Title: Method of producing ggg single crystal
Inventor: ENDOU SHIGEO
IPC: C30B29/28
Filed: 1981-04-17
Abstract: PURPOSE: The content of oxygen gas in the nitrogen gas atmosphere is made different between the first half and the latter half in the growth of GGG single crystal to inhibit the contamination with Ir inclusion and increase the length of good-quality crystal.  
     CONSTITUTION: In the production of GGG single crystal by the chokralsky method, the oxygen gas content in the nitrogen gas atmosphere is adjusted to 0.5W3vol% at the first half of the crystal bowl lifting including the heating before the raw material melt down. Then, the content is increased by 1.2W1.5 times that in the first half at the latter half. Thus, the contamination with Ir inclusion is prohibited by controlling the atmosphere to produce GGG single crystal with good-quality crystal length increased.

Title: Ship-bottom antifouling paint for reducing frictional resistance
Inventor: HIROTA NOBUYOSHI
IPC: C09D5/08
Filed: 1982-04-07
Abstract: PURPOSE:The titled paint that is obtained by adding a high water-absorption resin to a paint composition, thus preventing ship bottoms from fouling with marine lives to reduce the frictional resistance in water and keeping the antifouling effect without dissolution into water for a long time with high sailing economy. CONSTITUTION:A high water-absorption resin such as carboxymethylcellulose capable of absorbing water more than 100 times the own weight is added to a paint composition by 0.1-10wt%, preferably 0.5-5wt% based on the total weight of the paint composition to give the objective paint. EFFECT:When the roughness of the coated surface is made small at the beginning, the effect on the frictional resistance is markedly improved, therefore, air-spraying or airless spraying is preferred for coating.

Title: Sequence monitoring device for question-and-answer type bus
Inventor: SUZAKU JIROU
IPC: G06F13/42
Filed: 1980-05-02
Abstract: PURPOSE:To obtain a question-and-answer type bus system of high reliability by monitoring the synchronizing signals playing the role of question and answer in a sequence monitoring device of a question-and-answer type with an up-down counter thereby detecting the disturbance in the question-and-answer sequence. CONSTITUTION:Since an up-down counter 22 takes no more than either +1 or 0 at the normal time when a slave synchronizing signal SSYC11 is inputted after a master synchronizing signal MSYC10, a flop-flop 31 is not set. Since the up-down counter 22 takes +2 or -1 at the anomalous time when either of MSYC10 or SSYC11 is inputted continuously, the flip-flop 31 is also set to output an anomalous detection signal SQCK. At the anomalous time when MSYC10 and SSYC11 superpose, an AND circuit 28 goes on to set the flip-flop 31, thereby outputting the anormalous detection signal SQCK. Hence, the abnormality of the synchronizing signals is detected simply by adding the simple circuits, and therefore the question-and- answer type bus system of high reliability is obtained.

Title: Glued laminated bamboo and laminate material using it
Inventor: YOSHIKAWA YOSHIHIKO
IPC: B27M3/00
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To provide glued laminated bamboo material which is easily deflected and corrected during installing it even when it is warped back and displays heat insulating and soundproofing effects due to a still air layer existing in a slotted strip by forming long slotted strips side by side on the second surface of a platelike laminated material obtained by shred ding bamboos longitudinally and bonding the slender bamboo materials with a widthwise long rectangular cross section in parallel. SOLUTION: Slender bamboo materials 1 with a widthwise long rectangular cross section which are obtained by shredding bamboos longitudinally are bonded together side by side to form a platelike laminated bamboo material 2 having long slotted strips 3 formed side by side at a specified interval on the second surface of the material 2. In order to make almost uniform a warp caused by a year-long time change in the quality of the laminated bamboo material 2 or its forward/backward bending strength, the first and the second surface of the mutually adjacent bamboo materials 1 are reversed and the upper and the lower part thereof are reversed and bonded together side by side as the upper part of the bamboo is narrow and this-walled. The laminated bamboo material 2 is easily deflected on account of the slotted strips 3 formed on the second surface of the material 2.  The laminate of the bamboo materials 2 is tensely installed on the foundation surface of a floor or a wall to form a floor or a wall surface. Consequently, it is possible to easily correct a warp during installing and upgrade heat insulating or soundproofing effects by a still air layer in the slotted strips 3 after the laminated is tensely installed on the floor or the wall material.

Title: Lid of air bag device for front passenger's seat
IPC: B60R21/215
Filed: 1992-03-17
Abstract: PURPOSE:To prevent an air bag for a front passenger's driver's seat from being broken when the air bag is operated. CONSTITUTION:An installation piece 26 is projectingly installed on the back surface of a lid 16, and a tear line 30 is formed at the root part of the installation piece 26. The tear line 30 has not only a groove but a plurality of holes 42 which penetrate through the thickness direction of the installation piece 26. Accordingly, when the lid 16 is opened, being pushed by an air bag, the installation piece 26 is torn along the tear line 30. Since the tear position is the position set along the back surface of the lid 16, the rubbing between the developed air bag and the torn surface is extremely less. Since the smooth surface of the hole 42 exists on the torn surface, the air bag is surely prevented from being broken.

Abstract: PURPOSE:To effectively use this unit for car radios, by avoiding the switching operation while the changing width of the strength of electric field is not so much great, through the hysteresis characteristics given to the switching operation of stereo and monaural to the level change of input signal. CONSTITUTION:The switching unit 21 is provided with the second switching transistor TR19, the base is connected with the connection between the resistances 13, 14 and the capacitor 15 the same as the case with the base of the first switching TR16, and the collector is connected to the base of TR10 via the resistance 20. If the input signal level of FM stereo broadcast is not reached to the specified value, the negative voltage level at the point A is low, TR16 turns on into monaural reception state. Further, in this case, TR19 also turns on, and the base bias of TR10 is lower by the amount corresponding to the resistance 20 inserted in parallel with the resistor 7 than the resistances 6 and 7, resulting that the amplification factor of IF signal by TR10 is comparatively low. Further, if the strength of electric field increases and the negative voltage level at the point A reaches the specified value, TR16 is OFF and stereo demodulation 4 operation is obtained.
