Title: Low hardness conductive rubber roller
Inventor: TANIFUJI HIROSHI
IPC: B65G39/07
Filed: 1982-07-06
Abstract: PURPOSE:To secure such a roller as being low in hardness and excellent in conductivity, besides nonstickly as well as to make a clean-cut picture securable, by compounding a proper amount of plasticizer and carbon black into specific base rubber available for printing rollers of a facsimile. CONSTITUTION:This roller is produced by the way of covering a rubber composition, whose main ingredient consists of norbon polymer 100pts.wt. plasticizer 100-250pts.wt. and carbon black 30-150pts.wt., over a roll core shaft, then heating and bridging it. In addition, these components are well mixed and kneaded by a Banbury mixer or a kneader, and made up in a sheetlike form carrying a thickness of 5-10mm. or so by means of an oven roll. After the roll core shaft is covered with this sheetlike compound, it is heated for 20-40min long at a temperature of 130-160 deg.C as well as at a pressure of 100-150kg/cm<2> by using a metal mold and bridged. After doing like this, with the bridged one well ground to the extent of the specified size, a low hardness conductive rubber roller can be secured.

Title: Method for measuring impurities
Inventor: SHIMIZU YASUSHI
IPC: G01B11/28
Filed: 1992-05-11
Abstract: PURPOSE:To measure impurities irrespective of the surface state of a surface to be measured by measuring difference signals outputted by calculating the difference between signals inputted upon receiving the image of reflected light from the surface when the surface is irradiated with white light and a threshold signal with a pulse counter. CONSTITUTION:After a sample 1 to be measured is closely set to a piece cover glass 2, the glass 2 is fixed to a fixing section 3. When the sample 1 is irradiated with white light from a light source 4, a picture having no background noise is obtained even from a sheet having a bad surface condition. A CCD camera 5 takes a reflected picture and sends video signals to a signal processing circuit 6. The circuit 6 generates a signal voltage, such as the average level phase of reflected light, etc., by reducing impurity signals from the video signals with an LBF 10 and a voltage dividing circuit 11 divides the voltage and supplies the divided voltage to a comparator 12 as a threshold signal. The voltage dividing ratio of the circuit 11 becomes the setting criterion of the circuit 6 and constitutes an impurity discrimination circuit. Therefore, the area of impurities can be found by counting the number of clock pulses with an ' counter 15.

Title: Apparatus and method for synchronization,in zero waiting time,with system provided with at least two clock domains
Inventor: ARAN SHII ROJIYAASU
IPC: G06F1/12
Filed: 1995-04-20
Abstract: PURPOSE: To securely transfer data between clock domains without delay by guiding unstable settling delay to a clock route. CONSTITUTION: A delay line 340 inserts unstable settling delay into the clock route. At the start point of the delay line 340, some unstable state occurs in a low speed clock domain and a high speed clock domain and they are settled through the whole length of the delay line 340 (through one, two or three cycles of a low speed clock). A reproduced clock signal SLOW-R appears after a period when the rise edge is shorter (but variable) from the rise edge of a clock signal SLOW. Since the pulse width of a reproduced clock signal SLOE-R is short, the fall edge of the reproduced clock signal SLOE-R is generated considerably earlier than the clock signal SLOW. Thus, the clock domains of the clock signals SLOW and FAST is synchronized without waiting time.

Title: Continuous type sintering furnace
Inventor: YUZAWA YUKIO
IPC: B22F3/10
Filed: 1980-08-28
Abstract: PURPOSE: To quickly remove lubricant adhered to the surface of an object treated by a simplified system in which a space is provided above a pathway leading to a sintering zone, high-temperature waste gas is sent to the space where its pressure is equalized, and then the waste gas of equalized pressure is jetted onto an object treated.  
     CONSTITUTION: A space 8 surrounded by a fire-proof wall 7 is provided above the pathway 5 of a dewaxing zone, and a mixture of fuel gas and air is burned by burners 10 provided on both sides of the space 8. Since the space 8 and the pathway 5 are partitioned by a partition wall 11, flame is stabilized and good quality non- oxidative gas is formed. The combustion waste gas become of high and equalized pressure in the space 8 and then is vertically jetted toward the pathway 5 for treated object through all vent holes provided in the partition wall 11. Thus, the treated object being moved is exposed to the jet stream of the high-temperature waste gas and heated uniformly and quickly. Since the gas is reductive, lubricant adhered to the surface of the treated object is quickly removed.

Abstract: PURPOSE:To secure the thickness of an insulating layer endurable against damages due to junctions, by providing a junction pad after providing an insulating film on an Si substrate thinner than a field oxide film and after laminating a conductive layer and an insulating layer. CONSTITUTION:The poly Si conductive layer 13 and an SiO2 layer 14 are superposed on a gate oxide film 12 on the P type Si substrate 11, and the junction pad 15 is formed by opening a window on a protecting film 18. Besides, the conductive layer 13 is connected to the N<+> layer 16 formed at the position other than that of the pad 15. In this constitution, the film thickness sufficiently endurable against damages due to the junction can be secured on the substrate under the junction pad for the take-out of an external electrode. Accordingly, the decrease of the yield and reliability at assembly can be prevented, enabling it to cope with the thinning of the layer of the insulating layer which is apt to happen at the time of making the product microminiaturized.

IPC: H03H17/06
Filed: 1986-05-23
Abstract: PURPOSE:To simplify hardware and reduce the power consumption by providing an FIR filter whose pass characteristic is symmetrical with respect to 1/2 of the sampling frequency of an original digital signal and selectively taking out the output of this FIR filter and the output obtained by multiplying the input signal by a fixed coefficient. CONSTITUTION:As shown by broken lines, multipliers 52, 54-510 are so removed that the pass band and the stop band have a 1/2 frequency FS/4 of a sampling frequency FS/2 of the original digital signal, that is, the filter characteristic symmetrical with respect to a cut-off frequency FC is obtained. Consequently, a signal delay circuit having a delay time 2/FS exists between multipliers equiva lently. Then, this FIR filter 2 is operated by a clock signal having the frequency FS/2, namely, the same sampling frequency as the original digital signal. Thus, the number of taps of the filter is reduced to a half and parts operated by high-frequency clocks are removed.
