Title: Facsimile apparatus
Inventor: MOTOYANAGI TERUO
IPC: H04N1/00
Filed: 1991-08-19
Granted: 1995-12-12
Abstract: A facsimile apparatus capable of informing an operator of data such as operable time of the facsimile apparatus, the number of documents transmittable and receivable based on the quantity of electric charges remaining in the battery comprises a clock for generating time data and a monitor for monitoring the quantity of electric charges remaining in the battery.  The monitor calculates the charging time of the battery based on the time data.  The charged quantity of the battery from the time when the battery started to be charged to the cur-rent time is determined from the charging time.  The operation time of the facsimile apparatus driven by the battery in each of the operation modes is calculated based on the time data.  The consumed quantity of elec-tric charges in the battery is measured from the opera-tion time.  The quantity of electric charges remaining in the battery is calculated from the charged quantity and consumed charge quantity.  The operable time of the facsimile apparatus, the number of documents transmitta-ble and receivable for each of the operation modes are displayed based on the current quantity of electric charges in the battery.  A detector is provided which detects fall in the quantity of electric charges remain-ing in the battery below a predetermined value in a normal reception mode.  The operation mode of the facsim-ile apparatus is switched from the normal reception mode to a memory reception mode based on the output from the detector.

Title: Superconducting device having an extremely thin superconducting channel formed of oxide superconductor material and method for manufacturing the same
Inventor: NAKAMURA TAKAO
IPC: H01L39/14
Filed: 1991-09-27
Granted: 1998-04-14
Abstract: A superconducting device comprises a substrate, a projecting insulating region formed in a principal surface of the substrate, and a first thin film portion of an oxide superconductor formed on the projecting insulating region. Second and third thin film portions of an oxide superconductor are positioned at opposite sides of the projecting insulating region to be continuous to the first thin film portion, respectively, so that a superconducting current can flow through the first thin film portion between the second thin film portion and the third thin film portion. The second thin film portion and the third thin film portion has a thickness larger than that of the first thin film portion.  The projecting insulating region is formed of an oxide which is composed of the same constituent elements of the oxide superconductor but which has the oxygen content smaller than that of said oxide superconductor.     The superconducting device can be manufactured by forming on a surface of a substrate a compound oxide layer which is composed of the same constituent elements as those of an oxide superconductor but includes the oxygen amount less than that of the oxide superconductor, and which will be brought into an oxide superconductor when oxygen ions are injected, injecting oxygen ions into two separated portions of the compound oxide layer, so that the two separated portions of the compound oxide layer are converted into a pair of thick superconducting regions composed of the oxide superconductor, and heat-treating the layered structure in an oxygen atmosphere so that the oxygen is diffused into a portion of the compound oxide layer between the two separated portions of the compound oxide layer so as to constitute an extremely thin superconducting region.

Title: Method and reagent for determining specific nucleotide variations
Inventor: SOEDERLUND HANS
IPC: C12Q1/68
Filed: 1991-02-15
Granted: 2003-02-11
Abstract: Detection of variable nucleotide(s) is based on primer extension and incorporation of detectable nucleoside triphosphates. By selecting the detection step primers from the region immediately adjacent to the variable nucleotide, this variation can be de-tected after incorporation of as few as one nucleoside triphosphate. Labelled nucleoside triphosphates matching the variable nu-cleotide are added and the incorporation of a label into the detection step primer is measured. The selection of the detection step primer is important to the method according to this invention and is dependent on the nucleotide sequence of interest. The detec-tion step primers are preferably selected so to span the region immediately toward the 3' end from the variable nucleotide to be detected. The method is useful in identifying specific point mutations and genetic variations.

Abstract: A digital decoder for a biphase-mark encoded serial digital signal detects edges in the encoded serial digital signal by sampling with a sample clock to produce a blivet signal. The blivet signal is filtered by a one-bit digital lowpass filter (16) to recover a decoded clock signal and to generate a transition window signal. The blivet and window signals are used to detect whether there is a transition within each bit interval defined by the decoded clock signal. A decoded serial digital signal has a logical one for each bit interval in which a transition occurs, and a logical zero otherwise.
