Patent JP-S5656929-A (JP)
Title: Apparatus for controlling exhaust-gas by-pass valve for turbocharger
Inventor: YAMANE TAKESHI
IPC: F02B37/18
Filed: 1979-10-16
Abstract: PURPOSE: To prevent that air not passed through an intake throttle valve is supplied to engine even if accuracy of the axial rail of a rod passed through a pressure chamber of a diaphragm actuator, by breaking communication between the inlet portion of a compressor and the pressure chamber of said diaphragm actuator at the time of low-speed, low-load operation of engine.  
     CONSTITUTION: Since an intake throttle valve 2 is kept in its almost fully closed position during low-speed, low-load operation of engine, the amount of intake air is reduced if a compressor 1a is rotated at a high speed, so that pressure in downstream intake pipe 3b is lowered. When the pressure in the downstream intake pipe 3b becomes lower than a predetermined level, communication between an air pipe 11 and a pressure chamber 4a of an exhaust-gas by-pass valve 8 is broken by a shut-off valve 12 provided in a signalling pipe 14. Therefore, air leaked into pressure chamber 4a through a seal 10 with a rod 9 passed therethrough by the function of a high negative pressure in pipe 3b is prevented from being supplied to engine by means of shut-off valve 12, so that low-speed, low-load operation of engine can be rendered stable.

Title: Device for setting gain value of servo control system for optical pickup actuator
Inventor: BEPPU SHIGEYUKI
IPC: G11B21/10
Filed: 1993-05-10
Abstract: PURPOSE:To make the servo performance of several device uniform by severally setting the gain value of a servo control system at every reproducing device when the dispersion in the sensitivity of the actuator of an optical pickup exists at every reproducing device. CONSTITUTION:Switches S1-S4 are connected to the input port of a CPU 17. Then, according to the switching states of the switches S1-S4, the gain setting value of an actuator coil 15 in the direction of focusing among the gain setting values outputted from the CPU 17 to a gain setting/phase compensation circuit 9 is made revisable. Further, according to the switching states of the switches S3, S4, the gain setting value of the actuator coil 15 in the direction of tracking is made revisable. Then, by optionally setting the switching states of the switches S1-S4, the dispersion in the sensitivity of the actuator is absorbed by setting the gain of the servo control system. Thus, the dispersion in the gain of the servo control system due to the dispersion in the sensitivity of the actuator is reduced.

Title: Interactive diagnostic device
Inventor: MEGURO RIEKO
IPC: G06Q10/04
Filed: 1987-05-30
Abstract: PURPOSE:To attain quick and proper investigation of a cause of an abnormality by offering auxiliary information for the operator to its reply together with the execution of deduction. CONSTITUTION:Since the auxiliary information required to reply a question is outputted as to the questionnaire requiring much sophisticated professional intelligence for the reply in the process of progressing deduction by having interaction with the operator, the skillful operator can confirm its experience and the unskillful operator can easily reply the question. Since the auxiliary information is only outputted, the operator having the sophisticated professional intelligence can reply the question through the interactive device without looking into the information, and no waste of time is caused. Thus, efficient diagnosis is attained independently of the experience of the operator.

Title: Polarization direction rotator
Inventor: KANTEIRARU JIEIN
IPC: G02B27/28
Filed: 1979-10-16
Abstract: PURPOSE: To obtain from input beams output beams having polarization vector rotated by a desired angle and linearly polarized, by properly selecting the coordinates of reflection points, 3 or 4 used, reflection angles, and further, arrangement of reflection faces.  
     CONSTITUTION: Polarization vector Ei of input beams linearly polarized by configuration of 3 reflection points A, B, C or 4 reflection points A, B, C, D is rotated clockwise by 270° or 90°, and output beams polarized in accordance with vector E 3  or E 0  are obtained, respectively. Elliptic polarization does not occur on points A, D, but on each of points B, C it occurs. But since plane ABC intersects plane BCD at right angle, tangent component E 1t  of vector E 1  on point B becomes normal component E 2n  of vector E 2  on point C, and elliptic polarization occurring on points B,  C is canceled by each other, thus, permitting output beams to have polarization  vector rotated by a desired angle and to be linearly polarized.

Filed: 1994-05-23
Abstract: PURPOSE:To effect an elemental analysis of a coating film whose elemental composition is unknown by dispersing soft X rays generated by condensing laser on a target into a line spectrum of each wavelength. CONSTITUTION:Laser plasma soft X rays are generated by condensing laser light from a YAG laser device 1 with a lens 2 and irradiating an iron target 3. The soft X rays pass through a toroidal mirror as a condensing mirror 4 and are dispersed by a spectroscope 6. The dispersed soft X rays are incident on a material 7 to be measured which is formed on a dry plate for soft X rays in soft X-ray detecting means 5. Then, soft X rays which have penetrated the materiel 7 are exposed on the dry plate for them to take photographs of soft X-ray images of the inner structure of the material 7 to be measured. It is a coating film constituted of carbon, nitrogen, oxygen, hydrogen and silicon. The difference in the transmissivities of soft X rays due to different compositions leads to the identification of elements constituting the coating film.

Title: Laser beam scanning optical device
Inventor: NAIKI TOSHIO
IPC: H04N1/04
Filed: 1989-05-26
Abstract: PURPOSE:To eliminate the need to adjust a shift in irradiation position perpendicular to the scanning direction of a laser beam by arranging a cylindrical lens almost at a distance of the focal distance of the cylindrical lens from SOS sensor. CONSTITUTION:The cylindrical lens 13 is arranged on the optical path between a photodetection(SOS) sensor 12 and a deflection surface almost at the distance of the focal distance of the cylindrical lens 13 from the SOS sensor 12 so that its generating line is parallel to the scanning direction. Therefore, even if the laser beam shifts perpendicularly to the scanning direction, the laser beam is refracted through the cylindrical lens 13 toward the optical axis side so as to irradiate the SOS sensor surface, so that the laser beam is securely detected by the SOS sensor 12. Consequently, the laser beam scanning optical device is obtained which eliminates the need to correct an irradiation shift perpendicular to the scanning direction.

Filed: 1984-06-28
Abstract: PURPOSE:To obtain feed air pressure while eliminating inconveninent manual conversion of the feed air pressure, by previously memorizing the optimum feed pressure corresponding to output air pressure to automatically input the feed air pressure corresponding to the set voltage. CONSTITUTION:When an air pressure reference signal is set with a setting section 1, the signal is converted into an analog value with a D/A converter 5 and applied to an electricity-air converter 6 for converting analog electrical signal to an air pressure signal.

On the other hand, a memory 4 memories the optimum feed pressure signal corresponding to the generated air pressure output of the converter 6 beforehand. So, the corresponding optimum feed pressure signal is read out of the memory 4 based on the air pressure set reference signal to be converted 7 to analog from digital and a feed air pressure corresponding to the optimum feed pressure signal is automatically inputted into the converter 6 from a feed pressure converter 8.
