Abstract: There is provided a developing unit having the function to decide freshness/oldness of a developer by using a toner sensor. Toner concentration of the developer is detected by the toner sensor and when an output voltage of the toner sensor is higher than a reference voltage by a constant value or more, the developer is determined to be fresh and based on this result, a main motor is driven to rotate rollers in a developing tank, thus stirring the developer. On the other hand, when the developer is determined not to be fresh, not only the main motor but also a toner motor is rotated for toner replenishment so as to adjust the toner concentration.

Abstract: It has been noticed that the patterns produced by photoetching are subject to pattern broadening where the results are not as sharp as expected. It has now been realised that this is partially caused by the diffussion of the active species away from the region where they were created. To reduce this pattern broadening, the substrate is protected by a fugitive coating which is removed by the illumination. Native oxide coatings are particularly suitable for InGaAsP substrates. These are conveniently applied by exposing to substrate to 20⁰/o O₂ + 80⁰/oN₂ for about 3 minutes at 450⁰C.

Abstract: An image output device for performing resolution enhancement for characters, and maintaining original image quality for images which have been subjected to a gradation processing. In the image output device, when input data is character data, the bit image data of character data is stored in a first development memory, while when input data is image data, the bit image data of image data is stored in a second development memory. Upon read-out of data for one page, the bit image data in the first development memory is transferred to a resolution-enhancement processing circuit to be subjected to a resolution enhancement processing, and is then synthesized with the bit image data in the second development memory.

Abstract: A wrist-watch (11) which is completely troublefree for the user is produced by combining a radio clock (26, 27) with, for example, a long wave antenna (35) which is integrated into the bracelet (strap) (36) and serves to receive the absolute time information sent in code form, in combination with an electrophysical or electrochemical memory (store) (16) which is recharged from at least one solar cell (38). Since this wrist-watch (11) runs eternally and with regard to its pointer position is compared cyclically, for possible automatic display corrections, with the absolute time information received via radio, this wrist-watch (11) can be fitted per se with a hermetically encapsulated, completely closed housing (12). However, in order to be able to subject the element most susceptible to malfunction, specifically the memory (16), to a performance check, the housing (12) is provided after all with a through opening, for example in the form of a hermetically resealable threaded bore (54) through which at least one contact point (59) can be accessed by a test prod (probe) in the course of the guidance of the electrical conductor to the memory (16), in order to be able to observe how the stored charge rises as a function of strongly heightened radiation of the solar cell (38). Again, direct rapid electrical charging of the memory can be performed via this access from a charger which is adjusted with regard to the voltage limitation. Finally, overpressure can be pumped into the housing interior (17) through the opening released, in order that the watch glass (50) pressed radially into the housing wall (21) can be pressed out axially and then the sandwich structure in the housing interior can be dismounted for the purpose of servicing. <IMAGE>

Abstract: A device and method for activating the circulation of the lymphatic system in the legs of a user (100), is described. The device includes a T-shaped support 12 having a main shaft 14 with a cross shaft 16 mounted at the proximal end 14B and a base 18 mounted at the distal end 14A. Coil springs (26, 28) are mounted at one end to ends (26A, 28A) of the cross shaft or arm and at the other end (26B and 28B) to the supporting stirrups (30, 31) for the heel 103A of the user in a sitting position. The base is comprised of a first crossbar 18A and a second crossbar 18B which can be disassembled for shipping and storage. To activate the circulation of the lymphatic system, the heels of the user are first inserted into the supporting stirrups. Next, the user applies a downward force on the stirrups with the heels and finally, the user releases the downward force on the stirrups. The springs are constructed so that the legs of the user are moved in a vertically oscillating direction without significant exercise of the leg muscles and is particularly adapted for users who are unable to participate in normal activity due to age, illness or accident.

Abstract: A plurality of special multi-element registers (115, F20-F30), called "vector registers" herein, are incorporated into a scalar computer. The vector registers are controlled to sequence the transfer of vector data between a main memory (101) and a processing unit (100) of the computer to occur one element at a time until an entire array of vector data has been processed. The vector registers operate concurrently with the processing unit and the main memory. A common address scheme is used between the vector registers and the scalar registers (f0 - f31) of the computer so the vector registers are visible in the scalar register address space. Pointers (302) are used in the vector registers to keep track of the order of the array elements during processing. Vector registers are used to store intermediate results of the vector processing operations.

Abstract: An ink jet apparatus offers enhanced print quality and is highly conducive to mass-production. The apparatus has a piezoelectric ceramic arrangement including a plurality of ink channels filled with ink. The ink channels are defined by walls and correspond to nozzles. The walls are deformed selectively by a piezoelectric effect to vary the volumes of the selected ink channels to jet out the ink through the corresponding nozzles. The center position of each of the nozzles is allowed to deviate from the middle between one wall of the corresponding ink channel and the other wall opposite thereto by half the distance between the two walls minus half the diameter of the nozzle within the half distance. This arrangement reduces the number of defective ink jet printer heads in the manufacturing phase and allows the ink jet apparatus to offer enhanced print quality. Such an apparatus is also highly conducive to mass-production with no need for specialized adjustments of individual nozzles.

Abstract: A display arrangement comprises an image intensifier tube 1 or some other device which provides a representation of a viewed scene at 3. A supertwist LCD 4 and associated polarisers 5 and 6 are located between the output 3 and a viewer 7. A ferroelectric liquid crystal shutter 11 is located between the LCD 4 and second polariser 6. The LCD 4 is controlled to produce symbology. By switching the shutter 11 the polarisation of the incident radiation is switched between two states differing by 90°. This causes the LCD 4 to operate in two states. In one state the viewed scene is transmitted through the LCD 4 and in the other state it is absorbed and any symbology on the LCD 4 is contrasted with a dark absorbing background. The shutter 11 is switched sufficiently quickly that the observer 7 perceives the symbology overlaid on the viewed scene.
