Title: Ink jet recorder
Inventor: EDOMONDO ERU KAIZAA
IPC: B41J2/01
Filed: 1979-03-28
Abstract: PURPOSE:To facilitate the replenishment of ink while enabling jetting minimal drops for printing by a mechanism wherein a pressure chamber is so arranged as to be invariably communicated ot the inkwell and the outlet orifice through an inlet path and an outlet path each. CONSTITUTION:The inkwell 16 is communicated ot the printing head 18 through a communicating pipe 17. An electronic pulse generator 19 sends a pulse voltage to the printing head by way of a transmission means 21. At this point, receiving one pulse voltage from the generator 19, the printing head 18 jets one discontinuous line of small single ink drops through an orifice 24. The amount of the liquid is controlled by the energy of the pulse voltage applied. The printing head forms a pressure chamber 37 therein and with the application of a positive voltage, a pressure plate 41 is deflected into the pressure chamber so that a pressure is given the ink in the chamber 37 to jet a part thereof on the recording paper 12 through the outlet path 39.

Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a drift excavation device capable of reducing soil pressure resistance around an embedded pipe even during drilling in a debris bed containing much underground water or for a long distance and allowing drilling with low trust. SOLUTION: A dummy pipe 30 is connected between the rear of a rotary excavation machine and an embedded pipe 5. A nozzle 31 is provided in the dummy pipe 30 and connected to first and second liquid force-feed pumps 32, 33 for combined lubricant of a two-liquid hardening type on a ground via check valves 36 with hoses 34, 35. The combined lubricant of a two-liquid hardening type is composed of a first liquid mainly containing special sodium silicate and a second liquid mainly containing a mixture of plural food additives and high purity montmorillonite.  During excavation, the combined lubricant of a two-liquid hardening type is jet from the nozzle 31 to the outer periphery of the dummy pipe 30 and an extra excavated bed 12 between mountains 1, so that excavated sediment formed into mud by mud forming material (bentonite solution or carboxymethyl cellulose) in the extra excavated bed 12 can be hardly separated into water and soil particles. As a result, soil pressure resistance around the embedded pipe 5 can be reduced and the increased of thrust be restricted even during excavation in a debris bed containing much underground water or for a long distance.

Title: Channel type secondary electron multiplying device
Inventor: TAKEUCHI HIROSHI
IPC: H01J43/30
Filed: 1987-02-20
Abstract: PURPOSE:To suppress discharge growth in an inner surface of a secondary electron multiplying device by providing a power source current detecting means for detecting an output current of a high voltage power source which accelerates secondary electrons, and a power source voltage controlling means for controlling an output voltage of the high voltage power source. CONSTITUTION:An output voltage of a high voltage power source 11 is raised by a power source voltage controlling means 15 based on a time constant set-up in advance. Next, an output current of a high voltage power source 11 is monitored by a power source current detecting means 13 so that whether creeping discharge is growing or not is determined by a rise in the output current. Accordingly, in a transient process where the output voltage of the high voltage power source 11 is gradually applied based on the time constant, raising the output voltage of the high voltage power source 11 is stopped when the output current is in excess of its prescribed value, and raising the voltage is again started when the creeping discharge disappears to make the output current the prescribed value or less, and these operations are repeated. Hence, the applied voltage can be made to attain to the prescribed level without destroying the device.

Title: Substrate for magnetic disk medium
Inventor: SATO IKU
IPC: G11B5/738
Filed: 1992-02-25
Abstract: PURPOSE:To simultaneously improve the reliability in a low floating state and the overwriting characteristic to a high-coercive force medium and to enable high-density recording making the surface roughness of the substrate after texturing as small as possible. CONSTITUTION:The substrate surface is subjected to the texturing of 2A<=Ra<=20A as the surface roughness Ra. As a result, the contact of a slider and a recording medium surface is prevented even in low floating of >=0.1mum and the generation of dust which is the direct cause for a head clash is suppressed. The reliability is thus improved. The recording on the highcoercive force medium by the high-frequency signal required for high-density recording is enabled by the attainment of such low floating. The overwriting characteristic to overwriting with the high-frequency signal after writing with the low-frequency signal on the high-coercive force medium is thus improved.

Title: Polymerization of ethylene
Inventor: NISHIOKA HAJIME
IPC: C08F4/00
Filed: 1985-02-28
Abstract: PURPOSE:To (co)polymerize ethylene without hydrogenation loss in such a manner that olefin monomers can be easily removed from the discharged gas because of the absence of nitrogen gas, etc., by conducting the vapor phase (co) polymerization of ethylene in the presence of a light saturated hydrocarbon. CONSTITUTION:In the vapor phase polymerization of ethylene or the vapor phase copolymerization of ethylene with an alpha-olefin in the presence of a polymerization catalyst, not an inert gas conventionally used, such as nitrogen, but a 1-3C saturated hydrocarbon gas (e.g., methane or ethane) is used as a gas for adjusting the pressure in the polymerization system. The gas discharged from the polymerization system contains no inert gas such as nitrogen, so that olefin monomers can be easily recovered from the discharged gas and the recovered olefins can be used as a fuel of a high heating value. In addition, the loss of olefin monomers due to hydrogenation in the case of (co) polymerization in the presence of hydrogen can be prevented or decreased.

Filed: 1990-02-21
Abstract: PURPOSE:To enable formation of a mask of a minute width by a method wherein after a resist film is patterned, an insulating material is applied by a spin-on- glass method so that an insulating film is formed of the insulating material applied in a minute space between resists, and this insulating film is made to be a mask, with the resists removed. CONSTITUTION:A resist film 2 is formed on a semiconductor substrate 1 and a resist pattern is formed by patterning the resist film 2. Next, an insulating material is applied on the surfaces of the substrate and the resist pattern by a spin-on-glass method and hardened by drying and thereby an insulating film 4 is formed. Then, the resist pattern and the insulating film 4 formed on the surface thereof are removed and the insulating film 4 left on the surface of the substrate is shrunk by heating, so that a mask be formed. In other words, the mask is formed by inverting the resist. According to this constitution, the minute mask can be formed, while the insulating film 4 forming the mask hardly exfoliate from the substrate 1 even in a heat treatment of high temperature, since it is baked twice.

Abstract: PURPOSE:To constantly obtain an optimum equalizing and amplifying characteristic for every channel by dynamically controlling the characteristic parameter of an equalizing amplifier according to a phase difference detected by a phase difference detecting means. CONSTITUTION:The channel phase difference detector 15 detects the phase difference between a R line and a T line for every channel from the timing signal of the respective channels on a transmission R line frame from a frame assembling part 13 and a T line frame from a receiving buffer 8 and transfers to the equalizing amplifier 16 as a control signal. The equalizing amplifier 16 is situated between the receiving buffer 8 and an identifier 10, receives a control signal from the channel phase difference detector 15 to receive the T line frame and dynamically change the characteristic parameter of the equalizing amplifier 16 for every timing of the respective channels. As the larger the phase difference fed from the channel phase difference detector 15 grows, the equalizing and amplifying characteristic according to the transmission path of a long distance is obtained.
