IPC: G02B13/18
Filed: 1990-04-06
Abstract: PURPOSE:To obtain the small-sized zoom lens which has high optical performance and is short in overall lens length by specifying the lens constitution of 1st - 3rd lens groups. CONSTITUTION:The 1st group I is composed of three lenses in specific shapes and a meniscus lens which has its convex surface on the image side is used as, specially, a 13th lens to have two positive lenses. The 2nd group II consists of three independent lenses in the specific shapes and, specially, a 22th lens and a 23th lens are constituted independently. The 3rd group III consists of a single negative lens having a refractive surface which has larger refracting power on the object side than on the image plane side. Consequently, the small- sized zoom lens which has a small generation quantity of high-order aberrations and high optical performance over the entire power variation range and is short in overall length is obtained.

Title: Formation of interface
Inventor: NIWA MASAAKI
IPC: H01L27/12
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To smooth the interface between a silicon layer and a buried oxide film layer of a silicon-on-insulator(SOI). SOLUTION: A direct current is applied to electrical heating electrode regions 17, 18 so as to perform heating. Migration of surface atoms may be controlled during electrical heating, and the surface atoms migrate in a direction of the flowing current. In the case of an SOI substrate, sublimation of SiO occurs along with migration of silicon atoms on the surface at the time of electrical heating. However, since silicon is formed on both sides of the interface of a buried oxide film, electrical heating does not cause sublimation of SiO but causes interface atoms to migrate in the direction of the current. Since the majority of electrical heating current components flow through the substrate surface portion, the electrical heating current flows to an upper layer silicon.  Therefore, migration of interface atoms in the current direction due to electrical heating occurs on the buried oxide film interface as well as the surface of the upper layer silicon. Thus, the silicon-buried oxide film interface is smoothed, realizing smoothing of the interface at the atomic level.

Title: Reader
Inventor: OGATA NOBUAKI
IPC: H04N1/04
Filed: 1986-04-22
Abstract: PURPOSE:To adapt a linear pulse motor to the movement of an optical unit or an original base in a reader by bringing the flange of the guide roller of the linear pulse motor into contact with the side surface of a fixed scale under pressing and moving. CONSTITUTION:A spring 31 is inserted between the guide roller 27 and the fixed adapter 28 and the flange 27B of the guide roller 27 at both sides is brought into contact with the side surface of the fixed scale 24 under pressing.

Title: Heat-treatment device for semiconductor substrate
Inventor: OKUBO KOICHI
IPC: H01L21/26
Filed: 1985-04-30
Abstract: PURPOSE:To highly accurately control the temperature raise profile for a substrate by a method wherein a filter performing the selective absorption of the heating light is arranged between a heater and a semiconductor substrate, and the wavelength of the heating light to be irradiated on the substrate is selectively selected so as to selectively heat the specific impurity. CONSTITUTION:Over a semiconductor substrate 3, a heater 8 irradiating the heating light on a substrate 3 is mounted on the lower side of a box cover 7. A filter 9 is arranged between the heater 8 and the substrate 3. The filter 9 selectively absorbs the light of specific wavelength out of the light irradiated from the heater 8 and pass the light of other wavelength, with the heating of the substrate 3 accomplished only by the light passing through. Thus, it is made possible to irradiate the light of specific wavelength by arbitrary selecting a filter 9, thereby allowing an arbitrary temperature raise profile to be set.

IPC: G01F23/26
Filed: 1987-04-17
Abstract: PURPOSE:To automatically perform the zero adjustment of output, by providing an automatic phase shifting circuit and feeding back the output of a low-band filter circuit. CONSTITUTION:When the phase shift of an input signal es is generated with the positional change of a sampling probe 6 by the movement thereof, the output signal e0 of a low-band filter circuit 50 and the output signal Vs of an amplifying circuit 55 are successively generated. On the basis of these signals, a zero setting signal 80 of an active state is outputted from a CPU 75 in order to perform automatic zero adjustment to be applied to the analogue switch circuit 81 of an automatic phase shifting circuit 45. Hereupon, the signal Vs is applied to an error amplifying circuit 82 through the circuit 81 and held to a sample holding circuit 83 as an amplifying signal VE. The signal VE is applied to a synchronous rectifying circuit 40 as a reference signal eR by an adder circuit 87 through a multiplier circuit 84. This signal eR is controlled so as to always have phase difference of 90 deg. from the signal eS by the action of the circuit 45. The output of the circuit 40 becomes zero at the time of this phase difference. By this constitution, when the signal Vs is generated in the circuit 55, automatic control which brings said signal to zero is performed.

Title: Molten steel level control method in mold in continuous casting machine
Inventor: FUKUMOTO KATSUTOSHI
IPC: B22D11/18
Filed: 1978-07-31
Abstract: PURPOSE: To eliminate the defects of molten steel level control in mold by detecting the end of pouring from ladle and reducing the number of revolutions of rolls.  
     CONSTITUTION: Now, when pouring from a ladle 40 ends, a switch 45 detects the end and the ladle end detecting signal operates. Hence, a relay 32 goes OFF and the output 12 of a relay 30 is shifted to the output side of delay characteristics 31. This results in that the roll revolution number set value 12 decreases gradually, thus overdrawing with drawing rolls 7 as with conventional machines does not occur. Hence, arriving at the lower limit value of the level in the mold 2 is obviated and the level control in the mold 2 may be accomplished smoothly.
