Title: Constant pressure hydraulic device
Inventor: YOSHIDA SHIGEO
IPC: B66D1/44
Filed: 1986-03-31
Abstract: PURPOSE:To aim at energy saving, by constituting liquid supply paths leading to hydraulic driving devices of hydraulic circuits with two or more systems of different pressures. CONSTITUTION:Hydraulic driving devices 1 and a hydraulic supply 2 are connected together, by a high pressure path 3 which is a path for an actuation liquid discharged from the hydraulic supply 2 under a high pressure, a low pressure path 4 which is a path for the actuation liquid discharged from the hydraulic supply 2 under a low pressure, and a return path 5 which is a path for return of the actuation liquid ejected from the hydraulic driving devices 1 respectively.

Title: Manufacture of semiconductor element and projection aligner
Inventor: ICHIHARA YUTAKA
IPC: G02B27/28
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a reduction projection optical system in which various aberrations such as astigmatism, distortion aberration, chromatic aberration and the like are corrected satisfactorily by a method wherein, even in a specific region in which a projection lens cannot be formed of only a refraction system, a polarization beam splitter and a quarter-wave plate are combined with a reflection system and the refraction system. SOLUTION: A luminous flux from a first plate 10 which is illuminated with polarized light from an illumination optical system at a wavelength region of 300nm or lower is converted into a parallel luminous flux by using a first lens group G1,. so as to be incident on a polarization beam splitter 11. A reflected luminous flux from the splitter 11 is condensed on a second plane 20 by using a third lens group G3. The polarized light which is transmitted through the polarization beam splitter 11 passes through a quarter-wave plate 12, it is diverged by using a second lens group G2 with negative refracting power, so as to be incident on a concave reflecting mirror 13. A luminous flux which is reflected by the reflecting mirror 13 passes through the second lens group G2, the quarter-wave plate 12, the polarization beam splitter 11 and the third lens group G3.  As a result, the reduced image of a reticle pattern can be projected clearly on the second plane 20 which corresponds to a wafer plane.

Title: Quartz oscillator
Inventor: IWAKURA YOSHIKI
IPC: H03B5/36
Filed: 1981-05-12
Abstract: PURPOSE:To obtain low power and high accuracy, by decreasing the resistance component of a substrate being one electrode to an MOS capacitor which is built-in capacitor, in incorporating an externally mounted resonance capacitor of an oscillator in an IC. CONSTITUTION:A semiconductor region 7 is a very dense P-Well region, >=10<18>/ cm<2> as the same pattern as a P-Well region 4 and the thickness is 0.5-1.0mum. Thus, the substantial resistance of the substrate can be realized as <= several ohms through the provision of a P type semiconductor layer 5 around the region. Thus, the resistance becomes sufficiently lower than a crystal impedance of a high frequency quartz oscillator and the power loss can be neglected. When an MOS capacitor with such constitution is taken as a resonance capacitor for an oscillator, since the change in the capacitance to a gate voltage can be flat, the battery voltage dependancy of the oscillation frequency is less.

Title: Musical tone specifying device and electronic wind instrument using same
Inventor: MURATA YOSHIYUKI
IPC: G10H1/38
Filed: 1989-03-23
Abstract: PURPOSE:To improve the operability by allowing a musical tone information generating means to generate musical tone information regarding the pitch of a single tone or the pitch of respective constituent tones of a chord specified by the combination state of switches of a pitch specifying means according to the decision result of a decision means. CONSTITUTION:When switches of the pitch specifying means 21 are turned on, for example selectively in combination with the plural switches, the decision means 30 detects the states of the respective switches of the pitch specifying means 21 to discriminate whether the single tone or chord is specified according to the combination state of the switches in the on state. Then a pitch information generating means 30 generates pitch information regarding the pitch of the single tone or the pitch of the respective constituent tones of the chord specified by the combination of the switches of the pitch specifying means 21. Consequently, the plural switches of the pitch specifying means 21 are operated in combination to specify the single tone or chord.

Title: Projecting type display device
Inventor: MATSUO MASATAKE
IPC: H04N9/31
Filed: 1989-03-23
Abstract: PURPOSE:To arrange the intensity distribution of a light incident on each transmitting type light value between respective color lights, to heighten gradation display ability and to improve the quality of a video displayed on a screen by arranging a projected lens on at least one of the optical paths of three transmitting type light values. CONSTITUTION:The projected lens is arranged on at least one of the three transmitting type light values for R, G and B. For example, if the projected lens 8 is arranged in front of the transmitting type light bulb 4 for the R, the intensity distribution of a light which emits from the transmitting type light value 4 for the R becomes identical with the intensity distribution of a light which emits from the transmitting type light value for the B by the action of the projected lens 8 and an in-screen brightness correcting signal for the R becomes identical with a brightness correcting signal for the B. Thus a circuit becomes simple and the brightness distribution of an emitting light is practically improved. Besides, providing signals for correcting brightness between color lights for obtaining a white balance becomes unnecessary and the lowering of the gradation display ability is eliminated. Thus, display quality on the screen 7 is improved.

Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a melt level detector capable of simply and precisely detecting a melt level and also to provide a melt level detection method using the detector. SOLUTION: The detection method using this detector for detecting the melt level of a melt surface in a CZ(Czochralski) furnace on the basis of the principle of triangulation, comprises: moving the projection position on the melt surface of a laser beam 2 from a laser beam irradiator, in the radial direction of a crucible 14 in the CZ furnace, to scan such a projection position that the laser beam 2 reflected from the melt surface is received by a laser beam receiver; and setting the projection position to this position. Thus, since an appropriate melt surface part for detecting a melt level 3 is found by scanning the projection angle within a very narrow range and measurement of the melt level 3 is performed in this appropriate part, complication of the detector can be avoided and detection of the melt level 3 is performed in such a state that the influence of noise caused in the melt surface, on the detection is reduced.

Title: Method for controlling particle size in granulation
Inventor: TATEBAYASHI JUN
IPC: B01J2/16
Filed: 1986-03-28
Abstract: PURPOSE:To make it possible to determine the particle size of a granulated substance without sampling the same, in a granulation apparatus consisting of a granulation furnace and a dust collector, by controlling the temp. of a bed on the basis of the temp. of a recirculated particulate material so as to make the temp. of said particulate material constant. CONSTITUTION:The raw material powder charged in a jet stream bed furnace 1 is self-granulated in the furnace I and a granule having a small particle size flies out from the furnace 1 to be collected by a cyclone 3 and is again returned to the furnace 1. The self-granulated substance not flying out from the furnace 1 grows in its particle size to be discharged out of the furnace 1. Because the flying-out quantity from the furnace 1 is much when a particle size is fine and recirculation quantity increases, the temp. T1 of the powder becomes higher than set temp. When the particle size is coarse, the temp. T1 becomes lower than the set temp. Hereupon, the recirculation quantity of the powder is grasped on the basis of the temp. T1 of the powder and, if the temp. T1 rises to become higher than the set temp., the signal showing this state is inputted to an operator 7 and a large quantity of fuel is sent on the basis of the signal outputted to raise the temp. of a bed to promote granulation. Contrarily, if the temp. T1 becomes lower than the set temp., the supply quantity of fuel is reduced.
