Title: Recorder
Inventor: MIURA KUNIHIKO
IPC: G03G15/047
Filed: 1984-05-07
Abstract: PURPOSE:To prevent generation of a region where a developer does not stick to the surface of a recording medium for a long period on said surface by providing a means for forming an image in the part of the recording medium except the region to be transferred at every recording on a prescribed number of paper. CONSTITUTION:A photosensitive body 301 is recorded with information thereon by a beam and an electrifying means 304 and electrifies uniformly the body 301 to prescribed potential. A transfer means 305 transfers a developer toner to paper. A developing means 307 is a developing device and an exposing means 311 exposes the medium 301. On the other hand, paper feed means 318 is an upper feed roller for taking out each sheet of paper from an upper cassette and a means 327 is a feed roller for manual insertion to be used to convey said paper after the insertion of said paper is confirmed. A line is formed in the region except the region to be transferred on the paper at every recording of a prescribed number of paper and therefore the toner sticks to said region. The generation of the region where the toner does not stick to the surface of the photosensitive body for a long time on said surface is thus prevented.

Title: Protection of superconductive coil
Inventor: IWAMOTO TOSHIO
IPC: H01F6/06
Filed: 1981-06-17
Abstract: PURPOSE:To prevent a superconductive coil from seizure, by transferring energy between the superconductive coil and a metal tube, when the metal tube is provided to reduce current at the super-conductive coil rapidly. CONSTITUTION:When voltage is applied between terminals of a coil 10 in a direction to reduce coil current, the coil current decreases and does the magnetic field the coil produces. At the same time, current flows through a metal tube 11 in a direction to hinder changes of magnetic flux due to a reaction of mutual inductance between the metal tube 11 and the coil 10. The changes in current flowing through the metal tube 11 induce electromotive force to change the current at the coil 10 and reduce the coil current.

Title: Noise prevention means for freezing compressor
Inventor: MUWATARI NERIYUKI
IPC: F04B39/00
Filed: 1978-07-27

Title: Liquid fuel combustion device
Inventor: YAMADA HIROFUMI
IPC: F24D11/02
Filed: 1979-07-24
Abstract: PURPOSE: To prevent tar in evaporated fuel from being heated and sticked to a movable rod by circulating liquid fuel in a fuel supply passage around the movable rod equipped with a valve and other working members and cooling the movable rod with the liquid fuel.  
     CONSTITUTION: By flowing an electric current through a heater 11 and by flowing an electric current through a solenoid 18 after a specified preheating time has passed, a movable rod 6 is moved back thereby supplying liquid fuel to a vaporizer 2,  and heated and vaporized gaseous fuel is blown off to a burner 4 from a nozzle 3  and burned. At this time, the movable rod 6 is heated by the heat from the vaporized fuel, but the movable rod 6 is cooled by liquid fuel flowing through a liquid  chamber 20 around the rear end of the rod and maintained at a comparatively low  temperature, so that a part of vaporized fuel that condensed on the movable rod 6 drops off the movable rod 6 unchanged and sticking of tar residues due to distillation phenomena caused by the heating of the movable rod 6 does not occur. Also, heat conduction to the solenoid 18 is prevented by the cooling of the movable rod 6 and the deterioration of the solenoid 18 due to heat can be prevented.

Title: Memory control system
Inventor: AMAMIYA TAKESHI
IPC: H04N1/00
Filed: 1984-05-10
Abstract: PURPOSE:To use effectively a memory part and to improve the transmission efficiency by providing a detection means to a repeating device to detect that the quantity of data stored in a memory part reaches the 1st and 2nd set limit levels to transmit an information signal to a transmitter according to the detection signal of the 1st detection means and to transmit a transmission request signal to the transmitter according to the detection signal of the 2nd detection means respectively. CONSTITUTION:The picture data is first delivered from a transmitter 1 and stored temporarily to a data memory 5 of a repeating device 13. When the 1st detection part 8a detects the set limit quantity L1, a detection signal is sent to a main control part 14. Then a command is outputted to an informing part 11, and an alarm signal is sent to the transmitter 1 from a line control part 6. Receiving the alarm signal, the transmitter 1 discontinues automatically the transmission and reserves the polling transmission for the rest originals. Then the memory 5 has a margin of storage, and the 2nd detection part 8b detects the set limit quantity L12. Thus a detection signal is sent to the part 14, and a polling reservation control part 9 outputs a polling reservation signal, etc. through a memory 10. While the part 14 performs the automatic dialing to call out the transmitter 1 and outputs a polling request.

Title: Clad precoater
Inventor: ISHIMARU HITOSHI
IPC: B01D61/10
Filed: 1988-04-18
Abstract: PURPOSE:To prevent sticking of fats and oils and org. components to a hollow yarn membrane by constituting the clad precoater of an iron clad generator and a clad injection piping and connecting the clad injection piping to the inlet side of a hollow yarn membrane filter device. CONSTITUTION:An inlet sop valve 5 and an outlet stop valve 9 of a condensate filter device 7 are fully closed and an iron clad injection device 24 is operated to form iron clad. The clad is captured by the hollow yarn membrane in the filter device 7 and the condensate returns to the injection device 24 when the iron clad is injected together with the condensate into an inlet pipe 6 by an injection pump 25. The clad is thus precoated on the filter device 7 and the fat and oil components in the condensate stick to the initially precoated clad and, therefore, the sticking thereof to the pores of the hollow yarn membrane do not arise. The abnormal increase of a differential pressure is, therefore, obviated and further, the clad is removed from the hollow yarn membrane by backwashing water. Since the fat and oil components are simultaneously removed from the membrane, the differential pressure is restored.

Abstract: PURPOSE:To increase the degree of freedoms at the time of operating tables by providing feed nuts to be engaged with feed screws at the lower parts of two tables, and motors for rotating the nuts. CONSTITUTION:Tables 6, 7 are driven motors to supply electronic components solely or integrally with both to a transfer head 3 while moving a working area A, and solely retracted to retraction areas B, C to replace a table unit 8. For example, if any electronic component on the table 7 is in shortage, the table 7 is retracted to the right area C, the table 6 disposed in the area B is moved to the area A, reciprocated in the area A to supply the component, and the unit 8 of the table 7 retracted to the area C is replaced. Thus, the degree of freedoms in the operation of the tables can be enhanced.

Title: Microcapsule particle of colloidal silica and its production
Inventor: OOSAKI ICHIROU
IPC: B01J13/14
Filed: 1982-06-01
Abstract: PURPOSE:To form colloidal silica to a microcapsuled particulate shape which is easy to handle while retaining the high bulkiness thereof by enclosing the circumference of said silica with a polymer. CONSTITUTION:Extremely fine colloidal silica has extremely high bulky structure and is vulnerable to scattering up in air during handling. A mixture of the colloidal silica and toluene, terephthalic acid dichloride is added under stirring into an aq. soln. consisting of PVA, water and sodium hydrogencarbonate and is dispersed therein whereby oil drops are formed in order to prevent the above- mentioned scattering up. This stirring is continued under dropwise addition of an aq. 10% hexamethylene diamine soln. to prepare a slurry, whereafter the slurry is filtered and washed and the remaining PVA is washed. The mixture is dried whereby 500-50mu microcapsules which have the polyamide walls contg. the colloidal silica and are easy to handle are obtained. When the microcapsules are sheared, the colloidal silica is easily obtained from the inside.
