Title: Measuring method for coding characteristic
Inventor: HANATA TOSHIO
IPC: H04N17/00
Filed: 1979-08-28
Abstract: PURPOSE:To measure quantitatively coding characteristics of a traveling pattern by transmitting a stationary pilot signal and the traveling test pattern simultaneously and then by comparing the both to each other at a reception part. CONSTITUTION:Transmitted signal (a) includes stationary pilot signal 31 and traveling test signal 32 and slit widths W1 and W2 are set equal and varied. Then, slit width W1 of pilot signal 31 is measured when the difference between amplitude values h1 and h2 of two signals at a halfway point of the variation, so that up to what mus in slit width the transmission of a test signal can be carried out at speed v0 without deterioration will be measured. At the transmission part, the output data are inputted to the measured unit composed in eight-bit PCM data and at the reception part, outputs of dynamic-slit-amplitude measuring circuit 54 and fixed-slit- amplitude measuring circuit 55 are compared mutually. Then when the difference in amplitude reaches a certain value, the contents of fixed-slit-width measuring circuit 53 are read out and displayed by slit-width display circuit 57.

Inventor: ITOU KATSUJI
IPC: H01B7/282
Filed: 1980-08-08
Abstract: PURPOSE:To directly connect main circuit side and control circuit side, and to obviate the occurrence of flashover despite long-term use by applying insulation sheath on the outside circumference bundled with optical fibers, and providing a gas dam and a blast port to one end part of this sheath. CONSTITUTION:An optical fiber cable 1 is made by bundling prescribed number of optical fibers consisting of cores, clads and protecting coverings, and a plastic covering is applied on the outside circumference thereof. A gas dam 4 is formed in one end part 3A of the covering 3 of the cable 1. A dry air blast port 5 is provided to this part 3A, so that dry air can be fed into the cable 1. Hence, the pressure in the cable 1 is always higher than the outside, and this obviates the inclusion of moisture from the outside. As a result, a decrease in dielectric strength does not occur despite  direction connection of a main circuit on high voltage side and a control circuit on  low voltage side by means of the optical fiber cable, hence the occurrence of accidents such as flashover is obviated.

Title: Jig for inspecting continuity of printed wiring board
Inventor: KITAMURA TSUTOMU
IPC: G01R31/02
Filed: 1989-04-28
Abstract: PURPOSE:To achieve cost reduction and to enhance the reliability of inspection by using a metal foil having the same shape as the land of a printed wiring board but smaller than said land by about 50 mum in its respective dimensions as a continuity electrode. CONSTITUTION:Inspection is performed by a method wherein a jig and a printed wiring board are aligned and superposed one upon another to bring the continuity electrode 2 of the jig into contact with the land 6 of the printed wiring board and voltage is applied to the electrode 2 through the terminal of the jig by a continuity measuring device to measure a current value. At first, the electrode 2 has the same shape as the land 6 in contact with said electrode 2 but is smaller than said land 6 by about 50 mum in its respective dimensions, because the contact of the land 6 with the electrode 2 is not obstructed when the solder resist 7 of the printed wiring board is in a state running on the land 6. Further, the electrode 2 is formed using a copper foil or a gold plated copper foil. A lead part is formed using a copper foil and made lower than the electrode 2 so as not to obstruct the contact of the electrode 2 with the land 6. Next, the substrate of the jig is composed of a hard insulating plate.

Filed: 1992-04-28
Abstract: PURPOSE:To effectively suppress periodic noises picked up by microphone by subtracting periodic noises of a rotating body from the sound signals outputted from the microphone. CONSTITUTION:Sound signals are sampled at a sampling frequency which is an interger multiple frequency of the rotation frequency of a rotating drum and inputted to an averaging circuit 5. On the other hand, the data, which are written from a memory circuit 6 with the timing synchronized to the rotating period of the rotating drum and are written equivalent to one period prior to the rotating period of the drum, are read and inputted to the circuit 5. At the circuit 5, the averaged signals, which are the average of digital sound signals and the data read from the circuit 6, are obtained and are written into the addresses of the circuit 6. By this averaging process, the periodic noises, which are produced by mixing the sound signals picked up by a microphone 1 and the noises generated by the rotating drum, are extracted. The extracted signals are transmitted to a subtracting circuit 10 and subtracted.

Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable satellite communication line by providing a function for detecting a cut signal from a subscriber terminalside for a base station transmission/reception device. SOLUTION: When a subscriber terminal connected to an exchange terminates a call and it is on-hooked, a termination signal is transmitted from the exchange. In a station transmission/reception device 2, a sound signal detection part 30 of a modulation/demodulation part 20 detects the presence or absence of a sound band signal in the transmission side output part of a two lines/four lines conversion part 24 distributing/synthesizing transmission/reception signals into a transmission system and a reception system and transmits a detection signal to a timer part 31. The timer part 31 identifies the sound band signals (termination signals), which are continuously detected for the prescribed number of times in prescribed transmission time.  A control part 32 detects the terminating signal from the timer part 31, judges that the subscriber terminal is on- hooked and turns off a carrier transmitted from a transmission/reception part 21 to a facing station.

Abstract: PURPOSE: To heat blow of the drying bag passes through the space formed by the mattress and the drying bag body, and through the part consisting in the flow pathway in which the air passes inside the mattress. By doing so, the moisture of the mattress is absorbed and the moisture is discharged to the outside for improving the drying efficiency.

IPC: G06K7/10
Filed: 1994-05-24
Abstract: PURPOSE:To read out a bar code even when relative moving speed between a scanning line and the bar code changes. CONSTITUTION:When relative speed between a bar code and a scanner head is constant, data (b) corresponding to the data (a) of previous data exists on the reference position of current data found out by adding a moving distance to the coordinates of the previous data obtained one scanning before. Since the moving distance at the time of acceleration is longer than that of at a fixed speed and a moving distance at the time of deceleration is shorter than that of at a fixed speed, the corresponding data (b) are located before and after the reference position found out from the moving distance of the fixed speed. Thereby, a prescribed range around the reference position found out by adding a moving distance obtained by preceding measurement to the coordinates of previous data is set up as a retrieving range, the address of data of a bar existing in the retrieving range is retrieved and the positioning of data extracted as the same part is executed to synthesize extracting data.

Abstract: PURPOSE:To enable efficient separation of a frozen food from a container in frozen state without using heat, by transferring a freezing container with a transfer means in nearly horizontal direction and repeatedly pressing the container from above with a pressing mechanism. CONSTITUTION:A sprocket wheel 3 connected to a motor M1 is rotated in the direction (a) to drive an endless chain 33 in the direction A. A container 9 put into a transfer part 35 is pushed with a pushing rod 34 attached to the endless chain 33 with a transfer mechanism (b') and transferred nearly horizontally in the same direction. According to the approach of the container 9 to a part under a rotary cam 1 rotating in the direction of the arrow (b) of a pushing mechanism (a') accompanied by the transfer of the container, the pushing part 13 of the rotary cam 2 is lowered until the middle part of the container 9 reaches just below the rotary cam 1, when the bottom of the container 9 is pushed downward and deformed with a pushing part 13 of the rotary cam 1. The frozen food 92 attached to the bottom of the container is automatically separated from the bottom by the deformation of the container. The separated food is passed between rails 4, dropped on a conveyor C1 under the rails and delivered from the apparatus.
