Title: 2wd-4wd switching control device for vehicle
Inventor: KASHIWABARA MASUO
IPC: F16D48/06
Filed: 1991-03-15
Abstract: PURPOSE:To optimize the timing for returning a vehicle to 2WD (2-wheel drive) to 4WD (4-wheel drive). CONSTITUTION:The road surface friction coefficient mu is calculated (steps 1, 2) based on the shaft torque change during the 2WD running, the time T0 until a vehicle is returned to 2WD after it is switched to 4WD is set based on the mucalculated under the 4WD running condition, and a clutch is turned on to switch the vehicle to 4WD (steps 3-7). When the elapsed time T after the vehicle is switched to 4WD exceeds the preset time T0, the clutch is turned off to return the vehicle to 2WD. When the vehicle is to be returned to 2WD after it is switched to 4WD, the switching can be made at the proper timing in response to the road surface state.

Abstract: PURPOSE: To impart natural woodgrain patterns having a variety of changes by coating transparent colored paint on the surface of a substrate having been given woodgrain patterns by embossing, and subjecting to leveling by gravity flow then irradiating ultraviolet rays thereto thereby curing the same.  
     CONSTITUTION: Transparent colored paint 4 which is curved by ultraviolet rays is coated by using a flow coater 5 on a base material 1 having been given embossed patterns 3 of a woodgrain shape by embossing rolls 6. Thence, it is subjected to leveling by gravity flow for a suitable time in a leveling zone 7 to allow the paint in the raised parts 9 to flow down into the recesses 10, whereby the film thickness of the paint on the material 1 is unevened. If rapid drying is performed by irradiating ultraviolet rays in this state in an ultraviolet ray irradiating furnace 8, color tones delicately differ partially in the resultant plate for buildings and the plate has natural finishes of a wide variety of changes. Veneer or plywood is used for the material 1.

Abstract: PURPOSE:To provide a disc displaying character or the like on an information recording layer and the production method of the disc by changing the width of spirally or concentrically formed tracks or bits partially in accordance with the character, pattern, etc. CONSTITUTION:Benzendithiol-nickel complex and nitrocellulose which are coloring matter sensitivity increasing agents are mixed the prescribed quantity of solvent to obtain the undiluted solution of the information recording layer. The information recording layer 4 is formed on a substrate by using said undiluted solution as the material. A smoothing layer 2 consisting of photoresist is formed on the substrate 1. If characters or patterns are drawn on the back of the substrate 1 with ink or the like absorbing light effectively at the formation of guide tracks 9 on the layer 2, the reflected light of exposure beams irradigated from the photoresist side is reduced at a part on which the characters or patterns are drawn as compared to other parts. Therefore, the width of the bits or guide tracks is thinned at the part including ink as compared to other parts as the result of development, and when the characters or the patterns are observed from the back or front side after removing the ink from the back, the characters or the pattern are shown like watermarks.

Title: Improved growing method for continuous thin diamond film
Inventor: KUANNKAI DEIBUITSUDO JIEN
IPC: C23C16/50
Filed: 1994-03-23
Abstract: PURPOSE: To provide an improved method for growing continuous diamond films.  
     CONSTITUTION: In contrast to previous methods, the present inventors have discovered that diamond films can be grown by carbon CVT reactions occurring exclusively in the exothermic region, where the lower temp. (<1,500°C) conditions considerably simplify the equilibrium gas phase chemistry. Under such conditions as a small temp. gradient and short transport distance between a source and a substrate, supersaturation of the gas phase with regard to graphite and diamond does not attain high values enough to induce spontaneous homonucleation of graphite and diamond in the gas phase. With this process, temp. as low as 680°C were found to be sufficient to induce the growth of continuous diamond films free of non-diamond allotropes.

Title: Vacuum deposition device
Inventor: YANAGI KENICHI
IPC: C23C14/56
Filed: 1983-03-29
Abstract: PURPOSE:To prevent the clogging in lifting pipes during operation by a simple method in a device which conducts the molten metal in a melting furnace in the atm. air through the lifting pipes into the evaporation pan in a vacuum deposition vessel by using the plural melting furnaces and providing means for lifting the furnaces to said furnaces. CONSTITUTION:The molten metals 21 in melting furnaces 19, 20 are sucked under vacuum through lifting pipes 17, 18 into the evaporation pan 13 in a vacuum vessel 12 where a material 11 to be plated travels. Said metal is heated by a heater 16 to evaporate and is plated by vacuum deposition on the surface of the steel strip 11. Lifters 22 are operated during this operation to move vertically the furnaces 19. When the furnace 19 is moved upward, the level of the metal 21 in the pan 13 rises as the pressure difference is constant, then the difference in the level in the pan 13 and the level of the metal 21 in the furnace 20 is made larger than the difference in the stationary stage, by which the metal 21 is admitted from the pan 13 into the furnace 20. When the furnace 19 is conversely lowered, the metal 21 moves through the pan 13 to the furnace 19. Stagnation of dross 24 in each part in the pipes 17, 18 is thus obviated and the clogging in the pipes 17, 18 is prevented.

Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To immediately lower an applied voltage if the voltage applied to an element or wire is abnormal and to protect a line by providing a switching means which connects a constant-voltage source to a column wire when the potential of the column wire exceeds a specific potential. SOLUTION: A column wire modulation part 12 receives a luminance- modulated signal 11 and applies a voltage or current pulse corresponding to its value to a panel column wire. A column wire potential detection part 24 consists of a reference voltage generation part and a voltage comparator and compares the potential of a column wire with a reference voltage to open and close a switch 15 according to the comparison result. If the column wire potential exceeds the reference voltage value for some reason, the column wire potential detection part 24 closes the switch 15 arranged between the column wire and constant voltage source 28 to forcibly clip the column wire potential at the reference voltage value.  Even when the column wire potential exceeds the reference voltage value, the potential is forcibly clipped at the reference voltage value, so that a voltage exceeding an element driving voltage will not be applied to a surface conduction type discharging element.

Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To detect presence of a mending tape applied onto a paper accurately by arranging a first light receiving element to receive a light reflected at an angle larger than the incident angle of light from, a light source impinging on an object. SOLUTION: Upon receiving an oscillation output from an oscillation circuit 20, a projection pulse generating circuit 21 generates a projection pulse signal and drives a light source 1. The light source 1 projects a pulsating light and the light reflected on a work is received by two light receiving elements 2a, 2b and converted into electric signals. These electric signals are fed to peak hold circuits 22a, 22b where the peak values are detected and delivered to a decision circuit 24 which then produces a detection signal. More specifically, an element 2a receiving a light reflected at a larger angle than the incident angle of light from a light source impinging on an object captures variation in the quantity of light reflected regularly on a mending tape and then the quantity of received light is compared between the elements 2a, 2b thus detecting the mending tape.
