Abstract: Apparatus for conducting thermogravimetric analysis continuously when sample weights are measured automatically in the case of measurement of a plurality of samples. A plurality of empty sample containers are transferred individually in succession from a tray to a thermobalance, where each container is weighed and a representation of the weight of each empty container is stored in a first memory. Then, a sample is loaded into each container in the tray and the loaded sample containers are transferred individually in succession from the tray to the thermobalance where each loaded container is weighed and a representation of the weight of each container is stored in a second memory. The weight of each sample is then determined based on the difference between the representations stored in the first and second memories.

Abstract: A thermomechanical analyzer for efficiently measuring the dynamic viscoelasticity of a sample piece. The analyzer is provided with a function generator, a stress applier, a strain detector, an analog-to-digital converter, a memory and a Fourier transform processor. The function generator generates a sine wave signal to induce a sine wave stress-strain response in the sample piece. This response is Fourier-transformed by the processor to calculate the dynamic viscoelasticity of the sample piece.

Abstract: A memory access control system is disclosed. In this system, a CPU, a low speed memory, a high speed memory and direct memory access controller (DMAC) are connected to a system bus. A high speed memory is connected through a local bus to the CPU. A control circuit is connected to the local bus, the system bus and the high speed memory. A bidirectional buffer is connected to the local and system buses. When the CPU accesses the high speed memory, the control circuit addresses the high speed memory and disables the buffer. As a result, data can directly be transferred between the CPU and the high speed memory. When the CPU accesses the low speed memory, the control circuit drives the system bus according to a protocol of the system bus, thereby to address the low speed memory and enables the buffer. As a result, data can be transferred between the CPU and the low speed memory, via a route of the local bus, the buffer and the system bus.

Abstract: In a computer system, a CPU bus cycle control section receives a bus cycle request (BC-REQ) to generate a system bus cycle request (SBC-REQ) and feeds back a ready notice (READY-a) to the CPU. A system bus cycle control section performs the bus cycle control in response to the system bus cycle request (SBC-REQ) from the control section and generates a ready notice (READY-b) to the CPU bus cycle control section. The computer system includes a timer for delaying the ready notice (READY-b), a selector for selecting one of the ready notice (D'READY) delayed by the timer and the ready notice (READy-b) from the system bus cycle control section and supplies the selected ready notice to the CPU bus cycle control section and a register for holding access control information including a recovery state bit FRDY and recovery time data (RDY3-RDY0) of the timer.

Abstract: A plurality of memory blocks, which includes a plurality of memory areas, each having a page number. Each of the memory blocks has a set number. A page controlling register stores mapping information and a page number of the memory areas. A mapping register stores mapping information including set information that indicates the set number of a memory block in which data supplied from a CPU is stored. A memory controller accesses the memory section in accordance with the mapping information.

Abstract: In a tone control device in a monochromatic tone display apparatus, when an intensity signal and at least one of the R, G and B signals is active, an AND gate generates a maximum tone level signal. A selector/adder having OR gates and resistors receives the maximum tone level signal and the R, G and B signals. When the maximum tone level signal is inactive, the selector/adder generates a tone level signal in response to the active state of the R, G and B signals. When the maximum tone level signal is active and all the R, G and B signals are inactive, the selector/adder generates a minimum tone level voltage. However, when the maximum tone level signal and at least one of the R, G and B signals is active, the selector/adder generates a maximum tone level voltage.

Abstract: A floppy disk drive interface circuit of the invention has a counter/selector for counting the pulse width of a window signal supplied from a voltage frequency oscillator. When a window pulse having a pulse width longer or shorter than a preset pulse width is input, counter/selector supplies a disable signal to AND gate 22. AND gate 22blocks window signal 12 from VFO2 being supplied to FDC 3.

Abstract: Phenolic novolak resins are produced from acetophenone, particularly by-product acetophenone obtained from the cumene process for manufacturing phenol, by the process of (1) reacting acetophenone with an aldehyde under alkaline conditions, and (2) reacting the product of step (1) with a phenol under acidic conditions. Phenolic resole resins are produced by reacting the product of step (2) with an aldehyde under alkaline conditions. The acetophenone modified phenolic resins are useful as a molding material, a felting or batting binder, a grinding stone binder, a foundry sand binder and an adhesive for timbers.

Abstract: Improved preparation of densified wood reinforced with a resole phenolic resin is accomplished by impregnating wood with a solution of the resin in the presence of about 0.6 to 4 parts of methanol, acetone, or mixture thereof per part by weight of the solids content of the resin under a pressure of about 10-50 Kgs/cm.sup.2 and thereafter drying and curing the resin-impregnated wood. The resultant product has an enhanced content of cured resin and greater bending strength than densified wood prepared by conventional resin impregnating techniques.
