Title: Semiconductor memory device with test circuit
Inventor: ARIMOTO KAZUTAMI
IPC: G11C29/40
Filed: 1990-03-08
Abstract: A semiconductor memory device comprises a plurality of memory array blocks (B1 to B4). In each of the plurality of memory array blocks (B1 to B4), a line mode test is performed. Results of the line mode tests performed in the memory array blocks (B1 to B4) are outputted to corresponding match lines (ML1 to ML4).

Title: Method of controlling a strainer screw press
Inventor: MUELLER SABINE
IPC: G05D17/02
Filed: 1990-09-25
Abstract: A method for controlling a strainer screw press, utilises the oscillation effect of the motor current of tamper apparatus- A control circuit generates a signal (YF) dependent upon the tamper motor current oscillations, which is used to modify a reference signal (IpSOLL), whereby the screw press motor current (IPIST) is compared with the modified reference signal (IPSOLL*) and an error signal (Y) is generated in order to drive the motor of the discharge screw. This regulates the tamper motor current and maintains an optimum pressure for maximum through-put and yield. The regulating structure is characterised by the interlinking of two single-value regulating systems which operate as a control and follower regulation system. <IMAGE>

A photographic camera having an interchangeable lens or lens part provided with a lens diaphragm, and having an adjusting means for the lens diaphragm, and a depth of focus indicating device which has two movable pointers driven by a diaphragm adjusting means is characterized in that the depth of focus indicating device is mounted on the camera and receives its drive directly from the diaphragm adjusting means which is connected to the lens diaphragm by means of a releasable coupling, the coupling connection being established by the fitting of the lens or lens part to the camera. As shown, a diaphragm blade actuating ring 30 in an axially movable lens tube 18 is controlled by an arm 34 of a ring 36, which is carried by an interchangeable lens mount 6 and is urged by a spring 40b so that arm 38 thereof is maintained in contact with an arm 42 of a diaphragm adjusting ring 44 carried by the camera between a fixed cover plate 48 and a fixed bayonet ring 2. The depth of focus indicating device is constructed according to either of Specification 793,178 or 785,857, is driven by the diaphragm adjusting ring 44, and has two pointers 56a and 58a for indicating the depth of focus limits on a distance scale 16 carried by a rotatable focusing ring 14. The interchangeable mount 6 is provided with a bayonet formation 4 for securing said mount to a bayonet ring 2 of the camera (not shown). The tube 18 is constrained to move only axially by means of engaging portions 22, 24 and has a threaded part 20 engaged by a correspondingly threaded part 10 of the rotatable focusing ring 14. In the embodiment shown, the focusing ring 14 is connected in known manner through a rotatable cam ring 25 and a sensing pin 25a to a rangefinder (not shown). In an alternative embodiment (Fig. 1, not shown) suitable for single lens reflex cameras, a second arm of the ring 36 is releasably coupled to the shutter mechanism for control thereby of the diaphragm for focusing purposes. The invention is also applicable to single lens reflex cameras which are also equipped with coupled rangefinders. The diaphragm setting ring 44 and shutter speed setting rings 44, 46 may be coupled by means not shown for exposure value adjustment.

Title: Direct current resistance welding.
Inventor: TAKANO FUMITOMO
IPC: H04R7/06
Filed: 1993-06-08
Abstract: In a method of controlling direct current resistance welding, a primary current of a welding transformer 14 is detected 18 when switching devices S1-S4 of an inverter 13 are controlled based on pulses having a predetermined frequency and each having a time width corresponding to the value of a required secondary current. Rise and fall times of the detected primary current pulses are calculated using a differentiator 24, comparators 26, 27, and counting circuits 29, 30. An upper limit frequency of the primary current is computed based on the time width of each pulse and on the rise and fall times. Thus, the primary current of the welding transformer is controlled by controlling the switching devices S1-S4 based on pulses having a frequency falling within the computed upper limit frequency, and pulse width modulated to regulate the welding current to a desired value. The transformer 14 is specifically designed to increase the frequency limit as necessary. <IMAGE>

Title: Ventable closure for pressurized containers
Inventor: RUTHERFORD STEPHEN GRAHAM
IPC: B65D79/00
Filed: 1993-04-29
Abstract: A closure arrangement comprises a cap 1 with means for sealing the cap onto a container and an opening 9 in the wall of the cap normally sealed by a member 5 located within the cap and biased to seal the opening when the cap is fitted to a pressurized container, vent means eg. apertures 11 being associated with the member 5 to release pressure only when the member 5 is moved eg. by pressing boss 10 against the bias to unseal said opening 9. The member 5 is preferably pre-biased into the sealed condition and may comprise an oversized diaphragm of resilient material with its perimeter gripped by internal ribs 6. The opening may be shaped as a nearly circular slit (9A, Fig. 4) to provide hinged area (15, Fig. 5) which is depressed to release the pressure. Slit (9A, Fig. 4) may be formed from a line of weakness using a tear off tab (not shown). The arrangement is suitable for bottles containing carbonated drinks. The cap may be fitted by a screw thread to the container. A hinged cover (13, Fig. 1) may be provided to protect opening 9, or the opening 9 may be recessed (Fig. 7). The closure arrangement prevents the cap flying off the container by enabling pressure to be released before opening. <IMAGE>

Title: Rotation transmission device
Inventor: ITOH KENICHIRO
IPC: B60W30/18
Filed: 1994-06-08
Abstract: A device mounted on a four-wheel drive vehicle and capable of driving the rear wheels while the vehicle is being accelerated, and disconnecting the driving force to the rear wheels while being braked comprises an inner member (2) coupled to the rear wheel propeller shaft and an outer ring (1) coupled to the rear wheels. On opposed surfaces of the inner member and the outer ring are formed a cylindrical surface (6) and a plurality of cam surfaces (7), between which are defined wedge-shaped spaces. A retainer (8) is provided between the inner member (2) and the outer ring (1) and is formed with pockets to receive rollers (12). A turning effort imparting means (22) is coupled to the retainer through a one-way clutch (18). A torsion coil spring (17) for producing turning effort is mounted between the retainer (8) and the inner member (2). When the one-way clutch (18) is switched on or off, the direction of turning effort applied to the retainer (8) changes. The rollers (12) are thus kept in one of the two opposite engageable positions when the inner member (2) is rotating in either direction. The rollers may be replaced by sprags. <IMAGE>

IPC: F16H59/70
Filed: 1995-06-05
Abstract: Gear shifts which are initiated by the driver via the selector device 7 and which would result in inadmissible engine speeds are prevented and it becomes possible to permit them again only via stored shift-line characteristic diagrams 14. The arrangement processes input signals 10 to 13 relating to the position of a the selector device 7, the transmission output speed, engine load and the transmission ratio currently engaged, and operates to form a reference signal related to the position of the manual selection member or the transmission ratio currently engaged. The arrangement then checks whether the reference signal corresponds to a ratio which is lower than the current ratio, a computing stage checking whether a shift to a requested ratio would result in an engine overspeed condition. <IMAGE>
