In response to detection of a note-on instruction, a CPU assigns a tone generating unit comprising two tone generating channels and sets tone color control data of the assigned tone generating unit into tone generator registers. The tone color control data includes a parameter common to the two channels. Once the CPU gives a tone generation start instruction to a tone generator, the tone generator accumulates a frequency number common to the two channels to thereby generate a progressive phase common to the two channels. Waveform readout section reads out left-channel and right-channel waveform data from a waveform memory on the basis of the phase and waveform selecting information of the left and right channels. Tone characteristics of the read-out left- and right-channel waveform data are controlled by a characteristic control section on the basis of a characteristic control parameter common to the two channels.

This invention provides a digital broadcasting receiving unit capable of achieving synchronization of time information between a base station and a receiving unit with reference clock without use of a crystal oscillator (VCXO) having a variable frequency. The crystal oscillator oscillates a clock of a predetermined fixed frequency. A variable digital dividing circuit divides a fixed frequency by a division ratio so as to change the division ratio. A system decoder detects reference time information from the base station. A reference counter generates time information of a receiving unit. A phase comparator detects a difference between reference time information and time information. A division ratio control circuit controls the change of the division ratio based on the difference. The reference counter generates time information based on a clock having a frequency obtained by dividing by the variable digital dividing circuit and feeds back time information to the phase comparator.

An imaging glass window and an illumination glass window which are opposed to each other define a sample chamber, and the sample chamber holds sample liquid containing particulates. Light from the particulates is magnified by a zoom magnifying glass via the imaging glass window, optical axis angle changing means and optical axis length changing means and imaged by a CCD camera. An image of the sample liquid is supplied to image control means, and the optical axis angle changing means is operated by the image control means to change an optical axis of the light from the sample liquid and shift an image of an intended one of the particulates in the sample liquid to the center a camera lens of the cameraeen. Concurrently the zoom magnifying glass is set at a required magnification by the control means.

An extracorporeal blood pump which comprises a pump housing having a pump chamber defined therein, and a rotary vane assembly accommodated within the pump chamber and including a substantially conical rotary pedestal having a base surface and a conical surface, a plurality of vanes each having radially inner and outer ends, and a driven shaft connected at one end with the base surface of the pedestal. The vanes are mounted on the conical surface so as to extend radially outwardly from an axis of rotation of the pedestal with the radially inner ends of the respective vanes being spaced a predetermined equal distance from an apex of the conical surface while substantially depicting a circle coaxial with the axis of rotation of the pedestal. Each neighboring members of the vanes are equally spaced from each other in a direction circumferentially of the pedestal. The base surface has a diameter of 30 to 55 mm enough to substantially cover a surface area of a bottom wall surface which partly defines the pump chamber and confronts the base surface of the pedestal, whereas each of the vanes is in the form of a generally rectangular straight plate extending at an angle of inclination within the range of 20 to 50 degrees relative to an imaginary line tangential to the circle delimited by the radially inner ends of the respective vanes. An extracorporeal blood circulatory device utilizing the blood pump of the type referred to above and comprising a control console accommodating a drive motor for the blood pump is also disclosed.

An image processing apparatus processes image data stored in a memory to thereby display an image on a display screen of a display unit under a control of a central processing unit (CPU). In one aspect of the invention, source data read from a source area of the memory are subjected to a rotation process and a logical operation and then converted to transfer data which will be written in a destination area of the memory by every word. In addition, first and last words within one line on the display screen are masked in accordance with predetermined first and second mask data. In another aspect of the invention, one of a wait mode and a not-wait mode is selected by wait control data outputted from the CPU. In the wait mode, the CPU is subjected to a wait state even in a memory read cycle. In the not-wait mode, the CPU is not subjected to the wait state normally in the memory read cycle. However, the CPU is subjected to the wait state in the not-wait mode while a reading operation of the memory has not been completed.

A porous ceramic body is prepared by dipping an organic foam having a three-dimensional network structure in a ceramic slurry to deposit a sufficient amount of the ceramic on the surface of the foam, moving an excess of the ceramic slurry contained in the foam to the intended peripheral region of the foam by exerting centrifugal force on the foam, thereby causing denser ceramic deposition in the peripheral region than in the other region of the foam, and then drying, solidifying, and baking to burn out and dissipate the foam and simultaneously sinter the ceramics.
