Title: Method and apparatus for controlling throttle valve opening degree of internal combustion engines
IPC: F02D41/04
Filed: 1989-07-21
Abstract: An electronic control unit comprises a fuel supply con­
troller (6, 7) and a throttle valve opening degree con­
troller (2, 3, 7). The fuel supply amount controller 
estimates and calculates the amount of fuel being supplied 
in cylinders (13) with a real time. The throttle valve 
opening degree controller calculates a necessary opening 
degree so as to obtain a predetermined air-fuel ratio in 
accordance with a value resulting from the fuel supply 
amount controller. The fuel supply amount controller has a 
processing in which a fuel supply amount is corrected in 
accordance with an increase or decrease rate of an amount 
of fuel being adhered to an inner wall surface of an 
intake pipe (11). The throttle valve opening degree is 
controlled in accordance with a value obtained from the 
throttle valve opening degree controller as a control 
target value. A time lag in a follow-up for fuel is anti­
cipated in advance, a desirable target air-fuel ratio is 
maintained correctly and easily.

Title: Dual band/dual fov infrared telescope
IPC: G02B1/02
Filed: 1989-10-30
Abstract: A dual field of view telescope for operating in 
both the medium infrared spectral band from 3.8 to 5 
micrometers and the long infrared spectral band from 8 
to 11.5 micrometers. The telescope includes an

germanium lens A3 which serves to correct for residual 
axial chromatic aberrations in both IR bands due to its 
different dispersion characteristics in these two 
bands.

Patent EP-0333353-A3 (EP)
Title: Dual mode voltage reference circuit and method
IPC: G05F1/56
Filed: 1989-03-02
Abstract: A voltage reference circuit is described which is capable 
of providing either an internally generated voltage having a 
trimming capability, or an externally generated voltage, with 
the use of only two pins (2,4). The internal voltage is connect­
ed through an interrupt circuit (T2,T3,R4,R5,R7) to an input/­
output terminal (2), which can also receive an externally gene­
rated voltage. A trimming terminal (4) is used to apply trimming 
voltage signals to adjust the internally generated voltage. To 
convert from the internal (8,A1) to the external voltage source 
(20), an interrupt voltage is applied to the trimming terminal 
(4) which is outside of the normal trimming voltage range. This 
interrupt voltage actuates an interrupt circuit (T2,T3,R4,R5,R7) 
to interrupt the connection (T1) between the internal voltage 
source (8,A1) and input/output terminal (2), leaving the output 
terminal (2) available for the external voltage source (20).

circuit is provided with a first sum producing portion (36 to 41) 
activated in the co-presence of the two input bits of logic "1" 
level or logic "0" level and the low order carry bit of logic "1" 
level or logic "0" level to produce the sum bit, and a second sum 
producing portion (28 to 35) activated in the co-presence of at 
least one of the input bits and the low order carry bit different 
in logic level from the other bits to produce the sum bit 
opposite in logic level to the carry bit, so that signal 
propagation path is reduced in length, thereby achieving a high 
speed operation.

local dispersion of each element is expressed by: 
  
where n λ  is a refractive index at a center wavelength λ nm, 
n λ  + 5 a refractive index at λ + 5 nm, and n λ  - 5 a refrac­
tive index at λ - 5 nm.

Title: Laminated copper assembly
IPC: H01H1/10
Filed: 1989-07-27
Abstract: A laminated contact assembly for a circuit breaker with each individual contact assembly having a contact arm portion, carrying a movable main or arching contact and a stationary conductor portion. A flexible shunt connects the contact arm portion to the stationary conductor portion. Intermediate individual contact assemblies are provided with T-shaped slots for receiving square-headed fasteners. This avoids the need to drill and tap holes in the laminated contact arm assembly. Since the individual contact arm assemblies are fastened together, the square-headed fasteners disposed in T-shaped slots in intermediate individual contact arm assemblies is greatly reduced.

Title: Device for producing inserts for envelopes
IPC: B65H39/16
Filed: 1990-10-27
Abstract: For producing loose inserts (30) for envelopes, in the regions, in which the inserts (30), corresponding to the positional layout of the envelopes, are to have a distance from one another in production, there are made between neighbouring inserts (30) double cuts in the form of longitudinal cuts (25, 26) and/or in the form of transverse cuts (27, 28, 29) and thus cutoff parts (31) are cut free. The front transverse sections (39) in conveying direction (arrow 20) of the cutoff parts (31) are lifted out of the web (21) at the time of their cutting free and, after subsequent cutting free of the rear end of the cutoff part (31), drawn off. As a result, loose inserts for envelopes can be manufactured multiply lying next to one another and thus positionally accurately with high speed in such a manner that they can be transferred immediately subsequently between the cover layers of the envelopes. <IMAGE>

Title: Videorecorder with automatic still picture positioning
IPC: G11B15/18
Filed: 1990-11-16
Abstract: A video recorder with automatic still picture positioning senses during moving picture mode the levels of the waveform of the FM signal for successive fields and calculates a ratio from these levels. In still picture mode, the waveform levels are measured at respectively corresponding angular positions with respect to head switching pulses, and level ratios are likewise calculated. These actual level ratios are compared with set level ratios, as have been obtained from the moving picture level ratios in consideration of geometrical characteristics of the playback arrangement. From the deviations between level set values and level actual values, a respective tape position correction value is obtained. By constantly matching the level set values to the current ratios, it is ensured that the tape position correction values are appropriate for the current ratios. <IMAGE>
