Patent EP-0171817-A3 (EP)
IPC: C25D3/56
Filed: 1985-08-16
Abstract: The present invention provides an aqueous composition 
and process for electrodespositing a layer of a ductile, 
strongly adhering, adsorptive and/or absorptive zinc coating 
or zinc coating comprising silicon and phosphorous on a 
metal substrate. The electrodeposition composition is pre­
parer by reacting metallic silicon and zinc with phosphoric 
acid and an alkali metal hydroxide in the ratio of between 0,4 
and 1,3 moles of alkali metal hydroxide per mole of 
phosphorus acid, and adjusting the solution to a pH of 1 or 
higher after completion of the reaction. The coating is 
deposited on the metal substrate by electrodeposition and 
comprises about 70 to 99.5% by weight of zinc, and about 0,1 
to 10% by weight of silicon, and about 0,5 to 20% by weight 
of phoshorus.  
     The resulting Zn/Si/P coating improves the resistance of 
the metal substrate to corrosion, wear, galling, stress 
corrosion cracking and cracking during mechanical forming 
operations. While essentially all metals of industrial import­
ance may be coated, this process is especially important for 
ferrous metals, steels, stainless steels, copper, aluminium, 
chromium and titanium.

IPC: G06F15/78
Filed: 1985-09-26
Abstract: A chip implemented in new technology is designed to in­
clude expandable levels of new functionality. The chip includes 
compatibility circuits which connect to a number of pins which 
are unused in the chip it replaces in an existing computer sys­
tem. The compatibility circuits connect to those internal parts 
of the new chip that contain the newly added or altered levels 
of functionality. The new chip is installed in the existing com­
puter system just as the prior chip. When so installed, the com­
patibility circuits enable the new chip to operate in the same 
manner as the replaced chip but at high speed and with im­
proved performance. When the new chip is installed in the sys­
tem for which it was designed, the compatibility circuits enable 
the chip to operate with a selectable level of new functionality 
at the same higher speed and improved performance.

Title: Method for processing as a frequency submitted measured value
IPC: H02P27/02
Filed: 1986-03-01
Abstract: Method for processing a measured value which is presented as a frequency and varies between mid values by forming a first electrical signal which is variable with the ratio of said frequency to a reference frequency, the signal in turn being in the same ratio to a specifiable electrical reference value. An essential feature of the invention is the use of the method in a speed regulation system for an asynchronous motor, in particular for an exhaust gas fan. The circuit for carrying out the method contains two operational amplifiers 51 and 55 connected to its various inputs, the two input pairs each being connected to a capacitor (47, 38) one of which is connected to chassis and the other to a voltage source which exhibits two extreme values for each cycle of the frequency of the actual-value sensor and is clocked between the two extreme values at the frequency of the actual-value sensor, the voltage range between the extreme values being settable but constant.

Patent EP-0253330-A3 (EP)
IPC: H04N5/357
Filed: 1987-07-10
Abstract: A solid-state image pickup device comprises a 
semiconductor substrate (1) of a first conductivity 
type, and a photoelectric cell including an impurity 
region (17,18) of a second conductivity type formed on 
the semiconductor substrate to produce a signal charge 
corresponding to the quantity of an incident light at a 
first junction surface between the impurity region of 
the second conductivity type and the semiconductor 
substrate. The device further comprises an impurity 
region (3) of the first conductivity type formed 
on the semiconductor substrate to effect isolation 
between the impurity regions of the second conductivity 
type, and a charge transfer unit (4, 5) for transferring 
the signal charge produced in the photoelectric cell. 
This device is characterized in that the impurity 
concentration of the impurity region of the second 
conductivity type is high in the vicinity of at least a 
portion of a second junction surface between the 
impurity region of the second conductivity type and the 
impurity region of the first conductivity type and is 
low in a range spaced from the second junction surface. 
With the device thus configured, under a highly 
reverse-biased condition due to the charge 
transportation, the high concentration portion of the 
impurity region of the second conductivity type is 
depleted, and under a low reverse-biased condition at 
the time of the charge accumulation, the high 
concentration portion is placed in a non-depleted 
condition. This permits the junction capacity at the 
time of the charge accumulation to be large, 
thus enabling realization of a solid-state image 
pickup device having less afterimage.

Title: Control valve device
IPC: F15B13/043
Filed: 1988-07-16
Abstract: Control valve devices, in particular for antilock device on pneumatically operatable vehicle brake systems, have a controllable inlet valve (47, 2) and a controllable outlet valve (9, 10). A pressure medium output chamber (3, 7) can be connected via the inlet valve (47, 2) to a pressure medium intake chamber (48, 50) and via the outlet valve (9, 10) to the atmosphere. 
<??>Since, in normal operation (uncontrolled operation), the reduction in pressure in the pressure medium output chamber (3, 7) occurs via the inlet valve (47, 2) and the pressure medium intake chamber (48, 50), the reduction in pressure is considerably delayed. 
<??>In order to overcome this disadvantage and to shorten the times taken for the reduction in pressure, the pressure medium intake chamber (48, 50) is subdivided into a first sub-chamber (48) connected to the inlet valve (47, 2) and a second sub-chamber (50) connected to the pressure medium intake (39), as shown in fig.1. The first sub- chamber (48) and the second sub-chamber (50) can be connected to one another via an additional valve device (38, 42) designed as a non- return valve directable onto the first sub-chamber (48) into the open position. 
<??>By this measure it is ensured that in the event of a reduction in pressure the return flow of pressure medium from the pressure medium output chamber (3, 7) occurs not via the pressure medium intake chamber (48, 50) but via the outlet valve (9, 10) directly into the atmosphere, thereby resulting in an accelerated reduction in pressure in the pressure medium output chamber (3, 7) and hence in the consuming unit.
