Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To automatically predict a chip size when completing the preparation of an IC circuit and to make compatible degradation suppression of chip size conditions and shortening of development turn-around time(TAT). SOLUTION: When an IC designer prepares a circuit diagram, respective circuit elements included in this circuit diagram are extracted, each element is converted to a reference integration enable number per unit packaging area of a basic element, a total packaged element number is calculated and the chip size is predicted from the data of layout and reference integration enable number (integration density) stored in a data base 40. Then, this predicted value is compared with a chip size based on an article plan and when it is within an allowable range, IC layout processing is started. When the chip size is not proper, redesign is performed. After layout in IC layout processing, the integration density is calculated from a real chip size and automatically stored in the data base 40.  Besides, the real chip size is compared with the chip size in the article plan and when it is within the allowable range, work is completed.

Title: Optical communication system in spacial transmission
Inventor: YAMADA KOHEI
IPC: H04B10/112
Filed: 1985-08-05
Abstract: PURPOSE:To reduce the variation of a transmitting state by executing communication through two optical transmission lines modulated by the same information. CONSTITUTION:A signal supplied from a transmitter to an input terminal 1 is distributed by a distributer 2 and supplied to two light emitters 3a, 3b. The light emitters 3a, 3b emit optical signals 4a, 4b modulated by the supplied signals and the optical signals 4a, 4b are transmitted through space and detected by photodetectors 5a, 5b. The optical signals detected by the photodetectors 5a, 5b are transduced into electric signals, the electric signals are added by a coupler 6 and the added signal is supplied to an output terminal 7. Since the optical signals 4a, 4b are transmitted through the completely different pathes, the probability of the simultaneous variation of the two transmission lines is reduced and the variation of the transmitting state can be reduced.

Abstract: PURPOSE:To prevent a seal ring from bulging out, wherein the ring is situated on the outside of a dust cover pinched by a housing and a bearing. CONSTITUTION:Through a bearing 20 a housing 30 supports a globe-form head 11 by allowing the shank 12 of a ball stud 10 to protrude from end openings 31 of this housing 30.

Title: Channel memory operation control system for time division switch
Inventor: ASANO KENICHI
IPC: H04Q11/04
Filed: 1986-07-23
Abstract: PURPOSE:To attain low power by storing idle/busy management information of an output channel in a 2nd storage means for designating the read address of a 1st storage means for storing digital information by one inputted frame to replace the channel and reading the 1st storage means in case of the occupied state only thereby reducing the operating rate of the channel memory of the time division switch. CONSTITUTION:A one-frame serial signal from input highways 100-107 is subjected to serial/parallel conversion at each channel by variable delay shift registers 130-137 and outputted to a selector 122 and fed to a speech path memory 120 while being selected sequentially. Then the read address is controlled by a control memory 121 to repace the channels. When information is written in the memory 120, the selector 124 selects a H-level fixed signal 127 and in case of data readout, the selector selects an idle/busy management bit 128 of the memory 121. AND gates 150-157 use the output of bit 128 and the memory 120 to bring all bits of idle output channels to a L level. Shift registers 140-147 apply serial convertion to parallel data being outputs of the memory 120 to apply output phase adjustment among output highways 110-117.

Title: Optical detecting device
Inventor: IWATANI TOSHIO
IPC: G01S17/02
Filed: 1981-10-27
Abstract: PURPOSE:To process a light receiving signal as it is a digital signal, by providing an oscillating circuit, which emits the lights impulsively, and a retriggerable monostable multivibrator which is triggered by the signal due to an AND circuit for AND between the light receiving signal and the light emission signal. CONSTITUTION:The output pulse signal from an oscillating circuit is inputted to an inverter N4 through a delay circuit consisting of resistances R7 and R8, a capacitor C2, and a diode D4, and the light reflected by a material P to be detected is received by a photodiode PD of a light receiving member and passes through an operational amplifier OP as a light receiving signal and is inputted to an NOR gate N6 after inversion of the H level and the L level. Both inputs have their delays cancelled, and no hazard is generated in the output of the NOR gate N6, and this output becomes a trigger input of a retriggerable monostable multivibrator N7. When the material P to be detected exists, this trigger input becomes retrigger inputs successively, and the output of the monostable multivibrator N7 becomes a continuous waveform. When the material P to be detected does not exist, the signal disappears after a delay of a time tl+n, and thus, the output state of the monostable multivibrator N7 is detected to discriminate whether the material P to be detected exists or not.

Abstract: PURPOSE:To avoid a defect due to a temporal interpolation filter in the case of receiving signals without correlation between frames without losing the substantial function by providing a means controlling an output of a coefficient device to zero if no correlation exists between frames. CONSTITUTION:A cyclic filter 50 consists of an adder 34 receiving a high frequency component, a frame memory 35 receiving an output of the adder 34, a subtractor 36 applying the subtraction processing between the output of the frame memory 35 and the high frequency component, and a coefficient device 37 multiplying a coefficient with the output of the subtractor 36 and giving the output to the adder 34. Furthermore, means 4, 5 are provided in addition, which detect whether or not correlation exists in corresponding signals between frames of an input picture and control the output of the coefficient device 37 to zero in the case of no correlation existing between frames. Thus, when there is almost no correlation between frames, since the coefficient of the coefficient device in the cyclic filter is zero, a defect due to temporal interpolation is prevented and the substantial function of the temporal interpolation filter is sufficiently enhanced in the normal operation.
