Title: Amplifying circuit
Inventor: KATO MASAHIRO
IPC: H03F1/22
Filed: 1989-12-15
Abstract: PURPOSE:To form an amplifying circuit which has a large voltage gain by constituting the amplifying circuit of a current injection means including a 3rd FET which controls the injection amount of a current to an amplification means according to the output of the amplification means. CONSTITUTION:The amplifying circuit consists of the amplification means consisting of FETs Q1-Q3 and the current injection means consisting of an FET Q4 and a resistance R. A feedback loop regarding an output voltage is constituted through the current path of the current injection means which is controlled by the variation of the output voltage. Further, this feedback operates as positive feedback under proper conditions determined by transfer conductance and drain conductance at the operation bias point of the FETs constituting the circuit and the amplitude of an output signal opposite in phase to an input signal can be made extremely large. Consequently, the voltage gain at the time of inputting a small signal can be made larger and the amplifying circuit which has the large voltage gain is obtained.

Title: Information medium, information reproducing method and information reproducing device
Inventor: KIKUKAWA TAKASHI
IPC: G11B11/12
Filed: 1999-11-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute high-density information recording and to easily execute reproduction of high-density recording information with simple means by reading out the difference in a crystalline state or crystalline phase or component material as a difference in surface potential or surface charge density and executing the reading out of the recording information of a medium. SOLUTION: A phase transition type recording disk (CD-RW disk) having recording layer of an In-Ag-Te-Sb-base composition is subjected to signal recording by a CD-RW drive assembly. Next, the dielectric layer, reflection layer and resin protective layer existing on the recording layer are peeled to expose the recording layer surface and the surface potential distribution patterns are made into images, by which the images shown in Fig. are obtained. The regions where lightness high are the regions where the surface potential is high and approximately completely coincide with the amorphous recording marks. For example, the surface potential difference between the amorphous recording marks and the other regions is 50 mV and the electrostatic capacity difference is 3×1010 μF.  As a result, the high-density information recording and the reproducing of the high-density recording information are made possible.

Title: Recording and reproducing device
Inventor: KITANO GINZO
IPC: H04N7/169
Filed: 1994-12-27
Abstract: PURPOSE: To satisfactorily keep the secrecy by inputting a registered password number, recording the video signals to be registered after scrambling them, and descrambling the video signals recorded with scrambling after the input of the same password number. CONSTITUTION: A password number register mode is designated at an operation part 32, and a password number is inputted through a ten-key pad. Then the password number is registered in a register memory 34 as the password number data by means of a register key. As the memory 34 is a nonvolatile memory, the password number data are never erased even after the power supply of a record/reproduction device is switched off. When the stored password number data are reproduced, a scramble reproduction mode is commanded at the part 32 and the password number registered previously is inputted through the ten- key pad of the part 32. A controller 31 decides whether the inputted password number is coincident with the password number that is registered in the memory 34. Then the controller 31 shows its decision result at a display part 33.  If the coincidence is secured between both password numbers, a start key is pushed at the part 32 and the record/reproduction device is set in a scramble reproduction mode.

Title: Carbon dioxide adsorbing element
Inventor: OOHASHI KUNIMICHI
IPC: B01D53/04
Filed: 1991-11-13
Abstract: PURPOSE:To dispense with a large-scale ventilation device and to efficiently utilize the adsorbing capacity of an adsorbent by forming a large number of through holes to a peripheral wall composed of a base material having a carbon dioxide adsorbent bonded thereto to use them as passages of carbon dioxide- containing gas. CONSTITUTION:A base material 2 having a carbon dioxide adsorbent bonded thereto is used as a peripheral wall of through holes 4 and the throughholes 4 are set to passages of carbon dioxide-containing gas to adsorb carbon dioxide in the gas passing through said passages. In this case, as compared with a conventional case allowing gas to flow through the gaps between a large number of pellets, the flow of gas becomes smooth and pressure loss is reduced. Further, by bonding the carbon dioxide adsorbent to the peripheral wall of the throughholes 4, the contact area of the adsorbent with gas becomes large. Since gas flows through the passages in the through holes 4 independently, when the flow velocity distribution of gas at the inlets of the passages is uniformized, the flow velocity of the gas in the through-holes 4 where carbon dioxide is adsorbed becomes uniform.

IPC: F16L55/00
Filed: 1990-11-27
Abstract: PURPOSE:To prevent a water break of a trap in a sanitary equipment and generation of a bad smell following the water break at the time of suddenly draining a large amount by integrally connecting an inner layer unit, formed of synthetic resin, to an outer layer unit, formed of fireproof heat insulating material, and providing a helical rib or protrusive streak in an internal surface of the inner layer unit. CONSTITUTION:A drain vertical pipe 1 has a double-pipe structure formed of an inner layer unit 2 and an outer layer unit 3 provided in the periphery of the inner layer unit. A plurality of ribs 2a...2a are helically formed over a total length of the vertical pipe 1 in an internal surface of the inner layer unit 2 consisting of synthetic resin. On the other hand, the outer layer unit 3 is constituted of fireproof heat insulating material and integrally connected to a peripheral surface of the inner layer unit 2. Thus by dropping drain to flow while helically turning and also forming an air core in a center part of the vertical pipe 1 by centrifugal force, a dropping speed of the drain is averaged and reduced further to suppress a turbulent flow, on the other hand, to automatically perform ventilation of a pipe line by the air core. As a result, even in the case of a large amount of one drain rapidly flowing in the drain vertical pipe 1, abnormality by a piston phenomenon is suppressed or prevented.
