Title: Fluidized-bed classifier
Inventor: MITSUDA YOSHIHIRO
IPC: B07B7/00
Filed: 1997-03-28
Granted: 1997-10-01
Abstract: A fluidized-bed classifier has a vessel (20) defining a space divided into an upper fluidized-bed chamber (22) and a lower gas chamber (23) by a perforated dispersion plate (21) having the shape of a funnel. Rising currents of a gas, such as air, are blown through the dispersion plate (21) into the upper fluidized-bed chamber to produce a fluidized bed of a particulate material over the dispersion plate. The lower gas chamber (23) is divided into a first gas chamber (23a) and a second gas chamber (23b) by a partition plate (29). The gas is supplied into the first air chamber (23b) so that rising gas currents of a velocity necessary for fluidizing coarse particles contained in the particulate material fed into the vessel are blown from the first air chamber (23a) through the dispersion plate (21) into the fluidized-bed chamber. The gas is supplied into the second air chamber (23b) so that rising gas currents of a velocity lower than the velocity of the rising gas currents blown from the first air chamber (23a) into the fluidized-bed chamber (22) are blown into the fluidized-bed chamber so that coarse particles contained in the particulate material are not fluidized and does not flow together with fine particles into a fine particle discharge chute (28).

Title: An oscillator based tamperproof precision timing circuit
Inventor: MCALLISTER PAUL
IPC: H03L1/00
Filed: 1997-08-15
Granted: 1999-07-11
Abstract: An oscillator that has a substantially-constant t voltage source configured such that it does not require the voltage source to be tuned to a particular voltage to oscillate a particular frequency. The oscillator has greater precision and reliability since the inputs of the comparator are periodically switched to reduce the effects of the comparator bias and to equalize the voltage stresses on the inputs of the comparator. Greater precision is also achieved through the use of a discrete resistor and discrete capacitor to define the frequency of the oscillator. The present invention provides an oscillator and method to generate a periodic signal that is tamperproof because the circuitry that defines the period is either integrated onto the integrated circuit or contained within the package containing the integrated circuit. The oscillator may be used as a frequency reference in a speed governor circuit that speed governor may be included in an integrated circuit such that the speed governor disables a functional block of the integrated circuit when the clock frequency exceeds a frequency limit.

Title: Bitline load and precharge structure for an SRAM memory
Inventor: PATHAK SAROJ
IPC: G11C11/41
Filed: 1998-01-22
Granted: 1999-11-11
Abstract: An SRAM monitors its WRITE/READ pin 77, and when the SRAM is in a read mode, initiates a first precharging scheme in which every complementary bitline pair ((BL1, BL#1; BL2, BL#2; BL3, BL#3; BLn, BL#n is directly coupled to Vcc via a first pmos transistor (Ld1, Ld1#; Ld2, Ld2#; Ld3, Ld3#; Ldn, Ldn#) which is permanently turned on, regardless of whether a memory cell is being read or not, and both true and false bitlines in every complementary bitline pair are coupled together via a second pmos transistor (Eq1, Eq2, Eq3, Eqn) as long as the SRAM remains in a read mode. When in a write mode, a second precharging scheme is initiated, causing the second pmos transistor to be turned off and only the first pmos transistors remain active. The termination of the write mode activates a third precharging scheme which causes all the bitlines, both true and false, within the memory array to be momentarily shorted together (S1, S2, Sn-1).

Filed: 1998-03-20
Granted: 2000-07-11
Abstract: This is a voltage buck-and-boost power supply unit which raises/lowers the voltage without an iron core type transformer. It consists of a primary capacitor connected between the anode and cathode of a rectifier. The input low current high voltage AC current is rectified. The multiple secondary capacitors are connected between the positive and negative poles of said primary capacitor in series via the positive and negative switches. And the conductive elements of positive and negative poles for the secondary capacitor are respectively connected to the positive and negative output end. The output ends of the positive and negative poles are parallel in order to amplify the input high voltage low current to low voltage high current for output. Thus, the use of a conventional transformer with heavy iron core and winding is avoided.

Title: A method for forming a textured polysilicon layer, a substrate processing apparatus used to implement this method, and a semiconductor memory device
Inventor: SAKAI SUMIOI
IPC: C23C16/56
Filed: 1998-10-12
Granted: 2000-08-21
Abstract: To fabricate a capacitor with increased charge storage capacity and more stable characteristics by forming a polysilicon layer with a textured shape such as HSG on the surface of a substrate while doping it with a sufficient quantity of dopants, thereby achieving increased memory capacity. A second amorphous silicon film 93 with a low phosphorous concentration of no more than 1*10<20> cc<-1> is formed on a first amorphous silicon film 92 with a high phosphorous concntration of 1*10<20> cc<-1> or more, after which the films are subsequently annealed in vacuo. Before the crystallization proceeding from within the first amorphous silicon film 92 reaches the surface of the second amorphous silicon film 93, the silicon atoms at the surface of the second amorphous silicon film 93 migrate, thereby forming a texture at this surface. Since the resulting polysilicon layer 94 has a texture formed in  its surface, the effective surface area of the capacitor increases and the memory capacity is increased. Also, the device characteristics are stabilized since it is doped with a sufficient quantity if phosphorous.
