Title: Drop-out position detector
Inventor: TOOMASU DANIERU KAA
IPC: G11B20/18
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To detect generation of a dropout in a data bit stream of a data block and a position thereof and set a flag at the position, by providing modified positive and negative detectors PPD and NPD as a peak detector. SOLUTION: A peak detector 64 in the device has a modified positive peak detector (PPD) 70 and a modified negative peak detector (NPD) 72. The PPD 70 and NPD 72 have comparators 92 and 94 and comparators 109 and 104, respectively. The comparators 92 and 109 compare a positive clock peak or data peak in an input read signal pattern with threshold levels CT + and DT. The comparators 94 and 104 compare a negative peak or data peak in the input read signal pattern with threshold levels CDT+ and DDT-. When the peak values of the read signal pattern the thresholds CT+ and CDT+, decoding of a dropout pulse DO+ is inhibited or invalidated, coding of only the effective peak detection pulse PD+ is allowed and supplied to a decoder.

Title: Telephone number informing system for line exchange system
Inventor: OZAWA YUJI
IPC: H04L12/66
Filed: 1991-04-16
Abstract: PURPOSE:To reduce the load of nodes at a line exchange system. CONSTITUTION:Nodes 101-106, directory service node 11 and line management node 12 are connected to a transmission line 14. The node 105 is connected through a public network 13 to the other transmission line. When a channel allocation request is generated for data transmission, the node transmits channel allocation request to the line management node 12 together with the destination information. When the channel allocation request is received, the line management node 12 refers to the destination information and returns a response by executing channel allocation when the destination is the node in the transmission line 14. In the case of the node in the other transmission line, however, the telephone number of the transmission line at the relevant destination is referred to by the directory service node 11. The line management node 12 transmits the telephone number obtained from the directory service node 11 to the node together with allocated channel information.

Title: Odor-measuring apparatus
Inventor: MATSUNO GEN
IPC: G01N29/02
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To measure an odor substance dissolved in a solution by a quartz oscillator-type odor sensor, by evaporating the odor substance contained in the solution, removing moisture and supplying the substances to the odor sensor. SOLUTION: An odorless dry air supplied to 100 by the operation of a flow path switch valve 4 is input to a sensor cell 5 and discharged through 101. An output signal from an odor sensor 6 is input in this state to a measuring circuit 7, thereby to calibrate a zero point by using the signal as a zero point signal. At the time of the measurement, the odorless dry air supplied to 100 by the operation of the flow path switch valve 4 passes through a solution 102 in a bubbling means 2. Only moisture in an output gas is transferred by a membrane-type drier 3 through a semipermeable membrane to the odor dry air supplied to 100a. The air is input to the sensor cell 5 via the flow path switch valve 4 and discharged through 101. In this state, a concentration of an odor substance is operated by the measuring circuit 7 based on the output signal of the odor sensor 6. The odor substance in the solution can be accordingly measured with the use of a quartz oscillator-type odor sensor, without increasing a humidity in the sensor cell 5.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To suppress the spread of umbrella cloth just by closing an umbrella and to prevent hands from getting wet by constituting the umbrella cloth between respective ribs by plural pleats. SOLUTION: The umbrella cloth 2 between the respective ribs 1 is worked into the plural pleats. The umbrella cloth 2 is turned to a wedge type shape radially spread from an umbrella shaft 3 to an outer end in an opened state. It is further divided by plural straight lines 4 from the umbrella shaft 3 to the outer end and folds are attached alternately to be a peak and a dent on the respective adjacent straight lines 4. As a result, the umbrella cloth 2 between the respective ribs 1 is turned to an accordion shape and turned to the state of being folded between the respective ribs 1 without being spread to an outer side in the state of closing the umbrella. The folds are formed by press-working the umbrella clock 2 or by sewing the umbrella cloth 2 cut at the straight lines 4 together by a high frequency sewing machine or the like.

Filed: 1983-05-17
Abstract: PURPOSE:To prevent cracking of a positive type photoresist film, peeling of it from a substrate, deterioration of its resolution, etc. by preventing bubbles from being involved between said film and a protective film in forming it. CONSTITUTION:A silicon wafer having a 1mum thick heat oxidized film is coated with a positive type photoresist to form a 1.5mum thick photoresist film, and further, it is coated with a soln. of polyvinyl pyrrolidone resin to form an about 1mum thick protective film. A photomask is brought into contact with this protective film and separated from this and this operation is repeated for 10 times and registered exactly. It is exposed to UV rays through the mask to transfer the prescribed pattern to the protective layer, and developed to form the resist pattern on a wafer. As a result, in forming the protective film on the resist film, bubbles can be prevented from being involved between both films.

Abstract: PURPOSE:To reduce number of control wires for recording an object in the electronic camera. CONSTITUTION:The exposure, sweepout of smear charge and read of signal charge are decided in advance within a prescribed period after production of a trigger signal TRG. When a recording switch 58 is depressed, the trigger signal TRG is outputted from a timing control section 55. Because of the production of the trigger signal TRG, the exposure, sweepout of smear charge and read of signal charge are automatically implemented after a prescribed period. Since each processing is not independently controlled, number of control wires is reduced.
