The heating temp. for each single crystal of NdGaO3 and ZnO is in the range of 900 to 1,200 deg.C. However, when the single crystal of NdGaO3 being (110) face orientation is heat-treated, the heating temp. is in the range of 1,000 to 1,100 deg.C. The preferable heating temp. for each single crystal of SrTiO3, Nb: SrTiO3 or LaAlO3 is in the range of 900 to 1,300 deg.C. The heating time for each single crystal is at least 1 h. As the surface of the thus treated single crystal is smooth in atomic level, a high quality single crystal thin film can be prepared.  Further, performance and yield of an electronic device or the like prepared using the thin film is improved as the quality of the thin film is improved. The thin film is also used as a testing substrate for observing a gene (DNA) while placing the gene on the substrate.

Filed: 1994-06-21
Abstract: PURPOSE:To obtain a PWM motor drive apparatus whose control accuracy is increased by a method wherein a mean current in a DC motor driven according to a PWM system is detected with high accuracy. CONSTITUTION:When a CPU 3 closes and drives a transistor Q3 or Q4 by PWM pulses, a sample-and-hold circuit 13 detects the voltage-converted value of an means current in a DC motor 2 to feed back to the CPU 3. The rotation of the DC motor 2 by a triangular wave shaped current can be PWM controlled on the basis of a means current Im which is equal to the arithmetic means value of the highest value and the lowest value of the triangular wave shaped current. Thereby, a high accuracy motor drive operation can be performed irrespective of the pulse width of the PWM pulses which changes dynamically according to a control deviation.

Abstract: PURPOSE:To obtain an image deviation information which depends on an altitude in reference to the ground without requiring a separate ground data, etc., from correlation of outputs by allowing wavelength characteristics of at least one set of elements out of optical detection elements which are placed in parallel to be equal. CONSTITUTION:Filters 21, 22, 23, and 21n with different transmission wavelength regions are placed on a front surface of four rows of optical detection elements 11, 12, 13, and 11n which are placed in parallel on an image surface of an image-forming optical system 1 consisting of an objective lens, a reflection objective optical system, etc. However, a transmission wavelength region of the filters 21 and 21n of one set of elements 11 and 11n at inside and outside rows of these element row is equal. When this device moves along with an artificial satellite, an image of a target on the ground is scanned in a direction for crossing four rows of elements 11, 12, 13, and 11n. At this time, an altitude in reference to the ground is detected from an output time difference, a relative interval, and a traveling speed of the element 11 and the element 11n and an image deviation information which depends on it is obtained. By performing compensation processing for each wavelength based on it, a wavelength resolution image of an object on the ground without any distortion between wavelengths can be obtained.

Only the modulated color light is transmitted by the function for selectively transmitting (or selectively reflecting) the color light, which is possessed by the inserted dichroic filter 104, and leakage light emitted through the prism 105 is reflected to a color synthesizing means side. Thus, adverse influence such as the malfunction caused by the leakage light exerted on the back surface of the liquid crystal light valve 101 is eliminated.
