Title: Assigning device in electronic musical instrument
Inventor: OKAMOTO KATSUNORI
IPC: G10H1/057
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To truncate a musical sound generating instruction means for generating an auditory small musical sound by selecting the musical sound generating instruction means to be truncated according to the function value corresponding to the tone color of a musical sound. SOLUTION: A sound source 30 has a plurality of musical sound generating channels (voices) for generating musical sound signals corresponding to the pressing of a keyboard 18. A CPU 10 calculates the level and time of ADSR(A: attack, D: decay, S: sustain, R: release) of a waveform envelope from the note number and velocity when a new musical sound generation instruction (note-on) is inputted by the key pressing operation of the keyboard 18. The waveform of the truncate envelope is properly set according to the tone color of the musical sound generated every voice, and it has a prescribed function value. The voice in which the current level that is the level in the present processing time of the waveform envelope is the smallest is selected as the voice to be truncated.

Abstract: PROBLEM TO BE SOLVED: To permit address information transfer on a bus for data transfer by dividing a direct memory access(DMA) cycle into a DMA cycle for reporting an address to be accessed in the next DMA and DMA for transferring data, and controlling the transfer of that DMA with the address. SOLUTION: A DMA request address and DMA request data from an external connection device 4 are supplied to a DMA transfer request circuit 3 and divided into address information, data information and data transfer direction. Concerning a DMA data transfer request using a bus 7, that DMA transfer request circuit 3 distinguishes whether the address requested by the external connection device 4 is to be transferred or write or read is to be performed to that address. Thus, an address data discriminate signal and a data transfer direction signal are respectively generated on signal lines 9, 10 and 11 together with the DMA request signal and outputted to a DMA transfer accepting circuit 2 and DMA transfer is controlled.

Filed: 1994-07-05
Abstract: PURPOSE:To facilitate performance verification to decide a program when an optional impulse response from a CPU is written in a memory, read repetitively, giving it to a waveform equalizer, and waveform equalization is controlled by the CPU. CONSTITUTION:A received television signal TV is given to a waveform equalization means comprising an adder 5 and a TF(transversal filter) 4 via a position (a) of a switch and to a timing signal generating circuit 1. A reference signal S is written in memories 6, 7 from the input and output of the waveform equalization means based on a timing signal TS from the circuit 1. The CPU 8 receives the signal S from the memories 6, 7 to obtain a tap coefficient of the TF 4, and it is written to the TF 4. A filter characteristic to cancel the distortion of the received signal TV is realized by the TF 4 and distortion is reduced by subtracting the signal from the television signal received by an adder 5. The correction is repeated to conduct waveform equalization.

Title: Information recording and reproducing system
Inventor: IIJIMA KATSUMI
IPC: G11B27/00
Filed: 1988-06-22
Abstract: PURPOSE:To enable a recording and a reproducing processings to be performed even when the sector size of a directory is different from that of data by executing the recording instruction and the reproducing instruction of the directory by a host computer via an SCSI. CONSTITUTION:A mode bit 11 is a bit to show whether an operation is a recording operation or a reproducing operation, and is constituted of two or more bits, and includes the function of a command to reproduce the next directory in case of performing the reproducing operation. When a directory command 10 is issued from a CPU, the mode bit of a byte 1 in the command 10 is confirmed, and the recording of the directory is performed when a mode bit 11 is set at 0. And the CPU judges the bit 0 of the mode bit when the bit 1 of the mode bit is set at 1. When a bit 0 is set at 0, a first directory is reproduced, and when the bit 0 is set at 1, the next directory is reproduced. In such a way, it is possible to perform recording and reproduction even when the sector size of the directory is different from that of the data, and to easily manage an optical card with several M bytes.

The fibers 2 and formas 3 are  stirred in a precipitated state in this way and rubber base latex is dosed thereto,  then the foams 3 are fixed to the fibers 2 and this is sheeted on paper screen. The  sheet made in this way is thermo- pressure formed for severl minutes at temperatures of 180 to 200 deg.C, then the water having infiltered in the foams 3 evaporates and  the diaphragm 1 for speaker is thus obtained.

Filed: 1988-06-22
Abstract: PURPOSE:To effectively decrease a speed change shock by suspending a feedback control of engaging transient oil pressure while anticipation-controlling it on and after considering the history up to that time, when the speed change final period is detected. CONSTITUTION:An engaging transient oil pressure control means inputs an engine speed, detected by an actual speed detecting means, and a rotary speed of a member, changing the rotary speed in a speed change execution in a friction engaging unit of an automatic transmission, when the speed change execution is started, an engaging transient oil pressure is feedback controlled in a manner wherein the member rotary speed is generated along a locus of the target rotary speed set in a decision means. When a speed change final period detecting means detects the speed change to be placed in the final period, a feedback control is suspended, while the engaging oil pressure on and after is anticipation-controlled considering a history of the engaging transient oil pressure up to that time correcting an oil pressure value of the speed change final period preset in a map. Thus surely decreasing the oil pressure in the speed change final period, a speed change shock can be effectively suppressed.

Title: Hand-written graphic transmission display system
Inventor: YOSHIZAWA KENICHI
IPC: H04L12/70
Filed: 1990-06-13
Abstract: PURPOSE:To reproduce the state of the input from the sender side with fidelity at a receiver side by providing a read controller receiving a signal of a timer of the same period of timer by which an input device fetches coordinate information and reading coordinate information from a reception buffer. CONSTITUTION:A data received from a non-real time transmission line 7 is stored in a reception buffer 4 through a transmission control section 3. On the other hand, a timer 6 giving a signal of a prescribed period to an input device 1 gives a signal of a same period to a read controller 8. Every time the read controller 8 receives a signal from the timer 6, the reception data whose validity is confirmed is read from the reception buffer 4 by one coordinate and the data is transferred to an output display device 5, in which the data is displayed. Thus, since an output display device 5 displays the data at a same period as the fetch of the coordinate, the state of the input is reproduced from the display at the receiver side with fidelity regardless of a delay in the transmission line.
