Title: Production of silicon single crystal and wafer for forming semiconductor
Inventor: YOKOYAMA TAKASHI
IPC: C30B15/14
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To extend the elimination effect of hydrogen on void defects to the depths of the wafer without changing the conditions of hydrogen treatment of the wafer and to inhibit clusters from existing in the wafer by pulling up a silicon single crystal while controlling conditions causing oxygen-induced stacking faults(OSF) in the oxidative heat treatment of a wafer formed from the single crystal. SOLUTION: In this production process, a silicon single crystal is pulled up under conditions such that the radius of an OSF ring (ringlike OSF) caused in the oxidative heat treatment of a wafer, is a value falling in the range of from a peripheral region of the wafer, in which OSF begin to be caused, to a circular region having a radius equivalent to a half of the wafer radius, more specifically, under conditions such that V/G is <=0.25 mm2/ deg.C.min (wherein: V is the pulling-up rate (mm/min) of the single crystal being grown; and G is the temperature gradient ( deg.C/mm) within the single crystal in the direction of the crystal axis in the vicinity of the silicon melting point) and the radius of the OSF ring is equal to or larger than a half of the wafer radius.  This wafer which is formed from the silicon single crystal thus produced, is subjected to heat treatment using gaseous hydrogen or a non-oxidizing gas to eliminate void defects in the wafer.

Title: Capacity type measuring device
Inventor: PIITAA SUTORATSUKU
IPC: G01D5/24
Filed: 1994-04-18
Abstract: PURPOSE: To improve the measuring accuracy of a capacitive measuring device, particularly a length measuring device, which has a scale part, sending electrodes movable relative to the scale part, and a scanning unit supporting at least one receiving electrode. CONSTITUTION: A transmission signal is applied to sending electrodes S0 to S7 via a synchronous modulator 7, and an input signal is guided via a demodulator 14. The same modulation frequency is utilized for modulation and demodulation. When a scanning unit 3 travels relative to a scale part 1, the fundamental frequency of the input signal matches the travel speed and changes with respect to the fundamental frequency of the transmission signal. This frequency change is evaluated by evaluating circuit 18, 19, 20 in order to display the distance traveled.

Title: Rotary heat storage type heat exchanger
Inventor: IZUMI TAKAO
IPC: F28D19/04
Filed: 1983-05-07
Abstract: PURPOSE:To raise the reliability and durability of a heat exchanger by preventing damage to and delamination of bonded cores by greatly lowering stress to be applied to the drive force receiver by a method in which projections are formed on fine-ceramic ring parts buried in the core slide face. CONSTITUTION:Projections 10A and integrally formed on ring parts 10 made of a heat- and wear-resistant material, e.g., fine ceramics, drive force is transmitted from the projections 4 of ringed gears 2 to the projections 10A through an elastomer 5. When the face 10C of the ringed part 10 is bonded to a groove 1 formed in the core 1 by a ceramic cement, for example, the drive force transmitted to the projections 10A is transmitted to the core 1 which is in turn driven rotationally. Since the core drive force is received by the whole surface of the bonded portion of the ringed part 10, stress to be applied to the bonded portion can be greatly reduced.

Filed: 1988-03-31
Abstract: PURPOSE:To stabilize a center wavelength and the power in a short time by providing a control means to change a transmission wavelength of other etalons excluding an etalon of a minimum free spectral range. CONSTITUTION:When an oscillation of an apparatus is started, a CPU 302 reads out an oscillation center frequency lambda detected with an oscillation center wavelength and center wavelength power detector 301 and computes a deviation DELTAlambdabetween this oscillation center frequency lambda and a desired wavelength lambda0. The CPU 302 compares an absolute value ¦DELTAlambda¦ of the deviation DELTAlambda with 1/2 of a smaller FSR1 of an etalon and judges whether a compared value is 1/2 or higher. When the oscillation center wavelength deviates toward the short wavelength side including the desired wavelength lambda0, the CPU 302 judges that the deviation is not DELTAlambda>0 and finds this displacement amount DELTAlambdaE2; it controls a transmission wavelength of other etalons excluding the etalon of the smaller FSR1 in such a way that the wavelength is shifted toward the long wavelength side by the diaplacement amount DELTAlambdaE2=2.FSR1.

Abstract: PROBLEM TO BE SOLVED: To reduce cost by measuring a pitching angle from the height of a sensor from the road surface when electromagnetic field indicators installed at specified spaces are in first and second specified positions from the sensor of a vehicle, and also from a space between the specified positions. SOLUTION: Which of sensors 2a-2e is closest to a magnet 4 is judged, and a signal of each Hall element of the closest sensor is used for operation. Whether the magnet 4 came into a position 15cm in front of the sensor is judged. The signals of the respective longitudinal and lateral Hall elements at the time of the magnet 4 being positioned 15cm ahead in a proceeding direction from the discriminated sensor closest to the magnet 4 are projected on a map so as to obtain the vertical distance between the sensor and the upper end part of the magnet 4, that is, the road surface, at that time. In the same way, a state of the magnet 4 being positioned 15cm backward is detected, and the distance at that time, that is, the vertical distance between the sensor and the road surface, is obtained.  The pitching angle of a vehicle can be obtained by operation using both vertical distance and a space (30cm) between two longitudinal points.
