Abstract: After the separating grooves has been formed, the polycrystalline silicon deposited as bonded to the single crystal substrate as a supporting base, and the polycrystalline silicon layer ground and polished until the oxide film in the area other than the separating grooves is exposed, the present invention etches the polycrystalline silicon layer on the separating grooves with mixed acid composed of hydrofluoric acid and nitric acid until its thickness equals that of the separating oxide film and subsequently removes the oxide film in the area other than the separating grooves with hydrofluoric acid. As a result, the otherwise inevitable occurrence of projections of polycrystalline silicon can be precluded. When the dielectric-separation substrate obtained by the present invention is used in manufacturing a semiconductor device, therefore, the occurrence of particles due to the chipping of the projections of polycrystalline silicon and the breakage of distributed wires in the produced device can be prevented.

Abstract: A memory access scheme achieved using a memory address register and a register-indirect memory accessing mode eliminates write back collisions, long cycle time, and enhances system performance. During memory address generation operations, an arithmetic-logic unit (ALU) generates memory addresses from data in a general purpose register (GPR). Then, the memory addresses are written back to the GPR and a memory address register (MAR). During memory access operations, the MAR is accessed for the memory addresses to access a memory. Two approaches are provided. In a first approach, use of the MAR during the memory access operations is explicit. In a second approach, use of the MAR during the memory access operations is transparent. According to the second approach, a controller is provided to validate the MAR during the memory access operations.

Abstract: 2.1 The invention is based on a synchronisation method for a GSM mobile telephone. The synchronisation for a mobile telephone of this type must satisfy stringent requirements in terms of transmission reliability and accuracy and is intended to be implementable at minimum technical expense. 2.2 In the synchronisation method according to the invention, initial synchronisation, normal-operation synchronisation and final synchronisation take place during normal operation in the mobile telephone. The initial synchronisation is divided into rough frequency synchronisation, rough frame synchronisation and fine frequency synchronisation and fine frame synchronisation, whereas the normal-operation synchronisation comprises fine frame synchronisation with fine frequency synchronisation and data signal pre-processing, and the final synchronisation comprises rough frame synchronisation and fine frame synchronisation with fine frequency synchronisation. 3.

Abstract: A system monitors the stability of fats and oils especially having the capacity of simultaneous analysis of a multitude of samples making it convenient for use to monitor a production plant. A plurality of probes (20) made from a metal taken from a group consisting of nickel, chromium, rhodium, titanium and stainless steel have spaced parallel electrodes (38, 40) immersed in a liquid carrier (52) (deionized water) through which an effluent of heated fats or oils is bubbled. A common conductivity meter (24) responds to signals from each of the probes, in turn, for measuring the induction time of the fats or oils samples. The instrument features a power failure recovery system that utilizes a battery-power clock, so that short duration power failures do not cause a loss of data. A long duration power failure does not cause loss of data to the point of failure, however incomplete analyses are stopped.

Abstract: With closed woodburning stoves having a glass portion (4) in the stove door (2), there is a great problem that soot and condensate are deposited on the inner surface of the glass portion. 
     According to the invention, this can be prevented by mounting a heat exchanger directly above the door (2) on the front part (23) inside the fire box (19), and in such a manner that the air intake (21) takes place directly through a slot (7) in the front part (23). The heat exchanger is divided into an upper chamber (13) to which the inlet air (21) is led from outside, and a lower chamber (14) from which the heated and expanded air (24) is led out through a slot (15) at the front over the glass portion, the breadth and direction of flow of said slot (15) being adapted to suit the height of the glass portion (4) and the fire box (19). 
     The outflowing air is thus heated to a temperature of up to 250°C, and flows out at a speed which holds the glass portion (4) completely free of soot and condensate. It is also led to the combustion zone as heated primary air. This ensures a good combustion and a high degree of efficiency.

According to another aspect of the invention the shape of the dental prosthesis is such that near the edge of the prosthesis the cement layer is thicker than at some distance from said edge. Therefore the edge of the dental prosthesis is released from heavy forces.

Abstract: A weak pull-up disable method and mechanism therefor for use in association with a microcontroller incorporated in an integrated circuit. The weak pull-up disable mechanism is incorporated in the integrated circuit containing the microcontroller. The mechanism disables the weak pull-ups of I/O buffers of the microcontroller. The weak pull-ups serve to pull the voltage of the associated ports high. By so disabling the weak pull-ups, the need for a driver to sink the current when in input mode is eliminated. Elimination of the need for an external driver due to the weak pull-up disable mechanism reduces power consumption by the integrated circuit.
