Abstract: A process and apparatus for the low-temperature separation of air with variable oxygen production are described. Compressed, pre-purified and cool air (line 5) is pre-separated in the pressure stage 10 of a two-stage rectification 9. The bottom liquid thus formed is further separated in the low-pressure stage 11. Liquid nitrogen 14 from the pressure stage 10 and liquid oxygen from the low-pressure stage 11 can be temporarily stored in tanks 35, 32. In addition, a liquid-air tank 14 is provided for storing bottom liquid 12 from the pressure stage 10. If the production of oxygen is increased, the throughput in the pressure stage 10 can be increased and at the same time the throughput in the low-pressure stage 11 and the reflux ratios in the two rectification stages 10, 11 can be kept constant.

Abstract: A process and apparatus having improved efficiency for forming a semi-solid alloy slurry. A molten metal in a containing device is mixed electromagnetically by a moving, non-zero magnetic field provided over substantially all of a solidification zone within the containing device. The magnetic field causes the shearing of dendrites formed in the solidification zone at a desired shearing rate. The magnetic field is generated by a device supplied with current at a desired line frequency. By operating within a defined range of line frequencies, a desired shear rate for attaining a desired cast structure at reduced levels of power consumption and current can be achieved.

Abstract: A hybrid reheating of polyester preforms which are to be stretch blown into containers wherein the reheating coupled with the controlled quick initiation of the blow stretch operation after final reheating produces a container which may be filled with a hot fill without there being any disadvantageous shrinkage of the container. The reheating is by way of a specific combination of quartz oven reheating and radio frequency reheating together with specific equilibrations of the temperature cross sectionally of the preform body. Polyester preforms may be reheated to a cross sectional center temperature ranging from 225 DEG F to 260 DEG F and stretch blow molded without undesirable surface crystallization occuring while the ability of the container to be filled with a hot fill substantially without shrinkage is increased.

The chain links comprise a unitary body (12) having guide rollers (16,18) for guiding the chain through a track which may have a significant curvature due to the unique pivot ball (20) imbedded within the body of each link. The pivot ball serves as a swivel for the roller shaft and performs the dual functions of joining two adjacent links and supporting a pair of vertical guide rollers (16,18). Each link is provided with an arrangement for positively and securely mounting a gripper assembly thereof.

Abstract: PROBLEM TO BE SOLVED: To reduce a memory capacity for storage of a sound waveform database to increase the retrieval speed for voice synthesis. SOLUTION: A voice data volume reduction processing part 45 calculates a prescribed degree of similarity related to metrical feature parameters and acoustic feature parameters for each pair of phonemes (biphone) on the basis of a list of biphones; and if the calculated degree of similarity is equal to or higher than a first prescribed threshold and the number of same biphones in the list of biphones is equal to or larger than a second prescribed threshold, data of sound segments of a sound waveform signal related to one of these biphones is deleted from the sound waveform database to reduce the voice data volume. A text database and the voice waveform database where the voice data volume is reduced are used to perform voice synthesis processing.

IPC: G11B20/14
Filed: 1985-12-20
Abstract: A method for rapidly recovering the clock from Manchester-encoded signals using simple digital techniques is provided for use in an inexpensive Manchester-encoding receiver. The received Manchester-encoded signal is monitored to determine the zero-voltage crossing. At each such crossing the frequency of the recovered clock is adjusted by comparing the occurrence of the zero-crossing with respect to the midpoint of the period of the presently-generated recovered clock. Shortern, center or lengthen adjustment signals are generated as a result of this comparison which are used to shorten or lengthen, by 1/16 increments of the inter-bit period of the received data signal, the period of the next-generated recovered-clock. The method is readily implemented as a sixteen-state programmable counter providing a phase-locked loop.

Abstract: PURPOSE:To obviate large variation in amplitude absent in the original sound wave-form of decoded waveform by outputting a control signal associated with the generation of a carry signal or borrow signal to judge controllably whether or not a calculating output of an adder subtracter should be taken in by a register. CONSTITUTION:While amplitude data 103 and code data 104 are inputted to an adder-subtracter 6 to be outputted as calculating output 105, a gate control signal 106 formed by inverting a carry signal or borrow signal is outputted. The calculating output 105 is inputted to an X register 7, while a gate control signal 106 is sent to an AND circuit 10. A latch signal 107 for the X register 7 is also inputted to the AND circuit 10 and to the X register 7 only in the high level of the gate control signal 106 and DA converted in a DA converter 8 to be outputted as an analog signal 108. Thus, the generation of variation in amplitude absent in the original sound waveform of decoded wave form of ADPCM(Adaptive differential PCM) code is obviated.

Abstract: A multi-position ratchet mechanism for holding a surgical retractor blade (18) which permits a retractor blade to be rotated into the wound and retracted at the same time to duplicate the natural "toe-in" method of retraction achieved with the hand. The ratchet mechanism includes a ratchet holder (30) to which is pivotally attached a ratchet pivot housing (32). The retractor blade is mounted in an opening (42) projecting through ratchet pivot housing and held in position by a retractor pawl (44) attached to the ratchet pivot housing. The ratchet pivot housing also has a curved ratchet (68) which depends into a cooperating slot (70) in the ratchet holder and engages a ratchet release bar (80) which is mounted on the ratchet holder and spring biased into the ratchet slot. One end of ratchet release bar is positioned under an actuating surface (52) of the retractor pawl. The application of pressure on the actuating surface will release both ratchets to allow adjustment of the retractor blade.

Abstract: PROBLEM TO BE SOLVED: To reduce unevenness in color to be generated by the variation of contrast and brightness in plural picture components which is to be caused by the orientation dependence of the optical characteristic of a liquid crystal panel in a projection type display device. SOLUTION: When light irradiated from light source 55 is made to transmit toward upward as shown in the figure by arranging optical compensating plates 51, 52 at both sides of the front and rear sides of a liquid crystal panel 10 consisting of transparent substrates 11, 12 and the liquid crystal layer sealed in between them, and arranging two polarizing plates 53, 54 at the outside of the layers 51, 52, the optical orientation dependence of the display device is largely reduced as compared with that in the case of constituting the device only with the liquid crystal panel 10 and polarizing plates 53, 54. Thus, at the time of composing picture components in the projection type display device, even when mirror inversion among picture components is generated, the unevenness in color of a composite picture is suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a wheel cylinder piston for a drum brake, having an outer shape which is under formable in manufacturing and capable of being produced at a low cost. SOLUTION: Since the sidewall of a shoe receiving member fitting hole 30 for mounting a shoe mounting member is formed into a knurled shape, deformation of projecting parts of a knurling 31 is generated laterally and absorbed by recessed parts of the knurling 31, when the shoe receiving member is fitted in the shoe receiving member fitting hole 30, and therefore the outer shape of a wheel cylinder piston 20 is not deformed. Accordingly, since it is not necessary to form a deformation preventing counter shank on the wheel cylinder piston 20, the production process can be reduced. Also since it is not necessary to mount a preventing plate of eating into a boot for blocking the deformation preventing counter shank, the number of parts can be reduced, and the production cost can be reduced.
