Filed: 1990-09-20
Abstract: PURPOSE:To enable large timbre variation with a small circuit scale by varying the amplitude of a musical sound waveform, which is divided by frequency bands and stored, by the frequency bands and composing a musical sound by addition. CONSTITUTION:A band waveform generation part 1 which includes a waveform memory generates musical sound waveform data which are divided by the frequency bands and a band waveform amplitude coefficient generation part 2 generates band waveform amplitude coefficients by key depression KD, etc. The band waveform amplitude coefficients La - Ld correspond to the band waveforms Sa - Sd generated by a band waveform generation part 1, a multiplier 3 multiplies the band waveforms by the band waveform amplitude coefficients to determine the amplitude of the respective band waveforms, and an adder 4 adds them to generate a musical sound. Consequently, when each band waveform amplitude coefficient is varied, the frequency spectrum of the composed musical sound varies and the timbre of the musical sound varies. A multiplier 6 multiplies the composed musical sound by an envelope signal generated by an envelope generation part 5 to generate the target musical sound.

Filed: 1993-10-08
Abstract: PURPOSE:To surely hold a sheet material bundle carrying member at fixed position without raising the temperature of a pulse motor by executing the ON and OFF control of the application state of a driving signal to the pulse motor. CONSTITUTION:A driving circuit 106a is connected to a stopper sliding motor 106 (composed of the pulse motor)'via driving signal conductors L1-L4 and analog switches ASW1 and ASW2. They are connected to the side of (a) when a switching signal outputted from a CPU 201 is in ON state and the side of (b) when the switching signal is in OFF state. When the motor 106 is used as a drive source driving a bundle carrying member of this kind, the CPU 201 decides the carrying mode of a sheet material and switches the making/ breaking of the switches SW1 and SW2 to execute the switching control of the connection of the driving signal conductors as the winding wire of the motor 106. Thus, it is unnecessary that a driving current to the motor 106 is always applied and a sheet bundle carrying means can be held at the fixed position with the holding torque of the motor 106.

Title: Lead frame for semiconductor device
Inventor: HARA AKITOSHI
IPC: H01L23/50
Filed: 1991-10-01
Abstract: PURPOSE:To conform a substrate pattern pitch to an outer lead pitch and reduce the generation of defective soldering by adopting a constant shrinkage correction value per unit when the ratio between a long side and a short side of a planar rectangular-shaped resin sealing section is identical to each other. CONSTITUTION:A lead pitch of an outer lead 2 is corrected on a lead frame in consideration of its shrinkage produced when resin is sealed. Even in the case of a semiconductor device having a planar rectangular-shaped sealing section 8 which is different in size, constant correction is available per unit, if the ratio between its long side and short side of the sealing section is identical to each other, thereby producing a lead pitch of the formed outer lead 2, which is identical to an initial design value. It is, therefore, possible to design the lead frame without measuring shrinkage induced by thermal shrinkage. This construction makes it possible to solder an outer lead formed in a specified pattern without causing a positional deviation when a semiconductor device is soldered with a board or the like.

IPC: G05B19/05
Filed: 1994-10-19
Abstract: PURPOSE: To provide a data communication equipment capable of accurately measuring a period when a communication line is in a standby state and accurately controlling the transmission timing of data. CONSTITUTION: Terminal o M and S detect the data inputted to a data input terminal Sin in synchronism with a communication speed, detect the potential of signals inputted to a port PO with a predetermined sampling interval and judge whether or not start bit data are received. When the potential of the port PO is a first potential, a control circuit 2 performs a timing operation and times the period when the communication line K is in the standby state. The timing operation is reset at the timing of receiving top bit data for indicating the end of byte data and the timing operation is not performed after the reception timing of the start bit data.  Thus, even when a data communication speed is relatively slow and the relatively long period of being the first potential continues during one byte data, the period is not recognized as the standby state and the timing operation is not performed.
