Title: Induction motor
Inventor: SATOU TETSUYA
IPC: H02K17/16
Filed: 1978-12-22
Abstract: PURPOSE: To prevent current increase in the case a primary voltage is decreased and to prevent temperature rise by keeping the ratio between the primary resistance and the secondary resistance that is converted into the primary basis within a specified range, in an induction motor wherein the number of revolution is controlled by controlling the primary voltage.  
     CONSTITUTION: The amounts of flow or pressure of wind and hydraulic machines such as pumps, ventilators, and the like, wherein the loads increase with the increase in the number of revolution, is controlled by varying the primary voltage of an induction motor. For example, in the case an induction motor is applied to a canned motor pump, a stator 2 and a squirrel-cage rotor 7 of the induction motor are hermetically enclosed by a stator can 6 and a rotor can 13, respectively. In order to prevent the current increase when the primary current is decreased, the cross-sectional areas of a secondary conductor 10 and an end ring 12 are reduced, and the ratio between the primary resistance and the secondary resistance that is converted into the primary basis is set at 1:2∼1:4.

Title: Imaging device
Inventor: MURANO SHUNJI
IPC: H01L27/14
Filed: 1992-05-29
Abstract: PURPOSE:To contrive to miniaturize the size of an image chip by a method wherein bonding pads are arranged parallel and a projection is not provided in the opposite angle between the bonding pads. CONSTITUTION:As a diameter of at least about 80 is required in pads 10, 12, the pads 10, 12 are arranged parallel. A clearance 13 of a light-emitting part 4 and a pad 12 is 25mum and 15mum shorter than usual, and a diameter of the pads 10, 12 is 110mum with a circle. Further, the minimum interval 15 between the pads 10, 12 in the opposite angle direction is 20mum the same as usual. But, as the pad is circular, a length between centers of the pads in the vertical direction is 92mum (130 is divided by 1.414), and as compared with conventional 130mum, it is shortened by 38mum. Also, a clearance 17 of the pad 10 and a chip 2 is changed from 30mum to 25mum, namely shortened by 5mum. A total reduction width of a length 1 of the chip 2 is 73mum. As the reduction in the longitudinal direction of the chip 2 cannot be made, an area of the chip 2 can be reduced by 18%.

Title: Semiconductor light emitting element
Inventor: OKUDA HIROSHI
IPC: H01L33/30
Filed: 1984-08-03
Abstract: PURPOSE:To reduce the half value width of emission spectra by increasing the response speed and the luminous output by a method wherein a p-n junction is positioned at the interface between an n-InP clad layer and a non-doped In1-x- GaxAs1-yPy active layer or in its neighborhood. CONSTITUTION:After the In1-xGaxAs1-yPy active layer 3 which is not doped is epitaxially grown, a p-In1-xGaxAs1-yPy active layer 4 which is doped with Zn and the p-InP clad layer 5 are epitaxially grown in succession, when the Zn in the Zn-doped active layer 4 diffuses into the non-doped active layer 3. As a result, the p-n junction is formed in the neighborhood of the interface between the active layer 3 and the n-InP clad layer 2. This allows injected carriers to be completely confined in the active layers 3 and 4 instead of outflow to the n-InP clad layer 2; therefore, all of the carriers are contributed in light emission, and the luminous output increases.

Title: Method of analyzing interface
Inventor: WATABE KOJI
IPC: G01N21/63
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To easily and nondestructively evaluate a semiconductor interface in the atmosphere without depending on film thickness and specify a chemical bonding seed or the like in the interface by measuring the intensity of generated higher harmonics while changing the wavelength of a laser beam. SOLUTION: The laser beam from a light source 1 is incident on a sample 4 at 45 deg. while passing it through the OPO 2 of a wavelength converting device to change the wavelength. In this case, the wavelength is continuously changed within a desired range. The second higher harmonics generated by the sample 4 are converged by a lens 5, passed through a polarizer 6 to select a polarized component, and then received by a spectroscope 7. The second harmonic intensity to the incident wavelength is automatically read by a PC(personal computer) 9 through a digital oscilloscope 8. The PC 9 determines wavelengths of one or a plurality of peaks of the second harmonic intensity generated from the interface, and specifies a chemical bonding seed and its composition ratio in the interface.

Abstract: PURPOSE:To detect overrotation even if anything trouble happens in a revolution detecting system as well as to make the speed control of a windmill wing attainable, by installing a rotary plate inside a device altering a pitch of the windmill wing, while attaching a centrifugal switch, using a weight, to one side of the rotary plate. CONSTITUTION:When a windmill wing 4 rotated, a rotary shaft 1 rotates as well, whereby the number of revolution is detected by a tachometer 20 and transmitted to a control part 21. When the revolution in the wing comes high due to a strong wind, speed control takes place by the control part 21. That is to say, an electric cylinder 11 is energized with a continuous rating current, causing a shaft 12 to be shortened in length, and a wing shaft 5 is twisted via a rotary plate 8, an operating shaft 7, a connecting rod 9 and a wing shaft arm 10 whereby a wing pitch of the windmill wing 4 varies to some extent and a rise in revolution is thus checked. In this case, when anything trouble happens in a revolution detecting system 20a, a centrifugal switch 13 attached to one side of a rotary piece 8 is operated. That is, each of weights 17 and 17' is expanded outside by centrifugal force, operating a limit switch 19, and an electric signal is transmitted to the control part 21.
