Title: Record player
Inventor: AZUMA KOUICHI
IPC: G11B3/10
Filed: 1982-02-01
Abstract: PURPOSE:To prevent noise due to mechanical vibration from being introduced to a reproduced output, by coupling the 2nd base to the 1st base supporting the reproducing system such as a linear tracking arm via a bushing made of a viscoelastic substance. CONSTITUTION:The motor and the drive side of a gear reducer mechanism are supported with the separate 2nd base 14, and the 1st base 13 supporting the reproduction system such as a slide shaft 5 supporting the linear tracking arm 3 slidably and a guide plate 11 is coupled with a bushing 15 made of a viscoelastic substance such as rubber. In the figure, 16 is a fixing screw. The vibration of the driving side of the motor is attenuated and absorbed with the bushing 15 made of the viscoelastic substance and not delivered to the 1st base plate 13. Thus, the linear tracking arm 3 is prevented from invasion of the mechanical vibration, and introduction of noise to the reproducing sound is prevented.

Title: Combustion control device
Inventor: UEMATSU HIDEO
IPC: F23N5/18
Filed: 1983-02-01
Abstract: PURPOSE:To enable to keep the air fuel ratio nearly constant so as to maintain the stability and high efficiency of combustion by a method wherein the quantity of gas or air is controlled by the output signal of a differential pressure sensor arranged between on the upstream sides of the second gas throttling part in a fuel gas route and of the air throttling part in a combustion air route. CONSTITUTION:Fuel gas with a pressure of P1 flows upstream a fuel gas route 1 in a gas flow rate control means 2 to be controlled into the fuel gas with a pressure of P2 and then flows further in a first gas throttling part 3 in order to leave the part 3 in a form of the fuel gas with a pressure of PG and, after that, passes through a second gas throttling part 4 to be led to a mixing part 5. On the other hand, combustion air is past through an air flow rate control means 6 and a combustion air route 7 and reduced its pressure to a predetermined pressure PA at an air throttling part 8 and led to the mixing part 5. The change of the temperature of delivered hot water is resulted, when load is changed by changing the quantity of hot water passing through a hot water delivery pipe 13 of the like. A fan controller 14 controls the rotational frequency of a fan 6 based upon said changed temperature detected by a temperature detector 12 so as to bring the temperature of delivery hot water equal to the set temperature. Consequently, the differential pressure due to PA and PG is generated at a differential pressure sensor 9 with a timing almost same as that corresponding to the pressure PA on the upstream side of the air throttling part 8. Said differential pressure is processed at a gas flow rate controlling 15 so as to control the gas pressure proportional control valve 2 in order to realize the relationship PA=PG.

IPC: C10J3/54
Filed: 1995-02-02
Abstract: PURPOSE: To provide a reductor burner for a coal gasification oven which is so constructed as to prevent troubles such as those in feeding coal for gasification caused by slag deposited and accumulated on the burner. CONSTITUTION: A reductor burner 9 is installed rotatably and rotated through a gear 17 by a driving motor 16. A water-cooled scraper 21 with a rectangular cross-section is installed just below the burner 9. When the burner 9 is rotated, slag deposited on the burner 9 is rotated too, hits against the scraper 21 to be scraped, and falls down. Hence, a cylindrical slag does not grow on the burner 9.

Title: Battery
Inventor: MORIGAKI KENICHI
IPC: H01M4/62
Filed: 1982-02-02
Abstract: PURPOSE:To obtain a battery having a high voltage, a good flatness and a large capacity by mixing a carbon fluoride with carbon which has a large specific surface area and a high adsorptive property, such as carbon black. CONSTITUTION:An organic electrolyte battery is constituted by using a negative active material made of a light metal such as lithium, and a positive active material made of a carbon fluoride represented by the equation, (C2F)n. In such a battery, by mixing the carbon fluoride with carbon having a large specific surface area and a high adsorptive property, the electric-discharge characteristic can be improved without causing any voltage reduction, and the utilization rate of the active material can be greatly improved. Such an effect markedly appears when carbon with a specific surface area of over 200m<2>/g is employed. This effect is caused since fluorine which is contained in the carbon fluoride and has a small binding strength can be fixed to carbon having a high adsorptive property without deteriorating the activity of the fluorine.

Title: Fluid seal device
Inventor: HATTORI HITOSHI
IPC: F16J15/447
Filed: 1988-01-28
Abstract: PURPOSE:To reduce friction loss without needing particularly high accuracy in piston motion by providing circumferentially grooves on the surface of a ring opposed to a cylinder or piston and attached to either the cylinder or piston between the cylinder and the piston. CONSTITUTION:While a piston 2 is guided by guide rings 6, 7 to reciprocate in a cylinder 1, fluid in the cylinder 1 is prevented from leakage by a ring 8. Namely, the fluid tends to pass through guide portions 10 having no sealing action between the cylinder 1 and ring 8 and a region provided with a plurality of grooves 11. However, in the region between the guide portions 10 is produced a labyrinth effect by a plurality of the grooved 11 to prevent fluid from leakage so that the sealing performance here is equal to that of a normal reciprocation type labyrinth packing. Also, the fluid tending to pass through between the piston 2 and ring 8 is sealed by one end A of the ring 8 and the one end A is sealed by the ring 8 pressed toward the outside of cylinder 1 due to the pressure action of fluid.

Abstract: PURPOSE:To debug a program in the same circumstances as the occurrence of trouble at the time of test by providing two kinds of start mode of the independent execution mode and the interlocking execution mode for a test tool and a debugging tool. CONSTITUTION:A test tool 2 started in the interlocking execution mode by a user starts a debugging tool 3 in the interlocking execution mode and waits for response. The debugging tool 3 executes debugging commands from the user similarly to the independent execution mode. At the time of instructing the program execution by the debugging command, the test tool 2 is requested to perform analysis and execution processings of an instructed part before program execution of a test program 4. The test tool 2 performs the processing similarly to the independent execution mode and informs the debugging tool 3 of termination and waits for response. The debugging tool 3 receives the report of termination and executes the program and executes debugging commands from the user. Thus, the user debugs the program in the same circumstances as the test.
