Inventor: HASEGAWA KATSUMI
IPC: B29C70/06
Filed: 1987-07-29
Abstract: PURPOSE:To improve uniform impregnating capacity of a sheet-like matter with a solution and to prevent generation of the surplus impregnating solution, by a method wherein the sheet-like matter during running is impregnated up to the middle of its thickness in the direction of the thickness with the solution to be pressed in while the sheet-like matter is being brought into contact with an opening end of a box-like body and then the same is impregnated with the solution by a pair of nip rolls. CONSTITUTION:A box-like body 4 of a pressing-in device 2 possesses an opening part 8 on a sheet side, and a pressing-in chamber 10 in an airtight state is formed by bringing a fringe face 9 of the said box-like body 4 into contact with a sheet 1. When a solution is pressed in the pressing-in chamber 10 through an introduction port 11 of the pressing-in device 2, the said solution is infiltrated into the sheet 1 through a small hole 15 of a pressure control plate 12 after the inside of the pressing-in chamber 10 has been filled with the said solution. Now, when the optimum infiltration depth l1 necessary for making the sheet 1 into a state where it is infiltrated evenly in the direction of a sheet thickness finally by one time-pass through the pressing-in device 2 and a nip device 5 without lowering a fabric breathing rate of the sheet 1 is shown by an infiltration ratio l1/t1 to a sheet thickness t1 prior to its treatment, the said infiltration ratio falling within range of 70-82% of the thickness t1 is preferable. When a preferred degree of nip of the nip device is shown by a pressurizing ratio t2/t1 by making use of a gap 2 between rolls, the said pressurizing ratio falls within a range of 0.75-1.15 times as thick as the infiltration ratio l1/t1.

Title: Piezoelectric loudspeaker
Inventor: TAKAYA TADASHI
IPC: H04R17/00
Filed: 1988-07-29
Abstract: PURPOSE:To prevent the lowering of sound pressure between a first-order resonance and a second-order resonance by fitting not only a piezoelectric sounding body to generate the first resonance and the second resonance but also another piezoelectric sounding body having the resonance frequency between the first-order resonance and the second-order resonance to a diaphragm and oscillating the diaphragm. CONSTITUTION:Piezoelectric sounding bodies 4 having the same characteristic with each other are fitted to five parts of a rectangular diaphragm 3, which are the center and near the four corners of the diaphragm 3, two types of piezoelectric sounding bodies 5 and 6 respectively having different characteristics from that of the piezoelectric sounding bodies 4 are fitted to the diaphragm 3, and all the sounding bodies are connected in parallel. Since the first resonance mode of the diaphragm 3 appears in its longitudinal direction and in its cross direction, and respective oscillations have nodes I and J, each of which generates partitioned oscillations at its both sides, between centers E and F and edges G and H, the piezoelectric sounding bodies 4 near the four corners are fitted to intersections where the segments (i) of the nodes I and the segments (j) of the nodes J intersect and arranged so that the partitioned oscillations are never generated actually. For the piezoelectric sounding bodies 5 and 6, the sounding bodies having the resonance frequencies between the first resonance frequency and the second resonance frequency generated in the diaphragm 3 with the respective piezoelectric sounding bodies 4 are used, and as the result, the lowering of the sound pressure between the first resonance and the second resonance can be eliminated, and a low sound can be sounded.

Title: Errorless exchange technology in ring network
Inventor: CHAUDHURI SID
IPC: H04J3/06
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To conduct errorless exchange effectively by using other delay to attain phase arrangement of signals and adjusting the delay to eliminate accumulated delay that otherwise deteriorates quality of data transmission. SOLUTION: Signals A-Q are given to a protective channel 9 of fibers 20, 20A in a transmitter side node A to shift a delay from a node C to a node Q. Two signals in a terminal node Q are arranged by adding a proper delay to an elastic store ES 6 storing signals connecting to the channel 9. Then a delay in the intermediate node C is shifted to the terminal node Q through errorless exchange. The delay in an elastic store ES5 is eliminated till a succeeding fault takes place in any ring on the signal path. The errorless exchange is conducted effectively by eliminating the accumulated delay being a cause to deterioration in the quality of data transmission through the shift of the delay in the terminal node.

Title: Semiconductor device and manufacture thereof
Inventor: HORIUCHI KATSUTADA
IPC: H01L21/331
Filed: 1984-09-14
Abstract: PURPOSE:To increase the speed of operation of an element remarkably by forming en electrode by a metallic silicide, to which an impurity constituting the same conduction type as the conduction type of a connected region is added, and shaping a maximum impurity-concentration region in the region in relationship of self-alignment with a metallic silicide film. CONSTITUTION:The speeding-up of an I<2>L with four collectors largely depends upon a novel effect by the formation of extremely shallow P<+> type regions 291-294 in high concentration constituted in relationship of self-alignment with a metallic-silicide extracting electrode 28 in addition to each effect of the reduction of capacitance between a base and a collector by an insulating film 20 and the reduction of electrode-sheet resistance by the metallic-silicide extracting electrode 28. That is, the base-emitter resistance rbb' of a vertical type NPN transistor is reduced to 20OMEGA, and minimized to approximately 1/10 of conventional devices. It will be because contact resistance among the base extracting electrode 28 and graft bases 293, 294 is made largely lower than conventional devices by the effect of the increase of the concentration of the graft bases 293 and 294.

Title: Erasable read-only storage element
Inventor: FURUKAWA YUUICHI
IPC: H01L21/8246
Filed: 1983-10-13
Abstract: PURPOSE:To erase write data efficiently by providing an additional memory cell array which requires the significant difference irradiation amount of ultraviolet rays more than the minimum irradiation amount of a standard memory cell array because of write data erasure. CONSTITUTION:The additional memory cell array 7 is increased locally in thickness by, for example, 30%. Cells in a memory cell array 1 requires a drain- source voltage VPP, e.g. 21 volts (V) and a control gate-source voltage VCC, e.g. 5V for writing, but the additional memory cell array 7 requires the VPP and a control-gate high operating voltage VHH, e.g. 10V, and the minimum ultraviolet- ray irradiation amount required for erasure increases from conventional 7WS/ cm<2> to 10WS/cm<2>. When an additional control circuit 8 is enabled with the VHH, an incorporated operational amplifier 80 compares the VHH with the VCC to send out an inhibition signal to a row decoder 4a. Consequently, close erasure control corresponding to the erasure characteristics of a PR-OM piece is performed.

Title: Liquid crystal display device
Inventor: IKUMA KATSUMI
IPC: G09F9/35
Filed: 1985-08-30
Abstract: PURPOSE:To increase the contrast between a display part and a display screen by increasing the transmissivity of a front glass substrate selectively by the wavelength of a color to be displayed, and transmitting color light from an illumination light source through the front glass substrate and displaying it on the surface. CONSTITUTION:When the illumination light source is turned on, its illumination light illuminates a rear polarizing plate 24 through a color filter 25 and is deflected into, for example, a lateral wave, which is inputted to liquid crystal 13. Then, the wave is passed through the liquid crystal 13 which is impressed with no voltage and then the wave is twisted by 90 deg. and converted into a longitudinal wave, which is not led out of a front polarizing plate 23 which does not coincide with the polarization direction. When a voltage is impressed to electrodes 18 and 19, the lateral wave incident on the liquid crystal 13 is unchanged in direction even after passing through the liquid crystal 13, so the wave is led out of the front polarizing plate 23. The transmissivity of the front glass substrate 14 is set low, so the display screen 9 becomes dark. At this time, the color wavelength transmissivity of the front glass substrate 14 is set high selectively, so a display pattern is displayed sharply.
