IPC: G01J1/44
Filed: 1987-10-29
Abstract: An apparatus for very accurately determining the 
concentration of a light-absorbing material contained in 
blood flowing through a tissue which does not require the 
use of highly accurate components such as A/D converters 
having large numbers of bits. The apparatus operates 
according the principle that light beams of different 
wavelengths are absorbed by different amounts when passing 
through the tissue at different portions of the blood 
pulsation cycle. A digitization technique is employed 
whereby when limit values of the detected analog signal is 
reached, the input signal to an A/D converter is reset and 
digital output signal appropriately scaled.

Abstract: An apparatus and method for spectrophotometric 
analysis of material in a moving process stream wherein 
the material is directed into an observation chamber 
within a sample cell and exposed to a radiation beam 
suitable for spectrophotometric purposes. A radiation 
source and a radiation detector are contained within a

cell. Mirrors are positioned within the second 
compartment for diverting the radiation beam from 
passage through the material and for determining a 
reference spectrum within the same environment as the 
sample cell and directing the diverted beam to the 
radiation detector.

Abstract: A system for making alignment marks in a semiconductor 
for a wafer (10) etched in alignment with and bordered 
by an isolation level oxide (24). A silicon wafer has 
a film stack of silicon dioxide and silicon nitride. A

device region and leaving exposed the alignment mark 
positions. The wafer (10) is then etched to create the 
alignment mark pattern (trenches 32) in the wafer 
while the device region is protected by the resist

Title: Low current cmos translator circuit
IPC: H03K12/00
Filed: 1989-07-10
Abstract: A low current CMOS translator arrangement is disclosed that utilizes a low current inverting stage (102), having a peak current requirement, fed by a constant current source (104) at a supply node (+V) that also has a capacitor (106) coupled to it. This low current inverter (102) is useful for a number of applications, including generating a sinusoidal signal when it is coupled to a crystal. When one or more are cascaded and coupled to a square wave input signal, the arrangement becomes a low current translator that level-shifts, or translates, the input signal having a first voltage range to a translated square wave output signal having a second voltage range. In another embodiment called a low current squaring translator, a squaring stage is coupled between the low current inverter and a low current translator that includes one or more inverting stage.s This arrangement is able to achieve an output signal that maintains a precise duty cycle with low noise at a very low current.

Patent EP-0332475-A3 (EP)
IPC: H01M50/296
Filed: 1989-03-13
Abstract: A battery charger (12) accepts battery packs 
(14, 16, 18) of several configurations and size (number 
of cells). The common feature of the battery packs (14, 
16, 18) is (at least) one cell (124, 124 c ) housed on end 
and substantially coaxial with a specific terminal block 
(22, 22 a ). Terminal pins (158, 160; 248, 250) are 
shielded from external contact and engage the terminal 
blades (90) of a charger terminal assembly (88) on the 
floor (46) of a receptacle (20). Charger terminal 
assembly (88) is at one end of the receptacle (20) which 
is elongated so that it can accommodate a battery pack 
"nose" portion (130, 242, 180) with either one or two 
cells (124, 124 c ) housed on end and side-by-side. 
Upright side walls (36, 37) of the receptacle (20) 
support the battery pack (14, 16, 18). In the battery 
pack portion (136, 170, 182) outside the receptacle 
(20), cells (124, 124 c ) may be arranged in any 
configuration to suit tool or other requirements. 
Terminal blades (90) are normally biased away from their 
respective terminal apertures (60, 62) to minimized risk 
of accidental contact. Insertion of an elongated 
insulation member (166, 166′) displaces the terminal 
blades (90) to a position in which they contact the 
terminal pins (158, 160; 248, 250). Charging control 
circuitry, including means (118) for sensing battery 
temperature, is all contained in the battery charger 
(12), with a visible indication of charging condition 
being given by light emitting diodes (120, 121) and 
transmitted externally through optic tubes (72, 73). In 
assembly of the battery charger (12), accurate register 
of charger terminal assembly (88) carried on a printed 
 
 
circuit board (82), with corresponding terminal 
apertures (60, 62) in the floor (46) of the receptacle 
(20) is achieved through the mutual engagement of a 
tapered dowel (68) and mating hole (86) in these parts.
