Title: Vibration controller
Inventor: UENO KAZUYOSHI
IPC: G05D19/02
Filed: 1992-03-16
Abstract: PURPOSE:To perform vibration tests having a large target spectrum component in a low-frequency area even by with a vibration generator having a small rated displacement value. CONSTITUTION:An A/D converter 8 converts the vibration data of a specimen 4 into digital signals and a Fourier transformation means 10 calculates a response spectrum from the digital signals. A control and arithmetic means 12 calculates a drive spectrum by comparing the response spectrum with a target spectrum. An inverse Fourier transformation means 14 performs inverse Fourier transformation on the drive spectrum. In addition, a window operating means 16 makes the spectrum structure of a drive signal continuous and a D/A converter 18 converts the drive signal into an analog signal. A low-frequency output signal filtering means 19 removes unnecessary low-frequency output signals of 'coming-out signals' caused by the window operation of the means 16.

Inventor: TAKAHASHI AKIRA
IPC: F22D1/32
Filed: 1990-03-12
Abstract: PURPOSE:To prevent an over-shooting or an under-shooting of a water level and perform a stable water level control for a water supplying and heating pipe by a method wherein a drain water level controller is provided for calculating a degree of opening of a water level adjusting valve corresponding to an increased or decreased amount of flow rate in which a drain flow rate and a flow rate of extracted steam are added and a control over a degree of opening of the water level adjusting valve is corrected in advance on the basis of the calculated value. CONSTITUTION:In this type of drain water level controller, even if the flow rare of drain water from the first water supplying heater 1 flowing into the second water supplying heater 2 or the flow rate of extracted steam flowing into the second water supplying heater 2 is rapidly varied, a degree of opening of a water level adjusting valve 5 corresponding to an increased or decreased amount of the flow rate of drain or the flow rate of extracted steam into the second water supplying heater 2 is calculated by the drain water level controller 20, this is corrected with the calculated value prior to an output signal from a normal water level sensor 6, thereby opening or closing of the water level adjusting valve 5 is controlled and then a stable drain water level control can be carried out by preventing fluctuation of the drain water level within the second water supplying heater 2.

Filed: 1989-03-10
Abstract: PURPOSE:To attain high speed processing by using a detection section so as to detect succeeding linear encoding code and applying decoding processing to a succeeding 2-dimension successive encoding data with other decoding section while the 2-dimension successive encoding data after the linear encoding code is subject to decoding processing by one decoding section. CONSTITUTION:When a detection section 22 detects a linear encoding code MH among 2-dimension successive encoding data, the 2-dimension successive encoding data after the detected linear encoding code MH is decoded by decoding sections 14, 15. The detection section 22 detects the succeeding linear encoding code MH during that time, the 2 dimension successive encoding data is subject to decoding processing in parallel by other decoding sections 15, 14 from the detected linear encoding code MH. Thus, the 2-dimension successive encoding data such as MR encoding data is subject to decoding processing at a fast speed.

Title: Charged particle beam lithography equipment
Inventor: MATSUDA KOREHITO
IPC: H01L21/027
Filed: 1989-03-10
Abstract: PURPOSE:To prevent a displacement of a beam axis by a changeover operation of a beam diameter or to prevent a thermal strain of a beam diaphragm and to change over the beam diameter at high speed and with high accuracy by providing a variable beam-limiting diaphragm whose opening diameter is concentric and variable. CONSTITUTION:A variable beam-limiting diaphragm 7 is connected to a tip part 10A of an arm 10 protruding from a diaphragm-blade operation ring 9; the diaphragm-blade operation ring 9 is turned by a driving rotary sheet 11 which moves the arm 10; an opening diameter 7A is formed in the central part 12B by a plurality of diaphragm blades 12. Accordingly, the opening diameter 7A can be changed arbitrarily; a beam diameter and a beam current can be controlled. Since the opening diameter 7A can be changed in a concentric circle shape by using a beam axis X as its center, a displacement of the beam axis X can be neglected; in addition, since the opening diameter 7A is always irradiated with an electron beam 6, it is thermally stable and a change in the opening diameter 7A by a thermal strain can be made extremely small. Thereby, it is possible to suppress an influence by the displacement of the beam axis or by the thermal strain; a high-speed changeover operation can be realized; a high-speed and a high-accuracy lithographic operation can be achieved.

IPC: H01S5/026
Filed: 1983-04-05
Abstract: PURPOSE:To enhance the productivity by simplifying the process of forming an electrode by a method wherein a region including a photo guide layer provided with diffraction grating is put in a p-n-p-n structure. CONSTITUTION:This multilayer film structural substrate has a p type InP leakage blocking layer 11 introduced under the photo guide layer 10. By the introduction of the leakage blocking layer 11, the multilayer films is of p-n-p-n junction in conductivity constitution at the part of a terrace region on the left side of a stepwise difference 40, and only of p-n junction sandwiching an active layer 3 at the region on the right side. Therefore, when a forward directional bias whose positive is on the side of a cap layer 8 and negative is the side of the substrate 1 is impressed, the current is all injected to the active layer 3 on the right side of the stepwise different 40 in the state of normal operation at the voltage of the TURN-ON of the p-n-p-n junction (approx. 10V) or less, resulting in light emitting recombination with good efficiency. Besides, the process of forming the electrode can be largely simplified, since the p-side metallic electrode 32 can be formed by vapor-depositing Ti/Pt/Au over the entire surface of the cap layer 8 as the electrode material.
