Inventor: KOZUKA YOSHINARI
IPC: G01R33/032
Filed: 1989-07-10
Abstract: A method and an apparatus for measuring the strength of an AC electric field or an equivalent voltage, or the strength of an AC magnetic field or an equivalent current, based on a light beam which is transmitted through and thus modulated by an optical sensing head (2) due to the Pockel's and Faraday effects, while the sensing head is exposed to the AC electric and magnetic fields. The sensing head includes an optical material (36) which exhibits the Pockel's effect and an optical material (38) which exhibits the Faraday effect, or includes an optical material (4) which exhibits both the Pockel's and Faraday effects. The modulated beam is applied to a light-sensitive element (28), which produces an electric output signal. A first and a second component of the electric output signal are retrieved by respective detectors (30, 32). The first component has a same frequency as that of the electric or magnetic field, while said second component has a frequency which is two times that of said electric or magnetic field. The electric field strength or the voltage, and the magnetic field strength or the current are determined by one and the other of the first and second components, respectively.

Abstract: In the method described, the monitoring is carried out by means of symmetrical bipolar current pulses. The cycle time of the current pulses can be freely chosen and can be variably adjusted in accordance with the test accuracy required. This makes it possible to carry out the monitoring in steps, the individual steps differing in the chosen cycle time of the current pulses injected and, consequently, in the test accuracy to be achieved. The symmetrical bipolar current pulses are produced in a simple way by means of a voltage divider circuit, without large expenditure on equipment. The cycle time is expediently set by means of a program-controlled apparatus which is also used to store, process and transmit the resultant measured values. The method is advantageously used in processing chemistry, in microbiological methods and in foodstuffs technology. It enables any errors which occur, such as damage to the ion-sensitive membrane, shortcircuits or cable open circuits, to be detected and information on the qualitative state of the electrodes to be obtained quickly and without considerable expense, with minimum disturbance of the process cycle. <IMAGE>

Abstract: A papermakers' fabric, especially a forming fabric, with very high fiber support and open area on its top surface for superior papermaking characteristics. The papermaking surface consists of a woven fabric layer (10) with single float machine direction yarn (14) knuckles; i.e., no machine direction yarn (14) passes over two or more adjacent top surface cross machine direction yarns (12). To complete the papermaking surface, into this base structure is woven two additional, generally smaller diameter, cross machine direction yarns (15, 17) for every cross machine direction yarn (12) in the base weave papermaking surface. These two additional cross machine direction yarn pairs (15, 17) are woven in reverse weave patterns to one another such that natural interposing forces cause the two yarns (15, 17) to align one over the other centrally between two adjacent cross machine direction yarns (12) of the fabric layer (10). One yarn (15) of the interposing pair (15, 17) functions as an additional fiber supporting yarn (15) while the other yarn (17) acts as a locator yarn (17) to position the fiber supporting yarn (15) in the proper or ideal location on the papermaking surface.

Abstract: A photosensitive negative-working solder-resist (5) and a photosensitive layer of a photographic material with a silver halide base or a negative-working photoresist are applied in succession over the entire surface of the printed circuit board. Selective exposure in the region of the plated-through holes (3) and/or solder pads (4) forms a mask (600) at these points which screens the plated-through holes (3) and/or solder pads (4) during the subsequent exposure of the solder-resist (5). After the solder-resist (5) has been selectively exposed, preferably with floodlight (F), only the mask (600) and the unexposed regions of the solder-stop resist (5) situated underneath have to be removed. The method according to the invention is suitable, in particular, for applying a solder-stop coating to three-dimensional printed circuit boards since in this case conventional masking techniques cannot be used for structuring the solder-resist. <IMAGE>

Abstract: The preparation of highly densified ceramic bodies by the sintering of certain organosilicon polymers, carbon sources, silicon carbide powders, metal-containing sintering aids and, optionally, curing agents is described. Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process. The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities. One advantage of the present invention is that the green bodies have relative high strengths and thus can be easily handled and, if desired, machined before sintered. A second advantage is that any organosilicon polymer can be utilized, regardless of char yield or free carbon value, since the carbon is derived from a carbon source which yields a carbon char upon pyrolysis.

Abstract: A computer based customer order promising and confirming method system automatically interfaces to a production planning system to provide an integrated approach to the front-end planning process. The process estimates pro­jected order completion based on customer requested or­ders. First, the customer requested orders are received and the requirements (as specified by the orders) are entered in the planning system. Next, a check is made to see if the requirement(s) can be satisfied by either unallocated inventory or unallocated scheduled production. If the results of this check meet the requirement(s), the information is provided for order- promising pending order confirmation. If the results on the other hand do not meet the requirement(s), the process then utilizes the logic of a material requirements planning system (MRP) to explode the requirements and generate a statement of time phased dependent requirements. The logic of the MRP is used to simulate the process of procurement and/or fabri­cation of the necessary components to calculate possible delivery dates. The effect of releasing new or­ders/requirements is further simulated by capaci­ty/resource planning logic to verify if production capaci­ty is available to meet delivery dates requested by the customer or suggested by MRP. Following the simulation process, the system provides the order processing operator with clear information on best available date(s) if re­quested, whether the customer specified date(s) can be met, and if customer specified date(s) cannot be met, the best available date(s).
