Abstract: A clamping assembly for releasably holding toolholder having a shank includes a tool support member having a bore extending along a longitudinal axis.  A locking means is disposed in the axial bore for securing the toolholder to the support member.  The locking means includes a lock rod having first and second contact surfaces mounted in the support member. The lock rod moves along the longitudinal axis between a locked position and a release position.  A wedge rod is mounted in the support member for reciprocal movement along an axis angularly disposed with respect to the longitudinal axis.  The wedge rod has first and second wedge surfaces which incline in parallel fashion from opposite edges of the wedge rod.  First and second force transmitting elements are interposed between the wedge surfaces of the wedge body and the contact surfaces of the lock rod.  When the lock rod is moved in first direction, the first force transmitting element is moved outward with respect to the transverse axis into contact with the first support surface and pushes the lock rod towards a locked position.  When the wedge rod is moved in a second direction, the second force transmitting element is moved outward with respect to the transverse axis into engagement with the second contact surface of the lock rod and moves the lock rod towards a release position.

Filed: 1991-03-06
Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE    The life characteristics of an electron tube cathode in the operation at a high current density are enhanced.  A metal layer of not more than 2.0 µm thick is formed on a base containing nickel as the main ingredient and a reducing agent such as silicon and magnesium by depositing tungsten by an electron beam under heating in a vacuum.  The base is heat treated in a hydrogen atmosphere at 800 to 1,100°C.  An emissive material layer containing an alkali earth metal oxide and 0.01 to 25 wt% of a rare earth metal oxide, the alkali earth metal oxide containing at least barium oxide, is formed on the metal layer. the life characteristics of the cathode especially during the operation at a high current density such as not less than 2A/cm2 are greatly enhanced.

Title: Pll frequency synthesizer
Inventor: NORIMATSU HIDEHIKO
IPC: H03L7/18
Filed: 1991-04-19
Granted: 1996-04-23
Abstract: A phase locked loop (PLL) frequency synthesizer capable of switching the output frequency thereof at high speed. The frequency synthesizer has a second phase/frequency comparator and a second variable frequency divider in addition to a first phase/frequency comparator which is included in a PLL. The synthesizer switches over the time constant of a loop filter by the output of the second phase/frequency comparator, i. e., independently of the PLL which is responsive to the output of the first phase/frequency comparator. As a result, the time constant of the loop filter is switched over at an advanced timing to thereby reduce PLL tuning time.

Title: Detection system for abnormal cable connections in communications apparatuses
Inventor: YAMAGUCHI MASARU
IPC: G01R31/04

Granted: 1998-02-03
Abstract: In a communication apparatus in which a first level unit, a second level unit and a third level unit are hierarchically arranged and these units are connected to one another by multicore cables, one of the many cores of each multicore cable is used as monitoring core, and the first level unit sends out to each monitoring core a probe signal generated by sampling the digital signals supplied via the individual cores of the multicore cable and multiplexing them on a time-division basis.  The second level unit compares each of these probe signals and a string of signal samples supplied via the multicore cable corresponding to this probe signal, generates a faulty connection indicating signal in response to any discrepancy between them; generates, similarly to the first level unit, a probe signal for detecting any faulty connection between the second level and third level units; multiplexes these signals on a time-division basis; and inserts the multiplexed signal into the monitoring core to the third level unit.         The third level unit, on the basis of the probe signal for this signal supplied via the monitoring core, can display a faulty connection signal both for each multicore cable and for each individual core.

Granted: 1999-04-20
Abstract: Control of the self-testing of a plurality of elements (12 1 -12 m), each having a Built-In, Self-Test (BIST) capability, and arranged in one or more groups (14 1 -14 n), is carried out by a network (16) of one or more standard BIST resource interface controllers (SBRICs 18 1 - 18 n). Each SBRIC in the network controls the self-testing of the elements in a separate one of the groups in sequence by broadcasting a test command to the elements in parallel which, in response, generate test signatures stored by the SBRIC. The SBRICs in the network are coupled in series in daisy chain fashion to enable the test signatures stored by the SBRICs to be concatenated for easy retrieval by shifting out the test signatures therefrom, using a technique such as boundary scan.

Filed: 1993-10-06
Granted: 1995-06-27
Abstract: A towel protector includes a waterproof inverted bag provided with a suspension grommet for suspending the bag from a golf cart or the like. Another grommet in the wall of the bag allows passage of a towel suspension cord. The exterior part of the cord is provided with a spring loaded toggle abutting against the grommet.

Abstract: The present invention provides an apparatus (10) for determining a desired parameter of the motion of an object. The device (10) can be used to calculate the estimated carry distance of a golf shot. The golfer (16) uses a keypad (26) to enter the club (14) bating used and the units of measure desired for the output display (24). A Doppler radar system (34) is employed to illuminate the ball immediately after it has been hit. A reflected signal is detected and difference pulses are generated, having a frequency which is proportional to the velocity of the ball. The microprocessor is used to calculate the carry distance by relating the average period of the difference pulses to a projected carry Distance through empirically determined data. The carry distance can be displayed on the device (10) or on a remote display, and/or can be stored in memory for later recall or transmission to an external computer (118).
