Title: Crucible for growing single crystal
Inventor: IWAKI TADAO
IPC: C30B15/10
Filed: 1980-10-31
Abstract: PURPOSE: To obtain an inexpensive crucible with a low coefft. of thermal expansion and a superior heat insulating property for growing an oxide single crystal with a high m.p. by coating the surface of a crucible made of refractory such as alumina with a metal such as iridium.  
     CONSTITUTION: The whole surface or the inside of a crucible 2 made of refractory such as alumina, zirconia or boron nitride is coated with a metal such as iridium, platinum, rhodium or molybdenum to manufacture a crucible for growing an oxide single crystal. Since the thickness of the metal is only about 100μm, the crucible is obtd. at a low cost. The thick-walled part of the crucible is made of refractory, so a superior heat insulating property is provided, and the constitution of the refractory is simplfied. The crucible has a low coefft. of thermal expansion. Accordingly, the resulting single crystal is not cracked, and the crucible itself is not damaged.

Title: Television equipment
Inventor: JIEEMUSU HARISON DOTEI ZA SEKA
IPC: H04N3/18
Filed: 1988-06-23
Abstract: PURPOSE: To protect the television receiver from an excessive alta voltage to generate X-rays by generating a signal used to prevent production of switching and to reduce an output voltage on the occurrence of a 3rd signal generated when a frequency transition edge is lost. CONSTITUTION: On the occurrence of a fault state, a high voltage protection circuit 301 generates an inhibit signal 301a and inactivates a signal OH. On the other hand, s signal O32 H is generated even on the occurrence of the fault and a pulse DHa is generated at an output terminal 61a of a monostable multivibrator 61 even when the signal OH is inactivated as a result of the operation of a frequency divider circuit 45, a ramp wave generating circuit 37, a comparator circuit 38 and a flip-flop 61, and given to a base electrode of a transistor (TR) Q2 via a resistor 302 and when an alter voltage U exceeds a predetermined permissible level, production of the signal DH is prevented. When the signal OH is inactive by a protection circuit 301, a flip-flop 303 keeps the TR Q2 nonconductive. Thus, the production of the alta voltage U is prevented.

Filed: 1984-07-23
Abstract: PURPOSE:To obtain easily a material having a prescribed transformation point and to make the material easily cold-workable even at the temp. above the transformation point by infiltrating a prescribed amt. of an infiltration type element into a shape memory alloy. CONSTITUTION:An Ni-Ti alloy or the like is used for the shape memory alloy and an element such as C or N which does not react with metals is used for the infiltration type element. The raw material components compounded to a prescribed ratio are first cast by plasma melting, etc. to form a billet which is then successively worked to a wire, plate, etc. The transformation point is measured in the mid-way of the working, and if the measured points deviates from the intended transformation point, the infiltration type element (for example, an aq. graphite dispersion) is brought into contact with the alloy and the alloy is heated to infiltrate the infiltration type element into the alloy by diffusion as much as the deviation. The infiltration rate of the infiltration type element is adjusted by the temp. and time in the stage of infiltration. The shape memory alloy having the prescribed transformation point is thus easily obtd.
