Title: Work pusher to horizontal shaft chuck face
Inventor: SUGINO YOSHIHIDE
IPC: B23Q7/04
Filed: 1980-02-29
Abstract: PURPOSE:To facilitate correct chucking in such a way that height in the level of a work center and its pushing point is determined to satisfy a certain prescribed formula, and eccentricity of a work and a chuck can be perfectly absorbed. CONSTITUTION:The height h from the work center to its pushing point can be defermined through the following formula, while taking into account the frictional force due to relative slidings between a work 30 and its pushing plate 21, and also the weight of work 30 at the time of absorbing eccentricity. Resolution of the balance of turning moment around a fulcrum (A) derives h>LW/F+(muL-d/2), (provided that L should be the work length, W be the work weight, mu be the frictional coefficient between the work and push-plate, and d be the work diameter), and also h<d/2 is applicable. With determination of h which should be derived from the both formulae, eccentricity of the work 30 and the chuck 31 can be perfectly absorbed, so that a correct chucking condition may be achieved.

Title: Time division multiplex access communication equipment
Inventor: UNO SHINTARO
IPC: H04J3/17
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To reduce the call loss of a call X by assigning a 2nd time slot for a call Y while reserving a 1st time slot for the call X on the occurrence of the call Y. SOLUTION: A demand assign processing section 23 retrieves an idle time slot depending whether a demand assign request signal received from a slave station by a reception section 21 is for a call X or a call Y. When an idle time slot is available, idle time slot information is written to a transmission reception register 22 and the demand assign signal is sent to a corresponding slave station via a control line and a transmission section 24. In order to assign a time slot of the communication opposite party slave station, similarly, a line assign signal, that is, a time slot assign signal is sent via the control line and an exchange. The opposite slave station uses the time slot of the designated communication channel after that to make communication with the slave station.  Thus, in the case of congestion of a multiple traffic, probability of call assignment is enhanced and the call loss rate is reduced.

IPC: G01M15/00
Filed: 1981-02-23
Abstract: PURPOSE:To efficiently detect transient knocking action in an ignition timing controller suppressing the knocking action, by giving a delay characteristic to the output of a noise detector circuit and comparing a level of said output with a level of the output of an acceleration sensor. CONSTITUTION:Generation of knocking causes output of an acceleration sensor 1 to pass through a frequency filter 2 and analog gate 3, and a knocking signal is largely overlapped to a mechanical noise, then output of a noise level detector 5 is delayed its response because of a rapid rise-up of the knocking signal, thus an output level in a delay circuit 13 is not changed. As a result, a pulse is generated in output of a comparator 6, and an integrator 7 integrates ulse to generated integrated voltage and shift the phase to a delay side through a phase shifter 8 and waveform shaper circuit 10. Further the output of the detector 5 is input to the comparator 6 through the delay circuit 13, then the comparator 6 increases comparison reference with delay at rapid increase of a load, thus knocking can be efficiently detected.
