Inventor: QIU HONG
IPC: C04B35/493
Filed: 1998-03-24
Abstract: A piezoelectric device for an ink jet print head that
has a greater displacement at a low drive voltage. The
ink-jet recording head comprises vibration plate, on which
is mounted one or more piezoelectric devices that change
the volumes of pressure chambers upon application of a
voltage. The device is mounted at least on one face of
a pressure chamber substrate that is to be filled with ink.
Such piezoelectric device (4) a second piezoelectric
layer (42) having a piezoelectric constant g of a constant
value or higher; and a first piezoelectric layer (41)
having a dielectric constant of a specific value or higher.
Since the piezoelectric constant d of the piezoelectric
device correlates with the product of the largest
piezoelectric constant g and the largest dielectric device
of the piezoelectric devices, a piezoelectric constant d
larger than in the conventional case, i.e., having a
greater displacement, can be obtained.

Filed: 1998-01-19
Abstract: Footwear intended primarily for outdoor use, wherein a variety of ground
conditions are likely to be encountered, has a sole with traction elements inspired by the
hoof of a mountain goat. In several embodiments, an interior region of the sole is
provided with a plurality of pairs of relatively soft protruding pods, while a perimetric
region surrounding the interior region includes a plurality of relatively hard lugs provided
on opposite sides of the pod pairs. The pods extend downwardly below the lugs such that
they will make initial ground contact and compress. The compression cushions initial
impact and increases the area of ground contact to improve traction on firm smooth
surfaces. The compression also brings the lugs into ground engagement, following initial
contact, to improve stability and traction on irregular and soft ground surfaces. Other
embodiments of the invention implement similar principles, in soles having a more
conventional (less goat hoof-like) appearance. In one embodiment, relatively soft rubber
outsole lugs take the place of the pods. In another embodiment, the sole includes
combination lugs including relatively hard and soft portions of differing height. In a
further embodiment, an interior region of a water sandal sole includes relatively soft
traction elements in the form of relatively large soft regions of the midsole covered with
a thin layer of rubber outsole material; the interior region is surrounded by a perimeter
of hard lugs.

sealing against the obturator assembly or surgical instruments passed through the
cannula assembly. The seal assembly includes an upper seal arrangement having
an aperature. The seal assembly also includes a pressure seal located beneath the
upper seal arrangement. The pressure seal includes a pair of side walls. At least

Abstract: In a common buffering device with a simple arrangement,
a write address can be efficiently released from a buffer
memory upon receipt of a multi-address call. For an ATM
cell which is to be transmitted to a specific line, a write
address is set in a common buffer memory, and the ATM cell
is written at the write address. The ATM cell is read from
an address which corresponds to the write address, and is
transmitted to the specific line. Then, the pertinent
write address is released. In a write table are entered
a plurality of multi-address lines across which an ATM cell
written at a specific address in the common buffering device
can be multicast. Each time the ATM cell is read from the
specific address, a designation line for transmission of
an ATM cell in a read control table is compared with the
multi-address lines set in the write control table. When
the lines match, the write address for the ATM cell, which
is set in the write control table, is released.
