Title: Recording and decoding method for digital information
Inventor: IWAI TOSHIYUKI
IPC: G06K1/12
Filed: 1995-03-10
Abstract: PURPOSE: To provide a digital information recording method capable of distributing marks with the same value so as not to continue both in the row and column directions and easily performing recording without reducing information quantity when digital information is recorded on an information recording area provided in a recording surface in square unit in accordance with a bit. CONSTITUTION: A small block with specific shape to fill the information recording area 23 without generating a gap is set. Patterns for modulation formed by attaching the marks with different values on the squares in the row and column directions relating to at least one row and one column are employed in the small block. A primary pattern in accordance with recording information is taken out in unit of small block, and exclusive OR is calculated by making a taken out pattern cope with the pattern for modulation at every square in one to one. A secondary pattern formed by arranging a pattern in unit of small block consisting of the mark representing the value of exclusive OR is expressed on the information recording area 23.

IPC: B01D53/34
Filed: 1981-04-06
Abstract: PURPOSE: To remove the impurities from a gas composed mainly of CO and H 2  and containing H 2 S, CS 2  and COS as impurities, easily and effectively, by passing the gas through the packed layer of CaO having specific characteristics.  
     CONSTITUTION: A gas composed mainly of CO or CO and H 2 , containing H 2 S, CS 2  and COS as impurities and free from SOX is passed through the packed layer of CaO having a specific surface area of ≥3m 2 /g (preferably prepared by  calcining CaCO 3  in an inert gas atmosphere at 700W1,000°C) to effect the desulfurization of the gas. The temperature of the packed layer is preferably maintained at 300W1,000°C.  
     EFFECT: Since the desulfurization rate per unit CaO is extremely high, the packed layer has a long life as a desulfurization agent.

CONSTITUTION:An endless belt provided with a solid-state dielectric layer 22 on a conductive base body is set to rollers 20, 21 with the dielectric layer 22 outside and turned in the direction as indicated with an arrow. First of all, the surface of the dielectric layer 22 is destaticized to about ''0''V by an AC electrifier 23. Subsequently, an electric signal corresponding to a display picture is sent to a digital electrifier 24, a digital charge pattern of a picture is formed on a photosensitive drum 22, and this charge pattern is converted to a developed image by a developing device 27. This solid-state dielectric or its surface is made white in order to maximize the contrast of a toner image and the solid- state dielectric being a background. In this way, an electrophotograpy display of full colors or multicolors is obtained.

Title: Elevator device
Inventor: MOURI MASAHIRO
IPC: B66B7/08
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To improve load detecting performance, and reduce cost, and facilitate an adjustment and the replacement by incorporating load detecting devices into shafts or its bearing parts of respective sheaves of roping in an elevator to raise-lower a car by suspending the car and a balance weight by the roping having the specific ratio. SOLUTION: In an elevator of 2:1 roping by which a sheave 8 for a car is installed in an upper part of a car frame B, a pin type load cell 9 is used as a main shaft of a sash pulley (a sheave for a car) 8, and is constituted so as to detect a load in a main shaft part. According to this, since the number of load detect devices can be reduced, an adjustment and the replacement can be easily performed, and cost can be reduced. Since there is no need to detect a load through an elastic body between a floor 1 and a floor receiving frame 2, the possibility of deteriorating measuring accuracy is precluded. A weight change in a tail cord 5 and a compensator 6 or the like by a car position can also be detected, and smooth comfortableness to ride in can be obtained by reflecting its variation on torque control.

Title: Oscillator
Inventor: MURAKAMI OONORI
IPC: H03B5/12
Filed: 1980-04-18
Abstract: PURPOSE:To attain the location with small area even with the use of resistors having 5% the standard deviation, by inserting the element for extending base potential difference between the emitter and the constant current source of an oscillator transistor or between the base and the base potential setting means. CONSTITUTION:The emitter of differential transistors 1, 2 is connected via diodes 12, 13. The gain G' of the differential amplifier is expressed as equation (I). Since G' is at 6dB for VB2-VB1 when G' is at >=0 dB, VB2-VV1=273mv by obtaining VB2-VB1 from equation II when IE1=0.0052IE and the range of possible oscillation can be extended by about 120mv than conventional circuits. Experimentally, the range can be extended to + or -200mv. Thus, the range of possible oscillation is close to the deviation of + or -212mv by 5% resistors, resulting that most of assemblies are nondefective goods. Further, the extension of the dynamic range can initiate the oscillation stably even with the deviation of the set bias voltage more or less.

Abstract: PURPOSE: To prevent the generation of deformations by installing a fiber sheet and a breathable sheet member inside a core material of a composite material under sandwich structure or a bordering area between the core material and a front surface material or between the core material and a rear surface material. CONSTITUTION: A core material 3 made of a synthetic resin foam, such as phenol foam is filled up between a surface material 1 and a rear surface material 2, which are made of a metal sheet, thereby forming a composite panel A.
