Title: Production of star sapphire
Inventor: KUNUGI MASANAO
IPC: C30B25/00
Filed: 1985-02-15
Abstract: PURPOSE:To produce a star sapphire having high quality comparable to natural star sapphire, easily, by subjecting a sapphire crystal composed mainly of Al2O3 and containing iron as a colorant to (plasma) CVD treatment in TiCl2 atmosphere. CONSTITUTION:A sapphire crystal composed mainly of Al2O3 and containing at least iron (e.g. Fe2O3) as a colorant is subjected to CVD or plasma CVD treatment in TiCl4 atmosphere, and then heat-treated in air or in an O2- containing atmosphere to produce a star sapphire. The control of color tube and the elimination of crystal defect caused by the dissolution of TiO2 in solid crystal during the crystal growth, which are impossible by conventional synthesis, can be carried out, and a star sapphire having a quality comparably high to natural jewel exhibiting clear star effect can be produced easily by this process.

Title: Driving circuit of output switching transistor
Inventor: HOSODA KATSUJI
IPC: H02M1/08
Filed: 1982-02-23
Abstract: PURPOSE:To prevent a malfunction although the superposition of time occurs in a driving pulse, by avoiding the generation of an output at the secondary side in case two pulse transformers are driven at one time. CONSTITUTION:When the driving pulse is applied to a terminal 14 or 24, a transistor TR is turned on to flow the current to the primary side winding of a pulse transformer. As a result, a TR15 or TR25 with the base terminal connected to the secondary side winding is turned on. When the driving pulse is applied to both terminals 14 and 24 at one time, the current flows to the primary side winding of both pulse transformers 10 and 20. In this case, both the current flowing to the 3rd side winding 13 of the transformer 10 and the 3rd side winding of the transformer 20 are turned forward. As a result, the impedance of the 3rd side winding becomes zero when it is viewed from the primary side winding to flow no current to the secondary side winding.

Filed: 1980-03-05
Abstract: PURPOSE:To contribute to the enhancement of insulation of the molded coil by a method wherein a fiber reinforcement member protruding on the base part of lead conductors are cut off and the cut end part is joined to the side face of lead conductors. CONSTITUTION:The fiber reinforcement being impregnated with a thermosetting resin is wound around on a spool 1 to form an inside insulating layer 3, a winding conductor is wound around on it to form a winding 4 and the lead conductors 5 of the winding 4 are provided. The fiber reinforcement being impregnated samely with the resin is wound around on the winding 4 to form an outside insulating layer 6. Accordingly the protruding part 6a of the fiber reinforcement is formed on the base part of the conductors 5. Thereupon when the quantity of the protruding part 6a corresponding to the size of breadth of the conductors 5 is cut off and the cut end part thereof is joined to the side face of base part of the conductors 5, the protrusion can be eliminated. Then after the fiber reinforcement being impregnated samely with the resin is wound around on the outside insulating layer 6 to form an outermost insulating layer 9, it is heat-treated. Accordingly because no gap 7 is generated at the both sides of base part of the conductors 5, the insulation can be enhanced.

Title: Current measuring device
Inventor: TAMURA KOUZOU
IPC: G01F1/66
Filed: 1980-03-07
Abstract: PURPOSE:To obtain a current measuring device which eliminates the effect of multiple reflections by disturbances by providing a delay circuit having the delay time of a fixed time at the intermediate of a transmitter and a receiver. CONSTITUTION:Ultrasonic wave pulses from a radio transmitter 5 is diagonally emitted from a transmitter 1 via a change-over device 3. The reflected waves (solid line) of a valve 7 in which fluid flows are received in a receiver 2 and are received in a receiver 4 via the change-over device 3. Further, a delay circuit 8 is provided between the receiver 4 and the transmitter 5. The signals of the transmitter 5 and the receiver 4 are frequency-communicated at 9 and are counted with a reversible counter 10, the outputs whereof are stored by a memory device 11 and are displayed 12. If the device is constituted in this way, the ultrasonic pulses T0-T3 emitted to the transmitter 5 as shown in the figure are delayed 8 and this results in that they are emitted at TD1-TD3, thus the receiving waves are received at rD0-rD2. As against this, the reverberant waves such as of wavelines are rD01, rD02 with respect to TD0 and rD11 with respect to TD1 and therefore the received waves are measured without receiving the effect of reverberant waves.
