Title: Read-out apparatus for solid state imaging device and image scanner using the same
Inventor: NAGANO FUMIKAZU
IPC: H04N1/19
Filed: 1991-02-26
Granted: 1996-04-23
Abstract: A read-out apparatus for a solid state imaging device has a plurality of photoelectric converter elements which convert an image into photoelectric charges and then store those photoelectric charges. The apparatus includes a shift register for shifting charges, transferred sequentially from the photoelectric converter elements to output image signals corresponding to the photoelectric converter elements. It also includes a gate for sequentially transferring the charges stored in the photoelectric converter elements to the shift register each time a transfer signal is applied thereto. It further includes a transfer signal generation unit for generating the transfer signal when an image signal corresponding to a predetermined one ofthe photoelectric converter elements is outputted. With this arrangement, charges in the shift register from one transfer operation from the photoelectric converter elements are partially overlapped with charges transferred in a previous transfer operation.

Title: Pour-in-place flexible polyurethane foam articles
Inventor: GILL WILLIAM A
IPC: B29C39/10
Filed: 1992-07-28
Granted: 1999-09-21
Abstract: It has been discovered that a particular polyurethane formulation may be used to prepare "pour-in-place" (PIP) polyurethane foam articles where the formulation is injected into a mold bearing an exterior covering such as a fabric without the foaming liquid striking through the layer. The formulation employs a hydrophilic polyhydric compound to help the reactivity balance that minimizes penetration of the exterior covering while also stabilizing the rising foam against shear collapse without excessively tightening the foam. Contrary to the conventional expectation that the hydrophilic polyhydric compound would, cause strike through problems since it delays the initial reaction time, it has been found to have the noted stabilizing effect. A preferred hydrophilic polyhydric compound is glycerine. A preferred isocyanate for the formulation is tolylene diisocyanate (TDI), in contrast to diphenylmethane diisocyanate (MDI) heretofore used in PIP foams.

Abstract: A method is provided for making a plurality of toothed belt constructions. The method comprises the step of disposing tubular sleeves of stretchable fabric material respectively onto a plurality of toothed mould members having different diameters. The method also includes the step of forcing mould material against outside surfaces of the sleeves to tend to stretch the fabric material into grooves of the toothed mould members as the mould material enters the grooves of the mould members, so that the resulting toothed belt means will have the fabric material thereof carried in certain positions relative to the respective teeth thereof. The method also includes the step of forming the sleeves from the same fabric material and with the same diameters in the non-stretched conditions thereof. The method also includes the step of forming the sleeves each to have a circumferential length in the fully-stretched condition thereof that is at least twice the circumferential length in the non-stretched condition thereof so that the fabric material is disposed substantially across the roots of the teeth of the toothed belt when the mould member being utilized at that time has a diameter that substantially corresponds to the diameter of the sleeve in the fully stretched condition thereof. The fabric thus substantially lines the outer peripheral surfaces of the teeth of the toothed belt means when the mould member being utilized at that time has a diameter that substantially corresponds to the diameter of the sleeve in the non-stretched condition thereof.

Abstract: An improved device, which uses cold red and infra-red radiation for the photodynamic stimulation of cells, specially cells of human tissue. The described improved device produces a constant energy radiation by help of semiconductor- and/or laser - diodes, which furthermore radiate light in more separate wavelengths due to a special operation mode. With help of sensors the advanced controller-system is able to test the patients for the needed radiation doses in order to avoid over-stimulation. Furthermore the radiation openings in the applicators are advantageable covered of a polarisation filter, whereby the absorption of the irradiated tissue is increased. The basic equipment consists of a moveable stand, with which machine-applicators are connected with a joint-arm. The machine-applicators are invented for the treatment of large area tissues, for example, the back of humans. The stand freely moveable on wheels consists of a control mechanism, whereby the different needed data for therapy can be adjusted and switched ON and OFF. The moveable stand is also connected with a hand-applicator designed for the treatment of small tissue-areas, e.g. acupuncture points. Another version of hand-applicator is especially invented for dental treatment, whereby the head-piece of the hand-applicator can be connected with an expander containing an optical fiber. 16~

Abstract: An improved outdoor lighting system is provided that comprises a light assembly formed from at least one tubular mast having a distal end for supporting an electrically powered light source, and a proximal end mounted in the ground, and an electrical cable for connecting the light source to an underground power source. The improved system includes an electrical connector assembly in the cable located in the vicinity of the ground-mounted distal end of the tubular mast. The electrical connector assembly spontaneously disconnects in response to an application of an tensile force indicative of an automobile collision with the mast, thereby preventing damaging tensile forces from being transmitted along the underground portion of the cable to the circuit breaker. The system further comprises an underground fuse assembly and lightning arrestor, both of which are mounted in an underground box electrically connected between the circuit breaker, and the underground portion of the cable that terminates in the aforementioned connector assembly. The remote, underground location of the fuse assembly and lightning arrestor provides easy and safe access to these components by maintenance personnel while discouraging vandals from tampering with or stealing these components.

Title: Maltose-trehalose converting enzyme, and preparation and uses thereof
Inventor: NISHIMOTO TOMOYUKI
IPC: A23L15/00
Filed: 1994-07-19
Granted: 2007-08-14
Abstract: An enzyme, which has a molecular weight of about 57,000-120,000 daltons on SDS-PAGE and a pI of about 3.8-5.1 on isoelectrophoresis using ampholyte, converts maltose into trehalose and vice versa. The enzyme was isolated from microorganisms of the genera Pimelobacter, Pseudomonas and Thermus. By using the enzyme, trehalose is readily formed from a commercially available maltose in an industrial scale and a relatively-low cost. Trehalose and saccharide compositions containing the same, which are preparable with the enzyme, are suitably used in food products, cosmetic compositions and pharmaceutical compositions.
