IPC: C30B33/02
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To inhibit deterioration of crystal properties without generating any deposit within a crystal and to obtain a crystal having low electric resistance by adjusting the cooling rate of the crystal after the heat treatment to a value within a prescribed range, in the heat treatment that comprises subjecting a ZnSe crystal grown by a chemical transport method using iodine as the transport medium, to heat treatment in a Zn vapor atmosphere. SOLUTION: The cooling rate of a ZnSe crystal after this heat treatment is adjusted to 1 to 200 deg.C/min. In the heat treatment, the ZnSe crystal that is an object of this heat treatment and metal Zn are heated to 800 to 1,100 deg.C and 750 to 1,100 deg.C, respectively so that the temp. difference between them is adjusted to 0 to 50 deg.C and, under such conditions, the ZnSe crystal is subjected to heat treatment desirably for 50 to 200hr. The figure shows a conceptual drawing of a device for performing this heat treatment. In the device, a ZnSe crystal grown by a chemical transport method using iodine as the transport medium is held in a quartz reaction tube by supporting the crystal with a quartz member, and also, metal Zn is received at the bottom of the quartz reaction tube, and then, the quartz reaction tube is evacuated to 3×10<-7> Torr, and thereafter sealed.  Subsequently, the quartz reaction tube is placed in a heat treatment furnace and the crystal area and the bottom area in which the metal Zn is placed are heated to 1,000 deg.C and 980 deg.C, respectively, and then, the ZnSe crystal and the metal Zn are maintained under such respective conditions for 100hr.

Title: Electron beam assistant processing equipment
Inventor: NAKASUJI MAMORU
IPC: C23F4/00
Filed: 1989-08-18
Abstract: PURPOSE:To simultaneously observe a sample together with working or deposition by providing an equipment for forming lines of magnetic force in order to greaten the traveling distance until secondary electrons are made incident into a secondary electron detector. CONSTITUTION:An equipment for forming lines of magnetic force is provided in order to change the orbit of secondary electrons emitted from a sample 12 in the interval of both the sample 12 and a secondary electron detector 10 and to greaten the traveling distance until the secondary electrons are made incident into the secondary electron detector. Therefor the secondary electrons emitted from the sample are trapped by this strong magnetic field and not easily made incident into the secondary electron detector 10. The secondary electrons are multiply traveled around the lines of magnetic force of this magnetic field. Electron-ion pairs are formed by more collisions against the molecules of reactive gas. Energy is lost by collision against the molecules and thereafter the secondary electrons are made incident into the electron detector 10. Thereby a great secondary electron signal can be obtained even in the reactive gas at low pressure. This signal is simultaneously processed by an electron microscope and the image of the sample 12 is displayed on an indicator such as a CRF.

Title: Actuator for head of magnetic disk device
Inventor: OGUCHI SHIGEMITSU
IPC: G11B21/02
Filed: 1987-08-28
Abstract: PURPOSE:To suppress the quantity of the thermal off track of a magnetic head to a minimum by regulating the one end of the same direction of respective rotary cylinders to an axial direction, thermally expanding the other end and matching the thermal expanding direction of the respective rotary cylinders to the thermal expanding direction of the spindle side of a disk. CONSTITUTION:A spacer ring 14 is interposed between the bearing 3b of the upper rotary cylinder 2 and an adjusting screw 5 and a pressurizing spring 4 is disposed between a bearing 3a and a flange 12, so that the upward movement of the upper rotary cylinder 2 is regulated to thermally expand downward and make the direction of the thermal expansion the same as that of the lower rotary cylinder 2 and the spindle side. Therefore, the heat of a spindle motor etc., is transferred to the respective rotary cylinders 2, and then, it is thermally expanded to similarly displace the magnetic disk mounted on the spindle and the magnetic head mounted on the rotary cylinder 2. Thereby, the quantity of the thermal off track of the magnetic head is extremely reduced.

Title: Commutation type dc circuit breaker
Inventor: YOSHIDA TORU
IPC: H01H33/59
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To minimize a capacitive increase in a capacitor, to obtain a large commutation current and to improve breaking performance of a circuit breaker by arranging a saturable reactor in the main circuit current carrying part between a main contact point and a commutation circuit, and closing a commutation switch after opening the main contact point. SOLUTION: When cutting off a main circuit current flowing in a DC power source 11-a main contact point 1-a load 12, the main contact point 1 is opened, a commutation switch 4 is closed, and an oscillating commutation current in the inverse direction of the main circuit current is carried to the main contact point 1 to make an electric current zero point between the oscillating commutation current and the main circuit current. When the main circuit current is larger than, for example, several 100 A, a saturable reactor 3 becomes small reactance, so that a large oscillating commutation current can be carried in the beginning of flowing the oscillating commutation current.  When the main circuit current reduces and becomes several 100 A or less since the oscillating commutation current flows, since reactance of the saturable reactor 3 suddenly increases, a frequency of the oscillating commutation current reduces, so that di/dt at an electric current zero point reduces.

Filed: 1988-08-30
Abstract: PURPOSE: To save an extra driver, e.g. a motor or a magnet, by an arrangement wherein a motor can drive a further function, e.g. ink ribbon advance, through an eccentric ring and a rotary lever and a motor for printing a selected character functions separately. CONSTITUTION: A cam 5 and an eccentric ring 12 are secured to the motor shaft 4. The roll 13 of a turnable lever 14 abuts against the eccentric ring and the pivot shaft 15 of the lever 14 is fixed similarly to a stand 2. When the motor turns, a hammer 6 is moved toward a platen 9 by means of the cam 5. The eccentric ring 12 is turned simultaneously with the cam 5.

The rotational motion is transmitted through a coupling part 20 to an ink ribbon. According to the structure, many functions can be driven by a same motor in addition to a print hammer and an ink ribbon.
