Abstract: An extruding apparatus for producing a honeycomb structure having cell walls and a skin. The apparatus includes a die (10) and a mask (20). The mask (20) is of an annular shape of an inner diameter (D1) and is located on an annular recess formed by a taper surface (19) and an outlet end surface (18b) of the die. The mask (20) has a top surface (21), which is in contact with an outlet end surface (18b) of the die (10), so that the degree of the opening of feed holes (11a), (11b) and (11c) are controlled by the particular shape of the end surface (21). A change of the mask to the one as shown by a phantom line (30) allows the shape of the top surface to be changed from the one shown by (21) to the one shown by (31), which allows the degree of the opening of the feed holes (11a), (11b) and (11c) to be desirably controlled.

Abstract: An extrusion die for forming a honeycomb structure such as a catalyst carrier of a catalytic converter for internal combustion engines is provided. The extrusion die includes material inlet ports and latticed slits. The slits are formed in a die base and have first inner walls leading to an outer surface of the die base and second inner walls leading to the material inlet ports, respectively. Metal-plated layers are formed on the first inner walls of the slits to define outlets of the die and have the width smaller than those of the second inner walls of the slits, respectively. This die structure facilities easy extrusion of the honeycomb structure made up by thin honeycomb walls with a smaller extrusion resistance.

Abstract: An oxygen sensor has alumina porous layer on a surface of a solid electrolyte to cover electrodes and the alumina porous layer is simultaneously baked with the solid electrolyte. The alumina porous layer has baking contraction percentage which is the same range of the solid electrolyte. Alumina powder which is a starting material of the alumina porous layer includes 0.3 to 0.5 .mu.m of a 50% grain size, 0.4 to 1.1 .mu.m of a 70% grain size, and 0.8 to 4.0 .mu.m of a 90% grain size in a grain size distribution of weight integration frequency and further a specific surface area according to a BET method is approximately 8.5 to 11.0 m.sup.2 /g. It is preferable that the baking contraction percentages of the solid electrolyte and alumina porous layer are approximately 16 to 22%.

Abstract: An oxygen concentration detecting device has a solid electrolyte made of a partially stabilized zirconia on one face of which is formed a measuring electrode exposed to a gas to be measured and on the other face of which a standard electrode exposed to a standard gas. An oxygen concentration detecting device provided with a protecting layer covers the measuring electrode formed on the oxygen concentration detecting device on the face exposed to the gas to be measured, the protecting layer being made of a partially stabilized sintered material of a partially stabilized zirconia material having a specific surface area of not less than 3 m.sup.2 /g and not more than 6.4 m.sup.2 /g to which a divalent or trivalent metal oxide, such as yttria, is added.

Abstract: An oil-pressure warning apparatus for automobiles includes an oil-pressure switch which is turned on when the circulation pressure of engine oil drops below a predetermined level, an alarm circuit which provides an electrical path in response to the on-off operation of the oil-pressure switch, and a warning control circuit which energizes the alarm circuit when the oil-pressure switch is turned on and maintains the energization of the alarm circuit. Thus, even when the oil pressure switch fluctuates back and forth between its on and off positions, the warning lamp will not flash.

Abstract: A passive seat belt control apparatus includes a retractor for housing part of a seat belt. The retractor includes an arrangement for sensing acceleration and deceleration of a vehicle door and the speed at which the seat belt is pulled out from the retractor, and a mechanism for locking the seat belt. A solenoid operates to cancel the function of the retractor, and a door switch detects opening and closing of the vehicle door. A main control unit actuates the solenoid when the door switch detects that the door is open, and the main control unit includes an arrangement for continuously maintaining the solenoid operative for a predetermined time whenever the door switch detects that the door is closed after it has previously detected that the door is open.

Abstract: A diagnosis system has a diagnosis switch, and has a controller actuated by the switch for checking the operation of sensors and circuits and for lighting an alarm lamp in accord with a coded lighting signal, the number of times the alarm lamp is lit indicating the result of the diagnosis. The diagnosis switch includes a pair of diagnosis terminals which are similar to a pair of fuse terminals and are provided in a fuse box or in a joint box having a fuse box, and includes a spare fuse which can be inserted into the diagnosis terminals so as to produce a signal to the controller for starting the diagnosis.

Abstract: A polyolefin composition and the same especially used for producing vehicle exterior members which is excellent in softness, impact resistance, moldability, appearance, restorable property and so forth. The composition comprises 20 to 70% by weight of a crystalline propylene polymer (a); 10 to 50% by weight of a substantially amorphous .alpha.-olefin copolymer (b); 5 to 50% by weight of an ethylene-.alpha.-olefin copolymer (c) which is 0.860 to 0.910 g/cm.sup.3 in density, 10% by weight or more in boiling n-hexane insoluble matter and 100.degree. C. or higher in the maximum peak temperature T.sub.m according to the differential scanning calorimetry (DSC); and 5 to 30% by weight of an ethylene polymer (d) of 0.910 to 0.965 g/cm.sup.3 in density, wherein the total of said components (a), (b), (c) and (d) is 100% by weight.

Abstract: An ozone removing device for electrographic apparatus comprising a photosensitive screen and a corona discharge device for producing a harmful ozone is disclosed. The device comprises a casing substantially hermetically surrounding said photosensitive screen, an air circulating device for circulating an air stream through said corona discharge device in said casing and a catalyst device arranged in said air circulating device and for decomposing ozone produced from said corona discharge device, whereby said ozone is sucked into the outside of said casing by means of said air circulating device and decomposed and then flowed back into said casing again.
