Title: Projection exposing device
Inventor: INOUE MITSURU
IPC: G02B27/18
Filed: 1985-10-28
Abstract: PURPOSE:To project and form a mask pattern on a wafer surface at an always constant magnification value by sealing gas with a refractive index different from that of a medium on which an projecting optical system is arranged into a part of the projecting optical system. CONSTITUTION:When an air lens has positive diopter, the diopter of the air lens is increased in accordance with the sealed quantity of gas by sealing the gas having diopter larger than that of air or the diopter of the air lens is increased by sealing gas having diopter less than that of air. The diopter of an air lens having negative diopter can be also changed to the intensity corresponding to a purpose. Thus, The inside of the air lens formed between the lenses of the projection optical system 5 is sealed and then the prescribed volume of gas having a prescribed diopter is sealed into the air lens, so that the diopter of the air lens is properly changed while suppressing the variation of aberration to adjust the projection magnification. Consequently, a pattern on a reticle 1 surface can be projected and exposed on the surface of the wafer at a fixed magnification.

Abstract: PURPOSE: To improve energy transfer efficiency for capacitor charging by providing the inductor of an LC oscillation circuit with an diode in series. CONSTITUTION: A capacitor 3A is peak-charged by LC resonant current through an inductor 5 and a diode 5A connected in series by applying a high voltage from a power source 2, and a capacitor 3B is charged with a high voltage. Pulse current II generated by the charging current permits the secondary side of a pulse transformer 13 to obtain pulse current II' with an increased voltage, and a capacitor 14 is charged. A laser head 15 and a saturable reactor 16 are supplied with magnetically compressed pulse current by the charging voltage. At the time of charging a capacitor 3A, a diode 5A a switches on, and LC resonant current is obtained by the capacitor 3A and the inductor 5. At the time of discharging current from the capacitors 3A and 3B, the diode 5A switches off, and discharge current through the inductor 5 is blocked.  Thus, energy transfer efficiency to the transformer 13 is improved.

Title: Combustion device
Inventor: NAGANO OSAMU
IPC: F23L17/04
Filed: 1988-09-27
Abstract: PURPOSE:To eliminate a fear of return occurring by smoothly discharging exhaust gas obliquely upward and to improve combustion by a method wherein both upper and lower pieces of the tip part of an exhaust top protruded in a feed and exhaust duct are formed in a manner to point obliquely upwardly. CONSTITUTION:In a combustion device, e.g. an FF type hot water feeder, mounted through utilization of a feed and exhaust duct for a collective housing, top and lower pieces 5 and 6, being a tip part and protruded in the feed and exhaust duct 1, of an exhaust top 3 are formed in a manner to point obliquely upward. The protrusion distance, in the feed and exhaust duct 1, of the upper piece 5 is set to a value equal or higher than that of the lower piece 6. In this constitution, when exhaust gas passes through the exhaust top 3 and is discharged in the feed and exhaust duct 1, it flows obliquely upward. This constitution eliminates a fear of the exhaust gas being collided with an opposing wall surface 1a of the duct 1 and returned for incomplete combustion and a fear of the exhaust gas interfering even when a heat source machine is provided in a room at the same floor as that of a surface 1a, and a fear of the exhaust gas being returned toward feed air. Further, a fear of an object and rain entering through the feed and exhaust duct 1 to an exhaust top 3 is eliminated.

IPC: G01D5/36
Filed: 1991-09-20
Abstract: PURPOSE:To stably measure absolute displacement by placing a reflection-type displacement sensor and a slit-type displacement sensor at a 180 deg. pitch on a same circumference of a pipe. CONSTITUTION:A reflection-type displacement sensor H and a slit-type displacement sensor S are provided at a 180 deg. pitch on a same circumference of a pipe 12. In a relation between the amount of displacement of the pipe 12 and photo diode output current in the sensor S, the pipe 12 is vibrating between A and D, and at B, C points where light is shielded by slits 21, 23, the output becomes zero. The point where the output becomes zero is correctly measured in advance to be used for compensate the sensor H. In a relation between the amount of displacement of the pipe 12 and photo diode output current in the sensor H, line 1 is in an initial state and line 2 indicates that a part has been slightly deteriorated, while the pipe 12 is vibrating between A and D. When the slit-type displacement sensor determines that the pipe 12 is located at B, C points, the compensation value which has been correctly measured in advance is used as a reference displacement to compensate output of the reflection-type displacement sensor H to measure an absolute displacement.

IPC: H03D7/02
Filed: 1997-08-23
Abstract: PROBLEM TO BE SOLVED: To improve an S/N ratio of a beat signal made of a transmission wave signal and a reception wave signal. SOLUTION: A high level transmission wave signal and a low level reception wave signal are supplied to a diode 6, while a high level reception wave signal and a low level transmission signal are supplied to a diode 7 respectively with an internal path of a hybrid ring 5. In addition, since forward bias current is supplied from a negative power source 12 only to the diode 6, sensitivity of the diode 6 is reduced, and a noise component due to an oscillator 1 included in the transmission wave signal to be supplied to the diode 6 is hardly detected. On the other hand, the beat signal made of the high level reception wave signal and the low level transmission wave signal is detected with high sensitivity and the S/N ratio of the beat signal to be obtained at an output terminal 8 is improved in the diode 7 to which no bias current is supplied.
