Title: Information transmission system and method
Inventor: TOMURA MOTOHISA
IPC: H04N7/173
Filed: 1997-08-12
Abstract: PROBLEM TO BE SOLVED: To improve the quantity of information, when the data which are continuos in terms of time are transmitted by estimating the time needed for the end of transmission/reception of the specific data from the time spared for both transmitting and receiving devices and controlling the transmitting device to end the transmission/reception of the specific data. SOLUTION: The data on the unit quantity size-unit are transmitted iteratively to a client from a server for every unit time t- cycle. The client measures the time t- echo and t- recv needed for the standby for reception and reception of data in every unit time cycle and then notifies the server of these measured times, when the next cycle starts. The server measures the time t- send and t- read needed for the transmission of data and read of data in every cycle. Then the server calculates the time t- limit that is available for transmission of the unit quantity data, based on the notification data and the measurement data on the preceding cycle when a next cycle starts (S22) and transmits the unit quantity data within a tine t- limit (S25).  The unit quantity data are fractionated into (n) pieces of segment data of size- unit/n quantity, and a transmission (S31) and a pause (S34) of every segment data are repeated (n) times within the useable time t- limit.

Inventor: ARAI AKIFUMI
IPC: H02P6/08
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To simplify the configuration of a circuit which generates 6-channel three-phase switching signals by performing three-phase excitation at all times by turning on one of three channels of the three-phase switching signals at all times. SOLUTION: Signals A and B for driving a DC motor with brush are inputted to a rotation direction detecting circuit 6 provided to a control section 5, and the rotation direction signals 7 in the CW and CCW directions, are inputted to a motor drive control circuit 11, to which three-phase detecting signals UE, VE, and WE outputted from a Hall element 10 connected to a brushless DC motor 4 are inputted. Although six-channel three-phase switching signals 12 which are outputted in two directions from the control circuit 11 are supplied to a motor drive circuit 3 after the signals 12 are amplified via a preamplifier 13, the signals 12 can be excited in three phases when the signals 12 are turned on three channels by three channels at each electrical angle of the motor 4 at all times, by controlling the turning on/off of the signals 12 by means of the control circuit 11. Therefore, the motor drive control circuit 11 can be simplified markedly.

Filed: 1983-11-18
Abstract: PURPOSE:To obtain a magnetic recording medium excellent in running durability without large friction coefficient and shaving by providing crater form recessed parts having a specific value of average diameter at a specific density on the surface of a background layer in a magnetic recording medium. CONSTITUTION:On the surface of the background layer of the magnetic recording medium where the magnetic recording layer is provided on the surface of a nonmagnetic base, a filling agent and a binder are included on the other side and the background layer having a thickness of <=2mum, 10-1,000 per 10 square micron of crator form recessed parts having <=1.5mu of average diameter are provided. The average diameter of the crater form recessed parts is <=1.5mu and the depth is preferably 0.01mu-1mum at maximum depth. The craters play a role of lubricant pool and the continual lubricant effect is attained by providing the craters onto the background layer. If the average diameter of the recessed part of the craters exceeds 1.5mum, transfer is caused to the magnetic layer and adverse effect is given to the electromagnetic converting characteristic. Similarly, too much or too less number of the craters are injurious.

Title: Musical sound generation circuit
Inventor: MATSUZAKI YUICHI
IPC: G10H7/00
Filed: 1987-08-31
Abstract: PURPOSE: To generate a musical sound signal without requiring a complicated arithmetic circuit and its control circuit by introducing two D/A converters. CONSTITUTION: An amplitude value memory 1 is connected to a D/A converter (1st D/A converter) 6 for amplitude control and data of the amplitude value memory 1 are sent to the amplitude control D/A converter 6, which performs D/A conversion. When its output voltage is supplied as the reference voltage of a D/A converter (2nd D/A converter) 7 for waveform generation, the D/A converter 7 for waveform generation performs D/A conversion between a GND voltage and two reference voltages. Therefore, a waveform is generated by sending data of one cycle of the waveform to the D/A converter for waveform generation so that the value after the D/A conversion becomes equal to a desired waveform in time series. Consequently, a digital musical sound generator is obtained which is capable of output up to a high frequency range with the simple circuit.
