Title: Apparatus establishing stable contact between an information transfer head and a flexible recording medium disc
Inventor: KANADA TOKIO
IPC: G11B17/34
Filed: 1989-08-14
Abstract: The apparatus employs a low friction pad 24 for restricting the curvature of the radially outward portion of a disc A. The low friction pad 24 is disposed at an upstream portion of a stabilizer plate 1 in the rotating direction of the disc A. In addition, the stabilizer plate is tilted upwardly towards the downstream direction in the rotating direction of the disc A. The stabilizer plate carries a magnetic head 2 and is such as to generate a Bernoulli effect drawing force for forcing the disc onto the head for establishing steady contact therebetween. The depression pad is made of low friction fabric.

Title: An automatic photographic film processing machine
Inventor: ARMITAGE DAVID HUGH
IPC: G03D17/00
Filed: 1992-03-02
Abstract: The machine is housed in an enclosure within a dark room adjacent an examination room. There is an infra-red intruder detector in each of the enclosure, the dark room and the examination room. The machine control system includes a microprocessor to which the output of each of the infra-red detectors is connected. The machine has an intermediate state of readiness between the usual standby mode and the processing mode in which it is ready to process a film on detection of a film in its infeed tray. The control system switches the machine to its standby mode only when someone is detected in a pro-determined area in the premises in which the machine is housed, otherwise the machine is switched off. The machine is switched to its normal processing mode, ready to use, when the enclosure in which it is housed, or the adjacent dark room is occupied. It would be switched to its intermediate state of readiness when someone is detected entering the examination room whilst the enclosure and the dark room are unoccupied.
Patent GB-2259508-A (GB)
Title: Valved liquid transfer systems
Inventor: ROBINSON DOMINIC JAMES
IPC: B67D7/02
Filed: 1992-03-12
Abstract: A liquid transfer system is provided to transfer liquid by gravity from an inverted small concentrate container to a larger reservoir container. The system comprises an adaptor 8 fitted into the opening of the smaller container (2 Figure 1) and a cooperating adaptor (82, Figure 4) fitted into the opening of the larger container. The adaptor 8 has a dip tube 26 sliding within a hollow body 22 and extends to the upper extremity of the inverted container. Plug valve 32 rigid with tube 26 is biased to close apertures 36 so that no liquid can drip from the inverted container. When the adaptors are coupled by displacement of the small container towards the larger container, the resultant coupling action moves plug valve 32, and liquid can then flow through apertures 36, air flowing from the large container to the inverted container (2) via tube 26 and apertures (54, Fig 3). When the two containers are moved apart the valve (46) will automatically close under action of spring 34. The large container adapter has an outer body portion (90, Figure 5) and an inner shaft, apertures in the lower end of the shaft allowing passage of air, which is drawn upwardly through shaft by vacuum created in the. small container. Liquid flowing through apertures 36 then passes through outer body portion and through openings (118, Figure 5) into the large container. The large container may have handles and a sump and be lockable in, a profiled seat (66, Figure 4). A saddle (62, Figure 6) may fit in the central opening of a closure cap of the large container, the inverted small container being seated in the saddle. The saddle may include resilient fingers (226, Figure 10). The small container may contain fertiliser or insecticide and the large container water. <IMAGE>

Title: Transistors with barrier layers
Inventor: OCHI SEIJI
IPC: H01L29/205
Filed: 1992-09-30
Abstract: A high-speed transistor includes an emitter layer 1 serving as an injection source of hot electrons and a collector barrier layer 5A disposed between a base layer 4 and a collector layer 6. The potential profile of the collector barrier layer is gradually varied from a region in the vicinity of a boundary between the base layer 4 and the collector barrier layer 5A, whereby reflection of electrons at the collector barrier layer is significantly reduced. Therefore, the current density in the ON state can be increased without damaging the high speed nature of the RHET device, and the current density in its OFF state is decreased, resulting in a high-performance and high-speed semiconductor device. An HBT (Fig 17) is also described including a multiquantum barrier between the emitter and base. <IMAGE>
