Title: On-vehicle position computing apparatus
Inventor: SHIBATA AKIHITO
IPC: G01C21/00
Filed: 1992-09-14
Granted: 1996-12-03
Abstract: High degree of accuracy of the position of a vehicle can be ensured by maintaining the continuity of the running path of the vehicle and by correcting the vehicle position to a vehicle position measured by a GPS navigation system when an positional deviation occurs due to sensor errors.  Specifically, the vehicle posi-tions are estimated in accordance with signals from sensors for detecting behaviors of the vehicle, and then the vehicle position is shifted onto a designated road having a feature coincident with that of the running path of the vehicle based upon data of the estimated vehicle positions.  Further, the vehicle position is corrected to a position measured by use of a GPS receiver only when the cumulative value of distances of the positional shifts made by a number of cycles in past or in a predetermined running distance range exceeds a predetermined threshold value.

Title: Polyoxypropylene/polyoxyethylene copolymers with improved biological activity
Inventor: EMANUELE R MARTIN
IPC: A61K31/765
Filed: 1992-03-18
Granted: 2004-02-10
Abstract: The present invention comprises novel preparations of polyoxypropylene/polyoxyethylene copolymers which retain the therapeutic activity of the commercial preparations, but are substantially free from the undesirable effects which are inherent in the prior art preparations. The preparation entails first condensing propylene oxide to produce a polyoxypropylene polymer and then condensing ethylene oxide with the polyoxypropylene polymer to produce a polyoxypropylene/polyoxyethylene block copolymer of the general formula:      HO(C2H4O)b(C3H6O)a(C2H4O)b H wherein a and b are integers. Because the preparations of polyoxypropylene/polyoxyethylene copolymers which comprise the present invention are a less polydisperse population of molecules than the prior art polyoxypropylene/polyoxyethylene copolymers, the biological activity of the copolymers is better defined and more predictable. The polydispersity of the copolymer is very low, average less than 1.07.

Title: Local oscillator and its frequency switching method
Inventor: SASAKI YUTAKA
IPC: H03B21/02
Filed: 1993-10-04
Granted: 1997-06-03
Abstract: A local oscillator and its frequency switching method, in which  local signals with  less  spurious components can be obtained.   There are provided with frequency generators for generating signals with different frequencies and frequency dividers respectively connected to the generators. The dividers divide in frequency the signals to output them in an active mode, and output the signals without division in inactive mode.          The dividers are controlled so that one of the dividers is in the active mode and the rest is in inactive mode.  The output signals from the dividers are combined with each other to form a single output current and then is sent to a filter.   The filter selects a component with a desired local frequency from the single output signal. Spurious components due to unselected frequencies are removed by the filter since they are not divided.

Granted: 1998-04-28
Abstract: A contact lens cleaning and disinfecting system is formed as a compact unit with an upper housing portion (1) containing a UV lamp and a lower base portion (2) containing a cleaning/disinfecting chamber (15, 16) which is filled with saline solution, a lens holder (14), a turbulence mechanism (17, 19, 20a) for inducing turbulence in the fluid, and an electronic control unit (21) for operating the UV lamp and the turbulence mechanism in a single cleaning/disinfecting cycle of comparatively short duration. The lens holder (14) has a pair of lower lens holder portions (14a, 14b) for the lenses and an upper bracket (14c) for shading the lenses from direct UV radiation. The turbulence mechanism has a magnetic pedal (20a), tethered on the end of a flexible spring (20b). The pedal is driven by a magnetic flux generator (19) in a subsonic oscillation range to create a whirlpool in the fluid which swirls in and around the lens holder portions. Particles, films, and other deposits dislodged from the lenses are carried by the whirlpool above the upper bracket of the lens holder where they are disinfected by the UV radiation. The UV disinfecting and turbulence cleaning avoids the need for any manual scrubbing, heating of the lenses, detergents, preservatives, or disinfectant chemicals.

Title: Seat belt retractor
Inventor: NAKAYA HIDEKAZU
IPC: B60R22/42
Filed: 1993-09-07
Granted: 2005-04-05
Abstract: This invention relates to locking means of a seat belt retractor equipped with an emergency lock which in an emergency locks the withdrawal of webbing.      The locking means of this retractor comprises a ratchet wheel (16) and a pawl (32); the pawl comprises two teeth, and the pawl and the ratchet wheel are positioned in such a way that when the load on the webbing is relatively small only one of the teeth of the pawl engages with a tooth of the ratchet wheel and there is a small gap between the other tooth of the pawl and the tooth of the ratchet wheel corresponding thereto and when the load on the webbing is relatively large both of the teeth of the pawl engage with teeth of the ratchet wheel.      As a result, because the load on each tooth is half of what it is when the pawl has one tooth only, twice the torque can be withstood and the diameter of the ratchet wheel can be reduced.

Abstract: A data compression system greatly compresses the stored data used by a speech recognition system employing hidden Markov models (HMM). The speech recognition system vector quantizes the acoustic space spoken by humans by dividing it into a predetermined number of acoustic features that are stored as codewords in a vector quantization (output probability) table or codebook. For each spoken word, the speech recognition system calculates an output probability value for each codeword, the output probability value representing an estimated probability that the word will be spoken using the acoustic feature associated with the codeword. The probability values are stored in an output probability table indexed by each codeword and by each word in a vocabulary. The output probability table is arranged to allow compression of the probability of values associated with each codeword based on other probability values associated with the same codeword, thereby compressing the stared output probability. By compressing the probability values associated with each codeword separate from the probability values associated with other codewords, the speech recognition system can recognize spoken words without having to decompress the entire output probability table. In a preferred embodiment, additional compressian is achieved by quantizing the probability values into 16 buckets with an equal number of probability values in each bucket. By quantizing the probability values into buckets, additional redundancy is added to the output probability table, which allows the output probability table to be additionally compressed.

Abstract: A variable proportion dispenser (2c) includes a housing (12c) which houses two pharmaceutical cartrides (6b). A reciprocating drive assembly includes drive stems (36c) extending from the pistons (46b) of each cartridge, a limit guide (76c) removably mounted to the housing, and a sliding body (66e, 300) mounted to the housing through the limit guide. Two one-way drivers (326) and threaded dosage adjusters (60c) are carried by the sliding body. Each one-way driver drives the drive stem into the cartridge through a drive surface to provide a range of dose selections. The user can thus control the amount and proportion of each pharmaceutical dispensed during each delivery stroke for each dispensing cycle. The housing is separable from the remainder of the dispenser, preferably using a cartridge release assembly (302), to allow spent cartridge to be replaced. Use of the cartridge release assembly also causes the one-way drivers to release the drive stems to permit the drive stems to be returned to their original positions.
