Title: Moulded shower enclosure
Inventor: BAKER STEPHEN
IPC: A47K3/28
Filed: 1993-08-16
Abstract: The invention relates to a moulded shower enclosure formed in three parts one above the other, and including a base part (13), a central U-shaped part (14) and a top part (15). The enclosure has a base (25), defining a waste outlet (30), and a back (18) and two side walls (16, 17) and has no vertical joints or seams. Support feet (26) project downwardly from the base for supporting the enclosure on the ground so that waste pipes (31) can be located between the base and the ground (27). The parts (13, 14, 15) are formed at their mating surfaces by connectable and disconnectable fixing means (47, 48), so that the enclosure has its own structural stability. <IMAGE>

Title: Display tank for sea-water fish
Inventor: YOSHIDA NORIHIRO
IPC: A01K63/00
Filed: 1994-12-28
Abstract: Sea-water fish are raised in a display tank which includes a device 4D for circulating the water in the tank, and a filtering material supporting plate 1 having a sand-like filtering material 3 containing calcium thereon. In this case, the grain size of the sand-like filtering material is set between 2.5 - 3.5 mm. Coral sand is preferably used as the sand-like material, since it promotes the propagation of aerobic bacteria and converts ammonia and nitric acid to harmless materials and the above grain size exhibits better effect. An external filtering system C may be disposed outside the tank, with a feed-out tube for feeding the water in the tank to the external filtering system, and a mechanism for circulating the water which has been filtered by the bottom filtering section through the feed-out tube and the external filtering system into the tank again. The feed-out tube can be provided with a bypass mechanism for feeding the water in the tank to the external filtering system directly without passing the bottom filtering section. <IMAGE>

Title: Programmable controller and methods of setting and displaying its internal information
Inventor: ITAMI SHINZI
IPC: G05B19/05
Filed: 1994-03-17
Abstract: A programmable controller has a programmable controller unit 3104 and a peripheral device 101 which facilitates defining and managing set values of both the internal devices of the programmable controller and the upper and lower limit values by allowing the programmable controller unit and the peripheral device 101 to store set values as reference values for judging the magnitudes of current values of information and updating these values under the control of a sequence program. Further, the programmable controller and peripheral device facilitate the consecutive display, real-time display, etc. of the contents of internal devices (e.g. counters, timers,) by displaying sequentially the contents of these internal devices at predetermined intervals under the control of a sequence program. Additionally this invention allows numerically represented character information stored in internal devices of a programmable controller to be displayed in the form of characters by a simple peripheral device. This display operates under the control of a sequence program and converts stored internal information into character information which indicates display shapes. <IMAGE>

Title: Papermaker's fabric
Inventor: HODSON MARK
IPC: D21F1/00
Filed: 1995-08-24
Abstract: A papermakers fabric (10) is woven from machine direction yarns (11, 19, 20) and one or more layers of cross machine direction yarns (12 - 18) which in at least one of the layers comprise relatively large (12, 13, 16, 17) and small (14, 15, 18) yarns.

Title: Soft-start arrangement for high-power module with large capacitor storage bank
Inventor: LUBOMIRSKY VADIM
IPC: H02H7/16
Filed: 1996-05-15
Abstract: A high-power DC module, eg. for supplying an RF amplifier 35, trickle charges a capacitor bank 34 prior to closure of a power switch 33 to avoid large inrush currents at power up. Trickle charging may be effected via a PTC thermistor 36 connected in shunt across the switch 33. Alternatively, the thermistor 36 may be replaced by a metallized film capacitor acting as a voltage dropping and current limiting element, this capacitor having a much smaller capacitance than the bank 34. The capacitor bank may be charged from a three-phase AC source via a rectifier (45, Fig.5; 145, Fig.6) connected to the AC source through a three-pole contactor (43; 143) with a respective PTC thermistor (46A, 46B, 46C) or metallized film capacitor (146A, 146B, 146C) connected across each pole of the contactor.

The capacitors are connected to an integrated circuit (23) which detects changes in capacitance caused by small forces applied to the button (10) to provide signals representative of contact with the button (10) and/or the force applied by the button (10) and the plunger (P). The drive head (1) also carries spring loaded pawls (26, 27) which engage behind the flange of the plunger (P) of the syringe (S) to prevent plunger movement caused by siphoning or other undesired movement of the plunger.

Title: Restoration of pulse width in buffers with unequal leading and trailing edge propagation delays
Inventor: SON JIN SEUNG
IPC: G11C11/4093
Filed: 1997-06-03
Abstract: The PMOS and NMOS transistors in the cascaded inverters IV11-IV15 are dimensioned so that the delay of the leading edge of an input pulse is minimised at the expense of increased trailing edge delay. To reduce trailing edge delay, the trailing edge of the input pulse is detected by circuit 31, which outputs a short pulse on node N7. This pulse propagates through the inverter string IV16-IV19 and actuates the speed-up transistors MP1-MP3 and MN1-MN2 to assist charging or discharging respectively of nodes in the main inverter string IV11-IV15. Alternatively, the short pulse may be delayed and applied to a logic gate at the end of the inverter string to end the output pulse (figure 5). The circuit may be used in memory input buffers.
