Title: Image forming device
Inventor: FUJITA YOSHIO
IPC: G03G15/16
Filed: 1991-10-16
Abstract: PURPOSE:To simplify a mechanism for carrying a sheet from a sheet feeding cassette to a transfer area and to facilitate the separation of the sheet from a photosensitive drum by making the diameter of a transfer roller greater than that of the photosensitive drum and applying a voltage to the transfer roller. CONSTITUTION:The sheet sent from the sheet feeding cassette 42 is electrostatically attracted around the periphery of the roller 71 on and on by the application of a voltage to the transfer roller 71, thereby carrying the sheet to the transfer area C. Therefore, the mechanism for carrying the sheet from a sheet feeding part 4 to the transfer area C can be simplified. Additionally, since the outside diameter D of the transfer roller 71 is greater than the outside diameter (d) of the photosensitive drum 31 by the prescribed ratio, the sheet which has passed through the transfer area C is carried along the transfer roller of the greater outside diameter and the separation of the sheet from the photosensitive drum 31 can be stably carried out without a destaticizing means. A voltage application control means 73 starts the application of a voltage when a detection switch 70 detects the front end of the sheet and stops it after the lapse of a prescribed length of time following the passing of the rear end of the sheet through the transfer area.

Title: Production of superhigh-strength concrete
Inventor: HIRAGA TOMOAKI
IPC: B28C5/46
Filed: 1989-10-17
Abstract: PURPOSE:To obtain superhigh-strength concrete by performing hydration reaction of cement and water while exerting high pressure and adding an admixture such as AE agent and a retardant to cement and water and also kneading this mixture in the low-temp. environment and placing the kneaded substance into a frame mold and thereafter exerting necessary pressure and aging this kneaded substance. CONSTITUTION:Hydration reaction of cement and water is performed while exerting high pressure. An admixture such as an AE agent and a retardant is added to cement and water. Furthermore various materials for concrete preserved at low temp. are kneaded in the low-temp. environment and this kneaded substance is placed into a frame mold and thereafter necessary pressure is exerted and the kneaded substance is aged. Therefore a gap between crystals of cement paste is collapsed by pressure and reduced. The contact area between crystals is made great and bonding force is enhanced. Thereby dispersion of crystal in cement paste is made little and cement paste is made dense. Superhigh-strength concrete is obtained which has compression strength higher than high-strength concrete.

Filed: 1986-11-13
Abstract: PURPOSE:To keep a bearing clearance always constant over all range of engine temperature by lowering the thermal expansion coefficient of a main bearing and a main bearing cap made of light alloy so as to match that of a crank shaft. CONSTITUTION:A main bearing (5), in a body with a cylinder block (1) made of light alloy, is made to contain reinforced fiber having the first thermal expansion coefficient lower than that of a crank shaft (4). Again, a main bearing cap (6) is made to contain the second reinforced fiber having the second thermal expansion coefficient lower than that of the crank shaft (4) and yet higher than the first thermal expansion coefficient said above. Thus, both thermal expansion coefficients of the main bearing (5) and the main bearing cap (6) are made to be lowered, furthermore it is possible that the thermal expansion coefficient of the main bearing (5) is made to be lower than that of the main bearing cap (6) for making said coefficient nearly equal to the thermal expansion coefficient of the crank shaft (4). Then, a bearing clearance can be kept nearly constant over all range of engine temperature. Therefore, noise generation or abrasion in a main bearing (3) can be prevented.

Filed: 1994-11-01
Abstract: PURPOSE: To obtain a range finder which can suppress a distance-measuring error by a method wherein reflected light from an object is photoelectrically converted so as to be output, the distance to the object is operated by using a converted signal so as to be stored in an integrating capacitor and the distance is determined on the basis of the output of the dielectric-absorption-amount detection means of the capacitor and on the basis of a stored distance signal. CONSTITUTION: A background photocurrent in a photocurrent which is output from a photodetector 3 receiving a reflected optical pulse from an object to be distance- measured (i.e., a subject) is removed, and the distance to the subject is operated by a distance arithmetic circuit 5 on the basis of outputs of photocurrent detection circuits 3, 4. An output distance signal is stored in an integrating capacitor 6, and the stored distance signal is converted into a digital signal by a counting part 7. The signal is received so as to drive a light-projection-element drive circuit 9. In addition, a CPU 8 as a control means is provided with a dielectric-absorption-amount detection means 12 and with a storage means 13 used to detect a dielectric absorption amount.  A distance-measuring error due to a dielectric absorption is thereby suppressed without using a capacitor whose dielectric absorption is small and by using a capacitor whose dielectric absorption is large.

SOLUTION: A semiconductor laser 100 is formed so that a laminated structure 120 consisting of a GaN compound semiconductor material is turned into an N-type layer on the side of a sapphire substrate 110 on the sapphire substrate 110. An MgN contact layer 130 consisting of a compound of magnesium with nitrogen is formed on the surface of the P-type layer of this structure part 120. The structure 120 is formed on the substrate 110 and the layer 130, a P side electrode 140 and an N side electrode 150 are formed over the substrate 110. This layer 130 is undoped, but as a nitrogen vapor pressure in the layer 130 is high in this state of the layer 130, the nitrogen vapor pressure is prevented from being bled from an MgN compound by an addition of hydrogen to the layer 130.  Moreover, for improving the characteristics of the laser 100, carbon to act as in acceptor in a II-V compound semiconductor layer is added to the layer 130 and the resistance of the contact layer can be reduced.
