Title: Process for checking leakage of pulling device for pulling silicon single crystal
Inventor: MATSUDA MASATO
IPC: C30B29/06
Filed: 1985-05-29
Abstract: PURPOSE:To execute leak check of a pulling device of a silicon single crystal simply by determining the amt. of leakage of oxygen corresponding to the amt. of pulling from a difference between the amt. of leaked oxygen during maintaining in vacuum state and the amt. of leaked oxygen in the condition of flowing inert gas. CONSTITUTION:After maintaining a pulling chamber 8 at a degree of vacuum by sucking with a vacuum pump to a fixed range, the vacuum is adjusted to can 10-20Torr by feeding inert gas from a feeding port 9, the melt of silicon is prepd. with a heating device, and a single crystal of silicon is pulled while dipping a seed crystal in the melt. In this stage, decrease of yield of the silicon single crystal and deterioration of the quality of the single crystal may not be avoided by only checking leakage before commencement of pulling because of increase of leakage of oxygen accompanying the change of pressure in the furnace, and oxidation of crucible and the heater and mixing of the oxidized product in the silicon single crystal. To eliminate such disadvantage, the sealing of the furnace should be improved or the amt. of feed of the inert gas is increased and the increased amt. of the inert gas should be sucked with the vacuum pump, when the leakage of oxygen is increased. The amt. of the leaked oxygen is measured just before pulling by attaching an oxygen sensor.

IPC: H02K5/04
Filed: 1979-09-11
Abstract: PURPOSE:To allow the rotor to be withdrawn from the stator holding the rotor in place by forming the inner diameter of a bearing bracket larger than the outer diameter of the coupling with an internal bracket provided inside the bracket. CONSTITUTION:The internal bracket 17 is provided inside the bearing bracket 4 of the coupling 2 and fixed with a bolt 18. Here, the outer diameter of the internal bracket 17 is made smaller than the outerdiameter of a rotor iron core 11 while the inner diameter of the bearing bracket from 4 larger than the outer diameter of the coupling 2.

Title: Multiprocessor and interrupt arbitrator thereof
Inventor: FUKUDA MUNEHIRO
IPC: G06F13/26
Filed: 1991-04-22
Abstract: PURPOSE: To distribute I/O interruptions to respective processors by arbitrating the interruptions by using parameters showing the load states of the processors as 1st priority PPR and additionally selecting one processor according to 2nd interruption priority RRPR which varies cyclically unless one processor is not determined. CONSTITUTION: Data of PPR 11 and RRPR 12 are temporarily stored in a buffer 15. The PPR 11 specifies the priority of an I/O interruption corresponding to the execution priority of a process and is used for 1st arbitration based upon the execution priority of the process. The RRPR 12 of each interrupt arbiter is a counter which cyclically counts within the range of the number of the processors and initialized to characteristic priority when the system is actuated to have a different value from any other interrupt arbiter. An encoder sends a selected request signal varying in interruption request level to control logic 14, which is actuated to inhibit an arbitration line 4 to a bus arbiter from being used.

Title: Discriminator
Inventor: FUKUSHIMA NOBUO
IPC: G11B19/04
Filed: 1986-05-21
Abstract: PURPOSE:To discriminate recording/unrecording in a short time by detecting a signal level of a track sequentially and discriminating it as the presence of recording before a signal level over all range of tracks is detected when the level reaches a prescribed reference value. CONSTITUTION:A recording presence detection circuit 85 is constituted to detect the presence of an RF signal when a recording signal is, e.g., an RM signal, and outputs a high level signal when the recording exists. A system controller 91 uses the circuit 85 so as to sample the RF detection output level in the timing of FG for the signal, e.g., on a track. When the RF detection output level detected sequentially along the track reaches a prescribed reference value, before the signal level over the entire range of the track is detected, it is discriminated to have recording at the track position. Thus, the recording/ unrecording is discriminated in a short time.
