Title: Transformer coupling burst signal reception circuit
Inventor: IZAWA HIROSHI
IPC: H03K5/125
Filed: 1989-04-10
Abstract: PURPOSE:To receive a burst signal without losing the head of the burst signal even when the head of the burst signal is distorted by adding the output signal of a comparator receiving the burst signal to a transformer output and amplifying the result differentially. CONSTITUTION:A burst signal inputted to a transformer 3 is inputted to a differential amplifier 12 and inputted to a noninverting input of a comparator 8. Resistors 6, 7 are connected between the input terminal and the output terminal of the comparator 8 and a comparison reference voltage is obtained with resistance partial potential division ratio from the voltage and the output voltage of the comparator 8. Since an input signal voltage at an inverting input exists in the burst signal amplitude with respect to the burst signal inputted to the noninverting input of the comparator 8, the comparator output is outputted from the burst head bit. Thus, the signal inputted to a noninverting input terminal of the comparator 112 is a signal resulting from the superimposing signal between the output signal of the transformer 3 and the input signal from a coupling capacitor 11, and the amplitude is increased and received without loss of the head of the burst signal.

Title: Signal processing for determining base sequence of nucleic acid
Inventor: MINAMI TOMOYUKI
IPC: G01N27/447
Filed: 1986-04-19
Abstract: PURPOSE:To enable the obtaining of a base sequence of nucleic acid handily at a high accuracy, by finding one band nearest a searching start point from a signal level and a threshold thereof at the searching start point on a straight line along a separation/development direction for each of separation/development trains. CONSTITUTION:One band nearest a searching start point is found from a signal level ls and a threshold ln (n is 0 or positive integer) thereof at the searching start point on a straight line along a separation/development direction x for each of separation/development trains. After an area of this band is determined from the threshold ln, the band is determined to be true according to the size of the area to detect this band, or it is determined that this band is not true and the operation is redone. This enables accurate detection of bands without misrecognition of a noise such as extra band for a band or misreading of fusion band for a single band.

Title: Wire dot printer head
Inventor: SAGAWA MASATO
IPC: B41J2/285
Filed: 1981-06-15
Abstract: PURPOSE:To reduce the cost of a wire dot printer head by the adoption of a wire for printing image of which one end is fixed to one polar surface of a floatable permanent magnet and an iron core with an exciting coil having two poles which are arranged opposingly to each other so that the two poles of the permanent magnet are held pinched between them. CONSTITUTION:The non printing end of a wire for printing image 3 is vertically fixed to S polar surface of a permanent magnet 4. The wire 3 is caused to pass through a piercing hole formed in one pole of an iron core 1 so that it can be moved for printing. A nonmagnetic separating member is adhered to the bored polar surface. When the iron core is magnetized and the pole opposing to N pole of the permanent magnet is magnetized to N pole and the pole to which separating member 5 is adhered is magnetized to S pole, repelling force acts between opposing poles respectively, but the distance between N-N pole is shorter than that of S-S poles, therefore the permanent magnet 4 is driven in the direction of S pole and the wire 3 prints a dot.

Filed: 1988-04-13
Abstract: PURPOSE:To easily and continuously detect a low twisting strength part by providing a capstan roll and stationary spiral guides which impart twists to an optical coated fiber on the outside circumference of the capstan roll. CONSTITUTION:The optical coated fiber 1 is let off from a supply bobbin 8 and arrives at the point between the beginning end of the stationary spiral guides 6 and an inlet guide 7 via guide rolls 9 and is wound up on the outside circumference of the capstan roll. The optical coated fiber 1 on the outside circumference of the capstan roll 5 is rotated in the axial center direction of the capstan roll 5 by the effect of the stationary spiral guides 5, by which the twist is applied to the fiber. The stationary spiral guides 6 are fitted in proximity to the outside circumference of the capstan roll 5 on which the optical coated fiber 1 is wound and which feeds such fiber. Since these guides are fixed to a stationary system, the optical coated fiber 1 on the outside circumference of the capstan roll 5 is rolled in the axial center 5A direction of the capstan roll 5 and is given the twists successively in the longitudinal direction thereof by the effect of the stationary spiral guides 6, by which the continuous screening of the twist strength is easily executed.

Title: Optical deflector
Inventor: INOUE NAOHISA
IPC: G02F1/335
Filed: 1985-04-30
Abstract: PURPOSE:To obtain an optical deflecting device which can be coupled with an optical fiber efficiently and obtains high deflection efficiency by increasing the width of a light guide gradually toward a light guide layer. CONSTITUTION:The width of the light guide 16 is nearly as small (width D1) as core diameters of optical fibers 18a and 18b, etc., connected thereto on an end surface of a substrate and increases gradually to the light guide layer 12. Thus, the width of the light guide 16 is increased gradually to increase optical deflection efficiency. A light guide with a constant width of 4mum equal to the core diameter of the optical fibers has deflection efficiency less than 0.1, but the width of the light guide is increased gradually up to 40mum to increase the deflection efficiency by about 0.5 time. When the light guide increases in width gradually so that variation in the width of the light guide when a light wave travels by one wavelength is much smaller than one wavelength, no mode conversion is caused. The variation in the width of the light guide is preferably about 1% of the distance of one wavelength.

Title: Rotary head type reproducing device
Inventor: TANAKA MASATO
IPC: G11B20/10
Filed: 1990-04-06
Abstract: PURPOSE:To attain reproduction without high-accuracy tracking by scanning and reproducing recording tracks by the more number of rotary heads than the heads required for recording and reading a digital signal out of a memory according to reproduced address signals. CONSTITUTION:Recording tracks of the specific number of digital information signal blocks to which address signals are added are reproduced at the same rotating speed as that at the time of recording by using more rotary heads 2 and 2a than the rotary head 2 used for the recording. Therefore, while the magnetic tape 3 is fed by one track, the rotary heads 2 and 2a scan the magnetic tape 3 twice in total and the number of scans becomes larger than that at the time of recording, so the reproduction scan tracking pitch becomes smaller than the track pitch and >=1 reproduction scan track invariably passes each recording track without tracking. Then the reproduced digital information signal which is written in the memory is read out in specific order according to the reproduced address signals and made continuous. Consequently, the reproduction is performed without high-accuracy tracking.
