Title: Semiconductor memory device
IPC: G11C11/404
Filed: 1990-03-29
Abstract: A semiconductor memory device includes a plurality of memory cells each having a bipolar transistor (Q2) 
whose collector-emitter voltage V CE  is controlled according to the base potential to satisfy the condition of 
I BE  < I CB  when the forward base current in the base-emitter path and the reverse base current in the 
collector-base path are respectively expressed by I BE  and I CB  and a switching element (Q1) connected to the 
bipolar transistor, word lines (WLn), bit lines (BLn) and emitter electrode lines (VEn) connected to the memory cells, and 
functions as a dynamic memory cell in the data storing operation and as a gain memory cell in the readout operation.
Patent EP-0397359-A3 (EP)
IPC: F01L9/20
Filed: 1990-04-27
Abstract: A cycle changeable engine includes first 
intake valves (1) for a four-cycle operation which are 
disposed in intake ports (11) formed in a cylinder head (3), 
exhaust valves (2) disposed in exhaust ports (22), second 
intake valves (5) for a two-cycle operation, disposed 
in intake ports (9) formed at the lower part of a cylinder (6), 
and an electromagnetic valve driving device (10) for 
opening and closing each of the valves by electro­
magnetic force. The engine includes also a controller (15) 
which actuates either the first or second intake 
valves for opening and closing with the others being 
kept closed in response to a detection signal from 
detection means for detecting the number of revolutions 
or load of the engine, and changes the operational 
condition of the engine to the two-cycle or four-cycle 
operation. In this manner the engine is operated 
in the two-cycle operation at a low speed revolution 
of the engine to improve an output torque and is 
operated in the four-cycle operation at a high speed 
revolution of the engine to reduce fuel consumption, 
to improve mean effective pressure and volume 
efficiency and to reduce noise.

IPC: A01C17/00
Filed: 1989-06-07

Title: Liquid crystal apparatus
Inventor: IWAMOTO HIROFUMI
IPC: G02F1/13
Filed: 1990-12-28
Abstract: A liquid crystal display apparatus is constituted by using (a) a liquid crystal panel comprising a pair of substrates each provided with an electrode and a liquid crystal disposed between the substrates in combination with (b) a supporting member having a frame for supporting the liquid crystal panel. The liquid crystal panel is fixed in a floating state to the frame of the supporting member by the medium of (c) an elastic member so as to define an almost closed space defined by the liquid crystal panel, the supporting member and the elastic member. The almost closed space functions to suppress a deleterious flexural deformation of the liquid crystal panel in response to external mechanical forces, such as dropping impact and vibration, and also provides a good heat efficiency when it is used in combination with a planar heater for heating the liquid crystal panel. <IMAGE>

Patent EP-0681402-A3 (EP)
Inventor: KIM WILLIAM E
IPC: H04N7/081
Filed: 1995-05-02
Abstract: A system and method for modulating a data signal uses a phase shifting
transformer function to phase shift the lower and upper sidebands of the data signal so
that the sidebands of the data signal have a 180° phase shift with respect to each other
( i . e ., are complementary). The phase shifted sidebands are added to a standard video
signal and then transmitted. A television or other video receiver demodulates the
video signal with a simple demodulator circuit, which causes the upper and lower
sidebands to be summed together. The data signal, with complementary sidebands,
cancels out so that the data signal does not interfere with normal video operation. The
upper and lower sidebands of the data signal are processed separately from the video
processing circuitry of the television receiver. An inverse phase shifting circuit
performs a second phase shift operation on the upper and lower sidebands of the data
signal so that the data signal can be demodulated and the data signal recovered.

cylindrical drum mounted within a cabinet and having a
plurality of compartments of varying size which pass by
at least one access door. The access door is mounted in
the cabinet for sliding movement to allow access to a

Abstract: A sanitary napkin with laterally projecting
positioning tabs. The adhesive securement system of the
sanitary napkin includes three adhesive zones in a spaced
apart relationship, namely one zone on the main body of the
sanitary napkin and one zone on the undergarment facing
surface of each positioning tab. A quick-remove peelable
protective layer covers the adhesive zones when the
sanitary napkin is not in use. The protective layer
includes a primary release strip extending longitudinally
on the sanitary napkin to cover the adhesive zone on the
main body and a transversal secondary release strip
overlaying the adhesive zones on the positioning tabs.
This arrangement allows to remove the entire protective
layer in a single peel-off stroke. The invention also
relates to a method and apparatus for folding a positioning
tab of the sanitary napkin over its main body during a
packaging operation that inserts the sanitary napkin in a
disposable pouch. The method comprises the steps of
creating a crease in the transverse release strip of the
protective layer, near the juncture between the positioning
tab and the main body of the sanitary napkin. The
transverse release strip is made of sufficiently rigid
paper material so the crease maintains the positioning tab
in a folded condition during the packaging operation.

Abstract: The invention describes a method and apparatus for encrypting
predetermined information using a predetermined encryption key and which
uses the steps of hierarchizing the encryption key by means of a one-way
function and decoding the predetermined information using the
hierarchized encryption key. An encryption key of the next hierarchy
(Ver.n) is formed relative to an encryption key of the first hierarchy
(master key) Ko by using a one-way function F. The one-way function
performs an irreversible calculation in which the key K1 can easily be
determined from Ko but the reverse calculation cannot be performed
substantially. Further encryption keys K2, K3, ..., Kn-1 are
sequentially calculated using F resulting in a set of hierarchized
encryption keys. The invention is particularly applicable to the
recording and decoding of software or other data on recording media such
as digital video disks, or to the supply of such information over a
transmission network.

Abstract: A watertight body (10) having a first (1a) and a second (1b) body shell
of rigid polymer material that can be joined together for accommodating a
photographic camera (11) is designed such that, using a multiple-component
injection moulding process, a sealing means (2) comprising elastic
polymer material is moulded on an edge (2a) of at least one body shell
(1a, 1b) that forms the joint, and a covering means (3) is moulded on
surface areas of said body shells and is connected to the body shell by
chain looping of the polymer materials. The result is that the body is reliably
sealed against water and is nevertheless inexpensive and simple to
manufacture. For a simple and correspondingly inexpensive recyclability of
the body, the body shells (1a, 1b) can be crushed without separation of
the polymer materials using known devices, with the resultant material
mix being usable as an admixture for the manufacture of new camera components.
