Title: Multi-processor system
Inventor: HARA KENJI
IPC: G06F9/52
Filed: 1983-09-24
Abstract: PURPOSE:To prevent the reduction of the executing speed of a general-purpose CPU by providing a timing signal generator to occupy an RAM for a period of time needed for a 1-chip CPU to access the RAM. CONSTITUTION:When the 1-chip CPU1 is going to read out the data on RAM2, a timing signal generator 3 inhibits the reading action of the CPU1 to disable to access the RAM2. However the generator 3 works sequentially to separate a bus buffer 4 immediately before the CPU1 accesses the RAM2. In the same way, a WAIT signal is transmitted from a WAIT signal transmitting part 7 when a general-purpose CPU is going to access and RAM2 to hold the general-purpose CPU on standby. Therefore the RAM2 is occupied for a period during which the CPU1 accesses the RAM2. Thus the data can be read. Thus the period of time during which the CPU1 occupies the RAM2 can be reduced. This ensures the high processing efficiency for the main general-purpose CPU.

Abstract: PURPOSE:To provide the titled sputter source enhancing the uniformity of a film thickness  to a wafer circularly arranged to the lower part, constituted by providing a ring shaped  permanent magnet respectively having magnetic poles on the same planes of an inner and an outer peripheral surfaces thereof and a ring shaped magnetic pole concentrically provided  around the permanent magnet and movable to a vertical direction. CONSTITUTION:A ring shaped magnetic pole segment 11 is driven by a drive apparatus so  as to always repeat swing motion between a surface (an A position) same to the ring shaped  permanent magnet 10 and a surface (a B position) not entirely including a surface containing  the magnet 10 during plasma generating time. In this structure, when the magnetic pole  segment is positioned at the A position, line of magnetic force issured from the magnetic  pole of the outer peripheral surface of the magnet 10 is attracted by the magnetic pole segment 11 to be passed along a broken line route 17 and a point crossed with an electric field at  right angles is formed into a large ring like shape. On the other hand, when the magnetic pole segment 11 is positioned at the B position, line of magnetic force issued from the magnetic pole 11 of the outer peripheral surface of the magnet is directly curved to be passed  along a solid line route 16 (a shortest route), that is, to be formed into a small ring like  shape. Therefore, as the magnetic pole segment 11 is swung between the positions A and B, the crossing point of the electric field and the magnetic field is swung as described above  and the uniformity of a film thickness formed to a wafer 15 by a targent 13 can be easily held.

Title: Gas mass flow rate control device
Inventor: MIYOSHI HIDEKAZU
IPC: G05D7/06
Filed: 1987-07-16
Abstract: PURPOSE:To allow a master control part to control the flow rates of many kinds of process gases by correcting a previously stored conversion factor for a reference gas control master signal outputted from the master control part and converting the signal into the one for the reference gas. CONSTITUTION:A gas conversion factor storing part 6a in a gas factor correcting part 6 previously stores conversion factors based upon the specific heat ratios of various inherent gases against the reference gas. When a selection signal SN corresponding to gas to be used, the storing part 6a outputs a conversion factor signal SK, a multiplier part 6b outputs a master control signal SuN for inherent gas which is obtained by multiplying an upper signal Su for the reference gas by the conversion factor SK and a flow rate control signal SC from a comparing control part 7 adjusts a gas flow passing a control valve 8. Since an output signal from the master control part 5 is outputted through the gas factor correcting part 6, the signal for all the process gases goes to the same as a reference gas flow control signal and the master control part 5 can be standardized for the reference gas.
