Filed: 1993-08-27
Abstract: PURPOSE: To easily sample such resource as underground water at a desired depth by providing a slot with an angle interval around a sampling tube while being separated in an axial direction with a taper. CONSTITUTION: A slot 208 is provided in a longitudinal axial line while being separated with a specific angle interval around a tube 200 at a tube auger part 200 including a flight 202 on an outer surface.

Title: Developing device
Inventor: TASHIRO TSUNEO
IPC: G03G15/08
Filed: 1981-12-26
Abstract: PURPOSE:To prevent dirt of a surface and an edge effect, and to obtain an excellent image having uniform density, by providing a counter electrode on a toner holding roll, applying DC bias between both of them, and superposing AC voltage onto the counter electrode. CONSTITUTION:A counter electrode 8 is provided so as to cover a toner holding roll 1, and between both of them, DC bias voltages Vd1, Vd2 having the same polarity and the same potential are applied from electric power sources 10, 11, and AC voltage Vc is superposed onto Vd2 from electric power source 12. The voltage Vd1 is set lower than the potential Va of an electrostatic latent image, and higher than the potential Vb of other exposing part. Therefore, as for a toner 4 which is between the roll 1 and the electrode 8, AC voltage goes and returns between them, friction charging is quickened, also it becomes like a cloud, and the developing efficiency is elevated. Also, since the potential of the exposed part is lower than that of the roll 1, the toner 4 does not adhere and dirt of the surface is not generated. In this regard, an electrostatic power line of a drum 2 goes toward the roll 1, therefore, the edge effect does not appear, and an excellent image is obtained.

Filed: 1990-08-14
Abstract: PURPOSE:To shorten a warm-up time and to minimize the change in an image density caused by the change in a belt temperature by providing a temperature sensor, comparison means, and heater control means. CONSTITUTION:The heating of a heat roller 34a is started by a heater 35a; the temperature of the roller 34a first satisfies the relationship of Vr>=Vrx; a comparator 40a and an AND circuit 42a reach an L level; consequently a switch 39a is turned off. When the belt temperature reaches a development temperature Tbs, the relationship of Vb>=Vbs is satisfied, and a comparator 41a reaches an L level. In such a manner, after heat-resistant carrying belts 31 and 32 reach the development temperature Tbs, switching on/off the heaters 35a, 35b -, 35f are controlled based on the belt temperature Tbe. Since the belt temperature is directly detected to control the heater 35, the change in the belt temperature can be prevented; the change in the density of a photosensitive material is eliminated and, thus, a satisfactory heat development picture can be obtained.

Title: Asynchronous/synchronous mode switching method for pwm inverter
Inventor: TSUCHIMOTO NAOHIDE
IPC: H02M7/48
Filed: 1985-09-25
Abstract: PURPOSE:To prevent an overvoltage from being generated by switching from asynchronous mode to a synchronous mode of an inverter when a U-shape sinusoidal wave alters from negative to positive, and deciding the switching time point by the gradient of a triangular wave and the phase difference of the U-shape at that time. CONSTITUTION:A triangular wave is compared with a sinusoidal wave in an asynchronous mode program, and a rightward up UD=1 and rightward down UD=0 of the triangular wave are detected. An external clock C (frequency = 1,536 X inverter frequency) is counted to obtain a counted value CN. CN=CN-1,536 is set in case of CN 1,536, and when setting a synchronous mode, it is shifted to a mode switching program. In case of CN>18 and UD=0, it is waited until CN=55 is satisfied, and in case of CN<=18, it is switched to the synchronous mode when CN=18 is satisfied. In case of CN>18, UD=1, it is waited until CN=55 is satisfied, and in case of CN<=18, CN=18, it is switched to the synchronous mode. Thus, the asynchronous mode is shifted to the synchronous mode by displacing from the mode switching signal to pre vent an overvoltage from being generated.

Filed: 1996-08-13
Abstract: PROBLEM TO BE SOLVED: To lessen scattering of dust to the periphery, to increase the bulk specific gravity if a constructed body and to enable use of porcelain earth for a portion to be brought into contact with molten metal by a method wherein the porcelain earth wherein a quick setting agent is mixed together with compressed air is sent by a nozzle piping to a spray nozzle connected to the fire end thereof. SOLUTION: A porcelain earth of unshaped refractory having self-fluidizing properties is sent under pressure to a site of construction by a pressure sending pump 31 and a pressure sending piping. After a quick setting agent is injected into the porcelain earth, the porcelain earth is agitated by a turbulent flow while it passes through a nozzle piping 33, and thereby the agent is dispersed well in the porcelain earth. By mixing necessary water in the parcelain earth beforehand, the distribution of the water in the porcelain earth is made uniform and almost no accompanying air is present around grains in the porcelain earth before compressed air is injected therein, while almost all bubbles caught up at the time of the injection of the compressed air, a porcelain earth carrier, are released from the porcelain earth on the execution of execution of construction by spraying.  As the result, a constructed body of the unshaped refractory of which the porosity is small and the bulk specific gravity large is obtained.

The luminous flux from a light source 3 is irradiated on the central part at the top end of the detector 1 and the scattered light within the specified angle out of the scattered light generated by the particles in the sample is condensed. The change of the scattered light which is condensed is converted to an electric signal by a photoelectric converter 4. The output thereof is conducted to a data processing part 5, by which the particles are analyzed. The result is displayed on a display part 6 and is recorded in a printing part 7. The part 4 feeds only the scattered light 16 to a lens by a plate 11 for blocking the direct light from the light source. The lens images the condensed luminous flux at the center of an aperture plate 13. The scattered light past the plate 13 is diffused using an optical diffusion plate 14 and the diffused light is detected by a photodetector 15. The background light owing to the scattered light except the light scattered by the particles to be measured as well as stray light, etc. is thus removed and the particle analysis is efficiently executed.
