Abstract: SEPARATE FONT AND ATTRIBUTE DISPLAY SYSTEM             Abstract of the Disclosure A  method  and  circuitry  for  using  two  buffers containing video display information is shown.   One buffer contains character mask or dot image information, while the other buffer has two portions, foreground and background, which store attribute information.  In non-compatible write operations attribute information stored in registers is written to the attribute buffers when mask information is written to the first buffer.   In compatible  write  operations  the  attribute  value  is written to the foreground attribute buffer and zero is written to the background buffer, while an OR'ed value of the attribute value is written to the first buffer. In non-compatible read operations the value in the first buffer may be obtained or a CRC values may be generated on the entire character cell.   The CRC value can be compared  with  similar  CRC  values developed  on  the character mask of interest to determine if a character is  present  in  the  cell.    In  compatible mode  read operations the value in the foreground or background buffer is selected based on the value in the first buffer.  In display drive operations a similar selection is made and the value supplied to the circuitry driving the display.

Abstract: A  method,  and  devices  produced  therewith,  for improving  the flatness  of  etched  mirror  facets  of integrated  optic  structures  with  non-planar  stripe waveguides such as ridge or groove diode lasers or passive devices like modulators and switches. The curvature in the mirror  facet  surface, occurring  at  the  edges  of  the waveguide due to topographical,  lithographical and etch process   effects,   that   causes   detrimental   phase distortions, is avoided by widening the waveguide end near the  mirror  surface  thereby  shifting the  curved facet regions away from the light mode region to surface regions where curvature is not critical.

Title: Method and circuit for recovering a logic signal from a band limited signal channel
Inventor: SCOTT STEPHEN
IPC: H04N5/93
Filed: 1990-06-11
Abstract: ABSTRACT OF THE DISCLOSURE      A method and circuit for recovering from a video signal a digital Vertical Interval Time  and Control Code  (VITC)  signal which has been distorted in  the recording process.  The video signal is passed through an appropriate high pass  (differentiating)  filter to remove all but the narrow spectrum associated with the rising and falling edges of the NRZ modulated VITC signal.   Optionally,  the  signal may be  low-pass filtered to improve noise immunity and remove any chroma or burst frequency components.   The resulting output signal is a separate  series of positive  and negative pulses with an average DC value of zero. These pulses correspond to the rising and falling edges of the original VITC signal, are detected and used to reconstruct the original VITC signal.   The positive pulses are delayed and then used to set a flip-flop while the negative pulses are used to reset the flip-flop.  The output of the flip-flop will substantially correspond to the original VITC signal.

Title: Housing shell for an in-the-ear hearing aid and method and apparatus for manufacturing the same
Inventor: HERMANN DIETMAR
IPC: H04R25/00
Filed: 1990-07-24
Abstract: ABSTRACT OF THE DISCLOSURE           A positive ear mold is processed to the desired size, equipped with a core in the proximal region, dipped in wax and placed in a container in which casting material for a negative form is filled.  After the ear mold has been taken out and the core has been removed, a flexible sliver is drawn into the negative form.   The sliver is laid out along the inner wall of the negative form prior to casting, and subsequently, the material for the housing shell is filled into the negative form.          After a brief polymerization time, the excess material is emptied out and after it has hardened, the housing shell is removed from the negative form.  By pulling a sliver insert out of the channel molded in the housing shell, one obtains the housing shell having a vent molded therein.

Title: Semiconductor device
Inventor: SHIGA NOBUO
IPC: H01L21/3205
Filed: 1990-08-21
Abstract: ABSTRACT OF THE DISCLOSURE   In a semiconductor device used in a light reception circuit or the like, a wide receiving bandwidth of a reception signal and a high receiving sensitivity are desired.  However, when the resistance of resistor of a signal receiving section is increased to improve the sensitivity, the receiving bandwidth is narrowed.  In addition, when the capacitance of a capacitor for removing a direct-current component of the reception signal is increased to increase the receiving bandwidth, the floating capacitance present in the DC cutoff capacitor is increased.  As a result, the receiving bandwidth is not increased.  For this reason, according to this invention, a second  conductive pattern is formed to be electrically insulated from a first conductive pattern set at a common reference voltage for the device, a metal film formed on the back side of the semiconductor chip is fixed to the second conductive pattern, and the voltage of the DC cutoff capacitor is transferred to the second conductive pattern.  Therefore, a variation in voltage of the capacitor is equal to a variation in voltage of the second conductive pattern underlying the capacitor, and there is almost no floating capacitance present in the capacitor.          The capacitance of the DC cutoff capacitor and the resistance of the resistor of the signal receiving section can be set to be large.

IPC: B29C45/17
Filed: 1990-12-20
Abstract: An arrangement introduces a metered volume of gas into a cavity filled with a melt of plastic. The cavity is defined by an injection mold for producing a hollow plastic body and the injection mold has an injection channel for introducing the molten plastic into the cavity. The arrangement includes a gas-injection nozzle assembly having a housing mounted in the mold and a member displaceably mounted in the housing so as to be movable between a first position and a second position located in spaced relationship to the injection channel. The housing and the member conjointly define a forward end portion of a nozzle assembly facing into the cavity at a region of the cavity spaced from the injection channel. A conducting channel in the forward end portion conducts the gas into the cavity when the member is in the second position. The conducting channel defines a gas-discharge opening for discharging the gas into the cavity.      The gas-discharge opening is freely projected approximately into the center of the region at which the nozzle assembly is located to thereby discharge the gas when the member is in the second position thereof and while the melt is injected into the cavity. A method of introducing the gas is also disclosed.
