Title: Screw type waste plastic grinding and compacting device
Inventor: TAGUCHI KAZUHIRO
IPC: B29B15/00
Filed: 1985-11-18
Abstract: PURPOSE:To prevent the over-heating of waste at the composition section of a device from occurring owing to the excessive charging of waste or the charging of bulky waste by a method wherein an annular curvature groove is provided on the large diameter side of the tapered part of a screw so as to make the transfer passage sectional area between said tapered part and the conical part of a casing, which surrounds the screw, larger than the transfer passage sectional area between the screw shaft of the screw and the feeder part of the casing. CONSTITUTION:An annular curvature groove 29a is provided on the large diameter side of a tapered part 29, which integrally connects the screw shaft 7 with the degassing bar 8 of a screw 25. As shown at the hatched part of the curve A in the attached figure, the groove 29a is formed so as to make the transfer passage sectional area between the tapered part and the conical part 3 of a casing 4, which surrounds the screw 25, larger than the transfer passage sectional area between the screw shaft 7 of the screw and the feeder part 1 of the casing. Consequently, the density of plastic wastes, which is gradually increased to the direction of its transfer, is once decreased at the groove 29a part a shown at the hatched part of the curve B in the attached figure. Thus, even if plastic wastes 6 are charged excessively or bulky waste is charged, the generation of frictional heat is suppressed and the overheating of the wastes at the compaction section can be prevented from occurring.

Title: Reverse rotation driving mechanism
Inventor: ASO HIDEO
IPC: F16H3/34
Filed: 1985-11-18
Abstract: PURPOSE:To simplify the structure and make working easy, by forming non- teeth portions on respective substantially halves of the circumferences of internal and external teeth meshing with a transmission wheel. CONSTITUTION:An outer projection 81 is formed on its outer circumference with a tooth profile 81a. The outer projection 81 is further formed on substantially half its inner circumference with an internal teeth 81b for reverse rotation, and on the remaining half with a non-teeth portion 81c. On the other hand, an inner projection 82 is formed on substantially half its outer circumference with an external teeth 82b for reverse rotation in opposed relation to the non- teeth portion 81c, and on the remaining half with a non-teeth portion 82c. A transmission wheel 9a is interposed between the outer projection 81 and the inner projection 82. With this arrangement, the transmission wheel 9a is alternately meshed with the internal teeth 81b or the external teeth 82b, thereby reversing the rotational direction of the transmission wheel. Thus, the structure may be simplified and the working may be made easy.

Title: Information accumulation type centralized supervisor
Inventor: NAGANO MASAAKI
IPC: H04Q9/00
Filed: 1984-12-07
Abstract: PURPOSE:To make line wire connection unnecessary even in case when the number of monitor items has increased, and to decrease the construction work quantity by reading a state change from plural devices to be supervised and analyzing it, accumulating its data in a storage device, processing it, and outputting the supervisory information. CONSTITUTION:When a state change from a device to be monitored 1 is given to a state change detecting part 2, if the state is changed from a usual state, the state change detecting part 2 sends it out as state change information 3 to a state change sending-out part 4. The state change sending-out part 4 sends out the stage change information 3 as a formatted state change information data 10, to a common signal line 5 under the control of a common signal line control part 6. Also, the control part 6 accumulates the state change information data from plural state change detecting parts 4 prepared in accordance with the number of monitor items in an external storage device 7 through a common signal line 5. Subsequently, this accumulated data 10 is informed to a state change processing part 8, edited so that an attendant can understand it, and outputted as supervisory information 9. Accordingly, even in case when the number of supervisory items has increased, it suffices to only increase the capacity of the storage device 7.

Abstract: PURPOSE:To enhance efficiency in car storing by providing plural sets of correcting rollers exposed to the upper face of a rotating stand and arranged parallel to the center line of the rotating stand, and providing a sensor for detecting cars, and controlling rotation of each correcting roller. CONSTITUTION:When front wheels A, A' are driven onto a first correcting roller 40 a sensor 70 detects the center point P1 between the front wheels A, A'. Then a driving signal is transmitted from a control circuit 80 to a driving portion 60 and all of rollers 41, 42... are rotated and the center point P1 is made to agree with a center line L1 so that the roller 40 is stopped. When the front wheels A, A' are driven onto a second correcting roller 50 the center point P1 is made to agree with the center line L1 by the same operation. When the roller 40 is driven onto rear wheels B, B' the rollers 41, 42... are rotated by the same process as the front wheels A, A' and a center point P2 is made to agree with the center line L1. A car is thus driven onto a rotating table device with accuracy.

IPC: G03F7/20
Filed: 1994-09-28
Abstract: PURPOSE: To make the temperature of a sample holder whose temperature has slightly changed due to, e.g. adiabatic expansion to reach a desired value in a short time and with high accuracy. CONSTITUTION: The body 13A of a sample holder 13 is made of highly resistant conductive material, and this body 13 is provided with electrodes 15A, 15B, 16A, and 16B, and a current is mode to flow to into the body 13 so as to generate heat within the body 13.

Title: Laser recorder
Inventor: KANEKO YOSHIO
IPC: B41J2/44
Filed: 1987-10-14
Abstract: PURPOSE:To attain recording and printing with uniform dot diameter entirely by using a pulse signal in response to the scanning position so as to modulate a laser beam by a picture signal. CONSTITUTION:A scanning position discrimination means 23 detecting the scanning position of a laser beam on a photosensitive body 7 and outputting a scanning position signal, a pulse width control means 24 outputting a pulse signal having an optional pulse width based on the scanning position signal, and a control means 27 using a pulse signal in response to the scanning position so as to modulate the laser beam by the picture signal are provided. Thus, the modulation of the laser beam is controlled by the pulse width in response to the scanning position of the laser beam to turn on/off the beam, then even if the dispersion in the beam spot diameter takes place depending on the difference in the scanning position, the dispersion is cancelled by the lighting pulse width control thereby making the dot diameter formed on the photosensitive body nearly identical even at any scanning position.
