Title: Base plate for screening heat ray and its production
Inventor: OTANI TSUTOMU
IPC: C03C17/30
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a heat ray-screening base plate having a sufficiently low visible light reflectance at an advantageous cost by spraying a transparent high temperature base plate with a coating solution containing a compound organic substance having a Si-O-Sn bond and thereby thermally decomposing the compound organic substance to form a coating film. SOLUTION: This heat ray-screening base plate is obtained by preparing a coating solution of a compound organic substance having a Si-O-Sn bond in a Si/Sn weight ratio of preferably 0.2-2.2 in a solvent, spraying the coating solution on the surface of a transparent high temperature substrate, such as a floated glass plate heated at 500-700 deg.C, by a spray method, and thereby thermally decomposing the coated compound organic substance with the heat of the base plate to form the Si-O-Sn compound oxide coating film. The coating film has an excellent heat ray-screening function and a sufficient visible light reflectance and does thereby not give a glare appearance. For example, a compound organic compound of the formula (Et is ethyl group; Bu is butyl group) is used to form a Si-O-Sn compound oxide coating film having a film thickness of 55 nm and a visible light reflectance of 11.6%.

Patent JP-S61230073-A (JP)
Title: Ferrite sensor
Inventor: SHIRAISHI KATSUMI
IPC: G01V3/08
Filed: 1985-04-04
Abstract: PURPOSE:To insure metal other than a magnetic material against being detected erroneously and to detect the raceway of ferrite by magnitizing the moving ferrite by a DC electromagnet and detecting the ferrite by two magnetic sensors separated by a magnetic shield plate. CONSTITUTION:The ferrite 6 comprising the raceway of an unmanned transportation system is moved from left to right. A DC magnetic field generated from a coil excited by an DC power source 8 or a permanent magnet 2 magnetizes the ferrite 6, and the magnetic field is transmitted to two magnetic sensor composed of a hole element 9. The leaked magnetic field will not enter the magnetic sensor shielded by the magnetic shield plate 10. An operation amplifier 5 amplifies differentially the detection signal of the hole element 9, whereby such detection can be made whether or not the hole element 9 deviates from the center of the raceway of the ferrite 6. Since the metal other than the magnetic material such as Al will not be magnetized, the erroneous detection will not occur.

Title: Knowledge getting editor constitution backup system
Inventor: YAMAGISHI HIROMOTO
IPC: G06Q10/04
Filed: 1988-03-25
Abstract: PURPOSE:To prevent a user of a knowledge getting editor from forgetting input of related knowledge at the time of input of knowledge and to reduce the number of times of operation required fro input to facilitate the input by defining a dependency attribute to a blank at the time of generating a form and interlocking procedures at the time of setting a blank value. CONSTITUTION:A definition 17 of the dependency attribute defines that the value of blank ?d is checked at the time of addition of a value to blank ?b and the value added to blank ?b is used as an argument to start 'declaration addition' procedures in case of the added value which is not included in values of blank ?d. A form analyzing part 7 sets contents of the dependency attribute to a dependency attribute table 16 when the dependency attribute is defined in a form file 2. When a value is added to the blank at the time of execution of procedures, a procedure selecting/executing part 8 retrieves the dependency attribute table 16. If the added value does not exist in a list of values of the dependent blank, dependent procedures are started to add the value of the dependent blank. Thus, addition of variable declaration is interlocked, and forgetting of input at the time of knowledge input is prevented, and the number of times of operation required for the input is reduced.

Abstract: PURPOSE:To reduce the size of a heat exchanger and enhance its heat transfer coefficient by welding corrugated metal plates, forming communication holes at four corners, closing the communication holes alternately, and also for a fixed number of plates and forming a zigzag liquid passage from a top opening on one end to an opening on the lower end. CONSTITUTION:A large number of metal plates having a liquid-like projection 1 at the center and forming through holes at four corners 2a to 2d (2b and 2d are not illustrated herein) are welded, forming clearances 4A and 4B. The through-holes 2a and 2c at the four corners are connected with each other, thereby forming four through- holes 5a to 5d (5a and 5d are not illustrated here). Each one of the through-holes 5a and 5c in both shorter sides is communicated at every other clearance 4A while the remaining communication holes 5b and 5d are communicated with the remaining clearances 4B respectively. Also, each central part of the both through-holes 5a and 5b on one shorter side is covered with a blind plate while pipe joint couplings 6a and 6b are installed the both ends so as to fill in the both ends of both through-holes on the other shorter side. This construction makes it possible to obtain a thermal transfer coefficient equivalent to the doubled length of the metal plate of the heat exchanger.
