Title: Electronic still camera
Inventor: TAKAGISHI HIROAKI
IPC: G03B7/17
Filed: 1987-10-22
Abstract: PURPOSE:To attain photographing using a strobo under low illuminance by detecting the end of charging of the strobo and disabling the changeover of a mode switching means to a infrared-ray photographing mode in response to the detection. CONSTITUTION:Information for changing over the mode to the infrared-ray photographing mode from a pickup intensity detector 5 under low illuminance is given to a controller 6 and a signal instructing the refuge of an infrared-ray cut filter 2 is outputted from the controller 6 accordingly. In this case, when a charge end signal from the strobo 8 to the strobo charge end detection section 9 is sent, the information is sent from the detection section 9 to the controller 7, which does not give the infrared-ray cut filter refuge instruction signal outputted from the controller 6 to the infrared ray cut filter refuge device 4 according to the information and applies switching to block the mode changeover. Thus, since the infrared-ray cut filter is on the optical path even under low illuminance at the time of strobo photographing, the strobo photographing is applied properly.

Title: Speed sensorless vector control system for induction motor
Inventor: MORI MASATO
IPC: H02P27/04
Filed: 1993-10-25
Abstract: PURPOSE:To control an induction motor to a speed coincident with its speed command value by estimating a speed of the motor by using a torque axis component of a secondary magnetic flux estimated value. CONSTITUTION:The speed sensorless vector control system for an induction motor comprises a minimum order magnetic flux observer 4 which inputs primary voltage command values V1d, V1q of stator coordinates of the motor 1, primary current detection values i1d, i1q and motor real speed estimated value omegar. The observer 4 estimates secondary magnetic fluxes lambda2d, lambda2q of stator coordinates, and estimates a motor real speed estimated value omegar by using secondary magnetic flux torque axis component lambda2b in synchronous rotary coordinates after coordinate-converting by a coordinate converter 10. Thus, even if the secondary magnetic flux estimated value has an initial error, the estimated value is converged to a correct value, and hence a real speed estimated value of the motor obtained from the magnetic flux estimated value can always estimate a real speed (true value).

Abstract: PURPOSE:To make a high-frequency device such as a voltage controlled oscillator small in size and light in weight and, to facilitate manufacture thereof by a method wherein a single-crystal lithium borate piezoelectric base having a surface acoustic wave element is joined directly to a semiconductor substrate. CONSTITUTION:A single-crystal lithium borate piezoelectric base 2 joined directly onto an Si substrate 1 has a surface acoustic wave element such as a surface acoustic wave resonator on the surface.

The lithium borate base 2 and the Si substrate 1 are joined directly and the voltage controlled oscillator thus integrated in one body is held in a hermetically sealed vessel. Since an oscillation circuit part and the surface acoustic wave resonator are integrated in one body in this way, attainment of miniaturization in a large degree is enabled and the surface acoustic wave resonator is made easily to be about 1/10 in volume and about 1/5 in weight of the one which is closed hermetically in a vessel and fitted discretely.

Title: Isotope separator
Inventor: HIGUCHI YOSHIYA
IPC: B01D59/48
Filed: 1987-10-23
Abstract: PURPOSE:To make selective ionization easy by applying to a beam of natural atoms a magnetic field whose intensity has a gradient in the direction perpendicular to the direction in which the beam of neutral atoms is going. CONSTITUTION:A beam of neutral atoms of natural uranium is formed and allowed to go through a magnetic field area having components in the direction perpendicular to the direction in which the beam is going. The intensity of the magnetic field in the direction perpendicular to these two directions has been made to have a gradient. A magnetic dipole mu placed in the magnetic field B changes its direction so as to be B mu, and is affected by a force f=DELTA (mu.B). Uranium 235 atoms incident into this magnetic field area have a magnetic dipole efficiency muu235 in their atomic nuclei, with the direction of the muu235 being equally directed to the direction of the magnetic field, and are affected by a force in the direction of Z. This force deflects the uranium 235 atoms and separates them from uranium 238 atoms. Thus, the separating efficiency can be improved.

IPC: H01L21/30
Filed: 1991-09-18
Abstract: PURPOSE:To quickly position a wafer on the optimum image forming plane of a projection optical system with high accuracy by correcting a detection error caused by the surface reflection of a resist film coating the surface of the wafer and reflected light from the surface of the wafer by an oblique incidence AF system with a detected result obtained by an interference AF system. CONSTITUTION:In order to detect the surface of a resist, a Z-stage 3c is moved in the direction in which a wafer W is brought nearer to a second detecting means 6 (interference AF system). Then the stage 3c is stopped at the position where the peak intensity of signal outputs is first detected. Thereafter, a parallel plate 27 is driven to set so that the output of a first detecting means (oblique incidence AF system) can become a prefixed reference signal by driving an X- and Y-stages 3a and 3b under such condition and moving the wafer W to the position immediately below a projection lens PL. Therefore, the wafer can be quickly positioned to the optimum image forming plane of a projection optical system with high accuracy, because the measured value of the first detecting means is corrected with the measured value of the second detecting means.
