Title: Formation of channel of ink jet print head
Inventor: ISHIDA NOBUHISA
IPC: B41J2/135
Filed: 1994-06-09
Abstract: PURPOSE:To reduce an effect associated with a displacement, including a change in channel resistance, and to facilitate the bonding of a diaphragm to a head substrate by making a channel pattern which is exposed to light and developed in an ink channel formation process approximately band-shaped. CONSTITUTION:A through hole 20 is formed in a head substrate by exposing to light, developing and etching a nozzle-penetrating hole pattern 20'. In an ink channel formation process, a channel-formed part 30a' is exposed to light. As a result, a flat ink channel which tapers toward a head is formed in a mask provided in the head substrate 10 and a latent image is formed in the form. The head of the flat ink channel overlaps a part of the through hole-formed part. An ink channel 30a is formed by development and etching. Since the head of the flat ink channel overlaps a part of the through hole formed part, the nozzle through hole and the ink channel can be aligned easily.

Title: Nuclear power plant and its operation controlling method
Inventor: SUZUKI TOSHIYUKI
IPC: G21C7/00
Filed: 1991-05-30
Abstract: PURPOSE:To suppress the distortion of output distribution in the inside of a nuclear reactor to the limited level even if abnormality occurs in a water supply cooling system. CONSTITUTION:When abnormality occurs in the water supply cooling system and voids increase and thus the output of a nuclear reactor lowers, a control rod driving circuit 10 works to control insertion and draw of the control rod 6 owing to the difference between the detected level of a neutron flux detector 3 and the set level A so as to make the difference become 0. At that time, when the breakaway continuing time of the sub-cool degree from a normal range surpasses the set time of a timer 31, a signal to lower the level of the set level A is sent to a subtracter 41 and when the output set level at the normal time is 100%, the output set level is lowered to 80% at the time of abnormality of the sub-cool degree. Consequently, output distribution in the inside of the nuclear reactor is not greatly distorted.

Title: Fixing device
Inventor: OGAWA MASAHIKO
IPC: G03G15/20
Filed: 1995-04-28
Abstract: PURPOSE: To reduce overshoot by the methods other than the changes of structure of a fixing roller and material quality by using a hollow core material for forming an oil supply rotor of an oil supply means. CONSTITUTION: An oil supply means is formed by an oil application roller 1, oil pumping rollers 2, 3, and application oil 16. The oil application roller 1 is so constructed that a surface layer 5 where rubber is made to adhere in several layers is provided on the outside of a core bar 4 which is a metallic core material, and the oil pumping roller 2 is formed only by a metallic core material 6. After the flow of an electric current is stopped, the temperature of the inner surface of a fixing roller 7 is lowered, and the surface temperature is raised to cause overshoot. Accordingly, it is better to decrease the heat radiation amount from the fixing roller 7 to the oil roller system.  In order to decrease the above heat ratiation amount, the heat capacity of the oil roller system may be reduced to the utmost, and the heat capacity of the oil roller system can be decreased by making the oil application roller 1 and the oil pumping roller 2 hollow.

Title: Measuring method for flatness of thin plate in plate rolling
Inventor: TASHIRO YASUSHI
IPC: B21B38/02
Filed: 1990-05-17
Abstract: PURPOSE:To obtain flatness more accurately even when a line tensile force is changed by finding elongation percentage by correcting elastic elongation by a tensile force in the length direction of a thin plate, and finding the flatness from the elongation percentage and a mean value. CONSTITUTION:The application of a load in a direction perpendicular to a pass line and the measurement of the deflection hi of the thin plate 2 at that time are applied to the thin plate 2 travelling between rolls 1, 2 extending over several parts in the width direction of the thin plate. When the elongation percentage is found based on the deflection hi and a distance L between the rolls, the elongation percentage epsiloni can be found by correcting the elastic elongation by the tensile force Ti in the length direction of the thin plate 2. The flatness can be obtained from the elongation percentage epsiloni and the mean value -epsiloni. Furthermore, the tensile force Ti in the length direction of the thin plate when the deflection hi is measured and the load is applied is measured to find more accurate flatness, and the deflection hi is converted to a correction deflection Hi approximated to true deflection by conversion equation including the tensile force Ti, and the elongation percentage epsiloni can be found by using the correction deflection Hi.

Filed: 1993-04-30
Abstract: PURPOSE:To provide the television signal transmission method, the television signal transmitter and receiver in which a defect exerted on an existing receiver is relieved in the wide EDTV system. CONSTITUTION:An orthogonal transformation matrix circuit 30 at a transmitter side is used to apply arithmetic operation processing by linear transformation between plural scanning lines of a reinforcement signal separated from an original signal thereby spreading a signal component localized with a large amplitude into a block through the use of orthogonal transformation and suppressing the level and smoothing the distribution. The reinforcement signal subject to transformation processing is synthesized with a video signal of a main screen by a letter box processing circuit 31 and the result is sent. A separator circuit 32 separates the signal comprising the synthesis of the video signal and the reinforcement signal of the main screen into the video signal and the reinforcement signal of the main screen. The separated reinforcement signal is converted into the reinforcement signal before transformation processing by an inverse matrix circuit 33.
