Title: Optical disk and recording method thereof
Inventor: YAMAZAKI CHOJI
IPC: G11B7/0045
Filed: 1991-08-30
Abstract: PURPOSE:To increase recording capacity per face by dividing the recording zone of an optical disk into two to ten recording zones for each recording track having inverse for a specific pitch and recording density. CONSTITUTION:The track pitch of the optical disk 10 is made narrower than 1.6mum, and the inverse of the line recording density of the recording track in the peripheral direction is specified at 1.0-0.6mum per a bit. And, the zone of the optical disk 10 is divided into plural tracks to provide recording zones, and the dividing number is made two to ten. Here, the total recording bits in the radius R of the optical disk 10 is indicated by the product of total recording bits per a sector multiplied by the number of sectors, and the inverse of the recording density in one track is indicated as a length required for one bit. Thus, the recording density of the track T2 in the outermost radius R2 against the track T1 of the innermost radius R1 in the recording zones of the optical disk 10 is made the one required by dividing the optical disk 10. Consequently, the recording capacity per face is easily increased without reducing the access speed.

Inventor: TAKEUCHI OSAMU
IPC: C21D1/52
Filed: 1993-09-30
Abstract: PURPOSE:To prevent the development of oxide scale at the time of heating a steel material. CONSTITUTION:On the downstream side in the line direction in a furnace, an incomplete combustion is executed at a low air ratio so as to execute non- oxidizing or reducing heating to the steel material 5. At that time, sets of a pair of direct firing type burners 7, 8 on the downstream side in the line direction in the furnace are alternately burnt, and the high temp. combustion gas 9 from air ports 7a, 8a for combustion in the other burners 7, 8 is introduced into the one side regenerator 18 while the one side burners 7, 8 are used to recover the heat. Successively, the air 14 for combustion is passed through the regenerated regenerator 18 by changing over the line and heated and supplied to the other side burners 7, 8 to continue the incomplete combustion at the low air ratio. Further, the combustion gas 9 containing unburned combustibles recovered with the heat in the regenerator 18 is supplied to direct heating or radiant tube type burner 6 as fuel gas and the complete combustion is executed on the upstream side where the temp. of the steel material is low.

Title: Hydraulic control device for belt type continuously variable transmission with direct coupling mechanism
Inventor: AIKAWA HIROSHI
IPC: B60W10/101
Filed: 1986-10-15
Abstract: PURPOSE:To reduce an oil pump loss, by providing a selector valve in a pulley control oil line and opening an oil path by the selector valve in the time of continuously variable driving while regulating a line pressure by a pulley controlling solenoid valve even in the time of directly coupled driving. CONSTITUTION:A pulley controlling solenoid valve 171, start controlling solenoid valve 172, direct coupling controlling solenoid valve 173 and a selector valve 180 are provided in a hydraulic control device for controlling a driven side pulley 42, starting clutch 60 and a direct coupling clutch 15. The selector valve 180 opens an oil path, when a transmission is continuously variably driven, and closes the oil path when the transmission is driven being directly coupled, while a line pressure is regulated by the pulley controlling solenoid valve 171 not only in the time of continuously variable driving but also in the time of directly coupled driving. In this way, the continuously variable transmission provides no possibility of changing its speed change ratio even if the pulley controlling solenoid valve 171 continues the action in the time of directly coupled driving, while the transmission, in which the line pressure can be regulated to the value of minimum required limit, enables an oil pump loss to be decreased.

Abstract: PROBLEM TO BE SOLVED: To easily remove and recover metals from polluted soil by arranging electrodes in the metal-containing environments, moving metals toward the electrode sides by generating an electric field, adsorbing the metals with an adsorbent, and taking the metals out of the electrodes. SOLUTION: A pair of spherical electric bulbs 3a, 3b and a d.c. electric power source 5 are so connected as to set the electrode 3a as an anode. The surfaces of the respective electrodes 3a, 3b are covered with a protective film made of unwoven cloth and surrounded with hollow spherical filters 9a, 9b made of a semi-transparent film of a porous material. Filling chambers 11a, 11b are formed between the filters 9a, 9b and the electrodes 3a, 3b and filled respectively with anion-exchange resin 13a and cation-exchange resin 13b. Both electrodes 3a, 3b are arranged in polluted environments and voltage is applied to the electrodes and an electric field is generated between the electrodes 3a, 3b. Consequently, metals are ionized and move toward the electrodes 3a, 3b and captured in the anionexchange resin 13a and the cation-exchange resin 13b.  Together with the respective ion-exchange resin 13a, 13b, metals are recovered by operating vacuum pumps 19a, 19b.

Title: Talking equipment for elevator
Inventor: SONOMOTO KIYOSHI
IPC: H04M9/00
Filed: 1989-09-22
Abstract: PURPOSE:To reduce quantity of recording medium, to decrease replacement of recording medium and to reduce the retrieval time of required talking content by recording only required conversation among coversations communicated between a handset of a cage of an elevator and an operator reply device of a monitor sensor. CONSTITUTION:Since a handset 1 in a cage and an operator reply device 21 of a monitor sensor C are interconnected via a telephone line D at check, the check personnel and the operator of the monitor center C communicate with each other to check the elevator. However, since the recording device 22 and the operator reply device 21 are interrupted at a check conducted periodically, the conversion at check is not recorded on the recorder 22. Thus, unnecessary conversation is not recorded, the quantity of the recording medium is reduced, number of times of replacement of the recording medium is reduced and the time required for the retrieval of the required speech content is reduced.

Filed: 1989-09-21
Abstract: PURPOSE:To suppress the deterioration of catalyst and increase the production of styrene by carrying out dehydrogenation reaction of ethylbenzene in the presence of steam and a catalyst containing K component while supplying CO2 and/or CO to the reaction system. CONSTITUTION:Styrene is produced by the dehydrogenation reaction of ethylbenzene in the presence of steam and a catalyst containing K component. The reaction is carried out under an inlet condition of 550-650 deg.C and 0.45-0.85atm while supplying CO2 and/or CO to the reaction system at a rate of 1.0X10<-3> to 2.0X10<-2>mol per 1mol of ethylbenzene. The CO2 and/or CO are supplied preferably to the inlet part of the reactor because a very small amount of CO2 or CO is produced by side-reaction and the produced CO2, etc., suppress the deterioration of the catalyst at the downstream part of the reactor. The supply of CO2 and/or CO prevents the dissipation of K in the catalyst (e.g. Fe-K catalyst or Fe-Mg-K catalyst).

SOLUTION: An input register part 2 divides inputted picture space data or transformation coefficient data into half data of the required number of data as the time- divided array of 1st and 2nd data. In the case of DCT, the divided data are respectively processed by a butterfly operation part 3 and a bit division part 5, the processed 1st and 2nd data are individually multiplied by respective transformation coefficients by a multiplication port 6, the accumulative addition of the 1st and 2nd data is executed by an accumulative addition part 7 and transformation coefficient data are obtained by an output register part 10.  In the case of IDCT, the divided data are respectively processed by the bit division part 5, the 1st and 2nd data are individually multiplied by respective inverted transformation coefficients by the multiplication part 6, the accumulative addition of the lst and 2nd data is executed by the accumulative addition part 7, the accumulative addition result is processed by a butterfly operation part 8, and IPCT data are obtained from an output register part 10. Since the accumulative addition part 7 requires only data corresponding to the number of 1st and 2nd data, the number of data can be reduced to a half.
