Title: Ink ribbon cassette: inking roll
Inventor: MATSUO NAOTOSHI
IPC: B41J31/00
Filed: 1991-07-31
Abstract: In an ink ribbon cassette 1, 1a, an ink ribbon 6 is moved in direction C by passing through a nip between driven roll 3 and spring-biased presser roll 4.

Title: Solenoid stator assembly for fuel injectors
Inventor: TEERMAN RICHARD FREDRIC
IPC: H01F41/02
Filed: 1991-09-13
Abstract: The stator assembly 10 comprises an E-shaped stator core 12 including three parallel pole pieces extending orthogonally 60 therefrom. Each of the outer pole pieces 20, 22 has an attachment slot formed 42, 44 in its outermost side. A coil is disposed around an insulating spool disposed on the central pole piece, and leads from the coil are connected to terminals such as 54. A flange on one end of the spool exerts outward forces on the outer polo pieces, prestressing them to resist further flexing caused by outwardly directed forces applied by fuel under pressure. An insulating cover 60 is molded around the solenoid stator assembly, the cover being bonded to the stator core by the attachment slots to enhance adherence of the cover material to the stator core and provide a barrier to any fuel attempting to traverse the interface between the insulating cover and the outer pole pieces. <IMAGE>

Title: Safe baby seat
Inventor: MACDIARMID HELEN KATHARINE
IPC: A47D13/08
Filed: 1992-07-24
Abstract: A baby seat comprises a soft but sturdy ring with a hole in the middle in which a baby can safely sit and will be prevented from toppling over in any direction. The-hole in the middle is wide enough to enable the baby to sit comfortably. The sides are high enough to support the baby's back, but not so high that he cannot see over the top, and thick enough to ensure that the seat remains securely on the floor and will not overbalance. There is an additional, optional back support (fig 2, not shown) which can fit behind the baby's back and so vary the interior dimensions of the seat in order to suit each child and to allow for growth. The ring and support may be of foam rubber. <IMAGE>

Title: Liquid dispenser: headlamp washer
Inventor: SHIBATA HIROKI
IPC: B60S1/48
Filed: 1992-12-08
Abstract: A device for washing a lamp, for example, a vehicle headlamp, includes a member for generating a pulse corresponding to a rotation of a pump-driving motor, a counter for counting the number of pulses and producing an output signal when the counted number of pulses reaches a predetermined value, and an electrical power shutting circuit for shutting off the connection between the power supply, for example a vehicle battery, and the motor when the counter produces the output signal. The pulse generator may comprise a rotatable slit plate and photo-interrupter means, as the pump motor may have a plurality of commutators when the generator comprises amplifying means. The device ensures the same amount of pumping irrespective of drive voltage, and thus conserves washing liquid.

Patent GB-2270826-A (GB)
Title: Treating turf.
Inventor: MOORE SAMUEL
IPC: A01B45/00
Filed: 1993-09-23
Abstract: A method of invigorating the growth of grass in existing grassed areas without planting any seed, comprises breaking the roots of the grass. This is achieved by a slitting action which both divides the roots and displaces the soil in the region of the roots. Disc coulters (27, 28) of a seed drill may be used to provide the slitting action, displacement of the soil being achieved by inclining the disc coulters (27, 28) sufficiently to cause soil to be displaced laterally from the disc coulters when they are pulled through the ground. <IMAGE>

Title: Detecting errors within a communication network
Inventor: SUGAWARA EIJI
IPC: H04L1/00
Filed: 1994-03-16
Abstract: In a method or apparatus for detecting the presence or absence of errors caused along a designated section of a virtual path established within a communication network, the number of errors is detected at both the entrance and exit of a detection section. The number of errors detected at the entrance is transmitted to the exit by using a path overhead of a virtual path to be monitored, and the number of errors at the entrance is subtracted from the number of errors at the exit, thereby calculating the number of errors caused along the detection section. The path overhead containing data on the detected error count includes a parity compensation bit that is set so that the parity carried in the path overhead remains unchanged. This eliminates the need to recalculate BIP-2 for the virtual path under monitoring. Various switch select methods for the path overhead interface circuits are described, Figs. 8,9, (not shown). <IMAGE>

Title: Mass spectrometer analysis of samples from electrophoresis plates.
Inventor: FRANZEN JOCHEN
IPC: G01N27/447
Filed: 1995-03-08
Abstract: A Mass spectrometry analysis of analytes, e.g. proteins, which have been separated by electrophoresis onto a gel plate is characterised by transfer of the sample from the gel plate onto a sample support plate coated with a layer of solid matrix where the transfer is by direct contact of the support plate with the moist gel plate or contact of the support plate with a moist transfer membrane. The analyte is then ionised by laser desorption and analysed by mass spectrometer. Transfer membranes may be of polyvinylidene difluoride. Typically the matrix is a cyanohydroxy cinnamic acid on a metallic support.

Title: Controlling form-fill-seal machine
Inventor: SUGA YASUTAKA
IPC: B65B9/067
Filed: 1995-08-25
Abstract: Apparatus for use in a bag forming/filling/sealing machine controls a film transportation motor (10) and an article transportation motor (18) based on the operation of a sealer driving motor (25) which is driven at a cyclic variable speed. The rotation cycles of the respective motors (10, 18, 25) are determined, based on a reference pulse which is generated by a crystal oscillator (28) and input to a central processing unit (27). When a value of the length of articles (19) to be packaged is input to the central processing unit (27), the central processing unit (27) specifies constant speeds of the film transportation motor (10) and the article transportation motor (18) and a cyclic variable speed of the sealer driving motor (25). The cyclic variable speed of the sealer driving motor is properly controlled by comparing a feedback pulse generated by an encoder (33) with a reference pulse generated by the crystal oscillator (28), while the cycle offsets of the film transportation motor (10) and the article transportation motor (18) are corrected, based on the timing signal output from an electronic cam (32).

IPC: H01L29/10
Filed: 1995-10-25
Abstract: A semiconductor device 1 comprises a plurality of layers 5, 9, 7, 11, 13 for providing rear barrier confinement potentials. An oblique (inclined) side surface 17 intersects on edges of said plurality of layers. At least one layer 29 overlies the side surface 17 so carriers can flow in a plane parallel to the oblique side surface 17. A narrowing means such as an electrode 31 has a narrowed portion 37 extending in a direction inclined with respect to the edges of the plurality of layers. The carriers are contacted by a source 25 and a drain 27 contact. The device is believed to, operate by virtue of a discrete pool of electrons (i.e. a quantum dot) formed in the region of the narrowing means 37. An array of such devices can be used as a semiconductor memory. A hemt structure is also described. <IMAGE>

Filed: 1996-02-06
Abstract: A vehicle seat (1) comprises a squab (2) and a back (3). The seat is associated with a roll-over sensor (11) which activates a pyrotechnic charge within a cylinder (12) to cause the seat (1) to move to an alternative configuration in which the head of the occupant of the seat is moved so that the clearance between the head of the occupant and the roof is increased. The head of the occupant is thus spaced further from the roof of the vehicle, since the roof of the vehicle may be depressed during a roll-over accident.
