Title: Electrophotographic copier
Inventor: SAWAOKA EIJI
IPC: G03G21/00
Filed: 1980-07-14
Abstract: PURPOSE: To enable sufficient cleaning effect to be obtained by controlling cleaning operation while keeping a rotary bristle brush revolve by the movement of the cleaning means of a copying machine which performs one time of copying by rotating a photosensitive drum twice.  
     CONSTITUTION: The electronphotographic copier is supplied with the copying paper A via a copying paper supply path 26. Reversal visible images are transferred on the copying paper A by the action of a device 8 serving also as charging so that the normal images are copied on the copying paper A. Thence, the copying paper A is stripped by a stripper 24 and is guided by a copying paper transfer-out path 28 whereby it is transferred out to a tray 27. During this time, a drum 4 starts the operation of the second turn and performs erasing of residual charge, attraction of the residual toner to the magnetic brush side, etc. and in the mean time it undergoes cleaning action while a rotary bristle brush 22 is held rotated. These eliminate cleaning in the state of revolution insufficiency right after the starting and enable sufficient cleaning effect to be obtained.

Title: Production of vinyl chloride polymer
Inventor: OKUNO YOSHITAKA
IPC: C08F6/06
Filed: 1980-07-14
Abstract: PURPOSE: To control foaming on the surface of a polymerization mixture, by recirculating a slurry mixture in the polymerization system through a recirculation pipe to the upper portion inside the reactor during the latter half of the polymerization period, and spraying the slurry from spray nozzles over the surface of the polymerization mixture, in polymerizing a vinyl chloride type monomer in an aqueous medium.  
     CONSTITUTION: Into a polymerization vessel are charged a vinyl chloride-based monomer (mixture), a polymerization initiator, an aqueous medium and a dispersing aid, to start the polymerization. During the polymerization reaction, the slurry mixture of the polymerization system, after the conversion has reached 50%, is circulated continuously or intermittently through a recirculation pipe to the upper portion inside the reactor, and the slurry mixture is sprayed from at least one nozzle provided on the upper portion over the surface of the polymerization mixture, to continue the polymerization and finally obtain a vinyl chloide (co)polymer. The time of recovery can be shortened by performing the circulation and spraying of the slurry mixture also during the unreacted monomer recovery operation subsequent to the polymerization reaction.  
     EFFECT: No scale forms, and products with less fish eyes can be obtained.

Title: Constant speed running device for car
Inventor: MORI AKIRA
IPC: B60K31/00
Filed: 1982-06-07
Abstract: PURPOSE:To prevent a rear-end collision with a preceding car at its sudden deceleration, by providing a circuit detecting the distance between two cars going in the same direction and a circuit releasing the constant speed running operation when the distance is a prescribed value or below, in the device running a car in a constant speed for a reference speed. CONSTITUTION:When a distance with the preceding car is sufficient, since a discrimination circuit 70 gives no output, a normally closed relay 80 is turned on. Since the device is in the constant speed running, then brake, clutch, and OFF switches 32-34 are all turned on. If the preceding car 60 decelerates suddenly, the distance with the car detected at a circuit 50 detecting the distance between cars going in the same direction is shorter than a suitable value and the relay 80 is turned off, then a control circuit 20 releases the constant speed running for applying engine brake, allowing to prevent the rear-end collision.

Abstract: PURPOSE: To drill a vertical well with a large diameter simply by a method wherein, in drilling a deep aeration tank for treating water, a vertical well with a small diameter and a desired depth is firstly drilled by an impact drilling body and thereafter, the drilling is carried out by replacing a leading end cylindrical body of the same drilling body with one having a larger diameter.  
     CONSTITUTION: An impact drilling body 14A equipped with the first cylindrical portion 14b mounted to a leading end of a cylinder 14a having a diameter larger than that of said cylinder 14a is repeatedly dropped to drill a vertical well with a diameter smaller than that of a disired diameter. Subsequently, the impact drilling body 14A is drown upwardly from the vertical well and a drilled substance removing body 15 is entered into the vertical well and, by carrying out the dropping motion thereof, drilled soil, sands or stones accumulated in a well bottom are exhausted out of the vertical well. This operation is repeatedly carried out to drill a vertical well with a small diameter and an objective depth of 1,000m or more. Subsequently, the second cylindrical portion 14c with a diameter larger than that of the first cylindrical portion 14b is welded to the leading end of the impact drilling body 14A and is used as an impact drilling body 14B for enlarging a diameter to enlarge the diameter to form a well G with a further larger diameter. Said operation is repeated until a well with an objective inner diameter in attained, and accordingly, a vertical well for a deep aeration tank in the ground within a short time by a simple installation is obtained.
