Patent JP-S61216142-A (JP)
Title: Optical head
Inventor: TAKETOMI YOSHINAO
IPC: G11B7/135
Filed: 1985-03-20
Abstract: PURPOSE:To produce an erasing light spot having the quick and slow cooling functions from a single semiconductor laser, by putting a light beam converting optical parts and a cylindrical lens into an optical path. CONSTITUTION:An erasing semiconductor laser 29 is set to produce the S polarization to a polarized beam splitter 28. The light emitted from the laser 29 is polarized vertically by the splitter 28 after passing through an erasing collimator lens 35, a light beam converting optical parts 36 and a cylindrical lens 37. This polarized light reaches a disk recording surface 26 via a polarized beam splitter 22, a total reflecting surface 23, a lambda/4 wavelength plate 24 and a stop-down lens 25 and forms an erasing light spot 38. The reflected light returns to the splitter 22 like the record/reproduction light. In such a case, the reflected light is P-polarized and therefore passes through the splitter 22 to reach a record/reproduction semiconductor laser 20. Thus no concentration of light emitting points is produced for the incident light since the optical axis is slightly shifted.

Title: Radiation measuring apparatus
Inventor: KOUNO KEIZOU
IPC: G01N23/22
Filed: 1978-05-12
Abstract: PURPOSE: To prevent statistical errors from changing with measurement values by making the radiations etc. applied to a detector to a fixed quantity through feedback controlling.  
     CONSTITUTION: Radiation exposure from a radiation generator 11 causes the sample 3 to emit radiation or light according to its composition. These are then detected with a detector 5 and the characteristics of the sample 3 are displayed on indicator by way of a does rate meter 7. In this case, the output of the dose rate meter 7 is so controlled that the input to the detector 5 becomes of a fixed quantity by feedback-controlling the device 11 through a feedback circuit 19. Hence, the occurrence of statistical errors corresponding to the measurement values is prevented and accurate measurement is accomplished.

Title: Automatic valve change-over device in steam turbine
Inventor: TSUJI YUKIROU
IPC: F01D19/00
Filed: 1979-05-11
Abstract: PURPOSE: To prevent the output of a power generator from being fluctuated when a valve is changed-over and also shorten the time required to change-over the valve, by setting a target load, on which the valve is changed-over, through a main steam pressure during starting of a turbine and by starting a valve changing control when an actual load reaches the target load.  
     CONSTITUTION: Based on each of the outputs of a pressure detector 8 for the main steam pressure P 1  generated in a boiler 1, a pressure detector 9 for the pressure P 2  at the downstream of a bypass valve 5 and a power detector 10 for the output W 1  of a generator 3, a turbine controller 7 operates degrees of control required for motors 11, 12, and controls the bypass valve 5 and regulator valve 6 respectively. Here, upon changing the valve from the drive by the bypass valve 5 to that by the regulator valve 6, a value detected by the power detector 10 is compared with a target load of the controller 7 and when the thus-obtained difference falls within an acceptable value range, throttling of the valve 6 is started. Any load fluctuation is controlled by governing the bypass valve 5 in such a manner that its deviation becomes zero and, when said operation comes to a change-over point a main steam shut-off valve 4 is fully opened to proceed with a normal control of the regulator valve 6.

Title: Air conditioning controller
Inventor: OYABU YASUNORI
IPC: F24F11/02
Filed: 1993-03-17
Abstract: PURPOSE:To provide effective air conditioning by controlling a diffusing angle and/or diffusing air flow rate of diffusing air from an indoor unit in response to a volume of a detected room. CONSTITUTION:When microcomputers 13, 25 detect that a room temperature becomes a first predetermined temperature difference from a set temperature, they store this time (t1). Heating is advanced, and when the microcomputers 13, 25 detect that the room temperature is raised to a second predetermined temperature difference from the set temperature, they store this time (t2), and obtains a time ¦t2-t1¦ from the first difference of the room temperature to the second difference. The microcomputers 13, 25 compare the time ¦2-t1¦ with a reference time, and decides whether a space to be air conditioned of the room is wide or not. The microcomputers 13, 25 control, if the room is not wide, normal diffusing, but so regulate, when judging that the room is wide, a diffusing angle that the diffused air reaches farther, and also regulates a diffusing air flow rate as required.

Filed: 1984-03-27
Abstract: PURPOSE:To obtain efficiently basic zinc carbonate useful as a source for feeding zinc for galvanizing in a short time by blowing a source for gaseous CO2 into an aqueous slurry of zinc oxide. CONSTITUTION:CO2 or a substance contg. CO2 is blown into an aqueous slurry of ZnO as fine bubbles to obtain basic zinc carbonate [2ZnCO3.3Zn(OH)2.H2O]. At this time, it is preferable that CO2 is blown into water satd. with CO2 while adding ZnO little by little to the water without blowing CO2 into a slurry prepd. by slurrifying a large amount of ZnO particles with water at a stroke. By this method a uniform product is obtd. in a short reaction time with very easy operation control. The cost of drying is slightly increased, but since the product has very high filterability, the total cost is not increased as compared to a conventional method.

Title: High voltage power supply
Inventor: KAI MIKIAKI
IPC: H02M3/07
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a high voltage power supply which can control an output voltage from 0V by providing, to a base of a reference transistor, a potential adjusting circuit which gives a negative voltage corresponding to the voltage difference of collector and base of an output end side of the a differential amplifier in the absolute value of the base potential. SOLUTION: A negative potential corresponding to the voltage difference between collector and base of an output end side transistor Q3 is given to the base of transistor Q4 from the anode side of a zener diode D1 of a potential adjusting circuit 3. The absolute value of this voltage is less then 0.5V and therefore when a base potential. of the reference transistor Q4 is set to about $1V, it becomes almost equal to the base of the output end side transistor Q3 and thereby an output of the transistor Q3 becomes zero. Thereby, the transistor Q2 becomes OFF. As a result, since a DC voltage is not output from the emitter of transistor Q2, the switching transistor Q1 switches zero potential.

Abstract: PURPOSE:To reduce the variation with time of operating conditions by connecting the second heat element whose temperature coefficient is larger than that of the first heat element to a direct heat body cathode which is almost formed into a gate shape  with the ribbon-shaped first heat element and the electron emission area. CONSTITUTION:The direct heat type cathode 5 opposed to the cathode retaining lead body 2 which penetrates into the insulating substrate 1 and is fixed is formed almost into a gate shape with the ribbon-shaped first heat element 3 and the electron emission area 4 and the diameter of the electron emission area 4 is preset to that which is larger than the width of the flat area 6 for the heat element 3. The second heat element 12 has a coil-or ribbon-shape heat-resistant metal whose temperature coefficient is larger than that of the first heat element body 3 below the electron emission area 4 and is electrically connected in series. This reduces the start characteristics to half of the convertional ones and increases the whole resistivity.
