Title: Manufacture of hafnium carbide crystal body
Inventor: OOTANI SHIGEKI
IPC: H01J9/02
Filed: 1980-09-02
Abstract: PURPOSE: To manufacture a hafnium carbide crystal body having a uniform composition by a floating zone (FZ) method by specifying the composition of a rod of a sintered body for feeding a melting zone and starting materials.  
     CONSTITUTION: A rod 3 of a sintered body of starting materials is held by holdings 2, 2 at both ends in an inert gaseous atmosphere. While forming a melting zone 5 by heating the rod 3 by high frequency induction heating with an RF coil 6, the rod 3 is slowly moved downward to form a rod 4 of a hafnium carbide crystal body. When a crystal body having a composition x 1  (C/Hf ratio) is formed by said method, the composition x 2  of a liq. phase coexisting with the crystal body having the composition x 1  is first obtd. using a phase diagram. A rod having the composition x 2  is then put between rods 3, 3 of a sintered body having the composition x 1  after varporizing part of the components during melting, the former rod is melted to form a melting zone 5, and a crystal body is grown. In order to select said rod 3, crystal bodies are grown using rods having various compositions, and a rod causing no change in heating power when the melting zone is moved is used.

Title: Wind-up device for long-size object
Inventor: KOJIMA JUJI
IPC: B65H75/40
Filed: 1987-05-19
Abstract: PURPOSE:To enable stepless fine adjustment in a wind-up device for a long-size object such as an athletic net, etc., by locking the rotation of a rotary body by means of a spring, releasing the locking by means of a lock releasing mechanism, and maintaining the released condition by means of a stopper. CONSTITUTION:As the coil part of a spring 6 is brought into pressure contact from the inside with the drum part 9 of a rotary body 5 around which a long-size object (lope) is wound, the rotation of the rotary body 5 is locked only in one direction due to its frictional force. Then, when an inner cylinder is pressed by a push 13, a turning force is applied to an outer cylinder 12 which is being screwed on the inner cylinder and the diameter of the spring 6 one end 6b of which is engagedly stopped is contracted releasing the locking of the rotary body 5. In this condition, when a stopper is engaged with the hole of the inner cylinder 11, the rotary body 5 is kept in a freely rotatable condition. From this condition, as the engagement of the stopper is released, releasing the pressure of the push 13, the rotation of the rotary body 5 is again locked only in one direction due to the friction with the spring 6. Thus, the fine adjustment of the wind-up/delivery of a long-size object can be easily carried out, without generating noise during the operation while eliminating inadvertent release of looking.

Title: Method for photographing image in scanning electron microscope
Inventor: OKI HIROBUMI
IPC: H01J37/22
Filed: 1992-05-14
Abstract: PURPOSE:To provide a method for phoptographing images using a scanning electron microscope whereby precise sample images can be taken even if the samples are likely to be damaged by heating due to exposure to an electron beam. CONSTITUTION:The portion of a sample to be photographed is disposed on an electron beam optical axis and then a cursor signal is generated from a cursor signal generator 10 and is fed to a cathode-ray tube together with an image signal. As a result, e.g. four cursors are superimposed in a scanned image and displayed on the screen of the cathode-ray tube 9. An operator controls the generator 10 so that the portion of the sample to be photographed is surrounded by the four cursors. In the photographic mode, a scanning signal from a scanning signal generator circuit 6 indicates a relatively slow scanning speed suitable for photographing in the portion of the sample which corresponds to the area surrounded by the four cursors, while in the areas other than that surrounded by the four cursors the scanning speed is held at that for rapid scanning.

Abstract: PURPOSE: To provide a switching power supply by which the temperature change or the drop of an output voltage can be reduced on the low-temperature side even when the temperature change of an output voltage is made large on the high- temperature side. CONSTITUTION: A switching power supply uses the power-supply voltage and the current of a DC power supply 1 at a voltage conversion circuit 2, and it generates a stabilized output voltage Voa which has controlled the switching width of a control signal S1 at a control circuit 4. An error-voltage generation circuit 5A divides the output voltage Vos by a positive-temperature-coefficient thermistor circuit 54A having a positive- temperature-coefficient resistance value and by a resistor 55, and a detection voltage Vda is generated. On the other hand, a reference voltage Vr for a reference voltage source 56 is divided by a resistor 53 and by a negative-temperature-coefficient thermistor circuit 52A having a negative-temperature coefficient resistance value, and a reference voltage Vra is generated. An error amplifier 51 generates an error voltage Vea as (Vda-Vra).  The error voltage Vea is changed linearly with reference to a temperature change on the high-temperature side, and its change is small on the low- temperature side. As a result, the output voltage Voa corresponding to the error voltage has the same temperature characteristic.

Abstract: PURPOSE:To reduce the width of an impurity diffused region superposed under a gate electrode by side-etching the electrode, then implanting a high density impurity to an element forming region, and extending the implanted region by heat treating to below the end of the electrode. CONSTITUTION:After a gate electrode 19 of rectangular section is formed, the electrode 19 under a mask pattern 20 is etched, and the side is etched substantially uniformly to a predetermined width. Thereafter, with the pattern 20 as a mask a high density impurity is implanted by ion implanting to an element forming region near the electrode 19, and high density impurity regions 21a, 22a to become a source 21 and a drain 22 are formed from directly under the side of the pattern 20 toward the outside. Further, the regions 21a, 22a are extended by heat treating to form the source 21 and the drain 22. As a result, the side-etching width absorbs the lateral extension in thermal diffusion to reduce the impurity diffused region superposed with the electrode.
