Title: Wavelength controller for laser
Inventor: WAKABAYASHI OSAMU
IPC: H01S3/00
Filed: 1989-05-22
Abstract: PURPOSE:To accurately control an oscillating wavelength for a long period of time by controlling the selection wavelength of a wavelength selecting element based on the detection output of a first wavelength detecting means to roughly regulate the wavelength of an output laser light, and finely regulating it based on the detection output of second wavelength detecting means. CONSTITUTION:When the output wavelength of a laser is largely varied from a predetermined set wavelength as compared with the resolution of a diffraction grating type spectroscope 44, a wavelength controller 45 controls the wavelength based on the output of the spectroscope 44, and when it is varied to be smaller than the resolution of the spectroscope 44, the wavelength is controlled based on the output of a monitoring etalon 43. That is, the wavelength is controlled by using the output of the diffraction grating type spectroscope having a wide detecting band for the large movement of the wavelength, and the wavelength is controlled by using the output of the etalon having a high detecting accuracy for the small movement. Thus, even if an output laser light is varied in wavelength of certain large degree, the wavelength of a laser light can be accurately stably controlled for a long period of time.

IPC: G05D7/06
Filed: 1984-06-22
Abstract: PURPOSE:To detect an abnormal place in process in its early stage by automatically deciding measured values of opening of a control valve and a flow. CONSTITUTION:An opening (x) of a control valve and a flow (y) make one set of measured value, and several or more sets of measured values are sampled to previously put the relationship between flow and opening of the control valve into a numerical formula. It is preferable to sample measured values of opening of the control valve and flow in such a manner that a difference between a measured value of flow (x) for staged increase and decrease of opening (y) of the control valve and the previous sampled value of flow is 1-2% of the maximum flow of an outflow control measuring device. Hereafter, whether the value of opening (y) of the control value is within + or -5% of the calculated value is calculated every fixed time according to a program of sequence control. The program is adapted to send a warning on judging that abnormality is caused in process or control system.

Title: Method for operating hollow yarn membrane filter
Inventor: YAMADA KAZUYA
IPC: B01D63/02
Filed: 1987-05-26
Abstract: PURPOSE:To obviate the deterioration in the back washing effect even after the filtration and back washing are repeated by keeping the flow velocity of a liq. permeating through a hollow yarn membrane from the inside to the outside in back washing at more than a specified value throughout each back washing state. CONSTITUTION:In the back washing stage of the hollow yarn membrane filter wherein a raw liq. permeates through the membrane from the outside to the inside, the pressure of the compressed air to be supplied into the hollow yarn membrane filter 1 from a compressed air supply pipeline 35 for back washing is progressively increased along with an increase in the differential pressure in each cycle to control the flow velocity of the liq. permeating through the hollow yarn membrane from the inside to the outside to more than a specified value. By this method, the fine particles collected on the surface of the hollow yarn membrane after filtration are removed to the same extent in each cycle, and the efficiency in back washing is not deteriorated.

Title: Fluid pressure pump
Inventor: NIIYAMA TETSUO
IPC: F04C14/00
Filed: 1980-09-16
Abstract: PURPOSE: To reduce pressure oil pulsation and noise by fixing each gear, fitted on the driving shaft of a gear pump having N number of multi-stages, with 360/N° of phase difference, respectively.  
     CONSTITUTION: Driving gears 7 and 10 as well as drive gears 9 and 12 are rotated by a rotating driving shaft 6, and the oil, flowed into a housing 3 from suction ports 1a and 2a, is delivered from delivery ports 1b and 2b after pressurized while circulating the outer circumferences of the gears. The oil, being delivered as much quantity as the number of teeth per revolution of the gear, generates the same cycle of pulsations. The delivered oil from No.1 chamber generates a pulsation A and the delivered oil from the No.2 chamber generates a pulsation B. However, because of a half pitch phase difference between the driving gears 7 and 10, the pulsations A and B are generatd with a half cycle difference. Furthermore, because the delivered oil is mixed at a common delivery port 15, both the pulsations A and B are combined and compesnated each other to produce a constant pressure C, resulting in the noise reduction caused by the pulsations.
