Title: Education system by computer support and method for education
Inventor: DANIEL G BOBURO
IPC: G06F17/00
Filed: 1999-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a system and method for interactive computer support education. SOLUTION: An interactive customized educational application prepares educational resources by using an intelligent form and embedded data processing (203) in this education system. A learner puts marks on the educational resources (204), and returns them to this system by scanning them (205). The marks are identified by scanning, and the result is transferred to an educational application (206). The educational application decides a proper interactive course including the educational material of answers to be printed out for the learner (207). Thus, the learner can interact with a computer in a class room by using paper being a familiar medium. Also, each learner can simultaneously enjoy a service, and the educational application for making it easy for parents and school administrators to get involved in the educational process (210) can be prepared in this system.

Title: Semiconductor laser wavelength stabilizing equipment
Inventor: UEDA TOSHITSUGU
IPC: H01S5/068
Filed: 1986-11-28
Abstract: PURPOSE:To enable controlling the difference of two wavelengths in high accuracy by using a common wavelength selection element for stabilizing the wavelengths against two semiconductor laser diodes. CONSTITUTION:The laser light irradiated from two semiconductor laser diodes LD1, LD2 is superposed after making the planes of polarization perpendicular and part of the superposed laser light enters in a wavelength selection element 3 via a halt mirror HMR1. Part of the laser light which enters in the element 3 is separated and enters in a beam splitter PBS3, the laser light from the element 3 enters in a beam splitter PBS4 and the laser light before and behind the element 3 is separated by using the difference of the planes of polarization. The difference of the intensity of light before and behind the element 3 against each wavelength laser light is sought and the output is fed back to the driving circuit of the laser diode via integrators 5, 15 each. In this way, two sorts of laser light are guided to a feedback circuit respectively without mutually interfered and each wavelength is stabilized independently for two semiconductor laser diodes.

Inventor: MASUDA HIROYUKI
IPC: H02M7/48
Filed: 1989-10-31
Abstract: PURPOSE:To reduce the cost and the size of a high voltage pulse power supply by alternately firing P side and N side electric valves in a power inverting section thereby consuming energy in a DC capacitor through a snubber resistor. CONSTITUTION:Upon firing of a P side GTO 43, charges flow from a P side snubber capacitor 412 through a snubber resistor 413 and the GTO 43, and the energy in the snubber capacitor 412 is consumed by the snubber resistor 413. Upon subsequent tiring of an N side GTO 44, energy in a snubber capacitor 422 is consumed by a snubber resistor 423. When the P side and N side GTOs 43, 44 are fired simultaneously and alternately, energy in a capacitor 3 is con sumed by the snubber resistors 412, 423. Consequently, the GTO elements 43, 44 function as conventional switches whereas the snubber resistors 413, 423 function as discharging resistors.

Title: Pressure control device
Inventor: NAKANO TATSUSHI
IPC: B60T15/36
Filed: 1991-10-04
Abstract: PURPOSE:To reduce noises in a car by giving the time interval of pulse currents such a length that the synthesized wave of a plurality of pressure waves of a solenoid valve device based on the pulse currents does not have the same frequency component as the resonance frequency of either of a plurality of vibrating elements which vibrate on the basis of the synthesized wave of the car. CONSTITUTION:The fundamental pressure change pulse current is in principle divided into two split transform pulse currents and supplied to solenoid-operated direction selecting valves 34, 36, 70, 72. In case the duration Tp of the fundamental transform pulse current is too long when the relationship between the cycle time Tc and pulse interval t1 concerns, the fundamental transform pulse current is as exeption supplied to the direction selecting valves unchangedly. This enables proper setting of the time interval of two pulse currents, and thereby one fundamental wave in the pressure waves based on the foregoing pulse current and one fundamental wave in the pressure waves based on the subsequent pulse current, which both have the same frequency as the frequency of intra-car noises to be reduced, cancel each other, and thus the noises in the car can be reduced.

Abstract: PURPOSE:To miniaturize a gas discharge reaction apparatus and to promote discharge reaction, by applying alternating high voltage between a conductive electrode plate and a counter electrode plate and allowing raw material gas to pass through a passage. CONSTITUTION:In applying alternating high voltage across an electrode plate 2 and an opposed electrode 3, relatively low voltage is applied at first and said voltage is made gradually high.
