Title: High harmonic oscillation device
Inventor: YAMADA AKITAKA
IPC: H01S3/109
Filed: 1990-05-09
Abstract: PURPOSE:To obtain a compact high harmonic oscillation device which can generate high harmonics efficiently with reduced loss by forming incidence and discharge surfaces which are formed to have a high light transmission property for an n-th harmonic and an optical element which is formed to be highly reflective for a higher m-th harmonic. CONSTITUTION:When an Nd: YAG laser rod 23 is excited, resonance occurs between resonance mirrors 21 and 22 and a resonance light generates a P-wave second harmonic for an incidence surface 31 of an optical element 30 by transmitting through a non-linear crystal element 25. Only a second-harmonic laser light falls from the incidence surface 31 of the prism optical element 30 to a fourth-order laser resonator 40. Resonance occurs between a discharge surface 32 and an output mirror 42 in a fourth-order laser resonator 40, a resonance light is transmitted through a non-linear crystal element 42 and generates a fourth harmonic, and then only the fourth harmonic is transmitted through an output mirror 41 and is output as a fourth harmonic laser light.

Title: Vertical magnetic recording head
Inventor: FURUYA NOBUAKI
IPC: G11B5/23
Filed: 1980-08-25
Abstract: PURPOSE:To enable highdensity reading operation by increasing recording density by joining a thin plate of a high-magnetic-permeability material to one end of an annular magnetic pole. CONSTITUTION:A thin plate 12 of a material with high magnetic permeability is joined to one end surface of an anuular magnetic pole 13, and a magnetic gap 15 is formed between the thin plate 12 and the other end of the magnetic pole 12. On the opposite surface to the surface of the thin plate 12 which comes into contact with the gap 15, a nonmagnetic material layer 14 is arranged. Pieces of magnetic information recorded in a magnetic layer as an upward and a downward magnetized area are read out by the thin plate 12, annular magnetic pole 13 and magnetic gap 15 on the same operation principle with an ordinary ring head. Because of the same structure with the ring head, a 0.2-0.3mum magnetic gap is formed and reading operation with higher recording density than that by a main magnetic pole with 1mum vertical head width is achieved. The recording principle of the main magnetic pole end of a vertical head applies to the magnetic recording by the steep slanting part 19 of magnetic-field intensity distribution 18 formed at the tip 20 of the thin plate 12

Title: Picture recorder
Inventor: FUJII HARUO
IPC: B41J2/43
Filed: 1984-06-08
Abstract: PURPOSE:To avoid the generation of fog, by a method wherein in a toner system picture recorder, the magnetic pole of the same polarity as that of the top magnetic pole of the recording electrode is generated by a magnet at the iron core top of a pulse magnetic field generation measure when recording voltage is applied. CONSTITUTION:In the case of no application of a picture signal to a recording electrode 7, when a recording medium 1 is moved in the direction of A, the force moving toner T in the direction of D is operated. However, it is restricted with the line of magnetic force of a magnet 8 and the toner T does not flow to the downstream from the recording electrode 7. On the other hand, when a picture signal is applied, a pulse current is given to a coil 14 from a pulse magnetic field generator 12 and the magnetic material 13 is excited so that the magnetic pole of the same polarity as that of the magnetic pole generated at the top of the recording electrode 7 is generated at the one side top along the recording electrode 7 of magnetic material 13 with the magnet 8. The head of toner becomes almost perpendicular to the recording medium 1 and a toner image is formed with a picture signal voltage. Then, when the signal voltage disappears, the application of electricity to the coil 14 is stopped and the unnecessary toner is restricted with magnetic field. Thus, the fog is prevented.

Title: Printing head
Inventor: TANIDA TOSHIFUMI
IPC: B41J2/285
Filed: 1983-06-30
Abstract: PURPOSE:To permit the driving of a wire with a great suction force at high speeds by a method in which a plunger is set such that the side end of the plunger in the through hole of a yoke is made close to the other end of the plunger. CONSTITUTION:A plunger 21 is projected to both upside and downside from the upper through hole 19 and set, however, such that the opening edge 20e of the through hole 20 of other yoke 18 is close to the lower edge 21e of the plunger. When an exciting coil 15 is electrically energized, the plunger 21 is sucked into the through hole 20 against a return spring 23 so that the magnetic resistance between the plunger 21 and the yoke 18 is minimized, and printing is made. Since magnetic flux begins to flow in the plunger 21 under the condition that the lower end of the plunger 21 is close to the edge 20e of the through hole of the yoke 18 at the time when the suction of the plunger starts, greater amount of magnetic flux passes in the early period of suction and a great suction force is therefore generated.

Abstract: PURPOSE:To stabilize a density by detecting a reference value whenever process conditions are changed, comparing the density of a standard pattern image with the surface density of a photosensitive body, and correcting the process conditions. CONSTITUTION:In a main control part 400, a circuit carrying out the input/ output control of the phototransistor Tr404 of a P sensor PSN and an LED 403 are composed of a digital analog converter IC1, an operational amplifier IC2, a microprocessor IC3, etc. When the density of toner is detected, top end erasing timing is turned on, and then, a P sensor eraser is turned on, so that a P sensor pattern image is formed in front of an original image on the photosensitive body 121. When the P sensor pattern image reaches a P sensor position, the LED 404 is turned on, the P sensor pattern image is irradiated with light, and reflected light is received by the TR 403 to detect the density. Thus, since the process conditions are corrected, a stable density can be always obtained.

Title: Removal of liquid
Inventor: HENRII ZETSUTO KISUTAA
IPC: B01D53/26
Filed: 1987-05-15
Abstract: An improved process for removing free liquid from a hydrocarbon-rich gas stream is disclosed. Liquid is injected into the gas stream upstream of a chiller and downstream of an acid-gas removal system and any equipment that may affect the water content of the gas stream: compressors, columns, additional knockout drums, heat exchangers or the like. This enhances heat and mass transfer in a manner that both minimizes the formation of small droplets and encourages the coalescence of small droplets in the chiller. As a result, small droplets which would normally pass through a knockout drum and a standard mist eliminator are increased in size, prior to their arrival at a vapor-liquid separator to larger drops which are easily removed by the vapor-liquid separator, and the mist eliminator.
