Title: Gradation image preprocessor
Inventor: SUZUKI MOTOYUKI
IPC: G06T5/00
Filed: 1988-08-30
Abstract: PURPOSE:To speedily execute the preprocessing of gradation image data at a real time and to release a request to an illumination condition or an optical system by executing arithmetic processing to referring data corresponding to the respective partial areas of an input image space, and gradation input image data. CONSTITUTION:The referring data to be used for the arithmetic processing of the respective partial spaces are housed to a referring memory 1 by a CPU2 in correspondence to the illumination condition or the type and position of work. The CPU2 impresses a control signal to a selector 5 and switches the address information source of the memory 1 to a controller 3. The controller 3 detects a vertical synchronizing signal 9 out of a video signal inputted to an input terminal 4, and starts the generation of an address 10 to be inputted to the memory 1 and the generation of a rack clock to be inputted to a catching device 6 from the rear edge of the signal 9. The referring data to be read from the memory 1 by the address 10 are caught to the device 6 by the clock 11. The output of the device 6 is inputted through a D/A converter 7 to an arithmetic unit 8 and the arithmetic processing is executed to the referring data and video signal. Then, an arithmetic result is outputted.

Title: Protective water-repellent agent for automotive coating film
Inventor: HIDAKA RYUTARO
IPC: C09D127/18
Filed: 1992-07-06
Abstract: PURPOSE:To obtain an agent which protects the appearance of a coating film of an automobile from natural staining or degradation by dissolving or swelling polytetrafluoroethylene in a solvent. CONSTITUTION:This agent is obtd. by dissolving or swelling polytetrafluoroethylene in a solvent in a concn. of 0.1-20wt.%. Polytetrafluoroethylene, having a low surface tension, imparts water repellency, lubricity, capability of preventing stickiness, and releasability to a coated surface and improves the stain resistance of a coating film. A concn. of polytetrafluoroethylene lower than 0.1wt.% gives a nonuniform film inferior in water repellency; one higher than 20wt.% makes the coating work and finishing difficult though no problem occurs in protective and water-repellent effects. A volatile, completely fluorinated fluorocarbon represented by the formula is the most derivable as the solvent.

Title: Wall temperature monitor for steam turbine
Inventor: SUMIHIRO ATSUO
IPC: F01D19/00
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To eliminate speed keeping within a dangerous speed range during increase in engine speed in a wall temperature monitor for a steam turbine. SOLUTION: A steam turbine wall temperature monitor has functions to detect a temperature difference between steam turbine casing surface temperature T2 and casing middle temperature T3 and to compare the detected value with a previously decided temperature limit value and to restrict the number N of revolutions of a steam turbine and its output W when the detected value exceeds the limit value. Since operation restriction caused by the wall temperature monitor is not carried out within a dangerous speed range Nc during increase in engine speed, the damage of the turbine due to the enlargment of vibration of the turbine can be avoided within the dangerous speed range Nc.

Title: Double wall cooling structure of turbine blade
Inventor: YAMAWAKI HIDEMICHI
IPC: F01D5/18
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To provide a double wall cooling structure of a turbine blade, capable of greatly improving cooling efficiency of the turbine blade and reducing the thickness of the turbine blade. SOLUTION: In this structure, a blade outer wall 1 which has a film cooling hole 3 and a blade inner wall 2 which has impingement holes 4 are arranged to have a gap S between them, and these walls are connected to each other through a plurality of pins 5. The surface of the many pins 5 and that of the blade inner wall 2 connected thereto contribute as the heating area from which heat is released. By reducing the gap S between the blade outer wall 1 and the blade inner wall 2, the extension of a high-speed cooling air flow which is jetted from the impingement holes 4 (see arrow A) is restrained by the pins 5 and the high-speed cooling air impinges on an outer surface 2a of the blade inner wall 2 to improve the heat transmission.  In addition to the blade outer wall 1, the blade inner wall 2 connected thereto through the many pins 5 composes a strength member, so that the wall thickness D of the blade outer wall 1 can be reduced. The decrease in the thickness D and the gap S contributes to making the blade thickness C thin.

IPC: H04M3/22
Filed: 1983-11-22
Abstract: PURPOSE:To close an applicable subscriber without requiring special processing by permitting a subscriber ON/OFF HOOK detection circuit to monitor a calling power source and converting a circuit into OFF-HOOK state and informing of it to an exchange in an electronic exchanging device. CONSTITUTION:A reference voltage created by voltage/dividing a calling power source 6 by resistors 9a and 9b is supplied to the (-) input terminal of a voltage comparator 7. Since the calling current is not flowing during ON-HOOK, the (+) input terminal voltage of the voltage comparator 7 is an earth potential. The output of the comparator 7 becomes a low level and a signal during the ON- HOOK is outputted to the subscriber scanning device via an IC gate 10. When the subscriber telephone 1 is made OFF-HOOK, the calling current flows to an earth, resistor 3, current supply circuit 4, terminal 2b, subscriber telephone 1, terminal 2a, said circuit 4, resistor 5 and a calling power source 6 in this order. The potential of the (+) input terminal of the comparator 7 becomes about 40% of voltage of the power source 6, the output becomes at a high level, then the output of the gate 10 becomes at a low level, and is outputted to the subscriber scanning device as OFF-HOOK information.

Abstract: PURPOSE:To accurately judge abnormality by judging abnormality by the comparison of the judging curve of the concn. of carbon dioxide due to the change with the elapse of time from the insulating oil replacing day or operation start day of a transformer with that of carbon dioxide of a judging day. CONSTITUTION:Sequencer units 21 - 2n collect CO2 gas concn. data analyzed by the gas-in-oil analysers 11 - 1n mounted on transformers F1 - Fn to transmit the same to a computer 4. The gas concn. data is periodically collected in a unit of a day or a month and collated with a CO2 gas concn. judging curve to judge the presence of abnormality. For example, when concn. is lower than a requiring care curve, normality is judged and, when concn. is higher than the requiring care curve, it is judged that a care is required. As mentioned above, by adding the elapse time from the replacing time of oil to a judging element even in the same measured value, accurate judgement can be performed.
