IPC: C30B17/00
Filed: 1993-06-04
Abstract: PURPOSE:To improve the yield by reducing the temp. gradient in a molten material in a specified crucible in accordance with the case when the gradient is large or small. CONSTITUTION:A bottom plate 101 consisting of a first layer 102 of pBN, a second layer 103 of pG (pyrolytic graphite) and a third layer 104 of pBN and a side plate 105 consisting of the laminate of pBN are combined to form a crucible 100. The material is placed in the crucible 100 and heated by a heater, and a seed crystal is brought into contact with the obtained molten material to grow a crystal. Subsequently, when the temp. gradient in the crystal growth direction becomes larger than expected, the heat transfer coefficient of the bottom plate 101 vertical to the crystal growth direction is made extremely large to prevent the excessive increase of the temp. gradient, and the excessive decrease of the temp. gradient is obviated when the temp. gradient becomes smaller than expected. A compd. semiconductor crystal is grown and produced under these conditions.

Title: Flow rate control valve
Inventor: KITAMURA KAZUHIKO
IPC: F02M23/08
Filed: 1979-10-19
Abstract: PURPOSE: To eliminate the leakage of fluid in a spool-type flow control valve by a simple construction.  
     CONSTITUTION: During the fixed speed running of a car, since the upward thrust given to a piston 16 by the pressure difference between an upper chamber 18 and a lower chamber 19 is smaller than the load of a spring 20, a valve spool 13 is pushed downward. By this pushing force, the valve spool 13 cuts off a passage 13a from a chamber 26, and a valve 27 is brought in contact with the top face of a sleeve 12. Consequently, the air on the side of an entrance 11a can be leaked to the chamber 26 via the passage 13b and the relative sliding part between the valve spool 13 and the sleeve 12. But, since the flow from the chamber 26 into the inner hollow of the sleeve 12 is checked by the valve 27, the air flow from the entrance 11a to an exit 11b is checked. For deceleration, the negative pressure in an intake manifold 21 is increased, and as the entrance 11a is connected with the exit 11b, purified air is supplied into the menifold 21.

Abstract: PURPOSE:To simplify structure and to reduce the number of parts by unidirectionally energizing a moving lens group by the elastic force of the flexible printed board or the lead wire of an iris unit. CONSTITUTION:The moving lens group 30 is guided by a guide pole 22 so that it can be moved forward and backward. When a cam barrel is rotated in a state where the cam pin 44 of the lens group 30 is inserted in the cam groove of the cam barrel, the lens group 30 is moved forward and backward in the relation of a prescribed zoom ratio decided by the cam groove. The iris unit 58 is integrally fixed to the lens frame of the lens group 30. Then, the flexible printed board 62 of the unit 58 is fixed to a lens barrel main body 10 with a screw 63 in a state where it is bent in an almost U-shaped. As the result, since the lens group 30 is always unidirectionally energized by the elastic force of the printed board 62, backlash between the pin 44 of the lens group 30 and the cam groove of the cam barrel can be eliminated.

Abstract: PURPOSE:To simplify the circuit constitution, to eliminate the design limitation and to reduce invasion of noise or production of distortion considerably by providing a control circuit having a sound volume adjusting function and a muting function. CONSTITUTION:A sound volume decrease switch 8a or a sound volume increase switch 8b of a sound volume adjusting switch 8 is operated to adjust the sound volume of an audio signal. Thus, a control signal in response to the operation is outputted from the control circuit 7 to a control terminal 4a of an electronic attenuator 4. With a mute request signal outputted from a muting signal source 9, the control circuit 7 based on a built-in program outputs a control signal to the electronic attenuator 4. Then the circuit 7 sets the attenuator of the sound volume adjustment set to the electronic attenuator at a maximum. Thus, the audio signal is entirely attenuated and not sent to a power amplifier 6. Then when a mute release request signal is outputted from the muting signal source 9, the control circuit 7 sets the attenuation of the electronic attenuator 7 to the attenuation set for the sound volume adjustment.
