Title: Image information transmitter
Inventor: KOYAMA TAKAAKI
IPC: H04N19/00
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce pattern area and to reduce waveform distortion and noise by providing a CPU for controlling the operation of an entire transmitter and a field programmable logic array(FPLA) for controlling the respective constitutive circuits of the transmitter under the control of the CPU. SOLUTION: Each control circuit is composed of the FPGA. A source oscillating clock from an oscillator 3 is supplied through an FPGA 41 to an LSI and by providing a gate at the source oscillating clock to be inputted to the FPGA 41, control is performed for stopping the operating clock of the LSI according to an external control signal. Thus, the operation of all the LSI is stopped and power consumption can remarkably be reduced. Further, since more gates can be secured per package area in comparison with a discrete IC, the required package area can be reduced and since a signal line pattern between the respective circuits is wired inside the FPGA, the pattern area can be reduced.

Abstract: PURPOSE:To enable a stable and low resistance value to be maintained over a long period of time between a core and a holder by press-fitting the core welded with a soft material having a high dielectric constant to the core holder. CONSTITUTION:The core 1 welded with the soft material having the high dielectric constant is press-fitted into the core holder 3 provided with a groove slightly narrower than the core width. Consequently, all of the three surfaces, front surfaces, side surfaces and base surfaces of the core 1 and the holder 3 can be securely and tightly adhered. The extremely low and stable resistance value is thus exhibited between the core 1 and the holder 3.

Title: Minute dimension measuring method
Inventor: KATOU TADAO
IPC: G01B15/00
Filed: 1978-11-06
Abstract: PURPOSE: To measure the dimensions of minute patterns high accurate and in excellent reproducibility from the central spacing of pulses, by extracting two pulses by differentiating minute pattern scanning image signals.  
     CONSTITUTION: Since fixed, electric detecting signals are obtained when scanning a pattern surface with minute patterns in sub-micron order by means of electronic beams in the a direction, two differential pulses are gained by the rise and fall of signals when the pattern surface is input to a differentiation circuit and differentiated. When measuring spacing in the fixed level value of each differential pulse, the dimensions of the pattern are acquired without being affected by noises.

Title: Self-aligning polysilicon contact
Inventor: KUOOFUA RII
IPC: H01L21/60
Filed: 1992-05-29
Abstract: PURPOSE: To provide a method for fabricating an integrated circuit in which a self-aligned polysilicon contact is formed. CONSTITUTION: A gate contact 19 to a field effect transistor is opened onto source-drain by forming a polysilcon plug 15 between a gate structure 5 having an uppermost nitride layer and a field oxide region 3. The contact 19 is formed by oxidizing and etching the gate structure 5 and the polysilcon plug 15. Since the oxidation rate is different for the material of polysilcon plug 15 and for the material of gate structure 5 in the former process, oxide layers of different thickness are formed and the gate contact is opened but silicon in the plug 15 is not exposed. Finally, the nitride is removed and the contact 19 to the gate structure 5 is formed.

Title: Automatic switching system
Inventor: SUGANO KEIKO
IPC: H04B1/74
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce a time for switching an active device and a reserve device on the occurrence of fault and to reduce an instantaneous interruption time during data transmission by confirming a mode in advance, immediately switching when a switch factor is generated in an active/standby system and performing mode confirmation processing by a factor generated afterward. SOLUTION: It is confirmed whether or not an alarm by a fault of an active system or the like is generated (S12). In the case of N(no), processing is shifted to S15. In the case of Y(yes), the active system where the fault occurs is automatically switched to a standby system, backed up and instantaneous interruption of a data transmitter is eliminated (S12). Next, a state of an active monitoring device is confirmed and the latest state is stored (S14). This S14 is finished and, in the case of N where the alarm does not occur in the active system, the processing of confirming whether or not it is an automatic switching mode is performed (S15). Therefore, if it is during automatic switching mode selection, a time needed until switching completion from the active system to the standby system can be reduced after fault occurrence of the active system.
