Title: Optical transmitter
Inventor: MATSUMURA KAZUO
IPC: H04B10/29
Filed: 1987-05-29
Abstract: PURPOSE:To avoid the breakage of an optical fiber part by using a 1st enclosure part which holds the electric signal input/output terminal part, a 2nd enclosure part which holds the optical signal input/output terminal part, and an optical fiber connector plug which is connected to the optical signal input/output terminal part freely attachably and detachably. CONSTITUTION:An optical fiber connector plug 5 attached with an optical fiber 6 is attached to an optical input/output terminal part 4. An electric signal input/output part 3 is held in the 1st enclosure part 1a and the part 4 is stored in the 2nd enclosure part 1b respectively. The part 1b is attached movably to the part 1a via a 1st attachment part 2a and a 2nd attachment part 2b. Thus the relative angle between both parts 3 and 4 can be optionally changed within a + or -90 deg. range. As a result, it is possible to avoid the breakage of the optical fiber part due to the installation of an optical transmitter and to improve the degree of freedom for installation of the optical transmitter.

Abstract: PURPOSE:To enhance searching and discriminating functions, by applying ON/ OFF control to a receiving radar pulse at a predetermined cycle using a delay wire. CONSTITUTION:A transponder is constituted of a transmitting-receiving antenna 1, a transmission/reception change-over switch 2, a microwave delay wire 3, a microwave amplifier 4 and an oscillator 5. The switch 2 has function cyclically connecting the output of the amplifier 4 to the antenna 1 on the basis of the control signal from the oscillator 5 and the cycle of the change-over control signal from the oscillator 5 is set so as to be sufficiently smaller than the pulse width of a receiving radar wave and determined so as to repeat transmission and reception plural (1/2 duty) times in said pulse width. The total delay time of the delay time of the delay wire 3 and the signal delay time in the amplifier 4 is set so as to coincide with the transmitting period determined by the control signal from the oscillator 5. By this method, the delay amplifying output of the radar wave received in each timing of a receiving period is transmitted from the antenna 1 in the timing of each successive transmitting period.

Title: Image recording device
Inventor: SAITO MINORU
IPC: G03D9/00
Filed: 1986-06-11
Abstract: PURPOSE:To attain uniform application of an image forming medium by increasing the driving peripheral speed of outlet side rollers higher than that of inlet side rollers. CONSTITUTION:The outlet side carrying rollers 56, 58 are rotated more rapidly than the inlet side carrying rollers 52, 54 and their driving peripheral speed is higher than that of the rollers 52, 54. Thereby, tensile force acts on a photosensitive material 16 by the driving peripheral speed difference, and when the tensile force exceed a prescribed value, the rollers 52, 54 are immediately slipped and their peripheral speed is made equal to that of the rollers 56, 58. Therefore, the rollers 52, 54 are rotated always in synchronism with the rollers 56, 58 and the photosensitive material 16 between the rollers 52, 54 and 56, 58 is carried with always constant tensile force and is not deflected. Consequently, water 46 is applied to the back surface (emulsion surface) of the material 16 by an application roller 44.

Abstract: PURPOSE:To obtain an optical recording medium having a high recording sensitivity, by causing a metallic thin film provided on a transparent resin substrate to comprise a platinum group element and other metallic or semimetallic element and to have a specified thermal conductivity. CONSTITUTION:A recording medium comprises a metallic thin film on a transparent resin substrate, which metallic thin film consists of a composition comprising a platinum group element as an essential constituent and other metallic or semimetallic element as an auxiliary constituent, has a thermal conductivity of not more than 80% of the thermal conductivity of the platinum group element alone, and is so conditioned that the reflectance thereof before recording in the case where laser light is incident thereon from the substrate side is 5-60%. When the optical recording medium is irradiated with laser light, generation of a gas arises from local decomposition of the transparent substrate to form voids, which lead to permanent deformations of the metallic thin film. Thus, permanent recording can be performed.

The detectors 3 and 13 detect the level of a burst signal from each slave station every time they receive a level detection instruction signal S3 of a discrimination processing circuit 100 and the detected signal is fed to the circuit 100. The circuit 100 discriminates the magnitude of the signal and transmits the result of discrimination to the SW as a selection signal S4 at the reception of the burst signal of the slave station of the next frame. The SW changes over the output to the receiver output of a high detection level with the signal S4 and supplies the burst signal of the next frame to a demodulator 110.

Title: Vector arithmetic processor
Inventor: SAKATA KUNIHIKO
IPC: G06F15/78
Filed: 1984-06-30
Abstract: PURPOSE:To attain application of the arithmetic pipeline processing even with execution of the vector operation with a mask and also to simplify the arithmetic error control when an arithmetic error is produced, by adding a zero detecting part and an OR gate to a division arithmetic part. CONSTITUTION:An arithmetic part Am is provided with a division arithmetic function together with a zero detecting part 42 which detects whether the 2nd operand (divisor) held by a buffer register 32m is equal to 0 or not and an OR gate 43. Thus the output of the arithmetic result is inhibited if a divisor (=0) or a division overflow of a fixed decimal point is produced in an execution mode of division using the pipeline processing. Then the 1st operand can be delivered through a vector control part M containing a mask in place of said arithmetic result. Thus the result of the constant 1st operand is obtained by producing an arithmetic error interruption after an output. This simplifies the control of interruption of an arithmetic error. In other words, the arithmetic pipeline processing can be applied. At the same time, the arithmetic error control processing can be simplified.

Abstract: PURPOSE:To reduce a head-positioning error when forming a core of a magnetic material film, by providing the core with an easy magnetizarion axis perpendicular to a magnetif medium surface at both terminals in a track width direction and a hard magnetization axis at its center. CONSTITUTION:Magnetic layer 1 is divided into three regions I-III; and in a method of giving magnetic anisotropy such as vapor deposition, regions I and III at both sides are formed in a direction (arrow P) perpendicular to track width W1, and region II is given an easy magnetization axis of width W2 in a track width W1 direction (arrow Q). This layer is formed with magnetic field application directions alternated by mask vapor deposition. In write operation, magnetic layers operate effectively in all regions I-III and reproduction is done in region II whose permeability is secured. In this way, the head positioning error of a high-density and narrow-track head is reduced to improve S/N, thereby reducing crosstalk.
