Inventor: BILZ GEORG
IPC: B22D15/02
Filed: 1990-07-25
Abstract: ABSTRACT     Low  pressure  chill  casting  method for casting metal cast components.        A low pressure chill casting method for  casting  metal components  such  as cylinder heads or engine blocks o combustion engines or the like, which  cast  components have  wall  portions  which  are  locally predominently thinner than in their other regions.  In  this  method, by  means  of gas pressure, liquid metal is  forced from a melt container through a riser   tube  into  a mold. According  to  the  invention,  the mold is so arranged that therein the  thicker  wall portion  of  the  cast component  is  cast upwardly remote from the gating and the thinner wall portion  is  cast  downwardly  in  the vicinity   of   the gating,  the  liquid  metal  being introduced at or near the lower region of the  mold  in the  vicinity  of  the  gating  into  the  mold  cavity region  forming  the  thinner  wall  portion.   In this connection, liquid metal can be  introduced  through  a base  runner  at a plurality of gating positions to the lower region of the mold lying in the vicinity  of  the gating   into   the  mold  cavity  region  forming  the thinner wall portion of the cast component.

Title: Method for manufacturing an ink jet recording head and a recording head manufactured thereby
Inventor: MASUDA KAZUAKI
IPC: B41J2/14
Filed: 1992-01-17
Abstract: A method for manufacturing an ink jet head, which is provided with discharging ports, ink passes conductively connected to the discharging ports, and energy generating elements for generating energy to be utilized for discharging ink, comprises the processes of giving hydrophilic property to the side of the discharging port formation plane of a work piece for constructing the discharging ports, forming an intermediate layer having a coupling agent containing Si on the plane to which the hydrophilic property is given, and forming a water repellence layer on the upper layer of the intermediate layer. Then, after machining the discharging ports by irradiating a pulse laser onto the plane of the discharging port formation member having the water repellence layer, the hydrophilic by-product generated in the vicinity of the discharging ports when the discharging ports are machined is removed to recover the water repellency around the discharging ports, thereby to enable the prevention of the adhesion of ink thereto. Hence preventing the degradation of the printing quality.

Title: Method of on-board detection of automotive catalyst degradation
Inventor: HAMBURG DOUGLAS R
IPC: F02D41/14
Filed: 1991-03-27
Abstract: Abstract of the Disclosure A method of on-board detection of the degradation of an automotive catalyst which receives the emissions from an engine placed in a closed-loop feedback control with an A/F characteristic sensor immersed in the emissions.  The method comprises: (a) artificially modulating the frequency and/or amplitude of the control for a predetermined burst period; (b) sensing an A/F characteristic by an independent sensor substantially immediately downstream of the catalyst at events prior to and during the burst period; and (c) determining if there is an absence of a substantial change between events in the independently sensed A/F characteristic, thus indicating a degraded catalyst.  The artificial modulation changes the oxygen exposure of the catalyst during a short catalyst interrogation period in a manner to magnify the oxygen absorption characteristic of the noble metals within the catalyst.  The artificial modulation may comprise a frequency change of a fixed uniform increase, such as 2-3 times the normal limit cycle frequency of the engine control, preferably about 2-4 Hz, or may comprise a variable change of frequency or amplitude such as ramping with or without steps or interruptions.
