Title: Roller bearing unit for straight sliding
Inventor: TERAMACHI HIROSHI
IPC: F16C29/06
Filed: 1986-10-30
Abstract: PURPOSE:To prevent any edge load from being generated on a contact surface by bringing a roller and the surface of a straight rail to be in contact with the roller into circular surface contact with each other for making the contact state between both said elements to be constant. CONSTITUTION:A straight rail 2 is in a round bar-like form, and the outer circumferential curvature thereof is kept constant over the whole surface, and the curvature of a roller 8a... which is in contact with the outer circumferential surface of the straight rail 2 is also kept constant. Thereby, even though the contact position of the roller 8a... with the outer circumferential surface of the straight rail 2 differs, the contact angle of the roller 8a... is constant and kept excellent at all times. Accordingly, even though the contact position on the outer circumferential surface varies, the contact angle of the roller 3a... is constant so that any edge load can not be generated on the roller.

Title: Input hysteresis circuit
Inventor: HIRAMATSU MAKOTO
IPC: H03K3/0233
Filed: 1985-11-21
Abstract: PURPOSE:To prevent the fluctuation due to the load of the next stage and to use a non-inverting input to other input to be compared by providing a hysteresis circuit between an input transistor (TR) and an output TR and giving a hysteresis without feeding back the output of a comparator. CONSTITUTION:A circuit comprising a diode D1 and a TR Q3 is added to an input stage of the comparator. One input voltage VIN1 changes from an H level to an L level and then to an H level and other input voltage VIN2 is made constant. When the input voltage VIN1 falls down and base potentials VP1, VP2 of TRs Q4, Q5 are nearly equal, a current flowing to the diode D1 flows to the TR Q3 and the potential VP1 descends more rapidly than the potential VP2. Thus, the TR Q5 is turned off and an output voltage VOUT is inverted to an H level. Since the potential VP1 is changed by a nearly voltage drop VBE of the diode D1 near the threshold voltage in this way, the hysteresis HYS of the voltage VBE is formed in comparing the input voltages VIN1, VIN2.

Title: Branch resolution method, processor and system
Inventor: PRADIP BOSS
IPC: G06F9/38
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To shorten the average resolution time of conditional branch instructions by inhibiting the branch estimation orienting transmission of a target address to an instruction fetch unit when a branch instruction can be resolved. SOLUTION: If it is regarded that the instruction which produces the dependence condition codes in a given cycle of a branch scan is not dispatched and the branch cannot be resolved, the subsequent steps are inhibited after the branch is resolved for a branch instruction and the dependence is put on the branch estimation. If it's estimated that a T/NT-branch history table is asserted and branched in a given cycle, the transmission of a branch target address is possible to an IFU(instruction fetch unit) 110 as long as the branch predictive logic 122 is not inhibited. Then the IFU 110 starts the fetch of a pair of instructions at the target address in a subsequent cycle. The enabling signal received from the logic 122 is inhibited when the branch resolve early signal produced by a branch resolution logic 200 is early asserted.
