IPC: C30B15/10
Filed: 1989-06-07
Abstract: PURPOSE:To reduce the amount of a raw material in a crucible at the time of completing pulling-up and to enhance the production yield of crystal by utilizing a crucible which is formed by fitting a cylindrical inner layer holding vessel to the inside of an end-closed cylindrical outer layer holding vessel in the case of pulling up and growing crystal in a molten layer method. CONSTITUTION:A crucible 1 wherein only side part is constituted of a double structure is formed by fitting a cylindrical inner layer holding vessel 1b to the inside of an end-closed cylindrical outer layer holding vessel 1a. Then a material 7 for crystal is supplied to this crucible 1 and heated by a heater 2. Melt 6 is pulled up to the upper part to grow crystal 5 while melting the raw material toward the lower side from the upside.

Title: Electronical part container
Inventor: NAKAJIMA HIROSHI
IPC: H01L23/00
Filed: 1987-06-11
Abstract: PURPOSE:To prevent the bending of a lead pin and thus eliminate defective integrated circuit elements by minimizing the contact between the end of the lead pin and the side wall of a pallet through the provision of the pallet wherein a rib is formed for guiding a package in the recess of the pallet and in such a dimensional relationship with the package as to permit the package to return within the rib guiding area, if the package jumps out of the rib. CONSTITUTION:A package 1a is guided by a rib 2a in such manner that a clearance x is maintained between the end of a lead pin 1b and side wall 2b, even if the variation of the size of the end of lead pin 1b becomes maximum within the allowable variation range. If the package 1a of an integrated circuit element 1 is run onto the rib 2a, the end of lead pin 1b is brought into contact with the side wall 2b of a pallet, exerting a reactive force on the package 1a for the return to the original guiding area of the rib 2a. Moreover, if the end of the lead pin 1b and the side wall 2b are brought into contact, the package 1a can be smoothly received back into the original guiding area of the rib 2a, since the contact therebetween takes place in such a dimensional relationship as to cause a slight slope at a contact point 3.

Abstract: PURPOSE: To improve the processing speed without newly providing a special agreement with a host computer by a method wherein an interface with the host computer is held, and at the same time, the receiving process and the expansion process of compression image data being split and transferred are performed in parallel. CONSTITUTION: The CPU 10 of an image plotting device ensures a memory region of a specified capacity to be used as an input buffer, from a common memory 16 as a data receiving preparation. Then, at a host interface control unit 14, when data is received, the received data is stored in the input buffer in the common memory 16, and then, whether the received data is image data or not is judged. If the received data is image data, an image expansion process to expand compressed image data to the image data for output is performed at an image expansion unit 18. The image expansion process is controlled by an image expansion control unit independently from the CPU 10.

Abstract: PURPOSE:To execute sterilization while suppressing the difference of a temperature in a sealed container and the dispersion of the temperature between the containers with heating efficiency corresponding to the difference of conductivity, etc., to be caused by the kind of chemical or the size of the sealed container by spreading a rail, which supports the bottom surface of the sealed container, in an irradiation furnace and forming the rail to be low in the entrance side of the irradiation furnace and to be high in the exit side of the furnace. CONSTITUTION:The cross section of a rail 40 is step-shaped and a first step part 79 is fitted to a wasps' nest-shaped groove 80 on the floor surface of an irradiation furnace 71 so that the rail 40 can not fall off upward. A second step part 80 of the rail 40 is protruded higher than the floor surface of the irradiation furnace 71. When an ample (a) is inclined, this second step part 80 is abutted to the bottom surface of the ample (a) so that the bottom surface of the ample (a) can not be directly in contact with the floor surface of the irradiation furnace 71 and spark can be prevented from being generated. An inclined part 40' is formed in the rail 40. With this inclined part 40' as a boundary, a front side 40a (the entrance side of the irradiation furnace 71) is made low and a back side 40b (the exit side) is made high.

Title: Digital positioning controller for magnetic head
Inventor: ARAI YOSHIO
IPC: G11B21/10
Filed: 1989-06-09
Abstract: PURPOSE:To improve the normal following characteristic of a magnetic head and to reduce a position error between the position of the magnetic head and that of a data track by inserting in serial digital filters generating sine waves having the frequencies from the frequency same to rotary frequency of the magnetic disk corresponding to respective tracks to the frequency of an integral times into an open loop. CONSTITUTION:The digital filters generating plural sine waves having arbitral and different frequencies are inserted into the open loop in serial. Consequently, the compressibility of the position error for a target value can be increased much more even if an eccentric mode equal to the rotary frequency of the magnetic disk owing to the eccentricity of the spindle of the motor 8 rotating the magnetic disk and eccentricity when the magnetic disk is clamped is large, and even if the eccentric mode of various frequencies owing to the resonance of an FDD device and the like is large. Thus, the magnetic head 9 can be caused to precisely follow the target data track under a low sampling frequency, and the position error between the magnetic head and the data track position can be reduced.

Title: Recording device and reproducing device
Inventor: KOIDE JINICHI
IPC: G11B33/02
Filed: 1990-06-05
Abstract: PURPOSE:To prevent the invasion of dust from a recording medium inserting port by feeding air to the nozzle of the inserting port by a fan motor and generating an air curtain. CONSTITUTION:Air is sucked from a suction hole by the operation of a cooling fan motor 8, and after cooling internal equipment in a magnetic recording/ reproducing device 1, the cooling air is exhausted from a rear face. At that time, the inside of the device 1 becomes negative pressure and air containing dust 9 tries to flow from the recording medium inserting port 3 into the device 1 in the arrow C direction. However, air sent by the operation of the fan motor 5 is blown out of a nozzle 7 through a guide pipe 6 and an air curtain D is generated on the inlet 3. Thereby, the invasion of dust 9 from the inlet 3 into the device 1 can be prevented by air convection capable of colliding with the lower part of the inner periphery of the inlet 3.

Abstract: PURPOSE:To provide the titled mechanism enabled in the accurate detection of a color change, by decelerating a ribbon feed speed in the vicinity of a color change by providing a feed amount detector of a thermal transfer ink ribbon while detecting the color change by a color sensor. CONSTITUTION:The feed amount of a thermal ribbon 3 is detected by counting the output of a rotation detector 24 comprising a rotary disc or an optical sensor in a counter 25 and, when said feed amount reaches a predetermined value, the speed reduction order of the rotation of a wind-up motor 28 is applied to a motor drive circuit 27 from a motor slow-down circuit 26 to lower the speed of the ribbon 3. On the other hand, the change in the output level of a color sensor 29 is detected by a level detector 30. When the boundary of colors comes to the sensor 29 having two sensor elements 20a, 20b, the level between the sensor elements 20a, 20b becomes different and color change is detected by a color change detector 31 while an order is issued to a motor brake circuit 32 to stop the wind-up motor 28. Therefore, the order color of the thermal ribbon 3 can be mounted over the total width of the printing range of a thermal head.
