Title: Crystal boron nitride sintered body and preparation thereof
Inventor: OKUZUMI AYANORI
IPC: C22C29/16
Filed: 1983-08-04
Abstract: PURPOSE:To inexpensively prepare a CBN sintered body having an arbitrary dimension and configuration, by dispersing CBN fine particles having a specific volumetric ratio range in a bonding material obtained by alloying a hard heat resistant inorg. compound and a metal according to a liquid phase sintering process. CONSTITUTION:A fine powder comprising a hard heat resistant inorg. compound (e.g., TiN, WC or AlN), a powder comprising a metal alone (e.g., Ni, Co or Ti) and a CBN powder in a volumetric ratio of 60-40% are mixed. In the next step, this powdery mixture is charged in a mold and pressed to 0.3-3kb under vacuum or in an inert atmosohere and heated to 1,200- 1,600 deg.C to obtain a sintered body. The press heating equipment in this case is a so called hot press apparatus and the sintered body with an extremely large dimension can be obtained by small scale equipment as compared with an ultra-high pressure apparatus and operation is also simple. The above mentioned materials of the bonding material are used in forming a CBN sintered body satisfying requirements without necessitating ultra-high pressure but it is necessary to properly select a combination of various materials and a compounding ratio and a sintering treatment condition such as pressure or a temp. This fact shows possibility such that various CBN sintered bodies having different characteristics can be manufactured according to use purpose.

Title: Production of potassium niobate single crystal
Inventor: KUMAGAI HIROHIKO
IPC: C30B29/30
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a potassium niobate single crystal by a TSSG method, enabling to obtain the potassium niobate single crystal in good controllability in a good yield and at a low cost by adding an alkali metal oxide except the potassium oxide to a raw material melt solution.  
     SOLUTION: This method for producing a potassium niobate single crystal comprises charging a raw material comprising niobium pentoxide, potassium oxide, an alkali metal oxide except the potassium oxide (e.g. rubidium oxide), etc., into a crucible disposed in an oven 4, heating the charged raw material with a heater 5 to uniformly melt the raw material, cooling the obtained raw material melt solution 8 to a temperature of approximately 1057°C, bringing a seed crystal 6 into contact with the raw material solution 8, and subsequently pulling up she seed crystal to raise the potassium niobate single crystal 7. Since the alkali metal oxide except the potassium oxide is thereby contained in the raw material solution, the deposition-initiating temperature of the potassium niobate can be lowered to facilitate the control of a temperature for bringing the seed crystal into contact with the raw material solution. The method for producing the potassium niobate single crystal further enables to retard the growth speed of the single crystal, facilitate the control of the growth with temperature, and improve the quality of the single crystal.

IPC: G06F11/20
Filed: 1983-08-08
Abstract: PURPOSE:To prevent the generation of a serious information processing fault and at the same time to eliminate the need for reswitching control, by deciding the switching between active and standby systems for each generation of fault. CONSTITUTION:When a fault of a computer A of the active system is detected by an alarm detecting part ADT, this fault generation is informed to a typewriter TW, a CRT, a display lamp LP and a buzzer BZ. At the same time, the weight information of the alarm is sent to an alarm importance arithmetic part ALU for calculation of the weight. This calculated weight is sent to an importance comparing part CMP. The part CMP receives the alarm weight of a computer B of the standby system from a weight output part AOU via an input part AIN of the computer A and compares it with the alarm weight arithmetic result of the computer A. If the alarm weight of the computer A is larger than that of the computer B, a switch request signal is delivered to a double system switching control part SWC. In case a CPU of the computer A has a breakdown and an alarm is produced by the break of the CPU power supply, no comparison is carried out for the alarm importance. Then the active system is switched unconditionally to the waiting system.

Filed: 1995-05-17
Abstract: PURPOSE: To conduct a low-speed rotation control accurately as specified by activating a drive means by fluid pressure using a liquid control means and converting a reciprocating motion by this drive means into the rotary motion of a gear member using a conversion means. CONSTITUTION: A pulse signal is connected to a switching valve 22 by a control device 23 to supply air to an air cylinder 7. Further, a valve pressure on an extrusion side or an extraction side is adjusted by the supply of the air from an air supply source 21. Consequently, a specified motional position for a reciprocating cylinder rod 7a is determined by the air pressure brought to bear upon the air cylinder 7. Thus, it is possible to adjust a support rod and a first and a second pusher 5a, 5b connected to the cylinder rod 7a. After that, the reciprocating motion by the air cylinder 7 is converted into the clockwise rotation of a gear 4, resulting in the rotation of a rotary shaft 3 and in turn, the rotation of a rotor 2. A motion is given to bubbles by the rotation of the rotor 2 in a paint, so that the bubbles are caused to ascend and then are removed.
