Title: Address conversion circuit
Inventor: OKADA MASAYUKI
IPC: G06F12/10
Filed: 1984-06-25
Abstract: PURPOSE:To increase the processing speed of an address conversion circuit by using a double port RAM to check whether or not the pages of both former and latter halves are put within a main memory in case the operand corresponding to a logical address is spread over a page boundary. CONSTITUTION:The head operand which designates the pages of a former half is set to a logical address register LAR1. The segment number and the page number of the logical address LA are used to give an input to an address input 1 of a TLB memory 10 of a double port RAM. Thus a former half page address 1020 is delivered together with the information 1021 show in the presence or absence of an address within the TLB. The information 1021 is supplied to a TLBHIT check circuit 3 together with the segment and page numbers of the LAR to check whether or not the former half pages are put within the TLB. While the operand length is added to the value of the LAR by an adder 2 for the latter half pages to obtain the segments and page numbers for the similar processing as the former half pages.

Title: Tilt mechanism of electronic equipment
Inventor: KAGAMI YOSHIJI
IPC: G12B3/02
Filed: 1990-05-22
Abstract: PURPOSE:To secure torque resistance and suppress the extent of its decrease by providing a wedgelike sectioned annular groove or projection which engages it opposite a rotary shaft and a friction material which abuts on it, and clamping a fitting part from its outer periphery. CONSTITUTION:The friction material 2 which has the annular projection (or groove) 2a corresponding to the rotary shaft 1 which has the wedgelike annular groove (or projection engaging it) 1a is engaged with the rotary shaft 1 and the fitting part is clamped by a fitting member 3 from the outer periphery. Consequently, a large frictional force is generated by utilizing the wedge effect of the fitting part to sufficiently secure the torque resistance performance of the rotary shaft 1 though a clamping force is not made large so much. Further, even if the fitting part wears away, the decrease rate of the torque resistance performance becomes small by the effect.

Title: Bump formation
Inventor: SAKAI TADAHIKO
IPC: H01L21/60
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a bump formation method which forms a high bump on an aluminum electrode of a chip, without reducing junctional strength of the chip after soldering. SOLUTION: A copper bump 4 is formed by wire bonding on an aluminum electrode 2 of a chip 1, and a distal end of the copper bump 4 is pressed to have a flat surface. A gold bump 7 is formed by wire bonding on the flat surface. When the bump comprising the copper bump 4 and the gold bump 7 is soldered to an electrode 12 of a substrate 11, the content of solder 13 such as tin which diffuses in the gold bump 7 is blocked by the copper 4 and it does not reach the aluminum electrode 2. Accordingly, formation of alloy layer of aluminum and tin which may deteriorate the junctional strength is avoided. Further, as the solder 13 is prevented by an oxide film on the surface of the copper bump 4 and it does not reach the electrode 2, corrosion due to the solder 13 does not occur in the aluminum electrode 2.

IPC: H03B5/36
Filed: 1992-05-25
Abstract: PURPOSE: To provide a crystal oscillation circuit, which almost instantaneously generates an oscillation output signal that is provided with a needed electrical characteristic, when a system that has a sleep mode to reduce power consumption is switched to the operation of a normal mode. CONSTITUTION: Though a current amount that is supplied to an amplifier 16 in a sleep mode is sufficient to maintain oscillation of a crystal resonator 11, it maintains the oscillation as a current level which is not sufficient to generate a crystal oscillator circuit output signal that is provided with a needed electrical characteristics. Thereby, when the current amount that is supplied to the amplifier 16 is increased to be a value sufficient to generate an oscillator output signal by switching the sleep mode to a normal mode, it can very quickly be shifted to a normal mode.

Abstract: PURPOSE: To ensure safety operation by detecting non-control status by a fault detector and automatically turning off all system power supplies, then displaying the fault when the non-control status occurs due to the fault of a chopper to constitute a magnetic field controller.  
     CONSTITUTION: DC motors DM 1  to DM n  send cloth S through rollers R 1  to R n  and dancer rollers DR 1  to DR n  and detect displacement due to their non-regulated speed, then magnetic field coils FC 1  to FC n  are controlled with a chopper CH. When the magnetic field is not controlled due to the fault of the chopper, the detectors corresponding to the fault detectors set up per speed-regulated line operate and the fault is displayed by a display unit (DP). At the same time, contacts ms 1  and ms 2  are opened by an automatic cut-off circuit (ABC) and both armature and magnetic field power supplies are disconnected. As a result, the non-control fault can be prevented and safety operation is enabled.
