Title: Control method of power supply device
Inventor: YAMAZAKI KIYOMI
IPC: H02M7/515
Filed: 1980-10-28
Abstract: PURPOSE:To realize the commutation to a thyristor that is receiving an adverse bias before the commutation, by temporarily inverting the polarity of the output voltage of an inverter device. CONSTITUTION:A gate signal is applied to a thyristor 63 at time t2, and at the same time a thyristor 21 is extinguished. Thus a diode 32 conducts to apply once the negative voltage to the primary winding of an output transformer 51. In this case, the polarity of the inter-HL voltage V0 of the transformer 51 becomes forward to the thyristor 63. As a result, the thyristor 63 immediately has ignition and the voltage V0 is turned into the commutation voltage. Thus the load current i2 which so far flows to the thyristor 61 is commutated to the thyristor 63. When this commutation to the thyristor 63 is over, the intermediate tap voltage VBL is applied to the load 8. When the thyristor 21 is ignited again an time t'2, the positive voltage is applied again to the primary winding of the transformer 51. Then the polarity of the load voltage is inverted to the positive side.

Title: Static-pressure air bearing pad
Inventor: SUGIYAMA SADAO
IPC: B23Q1/38
Filed: 1984-07-18
Abstract: PURPOSE:To improve bearing characteristic by forming the brached orifices into a plurality of grooves formed onto a bearing pad surface and making the pressure distribution on the bearing pad surface into symmetrical with respect to the center, thus suppressing the inclined floating-up. CONSTITUTION:The shallow groove 13 in the form of ''square with internal cross'' is formed on the pad surface 12 of a bearing pad body 11. The compressed air communicating to an outside compressed-air source is introduced into the bearing pad body 11, and blown-out from each orifice 16a-16d, and the bearing pad body 11 is floated-up by a minute gap by the pressure, and the bearing pad body 11 and the bearing surface 17 are supported in noncontact state. Therefore, even if the accuracy of the hole position of the above-described orifice 16 is inferior, and the distance from the center part 14 is a little shifted or incrined, the compressed air flows uniformly into the groove 13. Therefore, the air-pressure distribution on the bearing surface is made symmetrical with respect to the center, and the bearing pad is floated-up in stable state, without being inclined, and the superior bearing characteristic can be obtained.

IPC: H04L12/28
Filed: 1994-06-08
Abstract: PURPOSE:To provide a radio communication equipment capable of evading the collision of transmission while preventing the decline of transmission efficiency by providing a means for transmitting data when no carrier of another terminal is present while originating the carrier for the fixed number of times. CONSTITUTION:When transmission data are received from a data terminal 111 through a terminal communication part 12, the main control part 13 of this radio communication equipment 11 investigates whether or not the other terminal originates radio waves in a carrier sense part 16. Then, waiting is performed until the radio waves are interrupted when the radio waves are originated and the waiting is performed while sensing the carrier for the fixed period of time in the carrier sense part 16 when the radio waves are not transmitted. Then, when the other terminal does not originate the carrier during the time, the carrier is originated from a carrier origination part 15 and the data are transmitted. Thus, even when the collision detection windows of the plural terminals overlap, a situation that all the terminals become incapable of performing the transmission is eliminated and the transmission efficiency of the data is improved.

Abstract: PURPOSE:To attain copying with different modes and to obtain equal correcting capability at each mode by dividing each channel into plural groups and constituting one symbol from a remaining bit of a set excluding a sample set close to generated time. CONSTITUTION:A control circuit 41 outputting a control signal to selectors 37, 38 and a latch 36, registers 32-35, the selectors 37, 38 and the latch 36 produce one symbol from a remaining bit of plural words.
