Title: Production of flame-retardant paper for paper honeycomb core
Inventor: NOMURA TAKUYA
IPC: D21H17/49
Filed: 1994-07-18
Abstract: PURPOSE:To provide a process for the production of a flame-retardant paper for paper honeycomb core, composed of an inorganic paper containing flame- retardant inorganic powder and having excellent flame-retardancy and compressive strength. CONSTITUTION:An inorganic paper containing 65-80wt.% of inorganic powder is impregnated with (1) 2-10wt.% (based on the bone-dry weight of the inorganic paper in terms of solid weight) of a synthetic resin having methylol group and (2) 100-200wt.% (based on the solid weight of the synthetic resin) of a guanidine-based flame-retardant produced by mixing sulfamic acid or phosphoric acid with cyanoguanidine and formaldehyde at molar ratios of 1:(1-1.5):(0.2-3). The impregnated inorganic paper is dried by heating to effect the crosslinking reaction of the methylol group in the synthetic resin and the crosslinking reaction of the synthetic resin with the guanidine-based flame-retardant.

Title: Digital signal processor
Inventor: HIROTA YUTAKA
IPC: H03M1/12
Filed: 1979-12-18
Abstract: PURPOSE:To prevent interference due to folded noise, by making higher the sampling frequency used for decoding than that at encoding. CONSTITUTION:Taking the sampling frequency as fS, the input analog signal is limited to the spectrum fS/2 or lower at the low-pass filter 1. When the input signal level is small, since higher frequency components are produced at encoding, the sampling frequency at decoding is taken higher than that at analog-digital conversion, e.g., 2 fS. Thus, no folded noise is produced between the spectrum 24 for encoded signal and the spectrum 25 for playback signal.

Title: Tape remaining time display device
Inventor: KABURAGI HIDETAKA
IPC: G11B27/17
Filed: 1991-06-10
Abstract: PURPOSE:To increase the display precision of remaining time by making the increase of physical ROM capacity a reference table and interpolating with a prescribed expression. CONSTITUTION:When the rotational cycle of a reel is T, the line velocity of a tape is V, the area of a reel hub is S, the thickness of a tape to use is B and 1/2pi=A are defined, tape remaining time Rem is usually calculated with the expression I by detecting a reel pulse. In such a manner, since a cutting-off error is generated by the physical limitation of a ROM table, the remaining time with high precision is incapable of finding. Then, a differential coefficient Rem', the expression II obtained by differentiating the expression I is multiplied to the omitting difference DELTATsec omitted, the multiplied expression is added to the expression I as an interpolating data, and the expression III interpolating the gap of quantization is defined, the calculating precision of the remaining time is improved remarkably while holding the ROM table to a small size. The remaining time is calculated by the expression III since the cycle Tsec of two revolutions of the feeding reel 1a is detected by a reel pulse detector 3. The reel pulse is inputted to a micro-processor 5 through a waveform forming shaping circuit 4 and the cycle T is represented with hexadecimal number of maximum 12-bit length.

IPC: H01G4/12
Filed: 1988-07-01
Abstract: PURPOSE:To shorten the shifting distance of electrons in inner electrode within a high-frequency region by a method wherein the electrodes to be divided are divided in multiple numbers in the long direction of dielectric layers. CONSTITUTION:For example, two electrodes 1b to be divided in rectangular shape and in the same dimensions of l, w are formed in the positions slipped from those of other split electrodes 1a, 1b i.e., with both ends thereof in the long direction opposite to adjacent two electrodes 1a to be divided. Furthermore, for example, the other three split electrode 1c are formed on the same positions as those of the split electrodes 1a on the boundary held by dielectric layers 2c, 2d with the ends of the electrodes 1c at both ends coincided with the ends in the long direction of the dielectric layers 2a, etc., to be connected to extraction electrodes 3. Thus, respective split electrodes 1a-1c are arranged in zigzag shape partly opposite to one another holding the dielectric layers 2b, 2c. Consequently, the shifting distance of electrons in every one of the respective split electrodes 1a-1c is shortened, thereby shortening the shifting distance of electrons of a multitude of split electrodes assembled as a whole.

Abstract: PURPOSE:To simplify a processing process, and to shorten a processing time even when the bit array of data stored in a storage device is different from the bit array of the processing data of a compressing and extending device by providing first and second converting means at a converting means. CONSTITUTION:In an information processor 100, a converting means 400 converts the data of a first bit array extracted from a storage device 200 by a compressing and extending device 300 into a second bit array, and transmits the data to the device 300. Also, the converting means 400 converts the compressed or extended data of the second bit array outputted by the device 300 into the first bit array, and stores the data in the device 200. Thus, the converting means 400 operates a processing which is independent of a program processing. Therefore, even when the bit array of the data stored in the device 200 is different from the bit array of the processing data of the device 300, the bit array of the data extracted from the device 200 by the device 300 are converted by the means 400, and transmitted to the device 300. Also, the bit array of the output data from the device 300 is similarly converted, and stored in the device 200. Thus, the processing can be simplified, and the processing time can be shortened.

Title: Tape recorder with radio
Inventor: NOGUCHI NAOTO
IPC: H04B1/20
Filed: 1981-10-16
Abstract: PURPOSE:To prevent unnecessary consumption of batteries by inhibiting a current from flowing to a tape driving motor once a radio/tape changeover switch  is placed at a radio-side terminal even if the playback switch of a tape recorder is turned on. CONSTITUTION:When interlocking ratio/tape changeover switches 10a and 10b are placed at radio-side terminals R, feeding to a motor 9 is cut off by the switch 10b and the motor 9 is powered down completely. In this state, when a playback and a recording button are both pressed, recording switches 12a and 12b are both turned on, so the output of a low frequency amplifier 6 is applied to a magnetic head 3 through the recording switch 12a and a recording amplifier 5 and at the same time, electric power from a power source +B is applied to the tape driving motor 9 through the recording switch 12b. Consequently, even if the playback button 11 is pressed during radio reception, no current flows to the motor 9 and unnecessary consumption of batteries is prevented.

Abstract: PURPOSE:To surely obtain a TiN-Al2O3 sintered compact excellent in physical strength at a low cost of starting material without requiring a troublesome producing process by firing a compact of a mixture having a specified ratio of powdery TiO2 to powdery AlN powder in an inert atmosphere. CONSTITUTION:A starting material mixture having 2/(3-1) weight ratio of powdery TiO2 to powdery AlN is compacted into a prescribed shape and the resulting compact is fired in an inert atmosphere to obtain the objective TiN-Al2 O3 sintered compact. The compact is fired in a firing furnace filled with an inert gas such as nitrogen, argon, neon or helium. This furnace is preferably filled with nitrogen because nitrogen in the atmosphere takes part in the nitriding reaction of TiO2 and the nitriding reaction is accelerated as a whole. Nitrogen is also advantageous cost-wise.
