Title: Waveform shaping circuit
Inventor: ROBAATO EMU BATEI
IPC: G11B20/10
Filed: 1983-07-08
Abstract: PURPOSE:To exclude the noises contained in a raw signal, by producing a digital output signal corresponding to the peak of the data stored on a magnetic medium through an output circuit which is triggered at a single edge part by means of the signal produced from the output circuit. CONSTITUTION:An input signal 90 is sent to an absolute value circuit 110 through a buffer amplifier 100, and the circuit 100 generates an output 115 approximately equal to the mathematical absolute value of the signal 90. With use of the circuit 110, a single delay line can be used to the signals going toward positive and negative directions. As a result, the timing error between both polarity signals is substantially set at 0. The output 115 of the circuit 110 drives a differentiation circuit 120 and an input 131 of a comparator 130. The circuit 120 produces a differential output 125 equivalent to a time differential d/dt of the signal 90. An output signal 165 and its reverse signal 165' of a comparator 160 are connected to a monostable multivibrator circuit 170 which is triggered only by the edge parts of signals 165 and 165' corresponding to the peak of the signal 90.

Title: Manufacture of compound semiconductor epitaxial wafer
Inventor: NAGAO SHOICHI
IPC: H01L21/205
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To improve two-dimensional electron gas mobility by performing the crystal growth of a spacer layer that is inserted between a natural InGaAs layer that becomes an electron running layer and an n-AlGaAs layer that becomes a carrier supply layer with a V/III ratio being equal to or more than a specific value. SOLUTION: A natural AlGaAs buffer layer 2, a natural InGaAs electron running layer 3, a natural AlGaAs spacer layer 4, and an Si-doped n-AlGaAs carrier supply layer 5 are successively formed on a GaAs substrate 1. An HEMT structure epitaxial wafer for evaluating two-dimensional electron gas mobility is allowed to grow by the MOVPE method so that a V/III ratio for allowing the natural AlGaAs spacer layer 4 to grow becomes 110 or higher. Mobility gradually increases until the V/III ratio becomes 110, while the mobility becomes nearly constant when the V/III ratio is equal to or more than 110, thus improving the two-dimensional electron gas mobility of an InGaAs/AlGaAs-family HEMT structure epitaxial wafer.

Title: Vibration proof optical system
Inventor: MOROOKA MASARU
IPC: G02B27/64
Filed: 1994-06-07
Abstract: PURPOSE:To provide a small sized vibration proof optical system with simple configuration capable of excellently and quickly correcting an image blur without deteriorating the image forming performance at the time of shake of a photographing lens. CONSTITUTION:Main lens systems G1-G4 forming an object image and a meniscus lens L with an image plane faced to a concave surface are arranged between the main lens systems G1-G4 and an image plane and the lens L is inclined to the optical axis, so that the image blur of a photographed image generated by the tilt of a whole system of the photographing lens is corrected. Since the image blur correction lens L thus arranged has a lens shape of reducing an eccentric aberration coefficient, the generation of the 'blur of a point image' and the 'extension and contraction of the image' are decreased and excellent image forming performance is enabled at the time of image blur. Consequently, the variation of aberrations due to the rotation of the image blur correction lens L is decreased and the excellent image forming performance is obtained even when the shake of the photographing optical system is generated.

Title: Discharge device for powdery granule
Inventor: OTSUKA HIDEMITSU
IPC: B65G65/48
Filed: 1985-06-11
Abstract: PURPOSE:To eliminate a bridge or rat hole phenomenon in an easy manner, by installing a spiral plate in an inner surface of the lower hopper fitly installed in a lower part of a hopper body, making it rotable, while installing each spiral plate of the specified width in an inner circumferential surface of a discharge port at more than a fixed pitch. CONSTITUTION:Powdery granules projected out of a top part of a hopper body 1 drop in a lower hopper 2, reaching to a discharge port 2a, and since each plate 11 of more than half of a diameter of an opening part in width is installed in spiral form at more than one pitch, the plate 11 serves as a gate whereby these powdery granules are not naturally discharged, and they are accumulated in the hopper. When these granules are discharged out, a motor 9 is started, and when the lower hopper 2 is rotated, these powdery granules are extruded downward by a screw conveyor function of a spiral plate 10, and simultaneously powdery granules inside the discharge port 2a also are discharged out by action of the spiral plate 11, and while rotation of the lower hopper 2 is continues, this discharge operation takes place in succession. In addition, a baffle plate 12 is installed in an inner circumferential surface of a lower end of the body 1 so that these powdery granules smoothly flow in succession, thus a bridge or rat hole phenomenon is prevented from occurring.

Filed: 1986-05-30
Abstract: PURPOSE:To obtain a halftone picture free from distortions even with a picture output device having different dot densities between the main scan and subscan directions, by segmenting regularly submatrices of prescribed sizes which are analogous to a specific master matrix. CONSTITUTION:A density pattern of a desired number of gradations is set by a rectangular matrix where the ratio between the numbers of dots on the sides corresponding to each scan direction is equal to the ratio between dot densities of each scan direction. This density pattern is defined as a master matrix. Then the density pattern is outputted while the submatrices of prescribed sizes which are analogous to the master matrix are regularly segmented. That is, a CPU 10 receives the picture data from a host computer 200 through an I/F port 40 and defines a data memory 12 as a working memory according to the program of a program memory 11. Then the CPU 10 segments a desired density pattern of a density pattern memory 30 in the segmenting order of submatrices. This output picture is evolved on a page memory 20 as a bit image pattern and then outputted to a plotter 300.

Title: Steam separator
Inventor: FUJIMOTO KIYOSHI
IPC: G21C15/16
Filed: 1998-05-08
Abstract: PROBLEM TO BE SOLVED: To maintain or improve steam separation performance by reducing the pressure loss in a steam separator. SOLUTION: The flow area in a swirler 1 is widened and reduced in the flowing direction. Then, in a steam separator having 3 steps of a pick-off ring, the diameter of the most upstream first pick-off ring 7a is made smaller than that of the second pick-off ring 7b and the diameter of the most downstream third pick-off ring 7c is made larger than that of the second pick-off ring 7b. As the average flow velocity in the swirler can be reduced, friction loss and acceleration loss can be reduced and thus the pressure loss of the whole swirler can be reduced. Also by reducing the diameter of the most downstream third pick-off ring, carry-over can be reduced with the minimum increases of pressure loss.

IPC: G02F1/13
Filed: 1982-07-20
Abstract: PURPOSE:To shut off thoroughly incident rays and to utilize a titled device as a shutter with little loss in the quantity of light by providing a means for heating a homeotropically oriented liquid crystal sandwiched between a pair of substrates and a means for making incident thereto in a specific angle range. CONSTITUTION:Transparent substrates 1, 2 having a refractive index ng formed with transparent resistors 4, 5 thereon sandwich a liquid crystal 3. The refractive index n0 of the ordinary rays of the liquid crystal and the refractive index nISO of the liquid phase have the relation smaller than the refractive index ng. All of the incident light having sin<-1>A incident angle or above are totally reflected light 10 when the liquid crystal 3 maintains a homeotropic orientation V at n0/ng=A, nISO/ng=B. If the resistors 4, 5 are electrically heated, the liquid crystal 3 is transferred to the liquid phase I having isotropy, and the incident light having less than sin<-1>B angle is transmitted as light 9. The incident light 8 is thus transmitted or totally reflected as desired and since no polarizing plates are used, the titled device is usable as a liquid crystal-optical shutter permitting high speed control with little loss in the quantity of light.
