Abstract: PURPOSE:To easily manufacture almost perfectly spherical metal particles by keeping neighborhood of a nozzle hole under the specific oxygen concn. of non-oxidizing atmosphere and dripping molten metal to cooling medium from the nozzle hole through the non-oxidizing atmosphere. CONSTITUTION:In a manufacturing apparatus 10 provided with a molten metal vessel 11 for storing molten zinc and a cooling water vessel 12 set below the vessel, the temp. of the molten zinc is kept by a heater 13 installed at outer periphery of the molten metal vessel 11. A combustion burner 15 is arranged at the side part of a nozzle 14 tip on the bottom part of the molten metal vessel 11 and the neighborhood of opening hole of the nozzle 14 tip is kept to the non-oxidizing atmosphere with the reducing flame thereof. In the above apparatus 10, the molten zinc in the molten metal vessel 11 is dripped from the nozzle 14. Then, the molten zinc just before dropping and zinc particles just after dripping, exist in an anti-oxidant atmosphere and the surface oxidation is prevented and are immediately dropped into the cooling water. Therefore, the zinc particles are maintained with a suitable surface tension and cooled and solidified as the well-formed spherical particles.

Title: Adjusting device for fuel injection timing
Inventor: HANDA SHIZUO
IPC: F02D1/16
Filed: 1989-07-20
Abstract: PURPOSE:To improve control force with centrifugal force of a weight increased by providing constitution in such a way as arranging not a hub but the weight in space between a side cover and a driving flange and transmitting rotation of a small cam to a camshaft through a flange pin and a flange. CONSTITUTION:Not a hub but a weight 5 is arranged in a space part surrounded by a side cover 1 and a driving flange 15. While constitution is provided such that rotation of a small cam 4 is transmitted to a camshaft 65 through a flange pin 61 and a flange 62. Thus by providing no hub in the vicinity of the center of the weight 5, an internal radius of the weight 5 can be formed small by the amount of length of a part where the hub is not present. Consequently, the weight 5 can be formed heavier with the weight made possible in a larger diameter than in the past. Accordingly, centrifugal force, which is a large factor of timer control force for showing ability of an adjusting device, of the weight 5 can be large taken.

Title: Production of steel sheet electroplated with ni-zn alloy
Inventor: ATAYA TAKESHI
IPC: C25D21/14
Filed: 1982-10-28
Abstract: PURPOSE:To reduce cost and suppress sludge generation without using a self- fluxing Ni anode in a production of a titled steel sheet using a horizontal electrolytic cell by providing specifically insoluble anode and self-fluxing Zn anode and replenishing an Ni ion with carbonate. CONSTITUTION:An insoluble anode 2 and a self-fluxing Zn anode 1 are disposed apart from each other at a prescribed space so as to face to a steel strip X which is transferred in a horizontal electrolytic cell from the top and bottom sides thereof, and an Ni-Zn alloy is electroplated on the strip X. A Zn ion is supplied thereto from the anode 1 in this stage. The ratio of the anode 1 with respect to the total anode is preferably determined at 1/2. Then, the need for using costly zinc carbonate is eliminated, and the increase in the Zn ion is prevented by using the anode 2 in some part. Since sludge 10 is formed in the gaps between the anodes 1, the anodes are so formed as to form no gaps between the same. Even if the sludge 10 is to be formed, it is formed on the lower side and therefore the fall of the sludge onto the strip X is prevented.

Title: Ion flow recording head
Inventor: KADOWAKI HIROYUKI
IPC: B41J2/415
Filed: 1993-07-29
Abstract: PURPOSE:To improve a recording speed and to obtain a high surface potential by forming an insulating layer on an upper electrode, thereby increasing the ion current density passing an ion releasing hole. CONSTITUTION:This recording head is constituted by forming the insulating layer on the upper electrode 11 of the recording head 10 which is formed with the upper electrode 11 and lower electrode 13 on both surfaces of the insulating layer 12 and is provided with the ion releasing hole 14 through the head. The ion current receives the influence of the ion current deposited on the insulating layer 20 and the charge of the same polarity as the polarity of the ion current. The repulsive force in the ion releasing hole 14 direction acts between the charges and the ion current. Consequently, the ion current of a wide range is guided to the ion releasing hole 14, by which the ion current density passing the inside of the ion releasing hole 14 is increased and the improvement in the recording speed is resulted. Since the high surface potential is obtainable, the high contrast and high image quality are attained.

Abstract: PURPOSE:To prevent an observed part from being burned, to maintain a picture quality satisfactory without generating a blooming and, simultaneously, to confirm the head part of an endoscope from a part outside a body by controlling the peak value and pulse light-emitting time of the pulse light-emitting light quantity of a light source. CONSTITUTION:When an external light observing switch 38 provided on a light source device 3 is turned on, an ON-signal is inputted to a CPU 39, and the CPU 39 outputs a transillumination signal to a motor movement control circuit 31 and a pulse light emission control circuit 41. The pulse light emission control circuit 41 outputs a timing signal based on the output signals of photosensors 30a and 30b to a lamp control circuit 42, the lamp control circuit 42 supplies a lamp current synchronizing to the timing signal to a light source lamp 22, and a pulse light is emitted. The lamp current is increased in the accumulating period of a CCD 34, the light-emitting quantity of the light source lamp 22 is increased, the lamp current is decreased in a reading period, and the light-emitting quantity is decreased. Thus, the peak value of an illuminating light is raised, a transmission light in the illuminating light emitted from the part outside the body into a body cavity can be observed, and moreover, the light quantity of the whole can be suppressed to such a degree that the observed part is not burned.

Title: Original reader
Inventor: TOGASHI MITSUO
IPC: H04N1/46
Filed: 1985-08-28
Abstract: PURPOSE:To identify black or a chromatic color without making the titled reader complicated and large-sized by inserting plural infrared cut-off filters having different spectral characteristics in an optical path between a light source and an image sensor. CONSTITUTION:A picture face of an original 1 is illuminated by a light source 2 emitting light ranging from visual light to infrared rays. The reflected light from the original 1 is condensed on a photodetector face of an image sensor 5 through an infrared cut-off filter 3 and a lens 4. A sensor 5 converts the partial strength of the reflected light from the original 1 into a time series electric signal to read an original image. As the filter 3, two filters 3a, 3b whose spectral characteristics differ are used and they are changed over in matching with the spectral characteristics of the original picture. Thus, the resolution performance is optimized by the reader itself for a color such as a black pencil picture where the reflectance is constant independing of the wavelength and low and identified as a black color and a color having high reflectance at the infrared-ray region has the optimized overall spectral characteristics of the reader and is identified as high contrast by means of the filter.
