Title: Stabilizer for a floating platen
Inventor: MERRIMAN RICHARD A JR
IPC: B41J11/02
Filed: 1991-10-21
Granted: 1996-05-28
Abstract: An apparatus for use with a print head which is used in conjunction with a floating platen.  The print head in mounted on a carriage which has a forms compensation member secured to it to contact the top surface of a document to be printed upon.  The forms compensation member causes the print surface of the platen to tilt somewhat causing ink smears or uneven printing by the print head.  A stabilizer is used to offset the tilting caused by the forms compensation member to thereby maintain the printing surface of the platen in parallel relationship with print face of the print head, which in the embodiment described, is a wire matrix printer.  The stabilizer includes first and second leaf springs which are secured to the platen and cooperate with a channel in which the platen is mounted.

Title: Y/c separation circuit
Inventor: UGAKI HIDEHIRO
IPC: H04N9/78
Filed: 1992-04-29
Granted: 2001-05-29
Abstract: A Y/C separation circuit includes a glass delay line for delaying an input composite video signal. A luminance signal and a chrominance signal are separated from each other by an adding circuit and a subtracting circuit each of which receives the input signal and an output signal from the glass delay line. The output signal from the glass delay line is phase-shifted by a 90° phase shifting circuit and then inputted to a multiplier which further receives the input signal. The multiplier outputs an error signal according to a phase difference between color burst signals included in the both signals, and a control voltage according to the error signal is outputted from a low-pass filter. The control voltage is applied to gyrators which terminate an input and an output of the glass delay line, respectively, whereby an inductance value of each of the gyrators is controlled by the control voltage such that a delay time of the glass delay line can be exactly adjusted at one horizontal period.

Granted: 1997-10-14
Abstract: The present invention relates to a self-diagnosing method which shortens the diagnosing time for a ROM which is provided within a mobile telephone set for use in a mobile telephone switching system and mobile telephone set being applied the method.  When the power supply is turned ON, a complementary value which complements to set up the sum of data stored  within all the addresses of the ROM as a certain specific value, ROMCHK, which is the content of the data stored within a specific address of the ROM, is compared with NVMCHK which is the content of data stored previously within a specific address of a non-volatile memory with the same value as the ROMCHK.  If they do not coincide, then the content of the data within the entire area of the ROM is calculated for the diagnosis.  In this case, the content stored within the specific address of the ROM is the sum of the data values within the entire area of the ROM, and the content stored within the specific address of the non-volatile memory is the same as this sum value.

Title: 4-cycle engine
Inventor: KAWAHARA YOSHITAKA
IPC: F02B3/06

Granted: 1997-03-25
Abstract: The known 4-cycle internal combustion engine including a crankcase, a cylinder, a cylinder head, a piston adapted to reciprocate within the cylinder, a combustion chamber formed by the piston, the cylinder and the cylinder head, and a crankshaft connected to the piston via a connecting rod, is improved in order to enhance a thermal efficiency, to lower an exhaust level of fuel and to make it possible to arbitrarily select-an operation attitude of a 4-cycle engine.  The improved 4-cycle engine comprises an intake passage and an exhaust passage provided in the cylinder head, a rotary valve rotating synchronously with the crankshaft at a speed one-half of that of the latter for communicating the intake passage and the exhaust passage with the cylinder respectively at the time of an intake stroke and at the time of an exhaust stroke, a check valve communicating the intake passage with a crankcase chamber to allow only a flow directed towards the intake passage, and fuel feed means for feeding mixture gas of air, fuel and lubricant oil into the crankcase chamber.          Thereby, suction of the mixture gas into the crankcase chamber as well as feed of the mixture gas into within the crankcase chamber to the intake passage are made possible by variation of the pressure within the crankcase chamber caused by reciprocating motion of the piston.

Title: Dual auger manure spreader having controlled beater feed
Inventor: FISCHER THOMAS R
IPC: A01C3/06
Filed: 1993-01-12
Granted: 1998-11-03
Abstract: A manure spreader device and method of distributing any of a variety of manure materials having varying consistencies are provided.  The device and method embody a concept in which a plurality of elongated augers that are longitudinally positioned within a translatable bin deliver manure material to an outfeed location for translation of the manure material to a beater assembly which distributes the manure material onto a field or the like.  A slippage characteristic is exhibited at the outfeed location whereby, when manure material within the outfeed location exceeds the expelling rate capacity of the beater assembly, slippage occurs between the manure material and rotating blades at the outfeed location so as to avoid overloading of the beater assembly by the particular manure material being spread.

Title: Optical resin materials with distributed refractive index, process for producing the materials, and optical conductors using the materials
Inventor: KOIKE YASUHIRO
IPC: C08F2/44
Filed: 1992-10-22
Granted: 2004-12-14
Abstract: An optical resin, of which the refractive index continuously changes in a specific direction, is produced by filling a polymerization container with a mixed solution containing at least one type of polymerizable monomer or polymerizable monomer sol and at least one type of substance whose solubility parameter differs by 7 (cal/cm3)1/2 or less and refractive index by 0.001 or more from those of a polymer produced by polymerization of the monomer, and by subjecting the mixture to polymerization reaction by applying heat or energy rays to the container from outside so that the polymerization reaction starts and progresses preferentially from a particular region of the mixture, thus forming a concentration gradient of the substance having different, refractive index.        The polymerization container may be made of a polymer which swells and dissolves into the mixed solution from an inner wall thereof.        After completing the polymerization reaction, the optical resin is subjected to hot drawing to obtain an optical conductor. Further, post-treatment based on crosslinking reaction is applied to improve heat resistance.

La partie principale de chaque procédé de décalage de canal utilisé par une station mobile dans une cellule ne présente de coïncidence sur aucun canal hertzien avec la partie principale de tout procédé de saut de canal utilisé par une station mobile d'une autre cellule. On évalue et on compare le rapport signal/interférence ou le taux d'erreurs binaires pour les signaux reçus par les stations mobiles, la puissance d'émission des stations étant régulée. On vérifie l'existence, dans une cellule, d'autres procédés possibles de sauts de canaux ne présentant de coïncidence sur aucun canal hertzien avec aucun autre des procédés de sauts de canaux déjà en utilisation dans cette cellule, et lorsqu'on désire établir une autre connexion à une station mobile particulière et qu'il existe un procédé possible utilisé par une station mobile ne présentant pas de coïncidence, la connexion désirée est établie à l'aide du procédé possible de saut de canal dans la cellule, uniquement si les valeurs C/I estimées pour certaines stations mobiles établissant entre elles des connexions dépassent un niveau minimum.

Abstract: A window balance system for a tilt sash uses a pair of constant force curl springs having curled convolutions carried by sash shoes and free end regions mounted in sash shoe channels above the region of travel of the shoes.  The recurl tendency of the springs imparts a lift to the curled spring convolutions, and the shoes transmit the lift to the sash.  The springs recurl into the convolutions as the shoes rise and uncurl from the shoes into the shoe channels when the shoes move downward, and neither movement requires the springs to slide frictionally within the shoe channels.  Each shoe is preferably formed of two identical halves that are assembled to trap the curl spring along with a cam that locks the shoe when the sash tilts.
