Title: Chair
Inventor: LANUZZI MAX
IPC: A47C3/026
Filed: 1987-05-25
Granted: 1991-01-15
Abstract: Abstract of the Disclosure A chair with a seat support (7) has a seat plate (ll) which is supported to the seat support (7) by means of a rear and a front guide rod.  The chair has a back rest support (14a) that is pivot-hinged to the seat support (7).  The seat support (7) is connected to a rigid, back rest angle support (7) by means of a front and a back parallelogram guide rod (3).  The angle support is fixed to the bottom part of the chair (2).  The parallelogram guide joints (3) are also connected to each other by means of a parallel guide rod (4).  A first force storage member (5) is situated between the seat support (7) and the back rest angle support (1) and a second force storage member (15) is located between the back rest support (14a) and the seat support (7).          The force necessary for the slope of the back rest is independent of the weight of the user.  A user with higher weight must expend a higher amount of force for the slope of the back rest to move backward than a user with a lower weight.

Title: Frequency synthesizer
Inventor: SAITO SHIGEKI
IPC: H03L7/197
Filed: 1987-12-22
Granted: 1991-10-08
Abstract: ABSTRACT    This invention aims at offsetting a phase difference caused by a delay in a frequency synthesizer which is intermittently actuated for power reduction by setting the division ratio at two levels at the time of releasing reset signals at the variable frequency divider so that the delay time is adjusted by the fre-quency division in the first cycle.  The synthesizer sets the ordinary division ratio in the second cycle and thereafter, and if there is still a phase difference, it sends reset signals again to the variable frequency divider repeating the aforemen-tioned operations.  This frequency synthesizer can realize an ideal intermittent operation without significant frequency fluc-tuation by repeating the above operations to reduce the phase difference at the variable frequency divider to one cycle of the input signals of the counter or less (e.g. about 1.3 nsec in 800 MHz).

Abstract: Abstract A system for optimal space utilization by using at least one raisable and lowerable berth.  The at least one berth can be raised to a storage or day position and lowered to a service or night position by  a  driving  motor  operatively  connected  to  the berth.    The position of the berth is essentially horizontal  in  the  storage  as  well as  the service position.   The berth is provided with guiding bodies for  movable  engagement  along  essentially vertical guide rails fastened adjacent to limiting walls of the compartment in question.    The guide rails can also be  a part  of  the  bearing  structure  of  the compartment.   Below the berth there are arranged at least  one  permanently  mounted,   pivotable  chair capable of being stowed and/or put down in a position to free the necessary space for lowering the berth to the night position.

Title: Ink-jet printhead-to-paper referencing system
Inventor: RASMUSSEN STEVE O
IPC: B41J13/28
Filed: 1988-08-05
Granted: 1992-09-01
Abstract: INK-JET PRINTHEAD-TO-PAPER REFERENCING SYSTEM                 ABSTRACT OF THE DISCLOSURE    Several problems of alignment associated with ink-jet  printers are alleviated by four aspects.   In  the first,  a reverse bow ( ) in the paper (12) is created for  printing on single sheets of paper.   The  reverse bow,  which  is in the transverse axis  of  the  paper, forces the paper flat against the platen (12) by  using the paper's own stiffness.     In  the second aspect, the paper and the  carriage (30)  are  referenced to the same  part  (the  carriage guide (10)).  In this configuration, the paper is urged against  the underside of the carriage  guide  off  of drive  rollers (18), through the reverse bow, and  onto the platen, where it is printed.  The carriage is  ref-erenced to the carriage guide through a slider bump  by means of a carriage shaft and gravity.     The  carriage  guide comprises  stiff  thin  sheet metal,  which is closely-toleranced and  has  well-con-trolled dimensions.  Thus, this part is good to  refer-ence  to,  rather than molded-in parts, which  are  not stiff  enough at the required thickness.   Straightness is also difficult to achieve at the required  thickness with plastic parts.     In the third aspect, the platen is allowed to move substantially  perpendicular to the plane of the  paper to accommodate thicker print media.     In  the fourth aspect, the platen is maintained  a minimum fixed distance from the carriage guide by bumps  (38)  to ensure that the  paper  is  not pinched between the carriage guide and the platen.

Abstract: This invention describes a series of Fe-Mn-Al-C based corrosion resistance alloys.  It also describes how to obtain such alloys which has comparable good corrosion resistance in many environments to conventional stainless steel as 304 and 430.  The correlation of chemical compositions among the manganese, aluminum, carbon and other minor elements are discussed.  Therefore they are made to be practical and more definitive.  According to more advanced understanding in overall of the Fe-Mn-Al-C based alloys that are included in this invention have to be surface treated and/or pickled, passivated by the methods included in this invention.  After the surface treatments, the final products will have an obviously comparable depleted manganese and/or higher chromium on the alloy surface and will have better corrosion resistance than the conventional Fe-Mn-Al-C and Fe-Mn-Al-C-Cr based alloys.  In addition, the manufacture and fabrication processes for the present designed Fe-Mn-Al-C based alloys also include the meltings, mixings, ingot castings, hot workings, cold workings, heat treatments and surface treatments.

Abstract: Abstract:          A preform tube is caused to be collapsed into a preform rod by causing a heat zone provided by a torch assembly to traverse the tube longitudinally in a plurality of passes.  During this so-called collapse mode, a muffle tube encloses that portion of the tube which extends through the torch assembly.  Advantageously, the muffle tube projects a predetermined distance beyond one major face of the torch assembly.  The torch assembly comprises annular semi-circular end plates and an annular semi-circular center portion having a plurality of exit ports through which gases are directed into engagement with the tube.  The center portion is caused to be recessed between the end plates thereby causing the heat zone generated by the gases to be narrowed.  The narrowing of the heat zone and the substantial confinement of the heat energy within the muffle tube cooperate with increased gas flow rates to cause the tube to be collapsed in a time period which is substantially less than that achieved by prior art methods.

Title: Telephone handset construction
Inventor: BROWN REED S

Filed: 1989-09-13
Granted: 1992-10-13
Abstract: Abstract of the Disclosure A telephone handset comprises elongated complementary upper and lower housing members that mate at their perimeters to form a hollow handset housing. The lower housing member includes a pair of spaced-apart transducer receiving cavities, each being shaped to receive a cylindrical transducer surrounded by a flexible tubular gasket and form an acoustic seal therewith. Each gasket includes flanges around its circumference that project radially outward and in a direction opposite to the direction of insertion of the transducer/gasket assembly into its associated cavity. Such construction provides adequate mechanical retention between the transducer and the lower housing member and avoids the need for additional retaining hardware. The upper housing is joined to the lower housing using one or more pairs of side-mounted, interlocking hooks and latches. The upper housing further includes ribs, molded therein and positioned to maintain the transducers in place when it is joined with the lower housing.
