Title: Alarm device for discrimination reproducing circuit
Inventor: ITAYA EIJI
IPC: H04L1/20
Filed: 1979-05-26
Abstract: PURPOSE:To ensure the assured working of the alarm circuit without giving any effect to the output of the main signal, by providing another set of discrimination reproducing circuits of different threshold levels and in parallel each other. CONSTITUTION:The threshold voltage of comparators 3a and 3b are set to value B and D by variable resistors 6-1 and 6-2 each. And the level of voltage D is set to the higher value than the noise level and outside the discrimination uncertain width linking the upper and lower parts of voltage B. As a result, output OP-1 of comparator 6-1 has the signal containing the noise; while the output OP-2 of comparator 6-2 has the output signal which is not affected by the noise respectively. Accordingly, the output of logic circuit 5 delivers H when either output OP-1 or OP-2 becomes 1, and output L is obtained either one or both of the above outputs become O. Thus the clear detection is secured for the fault of discrimination reproducing circuit 1 or 3 or the OFF-state of the input signal if the alarm is set to be given in the case of output L.

Title: Gain control circuit
Inventor: OZASA MASAYUKI
IPC: H04N5/262
Filed: 1989-03-20
Abstract: PURPOSE:To realize a gain control circuit operable with simple and small sized constitution by providing a pulse width expansion circuit and expanding the time width of a synchronizing signal. CONSTITUTION:A synchronizing separator circuit B extracts a synchronizing signal of a video signal and a pulse width expansion circuit C expands the time width of the synchronizing signal extracted by the synchronizing separator circuit B into nearly twice. Then a control signal inputted from a control signal input terminal 3 and converted by a control circuit E is switched according to an output signal of the pulse width expansion circuit C at a gate circuit D. That is, the control of an amplifier A is released for the expanded synchronizing signal period and the amplifier is operated with a gain according to the output of the control circuit for the other period. Thus, a highly accurate clock and a large sized decoder circuit are not required and a gain control circuit acted accurately with simple constitution is obtained.

Title: Method and equipment for executing bus arbitration protocol in data processing system
Inventor: JIEIMUZU BII GARETSUTO
IPC: G06F12/08
Filed: 1993-03-03
Abstract: PURPOSE: To obtain a data processing system to execute snoop retrial protocol by using an arbiter. CONSTITUTION: A plurality of bus masters 12, 16, 17 are linked with common share buses 20, 22, 24. Each bus master starts a bus transaction or snoops a bus transaction arisen in the common share bus. When a start processor requests an access to a dirty cache line in a memory 18, a snoop bus master asserts a common address retrial (ARTRY*) signal and informs it to the start processor that it gives up an ownership right of the common share bus 20 and retries a bus transaction. All potential bus masters delete their bus requests. Thus, the snoop processor obtains the ownership right of the common share bus 20 to execute snoop/copy-back.

Title: Magnetic brush developing carrier
Inventor: AOKI TAKAYOSHI
IPC: G03G9/113
Filed: 1984-04-03
Abstract: PURPOSE:To enhance electrostatic charge raising velocity and to prevent decrease of charge amt. in running, fogging in an early stage, and staining in a copying machine by covering magnetic core particles with a coating layer made of a methyl methacrylate type copolymer. CONSTITUTION:The surfaces of the magnetic core particies are treated with a methyl methacrylate type copolymer having a number average mol.wt. of 10,000-50,000, and a coating film is formed on the surfaces of the core material by chemical combination or adsorption. Such a coating layer is obtained, e.g., by dissolving said copolymer in a solvent, immersing the core particles, and baking them at high temp. The coating carrier thus obtained is superior in intimate adhesion between the core material and the coating layer, high in mechanical strength, less liable to be stained with a toner, and therefore, long in life. Since the use of such a carrier enhances a charge raising velocity, and does not decrease charge amt. in running, it can prevent fogging in an early stage and staining in the machine.

Filed: 1978-06-02
Abstract: PURPOSE: To prepare a hydrocarbon fuel composition having excellent low-temperature fluidity, by adding ethylenic unsaturated dicarboxylic acid and an α-olefin to a hydrocarbon fuel.  
     CONSTITUTION: A fuel composition composed of (A) 100 part by weight of a hydrocarbon fuel and (B) 0.001W0.5 parts, pref. 0.01W0.2 parts of a low-temperature fluidity improving agent consisting of a copolymer of (a) an ethylenic unsaturated dicarboxylic acid, its anhydride or its derivative, and (b) an α-olefin having 20W60 carbon atoms in a molecule. An α-olefin having a carbon number of less than 20 gives a copolymer having only poor effect to improve the low-temperature fluidity, and an α-olefin having a carbon number of larger than 60 is not recommended by its unavailability. When the amount of the copolymer is less than 0.001 part, the fluidity-improving effect is not sufficient, and the amount higher than 0.5 parts is not efficient for the further improvement of the low-temperature fluidity.

Title: Chuck
Inventor: TONOMURA TAKASHI
IPC: B23B31/08
Filed: 1986-03-25
Abstract: PURPOSE:To prevent the loosening of a turning cylinder by causing a difference between the inclinations of one or a plurality of needle rollers arranged on the external surface of a chuck cylinder a slant with a retainer and the inclinations of remaining rollers, and between the rotating directions thereof. CONSTITUTION:A roller hole 2 slant toward the left side from a YY axis is formed on the tapered surface of a retainer 1 and a needle roller 3 is coupled thereto. In this state, when the retainer 1 has been turned clockwise, the roller 3 turns along the external surface of a chuck cylinder, while rotating in an (a) direction. A needle roller 31 tends to turn in a (a') direction, but when there is a large number of rollers 3, the roller 31 is pulled and moves in a (a'') direction due to a differential slip. Also, many rollers 3 as tightened tend to slacken in a (b) direction, but the roller 31 exposed to a force in the (b) direction can stop the loosening of the roller 3. The inclinations of the rollers are combined to suit the weight of the turning cylinder and the chuck cylinder in such a way that alpha1 is for the roller 32 alpha2 for the roller 33 and alpha3 for the roller 34.
