Abstract: A ball bearing for linear motion which is particularly useful in applications where the "open type" ball bearing is in combination with a shaft supported along its length which is subjected to radial forces primarily toward or away from the open side of the bearing. The ball bearing for linear motion consists of a bearing sleeve adapted to position a plurality of bearing segments on its inside surface. Each bearing segment contains a closed loop of circulating balls. The closed loop has one straight track of load bearing balls and one straight track of non-load bearing balls. The bearing segments are circumferentially positioned within the bearing sleeve so as to maximize the capacity of the bearing when load is applied either toward or away from the open side of the bearing.

Abstract: Induction heating is used to heat a moving strip (4) of non-ferrous material by causing it to form a short-circuited loop acting as a secondary winding of a transformer (1), the loop passing pulleys (6, 9, 16). The lengths of material which are incoming and outgoing to and from the loop are on the inside and outside of the loop. For the strip on the inside of the loop to connect with the exterior without further contact with the loop, an insulating spacing member is located between the loop and that strip, preferably by maintaining that strip out of the plane of the loop. <IMAGE>

Abstract: The invention provides a preparation of tumor cell lines containing an exogenous gene encoding a polypeptide that potentiates the immune response to the tumor, for example, interleukin-2. The invention includes methods for cancer therapy by immunization with the immunopotentiating tumor cell. The invention also provides methodology whereby one can selectively ablate in vitro and in vivo genetically altered cells. A preferred embodiment of this aspect of the invention includes a cell containing a first exogenous gene encoding an immunopotentiating polypeptide and a second exogenous gene encoding a "lethal" or "suicide" polypeptide, preferably under the control of an inducible promoter. Introduction of the second exogenous gene confers the ability to selectively kill the tumor cell by inducing a promoter in operative linkage to the gene encoding the lethal polypeptide to initiate transcription of the polypeptide. Diphtheria toxin or the thymidine kinase of Herpes simplex virus are exemplary lethal genes. An exemplary promoter employed is the 6-16 promoter, which is inducible with low levels of interferon. Methods for using the cells in cancer therapy are also provided.

Abstract: A system for subband coding of a digital audio signal x(k) includes in the coder (1) a filter bank (3) for splitting the audio signal band, with sampling rate reduction, into subbands (p = 1, ....P) of approximately critical bandwidth and in the decoder (2) a filter bank (5) for merging these subbands, with sampling rate increase. For each subband (p) the coder (1) comprises a detector (7(p)) for determining a parameter G(p;m) representative of the signal level in a block (p;m) of M samples of the subband signal xp(k) as well as a quantizer (8(p)) for adaptively block quantizing this subband signal in response to parameter G(p;m), and the decoder (2) comprises a dequantizer (9(p)) for adaptively block dequantizing the quantized subband signal sp(k)in response to parameter G(p;m). The quantizing characteristics are related to the noise-masking curve of the human auditory system, owing to which a high-quality of the replica x/< ANd >(k) of audio signal x(k) is attained with an average number of approximately 2.5 bits per sample for representing the output signals of the coder (1). The occasional audibility of quantizing noise in this replica x/< ANd >(k) is reduced effectively in that the coder (1) and decoder (2) contain identical bit allocation means (23, 24) responsive to a set of parameters G(p;m) for the higher group of subbands (pim</=p</=P) within an allocation window (Fig. 5) for allocating a number of B(p;m) bits per sample from a fixed predetermined number of B bits for this allocation window to the quantizer (8(p)) and the dequantizer (9(p)) for the block (p;m) of subband signal xp(k) and sp(k), respectively.

Abstract: PROBLEM TO BE SOLVED: To provide an encoder maximizing calculation accuracy while ensuring real time performance. SOLUTION: An audio signal is inputted to reset a timer (S1). The frequency of the audio signal is divided into 32 frequency bands (S2) so as to calculate a scale factor (S3). Then a masking level where a processing time is fluctuated based on a signal is calculated (S41) and whether or not a timer value is higher than a reference value is judged (S42). When judged to be higher than the reference value, masking level conversion processing in the step S43 is conducted. When not, the processing of the step S44 is conducted. In this case, the processing in the step S43 is conducted at low accuracy but its processing time is short. On the other hand, the processing of the step S44 is conducted at high accuracy but its processing time is long.

Abstract: PURPOSE:To improve the communication efficiency and to decrease an error rate by approximating the distance between a base station and a mobile station based on a received input level loss and calculating a phase lag so as to match a phase of the input signal with a phase of a standby clock. CONSTITUTION:An input level detector 27 of a base station 2 detects an input level of a received signal and discriminates it to be an input signal when the input level exceeds a predetermined threshold level and to be noise when less than the threshold level and uses an input signal/clock control section 28 to interrupt the input signal to a MODEM 23 in the case of noise. Furthermore, the input signal/clock control section 28 approximates a distance with a mobile station 3 based on the strength of the input signal level and calculates a phase delay of the input signal based on the distance and delays a demodulation reference clock 29 by the delay. Through the operation above, the demodulation reference clock 29 whose phase is almost coincident with the phase of the input signal is fed to a demodulation MODEM 23 independently of the distance from the mobile station 3 and the phase of the input signal is matched with the phase of the standby clock.

Abstract: A demodulation frequency plan for use in a global positioning system (GPS) receiver, having three demodulation stages for L1 and L2 signal channels, in which identical local oscillator frequencies are used in the L1 and, L2 channels at each demodulation stage, to minimize phase error differences between the two channels. The third stage provides an output at an intermediate frequency high enough to carry the full information bandwidth, thereby simplifying digital sampling of the signal, which is also performed in the third stage. Sampling is performed at a high enough rate to facilitate subsequent conversion to baseband. Moreover, the sampling rate is a binary multiple of the intermediate frequency, and this binary relationship further simplifies conversion to baseband. <IMAGE>
