Title: Ink jet recording apparatus
Inventor: TAKEMOTO KIYOHIKO
IPC: B41M5/00
Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To prevent that printing is continued though one soln. is exhausted by setting the housing amt. of a first liquid and that of an ink compsn. so that the ink compsn. is precedingly exhausted. SOLUTION: An ink compsn. and a first liquid containing a polyvalent metal salt are housed in an ink tank 2 to be supplied to a recording head 1 through a tube 3. The ink tank 2 is internally partitioned to provide an ink compsn. chamber and a first liquid chamber and, in consideration of the respective consumption amts. of the ink compsn. and the first liquid, the amts. of the ink compsn. and the first liquid are determined so that the ink compsn. is precedingly exhausted as compared with the first liquid. Since the ink compsn. is precedingly exhausted, it is known that a recording method printing two liquids becomes impossible by such a clear state that color printing is not performed and recording by two liquids can be always performed.

Title: Simulation of see-through double image for plate glass
Inventor: MUROMACHI TAKASHI
IPC: G01M11/00
Filed: 1988-07-16
Abstract: PURPOSE:To enable quick calculation of the degree of separation of a double image over the entire surface of glass by obtaining a three-dimensional shape model of a plate glass expressed in a curved patch form from a given glass shape data. CONSTITUTION:A geometrical three-dimensional shape model 2 of a glass curve is generated from a design plan of a window glass 1 and a design data with a shape modeller using a shape modelling method by a CPU. Then, a light beam R0 directing to an eye point EP of an operator from a light source L outside a vehicle is assumed by a double image simulator to track an optical path following laws of reflection and refraction and finally, a parallax angle betais calculated between branch light beams R1 and R2 as cause of a double image. Then, the degree of separation of the double image corresponding to the parallax angle beta calculated at numerous points on the window glass 1 is displayed visibly on a display device by displaying and printing in the form of an intensity distribution chart along a glass surface. This allows a designer to identify the state and degree of the generation of the double image viewing the intensity distribution chart to judge whether a standard is satisfied or not.

Abstract: PURPOSE:To prevent dielectric breakdown due to the occurrence of spark by arranging two or more kinds of contact different in resistivity on a base and bringing contacts into contact with a photosensitive body in the order from the contact having the highest resistivity to raise stepwise the surface potential of the photosensitive body. CONSTITUTION:High-resistance conductive contacts 11 and low-resistance conductive contacts 12 are blocked into a brush on a conductive base 10 consisting of aluminum or the like slightly apart from each other.

Filed: 1982-10-13
Abstract: PURPOSE:To eliminate an oil seal and enable a damping force to be effectively displayed only in severe vibration region by sealing an open end of a cylinder tube with a soft diaphragm and providing an orifice and a valve mechanism in a piston defining a pressure chamber and an oil reservoir chamber in said tube. CONSTITUTION:When a power unit (not shown) mounted on a mounting portion 9 of an end of a piston rod 7 weakly vibrates, a valve body 5c provided in a piston 2 is opened since pressure in a pressure chamber A of a cylinder chamber 1 does not exceed a predetermined value. Thus, oil flows freely through an orifice 3 and a communicating path 4 not to produce any damping force. On the other hand, in the hard vibration of the power unit, pressure in the pressure chamber A exceeds a set value to close the valve body 5c. Thus, oil flowing through the pressure chamber A and an oil reservoir chamber B passes through only the orifice 3 to increase flow resistance and produce the damping force. Thus, the transmission of weak vibration to a car body and the variation of pressure in the oil reservoir chamber B are prevented by a soft diaphragm 6.

Title: Controlling method of induction motor
Inventor: FUJIOKA YOSHIMOTO
IPC: H02P27/04
Filed: 1982-10-12
Abstract: PURPOSE:To improve the responsiveness of an induction motor at a light load time by controlling a vector when the excitation is weak and weakening controlling the vector when the excitation is strong. CONSTITUTION:When an error pulse number ERP generated for the prescribed period is the set value ERP1 or higher, a processor 112a generates the primary current having an amplitude 11W, and generates the primary current amplitude 11W based on the vector control when the number ERP is the value ERP1 set empirically in advance or lower. Since the exciting current is forcibly controlled to become equal to the value I0min of the minimum limit considering the responsiveness even if the exciting current becomes resultantly excessively small from the result that the speed deviation becomes the prescribed value or smaller in a weakening field control, the responsive characteristics at the light load time so that the speed deviation becomes small can be improved.
