Abstract: There is disclosed a heat treatment method for a
silicon wafer. A silicon wafer, on which a natural oxide
film is formed at least at the surface thereof, is loaded
directly into a heat treatment furnace heated to a
temperature within a temperature range of 1000°C to the
melting point of silicon. Subsequently, the silicon wafer
is heat-treated at a temperature within the temperature
range, and the silicon wafer having a temperature within the
temperature range is unloaded from the heat treatment
furnace immediately after the heat treatment is completed.
The heat treatment method can be performed at low cost, and
can remove crystal defects within a short period of time,
with no use of gas endangering safety such as hydrogen.

Abstract: A rack (25,26) and pinion (28) gear mechanism, operated by the radial motion of two symmetrical spring loaded bob-weights, varies the rotational position of the cutter control shaft (40) relative to the body of the tool. The tool has one or more cutters (12) which are carried in a rigid shank (3). Radial protrusion (43) of the cutting edge (13) from the shank is governed by the position of an eccentric pin (42) fixed to the control shaft and is adjusted by varying the rotational speed of the tool. The control shaft is driven through a coupling (48). The bob-weights slide radially on guide pins (19,20). The cutters can be replaced by moving the control shaft axially on its drive pins (33,34) against a spring (39), to disengage the eccentric pin, allowing the cutter to slide out of its guide (10).

IPC: A61M27/00

Abstract: A device (10) for limiting the flow of a fluid from a first region of a patient's body
to a second region includes a primary passage (26)
for directing fluid from an inlet (18) of the
device to an outlet (20) in response to the fluid flow rate being less than a predetermined
level and a secondary passage (40) for directing fluid from the inlet to the outlet in
response to the flow rate being greater than or equal to the predetermined level. The
secondary passage can be characterized as a tortuous flow path and presents a higher
resistance to fluid flow than the primary passage. A detector (30) is operative to close the
primary passage in response to the flow rate reaching the predetermined level in order
to force the fluid to pass through the secondary passage. With this arrangement, when
the fluid flow rate reaches a level characteristic of overdrainage, the fluid is forced
through the secondary passage in order to effectively reduce the fluid flow rate and
prevent overdrainage. As soon as the flow rate decreases below the predetermined
level, the primary passage opens itself automatically.

IPC: G01N27/12
Filed: 1998-07-31
Abstract: Described are a sensing method and an oxygen sensor
for detecting a change of oxygen partial pressure in an
ambient atmosphere. The sensor (10) includes a sensing material (12)
selected from metal or its oxides which, when at an elevated
temperature and exposed to a gas containing a changing
partial pressures of oxygen, is capable of changing from one
metal or metal oxide phase to another such oxide phase and
vice versa. A typical example is the CoO/Co 3 O 4 
system. Associated with such phase change is a change
in a measurable physical property of the material. Heating
means (19), connectable to a power source, able to maintain a
temperature gradient across said sensing material are
necessary to maintain the material, during active sensing
operation, in at least two of the phases defining a boundary
line (22) therebetween which is generally perpendicular to the
longitudinal axis of the temperature gradient. The boundary
line traverses longitudinally along the axis in response to
changes in the oxygen partial pressure of the ambient
atmosphere to which the sensing material is exposed. The
sensor also includes a means (13,14;45,46) for furnishing an output signal
in response to the traversal of the boundary line across a
fixed detecting location of the sensing material
in order to detect a specific pO 2 .
