Abstract: A rotary head type recording and/or reproducing apparatus is so arranged as to be able to record on and/or reproduce from a recording track on a recording medium a time code which is not synchronized with the revolution of a rotary head, whereby even when the revolution period of the rotary head is special, the edition of the recording medium can be made with high accuracy and a track exclusively required by the time code becomes unnecessary. Also, a surplus calculating circuit for calculating a surplus when a number is divided by a divisor is disclosed, in which the surplus can be obtained only by the addition without carrying out the division in practice. Accordingly, time necessary for such calculation can be reduced and the scale of circuit arrangement can be miniaturized.

Abstract: A multi-layer metallization method and structure that permits the use of sodium-ion contaminated tita­nium-tungsten (Ti:W) as a barrier metal with gold con­ductor metal on a silicon substrate, without signifi­cant degradation of device characteristics. After depositing the barrier and conductor metal layers, a layer of phosphorous-silicate glass (PSG) is anisotropically-etched to expose the field oxide and top surface of the conductor metal but leave PSG layer on each sidewall of the metallization structure. The circuit is then annealed at 400°C for 30 minutes. Then, an adhesion layer (Si₃N₄) and an insulative layer (SiO₂) are deposited over the metallization structure and field oxide, with the adhesion layer in contact with the top surface of the conductor metal and the gettering composition. The resultant circuit has a field threshold voltage shift comparable to devices made without a metal-ion-contaminated barrier layer and the resultant structure reliably retains the PSG layers in contact with the metallization sidewalls.

Abstract: A TTL buffer circuit (30) which is switched by an increasing or decreasing voltage input signal (Ii) at the same threshold, and which switches at increased speed. A bleed transistor (Q6) allows the phase splitter transistor base to begin charging before the bleed transistor (Q6) turns on. While the phase splitter transistor (Q3) is on, the bleed transistor current is limited to avoid interfering with operation of the phase splitter transistor (Q3). When the phase splitter control lead current is cut off, the phase splitter base capacitance is discharged rapidly through the bleed transistor (Q6), at the end of which the phase splitter and bleed transistors (Q3, Q6) stop conducting.

Abstract: A disposable plastic cartridge (54) contains three fine lightweight wire mesh collectors (84-1, 84-2, 84-3), each of phosphor bronze. One collector has an oxidized surface for collecting drug particulates. The other two have surfaces electro­plated with zinc to form a rough multi-fissured surface for trapping low volatility vapours. In use, a portion of a warm sample air stream is chilled and passed through the collectors in parallel for sample collection. Simultaneously part of the sample air stream by-passes the chiller (18) and is fed directly into a mass analyzer (50) for real time analysis. Next, both collection and real time analysis are terminated, and each collector is desorbed in sequence with a pulse of hot air which flows into the mass analyzer for sequential analysis.

IPC: G05F1/565
Filed: 1988-09-22
Abstract: This circuit is provided, in particular, for increasing the supply voltage of a Gunn oscillator for a short time. This is because Gunn oscillators are susceptible to oscillate at higher unwanted frequencies. For a reliable start of oscillation at low temperatures, a particular voltage reserve is required. However, a correspondingly high voltage increases the power dissipation of the Gunn element, which, at the same time, leads to a shortening of its service life. To solve these problems, the invention provides a circuit with a voltage regulator, which has connected in parallel with its input end a timing section, the output signal of which is supplied to a switching element. Between the switching element and the output of the voltage regulator, a capacitor is inserted for achieving the desired voltage increase, the voltage of which is superimposed as a voltage peak displaced by an adjustable time on the output voltage of the voltage regulator via the switching element. <IMAGE>

Abstract: The invention relates to a mechanism for cutting printed tape in a recording apparatus, the printed tape consisting generally of paper, cardboard or plastic wound on reels. In this arrangement, it is advantageous to keep the dimensions of such cutting mechanisms small so as to arrange them as closely as possible to the data printer, cutting mechanisms of various lengths with a working width adapted in each case to the width of the recording medium having to be produced in a variable and inexpensive manner for recording media of various widths in order to achieve the smallest possible structural size. This is achieved in that the mechanism consists of a profiled angular body with an outer receiving trough for the rotary cutter along an angle piece and with a second angle leg as a base part for receiving the motor in the angle between the two legs, it being possible to cut the profiled body to the desired passage width. …<IMAGE>…
