H2 is supplied to the furnace while exhausted therefrom such that conditions of a pressure of 450-8130 Pa, a temperature of 640-920 deg.C and a growing gas flow rate of 10-10<3> cm/sec are established within the reaction furnace. According to such construction, there is no need for chlorine gas which would be used in conventional transverse epitaxial over-growing process and, therefore, damages to semiconductor devices can be avoided, Secondarily, by using a lower temperature than in the case of prior arts, an insulator is prevented from being undercut at its surface contacted with a substrate and, therefore, the insulator is hardly autodoped with an impurity doped in the substrate.
