Filed: 1985-08-07
Abstract: PURPOSE:To remarkably reduce the loss of steam at the inlet and to improve the heat efficiency of the titled separator by providing a steam distribution chamber communicating with the steam inlet and extending in the axial direction of the main drum between a couple of moisture separation elements. CONSTITUTION:The high-pressure turbine steam having high wetness flows into the main drum 1 from a cycle steam inlet seat 2 and the greater part of the steam flows into a steam distribution chamber 12 and branches right and left in the axial direction. As the steam flows in the axial direction, the steam flows into a chamber 18 under a partition plate 10 from a steam hole 19 provided to the partition plate 10. Then the steam branches right and left, flows along the circumferential direction of the main drum 1 and passes through a moisture separation element 5. Meanwhile, the greater part of water is removed and the steam flows out from a cycle steam seat 6. Since the cross-sectional area at the steam inlet part is sufficiently enlarged in this way, the inlet loss can be remarkably reduced.

Title: Method for measuring pattern of photoresist
Inventor: AIKAWA KATSUYASU
IPC: H01L21/027
Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To measure the pattern of a photoresist by means of an image and automate the measuring by irradiating the pattern of the photoresist with ultraviolet rays and image-picking up a fluorescence image generated thereby. SOLUTION: Ultraviolet rays are emitted from a light source 3. A dichroic mirror 6 is one type of interference filters and it has a feature that when it is placed at an angle of 45.degree. with respect to an optical axis, a short wave of which wavelength is shorter than a certain waveform is reflected thereby an long wave of which wavelength is longer than a certain waveform is passed therethrough. As a result, the ultraviolet rays are reflected and introduced to an objective lens 7, the fluorescence from the lens 7 is passed therethrough. The ultraviolet rays passing through the lens 7 is cast on a specimen 8 to be projected on a photoresist of the specimen 8, then fluorescence is generated. The fluorescence passes through the lens 7 and penetrates the mirror 6.  An absorption filter 9 limits a using wavelength range to be narrowed by overlapping a penetration wavelength range of the mirror 6 through which the fluorescence passing by being reflected by the specimen 8 with a penetration wavelength range of the absorption filter 9 so that a sharp image is obtained. An imaging device 10 images a fluorescence image of a pattern of the photoresist that is generated by the fluorescence.

Title: Output circuit
Inventor: YAMADA KAZUMI
IPC: H03K19/08
Filed: 1983-09-21
Abstract: PURPOSE:To obtain an output circuit outputting a transistor transistor logic circuit TTL level accurately with small size by using a few inverters and bipolar transistors (TRs) in a CMOS integrated circuit. CONSTITUTION:The circuit consists of three CMOS inverters I1-I3, three NPN bipolar TRs Q1Q3, and a diode Di. Since the inverters I2, I3 drive a base current of the bipolar TRs Q2, Q3, they can be the same as miniaturized MOS TRs used for circuits other than the output circuit in many cases, and since the bipolar TRs Q1-Q3 have an occupid area remarkably smaller than that of the MOS TRs having the same degree of current drive capability, the area of the entire output circuit is reduced remarkably than that of the output circuit comprising only CMOS TRs. Thus, the miniaturized output having an output voltage of complete TTL level is obtained in this way.

Title: Magnetic recording medium
Inventor: KITAMOTO TATSUJI
IPC: C09D7/12
Filed: 1980-12-11
Abstract: PURPOSE:To obtain amagnetic recording medium which has a high SN ratio and superior reproduction output by using fine magnetic grains having a small length-to-width ratio for an outermost magnetic layer and needlelike magnetic grains having a large length-to-width ratio for the other magnetic layer. CONSTITUTION:For an outermost magnetic layer, rod-shaped ferromagnetic grains which have <=0.3mum mean grain length and a 1-3 length/width ratio are used, so the level of a noise due to discontinuation of magnetization originating from the size of the grains is lowered and the length/width ratio is de- creased to suppress an inclination to laying orientation of the grains. If necessary, an inclination to orientation perpendicular to a surface is provided positively to increase residual magnetization perpendicular to the surface, and  needlelike ferromagnetic grains having a 3 length/width ratio are used for a lower magnetic layer to give an inclination to in-surface orientation, thereby increasing long-wavelength sensitivity.
