Title: Semiconductor logic integrated circuit
Inventor: SESHIMO TOSHIKI
IPC: H01L21/82
Filed: 1989-08-31
Abstract: PURPOSE:To obtain a high-performance logic integrated circuit using an SLCF circuit by facing the pattern layout of a Schottky junction diode toward a cathode region so that the anode region faces the part that is 1/2 of the periphery of the cathode region. CONSTITUTION:An n-type active layer 2 having an approximately square shape is formed in a semi-insulating GaAs substrate 1 by, e.g. Si-ion implantation. An anode electrode 3 as a key-shaped Schottky gate electrode is formed on the layer 2 other than one corner at the lower right side. A cathode electrode 2 which is an ohmic electrode is formed in a square shape at the lower right corner of the n-type active layer. Namely, the layout of the anode electrode 2 constituting the Schottky junction is formed so that the electrode 2 faces two sides of the four sides of the cathode electrode 4, in other words, the part that is 1/2 of the periphery of the cathode electrode 4. In this way, the concentration of currents at the end of the gate due to the lateral resistance of the n-type active layer and the decreases in effective junction capacitance caused by said concentration can be suppressed. The high speed property inherent to an SLCF (Schottky-diode-Level-shifter-Capacitor coupled FET Logic) circuit can be obtained.

Filed: 1990-08-23
Abstract: PURPOSE:To reduce the deterioration of picture quality at the time of system conversion by providing an average circuit averaging signals between two lines of a chroma signal to be ouputted from a chroma modulation circuit. CONSTITUTION:A chroma demodulation circuit 2 is connected to an input terminal, and a R-Y color difference signal and B-Y color difference signal are respectively supplied to low pass filters 3 and 4 to be converted into time division multiplexation through a multiplexer 5. By continuing the signal of a field memory at the time converted into the division multiplexation by the multiplexer 5 and converting them into analog signals respectively by D/A converters 9 and 10, the R-Y and B-Y signals of a NTSC system are respectively obtained. This signal is modulated by a chroma modulation circuit 11 and supplied to an 1H delay circuit (1HDL) 13. An adder 14 constitutes an average circuit 15 averaging the output of two horizontal scanning lines of the chroma signal by adding the input signal and the output signal of the 1H delay circuit 13. Thus, line flicker noise likely to be generated when modulating the chroma signal can be prevented.

Title: Data collection system
Inventor: ASAI TAKAHIRO
IPC: H04L12/40
Filed: 1982-12-20
Abstract: PURPOSE:To collect data efficiently through a simplified system constitution by sending one-bit data from the terminal farthest from a data collecting device, and sending received data by adding each terminal together with one-bit data. CONSTITUTION:The system wherein plural terminals 2 are connected in a line through a unidirectional transmission line 3 and each terminal sends a little data to the data collecting device sends one-bit data #1 from the terminal farthest from the device 1. The logic 1 and logic 0 of data are shown by a wide and a narrow pulse respectively, and the one-bit length of the data is Tb. The terminal which is second to the farthest terminal receives the pulse #1 and sends the pulse while adding its one-bit data #2 to the end of pulse. Thus, respective terminals send received data to the device 1, one after another, together with their data added to the end of received data. The device 1 discriminates that the data is sent from which terminal according to the order of a received pulse train. The farthest terminal sends the data with a period much longer than the overall data length NTb.

Title: Method of picking up laminated cloth
Inventor: MIYAUCHI TAKASHI
IPC: B65H3/00
Filed: 1984-10-24
Abstract: PURPOSE:To maintain conformity of laminated cloth left in standby position by setting the trailing edge of cloth fixed in a given position without any movement during the period of pulling up the cloth slant upward at a constant speed and a constant angle with respect to the surface of a table with its leading edge grasped. CONSTITUTION:The leading edge portion A of the upper most cloth layer 22a of the laminated cloth 22 placed on a table 20 is held by some proper gripper means. The cloth 22a is pulled up slant upward along a dotted line 18' busing this gripper means at a constant angle alpha with respect to the surface of the table 20 and at a constant speed. Then, only downward gravitational force is generated at the trailing edge B of the cloth 22a and point B stands still. When the leading edge A comes to position A', the trailing edge B' is separated from the surface of cloth 22b causing the cloth 22a to be perfectly hung down. Accordingly, the trailing edge B of cloth 22a stays in a fixed position during upward peeling off action on this cloth 22a which gives no effect on the cloth 22b staying just below, thus conformity of the laminated body 22 being maintained.

Title: Polarizing device
Inventor: ICHISE HARUNOBU
IPC: G03B5/00
Filed: 1992-08-24
Abstract: PURPOSE:To reduce the front projection area of a driving means and to drive the device with a small power consumption by arranging the driving means so that it protrudes almost in the direction of the optical axis. CONSTITUTION:Transparent liquid is held by a transparent flat plate and bellows 5 fitted to holding frames 3 and 4 respectively to constitute a variable apex angle prism. An actuator member 9 is fitted integrally to the holding frame 3 at a right angle to the plane formed of the holding frame 3 and transparent flat plate. Then, the actuator 9 is rotated around a rotation axis 3a-3b by controlling a current supplied to a coil 9b to rotate the holding frame 3, thereby deflecting incident luminous flux in the right-left direction. Actuators 18 and 19 are rotated around a rotation axis 4a-4b to deflect the incident luminous flux in the up-down direction. This constitution is similar to the actuator units 8 and 9. Consequently, the actuator units are stored behind the variable apex angle prism to reduce the front projection area.

Title: Magnetic position/rotation detecting element
Inventor: ONAKA KAZUHIRO
IPC: G01R33/09
Filed: 1993-09-09
Abstract: PURPOSE:To allow a detecting element to be miniaturized while increasing the output by arranging the signal field from an object to be detected in parallel with the longitudinal direction of a magnetosensitive pattern. CONSTITUTION:A signal field 6 from an object to be detected, a pattern 7 at a magnetosensitive part, a pectinated route 8, etc., are provided. The width W of pattern at the magnetosensitive part is determined according to a formula; Hk=Ha+4piIs.T/W, where Hk: saturation field of element, Ha: essential saturation field of magnetic film, Is: saturation magnetization, T/W: reverse field constant. The pattern width W contributes significantly to HK. When the pattern width W is decreased, the HK decreases and the magnetic sensitivity increase. Consequently, when the sensitivity is increased by decreasing the HK, the magnetosensitive pattern width decreases and the resistance of element increases and thereby, the pattern describing range is limited for the same design resistance.

Abstract: PURPOSE:To suppress jitter of a rotary magnetic head to perform good magnetic recording by setting the servo gain of a rotative velocity controlling servo mechanism of the rotary magnetic head to a large value to obtain a control progress with rather unsatisfactory damping if a ratio of frame omission is high but setting said servo gain to a small value if said ratio is low. CONSTITUTION:A parallel connection circuit of two resistances R and (r) which are the feedback resistances of a servo amplifying circuit 13 is provided in a gain adjusting circuit 15, and the resistance (r) is opened or closed in accordance with switching of a switch 17 connected in series to the resistance (r). That is, the feedback resistance for closing of the switch 17 is lower than that for opening of the switch 17, and the gain of the servo amplifying circuit 13 is reduced by this difference when the switch 17 is closed. Switching of the switch 17 is controlled by the detection signal of a frame omission ratio detecting circuit 18; and if the ratio of frame omission is low, the switch 17 is closed to set the gain of the servo amplifying circuit 13 to a small value. If the ratio of frame omission is high, the switch 17 is opened to set the gain of the servo amplifying circuit 13 to a large value.
