Title: Pretreatment of polycrystal body for observation of polycrystal body by microscope
Inventor: ISHIZUKA HIROSHI
IPC: C23F4/00
Filed: 1994-06-21
Abstract: PURPOSE:To easily observe crystal particle shapes and the distribution state of a non-crystal phase with microscopic observation by polishing the cut surface of a polycrystal body, then subjecting the surface to a reactive etching treatment in a gaseous phase using a specific gas for etching. CONSTITUTION:A sample S formed by cutting a sintered compact of Si3N4 sintered with CoO as a sintering assistant and polishing the cut surface is placed on an electrode 2 in a vessel 1 of an etching device and the inside of the vessel 1 is evacuated to a vacuum by a discharging device 5. Next, a gaseous mixture composed of gaseous fluoride, such as CHF3, and gaseous oxygen is supplied as the etching gas from a gas supply section 4 and high-frequency electric power is impressed between the electrode 2 and a counter electrode 3 by a high-frequency power source, by which the etching gas is converted to plasma. The cut and polished surface of the sintered compact S is thus subjected to the reactive etching treatment using chemical reaction and sputtering in combination. The Si3N3 crystal grains at the cut surface are etched earlier than the non-crystal phase consisting of the sintering assistant of the CoO and a difference in level is generated between both. The crystal grains and the non- crystal phase are thus distinctly discriminated and separately observed when both are observed by the microscope.

Title: Molding method for receptacle of thermoplastic resin pipe
Inventor: TAKASHIMA SHINGO
IPC: B29C57/00
Filed: 1978-12-25
Abstract: PURPOSE:To prevent the occurrence of breakage occurring due to a stress applied to a shoulder  portion, by forming a ring-shaped projection at an internal circumferential surface of a pipe  whereat a shoulder portion of a taper socket will be formed, and by upheaving a portion, whereat  the said projection is formed, at an external circumferential surface of the pipe in reverse to the  projection at the inner circumferential surface. CONSTITUTION:A plastic resin pipe 5 extruded through a space between a die ring 1 and a  mandrel 2 is pulled out by a drawing-out means when it is cooled upon coming in contact with an  outer mold 4. When suspending or reducing a pulling-out speed, or accelerating an extrusion  speed, thermoplastic resin unheaves along a tapered surface 3 of the mandrel, a ring-shaped projection portion 6 having a sharp slope 62 is provided. A portion ranging from a pipe end surface 7  to a rear end of the ring-shaped projection portion 6 is heated to be softened, a taper socket forming mold 10 being inserted thereinto. Said insertion causes the pipe 5 to be enlarged outward at  the projection portion 6. The pipe end so processed is encircled with an outer mold 15, the pipe  end surface 7 being brought into contact with a flange 14 by pushing in the pipe 5 or the mold 10.  After the outer mold 15 is then released, the work is cooled for solidification, the mold 10 being  then removed, whereby a desired pipe is produced.

Abstract: PURPOSE:To prevent the influence of turning-off of a power supply unit in a certain terminal station upon the other terminal stations by providing break circuits and opening circuits between a common bus, a receiver, and a driver if the voltage of the power supply unit is lower than a prescribed value. CONSTITUTION:Break circuits BR1-BRn monitor the voltage of power supply units PU and open circuits between a common bus BUS, receivers R, and drivers DR if this voltage is lower than a prescribed voltage. That is, circuits BR1- BRn consist of voltage monitor parts SV, relays RL, common bus BUS, and relay contacts rl, and the monitor part SV stopts driving the relay RL if the voltage of the power supply unit PU is lower than the prescribed value. Then, the relay contact rl is opened to open circuits between the common bus BUS, the receiver R, and the driver VR, and thus, the influence upon the other terminal stations is prevented even if the power supply unit of one terminal station is turned off.

Title: Feed pressure equalizer of ink jet plotter
Inventor: FURUKAWA TATSUYA
IPC: B41J2/175
Filed: 1978-12-25
Abstract: PURPOSE: To mitigate pulsation from an inlet with air and equalize the fluctuation in discharge pressure, by setting a barrier between the inlet and outlet of liquid with a height lower than the liquid level kept in an air chamber for partially shutting off the liquid flow.  
     CONSTITUTION: As a pump 2 is driven, ink 14 is pressure fed in a head 5 through an accumulator 3 and three-way valve 4 to form ink drops 16 for jet plotting. The discharge pressure of the pump 2 necessarily includes pulsation constituent at this moment. As the pressure enters an air chamber 13 from an inlet 9, the pulsation is mitigated with air in the chamber 13 and flows out from an outlet 10, without being transmitted directly to the outlet 10 because of a barrier 11 shown in the figure. Accordingly the ink 14 flowing through the outlet 10 does not include pulsation, and this equalized pressure transmitted to the head 5 can stabilize injection of the ink and plotting of images.
