Abstract: A process is disclosed for producing silicon nitride sintered bodies. The process comprises the steps of molding a formulated starting material of silicon nitride, firing a thus obtained molding to obtain a fired body having a desired shape, and then thermally treating the fired body in such an atmosphere that has an oxygen partial pressure higher than that in a firing atmosphere and suppresses a weight increment in oxidation to not more than 0.1 mg/cm<sup>2</sup>. Working may be done to obtain the desired shape of the fired body after the firing but before the thermal treatment. The process reduces defects due to differences of the intergranular phase between the surface and the interior of the body.

Abstract: This invention provides a rapid, noninvasive technique for quantifying the dynamic response of the autonomic nervous system (ANS) to perturbations it senses over a broad range of physiologically relevant frequencies. The technique involves two steps. First, a physiologic parameter sensed by the ANS is subjected to a broad-band perturbation as an input signal while a physiologic parameter modulated by the ANS is monitored as an output signal. Then, the transfer relation between input signal and output signal is determined. The computed transfer relation is then readily interpretable in terms of responsiveness of the various limbs of the ANS.

Abstract: For reducing the number of display data RAM chips to designate one pattern of a character pattern ROM which contains patterns of a large number of characters and needs a large number of bits to be designated, a clock signal whose cycle time is the same or less than the updating cycle time of the designating address data of the display data RAM is employed to address the display data RAM. Conventionally, the data of the display data RAM to designate the character pattern ROM is stored separately in different chips when the data length (bit number) becomes large. But, according to the present invention, the data is stored separately in one chip.

Abstract: Disclosed is a novel optical system for illuminating an object with effecting an increased irradiance in the peripheral area of the object. The optical system includes a light source, an entrance pupil for receiving light from the light source, an exit pupil for passing the light received to the object, and an optical axis which extends to the light source and the object, respectively, through the optical system, wherein the relationship among the incident height h to the entrance pupil, an illumination height H on the object and a changing rate (dh/dH) of the incident height and the illumination height is defined by a function, f(H)=(h/H)(dh/dH). The optical system is designed so as to satisfy the following formula in the peripheral area of the object: f(0)<f(H). The function f(0) is represented by: f(0)=[fa′/{(a′-f)b′}]², where a′ is a distance between the light source and the primary principal point of the optical system, and b′ is a distance between the real image of the light source and the object.

Abstract: An aperiodic mapping procedure for the mapping of logical to physical addresses is defined as a permutation function for generating optimized stride accesses in an interleaved multiple device system such as a large, parallel processing shared memory system wherein the function comprises a bit-matrix multiplication of a presented first (logical) address with a predetermined matrix to produce a second (physical) address. The permutation function maps the address from a first to a second address space for improved memory performance in such an interleaved memory system. Assuming that the memory has n logical address bits and 2 d  separately accessible memory devices (where d n) and a second address that utilizes n - d bits of the first address as the offset within the referenced device node. The procedure includes performing a bit matrix multiplication between successive rows of the said matrix and bits of the first address to produce successive d bits of the second address.

Abstract: A semiconductor field effect transistor is provided which permits controlling of the phase of carriers between a source region and a drain region formed in a first semiconductor layer. Such control can be used to modulate characteristics such as the electric conductivity and drain current of the transistor. To accomplish this control, a gate electrode (1) is formed over a portion of the first semiconductor layer (7) between the source and drain regions (8). The gate electrode (1) splits to form first and second branches at a first location adjacent to the source region. These first and second branches subsequently rejoin one another at a second location adjacent to said drain region. When a potential is applied to the gate electrode (1) it will produce first and second two-dimentional carrier conduction paths at a surface of the portion of the first semiconductor layer (7) under the first and second branches. An arrangement is provided for modifying the phase of carriers passing through the first conduction path relative to the phase of carriers passing through the second conduction path to produce a phase difference for carriers received at the drain region through said first and second conduction paths.
