Title: Cup type automatic vending machine
Inventor: KITA TOSHIKAZU
IPC: G07F13/00
Filed: 1988-11-17
Abstract: PURPOSE:To enable sanitary cooking by stirring mixed liquid of hot water and a raw material sufficiently without inserting a tool into the mixed liquid. CONSTITUTION:The hot water from a hot water tank 6 is injected into a cup 3 from a hot water feed pipe 4 with a gush and the raw material 8 is dissolved in the hot water while stirred by the hot waster. Further, the single hot water feed pipe 34 is displaced to 1st and 2nd positions P1 and P2 by a hot water feed pipe driving means 42. The hot water which is injected at the 1st position P1 flows upward along the side wall of the cup 3 from the bottom part of the cup 3 and the hot water injected at the 2nd position P2 flows rotating along the side wall of the cup 3, so that the raw material 8 is dissolved in the hot water while stirred by the two flows. Thus, the mixed liquid in the cup 3 can be stirred sufficiently without dipping any stirrer in the mixed liquid, so the sanitary cooking is enabled.

Title: Level setting device
Inventor: WATANABE SHINICHI
IPC: G05B1/01
Filed: 1986-12-09
Abstract: PURPOSE:To prevent a sudden change of a set level with the external noise by resetting the increase/decrease operations of a 3rd conversion means when a 1st level data changes at plural levels at the time of changing a 2nd level data. CONSTITUTION:A 1st conversion means 21 converts the set voltage of an initial level setting volume 10 into the 1st level data. A 2nd conversion means 22 converts said set voltage into the 2nd level data smaller than the 1st level data. A 3rd conversion means 23 increases and decreases the 2nd level data by a high/low level switch. When the set level changes by the high/low switch, the 1st level data obtained by the means 21 changes at plural levels. Thus the set level obtained by the 3rd conversion means 23 is reset fro the first time and changes again into the level data by the set output of the volume 10. Thus it is possible to prevent a sudden change of the water force level caused by the external noise.

Title: Method for combining three-dimensional sound field
Inventor: RICHARD DAVID KLEMOW
IPC: H04S5/00
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To efficiently supply an improved three-dimensional sound to a listener by supplying signals with controlled front and rear gains to the speakers at left and right in the front direction, left and right in the rear direction, controlling ratio of the front and rear signal gains as a function of the desired position of a sound source and performing crosstalk compensation in the front and rear. SOLUTION: Each gain of signals for a set of L and R channels to be generated by an arrangement filter for dual audition is controlled by a front and rear gain control means. These control signals are supplied to the speakers at left and right in the front direction, and left and right in the rear direction and each speaker is driven by a front and rear crosstalk cancelling (TCC) means. Linearity, cross attenuation area and a cross attenuation coefficient for each gain of the front and rear gain control means are controlled by the azimuth of a virtual sound source according to a predetermined simple cross attenuation algorithm. Thus, a superior three-dimensional sound source is obtained by using only four speakers which are arranged at the left and right in the front direction and left and right in the rear direction of ±30 degrees.

Filed: 1992-10-07
Abstract: PURPOSE:To reduce the work load of a program incorporating by recording voice superposing discriminating signals which instruct voice information superposing in plural voice information. CONSTITUTION:When voice superposing discriminating signals are included in the demodulated output of a demodulator 16, H level pulse signals are outputted to an OR circuit 29 from an S/H circuit 19. When voice superposing discriminating signals are included in the control data against an FM sound source 5, a PCM sound source 6 and a PSG sound source 7, H level signals are outputted to the circuit 29 from S/H circuits 22, 25 and 28. Thus, the circuit 29 outputs H level pulse signals to an AND circuit 33. When H level pulse signals from an S/H circuit 36 are taken into one of the input sides of the circuit 33, the circuit 33 outputs control signals, closes a switch 30 and the voice output level is reduced to one half. Therefore, the reduction control of the voice output level is performed by hardware.

Abstract: PURPOSE:To prevent the degradation of efficiency due to contention for the use of a bus line by providing a bus use state management means which monitors the use state of the bus to manage the use of the bus. CONSTITUTION:If it is necessary to transfer data between a memory 107 and peripheral devices 104, 105..., a CPU 101 uses the bus line to send the bus line use mode (occupied/non-occupied) for direct memory access (DMA) transfer and information (the memory address, the transfer direction, the transfer size, etc.,) required for actual DMA transfer to a bus state management means 102. Since the bus state management means 102 manages the present use state of the bus line, the means 102 receives the DMA transfer request from the CPU 101 to immediately determine whether the bus is used or the bus request is suspended. Thus, bus state management means 102 is provided to prevent a failure in DMA transfer.
