Title: Picture signal coding system
Inventor: YOSHIDA SHIGERU
IPC: H04N19/50
Filed: 1984-09-06
Abstract: PURPOSE:To obtain a good coding efficiency and a large compressed ratio by blocking and coding in a lump picture elements only of a high forecasting hitting ratio with a mode signal and variable-length-coding picture elements of a low forecasting hitting ratio as they are. CONSTITUTION:A picture signal is 16 hexadecimal values of 0-15 (4 bits/picture element). Here, l is the number of a picture element and a picture signal for (l+2) picture element is accumulated at a shift register 20. Out of these, refer ence picture elements for forecasting (a), (b) and (c) are inputted in a forecasting device 21. The forecasting device 21 outputs a forecasting signal. A forecasting error D is obtained from this and a coding picture element signal X of the shift register by a subtracter 22. A code is allotted to respective forecasting errors as a compressed code. In this code, a short code is allotted for forecasting errors with high appearing frequency, and efficient compressed coding is real ized. After a variable length coding of a block, in which a GOOD mode continues, is completed, continuously after this, a forecasting error D of a pic ture element of the BAD mode is variable-length-coded.

Title: Sound reproducing device
Inventor: SAWAI TOSHIHITO
IPC: G11B20/10
Filed: 1990-07-18
Abstract: PURPOSE:To reduce the effect of residual noise and distortion at a low level signal and to improve S/N by adopting a cut-off frequency variable type HPF for the HPF connecting to an LPF and changing the cut-off frequency proportional to an input level of a D/A converter. CONSTITUTION:An LPF 7 and an HPF 8 eliminate an undesired harmonic wave component from an output of a D/A converter 6, and a cut-off frequency variable type filter is adopted for the HPF 8. The cut-off frequency of a frequency characteristic (a) of the HPF 8 is least as 20Hz and the characteristic is used when an input to the D/A converter 6 is close to a maximum level. The cut-off frequency is sequentially increased in other characteristics b, c, d. A control microcomputer 11 monitors an output level of a digital signal processor DSP 5 and selects the characteristic from the characteristic (a) toward the characteristic (d) as the level is decreased. The characteristic (d) is used when the output level of the DSP 5 is least and then a prescribed level of the output of the D/A converter 6 is cut off and the effect of distortion and noise is reduced. Similarly, the characteristics (b), (c) are used at an intermediate level with respect to the characteristics a, d.

Title: Controller for mechanical supercharger
Inventor: FUKUSHIMA KOJI
IPC: F02B33/00
Filed: 1985-08-29
Abstract: PURPOSE:To keep a low rate of fuel consumption as well as to prevent black smoke from occurring at the time of high load, by regulating a degree of opening in a control valve in a bypass passage according to oxygen content when a mechanical supercharger operates. CONSTITUTION:A control valve 34 is in a state of full-open at a low load range where a supercharger is nonoperational.

Title: Terminal remote maintenance system for isdn communication network
Inventor: YAGI TSUKASA
IPC: H04L69/40
Filed: 1990-07-17
Abstract: PURPOSE:To eliminate the need for the installation of a specific MODEM for remote maintenance and a control line by performing the communication of a data for maintenance with the use of the packet communication of the signal channel of an ISDN communication network 4. CONSTITUTION:A packet P3 can be returned from a terminal equipment 2 to a terminal 1 for maintenance since the transmission to the terminal equipment 2 is performed by transmitting a packet P1 from a terminal 1 for maintenance even when terminal equipments 2 and 3 perform not only the communication by information channel but also packet communication by the signal channel and the transmission of a packet P2 from the terminal equipment 3. Therefore, when a function identifying a command from the terminal 1 for maintenance to respond it is imparted with the terminal equipment 2, remote maintenance can be realized. Thus, it is realized by imparting two incoming numbers for terminal identification to the terminal equipment for the object of the remote maintenance.

Title: Thin film forming method
Inventor: SUGIYAMA NAOHARU
IPC: H01L21/316
Filed: 1993-07-30
Abstract: PURPOSE:To form an n type semiconductor thin film containing impurities in high concentration by a method wherein the substrate temperature in a reaction chamber, the hydride gas filled in the vessel and the partial pressure thereof are specified so as to irradiate a substrate with hydrogen ions. CONSTITUTION:An ultiahigh vacuum vessel 1 is by a turbo molecular pump 4. Next, at least one kind of hydride gas containing IV group element at the partial pressure not exceeding 1X10<-1>Pa e.g. disilane gas and another hydride gas containing V group element e.g. arsine gas are led into this vacuum vessel 1. Leaving such a state intact, a substrate 3 is heated at the temperature not exceeding 750 deg.C e.g. 650 deg.C by a heater 2 arranged in the vacuum vessel 1. Next, the substrate 3 is irradiated with hydrogen ions to be decomposed into respective gasses for the formation of semiconductor thin film. At this time, the hydrogen ions are fed from an ion chamber 7 coupled with the reaction vessel 1 by working exhaust in vacuum mode. Through these procedures, a low resistance silicon layer can be formed without decelerating the growing rate even if meeting the requirements for adding an n type dopant in high concentration.

Abstract: PROBLEM TO BE SOLVED: To highly accurately perform positioning by coating a photosensitive material on a glass substrate on which an electrode pattern is formed and positioning a photomask and the glass substrate with the photosensitive material on a positioning mark. SOLUTION: Positioning is performed under oblique illumination using a light source with wavelength 500-800 nm and preferably, the light source includes one or a plurality of light emitting diodes.

Title: Membrane for separation
Inventor: KUSUDO OSAMU
IPC: B01D71/30
Filed: 1980-12-29
Abstract: PURPOSE: To obtain a membrane for separation having superior acid resistance and oxidation resistance by sticking polyvinyl chloride (PVC) on the inside and outside surfaces of the membrane with specific micropore sizes and the inside surfaces of the pores of the membrane.  
     CONSTITUTION: In a membrane having fine structure with 0.01W1μ average pore sizes, PVC is stuck approximately uniformly on the inside and outside surfaces of the membrane, and the inside surfaces of the pores of the membrane. The concn. of this sticking is not required to be the same in all the places; for example, the concn. of the sticking higher on the inside and outside surfaces of the membrane than on the inside surfaces of the pores gives equally good results. The preferable concn. of the sticking is to the extent of not changing the average pore sizes of the membrane largely and of not degrading permeation performance, etc. and it is about 2.5W40wt% basing on the weight of the membrane backing material. The PVC is stuck by the method of immersing the membrane backing material in a soln. prepd, by dissolving PVC in a solvent to allow the soln to be impregnated thoroughly with said material and removing the liquid in a manner as to avoid drying the surfaces at ordinary temp. or below the boiling point of the solvent and further drying the same. The liquid removal is accomplished by leaving the membrane under gravity in a tightly sealed housing or exerting centrifugal force thereto. The film backing material is a backing material having low acid resistance and oxidation resistance such as polyvinyl alcohol (PVA) polymer or the like.
